Description

Technical Field

[0001] The embodiments relate to a range-measuring camera device. Background Technology

[0002] Three-dimensional content is used in many fields such as education, manufacturing, autonomous driving, gaming, and culture, and depth maps are required to capture this content. A depth map represents spatial distance information and perspective information about a point in a two-dimensional image relative to another point. Methods for acquiring depth maps include projecting infrared (IR) structured light onto an object, using stereo cameras, and time-of-flight (TOF) methods.

[0003] Time-of-Flight (TOF) methods, or structured light methods, use light within the infrared wavelength range and have recently been explored for biometric identification utilizing the characteristics of this range. For example, it is known that the shape of veins distributed in areas such as the fingers does not change throughout life from fetal development and varies from person to person. Therefore, a camera device equipped with an infrared light source can be used to identify vein patterns. To this end, after photographing the fingers, each finger can be detected based on its color and shape by removing the background, and the vein pattern of each finger can be extracted from the color information of each detected finger. In other words, the average color of the fingers, the color of the veins distributed in the fingers, and the color of the lines on the fingers may differ from each other. For example, the color of the veins distributed in the fingers may be a lighter red than the average color of the fingers, while the color of the lines on the fingers may be darker than the average color of the fingers. Using these features, a value approximating the vein can be calculated for each pixel, and the vein pattern can be extracted using the calculation results. Furthermore, a person can be identified by comparing the extracted vein pattern of each finger with pre-registered data. As mentioned above, ranging and location identification can be performed using light emission and light reception.

[0004] Additionally, a 3D camera may include at least one optical component capable of controlling light emitted from a light source. However, a problem exists that it is difficult to determine whether the optical component is functioning correctly while the camera device is operating. For example, when the optical component is damaged, the accuracy of light emitted from the light source, reflected onto an object, and incident on the sensor may decrease, thereby reducing the reliability of the depth map.

[0005] Therefore, a new camera device is needed that can solve the above problems.

[0006] In addition, camera equipment is required to improve the reliability of optical axis alignment, eye safety, and impact resistance. Summary of the Invention

[0007] Technical issues

[0008] The embodiments are intended to provide a range-measuring camera device for easily detecting abnormal conditions of moving optical components.

[0009] The embodiments aim to provide a ranging camera device for preventing human beings or others from being harmed by the energy of light signals (e.g., eye safety) by controlling the light output in response to abnormal states.

[0010] The embodiments are intended to provide a camera device that can determine whether it is operating normally.

[0011] Additionally, the embodiments are intended to provide a camera device with improved security.

[0012] The purpose of this embodiment is not limited to this, and will also include purposes or effects recognized from the configurations or embodiments described below.

[0013] Technical solution

[0014] A camera device according to an embodiment of the present invention includes: a substrate; a light emitting part including a light source disposed on the substrate, a holder disposed on the substrate, an optical component disposed on the light source, a driving part (configured to move the optical component along an optical axis), and a photodetector disposed on the substrate; a light receiving part including an image sensor disposed on the substrate; and a controller configured to control the optical component or the light source using an output value received from the photodetector.

[0015] The light source can overlap with the optical components along the optical axis, and the photodetector can overlap with the optical components along the optical axis.

[0016] The optical component can be moved along the optical axis on the substrate from a first height to a second height, which can be the height when the optical component is set at the highest height, and the first height can be the height when the optical component is set at the lowest height.

[0017] The first line and the second line can form a first angle. The first line can be the line connecting the intersection of the photodetector and the optical axis with the lowest surface of the optical component, and the second line can be the line connecting the intersection of the photodetector and the optical axis with the highest surface of the light source. The first angle can range from 10 degrees to 80 degrees.

[0018] The part where the first line connects to the photodetector can be the central region of the photodetector, and the part where the second line connects to the photodetector can also be the central region of the photodetector.

[0019] The controller can detect abnormal conditions when the first output value of the photodetector is greater than the critical range of the photodetector, or when the second output value of the photodetector is less than the critical range of the photodetector.

[0020] The controller can detect an abnormal state when the slope between the first output value and the second output value of the photodetector is positive.

[0021] The controller can detect an abnormal state if the slope between the first output value and the second output value of the photodetector falls within a predetermined value.

[0022] The controller can reduce or block the current applied to the light source.

[0023] When the first output value of the photodetector deviates from the critical range of the photodetector, the controller can adjust the current applied to the light source.

[0024] The optical components may include a lens barrel and at least one lens housed in the lens barrel, and include a reflective member disposed on the lower surface of the lens barrel or the lens closest to the light source among the at least one lenses.

[0025] A camera device according to one embodiment includes a light emitting unit and an image sensor, wherein the light emitting unit includes a light source, a light receiving element, a diffuser disposed on the light source, and a shutter member disposed on the diffuser. The light receiving element is configured to receive a portion of the light emitted from the light source, and the opening and closing of the shutter member is controlled by the amount of light received by the light receiving element.

[0026] The camera device may include a controller configured to control the opening and closing of the shutter component.

[0027] When the shutter component is closed, the controller can open the shutter component when a portion of the light emitted from the light source is reflected by the shutter component and incident on the light receiving element, and when the light received by the light receiving element meets the set light quantity range.

[0028] When the shutter component is closed, if a portion of the light emitted from the light source is reflected by the shutter component and incident on the light receiving element, and if the light received by the light receiving element does not meet the set light quantity range, the controller can keep the shutter component closed.

[0029] The camera device may include a detection unit connected to the controller, and the controller may close the shutter component when the impact or acceleration detected by the detection unit exceeds a set value.

[0030] The light emitting part may include: a first housing disposed on the light source and including a first opening that vertically overlaps with the light source; and a second housing disposed on the diffuser and including a second opening that vertically overlaps with the diffuser, and a light receiving element may be disposed between the first housing and the second housing.

[0031] The camera device may include a light receiving unit spaced apart from the light emitting unit, wherein the light receiving unit may include: the image sensor spaced apart from the light source and the light receiving element; a third housing disposed on the image sensor and including a third opening vertically overlapping the image sensor; and a lens module disposed on the image sensor.

[0032] The camera device may also include cover members disposed on the light emitting part and the light receiving part.

[0033] Additionally, a method for confirming the normal operation of a camera device according to one embodiment includes: closing the shutter component; emitting light from a light source toward the shutter component; receiving a portion of the light reflected by the shutter component by a light receiving element; and controlling the opening and closing of the shutter component, wherein the control of the opening and closing of the shutter component includes determining the amount of light received by the light receiving element, and controlling the opening and closing of the shutter component based on the received amount of light.

[0034] In the control of opening and closing of the shutter component, when the light received by the light receiving element deviates from the set light amount range, the shutter component can remain closed.

[0035] In the control of opening and closing of the shutter component, the shutter component can open when the light received by the light receiving element meets the set light amount range.

[0036] The control of opening and closing of the shutter component may further include detecting impact or acceleration, and in the detection of impact or acceleration, when the impact or acceleration is detected to exceed a set value, the shutter component may close.

[0037] Beneficial effects

[0038] According to one embodiment, a camera device can be flexibly driven according to the needs of various applications by changing the light pattern or light signal based on various variables (such as the distance and resolution to an object).

[0039] In addition, a camera device can be made that can easily detect abnormal conditions of moving optical components.

[0040] According to this embodiment, a camera device can be implemented that controls light output in response to an abnormal state to prevent the human body or other objects from being harmed by the energy of the light signal.

[0041] The camera device according to this embodiment can effectively determine whether it is operating normally. Specifically, by placing a light receiving element in the light emitting section, the camera device can effectively detect whether the light emitting section is operating normally, for example, whether the components are damaged or separated.

[0042] Furthermore, the camera device according to this embodiment can have improved security. Specifically, the camera device can determine the state of damage and separation of the diffuser based on the light incident on the light receiving element. Therefore, when a person is in front of the camera device, direct light from the light source can be prevented from shining on sensitive areas (such as the eyes and skin).

[0043] The various beneficial advantages and effects of the present invention are not limited to those described above, and will be more readily understood in the process of describing specific embodiments of the present invention. Attached Figure Description

However, the type of optical device is not limited to these; any device used for capturing images or photographs can be included in an optical device.

[0106] The optical device may include a main body. This main body may be strip-shaped. Alternatively, the main body may have various structures, such as sliding, folding, or oscillating (where two or more sub-bodies are connected in a rotatable manner that allows relative movement). The main body may include a shell (outer shell, housing, or cover) forming the exterior. For example, the main body may include a front shell and a rear shell.

[0111] Figure 1 This is a perspective view of a camera device according to one embodiment. Figure 2 It is along Figure 1 The sectional view taken by line A-A' in the middle. Figure 3 This is an exploded perspective view of the camera device according to this embodiment.

[0112] Reference Figures 1 to 3The camera device 10 according to this embodiment may include a light emitting unit 1, a light receiving unit 2, a connecting unit 3, a main substrate 4, an extension substrate 5, a connecting substrate 6, and a connector 7. Additionally, the camera device 10 according to this embodiment may include a controller. The controller may be located on any one of the light emitting unit 1, the light receiving unit 2, the connecting unit 3, and the main substrate 4. Hereinafter, the controller will be described as a component disposed in the light emitting unit 1.

[0113] Furthermore, in this specification, the camera device may be a concept that "has only one of the light emitting part 1 and the light receiving part 2". Alternatively, the camera device may be a concept that "includes a substrate (e.g., a main substrate 4) electrically connected to either the light emitting part 1 or the light receiving part 2".

[0114] First, the light emitting unit 1 can be a light-emitting module, a light-emitting unit, a light-emitting component, or a light-emitting device. The light emitting unit 1 can generate light or a light signal, and then illuminate an object with the light or light signal. In the following text, light or light signal can be used interchangeably. At this time, the light emitting unit 1 can generate and output a light signal in the form of a pulse wave or a continuous wave. The continuous wave can be in the form of a sine wave or a square wave.

[0115] Furthermore, by generating light signals in the form of pulsed waves or continuous waves, for example, a TOF camera device can detect the phase difference between the light signal output from the light emitting unit 1 and the input light that is reflected from the object O and input to the light receiving unit 2 of the TOF camera device. In this specification, output light can refer to the light signal output from the light emitting unit 1 and incident on the object O, while input light or reflected light can refer to the light signal output from the light emitting unit 1, reaching the object O, being reflected from the object O, and then input to the TOF camera device. Furthermore, from the object O's viewpoint, output light can be incident light, and input light can be reflected light.

[0116] The light emitting unit 1 illuminates the object O with the generated light signal for a predetermined integration time. Here, the integration time refers to one frame period. When multiple frames are generated, the set integration time is repeated. For example, when a TOF camera device captures the object at 20 FPS, the integration time is 1 / 20 [sec]. In addition, when 100 frames are generated, the integration time can be repeated 100 times. Therefore, the light source can also emit light within a frame period.

[0117] Alternatively, the light emitting unit 1 can also generate multiple optical signals with different frequencies. The light emitting unit 1 can sequentially and repeatedly generate multiple optical signals with different frequencies. Alternatively, the light emitting unit 1 can also generate multiple optical signals with different frequencies simultaneously.

[0118] The light emitting unit 1 may include a light source LS. The light source LS can generate light. The light source LS can output light. The light source LS can illuminate light. The light generated by the light source LS may be infrared light with a wavelength of 770 nm to 3000 nm. Alternatively, the light generated by the light source LS may be visible light with a wavelength of 380 nm to 770 nm. The light source LS may include all kinds of elements configured to generate and output light. For example, the light source LS may include light-emitting diodes (LEDs) and vertical-cavity surface-emitting lasers (VCSELs). For example, when the light source LS is a VCSEL, multiple emitters may be formed in a horizontal or vertical arrangement on a plane perpendicular to the optical axis. Furthermore, when the light is output in a point form, the point form may correspond to the arrangement of the emitters. For example, when the emitters are 3x3 (width x length), the point form of light may also be 3x3.

[0119] Additionally, the light source LS may include multiple light-emitting diodes arranged in a regular pattern. Alternatively, the light source LS may include organic light-emitting diodes (OLEDs) or laser diodes (LDs).

[0120] The light emitting unit 1 may include an optical modulation unit configured to modulate light. The light source LS can generate a light signal in the form of a pulsed wave or a continuous wave by repeatedly blinking (on / off) at specific time intervals. This specific time interval may be the frequency of the light signal. The blinking of the light source LS can be controlled by the optical modulation unit. The optical modulation unit can control the blinking of the light source LS to control the light source LS to generate a light signal in the form of a continuous wave or a pulsed wave. The optical modulation unit can control the light source LS to generate a light signal in the form of a continuous wave or a pulsed wave through frequency modulation, pulse modulation, etc. This optical modulation unit may be located in a controller. Therefore, it should be understood that the controller can control the optical modulation unit to block (interrupt or turn off) or provide (turn on) the light source's output of the light signal, as described below.

[0121] The light emitting unit 1 may include a diffuser (not shown). This diffuser (not shown) may be a diffusion lens. The diffuser (not shown) may be positioned in front of the light source LS. Light emitted from the light source LS can pass through the diffuser (not shown) to be incident on the object O. The diffuser (not shown) can change the path of the light emitted from the light source LS. The diffuser (not shown) can diffuse the light emitted from the light source LS. The diffuser (not shown) may also be located within or above the first optical component, which will be described below.

[0122] Specifically, the light emitting unit 1 may include the aforementioned light source LS, housing 110, first optical component 120, first lens holder 130, driving unit (which includes driving magnet part 140 and driving coil part 150), elastic part 160, side substrate 170 and control element SS.

[0123] First, the housing 110 can be located inside the cover 400, which will be described below. The housing 110 can be connected to the first lens holder 130, the side plate 170, the drive coil portion 150, and the elastic portion 160, which will be described below.

[0124] The housing 110 may include an open lens barrel receiving portion. The aforementioned first lens holder 130 and drive coil portion 150 may be located in this lens barrel receiving portion.

[0125] The first optical component 120 may be located within the housing 110. The first optical component 120 may be held and coupled to the housing 110 by a first lens holder 130, which will be described below. Additionally, the first lens holder 130 may be movable along the optical axis within the housing 110 or the base 200. The first optical component 120 may also move along the optical axis together with the first lens holder 130.

[0126] The first optical component 120 may consist of a lens and a first lens barrel (which houses multiple lenses). The lens may consist of multiple optical elements or lenses. For example, the first optical component 120 may consist of multiple lenses.

[0127] Additionally, the first optical component 120 may include a convex lens, a concave lens, or a collimating lens. For example, the collimating lens may consist of multiple lenses and may have a field of view (FoI) of 60 to 120 degrees. The collimating lens can reduce the divergence angle of the light output from the light source. When the laser divergence angle of each opening of the vertical-cavity surface-emitting laser (VCESL) serving as the light source is 20 to 25 degrees, the divergence angle of the light passing through the collimating lens may be 1 degree or less.

[0128] Additionally, the first optical component 120 can replicate the optical signal output from the light source LS according to a preset replication mode. Therefore, the first optical component 120 may include a diffractive optical element (DOE) or a diffuser lens. For example, the first optical component 120 may include an optical component with a micrometer-scale or nanometer-scale structure.

[0129] The light signal (output light) emitted from the light source LS toward the object can pass through the first optical component 120 (i.e., the lens and the first lens barrel). In addition, the central axis of the first optical component 120 or the first lens holder 130 can be aligned with the optical axis of the light source LS.

[0130] The first lens holder 130 can be connected to the housing 110. Alternatively, the first lens holder 130 can be fixed to the housing 110. The first lens holder 130 can hold the first optical component 120, which consists of a plurality of optical elements.

[0131] The first lens holder 130 may include a lens receiving portion 131 on which the first optical component 120 is mounted. The first lens holder 130 can move up and down using a voice coil motor or the like, as described below. In other words, the first lens holder 130 can move up and down along the optical axis using an actuator (such as a voice coil motor). Therefore, as described below, light generated from a light source can be transformed into a planar or point form when passing through the first lens holder 130. Additionally, the first lens holder 130 may include a magnet mounting groove 132 (in which a drive magnet is mounted). For example, the first lens holder 130 may be the bobbin (winding shaft) of the first optical component 120.

[0132] Additionally, a threaded structure can be formed on the side surface of the lens receiving portion 131 to connect with the first optical component 120. Therefore, the first optical component 120 can move up and down in the housing 110 together with the first lens holder 130 by means of the drive portion described below.

[0133] Additionally, the side substrate 170 can be connected to the housing 110. The side substrate 170 can be located in a substrate recess 112, which is located on the side surface of the housing 110. Furthermore, the side substrate 170 can be electrically connected to the main substrate 4.

[0134] Additionally, the drive unit may include a drive magnet section 140 and a drive coil section 150.

[0135] The drive magnet section 140 may include a plurality of magnets. The plurality of magnets may be located in a magnet mounting groove 132, which is located on the side surface of the first lens holder 130.

[0136] The drive magnet section 140 can move the first lens holder 130 and the first optical component 120 vertically relative to the housing 110 through electromagnetic interaction with the drive coil section 150, as described below. Therefore, the separation distance from the light source LS disposed thereunder to the first optical component 120 and the first lens holder 130 can be increased or decreased. Furthermore, depending on the aforementioned separation distance, the output light can be in a planar form (or surface light source) or a point form relative to the aforementioned object (or point light source).

[0137] The drive coil portion 150 may include a plurality of coils, and the drive coil portion may be positioned on a side surface of the housing 110. Alternatively, the drive coil portion 150 may be positioned inside the housing 110. The drive coil portion 150 may be positioned facing the drive magnet portion 140. For example, the drive coil portion 150 may be positioned facing at least a portion of the drive magnet portion 140. Therefore, when current is applied to the drive coil portion 150, the first lens holder 130 may be moved by means of the electromagnetic interaction (e.g., Lorentz force) between the drive coil portion 150 and the drive magnet portion 140.

[0138] The drive coil portion 150 can be positioned in each coil mounting portion 114 formed on the side surface of the housing 110. The drive coil portion 150 can be electrically connected to the side substrate 170. For example, the drive coil portion 150 can be electrically connected to the side substrate 170 via wires or the like. Furthermore, since the side substrate 170 is connected to the housing 110 as described above, the drive coil portion 150 can also be positioned in the coil mounting portion 114 formed on the side surface of the housing 110 and can be connected to the housing. A detailed description will be given below.

[0139] The elastic part 160 can be provided on the housing 110. The elastic part 160 can be connected to the first lens holder 130 and the housing 110. The housing 110 can be connected and fixed to the main substrate 4 or the base 200, as will be described below. Alternatively, the first lens holder 130 can move up and down relative to the housing 110 by means of the aforementioned Lorentz force. The elastic part 160 can provide a preload for the vertical movement of the first lens holder 130 or the first optical component 120. Therefore, when the drive unit does not generate a Lorentz force, the first lens holder 130 can be held in a predetermined position relative to the housing 110. In addition, even when the drive unit generates a Lorentz force, the positional relationship between the first lens holder 130 and the housing 110 is maintained within a certain range, thereby improving the reliability of the camera device.

[0140] The control element SS can be electrically connected to the side substrate 170. Alternatively, the control element SS can be located on the side substrate 170. Furthermore, the control element SS can be configured to be spaced a predetermined distance from the aforementioned drive magnet section 140.

[0141] The control element SS may include a Hall sensor or a Hall IC. The control element SS can detect the magnetic force of the drive magnet section 140.

[0142] According to this embodiment, the control element SS can detect the strength of the magnetic field generated by the driving magnet and output position information of the first lens holder 130 or the first optical component 120 relative to the light source LS. Therefore, the controller can determine the defects of the first optical component 120 or the first lens holder 130 based on the position information provided by the control element SS, and control (turn on / off) the output of the light source LS in response to this determination result.

[0143] In this embodiment, the control element SS may include multiple control elements. The control element SS may include two sensors. The control element SS can detect the movement of the first lens holder 130 and the first optical component 120 in the optical axis direction. In this specification, the Z-axis direction is the optical axis direction or a vertical direction as a third direction. Additionally, the X-axis direction is a direction perpendicular to the Z-axis direction, and in this embodiment, it is a first direction from the light emitting part towards the light receiving part. Furthermore, the Y-axis direction is a direction perpendicular to both the X-axis and Z-axis directions, and is a second direction. The following description is based on this.

[0144] Furthermore, the light emitting unit 1 may also include a photodetector PD. The photodetector PD may include, for example, a light receiving element disposed in a charge-coupled device (CCD), a complementary metal-oxide-semiconductor (CMOS) linear image sensor, or a photodiode array. Light emitted from the light source LS is reflected by the first optical component 120, the first lens holder 130, etc., and the photodetector PD can receive the reflected light. Additionally, the photodetector PD can output an output value representing a detection quantity based on the amount of light received. For example, the photodetector PD can output an output value corresponding to the amount of light received. In other words, the output value can also increase as the amount of light received increases. Furthermore, the controller can detect abnormal states of the first optical component 120 and the light source LS based on the output value received from the photodetector PD to control the light source LS, etc. A detailed description will be given below.

[0145] The light receiving unit 2 may be a light receiving module, a light receiving unit, a light receiving assembly, or a light receiving device, and may be a component of a camera device. The light receiving unit 2 may receive light emitted from the light emitting unit 1 and reflected from the object (reflected light), and may convert the received light into an electrical signal.

[0146] The optical receiver 2 can generate input light corresponding to the optical signal output from the optical transmitter 1. The optical receiver 2 can be arranged side-by-side with the optical transmitter 1. The optical receiver 2 can be positioned next to the optical transmitter 1. The optical receiver 2 can be positioned in the same direction as the optical transmitter 1. With this configuration, the reception efficiency of the input light in the optical receiver 2 can be improved.

[0147] The light receiver 2 can receive reflected light during integration time and generate an electrical signal for this purpose. In this embodiment, the camera device can perform direct or indirect ranging through the light receiver 2. The light receiver 2 may also have a structure separate from the light emitter 1.

[0148] First, in the case of direct ranging, the camera device can measure the distance to the object by the time difference between the time point of receiving the reflected light and the time point of outputting the output light.

[0149] In addition, in the case of indirect ranging, the camera device can measure the distance to the object by combining a reference signal that is synchronized with the output light and has a different phase with the reflected light.

[0150] Direct ranging is easier to measure long distances than indirect ranging. It offers relatively high measurement speed due to its nanosecond-level switching speed and is more resistant to multiple echoes. In contrast, indirect ranging has the advantage of a lower switching speed but is easier to measure short distances, can be applied to multiple pixels, and requires less data.

[0151] The camera device according to the embodiment can perform the above-described direct TOF (or corresponding to direct ranging) or indirect TOF (or corresponding to indirect ranging). In other words, camera device 10 can be a camera device or camera device capable of measuring distance.

[0152] The light receiving unit 2 may include a second lens barrel 320, a second optical component 310, and an image sensor IS.

[0153] The second lens barrel 320 can be connected to the base 200, which will be described below. The second lens barrel 320 can be connected to the base, which will be described below, by means of a threaded connection or the like. Therefore, the second lens barrel 320 may include threads located on its side surface. The second lens barrel 320 may also be integrally formed with the second optical component 310. However, the invention is not limited thereto.

[0154] The second optical component 310 can be connected to the second lens barrel 320. The second optical component 310 can be connected to the base 200 via the second lens barrel 320. The second optical component 310 can be connected to the second lens barrel 320 by various connection methods. As described above, the second optical component 310 can be formed by threaded connection with the second lens barrel 320.

[0155] The second optical component 310 may include multiple lenses. Additionally, the second optical component 310 may be aligned with the image sensor IS below it. Therefore, reflected light passing through the second optical component 310 can be provided to the image sensor IS.

[0156] The image sensor IS can detect reflected light. Additionally, the image sensor IS can detect reflected light and output the detected reflected light as an electrical signal. In an embodiment, the image sensor IS can detect light having a wavelength corresponding to the wavelength of light output from the light source LS. For example, the image sensor IS can detect infrared light. Alternatively, the image sensor IS can detect visible light. The image sensor IS can include various image sensors configured to sense light.

[0157] In an embodiment, the image sensor IS may include: a pixel array configured to receive light passing through the second lens barrel 320 and the second optical component 310 and convert the received light into an electrical signal corresponding to the light; a driving circuit configured to drive a plurality of pixels included in the pixel array; and a readout circuit configured to read the analog pixel signal of each pixel. By comparing the analog pixel signal with a reference signal, the readout circuit can generate a digital pixel signal (or image signal) through analog-to-digital conversion. Here, the digital pixel signal of each pixel included in the pixel array can constitute an image signal, and when the image signal is transmitted in units of frames, it can be defined as an image frame. In other words, the image sensor can output multiple image frames.

[0158] Furthermore, the light receiving unit 2 may also include an image synthesis unit. The image synthesis unit may include an image processor configured to receive and process (e.g., interpolate and frame synthesis) an image signal from the image sensor IS. Specifically, the image synthesis unit can synthesize multiple frames of image signals (low resolution) into a single frame of image signals (high resolution). In other words, the image synthesis unit can synthesize multiple image frames contained in the image signal received from the image sensor IS and produce a synthesized image. The synthesized image generated by the image synthesis unit can have a higher resolution than the multiple image frames output from the image sensor IS. In other words, the image synthesis unit can generate a high-resolution image using super-resolution (SR) technology. The multiple image frames may include image frames generated by changing to different optical paths through the movement of filters F and F'. The image synthesis unit may be located inside or outside the light receiving unit 2.

[0159] Filters F and F' can be connected to the base 200. Filters F and F' can be disposed between the first lens holder 130 and the light source LS, or between the second lens barrel 320 and the image sensor IS. For example, filters F and F' can be disposed on each of the light emitting section 1 and the light receiving section 2. Therefore, filters F and F' can be disposed in the optical path between the object and the image sensor IS, or in the optical path between the object and the light source LS. Filters F and F' can filter light with a predetermined wavelength range.

[0160] Filters F and F' allow light of a specific wavelength to pass through. In other words, filters F and F' can block light by reflecting or absorbing light of a wavelength other than a specific wavelength. For example, filters F and F' allow infrared light to pass through while blocking light of wavelengths other than infrared. Alternatively, filters F and F' allow visible light to pass through while blocking light of wavelengths other than visible light. Each of filters F and F' can be an infrared bandpass filter. Therefore, filters F and F' can allow only infrared light to pass through. Alternatively, the optical component can be a separate fixed-focus lens or a variable-focus lens (e.g., a liquid lens) separate from the lens module.

[0161] Furthermore, filters F and F' can suppress the introduction of foreign objects into the light source LS, photodetector PD, and image sensor IS in each of the light emitting section 1 and the light receiving section 2. Therefore, the reliability of the camera device can be improved.

[0162] Furthermore, filters F and F' are movable. In this embodiment, filters F and F' can be tilted. When filters F and F' are tilted, the optical path can be adjusted. When filters F and F' are tilted, the path of light incident on the image sensor IS may change. For example, filter F' in the light receiver 2 can change the field of view (FOV) or the direction of the FOV of the incident light. In addition, in this embodiment, by changing the path of light entry when filters F and F' are tilted, high-resolution time-of-flight (TOF) can be achieved.

[0163] The cover 400 can be a bracket. The cover 400 can include a "cover can". The cover 400 can be configured to surround the light emitting part 1 and the light receiving part 2. The cover 400 can be connected to the housing 110 and the base 200. The cover 400 can accommodate the light emitting part 1 and the light receiving part 2. Therefore, the cover 400 can be located at the outermost part of the camera device.

[0164] Alternatively, the lid 400 can be made of a non-magnetic material. Alternatively, the lid 400 can be made of metal. Alternatively, the lid 400 can be made of a metal plate.

[0165] The cover 400 can be connected to the grounding portion of the main substrate 4. Therefore, the cover 400 can be grounded. Additionally, the cover 400 can block electromagnetic interference (EMI). In this case, the cover 400 can be referred to as an "EMI shielding can". As the final assembled component, the cover 400 can protect the product from external impacts. The cover 400 can be made of a material with low thickness and high strength.

[0166] Furthermore, in the camera device 10 according to the embodiment, the light emitting unit 1 and the light receiving unit 2 can be disposed on the main substrate 4 (printed circuit board (PCB)). The main substrate 4 can be electrically connected to the light emitting unit 1 and the light receiving unit 2.

[0167] Additionally, in the camera device 10, the connecting part 3 can be electrically connected to the main substrate 4. The connecting part 3 can be connected to the configuration of the optical device. The connecting part 3 may include a connector 7 connected to the configuration of the optical device. The connecting part 3 may include an extension substrate 5, on which the connector 7 is disposed and which is connected to the connecting substrate 6. The extension substrate 5 may be a PCB, but is not limited thereto.

[0168] Furthermore, in camera equipment, the connecting substrate 6 can connect the main substrate 4 and the extension substrate 5 of the connecting portion 3. The connecting substrate 6 can be flexible. The connecting substrate 6 can be a flexible printed circuit board (flexible PCB (FPCB)).

[0169] In addition, the main substrate 4, the connecting substrate 6, and the extension substrate 5 can be formed as a whole or separately.

[0170] In addition, the light emitting part 1 and the light receiving part 2 can be located on the main substrate 4, and the light emitting part 1 and the light receiving part 2 can be electrically connected to the main substrate 4.

[0171] The camera device may include a reinforcing plate 8. The reinforcing plate 8 may include reinforcing members. The reinforcing plate 8 may be disposed on the lower surface of the main substrate 4. The reinforcing plate 8 may be made of stainless steel.

[0172] Furthermore, the light receiving unit 2 may include a lens driving device. In other words, the light receiving unit 2 may include a voice coil motor (VCM). Additionally, the light receiving unit 2 may include a lens driving motor. Furthermore, the light receiving unit 2 may include a lens driving actuator. With this configuration, as described above, the light receiving unit 2 according to the embodiment can tilt the filter F'. Furthermore, when the filter F' is tilted, the optical path of the input light passing through the filter F' can be repeatedly moved according to a predetermined rule. Therefore, the light receiving unit 2 can use multiple image information converted by the image sensor according to the tilt of the filter F' to output high-resolution image information and provide the output image information to an external optical device.

[0173] Figure 4 This is a perspective view showing the housing of the light emitting part according to an embodiment. Figure 5 This is a top view of the housing of the light emitting part according to an embodiment. Figure 6 This is another perspective view of the housing of the light emitting part according to an embodiment.

[0174] Reference Figures 4 to 6 According to the embodiment, the housing 110 of the light emitting part may include a housing hole 111, a substrate groove 112, a hole 113, a coil mounting part 114, and a mounting protrusion 115.

[0175] The housing hole 111 can be located at the center of the housing 110. The first optical component, the first lens holder, and the drive unit can be disposed in the housing hole 111.

[0176] In this embodiment, the housing 110 may include a housing side portion 110k1, a second housing side portion 110k2, a third housing side portion 110k3, and a fourth housing side portion 110k4. Housing side portions 110k1 to 110k4 refer to portions located on each side of the housing 110. Housing side portion 110k1 may be interchanged with the first housing side portion.

[0177] Specifically, the housing side portion 110k1 and the second housing side portion 110k2 can be configured to face each other. Furthermore, the housing side portions 110k1 and the second housing side portion 110k2 can be configured to be spaced apart from each other in a second direction (Y-axis direction). In other words, the housing side portions 110k1 and the second housing side portion 110k2 can be symmetrically arranged in a first direction (X-axis direction) or a third direction (Z-axis direction).

[0178] The third housing side portion 110k3 and the fourth housing side portion 110k4 can be configured to face each other. Furthermore, the third housing side portion 110k3 and the fourth housing side portion 110k4 can be located between housing side portion 110k1 and the second housing side portion 110k2. Additionally, the third housing side portion 110k3 and the fourth housing side portion 110k4 can be configured to be spaced apart from each other in a first direction (X-axis direction). In other words, the third housing side portion 110k3 and the fourth housing side portion 110k4 can be symmetrically arranged in a second direction (Y-axis direction) or a third direction (Z-axis direction).

[0179] In this embodiment, the substrate recess 112 can be located on the side of the housing 110 that has the maximum separation distance from the light receiving unit. Therefore, the substrate recess 112 can be located in the third housing side 110k4 of the housing 110. With this configuration, the influence of electromagnetic waves generated by electrical signals in the light receiving unit on the driving light emitting unit can be minimized.

[0180] In this embodiment, the housing 110 may have a rectangular shape in the XY plane. However, the invention is not limited to this, and the housing 110 may be formed in various shapes.

[0181] Additionally, a connecting protrusion for connection with the side substrate can be positioned in the substrate recess 112. The connecting protrusion can extend outward from the outer surface of the third housing side 110k3 of the housing 110. Furthermore, a connecting hole is provided in the side substrate, and the connecting protrusion is inserted into the connecting hole so that the side substrate and the housing 110 can be connected to each other.

[0182] The hole 113 can overlap with the substrate groove 112 in the first direction (X-axis direction) and the second direction (Y-axis direction).

[0183] In this embodiment, the hole 113 can pass through the outer surface 110b and the inner surface 110a of the housing. Therefore, the hole 113 can be located in the third housing side portion 110k3. The hole 113 can be located below the mounting portion 114, which will be described below. Therefore, even when the control element is placed in the hole 113, the control element will not overlap with the drive coil portion in the first direction (X-axis direction) or the second direction (Y-axis direction). In addition, the control element can be easily electrically connected to the side substrate and is configured to face the magnet in the hole 113. Furthermore, the position of the control element connected to the housing 110 is fixed so that the position of the drive magnet portion can be accurately measured.

[0184] The coil mounting portion 114 can be positioned on the inner surface 110a of the housing 110. In an embodiment, the coil mounting portion 114 can extend inward from the inner surface 110a of the housing 110. Therefore, the maximum separation distance W1 faced by the inner surface 110a of the housing 110 can be greater than the maximum separation distance W2 faced by the coil mounting portion 114. Furthermore, in this specification, "inward" can be a direction toward the central axis HX of the housing hole 111. Alternatively, "inward" can be a direction from the housing toward the first optical component. Additionally, "outward" can be a direction from the first optical component toward the housing, i.e., the opposite direction to "inward". The central axis HX of the housing hole 111 can be an axis passing through the intersection of the bisecting lines that divide the housing 110 into two equal parts in the first direction (X-axis direction) and the second direction (Y-axis direction), and parallel to the third direction (Y-axis direction).

[0185] Additionally, at least one groove IH may be located on the inner surface 110a of the housing 110. An adhesive component (such as epoxy resin) may be applied to said at least one groove IH. Thus, the coil on the coil mounting portion 114 can be connected to the housing 110.

[0186] Furthermore, the upper surface of the coil mounting portion 114 can be flat. Therefore, the drive coil portion can be easily mounted, and the vertical movement of the first lens holder can be precisely performed based on the electromagnetic interaction between the drive coil portion and the drive magnet portion.

[0187] Additionally, the coil mounting portion 114 may include a mounting groove 114h that protrudes downward (or recedes upward) from the third housing side portion 110k3. The mounting groove 114h may be positioned corresponding to the aforementioned hole 113, and may be a groove formed downward from the coil mounting portion 114. The mounting groove 114h may have a shape that protrudes downward and recedes upward.

[0188] The control element, which will be described below, can be housed in the mounting groove 114h. Therefore, the control element can at least partially overlap with the drive coil portion in the third direction (Z-axis direction). A detailed description of this will be given below.

[0189] Furthermore, the drive coil section can have a closed-loop shape as described below. Therefore, the coil mounting section 114 can also have a closed-loop shape corresponding to the shape of the drive coil section.

[0190] The mounting protrusion 115 can be connected to and positioned inside the coil mounting portion 114. Therefore, since the mounting protrusion 115 is positioned inside the coil mounting portion 114, it can at least partially overlap with the first lens holder positioned inside the coil mounting portion 114. Thus, the mounting protrusion 115 can serve as a stop for the vertical movement of the first lens holder.

[0191] Furthermore, the upper surface of the mounting protrusion 115 may have a stepped portion with respect to the coil mounting portion 114. In other words, the upper surface of the mounting protrusion 115 may be located above the coil mounting portion 114. With this configuration, the mounting protrusion 115 can easily prevent the drive coil portion from separating from the coil mounting portion 114.

[0192] For example, the coil mounting portion 114 can be formed as a bracket extending inward from the inner surface of the housing 110. In this specification, "inward" can be the direction from the housing toward the first optical component, while "outward" can be the direction from the first optical component toward the housing, that is, the opposite direction to "inward".

[0193] Figure 7 This is a view showing the first optical component of the light emitting section and the first lens holder according to an embodiment. Figure 8 This is a perspective view of the first lens holder of the light emitting section according to an embodiment, and Figure 9 This is a cross-sectional view of the first lens holder, housing, and drive coil of the light emitting section according to an embodiment.

[0194] Reference Figure 7 and Figure 8 The first optical component 120 of the light emitting section can be inserted into the lens receiving portion 131 of the first lens holder 130. As described above, the first optical component 120 can be composed of multiple lenses. In addition, the first optical component 120 may include threads on its outer surface. The first lens holder 130 may also have threaded grooves on its inner surface corresponding to the threads of the first optical component 120. Therefore, the first optical component 120 and the first lens holder 130 can be threadedly connected to each other.

[0195] In this embodiment, the first lens holder 130 may include not only the lens receiving portion 131 described above, but also magnet mounting grooves 132h1 to 132h4. Multiple magnet mounting grooves 132h1 to 132h4 may be provided. In this embodiment, four magnet mounting grooves are provided, and these magnet mounting grooves may be positioned on each outer surface of the first lens holder 130.

[0196] In this embodiment, the first lens holder 130 may include a first outer surface 132a and a second outer surface 132b opposite to each other, and a third outer surface 132c and a fourth outer surface 132d opposite to each other and located between the first outer surface 132a and the second outer surface 132b.

[0197] Additionally, the first outer surface 132a may face the side of the aforementioned housing, the second outer surface 132b may face the side of the aforementioned second housing, the third outer surface 132c may face the side of the aforementioned third housing, and the fourth outer surface 132d may face the side of the aforementioned fourth housing.

[0198] Additionally, the plurality of magnet mounting grooves may include a first magnet mounting groove 132h1 to a fourth magnet mounting groove 132h4. The first magnet mounting groove 132h1 may be positioned on a first outer surface 132a. The second magnet mounting groove 132h2 may be positioned on a second outer surface 132b. The third magnet mounting groove 132h3 may be positioned on a third outer surface 132c. The fourth magnet mounting groove 132h4 may be positioned on a fourth outer surface 132d.

[0199] The magnets of the drive magnet section, which will be described below, can be placed in each of the first magnet placement grooves 132h1 to the fourth magnet placement grooves 132h4.

[0200] Furthermore, the first magnet mounting groove 132h1 and the second magnet mounting groove 132h2 can face each other, and the third magnet mounting groove h3 and the fourth magnet mounting groove 132h4 can be positioned facing each other. Additionally, the first magnet mounting groove 132h1 to the fourth magnet mounting groove 132h4 can have the same shape. With this configuration, the electromagnetic force generated by the magnets mounted in the magnet mounting grooves is constantly generated upwards or downwards, allowing the first lens holder to move upwards or downwards in a balanced manner without tilting to one side.

[0201] According to an embodiment, the areas of the first magnet mounting groove 132h1 to the fourth magnet mounting groove 132h4 (on the plane XZ or YZ) can be reduced outwards. Furthermore, the length L1 of the outermost portion of the first magnet mounting groove 132h1 to the fourth magnet mounting groove 132h4 can be less than the length L2 of the innermost portion of the first magnet mounting groove 132h1 to the fourth magnet mounting groove 132h4. With this configuration, the phenomenon of each of the plurality of magnets separating from the first magnet mounting groove 132h1 to the fourth magnet mounting groove 132h4, as described below, can be suppressed. In other words, the connection force between the plurality of magnets and the plurality of magnet mounting grooves can be improved.

[0202] Furthermore, the first lens holder according to the embodiment may also include an injection hole eh positioned in the lower portion of the first magnet mounting groove 132h1 to the fourth magnet mounting groove 132h4. The injection hole eh may be positioned in the lower portion of the first magnet mounting groove 132h1 to the fourth magnet mounting groove 132h4. For example, the injection hole eh may be positioned at the bottom of the first magnet mounting groove 132h1 to the fourth magnet mounting groove 132h4. Additionally, the injection hole eh may be positioned to overlap with the first magnet mounting groove 132h1 to the fourth magnet mounting groove 132h4 in the third direction (Z-axis direction). Therefore, when the adhesive member is injected through the injection hole eh, the adhesive member can move between the magnet mounting groove and the magnet. In other words, through injection pressure and capillary action, the adhesive member can be distributed over the entire area between the magnet and the magnet mounting groove. Therefore, the connection force between the magnet and the magnet mounting groove can be further improved, thereby preventing the magnet from separating from the magnet mounting groove.

[0203] Furthermore, the lens barrel groove gr can be positioned between adjacent magnet mounting grooves among the first magnet mounting groove 132h1 to the fourth magnet mounting groove 132h4. According to an embodiment, the lens barrel groove gr can be positioned on the first virtual line VX1 and the second virtual line VX2. Additionally, the lens barrel groove gr can be bisected by the first virtual line VX1 and the second virtual line VX2.

[0204] In this embodiment, the first virtual line VX1 bisects the second magnet mounting groove 123h2 and the fourth magnet mounting groove 132h4, and also bisects the first magnet mounting groove 132h1 and the third magnet mounting groove 132h3. Similarly, the second virtual line VX2 bisects the first magnet mounting groove 132h1 and the fourth magnet mounting groove 132h4, and also bisects the third magnet mounting groove 132h3 and the second magnet mounting groove 132h2. Furthermore, the intersection of the first virtual line VX1 and the second virtual line VX2 can also be located on the aforementioned central axis HX of the housing hole.

[0205] The lens barrel recess gr can be positioned in the lower portion of the first lens holder 130. Therefore, due to the lens barrel recess gr, the first lens holder 130 can have a structure with an open lower edge. Therefore, the aforementioned mounting protrusion of the housing can be positioned in the lens barrel recess gr. Therefore, the first lens holder 130 can be supported by the mounting protrusion.

[0206] Reference Figure 9 The lens barrel groove gr can overlap with the mounting protrusion 115 of the housing 110 in the third direction (Z-axis direction). Therefore, even when the first lens holder 130 moves in the third direction (Z-axis direction), the first lens holder 130 can be blocked by the mounting protrusion 115 of the housing 110 and cannot move downward. Therefore, even when the first lens holder moves, collision between the control element positioned in the aforementioned hole and the first lens holder can be prevented. Therefore, the reliability of the component can be improved.

[0207] Figure 10 This is a view showing the driving magnet section and the driving coil section of the light emitting section according to an embodiment. Figure 11 This is a view used to describe the driving of the driving magnet section and the driving coil section of the light emitting section according to the embodiment. Figure 12 This is a top view of the driving magnet section, driving coil section, side substrate, and control element of the light emitting section according to an embodiment, and... Figure 13 This is a view used to describe the positional relationship between the drive coil portion and the drive magnet portion according to an embodiment.

[0208] Reference Figures 10 to 12 According to the embodiment, the driving unit may include a driving magnet unit 140 and a driving coil unit 150. The driving magnet unit 140 may include a plurality of magnets.

[0209] In this embodiment, the drive magnet section 140 may include a first magnet 141 to a fourth magnet 144. The first magnet 141 and the second magnet 142 may be positioned facing each other. For example, the first magnet 141 and the second magnet 142 may be arranged symmetrically with respect to a first direction (X-axis direction).

[0210] The third magnet 143 and the fourth magnet 144 can be positioned facing each other and positioned between the first magnet 141 and the second magnet 142. For example, the third magnet 143 and the fourth magnet 144 can be arranged symmetrically with respect to the second direction (Y-axis direction).

[0211] The first magnet 141 to the fourth magnet 144 can be located in the first magnet mounting groove to the fourth magnet mounting groove, respectively. The first magnet 141 to the fourth magnet 144 can be set to be spaced apart from each other by the same distance relative to the central axis HX. Therefore, the current flowing through the drive coil section 150 and the magnetic force can interact in a balanced manner, so that the first lens holder can be moved in a balanced manner by electromagnetic force without tilting to one side.

[0212] Furthermore, the first magnet 141 to the fourth magnet 144 can be unipolar magnetized in each magnet mounting groove. With this configuration, a balanced electromagnetic force can be generated solely by the drive coil section, and current flows through the drive coil section in a single direction.

[0213] Alternatively, the first magnet 141 to the fourth magnet 144 can be bipolar magnetized in each magnet mounting groove. In this case, contrary to what is described below, each coil corresponding to the first magnet 141 to the fourth magnet 144 can exist independently. In this case, the movement of the first lens holder can be controlled more precisely by controlling the amount of current flowing through each coil.

[0214] As described above, the drive coil section 150 can have a closed-loop shape in the XY plane. Therefore, the drive coil section 150 can surround the drive magnet section 140. In other words, since the drive coil section 150 has a closed-loop shape, the camera device can control each magnet of the drive magnet section 140 with a single current. This configuration prevents tilting upwards due to multiple magnets. Therefore, the upper surface of the first optical component can move in the opposite direction to the light receiving section (e.g., the opposite direction to the first direction), preventing the first optical component from tilting. Furthermore, the reduction in the efficiency of the input light to the light receiving section due to tilting can be suppressed.

[0215] The drive coil portion 150 can be mounted on the aforementioned coil mounting portion. Furthermore, the drive coil portion 150 can at least partially overlap with the drive magnet portion 140 in either the first direction (X-axis direction) or the second direction (Y-axis direction).

[0216] Furthermore, the drive coil portion 150 can be configured to surround the drive magnet portion 140. In other words, the drive magnet portion 140 can be positioned on the closed loop of the drive coil portion 150.

[0217] In addition, when current flows through the drive coil section 150, the first lens holder and the drive magnet section 140 can move along the third direction (Z-axis direction) by electromagnetic force.

[0218] For example, current can flow counterclockwise through the drive coil section 150. Additionally, the first magnet 141 to the fourth magnet 144 can generate an outward magnetic field. Based on this, the movement of the first lens holder caused by electromagnetic force will be described below.

[0219] At this time, the first magnet 141 generates a magnetic field B1 in the direction opposite to the second direction, and the current I1 flows through the drive coil section 150 in the region facing the first magnet 141 in the direction opposite to the first direction. Therefore, the magnetic field B1 and the current I1 generate an electromagnetic force F1 in the direction opposite to the third direction (Z-axis direction).

[0220] Furthermore, the second magnet 142 generates a magnetic field B2 in the second direction, and a current I2 flows through the drive coil section 150 in the first direction in the region facing the second magnet 142. Therefore, the magnetic field B2 and the current I2 generate an electromagnetic force F2 in the direction opposite to the third direction (Z-axis direction).

[0221] Furthermore, the third magnet 143 generates a magnetic field B3 in the direction opposite to the first direction, and a current I3 flows through the drive coil section 150 in the second direction in the region facing the third magnet 143. Therefore, the magnetic field B3 and the current I3 generate an electromagnetic force F3 in the direction opposite to the third direction (Z-axis direction).

[0222] Furthermore, the fourth magnet 144 generates a magnetic field B4 in the first direction, and a current I4 flows through the drive coil section 150 in the region facing the fourth magnet 144 in a direction opposite to the second direction. Therefore, the magnetic field B4 and the current I4 generate an electromagnetic force F4 in the direction opposite to the third direction (Z-axis direction). At this time, the first lens holder can move in the third direction (Z-axis direction) or upwards by the electromagnetic forces F1 to F4. For example, since the coil section of the coil is fixed to the housing, the electromagnetic forces F1 to F4 can act on the movable drive magnet. In other words, when electromagnetic forces F1 to F4 are generated in the direction opposite to the third direction (Z-axis direction), the drive magnet section 140 can move in the third direction (axial direction).

[0223] In addition, when current flows clockwise through the drive coil section 150, the first lens holder can move in the opposite direction to the third direction or downward.

[0224] Furthermore, the drive coil section 150 can be configured to be spaced apart from the drive magnet section 140 by a first separation distance dd1. The separation distance dd1 can be 70 μm to 90 μm. This configuration ensures ease of assembly and allows for easy control of the movement of the first lens holder according to the strength of the electromagnetic force. Moreover, when the separation distance dd1 is 90 μm, the electromagnetic force between the magnet and the coil can be 0.002 mN / mA.

[0225] Furthermore, one end of the drive coil section 150 can be connected to the first wire w1 and the second wire w2 for electrical connection with the side substrate 170. The first wire w1 and the second wire w2 are electrically connected to the side substrate 170, and specifically, are positioned at corresponding locations on the side substrate 170 to minimize resistance. Therefore, accuracy degradation due to resistance can be prevented and power efficiency can be improved.

[0226] In addition, the first wire w1 and the second wire w2 can be connected to one end and the other end of the drive coil section 150, which is composed of coils, respectively.

[0227] Therefore, based on the control signal received from the side substrate 170, a predetermined current is applied to the drive coil section 150 via the first wire w1 and the second wire w2, and the first lens holder can be moved by electromagnetic force due to the applied current, etc. Therefore, the drive stability can be improved by setting the side substrate 170 adjacent to the drive section of the light emitting section.

[0228] Furthermore, since rectifier elements (e.g., capacitors) are disposed on the side substrate 170, noise in the current supplied to the drive coil can be removed by the rectifier elements. Therefore, the first lens holder can be moved precisely. In addition, since the rectifier elements are not disposed on the main substrate, the size of the camera device can be easily reduced.

[0229] Additionally, the side substrate 170 may include terminal portions disposed below and electrically connected to the main substrate. The terminal portions can be electrically connected to the main substrate via soldering or similar means. This configuration allows for the transmission and reception of control signals (such as current) between the main substrate and the side substrate.

[0230] Furthermore, the control element SS can be mounted on the side substrate 170. The control element SS can be integrally formed with the side substrate. The control element SS can be located below the drive coil portion 150. For example, the control element SS can be disposed at the lower part of the lowest end of the drive coil portion 150. In addition, the control element SS can be positioned to at least partially overlap with the drive coil portion 150 in the third direction (Z-axis direction). Therefore, the control element SS can accurately sense the magnetic force intensity from the drive magnet portion 140 located within the drive coil portion 150. Furthermore, in the camera device according to the embodiment, the control element SS can calculate the position of the first lens module or provide a signal indicating the position by detecting the magnetic force generated from the drive magnet portion, without the need for a separate magnet. Therefore, the compactness of the light emitting portion can be easily achieved.

[0231] Furthermore, the control element SS and the drive magnet section (particularly the third magnet) can have a predetermined separation distance from each other. This separation distance can be from 0.44 mm to 0.66 mm. With this configuration, the magnetic force or detection value detected by the control element corresponding to the position of the first lens module can be linear. Therefore, the position detection accuracy of the control element can be improved.

[0232] Furthermore, the height T1 of the drive coil portion 150 in the third direction (Z-axis direction) can be less than the height T2 of each magnet or drive magnet portion in the third direction (Z-axis direction). With this configuration, even when the first lens holder and the drive magnet portion 140 move in the third direction (Z-axis direction), the drive coil portion 150 can be positioned to overlap with the drive magnet portion 140 in the first direction (X-axis direction) and the second direction (Y-axis direction).

[0233] Reference Figure 13 When the first lens holder is positioned at its lowest point (hereinafter referred to as "lowest drive"), the drive coil portion 150 and the drive magnet portion 140 may overlap in the direction of movement (i.e., in a direction perpendicular to a third direction (Z-axis direction) or a plane (XY)). Alternatively, in the lowest drive state, the upper surface of the drive coil portion 150 may be positioned at least below the upper surface of the drive magnet portion 140.

[0234] Furthermore, even when the first lens holder is at its uppermost position (hereinafter referred to as "maximum drive"), the drive coil portion 150 and the drive magnet portion 140 can overlap in the plane (XY). Alternatively, during maximum drive, the lower surface of the drive coil portion 150 can be positioned at least above the lower surface of the drive magnet portion 140.

[0235] In other words, even when the drive magnet section 140 moves (e.g., from the lowest drive to the highest drive), the drive coil section 150 according to this embodiment can overlap with the drive magnet section 140 in a direction perpendicular to the third direction (Z-axis direction).

[0236] Furthermore, the first center or first central axis Z1 that divides the drive coil section 150 into two equal parts in the third direction can be located in the first magnet region ZP1 of the drive magnet section 140.

[0237] In one embodiment, the driving magnet section 140 may include a first magnet region ZP1 and a second magnet region ZP2. The first magnet region ZP1 may be located above the second magnet region ZP2, and the second magnet region ZP2 may be located below the first magnet region ZP1. The first magnet region ZP1 and the second magnet region ZP2 may be divided relative to a second center or a second central axis Z2 that bisects the driving magnet section 140 in a third direction.

[0238] At this time, when driving from the lowest to the highest speed, the first central axis Z1 of the drive coil section 150 can be positioned on the first magnet region ZP1. With this configuration, the magnitude of the electromagnetic force generated between the drive section (i.e., the drive magnet section 140 and the drive coil section 150) can be increased when driving from the lowest to the highest speed.

[0239] Furthermore, the current applied to the drive coil during maximum drive can be greater than the current applied to the drive coil during minimum drive. However, according to the embodiment, the separation distance between the first central axis Z1 and the second central axis Z2 during maximum drive can be smaller than the separation distance between the first central axis Z1 and the second central axis Z2 during minimum drive. Therefore, energy efficiency can be improved by reducing the amount of current applied to the drive coil during maximum drive.

[0240] With this configuration, the overlapping area between the drive coil section 150 and the drive magnet section 140 in the XY plane can be constant. Therefore, the variation in the electromagnetic force generated by the drive coil section 150 and the drive magnet section 140 can be minimized depending on their positions (especially in the Z-axis direction). In other words, the drive or movement of the first lens holder caused by the electromagnetic force can be linearly related to the amount of change in current. In other words, the first lens holder can be moved precisely.

[0241] Furthermore, during the lowest driving mode, the area where the driving coil portion 150 overlaps with the first magnet region ZP1 in the direction perpendicular to the optical axis or a third direction (Z-axis direction) can be larger than the non-overlapping area. Additionally, during the highest driving mode, the area where the driving coil portion 150 overlaps with the first magnet region ZP1 in the direction perpendicular to the optical axis or a third direction (Z-axis direction) can be larger than the area where the driving coil portion 150 overlaps with the second magnet region ZP2 in the same direction. Furthermore, during the highest driving mode, the lowest portion of the driving coil portion 150 can be located above the lowest portion of the driving magnet portion 140.

[0242] Figure 14 This is a view showing one side of the side substrate of the light emitting section according to this embodiment. Figure 15 This is a view showing another side of the side substrate of the light emitting section according to an embodiment.

[0243] Reference Figure 14 and Figure 15 The side substrate 170 may have one side and another side, the other side being opposite to and in contact with the housing.

[0244] The side substrate 170 may include a first conductive portion EC1 and a second conductive portion EC2 on one side, which are connected to the first and second wires of the drive coil portion. Additionally, the side substrate 170 may include a connection hole 170a on the other side. As described above, the connection hole 170a can be connected to a connection protrusion of the housing. Therefore, the side substrate 170 can be connected to the side surface of the housing.

[0245] Alternatively, the control element SS may be located on the other side of the side substrate 170. The control element SS may be placed on the other side of the side substrate 170 and inserted into the hole.

[0246] Figure 16 This is a top view of the first lens holder, drive magnet, drive coil, housing, side substrate, and control element of the light emitting section according to the embodiment. Figure 17 It is along Figure 16 The sectional view taken by line Z-Z' in the middle. Figure 18 It is along Figure 16 The sectional view taken by line Q-Q' in the middle. Figure 19 It is along Figure 16 The cross-sectional view taken by line Y-Y' in the middle.

[0247] Reference Figures 16 to 19 In the housing 110 according to the embodiment, the hole 113 and the mounting groove 114h can overlap in the first direction (X-axis direction). In addition, as described above, the hole 113 and the mounting groove 114h can be positioned on the third housing side 110k3, which has the maximum minimum separation distance from the light receiving part in the housing.

[0248] Additionally, the side substrate 170 may include a first conductive portion and a second conductive portion disposed on its outer surface, and a control element SS disposed on its inner surface.

[0249] Additionally, the control element SS can be housed in the hole 113. Furthermore, the control element SS can at least partially overlap with the mounting groove 114h. Additionally, the control element SS can be positioned below the coil mounting portion 114, that is, below the drive coil portion 150.

[0250] Furthermore, according to the embodiment, the control element SS can at least partially overlap with the third magnet 143 facing the third housing side 110k3 in the first direction (X-axis direction). Additionally, since the mounting groove 114h is positioned between the control element SS and the third magnet 143, the control element SS can easily detect the magnetic force generated from the third magnet 143 due to the opening.

[0251] Furthermore, the control element SS can at least partially overlap with the drive coil portion 150 in the third direction (Z-axis direction) (OV). Therefore, when the connecting member EX (such as epoxy resin) is applied to the third housing side portion 110k3, the connecting member EX can be positioned on the upper surface SSa of the control element SS. Thus, the upper surface SSa of the control element SS and the upper surface of the hole 113 can be connected to each other by the connecting member. In other words, the positioning of the drive coil portion 150 can be guided along the coil mounting portion 114, and the positioning of the control element SS can be guided by the hole 113 and the mounting groove 114h. Therefore, the control element SS and the drive coil portion 150 can be precisely arranged at the designed position. Therefore, the camera device according to the embodiment can precisely adjust the form of the input light according to the distance.

[0252] Furthermore, the control element SS can be disposed below the drive coil section 150, and at least a portion of the aforementioned connecting member EX can be positioned between the control element SS and the drive coil section 150. In other words, the connecting member EX can at least partially overlap with the control element SS and the drive coil section 150 in a third-order direction. With this configuration, the connecting member EX can prevent the magnetic field generated from the drive coil section 150 from acting on the control element SS in the form of noise. Therefore, the position of the optical component can be accurately detected by the control element SS.

[0253] Furthermore, when the first optical component converts light into a point form, the third central axis Z3 of the control element SS can overlap with the drive magnet section 140 in a direction perpendicular to the third direction or the plane XY.

[0254] Furthermore, when the first optical component converts light into a planar form, the third central axis Z3 of the control element SS may not overlap with the drive magnet section 140 in a direction perpendicular to the third direction or in the plane XY.

[0255] Therefore, compared to the planar form, the separation distance between the drive magnet 140 and the control element SS is reduced in the point form, thus enabling precise detection of the position of the first optical component via the control element SS. Consequently, in the point form, by precisely detecting the position of the first optical component, eye-safe control (e.g., notification) can be easily performed via light.

[0256] Additionally, the housing 110 may include a stepped portion 110st positioned on its side. In other words, the stepped portion 110st may be positioned or formed on the side of the housing side of the housing 110. The stepped portion 110st may be positioned on the facing surface in the second direction (Y-axis direction) and on the side spaced apart from the light receiving portion. In other words, the outer surface of the housing 110 may have a groove due to the stepped portion 110st. In this embodiment, the stepped portion on the outer surface of the housing 110 may have an inwardly curved structure. Therefore, the outer surface of the housing 110 located in the stepped portion may be positioned inside the outer surface of the housing 110 in the region other than the stepped portion. With this configuration, the housing 110 can be mounted on the first base and easily connected to the first base, as will be described below. In addition, the stepped portion of the housing 110 may be disposed in a second groove, which will be described below. For example, the stepped portion of the housing 110 may be disposed in a 2-2 groove (corresponding to...). Figure 26 (G2b in the example). With this configuration, the stepped portion 110st or the 2-2 groove of the housing 110 can be used as an alignment mark. Therefore, the left-right asymmetry between the housing 110 and the base can be improved.

[0257] Figure 20 This is a view showing the first elastic member of the light emitting section according to an embodiment. Figure 21 This is a view showing the connecting member of the first elastic member of the light emitting section according to an embodiment. Additionally, Figure 22 This is a view showing the second elastic member of the light emitting section according to an embodiment, and Figure 23 This is a view showing the connecting member of the second elastic member of the light emitting section according to an embodiment.

[0258] Reference Figures 20 to 23 The elastic portion 160 may include a first elastic member 161 and a second elastic member 162. The elastic portion 160 may be located above or below the first lens holder 130 and is connected to the housing 110 and the first lens holder 130. Therefore, even when the first lens holder 130 is moved vertically by the drive unit, a preload can be applied to the vertical movement of the first lens holder 130 through the elastic portion 160 connected to the housing 110. Thus, when no current is applied to the drive coil, the first lens holder 130 can remain at the same position in the housing 110 due to the restoring force of the elastic portion 160.

[0259] The first elastic member 161 can be positioned above the first lens holder 130. The second elastic member 162 is positioned below the first lens holder 130.

[0260] The first elastic member 161 may include a first elastic connecting portion P1 and a second elastic connecting portion P2. The first elastic connecting portion P1 may be positioned outside the second elastic connecting portion P2. Furthermore, the first elastic connecting portion P1 may be connected to a protrusion of the housing 110. Additionally, the second elastic connecting portion P2 may be connected to the first lens holder 130. In this case, the aforementioned connecting member for connection may be applied to the first elastic connecting portion P1 and the second elastic connecting portion P2 (DA1). The connecting member may include epoxy resin, etc. Alternatively, the connecting member may also be, for example, a damping liquid. Furthermore, the first elastic connecting portion P1 and the second elastic connecting portion P2 may also include additional grooves extending to one side, thereby facilitating the application of the connecting member.

[0261] Furthermore, the first patterned portion PT1, which has various curved sections, can be located between the first elastic connecting portion P1 and the second elastic connecting portion P2. In other words, the first elastic connecting portion P1 and the second elastic connecting portion P2 can be connected to each other through the first patterned portion PT1 located between them.

[0262] Furthermore, the first elastic connecting part P1 and the second elastic connecting part P2 may have a hole or groove shape, and their shapes have assembly tolerances with the housing or the first lens holder to be connected.

[0263] Furthermore, the first patterned portion PT1 can be symmetrically arranged about either the first diagonal DL1 or the second diagonal DL2. The first diagonal DL1 can be a line connecting the contact point between the first housing side and the fourth housing side, and the contact point between the second housing side and the third housing side. Similarly, the second diagonal DL2 can be a line connecting the contact point between the housing side and the third housing side, and the contact point between the second housing side and the fourth housing side.

[0264] Additionally, a damping member can be applied to the first patterned portion PT1. The damping member may include a damping fluid. Vibration generated by the elastic portion can be suppressed by the damping fluid. The damping member can be applied to the first patterned portion PT1. Furthermore, the damping member can be spaced apart from the housing. Therefore, vibrations generated from the first patterned portion PT1 can be reduced, and malfunctions due to the connection between the housing and the spring can be prevented. More specifically, the damping member can be applied to the region of the first patterned portion PT1 (DP) adjacent to the first elastic connection portion P1 or the second elastic connection portion P2. Therefore, by connecting the first patterned portion PT1 to the first elastic connection portion P1 and the second elastic connection portion P2, which have low vibration, vibration suppression can be improved.

[0265] Furthermore, the aforementioned first elastic connecting portion P1 and second elastic connecting portion P2 can be located on the first diagonal DL1 or the second diagonal DL2. With this configuration, even when the connecting member is applied to the first elastic connecting portion P1 and the second elastic connecting portion P2, it is possible to prevent the connecting member from being applied to the magnet or the first optical component 120. Therefore, it is possible to prevent the first elastic member 161 from being connected to any component other than the housing 110 or the first lens holder 130, thereby allowing the preload to be applied uniformly between the housing and the first lens component. Therefore, the vertical movement of the first lens holder can be performed linearly (i.e., precisely) according to control.

[0266] In addition, when the first lens holder 130 moves up and down, that is, moves along the third direction (Z-axis direction), the first elastic connecting part P1 and the second elastic connecting part P2 on the first diagonal DL1 and the second diagonal DL2 can suppress tilting or movement based on the first direction (X-axis direction) or the second direction (Y-axis direction).

[0267] The first patterned portion PT1 can be designed to have an elastic modulus of the first elastic member 161, which linearly corresponds to the vertical movement distance of the first lens holder and the electromagnetic force. Furthermore, as described below, the first elastic member 161 and the second elastic member 162 can be disposed above and below the first lens holder, thereby minimizing the influence of momentum on the vertical movement of the first lens holder 130.

[0268] Furthermore, the first elastic member 161 can have a shape in which the safety factor of the elastic member is greater than or equal to a threshold, such that the shape will not deform due to impact or the like. In other words, the safety factor of the first elastic member relative to the first direction or the second direction can be greater than the safety factor of the first elastic member relative to a third direction. Therefore, the durability against impacts applied in the first direction or the second direction can be increased.

[0269] Similarly, the second elastic member 162 may include a third elastic connecting portion P3 and a fourth elastic connecting portion P4. The third elastic connecting portion P3 may be positioned outside the fourth elastic connecting portion P4.

[0270] Additionally, the third elastic connecting part P3 can be connected to the protrusion of the housing 110. Furthermore, the fourth elastic connecting part P4 can be connected to the first lens holder 130. In this case, connecting members can also be applied to the third elastic connecting part P3 and the fourth elastic connecting part P4 to achieve the aforementioned connection (DA2).

[0271] The connecting member may include epoxy resin, etc. Alternatively, the connecting member may also be, for example, a damping fluid. Furthermore, the third elastic connecting part P3 and the fourth elastic connecting part P4 may also include additional grooves extending to one side, thereby facilitating the application of the connecting member.

[0272] Furthermore, the second patterned portion PT2, which has various curved sections, can be positioned between the third elastic connecting portion P3 and the fourth elastic connecting portion P4. In other words, the third elastic connecting portion P3 and the fourth elastic connecting portion P4 can be connected to each other through the second patterned portion PT2 located between them.

[0273] Furthermore, the third elastic connecting part P3 and the fourth elastic connecting part P4 may have a hole or groove shape, and their shapes have assembly tolerances with the housing or the first lens holder to be connected.

[0274] Furthermore, the second pattern section PT2 can be symmetrically arranged about either the third diagonal DL3 or the fourth diagonal DL4. The third diagonal DL3 can be a line connecting the contact point between the first housing side and the fourth housing side, and the contact point between the second housing side and the third housing side. Similarly, the fourth diagonal DL4 can be a line connecting the contact point between the housing side and the third housing side, and the contact point between the second housing side and the fourth housing side.

[0275] Additionally, a damping component can be applied to the second patterned section PT2. The damping component may include a damping fluid. The damping fluid can suppress vibrations generated by the elastic section. The damping component can be applied to the second patterned section PT2.

[0276] Furthermore, the aforementioned third elastic connecting portion P3 and fourth elastic connecting portion P4 can also be located on the third diagonal DL3 or the fourth diagonal DL4. With this configuration, even when the connecting member is applied to the third elastic connecting portion P3 and the fourth elastic connecting portion P4, it is possible to prevent the connecting member from being applied to the magnet or the first optical component 120. Therefore, it is possible to prevent the second elastic member 162 from being connected to any component other than the housing 110 or the first lens holder 130, thereby allowing the preload to be applied uniformly between the housing and the first lens component. Therefore, the vertical movement of the first lens holder is linearly executed according to this control, thereby enabling precise vertical movement control.

[0277] In addition, when the first lens holder 130 moves up and down (i.e., along the third direction (Z-axis direction)), the first elastic connecting part P1 and the fourth elastic connecting part P4 on the third diagonal DL3 and the fourth diagonal DL4 can suppress the tilting or movement of the first lens holder 130 based on the first direction (X-axis direction) or the second direction (Y-axis direction).

[0278] The second patterned portion PT2 can be designed to have an elastic modulus of the second elastic member 162, which linearly corresponds to the vertical movement distance of the first lens holder and the electromagnetic force. Furthermore, as described below, the first elastic member 161 and the second elastic member 162 can be disposed above and below the first lens holder, thereby minimizing the influence of momentum on the vertical movement of the first lens holder 130.

[0279] Furthermore, the second elastic member 162 can have a shape such that its safety factor is greater than or equal to a threshold, preventing deformation due to impact. In other words, the safety factor of the second elastic member relative to the first or second direction can be greater than the safety factor of the second elastic member relative to a third direction. Therefore, durability against impacts applied in the first or second direction can be increased.

[0280] Figure 24 This is a view showing the base of the camera module according to an embodiment. Figure 25 This is a view showing the second optical component and the second lens barrel of the light receiving section according to an embodiment, and Figure 26 This is a view showing the cover of the camera module according to an embodiment.

[0281] Reference Figure 24 The base 200 can be positioned on the main substrate 4 and can contact the main substrate 4. In addition, the first lens holder, the first optical component, the second lens barrel, the second optical component and the housing as described above can be mounted on the base 200.

[0282] The base 200 may include a first base 210 and a second base 220 spaced apart from each other. The first base 210 and the second base 220 may be spaced apart from each other in a first direction (X-axis direction). The first base 210 and the second base 220 may be integrally formed. Alternatively, the first base 210 and the second base 220 may have separate structures. In this embodiment, as will be described below, the first base 210 and the second base 220 are integrally formed with each other, thus increasing the rigidity of the base 200 and improving the reliability of the camera device.

[0283] The housing (or a component of the light emitting part, such as the first optical component or the first lens holder) may be mounted on the first base 210. In other words, the first base 210 may accommodate the housing (or a component of the light emitting part, such as the first optical component or the first lens holder).

[0284] Additionally, the second base 220 can be disposed adjacent to the first base 210, allowing the second optical component and the second lens barrel to be mounted thereon. The image sensor can be located below the second base 220.

[0285] The first base 210 and the second base 220 may each include base holes 210a and 220a. Light signals from a light source can be output toward the object through the base holes 210a and 220a, and light signals reflected from the object (reflected light) can be provided to an image sensor. For example, a light signal can be output toward the object through the first base hole 210a, and a light signal reflected through the second base hole 220a can be provided to an image sensor.

[0286] Furthermore, the aforementioned filter can be disposed on each of the first base 210 and the second base 220. Additionally, although the first base 210 and the second base 220 are shown as an integral unit, they can be separate. Furthermore, the first base 210 and the second base 220 can have separate structures.

[0287] In the camera device according to the embodiment, the light receiving unit 2 may also have a structure separate from the light emitting unit 1. Therefore, in the camera device, the main substrate may also be divided into a first substrate and a second substrate, a first base may be mounted on the first substrate, and a second base may be mounted on the second substrate. Additionally, the camera device may include a housing and a light emitting unit, the housing being connected to the base, and the light emitting unit including optical components disposed within the housing. In this case, the camera device may include a first cover. As detailed configurations of each component, the same configurations described above or as described below may be applied. Furthermore, the first cover may correspond to the cover described later, and the cover may also have a structure divided into a first cover on a first base and a second cover on a second base. In other words, the ranging camera device may include a light emitting unit comprising a first substrate, a first base disposed on the first substrate, a housing connected to the first base, and optical components disposed within the housing.

[0288] Furthermore, in the rangefinder camera device, the light receiving unit may include a second substrate separate from the first substrate, an image sensor disposed on the second substrate, and a second base disposed on the second substrate and separate from the first base. Additionally, the light receiving unit may also include a second cover.

[0289] Alternatively, the ranging camera device may include a single substrate or an integral substrate, without separating the first and second substrates. Alternatively, the separate first and second base portions may be mounted on the integral substrate. Furthermore, the camera device may have only a second cover without a first cover, or only a first cover without a second cover.

[0290] As described above, in a rangefinder camera device, the main substrate, base, and cover can be formed as separate structures or as a single unit. When separated, each of the main substrate, base, and cover can correspond to a component of the light emitting part and the light receiving part.

[0291] In addition, as described above, the second base 220 can be tilted, and the filter attached to the second base 220 can also be tilted, so that the camera device according to the embodiment can perform super-resolution technology.

[0292] More specifically, the first base 210 according to the embodiment may include a body and a sidewall having a cavity therein.

[0293] The body can be located below the first base 210. Therefore, the body can contact the main substrate. In other words, the body can be supported by the main substrate. In addition, the body can be used interchangeably with the "bottom", and the bottom surface of the first base 210 can be the bottom or the upper surface of the body.

[0294] The sidewall can be disposed along the edge of the body at the upper part of the body. In other words, the sidewall can be disposed at the bottom or bottom surface of the first base 210.

[0295] In this embodiment, the sidewall may have an internal cavity, and the housing (or components of the light emitting part, such as the first optical component and the first lens holder) may be disposed in the cavity as described above.

[0296] Furthermore, the first bonding member, which will be described below, can be disposed between the bottom, which serves as the body, and the housing 110. Additionally, the first bonding member can be disposed between the bottom (which serves as the body) and the housing 110. Therefore, the first bonding member can contact the body or the bottom and the lower surface of the housing to connect the base and the housing.

[0297] Additionally, the second joining member can be spaced apart from the first joining member in the optical axis direction and disposed between the sidewall and the housing in the first base. For example, the first joining member can be positioned inside the second joining member. Alternatively, the second joining member can be positioned above the first joining member.

[0298] Furthermore, a second connecting member can be disposed between the stepped portion of the housing and the sidewall of the base. Therefore, the second connecting member can contact the stepped portion of the housing and the sidewall of the base, connecting the stepped portion and the sidewall. In other words, the second connecting member can connect the housing and the base to each other, increasing the connection force between the housing and the base.

[0299] Reference Figure 25 The second optical component 310 can be connected to the second lens barrel 320. The second optical component 310 can be inserted into a hole located at the center of the second lens barrel 320. In addition, the second lens barrel 320 can be threadedly connected to the second base 220 of the base 200 by having threads on its outer surface.

[0300] The second optical component 310 may also consist of multiple lenses. The second optical component 310 may have the same structure as the first optical component or optical component described above.

[0301] Reference Figure 26 In addition to the above description, cover 400 may also include a first cover portion 410 and a second cover portion 420. The first cover portion 410 may include a first cover hole 410a, which is positioned on a first base part and overlaps with a first optical component. Light signals (output light) passing through the first optical component via the first cover hole 410a can illuminate an object.

[0302] The second cover portion 420 may include a second cover hole 420a, which is positioned on the second base portion and overlaps with the second optical component. Light signals (reflected light) passing through the second optical component via the second cover hole 420a can illuminate the image sensor.

[0303] Figure 27 This is a view used to illustrate the movement of the first optical component in the light emitting section according to an embodiment. Figure 28 It is a view used to describe the form of light signals based on the movement of the first optical component, and Figure 29 This is an example view showing an image of a light-receiving section that moves according to the first optical component.

[0304] Reference Figures 27 to 29 As described above, by moving the first optical component according to the embodiment in the vertical direction, the optical signal (output light) can be converted into a surface light source or a point light source. At this time, as the first lens holder moves along the optical axis or in the vertical direction, the first optical component housed in the first lens holder can also move together in the vertical direction. The movement of the first optical component will be described below.

[0305] The first optical component can be moved along the optical axis (parallel to the Z-axis) from a first position (or a first height, H1) to a second position (or a second height, H2). In the camera device according to the embodiment, when the first optical component is positioned in the region between the first position (or the first height, H1) and the second position (or the second height, H2), the light source can emit light.

[0306] At this time, the first position or first height H1 refers to the position or height when the first optical component 120 is moved to its lowest position by the drive unit. For example, the first height H1 is the height of the first optical component 120 when it is set at its lowest height.

[0307] The second position or second height H2 refers to the position or height when the first optical component 120 is moved to its uppermost position by the drive unit. For example, the second height H2 is the height when the first optical component 120 is set at its highest height.

[0308] Furthermore, in the camera device according to the embodiment, the first optical component 120 can be moved from an initial position to a region between a first height H1 and a second height H2. Additionally, the initial position can be located between the first height H1 and the second height H2. In this case, the camera device can reduce the energy consumption required to move from the initial position to the position or height used for light emission. In other words, energy efficiency can be improved.

[0309] Alternatively, the initial position in the camera device can be located below the first position (or first height, H1). Therefore, the camera device according to the embodiment can output light from the light source LS in the form of a point light source or a dot pattern. Thus, since users typically perform ranging on objects located at a distance, the camera device can reduce energy efficiency and perform ranging quickly.

[0310] Furthermore, in this specification, when the first optical component is positioned at a first height from the substrate, this corresponds to the aforementioned first position. Additionally, when the first optical component is positioned at a second height from the substrate, this corresponds to the aforementioned second position. The second height may be greater than the first height.

[0311] Depending on the distance between the light source and the first lens module (or the first optical component (hereinafter referred to as "optical component")), the output light can be output in a planar pattern or in a multi-point form. Therefore, when the first optical component 120 is positioned at the first height H1, the output light illuminates the object in a point form, while when the first optical component 120 is positioned at the second height H2, the output light can illuminate the object in a planar form.

[0312] In this embodiment, the drive unit can move the first optical component 120 in the optical axis direction (Z-axis direction). Furthermore, as described above, the amount of upward movement of the first optical component 120 can be adjusted according to the amount of current flowing through the drive coil unit.

[0313] For example, in the camera device according to the embodiment, the first optical component 120 can be moved to reduce the distance from the light source LS from a maximum (second height, see...) to a maximum. Figure 27 (a)) to the minimum (first height, see Figure 27 (b)).

[0314] Specifically, the aforementioned distance between the light source and the optical component (first optical component) can be the distance between the uppermost surface of the opening of the light source and the lowermost surface of the optical component. Furthermore, when the distance between the uppermost surface of the opening of the light source and the lowermost surface of the optical component is less than or equal to a predetermined distance, the light is output in a point form. Conversely, when the distance between the uppermost surface of the opening of the light source and the lowermost surface of the optical component is greater than or equal to a predetermined distance, the light source can output in a planar form.

[0315] The controller described below can control the amount of current supplied to the drive coil to adjust the distance between the first lens module (or the first optical component) and the light source, and ultimately control the form of the output light (surface light source or point light source). For example, when the amount of current supplied to the drive coil changes (e.g., the current value increases / decreases), the controller can change the amount of movement of the first lens module caused by the actuator.

[0316] In this embodiment, when the distance between the light source and the first lens module (or the first optical component) is greater than or equal to, or less than or equal to, a certain distance, an optical signal (output light) can be output in the form of a surface light source or a planar form, such as... Figure 28 (a) and Figure 29 As shown in (a). In other words, when the distance between the light source and the first lens module (or the first optical component) is between a preset distance (or a certain distance) and a maximum distance, the optical signal (output light) can be output in the form of a surface light source or a planar form. Here, the maximum distance is the distance (second height) when the distance between the light source and the movable first lens module is at its maximum, and can be the height of the first lens module and the distance to the light source when the actuator is driven to its maximum extent (e.g., maximum current).

[0317] On the other hand, when the distance between the light source and the first lens module (or the first optical component) is less than or equal to a certain distance, the light signal can be output in the form of a point light source or in a point form, such as... Figure 28 (b) and Figure 29 As shown in (b). In other words, when the distance between the light source and the first lens module (or the first optical component) is between a preset distance (or a certain distance) and a minimum distance, the light signal can be output in the form of a point light source or a point. Here, the minimum distance is the distance (first height) when the distance between the light source and the movable first lens module (or the first optical component) is minimized, or it can be the distance between the position of the first lens module (initial position) and the light source when the actuator is not driven.

[0318] In addition, as mentioned above, within a predetermined distance or smaller range, the light signal (output light) from the light source can be output in point form, and higher energy can be applied to the object.

[0319] The camera device according to this embodiment of the invention offers the advantage of being able to flexibly respond to the needs of various applications by changing the light pattern of the output light from a surface light source to a point light source, or by changing the resolution of the point light source according to the resolution of the output light, the distance from the object, the degree of power consumption, etc.

[0320] Figure 30This is a configuration diagram of a camera device according to an embodiment, and is a view used to describe light reflection in the camera device. Figure 31 This is a cross-sectional view of a camera device according to an embodiment. Figure 32 It is based on a cross-sectional view of an example camera device. Figure 33 It is based on a cross-sectional view of another example of a camera device, and Figure 34 This is a view showing the light source and output values ​​in a camera device according to an embodiment.

[0321] Reference Figure 30 and Figure 31 The camera device 10 according to the embodiment may include a substrate 4, a light source LS, a first lens holder 130, a first optical component 120, a driving unit, a photodetector PD, and a controller CP. Except as described below, the above can be applied in the same manner to the substrate 4, the light source LS, the first lens holder 130, the first optical component 120, the driving unit, the photodetector PD, and the controller CP.

[0322] In the camera device 10, as described above, the controller CP may include: a light controller configured to control the current supplied to the light source; a motion controller configured to control the current supplied to the drive unit; and a detection unit configured to detect abnormal states of the optical components.

[0323] A light controller can regulate the light power output from a light source by adjusting the power (e.g., current) applied to the light source.

[0324] The movement controller can adjust the current supplied to the coil of the drive unit. Through this control, the first optical component 120 can be moved from a first height to a second height.

[0325] Furthermore, in the camera device 10, the light emitted by the light source LS can be reflected by the first optical component 120, the first lens holder 130, the filter F, etc., and provided to the photodetector PD. Additionally, the photodetector PD can provide the detected value of the received light as an output value. For example, the photodetector PD can output a voltage or similar value as an output value.

[0326] The detection unit can detect abnormal conditions of the first optical component using the output value of the aforementioned photodetector. Abnormal conditions according to the embodiment may include damage (e.g., breakage), separation, or overcurrent of the optical component. Accordingly, the controller can detect abnormal conditions of the first optical component in the detection unit and adjust the light power output from the light source via the light controller.

[0327] In the camera device 10 according to the embodiment, as described above, the light source LS can be disposed on the substrate 4, and the light source LS and the first optical element 120 can overlap each other along the optical axis. For example, the center of the light source LS and the center of the first optical element 120 can be the same. In addition, the photodetector PD can be configured to be spaced apart from the light source in a direction perpendicular to the optical axis.

[0328] In this embodiment, in the camera device, the light source LS, the photodetector PD, and the driving unit can also be arranged sequentially in a direction perpendicular to the optical axis. The driving unit may include a controller CP.

[0329] For example, the light source LS can be completely overlapped with the first optical component 120 along the optical axis. Similarly, the photodetector PD can also be overlapped with the first optical component 120 along the optical axis. With this configuration, the photodetector PD can more easily detect light reflected from the first optical component 120, etc. For example, compared to the case where the photodetector is located outside the first optical component, the output value from the photodetector can be increased. In other words, the discrimination power of light detection in the photodetector can be improved.

[0330] In addition, the light source LS and the photodetector PD can overlap with the filter F along the optical axis. Therefore, the filter F can protect the light source LS and the photodetector PD from the influence of foreign objects.

[0331] Additionally, refer to Figure 32 and Figure 33 In a camera device 10 according to an example, the light source LS may overlap with the first optical component 12 along the optical axis.

[0332] Furthermore, the photodetector PD can be configured to be spaced apart from the light source LS in a direction perpendicular to the optical axis. Additionally, the photodetector PD can at least partially overlap with the first optical component 120 along the optical axis. Furthermore, the photodetector PD can overlap with the filter F along the optical axis. This configuration improves the sensitivity of the photodetector PD to light reflected from the first optical component 120 from the light emitted from the light source LS. In other words, the photodetector PD can receive light reflected from the first optical component 120 at high speed.

[0333] Reference Figure 33 In a camera device according to another example, the light source LS may overlap with the first optical component 120 along the optical axis, and the photodetector PD may be configured to be spaced apart from the light source LS in a direction perpendicular to the optical axis.

[0334] Furthermore, the photodetector PD may partially overlap with or not overlap with the first optical component 120 along the optical axis. For example, the photodetector PD may not be positioned in the region where it overlaps with the first optical component 120 along the optical axis. Additionally, the light source LS may overlap with the filter F along the optical axis, but the photodetector PD may partially overlap with or not overlap with the filter F along the optical axis.

[0335] With this configuration, most of the light reflected by the first optical element 120 from the upward-emitting light source LS can be received by the photodetector PD. In other words, light reflected only from the first optical element 120 can be intensively provided to the photodetector PD. Therefore, the accuracy of detecting abnormal states of the first optical element 120 can be improved.

[0336] Furthermore, in the camera device according to the embodiment, the light source LS, the photodetector PD, and the first optical component 120 can be set at a predetermined angle.

[0337] For example, in camera device 10, the first line VL1 and the second line VL2 can form a first angle θ. Here, the first line VL1 is the line connecting the intersection point AP1 between the photodetector PD and the optical axis OX and the lowermost surface of the first optical component 120. The second line VL2 is the line connecting the intersection point AP2 between the photodetector PD and the optical axis OX and the uppermost surface of the light source LS. In this case, the first angle can be between 10 degrees and 80 degrees.

[0338] The portion where the first line VL1 connects to the photodetector PD can be the central region of the photodetector PD. Similarly, the portion where the second line VL2 connects to the photodetector PD can also be the central region of the photodetector PD. For example, this portion could be the center of the upper surface of the photodetector PD.

[0339] Furthermore, in the camera device, the first angle θ can vary depending on the movement of the first optical component 120. For example, the first angle θ can vary from a second angle to a third angle. Here, the second angle can represent the first angle when the first optical component 120 is positioned at a first height, and the third angle can represent the first angle when the first optical component 120 is positioned at a second height. In this embodiment, the second angle can be smaller than the third angle. In other words, as the first optical component 120 moves away from the substrate 4, the first angle θ can decrease.

[0340] like Figure 34 As shown, in the camera device according to the embodiment, when the light power output from the light source LS increases, the light detection (i.e., output sensitivity) of the photodetector PD increases. Conversely, in the camera device according to the embodiment, when the light power output from the light source increases, the light detection (i.e., output value) of the photodetector also increases.

[0341] Figure 35 This is a view used to describe the movement of a first optical component in a camera device according to an embodiment. Figure 36 It is a view that shows the output values ​​based on the movement of the camera device.

[0342] Reference Figure 35 and Figure 36 In the camera device according to the embodiment, the photodetector PD can provide different output values ​​depending on the position of the first optical component 120. For example, as the first optical component 120 moves from a first height to a second height, the photodetector PD can output different output values.

[0343] For example, the output value of the photodetector PD may decrease as the first optical component 120 moves upward along the optical axis. In other words, the amount of light received by the photodetector PD may decrease.

[0344] In this embodiment, in the camera device, the photodetector PD can output a first output value for light received from the first optical component 120 located at a first height. Additionally, the photodetector PD can output a second output value for light received from the first optical component 120 located at a second height.

[0345] Furthermore, when the first optical component 120 is adjacent to the light source LS, the light reflected from the first optical component 120 can be provided to the photodetector PD, and the number of reflections and the amount of absorption can be reduced. Therefore, the photodetector PD can provide a high output value. For example, the first output value can be greater than the second output value.

[0346] Here, the light source LS can output light to the first optical component located at both the first and second heights with the same optical power. For example, since the power applied by the light controller is the same, the optical power of the light emitted from the light source LS can be provided equally regardless of the height of the first optical component 120. Therefore, when the optical power of the light source LS is the same, the output value of the photodetector can change in response to the movement of the first optical component 120. In particular, the output value decreases when the height of the first optical component 120 from the substrate increases. In this case, the output value can increase linearly or non-linearly in response to the height of the first optical component 120.

[0347] Furthermore, even when the light source LS outputs the same optical power, the output value of the photodetector in the case of an output surface light source may be less than the output value of the photodetector in the case of an output light with a dot pattern.

[0348] Furthermore, in the camera device according to the embodiment, as described above, the controller can use the output value of the photodetector PD to detect abnormal states of the first optical component 120 or the light source LS. Additionally, the controller can control the first optical component 120 or the light source LS based on the detected abnormal state of the first optical component 120.

[0349] In addition, the controller can detect abnormal states by comparing the first output value detected by the detection unit with a critical range. Specifically, it can detect either overcurrent or any of the abnormalities (e.g., damage) and separation of the first optical component.

[0350] For example, the controller can detect an abnormal state if the first output value of the photodetector PD is greater than the critical range of the photodetector PD, or if the second output value of the photodetector PD is less than the critical range of the photodetector PD.

[0351] Figures 37 to 39 This illustrates the case where the first output value exceeds the critical range of the photodetector PD. Figure 40 and Figure 41 The case where the second output value is less than the critical range of the photodetector PD is shown, and it will be described below.

[0352] Figure 37 This is a view showing an abnormal state of the first optical component of the camera device according to an embodiment. Figure 38 This is a view showing the output values ​​of the camera device's movement when an overcurrent occurs in the camera device according to an embodiment. Figure 39 This is a view showing the output values ​​of the camera device's movement when the first optical component in the camera device according to an embodiment is damaged.

[0353] Reference Figure 37 When there is an abnormality in the first optical component or the light source LS (abnormal state), the light supplied to the photodetector PD may increase. For example, when the first optical component 120 is broken or an overcurrent is applied to the light source LS, the output value of the photodetector may increase. In other words, as shown in the figure, when an overcurrent is applied to the first optical component (normal lens (overcurrent)), the first output value (overcurrent) may be greater than the first output value (normal). Similarly, the second output value (overcurrent) may be greater than the second output value (normal).

[0354] Furthermore, the first output value (broken) of a broken lens can be greater than the first output value (normal) of a normal lens. Similarly, the second output value (broken) of a broken lens can be greater than the second output value (normal) of a normal lens.

[0355] For example, when the first output value exceeds a critical range, the controller can detect either overcurrent or a malfunction (breakage) of the first optical component as an abnormal state. In other words, the controller can use light received from the first optical component 120 at a first height to detect the abnormal state as either overcurrent or a malfunction (breakage) of the first optical component. Furthermore, in response, the controller can provide eye safety for humans and others by adjusting the light power illuminating the object.

[0356] Reference Figure 38 and Figure 39 When the first output value of the photodetector exceeds a critical range, the controller can detect an abnormal state by either overcurrent or an malfunction of the first optical component. In the following views, the first output value during overcurrent is represented as "First Output Value (Overcurrent)", the second output value during overcurrent is represented as "Second Output Value (Overcurrent)", the first output value used for normal drive or lens is displayed as "First Output Value (Normal)", and the second output value used for normal drive or lens is displayed as "Second Output Value (Normal)". Furthermore, the first output value used for a broken lens is represented as "First Output Value (Broken)", and the second output value used for a broken lens is represented as "Second Output Value (Broken)".

[0357] Additionally, the controller can use the slope between the first and second output values ​​from the photodetector to detect or determine whether the abnormal condition is an overcurrent or an abnormality of the first optical component (e.g., breakage).

[0358] like Figure 38 As shown, during an overcurrent event, the output values ​​(first output value (overcurrent) and second output value (overcurrent)) from the photodetector tend to increase, and the output values ​​decrease as the height of the first optical component increases. Therefore, in a camera device, when the slope between the first and second output values ​​is positive, the controller can detect this as an abnormal state. Specifically, when the slope between the first and second output values ​​is within a predetermined value (e.g., a critical slope), the controller can detect the abnormal state as an overcurrent.

[0359] Furthermore, when the first optical component is positioned at different locations between the first and second heights, in addition to the first and second output values, the controller can compare the output value of the photodetector with the slope of another predetermined value corresponding to the slope. Therefore, the camera device can more easily and accurately detect overcurrent as an abnormal condition.

[0360] Additionally, when an overcurrent is detected, the controller can perform eye safety by reducing or blocking the current applied to the light source. Furthermore, in this specification, as the output value of the photodetector increases, the light illuminating the object decreases, and as the output value of the photodetector decreases, the light illuminating the object increases.

[0361] like Figure 39 As shown, when an abnormality (e.g., breakage) occurs in the first optical unit under abnormal conditions, the output values ​​(first output value (breakage) and second output value (breakage)) from the photodetector can increase. For example, when an abnormality (breakage) exists in a lens (hereinafter referred to as a "broken lens"), diffuse reflection increases due to the inhomogeneous shape caused by the breakage, and therefore the reflectivity can increase compared to when there is no abnormality (hereinafter referred to as a "normal lens"). Conversely, the transmittance in a normal lens can be higher than that in a broken lens.

[0362] Furthermore, the output value of the photodetector will vary depending on whether the lens is abnormal. For example, the first output value for a broken lens may be greater than the first output value for a normal lens. Therefore, in the camera device according to the embodiment, when the first output value is greater than a critical range, as described above, the controller can determine that the first optical component is abnormal or has an overcurrent.

[0363] In addition, in the event of an abnormality in the first optical component, the output value of the photodetector can also change in response to changes in the light power of the light source, just like a normal lens.

[0364] Alternatively, the slope between the first and second output values ​​from the photodetector may differ from the slope at each of the normal and broken lenses. Furthermore, in the case of both the broken and normal lenses, the output value of the photodetector may also change differently when the first optical component moves upward (to the second position).

[0365] In this embodiment, when the slope between the first output value and the second output value deviates from a predetermined value, the controller can detect the abnormal state as an malfunction (breakage) of the optical component. Furthermore, in the case of a broken lens, the slope between the first output value and the second output value may differ. For example, the sign of the slope between the first output value and the second output value may be positive. Alternatively, in the case of a normal lens, the slope or change between the first output value and the second output value may be negative (it may decrease).

[0366] As described above, the controller can use the slope or change between the first output value and the second output value to detect abnormal conditions of the first optical component.

[0367] Alternatively, the slope or variation between the first and second output values ​​for a broken lens (hereinafter referred to as the "breakage slope") may be greater than the slope or variation between the first and second output values ​​for a normal lens (hereinafter referred to as the "normal slope"). For example, the breakage slope may not be within a predetermined ratio of the normal slope.

[0368] Therefore, the controller can adjust the power applied to the light source so that the first output value falls within a critical range. For example, the controller can reduce the power (e.g., current) applied to the light source so that the first output value falls within the critical range.

[0369] In addition, the controller can also adjust the current used for the movement of the first optical component in response to the control of the first output value.

[0370] In addition, since the output value of the photodetector increases in the case of a broken lens, the controller can adjust the power applied to the light source so that the output value of the photodetector of the first optical component used between the first and second positions falls within a critical range.

[0371] Furthermore, the controller can detect abnormal conditions as either overcurrent or an abnormality (breakage) of the first optical component, using not only the first output value but also light received from the first optical component located between the first and second heights.

[0372] Furthermore, the critical range can be changed in response to at least one of the position of the first optical component and the optical power of the light source. For example, within the critical range, the output value of the photodetector at a first height of the first optical component and the maximum optical power of the light source are set to their maximum values. Additionally, within the critical range, the output value of the photodetector at a second height of the first optical component and the minimum optical power of the light source are set to their minimum values.

[0373] Alternatively, a critical range can be set for each height of the first optical component. Furthermore, the critical range can be set differently in response to the light power of the light source. With this configuration, abnormal states of the first optical component can be detected even when its position changes. Therefore, eye safety can be easily implemented by adjusting the light power illuminating the object.

[0374] Figure 40 This is a separate view showing the first optical component in a camera device according to an embodiment. Figure 41 This is a view showing the output values ​​for the movement of the camera device when the first optical component in the camera device according to an embodiment is separated.

[0375] Reference Figure 40 and Figure 41In the camera device according to the embodiment, as described above, an abnormal state of the first optical component may include separation of the first optical component.

[0376] Figure 41 The output values ​​of the photodetector obtained by experiments (Experiments 1 to 4) for each case in which the lens was separated and the first optical component was properly positioned (normal lens 1 to normal lens 3) are shown.

[0377] For example, the separation of the first optical component may include the case where the first optical component is separated from the lens holder, the case where the lens is separated from the lens barrel, the case where the lens barrel or the lens is separated, the case where the first optical component is separated from the optical axis, etc.

[0378] Since the amount of light reflection decreases when the first optical component is separated, the output value of the photodetector may also decrease.

[0379] Therefore, when the second output value is less than the critical range, the controller can detect the abnormal state as the separation of the first optical component. For example, the controller can increase the output of the light source to make the second output value fall within the critical range or output an alarm regarding the separation of the first optical component.

[0380] Furthermore, even if the output value of the photodetector deviates from the critical range when the first optical component moves from the first height to the second height, the controller can detect the abnormal state.

[0381] Figure 42 This is a view showing a modified example of the camera device according to this embodiment. Figure 43 It is a perspective view and a bottom view showing the first optical component.

[0382] Reference Figure 42 and Figure 43 In this embodiment, the first optical component may include a first lens barrel and at least one lens housed in the first lens barrel, as described above.

[0383] Additionally, the camera device according to this embodiment may also include a reflecting member RM disposed on the lower surface of the first lens barrel 122 or lens 121.

[0384] For example, the reflective member RM can be disposed on the lower surface of the lens closest to the light source in the at least one lens 121, or on the lower surface of the first lens barrel 122.

[0385] The reflective element RM can be made of a material with high reflectivity to light. For example, the reflective element RM can be made of metal.

[0386] Additionally, the reflective element RM can be disposed along the edge of the lens 121. For example, the reflective element RM can form a closed loop along the edge of the lens 121. In this case, the reflective element RM can be disposed continuously or discontinuously. With this configuration, the reflective element RM is not located within the field of view of the light emitted from the light source LS, thus reducing light loss.

[0387] Alternatively, the reflective member RM can be positioned below the first lens barrel 122 and outside the viewing angle of the light source LS, so that light reflection can be performed regardless of the movement (first position and second position) of the first optical component 120.

[0388] Due to the reflective element RM, the output value of the photodetector PD can be increased. Therefore, the resolution can be increased when detecting or determining abnormal conditions of the first optical element 120.

[0389] Figure 44 This is a construction diagram of a camera device according to another embodiment. Figure 45 This is a structural diagram of a light emitting unit and a light receiving unit in a camera device according to another embodiment. Additionally, Figure 46 This is a cross-sectional view of a camera device according to another embodiment. Figure 47 This is another cross-sectional view of a camera device according to another embodiment. Additionally, Figure 48 This is a structural diagram illustrating the connection between a light emitting unit, a light receiving unit, and a controller in a camera device according to another embodiment.

[0390] Reference Figures 44 to 48 According to another embodiment, a camera device 10A may include a substrate 1050, a light emitting unit 1010, a light receiving unit 1030, and a cover member 1070. In this camera device 10A, the substrate 1050 corresponds to the aforementioned substrate (main substrate, connecting substrate, etc.), and the light emitting unit 1010 corresponds to the aforementioned light emitting unit 1 (see...). Figure 3 The light receiver 1030 corresponds to the light receiver 2 described above (see Figure 3 ), and the cover member 1070 corresponds to the cover 400 described above (see Figure 3 Therefore, in addition to the above, the following description applies to the component. Furthermore, the structure that controls the opening and closing of the shutter component via the controller described later can also be applied to the camera module 10 described above (see reference). Figure 3 ).

[0391] The substrate 1050 can support the light emitting unit 1010 and the light receiving unit 1030. The substrate 1050 can be electrically connected to the light emitting unit 1010 and the light receiving unit 1030. The substrate 1050 can be a circuit board. The substrate 1050 may include a wiring layer for supplying power to the light emitting unit 1010 and the light receiving unit 1030, and can be a printed circuit board (PCB) formed of multiple resin layers. For example, the substrate 1050 may include at least one of a rigid PCB, a metal core PCB (MCPCB), a flexible PCB (FPCB), and a rigid-flex PCB (RFPCB).

[0392] Additionally, the substrate 1050 may include a synthetic resin containing glass, resin, epoxy resin, etc., and may include ceramics with excellent thermal conductivity and metals with insulating surfaces. The substrate 1050 may have a shape such as a plate or a lead frame, but is not limited thereto. Furthermore, although not shown in the figures, Zener diodes, voltage regulators, resistors, etc., may be further disposed on the substrate 1050, but the present invention is not limited thereto.

[0393] An insulating layer (not shown) or a protective layer (not shown) may be disposed on the substrate 1050. The insulating layer or the protective layer may be disposed on at least one of one surface and another surface of the substrate 1050.

[0394] A light emitting unit 1010 may be disposed on a substrate 1050. The light emitting unit 1010 may emit light. The light emitting unit 1010 may emit light with a set intensity in a set direction. For example, the light emitting unit 1010 may emit light toward the front surface of the light emitting unit 1010, for example, an object may be positioned in the light emitting direction of the light emitting unit 1010.

[0395] A light receiver 1030 may be disposed on a substrate 1050. The light receiver 1030 can detect light. The light receiver 1030 can detect light emitted from the light emitter 1010. The light receiver 1030 can detect light reflected by an object. Specifically, the light receiver 1030 can detect light emitted from the light emitter 1010 and reflected by an object.

[0396] In other words, the camera device 10A can be a time-of-flight (TOF) camera, which calculates the depth map of an object based on light information emitted toward the object, reflected by the object, and returned.

[0397] Additionally, the camera device 10A may also include a coupling part (not shown), a connection part (not shown), and a controller 1730.

[0398] The connector can be attached to an optical device, which will be described below. The connector may include a circuit board and terminals disposed on the circuit board. For example, the terminals may be connectors for making physical and electrical connections with the optical device.

[0399] A connecting portion may be disposed between the substrate 1050 and the connecting portion. The connecting portion may connect the substrate 1050 and the connecting portion. For example, the connecting portion may include a flexible PCB (FBCB) and may electrically connect the circuit board of the substrate 1050 and the connecting portion.

[0400] The controller 1730 can control the opening and closing of the shutter member 1400. Specifically, the controller 1730 can control the opening and closing of the shutter member 1400 based on the amount of light incident on the light receiving element 1230. (Refer to the following...) Figures 48 to 52 A more detailed description of the controller 1730.

[0401] Furthermore, when describing the light emitting unit 1010 in more detail, the light emitting unit 1010 may be disposed on the substrate 1050. The light emitting unit 1010 may include a light source 1210, a first housing 1110, a diffuser 1300, a second housing 1120, a shutter member 1400, and a light receiving element 1230.

[0402] The light source 1210 can be disposed on the substrate 1050. The light source 1210 can directly contact the upper surface of the substrate 1050 and can be electrically connected to the substrate 1050.

[0403] The light source 1210 may include a light-emitting element. For example, the light source 1210 may include at least one light-emitting element selected from a light-emitting diode (LED), a vertical-cavity surface-emitting laser (VCSEL), an organic light-emitting diode (OLED), and a laser diode (LD).

[0404] The light source 1210 may include one or more light-emitting elements. When the light source 1210 includes multiple light-emitting elements, the multiple light-emitting elements may be arranged on the substrate 1050 along a predetermined pattern. Specifically, the multiple light-emitting elements may be configured such that the regions from which light is emitted from the multiple light-emitting elements (e.g., at least one opening for emitting light) have a predetermined rule.

[0405] The light source 1210 can emit light with a set wavelength. Specifically, the light source 1210 can emit visible light or infrared light. For example, the light source 1210 can emit visible light with a wavelength of about 380 nm to about 700 nm. In addition, the light source 1210 can emit infrared light with a wavelength of about 700 nm to about 1 mm.

[0406] A first housing 1110 may be disposed on a substrate 1050. The first housing 1110 may be disposed on a light source 1210. The first housing 1110 may be configured to cover the light source 1210. For example, the first housing 1110 may include a receiving space configured to receive the light source 1210 therein. The receiving space of the first housing 1110 may have a width and height greater than the width and height of the light source 1210. Therefore, the inner surface of the first housing 1110, specifically the inner surface of the first housing 1110 formed by the receiving space, may be spaced apart from the light source 1210 without contacting it.

[0407] The first housing 1110 can contact the upper surface of the substrate 1050. For example, the first housing 1110 can directly contact the substrate 1050 via a separate adhesive member (not shown) and can be fixed to the upper surface of the substrate 1050. Alternatively, the first housing 1110 can be fixed by a fixing member (such as fixing protrusions and fixing grooves formed on the upper surfaces of the first housing 1110 and the substrate 1050, respectively) or by a fastening member (such as a screw).

[0408] The first housing 1110 may include a first opening O1. The first opening O1 may be disposed on the upper surface of the first housing 1110. The first opening O1 may be a hole passing through both the upper surface and the inner surface of the first housing 1110. The first opening O1 may be disposed in a region corresponding to the light source 1210. Specifically, the first opening O1 may be disposed in a region that vertically overlaps with the light source 1210. More specifically, the center of the light source 1210 may vertically overlap with the center of the first opening O1. Considering the directivity angle of the light source 1210, the width of the first opening O1 may be greater than the width of the light source 1210.

[0409] The first housing 1110 may include at least one material selected from resin and metal. For example, the first housing 1110 may include a thermoplastic resin or a thermosetting resin. Alternatively, the first housing 1110 may include at least one metallic material selected from silver (Ag), copper (Cu), gold (Au), platinum (Pt), titanium (Ti), magnesium (Mg), chromium (Cr), molybdenum (Mo), nickel (Ni), tin (Sn), aluminum (Al), stainless steel, and alloys thereof.

[0410] A diffuser 1300 may be disposed on the first housing 1110. The diffuser 1300 may be disposed in the region corresponding to the first opening O1. The diffuser 1300 may be disposed on the first opening O1. The diffuser 1300 may be connected to the first housing 1110. For example, the diffuser 1300 may be disposed on a stepped portion of the first housing 1110 formed in a stepped shape on the first opening O1, and may be connected to the first housing 1110.

[0411] A diffuser 1300 can be disposed on the light source 1210. The diffuser 1300 can be disposed on the path through which the light emitted from the light source 1210 travels. For example, the diffuser 1300 can be disposed in a region that vertically overlaps with the light source 1210. Specifically, the center of the diffuser 1300 can vertically overlap with the center of the light source 1210.

[0412] The diffuser 1300 can control the path of light emitted from the light source 1210. For example, the diffuser 1300 can converge, diffuse, or scatter the light emitted from the light source 1210. The diffuser 1300 can emit light emitted from the light source 1210 in various cross-sectional shapes (such as circular, elliptical, and rectangular shapes). Therefore, the diffuser 1300 can protect an object by preventing the light from the light source 1210 from directly shining on it. For example, the diffuser 1300 can prevent the light from the light source 1210 from directly shining on photosensitive areas, such as the human eye or skin.

[0413] The second housing 1120 may be disposed on the substrate 1050. The second housing 1120 may be disposed on the light source 1210, the first housing 1110, and the diffuser 1300. The second housing 1120 may be configured to cover the light source 1210, the first housing 1110, and the diffuser 1300. For example, the second housing 1120 may include a receiving space configured to accommodate components 210, 110, and 300 therein.

[0414] The second housing 1120 can contact the upper surface of the substrate 1050. For example, the second housing 1120 can directly contact the substrate 1050 via a separate adhesive member (not shown) and can be fixed to the upper surface of the substrate 1050. Alternatively, the second housing 1120 can be fixed by a fixing member (such as fixing protrusions and fixing grooves formed on the upper surfaces of the second housing 1120 and the substrate 1050, respectively) or by a fastening member (such as a screw).

[0415] The receiving space of the second housing 1120 can have a greater width and height than the first housing 1110. Therefore, the inner surface of the second housing 1120 and the outer surface of the first housing 1110 can be spaced apart from each other without contacting each other, and a predetermined space can be formed between them.

[0416] Additionally, the second housing 1120 may be spaced apart from the diffuser 1300. Specifically, the inner surface of the second housing 1120 facing the upper surface of the diffuser 1300 may be disposed above the upper surface of the diffuser 1300. Therefore, a space, as will be described below, may be formed between the diffuser 1300 and the shutter member 1400, for example, a space in which light can move.

[0417] The second housing 1120 may include a second opening O2. The second opening O2 may be disposed on the upper surface of the second housing 1120. The second opening O2 may be a hole passing through the upper surface and the inner surface of the second housing 1120.

[0418] The second opening O2 can be located in the region corresponding to the first opening O1. The center of the second opening O2 can vertically overlap with the center of the first opening O1. Alternatively, the second opening O2 can be located in the region corresponding to the diffuser 1300. The center of the second opening O2 can vertically overlap with the center of the diffuser 1300. Considering the emission direction and radiation elevation angle of the light passing through the diffuser 1300, the width of the second opening O2 can be greater than or equal to the width of the first opening O1.

[0419] The second housing 1120 may comprise at least one material selected from resin and metal. For example, the second housing 1120 may comprise a thermoplastic resin or a thermosetting resin. Alternatively, the second housing 1120 may comprise at least one metallic material selected from silver (Ag), copper (Cu), gold (Au), platinum (Pt), titanium (Ti), magnesium (Mg), chromium (Cr), molybdenum (Mo), nickel (Ni), tin (Sn), aluminum (Al), stainless steel, and alloys thereof. The second housing 1120 may comprise the same material as the first housing 1110.

[0420] The shutter component 1400 can be disposed on the second housing 1120. The shutter component 1400 can be disposed in the region corresponding to the second opening O2. The shutter component 1400 can be coupled to the second housing 1120. Alternatively, the shutter component 1400 can be connected to the substrate 1050. For example, the shutter component 1400 can be electrically connected to the substrate 1050 via connecting wiring (not shown), a flexible PCB (FPCB), or the like.

[0421] The shutter member 1400 can be disposed on the diffuser 1300. The shutter member 1400 can be disposed on the path of light emitted from the diffuser 1300 and spaced at a predetermined distance from the diffuser 1300. The shutter member 1400 can be disposed in a region that vertically overlaps with the diffuser 1300. For example, the center of the shutter member 1400 can overlap with the center of the diffuser 1300.

[0422] The shutter member 1400 can allow or block light emitted from the light source 1210. For example, the shutter member 1400 can control the path of light by opening and closing the second opening O2. Specifically, the shutter member 1400 can open and close the second opening O2 according to a signal applied from the controller 1730. The shutter member 1400 can allow or block light passing through the diffuser 1300. In other words, the shutter member 1400 can allow or block light emitted from the light source 1210 to the outside of the camera device 10A towards the object.

[0423] The light receiving element 1230 can be disposed on the substrate 1050. The light receiving element 1230 can be configured to directly contact the upper surface of the substrate 1050. The light receiving element 1230 can be electrically connected to the substrate 1050.

[0424] The optical receiving element 1230 may include at least one of a photodiode PD, a phototransistor, a photogate, and an optoelectronic IC.

[0425] A light receiving element 1230 may be disposed between the first housing 1110 and the second housing 1120. Specifically, the light receiving element 1230 may be disposed in the region between the outer surface of the first housing 1110 and the inner surface of the second housing 1120. One or more light receiving elements 1230 may be disposed in this region.

[0426] The light receiving element 1230 can receive light emitted from the light source 1210. The light receiving element 1230 can receive light corresponding to the light emitted from the light source 1210. The light receiving element 1230 can receive visible light or infrared light. For example, when infrared light with a wavelength range of approximately 700 nm to approximately 1 mm is emitted from the light source 1210, the light receiving element 1230 can receive infrared light with a wavelength range of approximately 700 nm to approximately 1 mm.

[0427] The light receiving element 1230 can receive light reflected by the shutter member 1400. Specifically, the light receiving element 1230 can receive light reflected from the closed shutter member 1400 in the light emitted from the light source 1210 and passing through the diffuser 1300. In other words, the light receiving element 1230 can be positioned where a portion of the light emitted from the light source 1210 can be received. Taking into account the incident light reflected by the shutter member 1400, the light receiving element 1230 can be positioned closer to the second housing 1120 than the first housing 1110. The shutter member 1400 can be controlled by the amount of light received by the light receiving element 1230. For example, the controller 1730 can control the opening and closing of the shutter member 1400 based on the amount of light received from the light receiving element 1230.

[0428] In other words, according to another embodiment, the camera device 10A can detect whether the light source 1210 and / or the diffuser 1300 are damaged or separated by setting the shutter member 1400 and the light receiving element 1230. Furthermore, the power of the light source 1210 can be controlled based on the amount of light received by the light receiving element 1230, thereby further improving safety.

[0429] Please refer to the description below. Figure 49 and Figure 50 The light emitted to the outside and the light incident on the light receiving element 1230 according to the opening and closing of the shutter member 1400 will be described in more detail. Additionally, reference will be made to the description below. Figure 51 and Figure 52 A more detailed description of the opening and closing operation of the shutter component 1400.

[0430] Furthermore, when describing the light receiver 1030 in more detail, the light receiver 1030 may be disposed on the substrate 1050. The light receiver 1030 may include an image sensor 1250, a third housing 1130, and a lens member 1500.

[0431] Image sensor 1250 can be disposed on substrate 1050. Image sensor 1250 can be in direct contact with the upper surface of substrate 1050. Image sensor 1250 can be electrically connected to substrate 1050. Image sensor 1250 can be spaced apart from light source 1210. Here, image sensor 1250 and light source 1210 can be disposed on the same substrate 1050. However, the embodiment is not limited to this, and image sensor 1250 and light source 1210 can be disposed on different substrates. In this case, the substrates on which image sensor 1250 and light source 1210 are respectively disposed can be electrically connected to each other and spaced apart from each other.

[0432] Image sensor 1250 can detect light. Image sensor 1250 can detect light reflected from an object and incident on camera device 10A. Image sensor 1250 can detect light having a wavelength corresponding to the light emitted from light source 1210. Specifically, image sensor 1250 can detect the depth map of an object by detecting the light emitted from light source 1210 and reflected from the object.

[0433] A third housing 1130 may be disposed on the substrate 1050. The third housing 1130 may be disposed on the image sensor 1250. The third housing 1130 may be configured to cover the image sensor 1250. For example, the third housing 1130 may include a receiving space configured to receive the image sensor 1250 therein. The receiving space of the third housing 1130 may have a width and height greater than the width and height of the image sensor 1250. Therefore, the inner surface of the third housing 1130, specifically the inner surface of the third housing 1130 formed by the receiving space, may be spaced apart from the image sensor 1250 without contacting it.

[0434] The third housing 1130 can contact the upper surface of the substrate 1050. For example, the third housing 1130 can directly contact the substrate 1050 via a separate adhesive member (not shown) and can be fixed to the upper surface of the substrate 1050. Alternatively, the third housing 1130 can be fixed by fixing members (such as fixing protrusions and fixing grooves formed on the upper surfaces of the third housing 1130 and the substrate 1050, respectively) or by fastening members (such as screws).

[0435] The third housing 1130 may include a third opening O3. The third opening O3 may be disposed on the upper surface of the third housing 1130. The third opening O3 may be a hole passing through the upper surface of the third housing 1130 and the inner surface of the first housing 1110. The third opening O3 may be disposed in the region corresponding to the image sensor 1250. Specifically, the third opening O3 may be disposed in the region that vertically overlaps with the image sensor 1250.

[0436] The third housing 1130 may comprise at least one material selected from resin and metal. For example, the third housing 1130 may comprise a thermoplastic resin or a thermosetting resin. Additionally, the third housing 1130 may comprise silver (Ag), copper (Cu), gold (Au), platinum (Pt), titanium (Ti), magnesium (Mg), chromium (Cr), molybdenum (Mo), nickel (Ni), tin (Sn), aluminum (Al), stainless steel, and alloys thereof. The third housing 1130 may comprise the same material as the first housing 1110 and the second housing 1120.

[0437] Lens member 1500 may be disposed on image sensor 1250. Lens member 1500 may be spaced apart from image sensor 1250. Lens member 1500 may be disposed on third housing 1130. Lens member 1500 may be disposed in the region corresponding to third opening O3. Lens member 1500 may be inserted into third opening O3 and connected to third housing 1130.

[0438] Lens member 1500 may be disposed on image sensor 1250. Lens member 1500 may be spaced apart from image sensor 1250 and may include at least one lens. Lens member 1500 allows light incident on light receiver 1030 (e.g., light reflected by an object toward image sensor 1250) to pass through. For this purpose, lens member 1500 may be configured such that an optical axis corresponds to the optical axis of image sensor 1250.

[0439] A lens member 1500 may be disposed on the third housing 1130. The lens member 1500 may be disposed in the region corresponding to the third opening O3. A portion of the lens member 1500 may be inserted into the third opening O3 and connected to the third housing 1130. The upper surface of the lens member 1500 may be disposed above the upper surface of the third housing 1130. A partial region of the lens member 1500 may be disposed in the third opening O3 and may protrude from the upper surface of the third housing 1130.

[0440] The light receiving unit 1030 may also include a filter (not shown). The filter may be disposed between the image sensor 1250 and the lens member 1500. The filter may be coupled to the third housing 1130.

[0441] A filter allows light with a set wavelength to pass through. Specifically, the filter allows light with a wavelength corresponding to the light source 1210 from various wavelengths incident on the light receiving unit 1030 to pass through the lens member 1500, while blocking light with different wavelengths.

[0442] Camera device 10A may include a cover member 1070. The cover member 1070 may be disposed on a substrate 1050. The cover member 1070 may be disposed on a light emitting portion 1010 and a light receiving portion 1030. For example, the cover member 1070 may include a receiving space configured to receive the light emitting portion 1010 and the light receiving portion 1030, and the light emitting portion 1010 and the light receiving portion 1030 may be disposed within the receiving space. The cover member 1070 may be configured to cover the light emitting portion 1010 and the light receiving portion 1030, and may be in direct contact with the light emitting portion 1010 and the light receiving portion 1030.

[0443] The cover member 1070 may include a material with predetermined rigidity and reliability. Therefore, the cover member 1070 can protect the light emitting part 1010 and the light receiving part 1030 disposed therein from external impacts. Additionally, the cover member 1070 may be a non-magnetic material. The cover member 1070 may include a metallic material. The cover member 1070 may be formed of a metal plate. The cover member 1070 may be electrically connected to the substrate 1050 and the grounding electrode. Therefore, the cover member 1070 can be grounded. Furthermore, the cover member 1070 may include a material capable of shielding electromagnetic interference (EMI). In this case, the cover member 1070 may be referred to as an "EMI shielding can". Therefore, the camera device 10A can prevent other adjacent modules from malfunctioning due to electromagnetic waves generated by the camera device 10A, and also prevent the camera device 10A from malfunctioning due to electromagnetic waves generated by other adjacent modules.

[0444] The cover member 1070 may include a plurality of holes. For example, the cover member 1070 may include a first hole hh1 and a second hole hh2 spaced apart from each other.

[0445] The first hole hh1 can be disposed in the region corresponding to the light emitting part 1010. Specifically, the first hole hh1 can be disposed in the region corresponding to the second opening O2. More specifically, the first hole hh1 can be disposed in the region overlapping with the shutter member 1400. The first hole hh1 can have a width corresponding to or different from the width of the shutter member 1400. A portion of the shutter member 1400 can be inserted and disposed in the first hole hh1. In this case, the cover member 1070 can fix the position of the shutter member 1400 and support the shutter member 1400.

[0446] The second hole hh2 can be disposed in the region corresponding to the light receiving portion 1030. Specifically, the second hole hh2 can be disposed in the region corresponding to the third opening O3. More specifically, the second hole hh2 can be disposed in the region overlapping with the lens member 1500. The second hole hh2 can have a width corresponding to or different from the width of the lens member 1500. A portion of the lens member 1500 can be inserted into and disposed in the second hole hh2. In this case, the cover member 1070 can fix the position of the lens member 1500 and support the lens member 1500. In addition, the upper surface of the lens member 1500 can be disposed above the upper surface of the cover member 1070. A local area of ​​the lens member 1500 can protrude from the upper surface of the cover member 1070.

[0447] The cover member 1070 may include a partition wall portion 1075. At least one partition wall portion 1075 may be disposed between the light emitting portion 1010 and the light receiving portion 1030. The partition wall portion 1075 may have a shape extending from the inner surface of the receiving space of the cover member 1070 toward the upper surface of the substrate 1050.

[0448] The partition wall 1075 may have a width corresponding to the width between the light emitting part 1010 and the light receiving part 1030. Specifically, the partition wall 1075 may be configured to have a width corresponding to the area between the second housing 1120 and the third housing 1130 to stably fix the light emitting part 1010 and the light receiving part 1030.

[0449] Additionally, refer to Figure 47 This eliminates the need for the partition wall 1075 of the cover member 1070. For example, the first housing 1110 and the third housing 1130 can be integrally formed, and the integrally formed housing can include multiple receiving spaces configured to each receive the light source 1210 and the image sensor 1250. In this case, at least one sidewall configured to separate the light source 1210 from the image sensor 1250 (e.g., at least one sidewall shared by the first housing 1110 and the third housing 1130) can be used as the aforementioned partition wall 1075.

[0450] When the first housing 1100 and the third housing 1300 are integrally formed, the second housing 1120 can be disposed on the first housing 1100 and the third housing 1300. For example, one region of the second housing 1120 can be attached to the upper surface 1050 of the substrate, and another region of the second housing 1120 can be integrally formed with the upper surfaces of the integrally formed first housing 1100 and third housing 1300. Therefore, the second housing 1120 can be attached to the substrate 1050 and the first housing 1100 and third housing 1300. In addition, the first to third housings 1100, 11200 and 1300 can be integrally formed, but the present invention is not limited thereto.

[0451] Additionally, the camera device 10A may also include a detection unit 1730. The detection unit 1730 may be connected to the controller 1730 and may include at least one sensor. For example, the detection unit 1730 may include at least one sensor capable of detecting impact or acceleration, such as a vibration sensor, impact detection sensor, gyroscope sensor, and accelerometer sensor. The detection unit 1730 can detect impacts or accelerations applied to the camera device 10A.

[0452] Figure 49 and Figure 50 This is a view showing the light movement path in the light emitting section of a camera device according to another embodiment, based on the opening and closing of the shutter member.

[0453] Refer to 49 and Figure 50 The shutter component 1400 can allow light emitted from the light source 1210 to pass through or block light emitted from the light source.

[0454] First, refer to Figure 49 According to another embodiment, the shutter component 1400 can be closed (OFF). For example, the shutter component 1400 can be closed by a signal applied from the controller 1730.

[0455] When the shutter component 1400 is closed, the light emitted from the light source 1210 will not be emitted to the outside of the camera device 10A. Specifically, the light emitted from the light source 1210 can pass through the diffuser 1300, but will not be emitted to the outside of the camera device 10A due to the closed shutter component 1400.

[0456] In this configuration, the light LL1 passing through the diffuser 1300 can be incident on the light receiving element 1230 of the light emitting unit 1010. Specifically, a portion of the light LL1 passing through the diffuser 1300 can be reflected by the shutter member 1400, and a portion of the reflected light LL2 reflected by the shutter member 1400 can be reflected by the light receiving element 1230. During this process, the light receiving element 1230 can receive a portion of the light emitted from the light source 1210.

[0457] In addition, such as Figure 50 As shown, shutter component 1400 can be opened (ON). For example, shutter component 1400 can be opened by a signal applied from controller 1730.

[0458] When the shutter member 1400 is open, light emitted from the light source 1210 can be emitted to the outside of the camera device 10A. Specifically, the light emitted from the light source 1210 can pass through the diffuser 1300, and the light LL1 passing through the diffuser 1300 can be emitted to the outside of the camera device 10A through the open shutter member 1400. In other words, the light LL1 passing through the diffuser 1300 can be emitted toward an object located in front of the camera device 10A. Thereafter, the light reflected by the object can be incident on the light receiving section 1030 of the camera device 10A.

[0459] Light can be incident on the light receiving element 1230 of the light emitting section 1010. For example, a portion of the light LL1 passing through the diffuser 1300 can be reflected by components of the camera device 10A (e.g., the second housing 1120, the shutter member 1400, the cover member 1070, etc.) and a small amount can be incident on the light receiving element 1230. In addition, when the shutter member 1400 is open, light from outside the camera device 10A (e.g., external light) can be incident on the light receiving element 1230.

[0460] The controller 1730 can control the opening and closing of the shutter member 1400 based on the light received by the light receiving element 1230. Specifically, the controller 1730 can control the opening and closing of the shutter member 1400 based on the wavelength and amount of light received by the light receiving element 1230.

[0461] For example, controller 1730 can supply power to light source 1210 when shutter member 1400 is closed (see...). Figure 49 Therefore, the light source 1210 can emit light, and the light emitted from the light source 1210 can be incident on the diffuser 1300. Additionally, the light LL1 passing through the diffuser 1300 can be reflected by the shutter member 1400 and incident on the light receiving element 1230. At this time, the light receiving element 1230 can receive light with a wavelength corresponding to the light source 1210, and when the received light meets the set light intensity range, the controller 1730 can determine that the diffuser 1300 is in a normal state. Conversely, when the received light does not meet the set light intensity range, the controller 1730 can determine that the diffuser 1300 is in an abnormal state.

[0462] When the diffuser 1300 is determined to be in a normal state, the controller 1730 can open the shutter component 1400 (see...). Figure 50 Therefore, light emitted from the light source 1210 can pass through the shutter member 1400 and be directed toward the object. Additionally, when the diffuser 1300 is determined to be in an abnormal state, the controller 1730 can keep the shutter member 1400 closed, or close the shutter member 1400 when it is in the open state.

[0463] Furthermore, the controller 1730 can control the operation of the camera device 10A based on the signals detected by the detection unit 1730. Specifically, when the detection unit 1730 detects an impact or acceleration exceeding a set range, the controller 1730 can control the operation of the operating light source 1210 and the shutter component 1400.

[0464] For example, such as Figure 49 As shown, when the detection unit 1730 detects an impact or acceleration exceeding the set range while the shutter component 1400 is closed, the controller 1730 can turn off the light source 1210 and keep the shutter component 1400 closed.

[0465] In addition, such as Figure 50 As shown, when the detection unit 1730 detects an impact or acceleration exceeding the set range while the shutter component 1400 is open and the light source 1210 is on, the controller 1730 can turn off the light source 1210 and close the open shutter component 1400.

[0466] Therefore, the camera device 10A can confirm whether the light emitting unit 1010 is damaged, whether components are separated, etc., and in particular, whether the diffuser 1300 is in normal working order. Thus, the safety of the light supplied to the object through the diffuser 1300 can be confirmed, thereby further improving safety.

[0467] In the following text, reference will be made to Figure 51 and Figure 52 A method for confirming the normal operation of a camera device according to another embodiment is described in more detail. Figure 51 and Figure 52 This is a view showing whether the camera device is functioning correctly according to another exemplary embodiment.

[0468] Reference Figure 51 and Figure 52 According to another embodiment, the method for confirming the normal operation of the camera device 10A may include: closing the shutter component (S10), emitting light (S20), receiving light by the light receiving element (S30), and controlling the opening and closing of the shutter component (S40).

[0469] First, the operation of closing the shutter member (S10) can be an operation of closing the shutter member 1400 of the light emitting unit 1010. For example, when the shutter member 1400 is open, operation S10 can be an operation of closing the shutter member 1400. Alternatively, operation S10 can be an operation of confirming that the shutter member 1400 is in a closed state. For example, operation S10 can be an operation of confirming and maintaining the closed state when the shutter member 1400 is closed. In other words, in operation S10, the shutter member 1400 can remain in a closed state. Therefore, in operation S10, light is not introduced into the camera device 10A from outside the camera device 10A. Additionally, operation S10 can be an operation of not supplying power to the light source 1210.

[0470] Subsequently, the operation of emitting light (S30) can be performed. The operation of emitting light (S30) can be the operation of supplying power to the light source 1210. In the operation of emitting light (S30), the light source 1210 can emit light by being powered. The light source 1210 can emit light toward the diffuser 1300. The light source 1210 can emit light toward the shutter member 1400.

[0471] Subsequently, an operation (S50) can be performed whereby light is received by a light-receiving element. This operation (S50) can be performed by receiving light through a light-receiving element 1230 disposed between the first housing 1110 and the second housing 1120. The operation (S50) can also be performed by receiving a portion of the light emitted from the light source 1210. In this operation (S50), the light-receiving element 1230 can receive light reflected by the shutter member 1400. Specifically, operation S50 can be performed by the light-receiving element 1230 receiving a portion of the light reflected by the shutter member 1400 that has passed through the diffuser 1300.

[0472] Subsequently, the operation of controlling the opening and closing of the shutter component can be performed (S70). Operation S70 can be an operation of controlling the opening and closing of the shutter component 1400 based on the light incident on the light receiving element 1230.

[0473] Specifically, the operation of controlling the opening and closing of the shutter member (S70) may include determining the amount of light received by the light receiving element 1230. Specifically, the operation of determining the amount of light may be an operation of determining whether the shutter member 1400 is open or closed based on the amount and wavelength of light incident on the light receiving element 1230.

[0474] For example, in the light receiving operation (S50), the light receiving element 1230 can receive light having a wavelength band corresponding to the light source 1210. However, in the light receiving operation (S50), light deviating from the set light amount range can be incident on the light receiving element 1230. Here, the set light amount range can be the value of the amount of light reflected by the shutter member 1400 and incident on the light receiving element 1230 when the components of the light emitting unit 1010 are normal. In addition, in the light receiving operation (S50), light having a set light amount range can be incident on the light receiving element 1230, but light having a wavelength band that does not correspond to the light source 1210 can be incident on it.

[0475] Specifically, due to damage or separation of components of the light emitting unit 1010, light deviating from the set light intensity range may be incident on the light receiving element 1230. For example, due to damage or separation of the diffuser 1300, light deviating from the set range (such as being less than or exceeding the set light intensity range) may be incident on the light receiving element 1230.

[0476] In this situation, the controller 1730 can determine that a component of the light emitting unit 1010 is not in a normal state, such as being damaged or separated. Therefore, in the operation of controlling the opening and closing of the shutter member (S70), the controller 1730 can keep the shutter member 1400 closed and not open it. Additionally, in the operation of controlling the opening and closing of the shutter member, the controller 1730 can turn off the power to the light source 1210. Therefore, the camera device 10A according to another embodiment can prevent abnormal light from being emitted towards the object, thereby improving safety.

[0477] Furthermore, during operation S70, light with a wavelength corresponding to the light source 1210 can satisfy the set light intensity range and can be incident on the light receiving element 1230. In this case, the controller 1730 can determine that the components of the light emitting unit 1010 are in a normal state and open the shutter member 1400. Therefore, light passing through the diffuser 1300 can be emitted towards the object by passing through the opened shutter member 1400. In other words, the camera device 10A can emit safe light with a set light intensity towards the object.

[0478] The operation of controlling the opening and closing of the shutter component (S70) may also include the operation of detecting impact or acceleration.

[0479] The operation of detecting impact or acceleration is the operation of the detection unit 1730 to detect impact or acceleration, and it can be the operation of controlling the opening and closing of the shutter component 1400 based on the detected impact or acceleration.

[0480] The operation of detecting impact or acceleration can be performed after the shutter member 1400 is opened. For example, in the operation of controlling the opening and closing of the shutter member (S70), after the shutter member 1400 is opened, the detection unit 1730 can detect the impact or acceleration applied to the camera device 10A. At this time, when the impact or acceleration detected by the detection unit 1730 exceeds a set range, the controller 1730 can turn off the power to the light source 1210. In addition, the controller 1730 can close the shutter member 1400.

[0481] Alternatively, after the shutter component 1400 opens, no impact or acceleration is applied to the camera device 10A, or an impact or acceleration within a set range can be detected. In this case, the controller 1730 can keep the shutter component 1400 open while keeping the power supply to the light source 1210 on without turning it off.

[0482] Furthermore, the operation of detecting impact or acceleration can be performed again during the operation of controlling the opening and closing of the shutter member (S70). Therefore, when the wavelength and amount of light incident on the light receiving element 1230 are satisfied, and the set impact or acceleration in the camera device 10A is also satisfied, the shutter member 1400 can be opened.

[0483] In this situation, the shutter component 1400 can open and emit light toward the object, and in the process, the aforementioned impact or acceleration detection operation can be performed again.

[0484] When the light emitting unit 1010 remains in normal operation and no impact or acceleration within the set range is detected, the camera device 10A can automatically terminate operation after the set operation time. Alternatively, the camera device 10A can be temporarily stopped or terminated by the user during the set operation time.

[0485] In other words, the light emitting unit 1010 of the camera device 10A according to another embodiment may include a light receiving element 1230. Therefore, it can be confirmed whether the light emitting unit 1010 is in a normal state, for example, whether components are damaged or separated. Specifically, it can be confirmed whether the diffuser 1300 is damaged or separated based on the light incident on the light receiving element 1230. Additionally, the camera device 10A may include a detection unit 1730 configured to detect impact or acceleration. Therefore, when an impact or acceleration is applied to the camera device 10A, operation of the camera device 10A can be stopped and the damage or separation of components can be reconfirmed.

[0486] Therefore, the camera device 10A according to another embodiment can effectively determine whether it is operating normally, thereby providing improved security.

[0487] Figure 53 and Figure 54 This is a perspective view of a mobile terminal and a vehicle on which the camera device according to the embodiment is applied. The camera devices 10 and 10A according to the embodiment can be applied to optical devices.

[0488] First, refer to Figure 53 The camera devices 10 and 10A according to the embodiments can be applied to the mobile terminal 20. The mobile terminal 20 according to the embodiments may have a first camera device 10 or 10A and a second camera device 10 or 10A disposed on its rear surface.

[0489] The first camera device is the aforementioned camera device 10 or 10A, and may include a light emitting unit and a light receiving unit. The first camera device may be a time-of-flight (TOF) camera.

[0490] The second camera device 10 or 10A may include an image capture function. Additionally, the second camera device 10 or 10A may include at least one of an autofocus function, a zoom function, and an OIS function. The second camera device 10 or 10A can process image frames of still or moving images acquired by the image sensor in shooting mode or video call mode. The processed image frames can be displayed on a predetermined display and stored in memory. Furthermore, although not shown in the figures, the camera may also be mounted on the front surface of the mobile terminal 20. For example, the first camera device and the second camera device may also centrally perform different functions.

[0491] The autofocus device 2510 and the flash module 2530 can be mounted on the rear surface of the mobile terminal 20.

[0492] The autofocus device 2510 may include one of the packages of the surface-emitting laser element as a light emitting part.

[0493] The autofocus device 2510 may include an autofocus function using a laser. The autofocus device 2510 can be used primarily in conditions where the autofocus function of the images from the camera devices 10 and 10A is degraded, for example, in environments close to 10m or smaller or in dark environments.

[0494] The autofocusing device 2510 may include a light emitting part and a light receiving part. The light emitting part includes a vertical cavity surface-emitting laser (VCSEL) semiconductor element, and the light receiving part is configured to convert light energy into electrical energy, such as a photodiode.

[0495] The flash module 2530 may include a light-emitting element configured to emit light. The flash module 2530 can be operated via camera operation on a mobile terminal or by user control.

[0496] Therefore, the user can use the mobile terminal 20 to capture and display the object. Additionally, the user can effectively identify the object's depth map using the first camera device 10A.

[0497] Additionally, refer to Figure 54 The camera devices 10 and 10A according to the embodiments can be applied to vehicle 3000.

[0498] The vehicle 3000 according to an embodiment may include wheels 13FL and 13FR that rotate by a power source, and predetermined sensors. The sensors may be camera sensors 2000, and camera sensors 2000 may be camera sensors including the aforementioned camera device 10A.

[0499] According to an embodiment, the vehicle 3000 can acquire image information and depth maps through a camera sensor 2000 configured to capture images of the front or surroundings, use the image information and depth maps to determine lane uncertainty, and generate a virtual lane when lane uncertainty is detected.

[0500] For example, camera sensor 2000 can acquire a frontal image by taking a picture of the front of vehicle 3000, and processor (not shown) can acquire image information by analyzing objects included in the frontal image.

[0501] For example, when the camera sensor 2000 captures objects such as a median strip, curb, or roadside trees corresponding to a lane, adjacent vehicles, driving obstacles, and indirect road markings in an image, the processor can detect not only the image information of the object but also its depth map. In other words, this embodiment can provide the occupants of the vehicle 3000 with more specific and accurate information about the object.
