Description

Camera device having a self-aligned structure of a light source and an image sensor and a system using the same

[0001] The present disclosure relates to a camera device having a self-aligned structure in which a light source and an image sensor are arranged, and a system using the same.

[0002] Video devices typically feature a camera module, which contains an image sensor. Recently, camera modules have been incorporated into not only video devices but also general electronic devices.

[0003] Image formation is the process by which light or rays from a subject are reconverged through reflection or refraction by a spherical or aspherical lens to form an image resembling that object. This image formation can be comprised of a focusing element that focuses the light source and a diffusion element that varies the amount of light from the focusing element. Searchlights with image formation optical zoom systems achieve high brightness, uniform light distribution, and ensure visibility of subjects from a distance. Furthermore, these searchlights are compact and high-performance, ensuring portability.

[0004] Previously, most imaging optical zoom system searchlights combined a fixed reflector light with a camera and laser. However, to achieve high-quality images while maintaining portability, manual or automatic zooming is becoming increasingly necessary, ensuring smooth subject visibility, high-quality shooting, and data transmission. This requirement is also present in non-imaging optical systems to achieve clear results.

[0105] The reflector according to the embodiment reflects light output from the light source unit (110) or light reflected from the first reflector or the second reflector. In order to reduce the amount of light output from the light source unit (110) and reaching the image sensor (140), the light-receiving angles of the first and second reflectors, the positions where they are provided, and the shape of the reflector can be set. The shape of the reflector can be hemispherical, flat, etc. The light-receiving angle can be set corresponding to the angle at which the light spreads by adjusting the bending angle of the reflector, and the position where the reflector is provided can be set by adjusting the first and second intervals spaced apart from the light source unit. Accordingly, the noise level of the light of the light source unit (100) can be lowered and the optical power can be improved. The light-receiving angles, positions, shapes of the reflectors, etc. can be set so that the light source unit (110) and the image sensor (140) are self-aligned to form a non-imaging optical system of the camera device.

[0106]

[0107] FIG. 5A and FIG. 5B are exemplary diagrams of image sensor locations of a camera device according to various embodiments of the present disclosure.

[0108] Referring to Fig. 5a, the housing may be made of a transparent and light-absorbing material. The housing may be positioned between the light source unit (110) and the image sensor (140) in the direction of the optical axis while being parallel to the optical path. That is, the image sensor (140) may be positioned in front of the housing on a surface that faces the light source unit (110) in the direction of the optical axis while being parallel to the optical path.

[0109] Referring to FIG. 5b, the housing may be positioned on a surface that is parallel to the optical path and is opposed to the light source unit (110) and the image sensor (140) in the direction of the optical axis. That is, the image sensor (140) may be positioned on a surface that is parallel to the optical path and is opposed to the light source unit (110) in the direction of the optical axis, and may be positioned behind the housing. In this case, the image sensor (140) is positioned between the light source unit (110) and the housing. That is, the position of the image sensor (140) is not limited to inside or outside the housing (130) depending on the case.

[0110]

[0111] FIGS. 6A and 6B are exemplary views of lenses according to various embodiments of the present disclosure.

[0112] Referring to FIGS. 6A and 6B, the lens (120) may be positioned on the optical path of a camera device (e.g., the camera device (100) of FIG. 1) and may be positioned between the light source unit (110) and the image sensor (140). FIG. 6A is an example of a single lens (120), and FIG. 6B is an example of a multiple lens (120).

[0113] The lens (120) according to the embodiment may be a concave lens or a convex lens. In addition, the lens (120) may be provided in a single number and / or in a plurality. For example, the lens (120) may be a plurality of lenses. The plurality of lenses may include a primary lens unit and a secondary lens unit, and the primary lens unit may include a single or a plurality of lenses, and the secondary lens unit may also be similar to the primary lens unit. The secondary lens unit may be positioned close to the light source as a cooking unit that controls the amount of light, and the primary lens unit may be positioned close to the image sensor as a diffusion unit that controls light distribution and illuminance.

[0114] The lens (120) according to the embodiment can perform focusing by a zoom operation while the movement distance trajectories of the secondary lens unit and the primary lens unit are adjusted through asymmetrical corresponding movements in response to the focal length. This means that the movement distance trajectories of the secondary lens unit and the primary lens unit are adjusted by correspondingly moving but asymmetrically according to the focal length.

[0115] According to an embodiment, the zoom operation of the camera device can convert the curved movement of the lens into a vertical movement. For example, the primary lens unit and the secondary lens unit can curve-move according to the trajectory of the formed curve, and the housings of the primary lens unit and the secondary lens unit can move vertically (straight) correspondingly. The number of lenses constituting the lens unit of the camera device of the present disclosure can be provided according to various conditions. For example, the lens of the camera device can include a fixed lens unit and a movable primary lens unit and a secondary lens unit. In this case, the fixed lens unit can perform light gathering through two lenses (e.g., a primary lens and a secondary lens), and focusing by the zoom operation can be performed through one lens of the primary lens unit (e.g., a tertiary lens) and two lenses of the secondary lens unit (e.g., a quaternary lens and a quintic lens). Here, the fact that the movement distance trajectories of the secondary lens part and the primary lens part move asymmetrically in response to the focal length of the lens (120) may mean that the movement distances of the secondary lens part and the primary lens part are different from each other.

[0116] According to an embodiment, a camera device may include a communication unit capable of communicating with an external device. The control unit may perform autofocusing and zoom-in / zoom-out on a subject. Furthermore, the control unit may transmit a captured image of the subject to an external device via the communication unit. Here, the external device may be a server or a monitoring device that performs continuous monitoring of the subject. According to an embodiment, a camera device having a non-focusing optical system may not perform a zoom function.

[0117] The image sensor (140) according to the embodiment may include an image sensor using a CCD, CMOS method, etc. The structure of the image sensor (140) is not limited thereto. In addition, the material of the image sensor (140) may be any semiconductor device.

[0118] The camera device according to the embodiment can be utilized as a CCTV, black box, etc. For example, the camera device can be mounted on aircraft such as drones, helicopters, and airplanes. In another example, the camera device can be mounted on land or water vehicles such as automobiles, ships, and lighthouses. In another example, the camera device can be mounted on underwater vehicles such as submarines, scuba gear, and the underside of ships. Furthermore, the camera device can be utilized for underwater surveillance, multi-purpose helmets, military applications, or firefighting.

[0119]

[0120] FIG. 7 is an example diagram of focusing performance according to various embodiments of the present disclosure.

[0121] Existing camera devices, when using a fixed focus, may have a mismatch between the camera magnification and the illumination magnification due to long-distance lighting distribution. The camera device of the present disclosure (e.g., the camera device (100) of FIG. 1) can perform autofocus and zoom functions for a subject to be photographed, and can easily align the camera magnification and the illumination magnification.

[0122] A camera device according to an embodiment can focus on a subject by asymmetrically adjusting a movement trajectory of a primary lens unit and a movement trajectory of a secondary lens unit. A lens according to an embodiment can focus by a zoom operation while asymmetrically adjusting the movement trajectories of a primary lens unit and a secondary lens unit in response to a focal length. This means that the movement trajectories of a primary lens unit and a secondary lens unit are asymmetrically adjusted in response to a focal length.

[0123] According to an embodiment, the lens includes a plurality of lenses, and the plurality of lenses may be formed to have different degrees of concaveness or convexity. In addition, the primary lens unit and the secondary lens unit may be positioned parallel to each other so that light may be focused or diffused depending on the distance between the lenses.

[0124] Referring to FIG. 7, the camera device may be configured to adjust the distance between the primary lens unit and the secondary lens unit. That is, the camera device may be provided with a cylindrical housing including the primary lens unit and a cylindrical housing including the secondary lens unit having different diameters, and the diameter of the cylindrical housing including the primary lens unit may be larger than the diameter of the cylindrical housing including the secondary lens unit. Accordingly, the camera device may be capable of performing zoom-out / zoom-in of light by adjusting the focal distance between the lenses according to the movement trajectories of the primary lens unit and the secondary lens unit.

[0125] A camera device according to an embodiment determines the irradiation area of ​​a light source corresponding to the amount of light required by an image sensor (e.g., the image sensor (140) of FIG. 1) based on the distance from the subject to be photographed. For example, the control unit can determine the irradiation area of ​​a light source unit in accordance with the amount of light required by the image sensor unit based on the distance from the subject to be photographed.

[0126] According to an embodiment, the camera device is capable of autofocusing and zooming in / out on a subject to be photographed. Furthermore, the camera device can determine the irradiation area in conjunction with the focus adjustment. At this time, the camera device can immediately adjust the irradiation area according to the focus adjustment speed. According to an embodiment, the control unit can calculate the amount of light required for the image sensor in response to the distance at which the subject to be photographed is located.

[0127] Chromatic aberration is a defect in a lens where light of various colors is refracted at different angles and fails to focus on the same surface. This phenomenon is commonly observed at the edges of a subject due to the strong sunlight during outdoor photography. Chromatic aberration typically exists in single lenses. The camera device of the present disclosure can position components to ensure an appropriate amount of light passes through the lens to reduce chromatic aberration and perform a zoom function. However, magnification adjustment by the zoom function can only be utilized in a camera device that forms an imaging optical system.

[0128] In another embodiment, a camera device may include a protrusion on an image sensor. The protrusion may be provided on the image sensor in a form that prevents light from being diffracted by the image sensor and attenuates light scattered by a medium outside the image sensor or the housing. As a result, the protrusion may lower the noise level and improve the sensitivity. For example, the protrusion may be formed of a light-absorbing material. Furthermore, the protrusion may be designed to be deformable in order to attenuate scattered light. This may be to enable a user who has identified diffracted light, scattered light, etc. that may be transmitted through the image sensor to adaptively deform the protrusion while using the camera device to attenuate the diffracted light and scattered light.

[0129] A camera device according to an embodiment may include a telephoto lens and a focus adjustment unit. The camera device may have the telephoto lens in front of an image sensor.

[0130]

[0131] FIG. 8 is an exemplary diagram of a special lens according to various embodiments of the present disclosure.

[0132] A camera device according to an embodiment (e.g., the camera device (100) of FIG. 1) may include at least one of a concave lens, a convex lens, and a special lens. Here, the camera device including the lens may be an imaging optical system camera device.

[0133] A special lens according to an embodiment may be formed to reduce light loss by allowing less light to enter the image sensor. The special lens may be a combination of a concave lens and a convex lens. According to an embodiment, the special lens refracts light output from a light source to reduce the amount of light reaching the image sensor, and may be positioned accordingly. The special lens according to the embodiment disclosed in FIG. 8 may include a convex lens positioned at both edges and a concave lens positioned between the convex lenses to reduce the amount of light reaching the image sensor. As a result, the amount of light may relatively increase in the peripheral area of ​​the image sensor, and the amount of light may relatively decrease in the area where the image sensor is located. However, the special lens may have any shape without limitation as long as the special lens reduces the amount of light reaching the image sensor while allowing the light source and the image sensor to be self-aligned and installed in a camera device. Although not illustrated in the drawings, the special lens is not limited in its position, order, or number of installations as long as it can reduce the amount of light reaching the image sensor and thus reduce light loss. For example, the special lens may be positioned closest to the light source between the light source and the housing as in Fig. 8, but alternatively, another general lens may be positioned closest to the light source followed by the special lens.

[0134]

[0135] FIG. 9 is an exemplary diagram of a light source unit according to various embodiments of the present disclosure.

[0136] The light source unit according to the embodiment illustrated in FIG. 9 uses the shape (1210) of the light source according to FIG. 12, which will be described later, and can be configured to reduce the amount of light directly or indirectly irradiated to the image sensor (140). The light source unit can be configured so that at least a portion of the area is hollow, so that light is not irradiated in the area, thereby reducing the amount of light directly irradiated to the image sensor (140). Alternatively, unlike what is illustrated in the drawing, a light source unit in which no hollow area exists and light is irradiated in all areas may be used, but light may also be prevented from being irradiated in an area overlapping with the image sensor (140) on the light path through a set program or control unit.

[0137] The light source unit (110) according to the embodiment disclosed in FIG. 9 may additionally be equipped with LED modules of other colors around the LED module in order to compensate for color bleeding, refraction, diffraction, etc. that may occur due to light output from the LED module. For example, the single-color LED module of the light source unit (110) may be equipped in a shape composed of a point, a line, or a plane, and LED modules of other colors may be equipped along the boundary of the shape. For another example, another LED module may be equipped in a shape that surrounds the boundary of the LED module of the light source unit (110). For yet another example, the LED module of the light source unit (110) may be equipped on a PCB, and LED modules of other colors may be equipped on the PCB in a shape that surrounds the boundary of the LED module. That is, the LED modules of other colors of the light source unit (110) may be equipped in order to perform color correction of the main LED module.

[0138]

[0139] FIG. 10 is an example diagram of a light source unit formed in a special shape to reduce the amount of light directly irradiated to an image sensor (140) according to various embodiments of the present disclosure.

[0140] The light source unit (110) according to the embodiment may be formed in a shape so that light is not irradiated to a portion overlapping the image sensor (140) on the optical path in order to reduce the amount of light directly irradiated to the self-aligned image sensor (140) and thus reduce the optical power for the image sensor (140).

[0141]

[0142] FIG. 11 is an example diagram including a reflector for reducing the amount of light directly irradiated to an image sensor (140) according to various embodiments of the present disclosure.

[0143] The light source unit (110) according to the embodiment may be designed to have a shape in which a portion overlapping with the image sensor (140) on the optical path is removed in order to reduce the amount of light directly irradiated to the self-aligned image sensor (140) and thus reduce the optical power for the image sensor (140). For example, referring to FIG. 9, the light source unit (110) may be designed in a two-dimensional square shape in which a portion overlapping with the image sensor (140) on the optical path is removed. Accordingly, the optical power of the light output from the light source unit (110) is reduced for the removed portion.

[0144] The light source unit (110) according to the embodiment may be designed to have a metal reflector in a portion overlapping the image sensor (140) on the optical path in order to reduce the amount of light directly irradiated to the self-aligned image sensor, thereby reducing the optical power to the image sensor (140). For example, referring to FIG. 11, the light source unit (110) may have a metal reflector in a portion overlapping the image sensor (140) on the optical path, so that the light output from the light source unit (110) is reflected by the reflector, thereby reducing the optical power directly irradiated to the image sensor (140). However, the material of the reflector is not limited to metal, and any material that can reduce the light directly or indirectly irradiated to the image sensor (140) may be used. Such an effect may be achieved by designing various shapes of the light source unit (110), as shown in FIGS. 10 and 12.

[0145]

[0146] FIG. 12 is an exemplary diagram of a light source unit according to various embodiments of the present disclosure.

[0147] The light source unit (110) may have the form of a two-dimensional light source (1210) or a three-dimensional light source (1220) shaped to reduce light directly irradiated to the image sensor (140) by preventing light from being irradiated in at least some areas. For example, the light source unit (110) may be a point light source that can radiate light in almost all directions. This may correspond to a gas lamp, a lighthouse, an electric spark, etc. For another example, the light source unit (110) may be a linear light source that may be a filament or fluorescent lamp. For another example, the light source unit (110) may be a planar light source that may be an array of LEDs, lasers, or point light sources. In addition, the light source unit (110) may be a special type of light source module that may be an x-cube module.

[0148] According to an embodiment, the light source unit (110) may have any shape that minimizes light directed toward the image sensor (140). This may have the effect of preventing light from being directed toward the image sensor (140), like the light source unit (110) of FIG. 9 or FIG. 10.

[0149]

[0150] FIGS. 13A to 13C are exemplary diagrams of the operation of a reflector of a self-aligning camera according to various embodiments of the present disclosure.

[0151] Referring to FIGS. 13A to 13C, a self-aligning camera (e.g., the self-aligning camera (100) of FIG. 1) may include a reflector. In this case, the reflector may include at least one reflector (151, 152) and a reflector. One arrow in FIG. 13A and below indicates the reflection direction of light output from the light source (110).

[0152] The reflector according to the embodiment may include a first reflector (151) and a second reflector (152). The second reflector (152) is positioned on a surface that is arranged with the first reflector (151) based on the light source (110).

[0153] Referring to Fig. 13a, light output from a light source (110) may be reflected by a first reflector (151) and irradiated toward an image sensor (140). At this time, the light power may be nearly equalized at a long distance. A control unit (e.g., control unit (150) of Fig. 1) may adjust the position of the reflector (reflector) to adjust the area of ​​the reflected light. Accordingly, the control unit may lower the noise level of the light from the light source and improve the light power.

[0154] Referring to FIG. 13b, a second reflector (152) may be placed in front of the light source unit (110) to control light directed to the image sensor (140). The second reflector (152) may be installed to face the surface on which the first reflector (151) is placed with respect to the light source unit (110).

[0155] The embodiment illustrated in Fig. 13c includes a first reflector (151) and a second reflector (152) in the same manner as Fig. 13b, but when the irradiation direction of the light source unit (110) is configured to face forward, light can be irradiated toward the image sensor (140) by changing the position and angle of each reflector. Here, the second reflector (152) can play a role in ensuring that the light reflected from the first reflector (151) corresponds to the shooting range of the image sensor unit (140) and in reducing the light irradiated from the light source from being directly irradiated to the image sensor (140).

[0156]

[0157] Referring to Fig. 14, the control unit can adjust the position of the reflector (first reflector, second reflector). For example, the control unit can place the first reflector (151) on a plane spaced apart from the light source unit (110) by a first distance. Fig. 14 may be an example of spaced apart the first reflector (151) by the first distance.

[0158] The control unit according to the embodiment can control the light power by controlling the irradiation range of the light source unit (110) by moving the positions of the first reflector (151) and the second reflector (152) and can control the correspondence with the shooting range of the image sensor unit (140). The control unit can thereby be configured to obtain image data (results) according to the intention.

[0159] The camera device according to an embodiment of the present disclosure may further include a reflector (153). The reflector (153) may be positioned between the light source unit (110) and the housing unit (130) and facing the image sensor unit (140). The reflector (123) may be provided to reduce light directed directly toward the image sensor unit (140). The reflector (153) may reflect light output from the light source unit (110) or re-reflect light reflected from the first reflector (151) or the second reflector. According to an embodiment, the reflector (153) may be designed in consideration of the correlation between the radiation of the light source and the reflection angle of the reflector (151, 152).

[0160] Although not shown in the drawing, the control unit may be configured to move and control the position of the light source unit (110) to adjust the light irradiation range.

[0161]

[0162] FIGS. 15A and 15B are exemplary diagrams of a camera device forming a non-image-forming optical system according to various embodiments of the present disclosure.

[0163] The camera device of FIGS. 15A and 15B (e.g., the camera device (100) of FIG. 1) may be a camera device forming a non-focusing optical system. In this case, the reflector may include at least one reflector (151, 152) and a reflector (153).

[0164] According to an embodiment, it may be configured in a flat shape, for example, as in Fig. 15a, or in a shape with a convex surface that is partially convex, as in Fig. 15b. For example, it may be formed in a hemispherical shape with one side convex and the other side flat, as shown in the drawing. Here, one side may be in a direction facing the light source. The reflector (153) is illustrated as being provided when the second reflector (152) described above is not installed, but may be provided regardless of the presence or absence of the second reflector (152) when it is necessary to reduce the light directed to the image sensor (140).

[0165]

[0166] FIGS. 16A and 16B are exemplary diagrams of a light source unit according to various embodiments of the present disclosure.

[0167] The light source unit may be configured in the form of a light source module as mentioned in the aforementioned FIG. 12, or in the form of a special form of a light source module such as an x-cube module. According to an embodiment, the light source unit may be of any form that minimizes light directed directly toward the image sensor unit (140). For example, a light source in the form of a lighthouse as shown in FIG. 16a or a light source in the form of an x-cube module as shown in FIG. 16b may be used. While using a light source that does not directly direct light toward the image sensor unit (140) in this way, light irradiated in other directions can be irradiated in an intended direction by adjusting the size, number, and position of reflectors.

[0168]

[0169] FIG. 17 is an exemplary diagram of a camera device having a heat dissipation unit according to various embodiments of the present disclosure.

[0170] As illustrated in FIG. 17, a camera device having a heat dissipation unit according to various embodiments of the present disclosure may further include a heat dissipation unit (160). The heat dissipation unit (160) may be provided at the front or rear depending on the installation structure of the reflector, and the light source (110) may be positioned on the heat dissipation unit (160). According to the embodiment illustrated in the drawing, the heat dissipation unit (160) may include a first heat dissipation plate (161) positioned at the rear of the reflector, and a second heat dissipation plate (162) configured to extend from the first heat dissipation plate (161) and face the inside of the reflector. A light source (110) is disposed on the second heat dissipation plate (162), and light irradiated from the light source (110) may be irradiated toward the image sensor (140) by the reflector. The shape of the heat sink (160), the length of the first heat sink (161) and the second heat sink (162), the position or direction of the light source placed on the second heat sink (162), etc. can be adjusted and changed without limitation according to the requirements or needs, and accordingly, the size and curvature of the reflector can also be changed. The image sensor (140) can be positioned toward the housing (130) at the end of the second heat sink (162) as shown in Fig. 17. However, it is not limited thereto, and the position of the image sensor (140) can be placed adjacent to the front and rear of the housing (130) as well as the end of the second heat sink (162).

[0171]

[0172] The image sensor unit (140) according to the embodiment may include an image sensor using a CCD, CMOS, or other method. The structure of the image sensor is not limited thereto. In addition, the material of the image sensor may be any semiconductor device.

[0173] The self-aligning camera according to the embodiment can be utilized as a CCTV, black box, etc. For example, the self-aligning camera can be mounted on aircraft such as drones, helicopters, and airplanes. In another example, the self-aligning camera can be mounted on land or water vehicles such as cars, ships, and lighthouses. In another example, the self-aligning camera can be mounted on underwater vehicles such as submarines, scuba gear, and the underside of ships. Furthermore, the self-aligning camera can be utilized for underwater surveillance, multi-purpose helmets, military applications, or firefighting.

[0174] Meanwhile, the disclosed embodiments may be implemented in the form of a recording medium storing computer-executable instructions. The instructions may be stored in the form of program code, and when executed by a processor, may generate program modules to perform the operations of the disclosed embodiments.
