Description

Technical Field

[0001] The present application relates to the technical field of camera devices, and in particular to a camera module and electronic equipment. Background Art

[0002] With the rapid development of electronic devices such as smart phones, tablets, and e-readers, lens modules in electronic devices also tend to be diversified in design to meet different shooting needs. Some electronic devices are equipped with periscope camera modules to obtain higher optical magnification shooting effects.

[0003] However, in the related art, when the camera is focusing, stray light easily enters the image sensor, resulting in a decrease in image quality. Summary of the invention

[0004] The embodiments of the present application provide a camera module and an electronic device to solve the problem of stray light entering an image sensor and causing a decrease in imaging quality.

[0005] On the one hand, the present application provides a camera module, comprising:

[0006] The housing has a receiving space and includes a first mounting portion and a second mounting portion which are spaced apart from each other;

[0007] A lens connected to the first mounting portion;

[0008] An image sensor connected to the second mounting portion;

[0009] A focusing assembly is accommodated in the accommodation space and is disposed between the lens and the image sensor along the optical path. The focusing assembly includes a prism, a driving element, a first light absorbing member and a second light absorbing member. The prism includes a light-transmitting surface, a first light-reflecting surface and a second light-reflecting surface. The light-transmitting surface is used to receive the light collected by the lens, so that the light is reflected by the first light-reflecting surface and the second light-reflecting surface to be emitted from the light-transmitting surface to the image sensor.

[0010] The driving element is used to drive the prism to move along the optical axis direction of the lens;

[0011] The first light absorbing member is disposed on the first light reflecting surface and is used for absorbing stray light emitted to the first light reflecting surface. The second light absorbing member is disposed on the second light reflecting surface and is used for absorbing stray light emitted to the second light reflecting surface.

[0012] On the other hand, the present application provides an electronic device, comprising a housing and a camera module as described above, wherein the camera module is arranged in the housing.

[0013] In the camera module and electronic equipment of the present application, the focusing component is independent of the lens setting, and focusing can be achieved without moving the lens. In the focusing component, a driving element is used to drive the prism to move along the optical axis of the lens in the receiving space of the shell, and the prism has a light-transmitting surface, a first light-reflecting surface and a second light-reflecting surface. The light-transmitting surface is used to receive the light collected by the lens, and reflect through the first light-reflecting surface and the second light-reflecting surface to emit from the light-transmitting surface to the image sensor. In this way, when focusing is performed using the focusing component, the first light-reflecting surface and the second light-reflecting surface change the light propagation path to reduce the movement displacement of the prism relative to the lens, thereby reducing the area of ​​the reflective region provided by the first light-reflecting surface and the second light-reflecting surface for reflecting the light. In this way, when the first light-absorbing member and the second light-absorbing member are used to cover the first light-reflecting surface and the second light-reflecting surface to absorb stray light, the design margin reserved for avoiding the reflective area can be reduced, thereby reducing the stray light entering the image sensor and improving the imaging effect.

[0028] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present application more thorough and comprehensive.

[0038] Combination Figure 1 As shown, in the related art, by configuring a prism 12 in the camera module 10, the light incident from the optical axis of the lens 11 can be reflected to the image sensor 14, thereby obtaining a periscope camera module 20. This camera module 10 is configured in an electronic device, which can reduce the thickness of the electronic device. This use of the prism 12 to adjust the optical path between the lens 11 and the image sensor 14 is usually to set the inclined reflective surface 12a of the prism 12 at a 45° angle between the lens 11 and the image sensor 14, so that the light emitted from the lens 11 is deflected 90 degrees when it enters the prism 12 to enter the image sensor 14. The prism 12 is fixed in the fixing member 10a, and the fixing member 10a is also provided with a driving element 13 for driving the lens 11 to move. The driving element 13 is used to realize that the lens 11 is away from or close to the prism 12, so that the path of the light emitted from the lens 11 entering the image sensor 14 becomes longer or shorter, and then optical zoom is achieved.

[0039] The inventors have found through research that in the related art, when the driving element 13 drives the lens 11 to move along the optical axis to approach or move away from the prism 12, the area of ​​the region where the light is incident on the reflective surface 12 of the prism 12 will change. Figure 2As shown in FIG. 1 , when the lens 11 approaches the prism 12 along the optical axis, so that the distance between the lens 11 and the prism 12 changes from d1 to d2 (d2 is greater than d1), the irradiation area FQ of the reflective surface 12a of the prism 12 by the light from the lens 11 changes to FQ'. Figure 2 It can be seen from the optical path diagram that FQ' is greater than FQ, that is, when the lens 11 is moved so that the lens is away from the prism 12, the area of ​​the region where the light emitted by the lens 11 is incident on the reflective surface 12a of the prism 12 becomes larger. The inventors have found that when such a camera module 10 is used for shooting, the imaging effect is stable when the focal length remains unchanged; however, when the camera module 10 needs to be zoomed, the area of ​​the region where the light is incident on the reflective surface 12a of the prism 12 will be different, and among the light incident on the reflective surface 12a, the light at the edge enters the image sensor 14, causing the imaging effect to deteriorate. For the sake of ease of description, this type of light that enters the image sensor 14 and causes the imaging efficiency to deteriorate is called "stray light". Based on this, when shooting, the stray light entering the image sensor 14 should be reduced as much as possible. However, in the related art, since the area of ​​the reflective surface 12a of the prism 12 where the light emitted by the lens 11 is incident on changes when the lens 11 approaches or moves away from the prism 12, it is difficult to set a structure to block stray light to improve the imaging effect, or the stray light blocking effect is poor and the imaging effect cannot be improved well.

[0040] In order to solve the above-mentioned problem that stray light enters the image sensor and causes the image quality to deteriorate, the inventors have proposed a solution to improve the camera module.

[0041] Combination Figures 3 to 5 As shown, the present application provides a camera module 20, which is used to capture images of a subject and can be provided in an electronic device 100 such as a smart phone, a tablet computer, or an e-reader.

[0042] The camera module 20 of the present application includes a housing 20a, and the housing 20a includes a first mounting portion 201 and a second mounting portion 202 that are spaced apart. The camera module 20 also includes a lens 21, a focusing assembly 22, and an image sensor 23. The lens 21 is connected to the first mounting portion 201, and the image sensor 23 is connected to the second mounting portion 202. The lens 21 can be connected to the first mounting portion 201 through a lens holder 21a, or can be connected to the first mounting portion 201 by a snap-on or threaded connection. The image sensor 23 can be packaged on a circuit board 25, and then connected to the second mounting portion 202 through the circuit board, and the circuit board can be connected to the second mounting portion 202 by glue or screws. It can be understood that the first mounting portion 201 and the second mounting portion 202 provide mounting carriers for the lens 21 and the image sensor 23, so that the housing 20a can support the lens 21 and the image sensor 23. In this embodiment, the circuit board 25 includes but is not limited to a flexible circuit board (FPC) or a printed circuit board (PCB), and the circuit board 25 is used to realize the communication connection between the image sensor 23 and the external circuit, for example, to realize the communication connection between the photosensitive element and the central processing unit or other control chip of the electronic device.

[0043] The housing 20a has a receiving space, and the focusing assembly 22 is received in the receiving space. The focusing assembly 22 is arranged between the lens 21 and the image sensor 23 along the optical path. The lens 21 may include one or more lenses 211 with optical power. The lens 21 can collect incident light and adjust the light to improve the imaging quality of the camera module 20. The number of lenses 211 is not limited here, and can be Figure 3 The three pieces shown can also be Figure 4 The four lenses shown in the figure can also be five or more. The focusing assembly 22 is used to reflect and deflect the light collected by the lens 21 to the image sensor 23, so that the light can be imaged on the image sensor 23. The image sensor 23 includes but is not limited to a charge coupled device (CCD) or a complementary metal oxide semiconductor device (CMOS Sensor).

[0044] Combination Figure 5 and Figure 6 As shown, the focusing assembly 22 includes a prism 221, a driving element, a first light absorbing member 222 and a second light absorbing member 223. The prism 221 includes a light-transmitting surface 221a, a first light-reflecting surface 221b and a second light-reflecting surface 221c. The light-transmitting surface 221a is used to receive the light collected by the lens 21, so that the light can be incident from the light-transmitting surface 221a into the prism 221, and reflected by the first light-reflecting surface 221b and the second light-reflecting surface 221c, so as to be emitted from the light-transmitting surface 221a to the image sensor 23.

[0045] The driving element is used to drive the prism 221 to move along the optical axis of the lens 21 in the receiving space, thereby changing the optical path distance from the lens 21 to the image sensor 23 to achieve optical focusing. The first light absorbing member 222 is disposed on the first reflective surface 221b and is used to absorb stray light emitted to the first reflective surface 221b. The second light absorbing member 223 is disposed on the second reflective surface 221c and is used to absorb stray light emitted to the second reflective surface 221c.

[0046] In the embodiment of the present application, the focus adjustment component 22 is used to achieve focal length adjustment while reducing stray light entering the image sensor 23 as much as possible to improve the imaging quality. Figure 5 and Figure 6 As shown, when focusing is performed using the focusing assembly 22, the prism 221 moves a distance of 1 unit along the optical axis of the lens 21, and the propagation path of the light reflected by the first reflecting surface 221b and the second reflecting surface 221c changes a distance of 2 units. Subsequently, when focusing requires the same focal length change, this structural setting can reduce the movement displacement of the prism 221 relative to the lens 21, thereby reducing the area of ​​the reflective region provided by the first reflecting surface 221b and the second reflecting surface 221c for reflecting light. In this way, when the first light absorbing member 222 and the second light absorbing member 223 are used to cover the area of ​​the first reflecting surface 221b and the second reflecting surface 221c illuminated by stray light to absorb the stray light, the design margin reserved for avoiding the reflective area can be reduced, thereby reducing the stray light entering the image sensor 23 and improving the imaging effect.

[0047] Furthermore, the housing 20 a is provided with an anti-shake module, and the image sensor 23 is connected to the anti-shake module, and the anti-shake module is used to perform anti-shake on the image sensor 23 .

[0048] Since the anti-shake module can realize the movement of the image sensor 23 relative to the housing 20a to realize anti-shake, compared with the related art, which realizes anti-shake by moving the lens 21, under this structure of the present application, the area of ​​the reflective area provided by the first reflective surface 221b and the second reflective surface 221c for reflecting light can be further reduced, so that the first light absorbing member 222 and the second light absorbing member 223 can cover as much area as possible that needs to absorb stray light.

[0049] In some embodiments, the camera module 20 may include a filter element 24, which is disposed between the prism 221 and the image sensor 23. The filter element 24 is used to filter out interference light to prevent the interference light from reaching the image sensor 23 and affecting normal imaging. In some embodiments, the filter element 24 may be an infrared cutoff filter.

[0050] The driving element includes but is not limited to a voice coil motor. In some embodiments, Figure 5 and Figure 6 As shown, the focusing assembly 22 includes a movable seat 22a, a prism 221 is fixed to the movable seat 22a, and a driving element includes a coil 225 and a magnet 226. The coil 225 is connected to the movable seat 22a, and the magnet 226 is connected to the housing 20a. When the coil 225 is energized, it can drive the movable seat 22a to move relative to the housing 20a along the optical axis of the lens 21 in the magnetic field of the magnet 226.

[0051] Furthermore, the camera module 20 also includes a detection component, which is electrically connected to the driving element and is used to feedback the position of the prism 221 relative to the housing 20a to the driving element, and the driving element is used to adjust the position of the prism 221 relative to the housing 20a according to the position fed back by the detection component. Through this feedback adjustment, the focusing speed of the camera module 20 is fast and the focusing accuracy is improved.

[0052] In some embodiments, in combination Figure 5 and Figure 6 As shown, the detection component includes a Hall element 227, which is disposed on the movable seat 22a to move relative to the magnet 226 when the movable seat 22a moves, thereby inducing changes in magnetic field strength in the magnetic field of the magnet 226 to obtain the position of the prism 221 relative to the shell 20a.

[0053] Combination Figure 8 and Fig. 9 As shown, the detection component includes a first pole piece 228 and a second pole piece 229, the first pole piece 228 is connected to the housing 20a, the second pole piece 229 is connected to the movable seat 22a, the first pole piece 228 and the second pole piece 229 are arranged relative to each other to form a capacitor, and the capacitor is configured as follows: when the movable seat 22a drives the prism 221 to move relative to the housing 20a, the area directly facing each other between the first pole piece 228 and the second pole piece 229 changes, and the capacitance value of the capacitor changes. In this way, the current focus position can be known based on the corresponding relationship between the capacitance value of the capacitor and the focus position.

[0054] The structure of the detection component will not be described in detail here.

[0055] In some embodiments, the focusing assembly 22 is configured to be able to deflect the light collected by the lens 21 to the image sensor 23 after at least two reflections. Figure 6 and Figure 7 As shown, the prism 221 is configured such that the light emitted from the lens 21 along the optical axis to the first reflective surface 221b can be incident on the transparent surface 221a and totally reflected from the transparent surface 221a to the second reflective surface 221c. Fig. 9As shown, the prism 221 is configured as follows: the lens 21 emits light along the optical axis to the first reflecting surface 221 b, the first reflecting surface 221 b reflects the light to the second reflecting surface 221 c, and the light is reflected from the transparent surface 221 a by the second reflecting surface 221 c to enter the image sensor 23.

[0056] It should be noted that the lens 21 and the image sensor 23 are located on the same side of the light-transmitting surface 221a, and the direction in which the light collected by the lens 21 exits the lens 21 and the direction in which the light enters the image sensor 23 after passing through the focusing assembly 22 can be parallel to each other or form an acute angle or an obtuse angle. Thus, the lens 21 and the image sensor 23 can be arranged on the same side of the focusing assembly 22 through the deflection effect of the prism 221. Thus, the camera module 20 is arranged in the electronic device, and the lens 21 and the image sensor 23 at least partially overlap in the thickness direction of the electronic device, which is conducive to reducing the size of the camera module 20 in the thickness direction of the electronic device 100. Therefore, on the basis that the lens 21 is independently arranged on the light-entering side of the focusing assembly 22 and can move along the thickness direction of the electronic device under the drive of the driving element, the size of the camera module 20 in the thickness direction of the electronic device will not be too large, which is conducive to reducing the thickness of the electronic device and meeting the assembly requirements of the camera module 20 in the electronic device.

[0057] The optical axis of the lens 21 is perpendicular to the light-transmitting surface 221a, and the image sensor 23 is parallel to the light-transmitting surface 221a. In this arrangement, the alignment and assembly of the lens 21, the focusing assembly 22 and the image sensor 23 are easier, and the assembly accuracy is improved.

[0058] Combine again Figure 3 and Figure 4 As shown, a light blocking member 224 is provided in the prism 221, and the light blocking member 224 is located between the first reflecting surface 221b and the second reflecting surface 221c. The light blocking member 224 is configured to block at least one of the stray light reflected from the first reflecting surface 221b to the transparent surface 221a and the stray light reflected from the transparent surface 221a to the second reflecting surface 221c.

[0059] A groove 2211 is formed on one side of the prism 221 facing away from the light-transmitting surface 221 a , and a light-blocking member 224 is disposed in the groove 2211 to further block stray light and prevent the stray light in the light emitted by the first light-reflecting surface 221 b from being reflected to the image sensor 23 via the second light-reflecting surface 221 c .

[0060] The first light absorbing member 222 is annular and encloses and defines a first light reflecting area on the first light reflecting surface 221 b. The first light reflecting surface 221 b is provided with a first anti-reflection film. The first anti-reflection film covers the first light reflecting area, thereby utilizing the first anti-reflection film to increase the reflectivity of light incident to the first light reflecting area, thereby increasing the amount of light entering the image sensor 23.

[0061] The second light absorbing member 223 is annular and encloses and defines a second light reflecting area on the second light reflecting surface 221c. The second light reflecting surface 221c is provided with a second reflection enhancing film. The second reflection enhancing film covers the second light reflecting area, thereby utilizing the second reflection enhancing film to increase the reflectivity of light incident on the second light reflecting area, thereby increasing the amount of light entering the image sensor 23.

[0062] The first light absorbing member 222 , the second light absorbing member 223 and the light blocking member 224 may be formed on the prism 221 by silk-screen printing or spin coating, or may be formed on the prism 221 by coating.

[0063] Combination Figure 5 and Fig.10 As shown, the present application also provides an electronic device 100, including a housing 101 and a camera module 20 of any of the above embodiments, wherein the camera module 20 is disposed in the housing 101. In some embodiments, the housing 101 is further provided with a light inlet hole, which is disposed corresponding to the light inlet side of the lens 21, so that the lens 21 can collect light. It can be understood that in the related art, the prism 221 is disposed on the light-entering side of the lens 21 in the periscope camera module 20. Since the prism 221 is disposed at the front end of the periscope camera module 20, the light inlet hole of the housing 20a corresponding to the periscope camera module 20 usually needs to be made into a square shape to adapt to the shape of the prism 221, while the light inlets of other camera modules 20 of the electronic device 100 are usually circular, which easily leads to the mismatch of the shapes of the light inlets of the electronic device 100 and affects the appearance of the electronic device 100. The electronic device 100 provided in the present application adopts the camera module 20 of any of the above-mentioned embodiments, and the lens 21 is arranged on the light incident side of the focusing component 22, that is, the lens 21 is located at the front end of the camera module 20. Therefore, the shape of the light inlet hole can be adapted to the shape of the lens 21 to be made into a circular hole, which is easier to adapt to other hole structures of the electronic device 100, thereby achieving the effect of improving the appearance of the electronic device 100.

[0064] refer to Fig.11 , Fig.11 The electronic device 100 is a schematic diagram of the structure of the electronic device 100 provided in the embodiment of the present application. The electronic device 100 may include a radio frequency (RF) circuit 501, a memory 502 including one or more computer-readable storage media, an input unit 503, a display unit 504, a sensor 505, an audio circuit 506, a wireless fidelity (WiFi) module 507, a processor 508 including one or more processing cores, and a power supply 509. Those skilled in the art will understand that Fig.11The structure of the electronic device 100 shown in the figure does not constitute a limitation on the electronic device 100, and may include more or less components than shown in the figure, or combine certain components, or arrange the components differently.

[0065] The radio frequency circuit 501 can be used to send and receive information, or receive and send signals during a call. In particular, after receiving the downlink information of the base station, it is handed over to one or more processors 508 for processing; in addition, the data related to the uplink is sent to the base station. Usually, the radio frequency circuit 501 includes but is not limited to an antenna, at least one amplifier, a tuner, one or more oscillators, a subscriber identity module (SIM) card, a transceiver, a coupler, a low noise amplifier (LNA), a duplexer, etc. In addition, the radio frequency circuit 501 can also communicate with the network and other devices through wireless communication. The wireless communication can use any communication standard or protocol, including but not limited to the global system for mobile communications (GSM), the general packet radio service (GPRS), the code division multiple access (CDMA), the wideband code division multiple access (WCDMA), the long term evolution (LTE), email, the short message service (SMS), etc.

[0066] The memory 502 can be used to store applications and data. The applications stored in the memory 502 contain executable codes. The applications can be composed of various functional modules. The processor 508 executes various functional applications and data processing by running the applications stored in the memory 502. The memory 502 can mainly include a program storage area and a data storage area, wherein the program storage area can store an operating system, an application required for at least one function (such as a sound playback function, an image playback function, etc.), etc.; the data storage area can store data created according to the use of the electronic device 100 (such as audio data, a phone book, etc.), etc. In addition, the memory 502 can include a high-speed random access memory, and can also include a non-volatile memory, such as at least one disk storage device, a flash memory device, or other volatile solid-state storage devices. Accordingly, the memory 502 can also include a memory controller to provide the processor 508 and the input unit 503 with access to the memory 502.

[0067] The input unit 503 can be used to receive input digital, character information or user feature information (such as fingerprints), and generate keyboard, mouse, joystick, optical or trackball signal input related to user settings and function control. Specifically, in a specific embodiment, the input unit 503 may include a touch-sensitive surface and other input devices. The touch-sensitive surface, also known as a touch display screen or a touch pad, can collect user touch operations on or near it (such as operations performed by users using fingers, styluses, or any other suitable objects or accessories on or near the touch-sensitive surface), and drive corresponding connection devices according to a pre-set program. Optionally, the touch-sensitive surface may include a touch detection device and a touch controller. Among them, the touch detection device detects the user's touch orientation, detects the signal brought by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device, converts it into touch point coordinates, and then sends it to the processor 508, and can receive and execute commands sent by the processor 508.

[0068] The display unit 504 can be used to display information input by the user or information provided to the user and various graphical user interfaces of the electronic device 100, which can be composed of graphics, text, icons, videos and any combination thereof. The display unit 504 may include a display panel. Optionally, the display panel can be configured in the form of a liquid crystal display (LCD), an organic light-emitting diode (OLED), or the like. Furthermore, the touch-sensitive surface may cover the display panel, and when the touch-sensitive surface detects a touch operation on or near it, it is transmitted to the processor 508 to determine the type of touch event, and then the processor 508 provides a corresponding visual output on the display panel according to the type of touch event. Although in Fig.11 In the embodiment, the touch sensitive surface and the display panel are used as two independent components to implement input and output functions, but in some embodiments, the touch sensitive surface and the display panel can be integrated to implement input and output functions. It can be understood that the display screen can include an input unit 503 and a display unit 504.

[0069] The electronic device 100 may also include at least one sensor 505, such as a light sensor, a motion sensor, and other sensors.

As a type of motion sensor, the gravity acceleration sensor can detect the magnitude of acceleration in each direction (generally three axes), and can detect the magnitude and direction of gravity when stationary. It can be used for applications that identify the posture of the mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc.; as for other sensors such as gyroscopes, barometers, hygrometers, thermometers, infrared sensors, etc. that can also be configured in the electronic device 100, they will not be repeated here.

[0070] The audio circuit 506 can provide an audio interface between the user and the electronic device 100 through a speaker and a microphone. The audio circuit 506 can convert the received audio data into an electrical signal, transmit it to the speaker, and convert it into a sound signal for output; on the other hand, the microphone converts the collected sound signal into an electrical signal, which is received by the audio circuit 506 and converted into audio data, and then the audio data is output to the processor 508 for processing, and then sent to another electronic device 100 through the radio frequency circuit 501, or the audio data is output to the memory 502 for further processing. The audio circuit 506 may also include an earphone socket to provide communication between an external earphone and the electronic device 100.

[0071] Wireless Fidelity (WiFi) is a short-range wireless transmission technology. The electronic device 100 can help users send and receive emails, browse web pages, and access streaming media through the wireless fidelity module 507, which provides users with wireless broadband Internet access. Fig.11 The wireless fidelity module 507 is shown, but it is understandable that it is not a necessary component of the electronic device 100 and can be omitted as needed without changing the essence of the invention.

[0072] The processor 508 is the control center of the electronic device 100. It uses various interfaces and lines to connect various parts of the entire electronic device 100. By running or executing applications stored in the memory 502 and calling data stored in the memory 502, it executes various functions of the electronic device 100 and processes data, thereby monitoring the electronic device 100 as a whole. Optionally, the processor 508 may include one or more processing cores; preferably, the processor 508 may integrate an application processor and a modem processor, wherein the application processor mainly processes the operating system, user interface, and application programs, and the modem processor mainly processes wireless communications. It is understandable that the above-mentioned modem processor may not be integrated into the processor 508.

[0073] The electronic device 100 also includes a power supply 509 for supplying power to various components. Preferably, the power supply 509 can be logically connected to the processor 508 through a power management system, so that the power management system can manage charging, discharging, and power consumption management. The power supply 509 can also include one or more DC or AC power supplies, recharging systems, power failure detection circuits, power converters or inverters, power status indicators, and other arbitrary components.
