[0009] The first driving mechanism includes a first driving motor, which is disposed on the base frame and connected to the first substrate. The first driving motor drives the first substrate to move, thereby driving the second substrate and the photosensitive chip to move in the first direction;

[0010] The second driving mechanism includes a second driving motor, which is disposed on the base frame or the first substrate and connected to the second substrate. The second driving motor can move the photosensitive chip in a second direction by driving the second substrate.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0019] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here. In addition, the "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally represents that the objects associated with each other are in an "or" relationship.

[0020] The camera module provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0021] Please refer to Figure 1 to Figure 3 The embodiment of the present application discloses a camera module, which includes a base frame 100, a lens, a photosensitive chip 200, a first substrate 300, a first driving mechanism 510, a first guide column 610, a second substrate 400, a second guide column 620 and a second driving mechanism 520.

[0022] The base frame 100 provides a mounting base for other components of the camera module. The first guide post 610 is disposed on the base frame 100. At this time, the first guide post 610 is fixed on the base frame 100. The first substrate 300 is movably connected to the first guide post 610, and the first substrate 300 can move along the extension direction of the first guide post 610, that is, the first substrate 300 moves relative to the base frame 100 along the extension direction of the first guide post 610.

[0023] The second guide pillars 620 are disposed on the first substrate 300, that is, the second guide pillars 620 are fixed on the first substrate 300. The second substrate 400 is movably connected to the first guide pillars 610, and the second substrate 400 moves along the extension direction of the second guide pillars 620. In other words, the second substrate 400 moves relative to the first substrate 300 along the extension direction of the second guide pillars 620.

[0024] The photosensitive chip 200 is disposed on the second substrate 400. Optionally, the photosensitive chip 200 can be bonded to the second substrate 400, and of course, can also be connected to the second substrate 400 in other ways, which is not limited herein.

[0025] The lens is arranged on the base frame 100, and the photosensitive chip 200 is opposite to the lens. The photosensitive chip 200 can be electrically connected to the mainboard of the electronic device through a flexible circuit board. At this time, external light is incident on the photosensitive chip 200 through the lens, and the photosensitive chip 200 converts the light signal into an electrical signal and transmits it to the mainboard, thereby realizing the shooting function of the camera module.

[0026] The first driving mechanism 510 includes a first driving motor 511, which is disposed on the base frame 100 and connected to the first substrate 300. The first driving motor 511 drives the first substrate 300 to move, thereby driving the second substrate 400 and the photosensitive chip 200 to move in the first direction. The first direction here is parallel to the extension direction of the first guide column 610, and it can also be understood that the first direction is the extension direction of the first guide column 610.

[0027] The second driving mechanism 520 includes a second driving motor 521, which is disposed on the base frame 100 or the first substrate 300 and connected to the second substrate 400. The second driving motor 521 can move the photosensitive chip 200 in the second direction by driving the second substrate 400. The second direction here is parallel to the extension direction of the second guide column 620, and it can also be understood that the second direction is the extension direction of the second guide column 620.

[0028] In the embodiment disclosed in the present application, since the second substrate 400 is movably connected to the first substrate 300 through the second guide column 620, when the first drive motor 511 drives the first substrate 300 to move, the first substrate 300 can drive the second substrate 400 and the photosensitive chip 200 to move together. In addition, the second substrate 400 is movably connected to the second guide column 620, and the second substrate 400 and the first substrate 300 can also move relatively, and then when the second drive motor 521 drives the second substrate 400 to move, the second substrate 400 can also drive the photosensitive chip 200 to move alone. Both the first substrate 300 and the second substrate 400 can drive the photosensitive chip 200 to move, so that the jitter of the camera module can be compensated, and then the anti-shake function can be realized to improve the image capture quality of the electronic device.

[0029] In addition, the first guide column 610 has a guiding function on the first substrate 300, and the second guide column 620 has a guiding function on the second substrate 400. Therefore, the first guide column 610 and the second guide column 620 can guide and limit the moving direction of the photosensitive chip 200, thereby improving the moving accuracy of the photosensitive chip 200 and preventing the photosensitive chip 200 from tilting or shifting during the movement, thereby making the anti-shake performance of the camera module better.

[0030] In addition, the first substrate 300 and the second substrate 400 can both move, so the first substrate 300 and the second substrate 400 are not likely to affect each other, thereby being able to achieve independent movement in two directions, thereby enabling the camera module to achieve compensation in two directions to increase the anti-shake compensation range of the camera module.

[0031] In the embodiment disclosed in the present application, the driving of the first substrate 300 and the driving of the second substrate 400 both use a driving motor as a power source. Compared with the electromagnetic driving method, the driving motor will not cause magnetization of components on the photosensitive chip 200, thereby improving the safety performance of the camera module.

[0032] During the specific anti-shake process of the above-mentioned camera module, when the gyroscope inside the electronic device or the camera module detects that the camera module is tilted, the gyroscope will transmit data such as the tilt angle of the camera module to the control chip. The control chip inputs the corresponding angle compensation amount. The control chip controls the movement of the first substrate 300 and the second substrate 400 through the first driving mechanism 510 and the second driving mechanism 520. The first substrate 300 and the second substrate 400 drive the photosensitive chip 200 to move to achieve angle compensation, thereby realizing the anti-shake function of the camera module.

[0033] The first guide pillar 610 in the above embodiment can be welded to the base frame 100. Of course, the first guide pillar 610 can also be connected to the base frame 100 in other ways, which is not limited herein. The connection method of the second guide pillar 620 and the first substrate 300 can be the same as the connection method of the first guide pillar 610 and the base frame 100.

[0034] In the above embodiment, the second drive motor 521 can be arranged on the base frame 100, or can be arranged on the first substrate 300. When the second drive motor 521 is arranged on the first substrate 300, the first substrate 300 also drives the second drive motor 521 to move. When the second drive motor 521 is arranged on the base frame 100, the second drive motor 521 and the second substrate 400 need to avoid along the moving direction of the first substrate 300, so as to avoid the situation that the first substrate 300 cannot move. The specific structure of the second drive motor 521 arranged on the base frame 100 is described in detail below, and will not be repeated here.

[0035] Optionally, the extension direction of the first guide pillar 610 and the extension direction of the second guide pillar 620 can be parallel, that is, the moving direction of the first substrate 300 is the same as the moving direction of the second substrate 400, so the first direction and the second direction are the same. This scheme can increase the compensation range of the jitter amount of the photosensitive chip 200 in the same direction.

[0036] Of course, the extension direction of the first guide pillar 610 may intersect with the extension direction of the second guide pillar 620, which is actually the first direction intersecting with the second direction. At this time, the extension direction of at least one of the first guide pillar 610 and the second guide pillar 620 may be along the length direction or width direction of the photosensitive chip 200, and the extension direction of the other may be along the thickness direction of the photosensitive chip 200, that is, the extension direction of the other may be perpendicular to the photosensitive surface of the photosensitive chip 200. At this time, the guide pillar perpendicular to the photosensitive surface of the photosensitive chip 200 is used to realize the focusing function of the photosensitive chip 200.

[0037] In another optional embodiment, the extension direction of the first guide pillar 610 and the extension direction of the second guide pillar 620 may intersect, and the plane where the first guide pillar 610 and the second guide pillar 620 are located may be parallel to the plane where the photosensitive chip 200 is located. In this solution, the photosensitive chip 200 can move along the plane where it is located, so that the photosensitive chip 200 can move in two different directions, further improving the anti-shake range of the photosensitive chip 200.

[0038] Furthermore, the extension direction of the first guide pillar 610 and the extension direction of the second guide pillar 620 may be perpendicular to each other. In this case, the extension direction of the first guide pillar 610 may be parallel to the length direction of the photosensitive chip 200. The extension direction of the second guide pillar 620 may be parallel to the width direction of the photosensitive chip 200.

[0039] In the above embodiment, the first driving mechanism 510 may further include a first transmission member, and the first driving motor 511 is connected to the first substrate 300 by driving through the first transmission member. Optionally, the first driving mechanism 510 may include a first screw 512, and the first driving motor 511 may be threadedly connected to the first substrate 300 through the first screw 512, and the movement of the first substrate 300 is achieved by the rotation of the first screw 512. However, since the force-bearing area of ​​the first screw 512 on the first substrate 300 is small, it is easy to cause the first substrate 300 to be subjected to force only on one side, resulting in uneven force on the first substrate 300, causing the first substrate 300 to tilt when moving.

[0040] Based on this, in another optional embodiment, the first transmission member may further include a first drive plate 513 and a first elastic member 515, the first screw 512 may be connected to the first drive motor 511, the first substrate 300 may be provided with a first through hole, the first screw 512 may pass through the first through hole and be threadedly connected to the first drive plate 513, the first drive plate 513 may contact the first substrate 300, and the first drive motor 511 may drive the first substrate 300 to move through the first screw 512 and the first drive plate 513. One end of the first elastic member 515 may be connected to the base frame 100, and the other end of the first elastic member 515 may be connected to the first substrate 300, and the telescopic direction of the first elastic member 515 is parallel to the extension direction of the first guide column 610.

[0041] During the specific operation, when the camera module performs an anti-shake operation, the first drive motor 511 drives the first screw 512 to rotate, and the first screw 512 drives the first drive plate 513 to move, and the first drive plate 513 contacts the first substrate 300. At this time, the first elastic member 515 is compressed, and the first drive plate 513 can drive the first substrate 300 to move along its moving direction to achieve anti-shake. When the first substrate 300 returns to its original position, the first drive motor 511 drives the first screw 512 to rotate in the opposite direction, so that the first drive plate 513 removes the force acting on the first substrate 300, and the first elastic member 515 restores elastic deformation, thereby driving the first substrate 300 to return to its original position, where the original position is the position of the photosensitive chip 200 before the anti-shake operation occurs.

[0042] In this solution, the first driving plate 513 contacts the first substrate 300 . At this time, the contact area between the first driving plate 513 and the first substrate 300 is large, so that the force on the first substrate 300 is more balanced, and the first substrate 300 is not easy to tilt when moving.

[0043] In the above embodiment, in order to prevent the first screw 512 from driving the first drive plate 513 to rotate, the gravity of the first drive plate 513 itself should be greater than the friction between the first drive plate 513 and the first screw 512. At this time, the first screw 512 can only drive the first drive plate 513 to move, and will not drive the first drive plate 513 to rotate together.

[0044] Optionally, the first elastic member 515 may be a spring, or other elastic members, which is not limited herein.

[0045] In another optional embodiment, the first substrate 300 may include a first plate body 310 and a first extension portion 320 extending from a side of the first plate body 310 away from the base frame 100, the first guide column 610 is movably connected to the first plate body 310, the first through hole may be opened in the first extension portion 320, and the first driving plate 513 is in contact with the first extension portion 320.

[0046] In this solution, the first plate body 310 is used to connect with the first guide pillar 610, so the area of ​​the first plate body 310 is relatively large, and is used to provide installation space for the second substrate 400. The first extension portion 320 is used to contact with the first driving plate 513, so its volume can be set to be relatively small, so that the structure of the first substrate 300 is relatively simple and compact.

[0047] In the above embodiment, the first extension portion 320 and the first driving plate 513 are too tightly attached to each other, which may easily cause the first extension portion 320 and the first driving plate 513 to be adhered to each other.

[0048] In another optional embodiment, the first extension portion 320 may be provided with a first protrusion 321 on one side facing the first driving plate 513, and the first driving plate 513 may contact the first protrusion 321; or, the first driving plate 513 may be provided with a first protrusion 321 on one side facing the first extension portion 320, and the first extension portion 320 may contact the first protrusion 321. In this solution, the first protrusion 321 can form a certain gap between the first extension portion 320 and the first driving plate 513, thereby preventing the first extension portion 320 from being too tightly attached to the first driving plate 513, causing the first extension portion 320 to adhere to the first driving plate 513.

[0049] In another optional embodiment, the number of the first guide pillars 610 may be at least two, and the at least two first guide pillars 610 may be respectively located on opposite sides of the first plate body 310, and the extension directions of the at least two first guide pillars 610 are parallel. In this solution, the first guide pillars 610 are disposed on both sides of the first substrate 300, so the first guide pillars 610 on both sides can evenly support the first substrate 300, thereby preventing the first substrate 300 from tilting to one side during movement, thereby further improving the anti-shake performance of the camera module.

[0050] In another optional embodiment, the number of the first elastic members 515 is at least two, and at least one first elastic member 515 can be mounted on the first guide column 610. In this solution, at least one first elastic member 515 can be mounted on the first guide column 610, and the installation space of the first elastic member 515 can be compressed on the base frame 100, thereby optimizing the structure of the camera module.

[0051] In another optional embodiment, the first plate body 310 has a first side and a second side that are arranged opposite to each other, the first side may be provided with a first clamping portion 311, and the second side may be provided with a first guide hole that penetrates the first plate body 310. Among them, one first guide post 610 is clamped and connected with the first clamping portion 311, and the other first guide post 610 can be mounted in the first guide hole. In this scheme, the first clamping portion 311 is an open structure, so it can be directly clamped on the first guide post 610. In the specific assembly process, one of the first guide posts 610 can be firstly mounted in the first guide hole, and then after the other parts and the first guide post 610 on the base frame 100 are installed, the first guide post 610 on the other side is clamped into the first clamping portion 311, so that the first substrate 300 will not affect the installation of other parts of the base frame 100, thereby making the installation of the camera module less difficult.

[0052] In another optional embodiment, one of the first elastic members 515 can be mounted on the first guide column 610 corresponding to the first clamping portion 311, and one end of the first elastic member 515 is connected to the first clamping portion 311. In this solution, since the first clamping portion 311 protrudes from the first plate body 310, its volume can be set smaller, so a larger installation position can be reserved for the first elastic member 515 on the first guide column 610, so that the length of the first guide column 610 can be set shorter, thereby making the overall volume of the camera module smaller.

[0053] In another optional embodiment, the first transmission member also includes a first gear set 514, and the first drive motor 511 and the first screw rod 512 can be connected through the first gear set 514, and the first drive motor 511 can drive the first screw rod 512 to rotate through the first gear set 514. In this solution, the transmission direction of the power of the first drive motor 511 can be changed through the first gear set 514, so that the arrangement of the first drive mechanism 510 and the first substrate 300 is more flexible. In addition, by changing the diameter of the gear in the first gear set 514, the moving speed of the first substrate 300 can be increased or reduced, thereby meeting the anti-shake requirements of the camera module.

[0054] In the above embodiment, the base frame 100 is provided with a first supporting protrusion, and the first supporting protrusion is used to support the first screw rod 512, and the first screw rod 512 can rotate relative to the first supporting protrusion.

[0055] In the above embodiment, the second driving motor 521 can be disposed on the first substrate 300 . When the first substrate 300 moves, the second driving motor 521 is driven to move, thereby increasing the weight of the first substrate 300 , which can easily affect the moving speed of the first substrate 300 .

[0056] Based on this, in another optional embodiment, the second drive motor 521 can be disposed on the base frame 100. The second drive mechanism 520 can also include a second transmission member, the second transmission member includes a second screw 522, a second drive plate 523 and a second elastic member 525, the second substrate 400 can be provided with a second through hole, the second screw 522 can pass through the second through hole and be threadedly connected with the second drive plate 523, the second drive plate 523 can contact the second substrate 400, and the second drive motor 521 can drive the second substrate 400 to move through the second screw 522 and the second drive plate 523.

[0057] The second screw rod 522 can move relative to the second through hole along the extending direction of the first guide pillar.

[0058] One end of the second elastic member 525 is connected to the base frame 100 and / or the first substrate 300 , and the other end of the second elastic member 525 can be connected to the second substrate 400 . The extension direction of the second elastic member 525 can be parallel to the extension direction of the second guide column 620 .

[0059] In this solution, the second driving motor 521 is disposed on the base frame 100 , so the weight of the first substrate 300 is relatively small, thereby increasing the moving speed of the first substrate 300 .

[0060] In this embodiment, the second screw rod 522 can move relative to the second through hole along the extension direction of the first guide pillar. During the movement of the first substrate 300, the second substrate 400 can avoid the second screw rod 522 through the second through hole, so that the second substrate 400 can move together with the first substrate 300, thereby avoiding the first substrate 300 from being stuck.

[0061] In the specific operation process, when the camera module performs an anti-shake operation, the second drive motor 521 drives the second screw 522 to rotate, and the second screw 522 drives the second drive plate 523 to move, and the second drive plate 523 contacts the second substrate 400. At this time, the second elastic member 525 is compressed, and the second drive plate 523 can drive the second substrate 400 to move along its moving direction, thereby achieving anti-shake. When the second substrate 400 returns to its original position, the second drive motor 521 drives the second screw 522 to rotate in the opposite direction, so that the second drive plate 523 removes the force acting on the second substrate 400, and the second elastic member 525 restores elastic deformation, thereby driving the second substrate 400 to return to its original position, where the original position refers to the position of the photosensitive chip 200 before the anti-shake operation occurs.

[0062] In the above embodiment, the second driving plate 523 contacts the second substrate 400 . At this time, the contact area between the second driving plate 523 and the second substrate 400 is large, so that the force on the second substrate 400 is more balanced, and the second substrate 400 is not easy to tilt when moving.

[0063] In the above embodiment, in order to prevent the second screw 522 from driving the second drive plate 523 to rotate, the gravity of the second drive plate 523 itself should be greater than the friction between the second drive plate 523 and the second screw 522. At this time, the second screw 522 can only drive the second drive plate 523 to move, and will not drive the second drive plate 523 to rotate together.

[0064] Optionally, the second elastic member 525 may be a spring, or other elastic members, which is not limited herein. The second through hole may be a strip hole, and the extending direction of the strip hole may be the same as the extending direction of the first guide pillar 610 .

[0065] In another optional embodiment, the second substrate 400 may include a second plate body 410 and a second extension portion 420 extending from a side of the second plate body 410 away from the base frame 100, and the second guide column 620 may be movably connected to the second plate body 410. The second through hole may be provided in the second extension portion 420, and the second driving plate 523 may contact the second extension portion 420. In this solution, the second plate body 410 is used to connect with the second guide column 620, so the area of ​​the second plate body 410 is relatively large, which is used to provide an installation space for the photosensitive chip 200, and the second extension portion 420 is used to contact with the second driving plate 523, so its volume can be set to be relatively small, so that the structure of the second substrate 400 is relatively simple and compact.

[0066] In the above embodiment, the second extension portion 420 and the second driving plate 523 can slide relative to each other along the extension direction of the first guide column 610. The first extension portion 320 and the second driving plate 523 are too tightly fitted, which can easily cause excessive friction between the second extension portion 420 and the second driving plate 523, thereby affecting the speed at which the first substrate 300 and the second substrate 400 move along the extension direction of the first guide column 610, thereby affecting the anti-shake performance of the camera module.

[0067] Based on this, in another optional embodiment, a second protrusion 421 is provided on one side of the second extension portion 420 facing the second driving plate 523, and the second driving plate 523 can contact the second protrusion 421. In this solution, the second protrusion 421 can reduce the contact surface area between the second driving plate 523 and the second extension portion 420, thereby reducing the friction between the second extension portion 420 and the second driving plate 523, so that the second extension portion 420 and the second driving plate 523 are easy to slide relative to each other, and thus it is not easy to affect the speed at which the first substrate 300 and the second substrate 400 move along the extension direction of the first guide column 610, so as to improve the anti-shake performance of the camera module.

[0068] Alternatively, in another optional embodiment, a second protrusion 421 may be provided on one side of the second driving plate 523 facing the second extension portion 420, and the second extension portion 420 may contact the second protrusion 421. The effect achieved by this solution is the same as that of the above solution, and will not be described in detail herein.

[0069] In addition, in the above two solutions, the second protrusion 421 can form a certain gap between the second extension part 420 and the second driving plate 523, thereby preventing the second extension part 420 and the second driving plate 523 from being too tightly fitted and causing the second extension part 420 and the second driving plate 523 to adhere to each other.

[0070] In another optional embodiment, the number of the second guide pillars 620 may be at least two, and the at least two second guide pillars 620 may be respectively located on opposite sides of the second plate body 410, and the extension directions of the at least two second guide pillars 620 are parallel. In this solution, the second guide pillars 620 are disposed on both sides of the second substrate 400, so the second guide pillars 620 on both sides can evenly support the second substrate 400, thereby preventing the second substrate 400 from tilting to one side during movement, thereby further improving the anti-shake performance of the camera module.

[0071] In another solution, the number of the second elastic members 525 may be at least two, and at least one second elastic member 525 may be mounted on the second guide column 620. In this solution, at least one second elastic member 525 is mounted on the second guide column 620, and the installation space of the second elastic member 525 can be compressed on the base frame 100 or the first substrate 300, thereby optimizing the structure of the camera module.

[0072] In another optional embodiment, the second plate body 410 may have a third side and a fourth side disposed opposite to each other, the third side may be provided with a second clamping portion 411, and the fourth side may be provided with a second guide hole that penetrates the second plate body 410. One of the second guide posts 620 may be clamped and connected with the second clamping portion 411, and the other second guide post 620 may be fitted into the second guide hole. In this solution, the second clamping portion 411 is an open structure, so it can be directly clamped on the second guide post 620. In the specific assembly process, one of the second guide posts 620 may be first fitted into the second guide hole, and then after the other components and the second guide posts 620 on the base frame 100 are installed, the second guide post 620 on the other side is clamped into the second clamping portion 411, so that the second substrate 400 will not affect the installation of other components of the base frame 100, thereby making the installation of the camera module less difficult.

[0073] In another optional embodiment, one end of one of the second elastic members 525 can be connected to the base frame 100, and the other end can be connected to the second substrate 400. Another second elastic member 525 can be mounted on the second guide column 620 corresponding to the second clamping portion 411, and one end can be connected to the first substrate 300, and the other end can be connected to the second clamping portion 411. In this solution, since the second clamping portion 411 protrudes from the second plate body 410, its volume can be set smaller, so the installation of the second elastic member 525 on the second guide column 620 can reserve a larger position, so that the length of the second guide column 620 can be set shorter, thereby making the overall volume of the camera module smaller.

[0074] In another optional embodiment, the second transmission member may further include a second gear set 524, the second drive motor 521 may be connected to the second screw rod 522 via the second gear set 524, and the second drive motor 521 may drive the second screw rod 522 to rotate via the second gear set 524. In this solution, the transmission direction of the power of the second drive motor 521 can be changed by the second gear set 524, so that the setting positions of the second drive mechanism 520 and the second substrate 400 are more flexible. In addition, by changing the diameter of the gears in the second gear set 524, the moving speed of the second substrate 400 can be increased or decreased, thereby meeting the anti-shake requirements of the camera module.

[0075] In the above embodiment, the base frame 100 is provided with a second supporting protrusion, and the second supporting protrusion is used to support the second screw rod 522, and the second screw rod 522 can rotate relative to the second supporting protrusion.

[0076] In another optional embodiment, the first substrate 300 may be provided with an escape notch, and part of the second substrate 400 may be located in the escape notch. This solution can reduce the stacking height of the first substrate 300 and the second substrate 400, thereby facilitating the development of a thinner and lighter camera module.

[0077] Furthermore, the second substrate 400 may be provided with an avoidance hole, and at least a portion of the photosensitive chip 200 may be located in the avoidance hole, thereby further reducing the volume of the camera module.

[0078] In the embodiment disclosed in the present application, the base frame 100 may include a base and a top plate. Figure 1 The part in the figure is only the part of the base frame 100, that is, the base, and the top plate is not shown. At this time, the first guide column 610 can be arranged on the base, and the lens can be arranged on the top plate.

[0079] In another optional embodiment, the camera module disclosed in the present application may further include at least one detection element, which may be disposed on the base frame 100, and the detection element may be used to detect the offset angle of the lens relative to the photosensitive chip 200. In this solution, the detection element may measure the offset angle of the photosensitive chip 200 in real time, thereby ensuring the anti-shake effect of the camera module. Optionally, the detection element may be a Hall chip, and of course, may also be other types of chips, which are not limited herein.

[0080] During a specific operation, when the photosensitive chip 200 moves, the detection element can detect the offset angle of the photosensitive chip 200 , and the detection signal can be fed back to the control chip, thereby correcting the offset position of the photosensitive chip 200 .

[0081] Based on the camera module disclosed in the embodiments of the present application, the embodiments of the present application also disclose an electronic device, and the disclosed electronic device includes the camera module described in any of the above embodiments.

[0082] The electronic device disclosed in the embodiments of the present application may be a smart phone, a tablet computer, an e-book reader, a wearable device (such as a smart watch), an electronic game console, or the like. The embodiments of the present application do not limit the specific types of electronic devices.

[0083] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
