Please refer to FIG. 2 . FIG. 2 is a schematic structural diagram of the camera module in the electronic device shown in FIG. 1 . The camera module 20 may include a lens 100 , a photosensitive element 200 , a first bracket 300 , a first driving motor 400 and a second driving motor 500 . Wherein, the first bracket 300 has a first side and a second side disposed opposite to each other, the first driving motor 400 is disposed on the first side, and the second driving motor 500 is disposed on the second side. It can be understood that, the first driving motor 400 and the second driving motor 500 are arranged on the same support at the same time, and are respectively located on opposite sides of the first support 300 . Compared with the related art, setting the first driving motor 400 and the second driving motor 500 on different brackets can save one bracket and simplify the structure of the camera module 20 .

The lens 100 is arranged on the first driving motor 400 , and the lens 100 can be driven to move by the first driving motor 400 to achieve anti-shake of the lens 100 . Wherein, the material of the lens 100 may be glass or plastic. The lens 100 is mainly used to change the propagation path of light and focus the light. The lens 100 may include multiple groups of lenses, and the multiple groups of lenses will mutually correct and filter light.

The photosensitive element 200 may specifically be an image sensor such as a CCD (Charge Coupled Device, Charge Coupled Device), or an image sensor such as a CMOS (Complementary Metal Oxide Semiconductor, Complementary Metal Oxide Semiconductor). The photosensitive element 200 can be arranged opposite to the lens 100 in the direction of the optical axis of the camera module 20 (that is, the direction of the optical axis of the lens 100, as shown by the dashed line in FIG. 2 ), and is mainly used to receive light collected by the lens 100 and The optical signal is converted into an electrical signal, so as to realize the imaging requirement of the camera module 20 . The photosensitive element 200 is arranged on the second driving motor 500 , and the photosensitive element 200 can be driven to move by the second driving motor 500 so as to realize anti-shake of the photosensitive element 200 of the camera module 20 .

It can be understood that, the first driving motor 400 and the second driving motor 500 are mainly used to improve the imaging effect of the camera module 20 caused by shaking of the user during use, so that the imaging effect of the photosensitive element 200 can meet the user's requirements. Usage requirements. The camera module 20 of the embodiment of the present application can not only realize the anti-shake of the lens 100, but also realize the anti-shake of the photosensitive element 200, that is, the camera module 20 of the embodiment of the present application has dual anti-shake functions.

In related technologies, usually only a single anti-shake function such as camera anti-shake or photosensitive chip anti-shake can be realized. However, the single anti-shake structure such as camera anti-shake or photosensitive chip anti-shake is limited by the structural space of the electronic device. Limited, only small angles (such as within 1° or within 1.5°) of the optical image stabilization function can be realized. The camera module 20 of the embodiment of the present application can realize the anti-shake of the lens 100 and the anti-shake of the photosensitive element 200 at the same time, integrate the anti-shake function of the lens 100 and the anti-shake function of the photosensitive element 200, and can realize optical anti-shake at a larger angle compared with related technologies , effectively improving the optical image stabilization effect of the camera module 20 .

The second driving motor 500 can also adopt one of electromagnetic motor, piezoelectric motor, memory alloy driver and micro-electromechanical system, and the type adopted by the second driving motor 500 can be the same as that adopted by the first driving motor 400. The same type, for example, both use electromagnetic motors, or both use piezoelectric motors. Certainly, the type adopted by the second driving motor 500 may be different from that adopted by the first driving motor 400. For example, the first driving motor 400 may adopt an electromagnetic motor, and the second driving motor 500 may adopt a memory alloy driver and a micro-electromechanical motor. System (Micro-Electro-Mechanical System, MEMS).

Since there are two drive motors such as the first drive motor 400 and the second drive motor 500 in the camera module 20, two drive chips need to be set in the camera module 20 for the first drive motor 400 and the second drive motor 500 respectively. for separate control.

As shown in FIG. 3 , FIG. 3 is a schematic structural diagram of a first type of dual anti-shake system provided in an embodiment of the present application. The dual anti-shake system 2000 may include the camera module 20 and the detection module 40 as described in the embodiment of the above application. The detection module 40 can collect shaking data of the camera module 20 .

Exemplarily, the detection module 40 may be any angular motion detection device that detects angular velocity, such as a gyroscope. During the process of capturing images by the camera module 20, if the camera module 20 shakes or moves, it will affect the clarity of the imaging, making the collected images blurred. The gyroscope can detect whether the camera module 20 shakes, and obtain the angular velocity information of the camera module 20 when the camera module 20 shakes, so as to obtain the shake data of the camera module 20 .

As shown in FIG. 3 , the camera module 20 can also include at least two driver chips. For example, the camera module 20 can include a first driver chip 600 and a second driver chip 700. The first driver chip 600 responds to the camera module 20. Shake the data to obtain the first shake compensation data and the second shake compensation data, and control the movement of one of the lens 100 and the photosensitive element 200 according to the first shake compensation data, the second driver chip 700 responds to the second shake compensation data, and Another movement of the lens 100 and the photosensitive element 200 is controlled. Exemplarily, the first driving chip 600 may be connected with the lens 100 , and the second driving chip 700 may be connected with the photosensitive element 200 . Wherein, the connection in this embodiment of the present application may be a direct connection, may be an indirect connection through other devices, or may be a wireless connection. For example, the first drive chip 600 can be connected to the lens 100 through the first drive motor 400, the first drive chip 600 can control the lens 100 by controlling the first drive motor 400, and the second drive chip 700 can be connected to the lens 100 through the second drive motor 500. The photosensitive element 200 is connected, and the second driving chip 700 can control the photosensitive element 200 by controlling the second driving motor 500 .

It should be noted that the camera module 20 may also include three driver chips, four driver chips or other values of driver chips.

Wherein, the detection module 40 can be connected with the first driving chip 400 . The detection module 40 can collect the shake data of the camera module 20, and send the shake data of the camera module 20 to the first driver chip 600, and the first driver chip 600 can process the shake data of the camera module 20 to obtain the second a shake compensation data and second shake compensation data, and control the movement of the lens 100 according to the first shake compensation data and send the second shake compensation data to the second driving chip 700 .

The detection module 40 may send the shaking data of the camera module 20 to the first driver chip, for example, send the detected angular velocity information to the first driver chip 600 . The first drive chip 600 can obtain the current position information of the lens 100 through the built-in Hall sensor, and when receiving the angular velocity information, calculate the shake compensation information of the lens 100 according to the angular velocity information to obtain the first shake compensation data, based on the position information and The first shake compensation data controls the operation of the first driving motor 400 , and then drives the lens 100 to move through the first driving motor 400 , and the moving direction of the lens 100 is opposite to the shaking direction. Specifically, the current position information of the lens 100 is the offset of the lens 100 relative to the initial position, and the first shake compensation data is the shake compensation amount of the lens 100 in different directions or that the lens 100 needs to move in order to reduce the deviation caused by the shake. The first driving chip 600 can determine the target position information of the lens 100 according to the current position information of the lens 100 and the first shake compensation data.

For example, with the center of the initial position of the lens 100 as the origin, the plane where the lens 100 is located establishes an XY axis coordinate system, assuming that the current position information of the lens 100 is (2, 3), the first jitter calculated by the first driver chip 600 If the compensation data is (-1, -2), then according to the current position information and the first shake compensation data, it can be determined that the target position information is (1, 1). At this time, the first drive chip 600 can control the first drive motor 400 to drive The lens 100 moves 1 unit length in the X-axis direction and 2 unit lengths in the Y-axis direction, so that the lens 100 is at the target position marked by the target position information (1, 1).

In some other embodiments, the detection module 40 may also be any detection device for detecting acceleration, such as an accelerometer. Of course, the detection module 40 can also be other types of detection devices, as long as it can detect the shake data of the camera module 20 , which is not limited in this embodiment of the present application.

After receiving the second shake compensation data sent by the first drive chip 600 , the second driving chip 700 can drive the photosensitive element 200 to move according to the second shake compensation data. For example, the second drive chip 700 can obtain the current position information of the photosensitive element 200 through the built-in Hall sensor, control the second drive motor 500 to work based on the current position information of the photosensitive element 200 and the second shake compensation data, and then pass the second drive motor 500 drives the photosensitive element 200 to move, and the moving direction of the photosensitive element 200 is opposite to the shaking direction, so as to eliminate the deviation of the camera module 20 caused by the shaking from the lens 100 and the photosensitive element 200 . For the specific control process of the photosensitive element 200, reference may be made to the above control process of the lens 100, which will not be repeated here.

It can be understood that the first driver chip 600 can convert the total offset of the camera module 20 into the shake compensation amount of the lens 100 and the shake compensation amount of the photosensitive element 200, and send the shake compensation amount of the photosensitive element 200 to the second The second driver chip 700, with respect to the two driver chips respectively performing calculations according to the shake data of the camera module 20, the first driver chip 600 and the second driver chip 700 in the embodiment of the present application can work together, adding the first driver chip 600 and the connection between the second driver chip 700 .

In the embodiment of the present application, since the specific calculation process of shake compensation is completed by the first driver chip 600, the second driver chip 700 only needs to control the photosensitive element 200 according to the received second shake compensation data without performing calculations. , so the structure of the second driving chip 700 can be simplified. For example, please refer to Fig. 4 and Fig. 5, Fig. 4 is a schematic diagram of the second structure of the dual anti-shake system provided by the embodiment of the present application, and Fig. 5 is the third structure of the dual anti-shake system provided by the embodiment of the present application schematic diagram. The first driver chip 600 may include a first execution module 620 and a first processing module 640, the first processing module 640 is connected to the first execution module 620, the first processing module 640 is also connected to the detection module 40, the first execution module 620 is connected to the lens 100 , and the first drive motor 400 is connected to the first execution module 620 and the lens 100 respectively. The second driving chip 700 may include a second execution module 720, the second execution module 720 is respectively connected with the first processing module 640 and the photosensitive element 200, and the second driving motor 500 is respectively connected with the second execution module 720 and the photosensitive element 200 .

Wherein, the first processing module 640 is mainly responsible for the calculation and processing of various types of data. For example, the first processing module 640 may pre-store a shake compensation algorithm, and use the shake compensation algorithm to process the shake data of the camera module 20 to obtain the above-mentioned first shake compensation data and second shake compensation data. After the first processing module 640 obtains the first shake compensation data and the second shake compensation data, it may send the first shake compensation data to the first execution module 620 and send the second shake compensation data to the second execution module 720 .

The first execution module 620 is mainly responsible for the execution of various operations such as controlling whether the first driving motor 400 works or not, or the specific working state of the first driving motor 400 (such as the control of working parameters) to control the lens 100 . For example, after the first execution module 620 receives the first shake compensation data sent by the first processing module 640, it can obtain the first drive value according to the first shake compensation data, and control the first drive motor 400 according to the first drive value. , so that the first driving motor 400 uses the first driving value to drive the lens 100 to move.

The second execution module 720 is mainly responsible for controlling the photosensitive element 200 for various operations such as controlling whether the second drive motor 500 works or not, or the specific working state of the second drive motor 500 (such as the control of working parameters). For example, after the second execution module 720 receives the second shake compensation data sent by the first processing module 640, it can obtain the second drive value according to the second shake compensation data, and control the second drive motor 500 according to the second drive value. , so that the second driving motor 500 uses the second driving value to control the movement of the photosensitive element 200 .

Specifically, for example, the shake data of the camera module 20 is 2 degrees (which can be understood as the anti-shake angle), and the first shake compensation data calculated by the first processing module 620 is 1 degree (which can be understood as the anti-shake angle of the lens 100). The compensation angle is 1 degree), and the second shake compensation data is also 1 degree, which can be understood as the anti-shake compensation angle of the photosensitive element 200 is 1 degree). The first execution module 620 obtains the first driving value according to the anti-shake angle of 1 degree, such as a current value of 5mA, and controls the first driving motor 400 according to the current value of 5mA, so that the output of the first driving motor 400 can drive the lens 100 Move so that the lens 100 achieves an anti-shake angle of 1 degree. The second execution module 720 controls the second drive motor 500 according to the anti-shake angle of 1 degree, so that the second drive motor 500 can drive the photosensitive element 200 to move so that the photosensitive element 200 realizes the anti-shake angle of 1 degree, and realizes at the same time The anti-shake function of the lens 100 and the dual anti-shake function of the photosensitive element 200 can obtain a larger anti-shake angle.

It can be understood that, since the embodiment of the present application assigns all data processing processes of shake compensation to the first processing module 640 in the first driver chip 600, the second driver chip 700 does not need additional processing modules, and only needs Setting the execution module can simplify the structure of the second driving chip 700 , thereby reducing the manufacturing cost of the second driving chip 700 . Moreover, the two jitter compensation data are processed by one driver chip, which is helpful for the dynamic adjustment of the two jitter compensation data.

In the embodiment of the present application, the first execution module 620 may search for the driving value corresponding to the first shake compensation data according to the first preset mapping relationship to obtain the first driving value. For example, the driving value of the first driving motor 400 and the displacement value of the lens 100 can be tested in advance to determine the corresponding relationship between the driving value of the first driving motor 400 and the displacement value of the lens 100, and then the first driving The drive value in the motor 400 is stored in association with the displacement value of the lens 100, for example, it can be stored in the form of the following reference table:

镜头100的位移值The displacement value of the lens 100	第一驱动电机400的驱动值The driving value of the first driving motor 400
位移值1displacement value 1	驱动值1drive value 1
位移值2displacement value 2	驱动值2drive value 2
位移值3displacement value 3	驱动值3drive value 3
位移值4displacement value 4	驱动值4drive value 4

Wherein, taking the displacement value of a lens 100 as an example, when its driving value is "displacement value 1", the driving value of the first driving motor 400 is "driving value 1".

After the first execution module 620 obtains the first shake compensation data, it can obtain the drive value corresponding to the first shake compensation data by querying the form of the above table, and then use the drive value to control the first drive motor 400 to The lens 100 is driven to move. However, since the driving value of the first driving motor 400 and the displacement value of the lens 100 are pre-tested, in practical applications, when the corresponding driving value is used to control the first driving motor 400, the displacement value of the actual movement of the lens 100 is not necessarily The displacement value corresponding to the driving value can be achieved, so that the anti-shake error of the lens 100 is relatively large.

Based on this, the embodiment of the present application provides another way to solve the above problem. Please refer to FIG. 6 . FIG. 6 is a schematic diagram of a fourth structure of a dual anti-shake system provided by an embodiment of the present application. The first driving chip 600 can also include a first detection module 660, the first detection module 660 is connected with the lens 100, the first detection module 660 can detect the current displacement data of the lens 100, and compare the current displacement data of the lens 100 with the first shaking The compensation data is compared to obtain the first comparison result, and the first comparison result is fed back to the first execution module 620. After receiving the first comparison result, the first execution module 620 can judge whether the first comparison result satisfies the first requirement. If the requirement is set, if the first comparison result does not meet the first preset requirement, a third driving value is obtained according to the first comparison result, and the first driving motor 400 is controlled to drive the lens 100 to move according to the third driving value. The first preset requirement may be a preset requirement, for example, the first preset requirement may be set such that the actual displacement of the lens 100 is less than a first threshold.

Exemplarily, assuming that the current position information of the lens 100 is (2, 3), and the first shake compensation data calculated by the first driving chip 600 is (-1, -2), then according to the current position information and the first The shake compensation data can determine that the target position information is (1, 1), but due to the error between the drive value of the first driving motor 400 and the displacement value of the lens 100, the lens 100 cannot move to the target position information, assuming that at this time Assuming that the lens 100 moves only 0.5 unit length in the X-axis direction and 1 unit length in the Y-axis direction, the current displacement data of the lens 100 is (-0.5, -1). The first detection module 660 can detect the current displacement data of the lens 100, and compare (-0.5, -1) with (-1, -2) to obtain the X-axis displacement of the lens 100 from the target position information The difference is 0.5 unit length, and the displacement of the Y axis is still 1 unit length. The comparison result is fed back to the first execution module 620. After obtaining the comparison result, the first execution module 620 knows that the lens 100 If the actual displacement is not less than the threshold value, the third drive value is obtained according to the comparison result, and the first drive motor 400 is controlled with the third drive value to drive the lens 100 to move, and the above process is repeated until the first comparison result satisfies The first preset requirement so far.

It can be understood that the embodiment of the present application can continuously detect and adjust the current displacement data of the lens 100, so that the actual displacement of the lens 100 meets the first preset requirement. For example, the anti-shake accuracy of the lens 100 can be improved.

The control of the second drive motor 500 by the second execution module 720 may be the same as that of the first execution module 620. For example, when the first execution module 620 controls the first drive motor 400 using the first preset mapping relationship, the second execution The module 720 may also use the second preset mapping relationship to control the second driving motor 500 .

Specifically, the driving value of the second driving motor 500 and the displacement value of the photosensitive element 200 can be tested in advance to determine the corresponding relationship between the second driving motor 500, and then the second driving motor 500 can be associated and stored, for example, It is stored in the form of the following reference table:

感光元件200的位移值Displacement value of photosensitive element 200	第一驱动电机400的驱动值The driving value of the first driving motor 400
位移值adisplacement value a	驱动值adriving value a
位移值bdisplacement value b	驱动值bdriving value b
位移值cdisplacement value c	驱动值cdriving value c
位移值ddisplacement value d	驱动值ddrive value d

Wherein, taking the displacement value of a photosensitive element 200 as an example, when its driving value is “displacement value b”, the driving value of the second driving motor 500 is “driving value b”.

After the second execution module 720 obtains the second jitter compensation data, it can obtain the driving value corresponding to the second jitter compensation data by querying the form of the above table, and then use the driving value to control the second driving motor 400 to Drive the photosensitive element 200 to move.

Certainly, when the first execution module 620 controls the first driving motor 400 in the manner of the first preset mapping relationship, the second execution module 720 may also control the second driving motor 500 in another manner. Please continue to refer to FIG. 6, the second driver chip 700 can also include a second detection module 740, the second detection module 740 is connected to the photosensitive element 200, the second detection module 740 can detect the current displacement data of the photosensitive element 200, and the photosensitive element The current displacement data of 200 is compared with the second shake compensation data to obtain a second comparison result, and the second comparison result is fed back to the second execution module 720. After receiving the second comparison result, the second execution module 720 can judge Whether the second comparison result meets the second preset requirement, if the second comparison result does not meet the second preset requirement, then obtain the fourth drive value according to the second comparison result, and control the second drive motor 500 according to the fourth drive value Drive the photosensitive element 200 to move. The second preset requirement may be a preset requirement, for example, the second preset requirement may be set such that the actual displacement of the photosensitive element 200 is less than a second threshold. Wherein, for the specific control process, reference may be made to the related description of the above-mentioned first detection module 660, which will not be repeated here.

It should be noted that when the first driving chip 600 uses the above-mentioned first detection module 660 to continuously adjust the control process of the first driving motor 400, the second driving chip 600 can also use the above-mentioned second detection module 740 to perform the first Second, the control process of the driving motor 500 is continuously adjusted.

It should be noted that the connection of the various components described in the embodiments of the present application is not limited to using conductors for wired connections, and wireless communication connections may also be made through Bluetooth, Wi-Fi signals or other wireless connection methods.

Among them, since the movement of the lens 100 and the movement of the photosensitive element 200 need to be coordinated, the movement of the lens 100 and the photosensitive element 200 can be reasonably arranged according to the shaking data to achieve optical image stabilization, so as to achieve a larger angle of optical image stabilization and effectively improve the camera image quality. The optical anti-shake effect of the group 20 will be specifically described below for the control logic of the first driver chip 600 and the second driver chip 700 .

If the shake data of the camera module 20 does not exceed the first shake threshold, acquire the first shake compensation data and the second shake compensation data; the first execution module 620 drives the lens 100 along the optical axis direction of the lens 100 in response to the first shake compensation data moving and/or moving in a direction perpendicular to the optical axis of the lens 10 ; the second execution module 720 drives the photosensitive element 200 to rotate in a direction perpendicular to the optical axis of the lens 100 in response to the second shake compensation data.

Taking an example where the lens 100 can achieve a maximum of 2 degrees of translational stabilization, and the photosensitive element 200 can achieve a maximum of 2 degrees of translational stabilization and 3 degrees of rotational stabilization, the first shake threshold can be set to 2 degrees. Exemplarily, when the shaking angle of the camera module 20 is 1.5 degrees, the current position of the lens 100 is (Xc, Yc), and the current position of the photosensitive element 200 is (X1, Y1), the shaking data of the camera module 20 is translation Offset and rotation offset are generated. For example, 1 degree in 1.5 degrees is caused by the translational offset of the camera module 20, and 0.5 degrees is caused by the rotation offset of the camera module 20. According to the shake data of the camera module 20, it is calculated as 1.5 degrees. The first shake compensation data: the first translation amount of the lens (-Xd, -Yd), and the calculated second shake data: the first rotation amount of the photosensitive element 200 (-X2, -Y2), (X3, 0). The first driving module 620 drives the lens to translate Xd unit lengths along the negative direction of the X axis and Yd unit lengths along the negative direction of the Y axis according to the first translation amount, so that the lens 100 is at the target position (Xc-Xd, Yc -Xd). The second driving module 720 drives the first part of the photosensitive element 200 to move X2 unit lengths along the negative direction of the X-axis according to the first rotation amount, drives the second part of the photosensitive element 200 to move X3 unit lengths along the positive direction of the X-axis, and drives The third part of the photosensitive element moves Y2 unit length along the negative direction of the Y axis, so that the photosensitive element 200 is at the target position (X4, Y4), wherein, the target position (X4, Y4) of the photosensitive element 200 is the direction passing through the photosensitive element 200 The positions of different parts are translated to the rotated position.

It should be noted that since the movement of the photosensitive element 200 may include translation and rotation, the translation and rotation need to be driven by a driving assembly, and the rotation is realized by driving the translation of different parts of the photosensitive element 200, for example, by driving different parts of the photosensitive element 200 along the same The translation in the opposite direction of the coordinate axis, or the translation of different parts of the photosensitive element 200 on the same coordinate axis driven by different driving speeds, can make the photosensitive element 200 rotate along the preset axis. Since the translation and rotation share a stroke, the translation amount reaches the maximum stroke , it will not be able to rotate; when the rotation reaches the maximum stroke, it will not be able to translate. Based on this, the present application needs to reasonably arrange the movement of the lens 100 and the photosensitive element 200 according to the shake data, so as to achieve greater angle anti-shake.

If the shake data of the camera module 20 exceeds the first shake threshold and does not exceed the second shake threshold, acquire the first shake compensation data and the second shake compensation data; the first execution module 620 drives the lens 100 in response to the first shake compensation data move along the optical axis of the lens 100 and/or move along a direction perpendicular to the optical axis of the lens 100; the second execution module 720 drives the photosensitive element 200 to move along a direction perpendicular to the optical axis of the lens 100 and/or in response to the second shake compensation data Rotate perpendicular to the direction of the optical axis of the lens 100 . .

Wherein, the second threshold may be 3 degrees. Since the lens 100 can achieve a translation compensation of up to 2 degrees, assuming that the camera module 20 shake data is determined to be 2.5 degrees based on the shake data, the camera module 200 needs to be translated by the lens 100 and the photosensitive element 200 to stabilize the camera module 200. The position of the sensor is (Xe, Ye), the current position of the photosensitive element 200 is (X5, Y5), and the first shake compensation data and the second shake compensation data are calculated according to the shake data of 2.5 degrees: the third translation amount of the lens 100 (- Xf, -Yf), the fourth translation amount of the photosensitive element 200 (-X6, -Y6), the first execution module 620 responds to the first shake compensation data, and drives the lens 100 along the negative direction of the X axis according to the obtained third translation amount Translate by Xf unit lengths, and translate by Yf unit lengths along the negative direction of the Y axis, so that the lens 100 is at the target position (Xe-Xf, Ye-Xf). The second execution module 720 responds to the second jitter data, and drives the photosensitive element 200 to move X6 unit lengths along the negative direction of the X axis and Y6 unit lengths along the negative direction of the Y axis according to the obtained fourth translation amount, So that the photosensitive element 200 is at the target position (X5-X6, Y5-Y6).

In some embodiments, assuming that the jitter data of the camera module 20 is determined to be 3 degrees according to the jitter data, 0.5 degrees of which are caused by the rotation offset of the camera module 20, the translation of the lens 100, the translation of the photosensitive element 200 and the photosensitive The element 200 is rotated to stabilize the camera module 20. At this time, the current position of the lens 100 can be obtained as (Xg, Yg), and the current position of the photosensitive element 200 is (X7, Y7), which is calculated according to the shaking data of 3 degrees The first shaking data: the fifth translation amount of the lens (-Xh, -Yh), and the second shaking compensation data: the sixth translation amount of the photosensitive element (-X8, -Y8), the second rotation amount of the photosensitive element (X9, Y9) , (X10, 0). The first execution module 620 drives the lens 100 to translate Xh unit lengths along the negative direction of the X axis and Yh unit lengths along the negative direction of the Y axis according to the fifth translation amount, so that the lens 100 is at the target position (Xg-Xh, Yg-Yh). The second execution module 720 drives the photosensitive element 200 to move X8 unit lengths along the negative direction of the X axis and Y8 unit lengths along the negative direction of the Y axis according to the sixth translation amount, so that the photosensitive element 200 is in the position (X7-X8, Y7-Y8).

In the embodiment of the present application, 2.5 degrees of anti-shake of the camera module 20 can be achieved through the translation of the lens 100 and the photosensitive element 200 , and the remaining 0.5 degrees of anti-shake can be compensated by the rotation of the photosensitive element 200 . Wherein, the second execution module 720 can drive the first part of the photosensitive element 200 to translate X9 unit lengths along the positive direction of the X-axis according to the second rotation amount, and drive the second part of the photosensitive element 200 to translate X10 along the positive direction of the X-axis. unit length, drive the third part of the photosensitive element 200 to translate Y9 units along the positive direction of the Y axis, and compensate the remaining 0.5 degree jitter data, so that the target position of the photosensitive element is at (X11, Y11).

It can be understood that when the jitter data is greater than 2 degrees and less than or equal to 3 degrees, the lens 100 will perform translation compensation in its entirety, and the photosensitive element 200 will perform translation compensation first. Make compensation. By rationally arranging the motion compensation of the lens 100 and the photosensitive element 200 , the 3-degree combined optical dual anti-shake of the camera module 20 can be realized.

If the shake data of the camera module 20 exceeds the second shake threshold, acquire the first shake compensation data and the second shake compensation data; the first execution module 620 drives the lens 100 to move along the optical axis of the lens 100 in response to the first shake compensation data and/or move in a direction perpendicular to the optical axis of the lens 100 ; the second execution module 720 drives the photosensitive element 200 to move in a direction perpendicular to the optical axis of the lens 100 in response to the second shake compensation data.

Exemplarily, assuming that the shaking data of the camera module 20 is 3.1 degrees, the current position of the lens 100 is (Xi, Yi), and the current position of the photosensitive element 200 is (X12, Y12), according to the shaking data of the camera module 20, the lens The current position of 100 and the current position of the photosensitive element 200 determine the first shake compensation data: the seventh translation amount of the lens (-Xj, -Yj), and the second shake compensation data: the eighth translation amount of the photosensitive element (-X13, -Y13 ). The first execution module 620 may drive the lens 100 to translate Xj unit lengths along the negative direction of the X axis and Yj unit lengths along the negative direction of the Y axis according to the obtained seventh translation amount, so that the lens 100 is at the target position (Xi -Xj, Yi-Xj). The second execution module 720 can drive the photosensitive element 200 to move X13 unit lengths along the negative direction of the X axis and X13 unit lengths along the negative direction of the Y axis according to the eighth translation amount, so that the photosensitive element 200 is at the target position (X12 -X13, Y12-Y13).

It can be understood that when the shaking data is greater than 3 degrees, the lens 100 will perform translation compensation and the photosensitive element 200 will perform translation compensation. By reasonably arranging the motion compensation of the lens 100 and photosensitive element 200, the camera module 20 can be realized to be greater than 3 degrees. optical image stabilization.

It should be noted that the range of the shaking data above is only exemplary, and can be specifically set according to the maximum anti-shake angle of the lens 100 and the maximum anti-shake angle of the photosensitive element 200 , which is not limited in this embodiment of the present application.

It should also be noted that the relationship between the first driving chip 600 and the second driving chip 700 , the lens 100 and the photosensitive element 200 in the embodiment of the present application is not limited thereto. Exemplarily, the first driving chip 600 can also control the movement of the photosensitive element 200 , and the second driving chip 700 can also control the movement of the lens 100 .

Exemplarily, if the shake data of the camera module 20 does not exceed the first shake threshold, the first shake compensation data and the second shake compensation data are acquired, and the first execution module 620 may drive the photosensitive element 200 in response to the first shake compensation data. Rotate in a direction perpendicular to the optical axis of the lens 100; the second execution module 720 may drive the lens 100 to move in a direction perpendicular to the optical axis of the lens 100 and/or in a direction perpendicular to the optical axis of the lens 100 in response to the second shake compensation data. If the shake data of the camera module 20 exceeds the first shake threshold and does not exceed the second shake threshold, acquire the first shake compensation data and the second shake compensation data; the first execution module 620 drives the photosensitive element in response to the first shake compensation data 200 moves in a direction perpendicular to the optical axis of the lens 100 and/or rotates in a direction perpendicular to the optical axis of the lens 100; the second execution module 720 drives the lens 100 to move in the direction of the optical axis of the lens 100 and/or in response to the second shake compensation data Move in a direction perpendicular to the optical axis of the lens 100. If the jitter data of the camera module 20 exceeds the second jitter threshold, the first jitter compensation data and the second jitter compensation data are acquired; the first execution module 620 drives the photosensitive element 200 along the light direction perpendicular to the lens 100 in response to the first jitter compensation data. axial movement; the second execution module 720 drives the lens 100 to move along the optical axis of the lens 100 and/or to move along a direction perpendicular to the optical axis of the lens 100 in response to the second shake compensation data.

Shake amount in the direction of the optical axis of the lens 100. The second driving module 430 is arranged on the carrier 410, and the second driving module 430 can drive the carrier 410 to move along the direction perpendicular to the optical axis of the lens 100 so as to drive the lens 100 to move along the direction perpendicular to the optical axis of the lens 100, so as to compensate the 100 The shake amount in the direction perpendicular to the optical axis of the lens 100 . Compared with the related art which uses only one shrapnel-type drive motor or one ball-type drive motor to realize the displacement in the horizontal direction and the vertical direction at the same time, the embodiment of the present application uses two different drive modules to perform two different displacements on the carrier 410 respectively. Direction driving can prevent damage to some components of the driving module when the same driving module simultaneously realizes displacement in two different directions, thereby improving the anti-shake reliability of the first driving motor 400 and improving the first driving The overall performance of the motor 400.

In addition, the inventors have found through long-term research that the shrapnel-type drive motors of some mobile phones usually use the shrapnel structure and the ring structure to realize the horizontal and vertical displacement of the drive motor to drive the horizontal and vertical displacement of the lens. In the process of realizing the horizontal displacement, the problem of the shrapnel structure and/or the breakage of the ring wire is easy to occur; the ball-type driving motor of some mobile phones usually uses multiple balls to realize the horizontal and vertical displacement of the driving motor to drive the horizontal direction of the lens And the displacement in the vertical direction, however, in the process of realizing the displacement in the vertical direction, multiple balls will collide with each other, so that the multiple balls are prone to pits, resulting in the problem of unsmooth rolling.
