[0064] The example embodiments will be described in detail herein with reference to the accompanying drawings. In the following description, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following example embodiments are not meant to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0065] As described in the background, in the related art, in the anti-shake control of the terminal, the data of the gyroscope on the terminal needs to be called, and the time for data acquisition is relatively long, so the delay of the anti-shake control according to the acquired data is relatively large, which further causes the error of the anti-shake compensation to increase, and the anti-shake effect is limited.

[0066] Therefore, the present disclosure provides an anti-shake control method, device, electronic device and medium to reduce the error of the anti-shake compensation.

[0067] Figure 1 is a flowchart of an anti-shake control method according to an example embodiment. Referring to Figure 1 The embodiments of the present disclosure provide an anti-shake control method, which can include steps S21 and S22.

[0068] In step S21, a shaking parameter of a gyroscope arranged on a camera module is acquired, wherein the camera module can include an anti-shake lens and a lens barrel.

[0069] Figure 2 is a structural schematic diagram of a gyroscope according to an example embodiment. Referring to Figure 2, the gyroscope 10 can include a rotating ring 11, an inner balance ring 12, an outer balance ring 13, and a base 14, the base 14 can be fixed in a lens barrel (not shown in the figure), the outer balance ring 13 can be rotationally arranged in the base 14 (for example, the outer balance ring 13 can be connected with the base 14 through a rotating shaft), the inner balance ring 12 can be rotationally arranged in the outer balance ring 13 (for example, the inner balance ring 12 can be connected with the outer balance ring 13 through a rotating shaft), the rotating ring 11 can be rotationally arranged in the inner balance ring 12 (for example, the rotating ring 11 can be connected with the inner balance ring 12 through a rotating shaft), and an anti-shake lens (not shown in the figure) can be fixed in the rotating ring 11. For example, the anti-shake lens can be adhesively fixed on the rotating ring 11, or the anti-shake lens can also be clamped in the rotating ring 11.

[0070] Referring to Figure 2 , the rotation axis of the outer balance ring 13 can be perpendicular to the rotation axis of the inner balance ring 12, and the rotating shaft axis of the rotating ring 11 can be perpendicular to the rotating shaft axis of the inner balance ring 12. In this way, when the lens module shakes, the outer balance ring 13 can rotate relative to the base 14, the inner balance ring 12 can rotate relative to the outer balance ring 13, and the rotating ring 11 can rotate relative to the inner balance ring 12.

[0071] In this way, the shaking parameter of the camera module can be obtained through the gyroscope on the camera module, which can improve the speed of obtaining the shaking parameter, facilitate to reduce the delay of the shaking compensation, and further facilitate to reduce the error of the shaking compensation.

[0072] In step S22, the gyroscope is controlled to operate according to the obtained shaking parameter, so as to drive the anti-shake lens to perform shaking compensation.

[0073] In the scheme, the original driving structure of the anti-shake lens can be omitted by controlling the gyroscope to operate to drive the anti-shake lens to perform shaking compensation, which facilitates to simplify the structure of the lens module.

[0074] Based on Figure 2 The shaking parameter of the gyroscope can include the shaking angles of the outer balance ring, the inner balance ring, and the rotating ring.

[0075] In this way, by obtaining the shaking angles of the outer balance ring, the inner balance ring, and the rotating ring, the deflection of the anti-shake lens fixed on the rotating ring can be determined, so as to facilitate to perform shaking compensation.

[0076] Figure 3 is a flow chart of an anti-shake control method according to another exemplary embodiment. Referring to Figure 2 and Figure 3 Step S22 can include step S221 and step S222.

[0077] In step S221, the target compensation rotation angle of the outer gimbal ring, the inner gimbal ring and the rotation ring is determined respectively according to the jitter angle of the outer gimbal ring, the inner gimbal ring and the rotation ring.

[0078] It can be understood that the jitter angle of the outer gimbal ring, the inner gimbal ring and the rotation ring can represent the deflection degree of the anti-shake lens, and thus the target compensation rotation angle of the outer gimbal ring, the inner gimbal ring and the rotation ring can be determined respectively according to the jitter angle of the outer gimbal ring, the inner gimbal ring and the rotation ring.

[0079] In step S222, the outer gimbal ring, the inner gimbal ring and the rotation ring are controlled to rotate the corresponding target compensation rotation angle, so that the anti-shake lens is driven to perform jitter compensation.

[0080] In this scheme, the jitter compensation of the anti-shake lens is realized by controlling the rotation of the outer gimbal ring, the inner gimbal ring and the rotation ring of the gyroscope, and the anti-shake lens can realize jitter compensation by using the corresponding rotation shaft of the outer gimbal ring, the inner gimbal ring and the rotation ring. The rotation of the anti-shake lens is more flexible, which is convenient for better jitter compensation.

[0081] For example, the jitter angle of the outer gimbal ring, the inner gimbal ring and the rotation ring can be determined according to the detection time length and the instantaneous angular velocity of the outer gimbal ring, the inner gimbal ring and the rotation ring.

[0082] For example, the jitter angle of the outer gimbal ring, the inner gimbal ring and the rotation ring can be obtained by integrating once according to the detection time length and the instantaneous angular velocity of the outer gimbal ring, the inner gimbal ring and the rotation ring.

[0083] For example, the jitter angle of the outer gimbal ring, the inner gimbal ring and the rotation ring can be calculated by the following formula:

[0084]

[0085] In formula (1), A is the jitter angle of the outer gimbal ring, x is the instantaneous angular velocity of the outer gimbal ring, t1 is the start time of jitter detection, and t2 is the end time of jitter detection. It can be understood that the difference between t2 and t1 can be the detection time length.

[0086]

[0087] In formula (2), B is the jitter angle of the inner gimbal ring, and y is the instantaneous angular velocity of the inner gimbal ring.

[0088]

[0089] In formula (3), C is the jitter angle of the rotation ring, and z is the instantaneous angular velocity of the rotation ring.

[0090] For example, the deflection angle can include a first deflection component of the anti-shake lens deflected along the rotation axis of the outer balance ring, a second deflection component of the anti-shake lens deflected along the rotation axis of the inner balance ring, and a third deflection component of the anti-shake lens deflected along the rotation axis of the rotating ring. The step of determining the deflection angle of the anti-shake lens according to the shake angle of each of the outer balance ring, the inner balance ring and the rotating ring can include:

[0091] The first deflection component is determined according to the shake angle of the outer balance ring, the second deflection component is determined according to the shake angle of the inner balance ring, and the third deflection component is determined according to the shake angle of the rotating ring.

[0092] For example, the first deflection component can be equal in value to the shake angle of the outer balance ring, the second deflection component can be equal in value to the shake angle of the inner balance ring, and the third deflection component can be equal in value to the shake angle of the rotating ring.

[0093] In this way, after obtaining the shake angle of each of the outer balance ring, the inner balance ring and the rotating ring, the first deflection component, the second deflection component and the third deflection component of the anti-shake lens can be determined.

[0094] On the basis of determining the first deflection component, the second deflection component and the third deflection component of the anti-shake lens, the step of determining the target compensation rotation angle of the outer balance ring, the inner balance ring and the rotating ring according to the deflection angle can include:

[0095] The target compensation rotation angle of the outer balance ring is determined according to the first deflection component, the target compensation rotation angle of the inner balance ring is determined according to the second deflection component, and the target compensation rotation angle of the rotating ring is determined according to the third deflection component.

[0096] For example, the target compensation rotation angle of the outer balance ring can be equal in value to the first deflection component, the target compensation rotation angle of the inner balance ring can be equal in value to the second deflection component, and the target compensation rotation angle of the rotating ring can be equal in value to the third deflection component.

[0097] In this way, after determining the target compensation rotation angle of the outer balance ring, the inner balance ring and the rotating ring, the outer balance ring, the inner balance ring and the rotating ring can be controlled to rotate the corresponding target compensation rotation angle to drive the anti-shake lens to perform shake compensation.

[0098] Figure 4 is a structural schematic diagram of a gyroscope according to another example embodiment, Figure 5 is a structural schematic diagram of a gyroscope according to another example embodiment, Figure 6 is a structural schematic diagram of a gyroscope according to another example embodiment, Figure 7is a structural schematic diagram of a gyroscope according to yet another exemplary embodiment. Referring to Figure 2 , Figure 4 to Figure 7 For example, the rotation axis of the outer gimbal ring 13 can coincide with the central axis of the camera module. For example, the initial state of the gyroscope can be the state shown in Figure 4 and Figure 5 , Figure 5 may be a view in the direction of arrow E in Figure 4 . Referring to Figure 4 and Figure 5 , the initial state of the gyroscope can be that the outer gimbal ring 13 is parallel to the horizontal plane, the inner gimbal ring 12 and the rotating ring 111 are kept in a vertical state, and the plane in which the inner gimbal ring 12 and the rotating ring 11 are located is perpendicular to the rotation axis of the outer gimbal ring 13, Figure 4 may be parallel to the rotation axis of the inner gimbal ring 12, for example.

[0099] In the case of camera module shaking, the outer gimbal ring 13, the inner gimbal ring 12 and the rotating ring 11 can rotate, for example, in one possible case, at the end of the shaking detection, the state of the gyroscope can be the state shown in Figure 6 and Figure 7 , wherein Figure 6 may have the same view angle as Figure 4 , Figure 7 may be a view of the gyroscope in the direction of arrow F in Figure 6 , Figure 7 may have the same view angle as the view angle of Figure 5 .

[0100] At the end of the shaking detection, the shaking angles of the outer gimbal ring 13, the inner gimbal ring 12 and the rotating ring 11 can be determined, for example, with reference to the above formulas (1) to (3), so that the first deflection component can be determined according to the shaking angle of the outer gimbal ring 13, the second deflection component can be determined according to the shaking angle of the inner gimbal ring 12, and the third deflection component can be determined according to the shaking angle of the rotating ring 11.

[0101] Subsequently, the target compensation rotation angle of the outer gimbal ring 13 can be determined according to the first deflection component, the target compensation rotation angle of the inner gimbal ring 12 can be determined according to the second deflection component, and the target compensation rotation angle of the rotating ring 11 can be determined according to the third deflection component. Finally, the outer gimbal ring 13, the inner gimbal ring 12 and the rotating ring 11 are respectively controlled to rotate the corresponding target compensation rotation angles, so that the anti-shake lens is driven to perform shaking compensation.

[0102] For example, in one possible case, after the anti-shake lens is driven to perform shaking compensation, the gyroscope can return to the state shown in Figure 4 and Figure 5 .

[0103] In a possible implementation, the lens module can include a processor, and the method can be applied to the processor on the lens module. In this way, the lens module can realize the anti-shake compensation by itself, facilitating the modular design of the terminal.

[0104] Figure 8 is a block diagram of an anti-shake control device according to an example embodiment. Referring to Figure 8 , the embodiments of the present disclosure also provide an anti-shake control device 400, which can include an acquisition module 401 and a compensation module 402.

[0105] The acquisition module 401 can be configured to acquire a shaking parameter of a gyroscope arranged on a camera module, where the camera module can include an anti-shake lens and a lens barrel, the gyroscope includes a rotating ring, an inner balance ring, an outer balance ring, and a base, the base is fixed in the lens barrel, the outer balance ring is rotationally arranged in the base, the inner balance ring is rotationally arranged in the outer balance ring, the rotating ring is rotationally arranged in the inner balance ring, and the anti-shake lens is fixed on the rotating ring.

[0106] The compensation module 402 can be configured to control the gyroscope to operate according to the shaking parameter, so as to drive the anti-shake lens to perform shaking compensation.

[0107] In this way, the shaking parameter of the camera module can be quickly acquired by the gyroscope arranged on the lens module, so that the shaking compensation can be more quickly realized. In this way, the reaction time of the shaking compensation can be shortened, and the error of the shaking compensation can be reduced.

[0108] Further, in the present solution, the anti-shake lens is arranged on the gyroscope, and after the anti-shake parameter is acquired by the gyroscope, the gyroscope can be controlled to operate according to the shaking parameter, so as to drive the anti-shake lens to perform shaking compensation. In this way, the structure of the lens module can be simplified.

[0109] For example, the shaking parameter can include a shaking angle of each of the outer balance ring, the inner balance ring, and the rotating ring.

[0110] For example, the compensation module 402 can include:

[0111] A first compensation submodule can be configured to determine a target compensation rotation angle of each of the outer balance ring, the inner balance ring, and the rotating ring according to the shaking angle of each of the outer balance ring, the inner balance ring, and the rotating ring.

[0112] A second compensation submodule can be configured to control each of the outer balance ring, the inner balance ring, and the rotating ring to rotate the corresponding target compensation rotation angle.

[0113] Exemplarily, the first compensation submodule can be configured to determine the target compensation rotation angle of the outer balance ring, the inner balance ring and the rotating ring respectively according to the jitter angle of the outer balance ring, the inner balance ring and the rotating ring respectively, by the following manner:
