In some embodiments, the maximum shooting perspective within the shooting perspective range of the first camera module is equal to: the sum of the maximum viewing angle of the first lens assembly and twice the maximum rotation angle of the light deflection assembly.

On the basis of the maximum visual angle of the first lens assembly of the first camera module, the maximum rotation angle of the light deflection assembly is increased by two times, so that the shooting visual angle range of the first camera module is enlarged, and the adjustability of the visual angle range is increased. Therefore, when the target view finding object is detected to enter the shooting visual angle range of the first camera module, the target view finding object can be tracked by adjusting the deflection angle of the light deflection assembly.
Here, the implementation of tracking of the target finder object means: when the position of the target viewing object in the viewing picture is changed, the target viewing object is placed at the central position of the first viewing picture by rotating the light deflection component of the first camera module, so that the target viewing object can appear on each viewing picture.

The maximum viewing angle of the first lens assembly refers to a diagonal viewing angle of the first lens assembly, and the maximum viewing angle of the second lens assembly refers to a diagonal viewing angle of the second lens assembly. Like this, through the turned angle setting with light deflection subassembly in setting for the within range, can be on realizing that light deflection subassembly pivoted basis, save the inside space of camera subassembly.
In some embodiments, the four times the set angle threshold is greater than or equal to a difference between a maximum viewing angle of the second lens assembly and a maximum viewing angle of the first lens assembly.
In some embodiments, since the quadruple set angular threshold (D) is greater than or equal to the difference between the maximum viewing angle (B) of the second lens assembly and the maximum viewing angle (C) of the first lens assembly, i.e. 4D > B-C, then D >1/4(B-C), since the maximum rotation angle (a) of the light deflecting assembly is greater than or equal to the set angular threshold (D), i.e. a > D >1/4(B-C), it can be seen that 2A > (B-C) 50%, that is to say that twice said maximum rotation angle (a) of the light deflecting assembly is greater than or equal to more than 50% of the angular difference between the diagonal view (B) of the second lens assembly and the maximum viewing angle (C) of the first lens assembly.
For example, when the maximum angle of view of the first lens assembly is 40 degrees and the maximum angle of view of the second lens assembly of the second camera module is 80 degrees, the angle threshold is set to be greater than or equal to: the difference between the maximum viewing angle of the second lens assembly and the maximum viewing angle of the first lens assembly is divided by 4, i.e., 10 degrees, that is, the rotation angle of the light deflecting assembly is greater than or equal to 10. For example, the light deflecting component is a prism that the Pitch axis can rotate +/-5 degrees.

The distance between any two adjacent lenses can be changed, and the focal length of the first lens assembly can be adjusted by changing the distance between any two adjacent lenses in the plurality of lenses.
Here, the second driving assembly may be connected with the first lens assembly. In some embodiments, the second drive assembly may include a rail parallel to the optical axis of the lens, the rail being slidably coupled to the plurality of lenses.

Since the camera module in the embodiment of the present disclosure has the first camera module and the second camera module, it is possible to form two viewing frames with different angles, that is, a first viewing frame of the first camera module and a second viewing frame of the second camera module, and the electronic device can synthesize the first viewing frame and the second viewing frame to generate the target image. Since the position of the target subject has been changed based on the rotation of the light deflecting element, the target subject can be displayed in the generated target image even if the position of the target subject is changed during the framing.
In some embodiments, when it is detected that the target viewing object in the shooting visual angle range of the second camera module moves into the shooting visual angle range of the first camera module, the electronic device may control the second driving assembly to drive the plurality of lenses included in the first lens assembly to move so as to achieve optical zooming of the first camera module, and control the first driving assembly to drive the light deflecting assembly to rotate while performing the optical zooming so as to place the target viewing object in the center position of the first viewing picture of the first camera module.
In some embodiments, the target view object in the view frame may be identified based on a preset object identifier, for example, the preset object identifier may be represented by a preset graph, and the preset graph may be displayed as a frame. For example, the position of the target viewing object is represented by the position of the recognition frame in the viewing screen, that is, the center position of the recognition frame can be used as the center position of the target viewing object.
In some embodiments, in response to the first input, in a case where it is detected that a pixel variation amount of the center position of the preset object flag is greater than or equal to a difference value between a short-edge pixel of the first finder picture and a short-edge pixel of the preset object flag, it is determined that the target finder object within the photographing view angle range of the second camera module is detected to move into the photographing view angle range of the first camera module. Here, whether the target viewing object moves within the range of the photographing angle of view of the first camera module may be determined based on the amount of pixel change of the preset object identification, thereby enabling tracking of the position of the target viewing object.
In some embodiments, in a case where it is detected that the pixel variation amount of the center position of the preset object identifier is smaller than the difference between the short-side pixel of the first viewing picture and the short-side pixel of the preset object identifier, it is determined that the target viewing object is located in the first viewing picture and does not move to a position outside the first viewing picture, and at this time, the tracking of the target viewing object corresponding to the preset object identifier may be stopped.
In some embodiments, when the pixel variation amount of the center position of the preset object identifier is greater than or equal to the difference value between the short-edge pixel of the viewing picture and the short-edge pixel of the preset object identifier, the tracking of the target viewing object corresponding to the preset object identifier is continued. Here, the moving track of the target viewing object can be determined based on the pixel variation of the preset object identifier, and then whether the target viewing object is in the first viewing picture of the first camera module is determined, when the target viewing object exceeds or is about to exceed the range of the first viewing picture, the angle of the light deflection component can be adjusted in time, and the tracking of the target viewing object is realized.
In the embodiment of the disclosure, the first camera module is provided with the light deflection assembly capable of rotating around at least two rotating shafts, and in the process of framing the picture by the first lens assembly, if it is detected that a target framing object in the shooting visual angle range of the second camera module moves into the shooting visual angle range of the first camera module, the first driving assembly can be controlled to drive the light deflection assembly to rotate, and the target framing object is placed at the center position of a first framing picture of the first camera module.
In the embodiment of the disclosure, in the process of moving the target viewing object, the switching of the position of the target viewing object can be realized through the optical deflection component of the camera module, and compared with the arrangement of a plurality of different camera modules, the optical zoom is realized, so that the position of the target viewing object can be tracked in real time, the structure of the camera module can be simplified, and the use experience of a user is improved.
In some embodiments, the method further comprises:
determining a current position of the target viewing object in a second viewing frame of a second camera module;
the control first drive assembly drives the light deflection assembly to rotate, and comprises:
determining a vector value between the current position and a center position of the second viewfinder frame;
and controlling the first driving assembly to drive the light beam deflection assembly to rotate based on the vector value.
In some embodiments, the controlling the first driving assembly to drive the light deflecting assembly to rotate includes: and determining a relative position between the current position and the central position of the second framing picture, and controlling the first driving assembly to drive the light beam deflection assembly to rotate based on the relative position. Wherein the relative position may be represented based on a vector value or a coordinate value between the current position and the center position of the second finder screen.
Taking the example that the relative position is expressed based on the vector value, after determining the current position of the target viewing object in the second viewing frame of the second camera module, the vector value between the current position and the center position of the second viewing frame can be determined, and since the vector value carries the direction information and the distance information of the current position and the center position of the second viewing frame, the first driving assembly can be controlled to drive the light deflecting assembly to rotate in the corresponding direction, for example, in the opposite direction or the same direction of the current position and the center position of the second viewing frame based on the vector value.
Fig. 6 is an operation diagram of a camera module according to an exemplary embodiment, as shown in fig. 6, before driving the light deflection assembly of the first camera module to rotate, a frame (wide-angle image) includes a first object 601 and a second object 602 (telephoto image), wherein the first object is located at a first position of the frame, the second object is located at a second position of the frame, and the second object 602 is a target frame. When it is detected that the second object 602 within the shooting visual angle range of the second camera module 603 moves into the shooting visual angle range of the first camera module 604, the light deflecting assembly 605 can be driven to rotate. After driving the light deflecting element 605 of the first camera module 604 to rotate, the first object 601 is still at the first position, and the second object 602 moves to a third position closer to the first object 601 than the first position. In the embodiment of the present disclosure, in the process of implementing zooming based on the first lens assembly 606, by driving the light deflecting assembly 605 to rotate, the target finder object (the second object 602) can be placed at the center position of the first finder picture of the first camera module 604, so that the target finder object in the finder picture can be tracked and featured while the finder picture is captured.
In some embodiments, the camera module may include a telephoto camera module (first camera module) and a wide-angle camera module (second camera module) that are two-axis (Pitch and Yaw) rotatable by a large angle (≧ 5 degrees), where twice the rotation angle of the prism is greater than or equal to 50% or more of an angular difference between a diagonal view angle of the wide-angle camera module (maximum view angle of the second lens assembly) and a diagonal view angle of the telephoto camera module (maximum view angle of the first lens assembly). For example: the prism with the Pitch capable of axially rotating +/-5 degrees can be arranged, and the camera module with the diagonal visual angle of 80 degrees of the wide-angle camera module and the diagonal visual angle of 40 degrees of the long-focus camera module is matched.
When a target view object to be close-up in a view finding picture of the wide-angle camera module enters a range of a diagonal viewing angle of the telephoto camera module plus 2 times of a prism rotation angle, a synchronous shooting function is started, and the rotation of the prism is controlled by utilizing a vector relation between an identification point of the target view object to be close-up and a midpoint of the view finding picture of the wide-angle camera module, so that the target view finding object to be close-up can be placed at the middle position of the view finding picture of the telephoto camera module (the center position of a first view finding picture of the first camera module) through the viewing angle of the telephoto camera module, wherein the identification point of the target view finding object is used for identifying the current position of the target view finding object and can be the center of an identification frame of the target view finding object.
In some embodiments, when the amount of pixel change of the position of the recognition frame of the target finder object to be close-up is smaller than the pixel difference between the short edge pixel of the finder frame of the telephoto camera module and the short edge pixel of the recognition frame, the prism of the telephoto camera module stops the tracking function, and turns to the anti-shake process of a small angle (0 degree to 3 degrees) for stabilizing the close-up frame. Here, the target finder object may include: a portrait, a landmark building, a vehicle, and/or the like in the finder screen.
The scheme in the embodiment of the disclosure can solve the problem of information loss of the object to be tracked caused by the zoom of the visual angle during the optical zooming, and smooth zooming is performed at any position in the picture, so that the shooting effect is more diversified.
In some embodiments, the method further comprises:
in the process of image shooting, if the camera module is detected to move within a set range, determining the movement parameters of the camera module;
and controlling the first driving assembly to drive the light deflection assembly to rotate corresponding to the movement parameter based on the movement parameter.
In the embodiment of the disclosure, in the process of image shooting, if it is detected that the camera module moves within the set range, the movement parameters of the camera module can be determined, wherein the movement parameters include the movement direction and the displacement of the camera assembly. For example, a gyroscope can be arranged in the camera assembly, then the micro movement of the camera assembly is detected based on the gyroscope, the detected movement information is transmitted to a microprocessor of the camera module to be calculated, the displacement required to be compensated is obtained, then the light deflection assembly is rotated according to the movement direction and the displacement of the camera module, the movement direction and the displacement of the camera module are compensated, and therefore the problem of image blurring caused by the micro movement or shaking of the camera module can be effectively solved.
In some embodiments, the set range may be an angular range of 0 degrees to 3 degrees. That is to say, the light deflection assembly in the embodiment of the present disclosure can perform anti-shake processing of a small angle (0 degree to 3 degrees) on the camera module. In some embodiments, in the process of capturing the view-finding picture, if it is detected that the camera module moves within a set range, determining a movement parameter of the camera module includes: determining whether the camera module works under the minimum magnification in the process of shooting the framing picture; and if the camera module works under the minimum magnification, determining the movement parameters of the camera module.
For example, when the camera module moves, the movement parameters of the camera module can be acquired; obtaining a driving parameter of the first driving component according to the moving parameter; and controlling the first driving assembly to drive the light deflection assembly to rotate based on the driving parameters. For example, if the movement parameter represents that the displacement of the camera module along the first direction is the first displacement, the driving parameter obtained according to the movement parameter is: the first driving assembly is controlled to drive the light deflection assembly to rotate by the first angle along the second direction based on the control module, wherein the second direction can be the direction opposite to the first direction. Here, the movement parameter may be converted into a driving parameter of the first driving assembly based on the microprocessor.
