In the process of zooming, the light deflecting assembly 604 can be controlled to move, after the zoom lens assembly 603 zooms, the light deflecting assembly 604 also rotates from the first angle to the second angle, and the shooting angle of the zoom lens assembly 603 changes from an angle of view 1 to an angle of view 2, where the shooting angle of view is an angle formed by a viewing line and a vertical direction of the camera module in the process of shooting pictures based on the camera module.
In some embodiments, the determining the desired center position of the view picture in the process of picture viewing based on the zoom lens assembly may include: and determining the expected view center position of the view picture in the process of picture view of the zoom lens component based on the minimum magnification.
Here, the desired viewing position of the viewing image may be determined during the image viewing of the zoom lens assembly based on the minimum magnification, and since there are many objects displayed in the viewing image when the camera module operates based on the minimum magnification, the user may determine the desired viewing center from the determination image and adjust the focal length of the zoom lens assembly as needed, which is convenient for identification and operation. In some embodiments, the zoom lens assembly may also determine a desired center position of the view of the frame during frame viewing at a set magnification, wherein the set magnification is greater than or equal to a minimum magnification and less than or equal to a maximum magnification.
In the embodiment of the disclosure, under the condition that the camera module operates based on the minimum magnification, smooth zoom switching can be performed on any point in the view-finding picture, and when the smooth zoom switching is performed on any point in the view-finding picture, a plurality of lenses included in the optical zoom module can be controlled to move correspondingly, and the light deflection assembly can move in the opposite direction according to the vector value from the any point to the current view-finding center position of the view-finding picture. In this way, the camera module can take any point appointed or automatically identified based on the view finding picture as a zoom center, then calculate the vector value of the any point and the current view finding center position as the operation basis of the movement of the light deflection component, so that the rotating motor of the light deflection component and the motor of the optical zooming component work simultaneously, the effect of smooth optical zooming of any point in the view finding picture can be completed, and when the optical zooming is ensured, the any point in the view finding picture can be taken as the zoom center of the view finding picture.
In some embodiments, the camera module is formed by a set of prisms (light deflecting components) capable of rotating around two axes (Pitch and Yaw) and a zoom lens component, wherein the two times of the rotation angle of the prisms is greater than or equal to the angular difference between the diagonal angle of view (first angle of view) of the view of the optical zoom module at the minimum magnification and the diagonal angle of view (second angle of view) of the view at the maximum magnification. For example: the Pitch can axially rotate a prism of +/-5 degrees, and is matched with a camera module of which the diagonal visual angle of a viewing picture under the minimum magnification is 40 degrees and the diagonal visual angle of the viewing picture under the maximum magnification is 20 degrees.
When the camera module works under the minimum magnification, the prism performs anti-shake processing (0-3 degrees), when the smooth zooming switching is performed on any point (expected framing center) in a framing picture under the minimum magnification, the lens group (a plurality of lenses) of the zoom lens assembly moves correspondingly, the prism performs reverse motion according to a vector from any point in the framing picture to the current framing center of the framing picture, and when the optical zooming is ensured, any point in the framing picture can become the center of picture zooming. Therefore, the problem of information loss of an object to be tracked caused by zooming of the visual angle during optical zooming can be solved, and smooth zooming is carried out at any position in a framing picture, so that the shooting effect is more diversified.
In some embodiments, the method may further comprise: in the process of shooting the view-finding picture, if the camera module is detected to move in 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 shooting a framing picture, 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.
