  • Patent number: 11778317
    Abstract: A method for macro photography includes acquiring a first image captured by a first camera and a second image captured by a second camera; and controlling a third camera to perform macro photography in response to no overlapping region between the first image and the second image. Further, the third camera at least has a macro photography function, there is an overlapping field between fields of view of the first camera and the second camera in response to photography distances of the first camera and the second camera being greater than or equal to a first photography distance, and the first photography distance is less than or equal to a macro photography distance set in the third camera.

  • Patent number: 11736799
    Abstract: A zoom control method is provided, including: determining a midpoint of a connecting line of touch points located on both sides of an object to be close-up; determining a pixel vector formed from the midpoint of the connecting line to a center point of a screen; converting the pixel vector into an angle vector based on a conversion relationship between a diagonal angle of view of a current focal length range and a diagonal pixel of an image sensor of a camera system; and controlling the object to be close-up being moved to the center point of the screen based on the angle vector.

  • Patent number: 11082597
    Abstract: A camera module includes a fixed bracket, a camera body and an anti-shake assembly. The camera body includes a lens and an imaging sensor corresponding to the lens. The camera body is provided with a movable connecting member on an external side surface thereof arranged along a circumferential direction of the lens, the fixed bracket is provided with a movable fitting member corresponding to the movable connecting member, and the movable fitting member is movably connected with the movable connecting member. The anti-shake assembly includes a space attitude sensor and a driving module electrically connected with the space attitude sensor. The driving module is configured to be fitted with the camera body and to drive the camera body to perform an anti-shake motion relative to the fixed bracket according to shaking information obtained by the space attitude sensor.
