US 12,015,849 B2 · Camera module and electronic device

Abstract

A camera system includes a module frame, a camera lens, an image sensor, and an SMA motor that are stacked within the module frame. The camera lens is fixedly connected to the module frame, and the SMA motor is located on an out-light side of the camera lens. The image sensor is located between the camera lens and the SMA motor and is fastened to the SMA motor. The SMA motor is configured to actuate the image sensor to shift in a direction parallel to an optical axis of the camera lens. The SMA motor is further configured to actuate the image sensor to shift on a plane perpendicular to the optical axis of the camera lens.
