A camera, camera lens, image sensor, and a shape memory alloy (SMA) motor are stacked within a frame. The SMA motor is located on an out-light side of the camera lens. The image sensor is located between the lens and the SMA motor and is fastened to the SMA motor. The SMA motor is configured to actuate the image sensor to shift on a plane perpendicular to an optical axis of the camera lens. The camera may be associated with an electronic device.
