    Abstract: 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.

    Abstract: A terminal, comprising at least two front cameras located behind a display panel, wherein an area corresponding to a position of the at least one camera on the display panel is a first area, and other than the first area on the display panel is a second area, wherein each pixel unit of the first area and the second area respectively comprises a transparent portion and a non-transparent portion and a proportion of the transparent portion in the first area is greater than that of the second area. The terminal further comprises a processor configured to obtain N pictures taken by the at least two cameras, and process the N pictures by complementing the occluded areas based on pictures taken by the at least two cameras to obtain a picture in which the occluded area is completely or partially recovered.
