The imaging system has two lenses coupled together, wherein both lenses face different sides of the device body. Each lens has a separate image sensor; for example, the first lens is for the front side camera and the second lens is for the back side camera. A single actuator moves both lenses simultaneously. Depending on the imaging direction, either the front side image sensor or the back side image sensor is activated and an image is received through the corresponding lens system. The actuator generates autofocus or image stabilization functions for both cameras.
