Abstract:
1. An image stabilizing camera system comprising: a camera module, the camera module comprising a movable auto-focus (AF) unit, a frame having a receiving cavity defined therein, an electromagnetic driving unit, and an elastic member, the movable AF unit comprising a voice coil motor, the receiving cavity receiving the movable AF unit therein, the elastic member being disposed on a top end of the movable AF unit, and the elastic member interconnected between the movable AF unit and the frame, thereby suspending the movable AF unit in the receiving cavity; a motion sensor for detecting a movement of the image stabilizing camera system; a central processor electrically connected to the motion sensor, the central processor being configured for computing a compensate movement adjustment for the movable AF unit based on a motion detection result of the motion sensor, and generating an image stabilizing signal associated therewith; and a current controller electrically connected to the central processor and the electromagnetic driving unit, the current controller being configured for receiving the image stabilizing signal, and controlling the electromagnetic driving unit to drive the movable AF unit to move relative to the frame, thereby compensating a movement of the image stabilizing camera system.
