20110142433Drop detection using lens position sensing of camera module - Systems and methods to achieve an auto-focus camera with a movable lens barrel having a mechanic shock detection capability combined with a re-initialization of the camera module have been disclosed. This re-initialization may comprise moving the lens barrel displaced by the shock to a home position.
