APPARATUS FOR DRIVING AUTO FOCUSING AND CONTROLLING METHOD THEREOF

摘要

According to the present invention, an auto focusing driving circuit comprises: a motion sensor outputting motion data for a motion of a camera module; a processor generating a control signal to control a focus of an object based on the motion data; and an optical driver moving a lens in certain direction based on the control signal. Provided is an auto focusing driving apparatus detecting driving directions and an amount of movement of the lens, based on an output data of the motion sensor corresponding to the movement of the object, to remove problems caused by performing an existing auto focusing method.
