Claim:
1. A camera module, the camera module comprising: a stator; a mover disposed in the stator and including at least one lens; a cover surrounding the stator and the mover; a base fixed to the stator; an elastic member elastically supporting the mover; an actuator including a first driving unit formed at the mover and a second driving unit formed at the stator for driving the mover using an electromagnetic interaction with the first driving unit; an actuator driving unit controlling the actuator to move the mover to a forward direction or to a backward direction opposite to the forward direction; and a direction bit allocated in the actuator driving unit, wherein the mover is distanced from the cover by a first gap and from the base by a second gap at an initial position when no current is applied to the actuator; and wherein the direction bit comprises a datum defined as the forward direction or the backward direction, and control data comprises a control bit added to the direction bit, such that the mover is driven to the forward direction with decreasing the first gap or to the backward direction with decreasing the second gap through the direction bit according to the control data.
