Zusammenfassung:	The embodiment includes a lens unit, a control unit for supplying a driving current for moving the lens unit, and a position sensing unit for detecting the position of the lens unit. The control unit supplies a driving current to move the lens unit in multiple divisions to the target position. According to the present invention, the overshoot of the driving current can be reduced, the oscillation of an actuator can be prevented, and the stable zooming and AF operations can be performed. 실시 예는 렌즈부, 렌즈부를 이동시키기 위한 구동 전류를 공급하는 제어부, 및 렌즈부의 위치를 감지하는 위치 센싱부를 포함하고, 제어부는 타겟 위치까지 상기 렌즈부를 복수 번 분할 이동시키기 위한 구동 전류를 공급한다.
