PURPOSE: A camera module is provided to move a lens holder to a target position based on a reference position, thereby precisely controlling the position of the lens holder. CONSTITUTION: A camera module includes a lens holder (200), an actuator, and a power supplying unit. The lens holder is moved to a reference position when being driven and moved to a target position after completing the movement to the reference position. The actuator moves the lens holder to an optical axis direction by applying power. The power supplying unit applies first power to the actuator when moving the lens holder from a free position to the reference position and applies second power to the actuator when moving the lens holder from the reference position to the target position. |
