A camera module diving driver according to an embodiment of the present invention can improve the response speed of a control system, by controlling a current value applied to an actuator in controlling autofocusing by using the velocity information and the position information of a lens module. Also, a camera module diving driver according to an embodiment of the present invention comprises a plurality of controllers with different parameters, selects one of the controllers according to the distance by which the lens module is required to move, and performs a control operation, thereby preventing a change in control performance in an autofocusing process. |
