Abstract: Apparatus and method for controlling auto focus of a camera module. A controller is configured to provide a signal comprising first frequency signal and second frequency signal to a moving coil, a fixed coil receiving the variable current or the variable voltage through the second frequency signal, calculate a focus position value based on the received variable current or the variable voltage and an image signal, and control a lens unit to move according to the calculated focus position value. The controller is further configured to receive the second frequency signal only during a specific time slot in order for the second frequency signal to not include noise due to OIS signal and apply the OIS signal to an OIS coil during the rest of a time slot of the second frequency signal.
