Abstract
A camera module actuator is described including a magnet, a coil disposed to face the magnet, and a driver configured to apply a driving signal to the coil to move the magnet. The camera module actuator also includes a detector configured to detect a position of the magnet from a change in inductance of the coil, based on the movement of the magnet.
