Abstract
An apparatus to control a position of a camera module includes a magnetic member, a coil, a driver, a signal extractor, and a position detector. The magnetic member is disposed on a lens barrel of the camera module. The coil is disposed opposite to the magnetic member. The driver is configured to provide a position confirmation signal to the coil. The signal extractor is configured to extract a specific frequency component from a signal of the coil including the position confirmation signal and output a detection signal. The position detector is configured to provide a position signal corresponding to a position of the magnetic member based on the detection signal.
