Abstract
A camera module actuator includes, a magnet, a coil, a driver, and a position estimating processor. The coil is disposed to face the magnet. The driver is configured to move the magnet by applying a driving signal to the coil. The position estimating processor is configured to estimate a position of the magnet from an oscillating signal. A frequency of the oscillating signal varies according to a movement of the magnet.
