Abstract: An actuator of a camera module includes a magnet, a coil facing the magnet, a driver configured to apply a driving signal to the coil to move the magnet in a direction, and a position estimator. The position estimator is configured to convert an oscillation signal into a digital signal in a delta sigma modulation scheme, and estimate the position of the magnet from the digital signal. A frequency of the oscillation signal varies based on a position of the magnet.
