Abstract
An actuator of a camera module includes: driving wires to drive a lens barrel in a direction perpendicular to an optical axis; a driver to provide a driving signal in the form of a pulse to the driving wires; and a controller to generate a control signal based on a target position of the lens barrel and a present position of the lens barrel, to control the driver, and to generate resistance offsets between the driving wires based on resistance slope of each of the driving wires.
