Abstract
An actuator of a camera module includes a position detector configured to generate a feedback signal based on a detected position of a lens barrel; and a driver configured to drive the lens barrel based on a difference between an input signal indicating a target position of the lens barrel and the feedback signal, wherein the driver includes a signal adjuster configured to calculate an offset between the target position of the lens barrel and an actual position of the lens barrel, and apply the input signal to a calibration function based on the offset to generate a calibrated input signal.
