Abstract
An actuator of a camera module includes a magnetic body disposed on one side surface of a lens barrel, a driving coil, and a driving apparatus. The driving coil faces the magnetic body. The driving apparatus is configured to drive the driving coil in one of a linear driving scheme and a pulse width modulation (PWM) driving scheme based on an external illumination information in an illumination signal and move the lens barrel in a direction perpendicular to an optical axis direction.
