摘要： A camera module includes a lens barrel; an actuator driving the lens barrel in a direction perpendicular to an optical axis; and an aperture module adjusting an amount of light incident in the lens barrel. The aperture module includes an aperture coupled to the lens barrel, a magnet provided on one side of the aperture, a coil disposed opposite to the magnet, a position detector detecting a position of the magnet to generate a feedback signal, and a driver comparing an input signal indicating a target position of the magnet with the feedback signal to calculate an error value and generating a driving signal according to the calculated error value. The driver compares a current position of the lens barrel with a neutral position of the lens barrel to generate a compensation signal and compensates for one of the input signal and the feedback signal based on the compensation signal.
