Aperture module and camera module including the same

A camera module comprising:

• a lens barrel;
• an actuator configured to drive the lens barrel in a direction perpendicular to an optical axis of the lens barrel;
• and
• an aperture module configured to adjust an amount of light incident in the lens barrel,
• wherein the aperture module comprises an aperture coupled to the lens barrel, a magnet disposed on one side of the aperture, a coil disposed opposite to the magnet, a position detector configured to detect a position of the magnet and to generate a feedback signal, and a driver configured to compare an input signal indicating a target position of the magnet with the feedback signal, to calculate an error value, and to generate a driving signal based on the calculated error value, and
• the driver is configured to compare a current position of the lens barrel with a neutral position of the lens barrel to generate a compensation signal and to compensate for one of the input signal and the feedback signal based on the compensation signal.
