摘要： A camera module includes a lens module; a first frame accommodating the lens module; a second frame accommodating the first frame; a third frame accommodating the second frame; and a housing accommodating the third frame. The lens module and the first frame are configured to rotate with respect to the second frame around an optical axis. The lens module, the first frame and the second frame are configured to rotate with respect to the third frame around a first axis that is perpendicular to the optical axis. The lens module, the first frame, the second frame, and the third frame are configured to rotate with respect to the housing around a second axis that is perpendicular to both the optical axis and the first axis.

摘要： A sensing unit of a camera module includes a detection target provided on a side surface of a lens module, one or more sensing coils disposed to face the detection target, and a calculator. The calculator may determine a displacement of the detection target translated in any of an optical axis direction, a first direction perpendicular to the optical axis direction, and a second direction perpendicular to the optical axis direction, based on inductances of the one or more sensing coils.

摘要： An actuator includes a magnet, a driving coil facing the magnet, a driver, and a position calculation processor. The driver is configured to move the magnet in at least one of an optical axis direction and a direction perpendicular to the optical axis by applying a driving signal to the driving coil. The position calculation processor includes sensing coils, and is configured to calculate a position of the magnet according to inductance levels of an inductor of the sensing coils. The inductance levels vary according to movements of the magnet.
