Abstract: 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.

Abstract: 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.

Abstract: A camera module includes a housing; a lens module provided in an internal space of the housing to be movable in an optical axis direction, and including at least one lens therein; a magnet disposed in the lens module; and position detection sensors to detect a position of the magnet. One or more of the position detection sensors are disposed to face a first polarity of the magnet and one or more of the position detection sensors are disposed to face a second polarity of the magnet different than the first polarity.
