摘要： A camera module includes: a housing in which a lens module is accommodated; and a shake correction portion including first and second movable yokes mounted on the lens module and first and second coil portions disposed to oppose the first and second movable yokes, respectively. The first coil portion is configured to attract the first movable yoke in response to power being applied to the first coil portion. The second coil portion is configured to attract the second movable yoke in response to power being applied to the second coil portion.

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： A camera module includes a lens module including lenses and a reflecting module disposed in front of the lens module. The reflecting module is configured to change a path of light to direct the light toward the lens module. The reflecting module includes a holder in which a reflecting member configured to change the path of the light is mounted and a first housing supporting the holder. The holder is configured to slide with respect to the first housing to enable rotation of the reflecting member with respect to a first axis and a second axis.

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.
