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： A camera module includes a fixed portion, a movable portion configured to be moved relative to the fixed portion in an optical axis direction, at least two position detection sensors, and a magnet disposed to oppose the at least two position detection sensors in a direction intersecting the optical axis direction. The magnet includes an N-pole and an S-pole on a surface opposing the at least two position detection sensors and a neutral zone between the N-pole and the S-pole. The at least two position detection sensors are disposed such that at least one position detection sensor opposes one of the N-pole and the S-pole and at least one other positon detection sensor opposes the neutral zone when the movable portion is moved in the optical axis direction.

摘要： A camera module includes a housing accommodating a lens module and a carrier, a focusing unit including a first magnet disposed in the carrier and a first coil disposed on a first substrate on the housing, and a shake correction unit including a second magnet and a third magnet disposed in the lens module, and a second coil and a third coil disposed on a second substrate on the carrier. The first magnet and the first coil face each other in a first direction. The second magnet and the second coil face each other in the first direction, and the third magnet and the third coil face each other in a second direction. The second magnet and the second coil, and the third magnet and the third coil, move together in an optical axis direction by driving force generated by the first magnet and the first coil.
