Abstract: A camera module includes: a lens module including a plurality of lenses disposed along an optical axis; a housing accommodating the lens module; and a reflection module disposed in front of the lens module, and including a reflective member configured to change an optical path, and a holder in which the reflective member is mounted. The reflection module is rotatably disposed on a first axis and a second axis perpendicular to the optical axis. A first position sensor configured to sense a position change of the reflection module with respect to the first axis is disposed in the housing. A second position sensor configured to sense a position change of the reflection module with respect to the second axis is disposed in the housing. A sensitivity of the first position sensor is different from a sensitivity of the second position sensor.
