Portable electronic device and camera module

A camera module comprising:

• a housing;
• a rotation holder comprising a reflection member, and supported on an inner wall of the housing, wherein the reflection member is movable along a first axis, perpendicular to an optical axis and parallel to a bottom of the housing, and in a second axis direction, perpendicular to the optical axis and the first axis;
• a sensing magnet disposed on a side surface of the rotation holder, parallel to an optical axis direction;
• a driving magnet disposed on the side surface of the rotation holder and parallel to the sensing magnet and configured to provide driving force to move the rotation holder in the first axis direction;
• and
• a position detection sensor disposed in the housing configured to detect a change in position of the sensing magnet and the driving magnet, to sense the movement of the rotation holder in the second axis direction.

A camera module comprising:

• a housing;
• a reflecting member disposed in the housing, configured to reflect incident light to an optical axis, and one or more of rotate about a first axis perpendicular to the optical axis and rotate about a second axis perpendicular to the first axis and the optical axis direction;
• a magnet disposed on a side surface of the reflecting member parallel to the optical axis;
• and
• a position sensor disposed in the housing to one or more of face the magnet in the first direction and configured to detect a movement of the magnet in the second direction when rotation about the first axis, and face the magnet in the second direction and configured to detect a movement of the magnet in the first direction when rotation about the second axis.
