Abstract: The present invention relates to a portable electronic device comprising: a housing; a camera unit (1), which can be rotated relative to the housing, for capturing an image;—electromechanical detection means for detecting a rotational position of the camera unit, wherein the electromechanical means comprise a cam (3) attached to the camera unit and a switch, said switch comprising two blades (4, 5) attached to the housing and surrounding the cam, the cam being adapted to hit one of the two blades when the camera unit is rotated so that the two blades are no longer in contact.

Abstract: The present invention relates to a portable electronic device comprising: a housing; a camera unit, which can be rotated relative to the housing, for capturing an image; magnetic detection means for detecting a rotational position of the camera unit; image processing means for modifying the image captured by the camera unit depending on the rotational position detected by the magnetic means. The magnetic detection means comprise a magnetic transmitter attached to the camera unit and a magnetic receiver attached to the housing.
