    Abstract: A camera cover glass unit comprises a cover glass, arranged to protect an image capturing unit of a camera and a cover glass frame arranged to hold the cover glass is disclosed. A resilient structure is mounted between the cover glass and the cover glass frame and allows the cover glass to move in relation to the cover glass frame. A first permanent magnet is attached to the cover glass, and a motor is arranged to rotate a second permanent magnet in relation to the first magnet, in order to achieve a time-variant magnetic field, such that the second magnet attracts and repels the first magnet to a varying degree, thereby causing the cover glass to move in relation to the frame.
