Abstract
A cleaning device (1) for cleaning a lens (8) of a camera (2), using a cleaning head (4), comprises drive means (6) for driving the camera or the cleaning head, which are able to generate a relative displacement of the cleaning head with respect to the camera between a passive position in which the cleaning head is positioned outside of the image-capturing field of the camera, and an active position in which the cleaning head extends facing the lens so as to allow cleaning liquid to be ejected towards the said lens. The device particularly comes into effect in the case of an application to the cleaning of a reversing camera installed in motor vehicles.

A cleaning device for cleaning a lens of a motor vehicle camera using a cleaning head, comprising:
- drive means for driving the camera or the cleaning head, which are able to generate a relative longitudinal displacement of the cleaning head with respect to the camera between a passive position in which the cleaning head is positioned outside of the image-capturing field of the camera, and an active position in which the cleaning head extends facing the lens so as to allow cleaning liquid to be ejected towards the lens.
A method for cleaning a motor vehicle camera, comprising
- cleaning the camera by ejecting liquid from a cleaning head;
- generating a displacement instruction to make the camera or the cleaning head move from a passive position in which the cleaning head is outside the field of the camera into an active position in which the cleaning head faces the camera;
- and
- generating an ejection instruction to make the cleaning head eject liquid when the head is in the active position.
