1. A rear view mirror system for motor vehicles comprising:
an exterior rear view mirror device, comprising,
a rear view mirror base configured to be attached to a vehicle,
a rear view mirror head attached to the rear view mirror base, and
a mirror element arranged in the rear view mirror head, wherein the mirror element is completely transparent or translucent from inside of the rear view mirror head,
wherein an actuator enables an orientation of the mirror element to be adjusted by rotating and/or tilting one or more of the mirror element and the rear view mirror head
wherein a camera is arranged inside the rear view mirror head behind the mirror element for recording a camera view (CV) with a first viewing angle of the surroundings of the vehicle at least through the mirror element, wherein the camera has a fixed position relative to the vehicle and does not move together with the mirror element such that the rear view mirror device enables movement of the mirror element relative to the camera,
wherein a control unit processes the camera view (CV) received from the camera to provide a monitor view (MV) with a second viewing angle being smaller than the first viewing angle being displayed on a monitor to provide the monitor view (MV) to a driver of the vehicle,
wherein the control unit is adapted to extract the monitor view (MV) from the camera view (CV) as part of the camera view (CV), with the monitor view (MV) being kept constant regardless on the camera orientation, and
wherein the control unit is adapted to re-calibrate the camera with respect to the orientation of the mirror element relative to the camera.
