1. An improved method for surveillance of an outside rearview mirror observation area of a motor vehicle, comprising:
- detecting the observation area with at least one image pick-up sensor element, the observation area having an angular range;
subdividing the detected observation area into two adjacent observation zones having unequal angular ranges, the two observation zones consisting of a first observation zone and a second observation zone, the angular range of the observation area being equal to the combined angular ranges of the two observation zones, the two observation zones being coextensive with the observation area; and
displaying an image of the first and second observation zones.

Abstract
The present invention relates to a method and a device for surveillance of the rearward observation area, specific to the outside mirror(s) of motor vehicles, in which the aforesaid observation area is divided into at least two observation zones (10, 20) that are detected using at least one image pick-up sensor element and the detected image is displayed on a display device (40) thus providing an improved rearward view with fewer gaps (blind spots), wherein the observation zones (10, 20) cover different angular ranges.
