Abstract
In a method for operating a dazzle protection system for a vehicle, an image of the head of a vehicle occupant is acquired via a video sensing device and is compared with a reaction pattern typical of dazzling.
Claims20
A method for operating a dazzle protection system for a vehicle, the method comprising:
- inferring a dazzle intensity and direction affecting a vehicle occupant from a comparison of an image of a head or a head part acquired via a video sensing device with a reaction pattern typical of dazzling;
- wherein the vehicle has the video sensing device, which is directed at the head of the vehicle occupant, an evaluation device for evaluating received signals, and at least one dimming apparatus to at least partially darken an interior of the vehicle, and
- wherein dazzle intensity and direction is inferred from one of:
- i) a comparison of the local brightness distribution, or ii) a contrast of a face region with respect to an eye region.

A method for operating a dazzle protection system for a vehicle, the method comprising:
- sensing the head or the head part of a vehicle occupant via a video sensing device, wherein the vehicle has the video sensing device, which is directed at the head of the vehicle occupant, an evaluation device for evaluating received signals, and at least one dimming apparatus to at least partially darken an interior of the vehicle;
- and
- comparing the head or the head part of the vehicle occupant sensed via the video sensing device with an associated reaction pattern;
- inferring a dazzle intensity and direction affecting a vehicle occupant based on the comparison;
- and
- at least partially darkening an interior of the vehicle via the least one dimming apparatus based on the inferring;
- and
- wherein the dazzle intensity and direction is inferred from one of:
- i) a comparison of the local brightness distribution, or ii) a contrast of a face region with respect to an eye region.

A dazzle protection system, comprising:
- a video sensing device directed at a head of a vehicle occupant;
- an evaluation device to compare the head or part of the head sensed via the video sensing apparatus with an associated reaction pattern, and to infer a dazzle intensity and direction affecting the vehicle occupant based on the comparison;
- and
- at least one dimming apparatus to at least partially darken an interior of the vehicle, the evaluation device controlling the at least one dimming apparatus based on an inferred dazzle intensity and direction;
- wherein the dazzle intensity and direction is inferred from one of:
- i) a comparison of the local brightness distribution, or ii) a contrast of a face region with respect to an eye region.
