Abstract
An image processing method for detecting the activation of brake lights of vehicles driving in front, which do not emit an additional or a changed modulated signal during the braking procedure, has been presented. For this purpose, an image sensor or an image sensor system is aligned to a point in front of the vehicle, the camera images are fed into a memory and a motor vehicle driving in front is identified by means of a pattern recognition method on the image; in addition, following the detection of the vehicle, image areas are determined which contain brake lights to a high degree of probability.

9. A method for detecting activation of brake lights of vehicles driving in front of a vehicle, whereby an image sensor or an image sensor system is aligned to a point in front of the vehicle, and camera images are fed into a memory, the method comprising:
-
detecting a vehicle driving in front by using a pattern recognition method on the image; after detecting a vehicle, determining image areas which contain a position of brake lights to a high degree of probability; and forming a differential image from two images which are recorded offset from each other in time, wherein when changes in brightness occur in relevant image areas, an activation of the brake lights is detected. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
