Abstract: A state of a rear vehicle light is detected. A camera system integrated in a vehicle generates an image of an environment in front of the vehicle. An evaluation unit connected to the camera system detects at least one vehicle contained in the image, defines an image range associated with said vehicle, and divides the image range into sub-ranges comprising at least a left sub-range and a right sub range. A segmentation of the sub-ranges into image segments is performed by way of the evaluation unit on the basis of brightness values of points contained in said sub-ranges. At least one brightest image segment is extracted from each of said sub-ranges, and the extracted image segments are checked for whether they can be associated with a particular vehicle light in an ON state.

Abstract: The invention relates to a method and a device for compensating a roll angle (?) when operating a camera-assisted driver assistance system in a motor vehicle. A camera takes a first image (32) and the coordinates of at least two characteristic points (30) of the first image (32) are determined. With the camera a second image (33) is taken and the coordinates of the two characteristic points (30) in the second image (33) are determined. Depending on the determined coordinates of the characteristic points (30) in the first and the second image (32, 33), two actual displacement vectors (IV—1, IV—3) are determined, each of which is representative for a displacement of the characteristic points (30) from the first image (32) to the second image (33) in an image plane of the camera.
