Patent attributes
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.
