Abstract
A method for exposure control for a camera system in a motor vehicle is provided. The camera system records a sequence of images of the surroundings of the vehicle using an optimal exposure time. The optimal exposure time is predetermined depending on the brightness of the surroundings or on the brightness of individual objects in the image. If the optimal exposure time is longer than a predetermined threshold value, at least one intermediate image is recorded using a short predetermined exposure time, i.e. an exposure time shorter than the optimal exposure time. At least two driver assistance functions are executed on the basis of the image data of the camera system. The image data recorded using the optimal exposure time is used for a first driver assistance system and the image data recorded using the short exposure time is used for a second driver assistance system.
