Abstract
A method for improving the driver assistance function, in particular of driver assistance systems based on video images recorded from a vehicle, and a corresponding device for that purpose made up of a camera and processing unit. To improve the function during rain, the passing of a windshield wiper through the camera image be used to classify individual images and/or portions of images as being of higher or lower quality, in order to improve the quality of the images from the camera. The images from camera are intended to be used for automatic driver assistance systems.

25. A device for processing image information recorded from a vehicle, comprising:
-
at least one camera; and at least one processing unit for subdividing the image information from the camera into individual image portions and performing a statistical calculation for each individual image unit; wherein the processing unit uses the data of the statistical calculation to decide whether at least part of the windshield wiper is present in the particular image unit and whether the quality of the image information is high or low, in particular whether the quality of the image information is higher or lower than a predefined threshold value.
