Abstract (en)
[origin: WO2018202261A1] The invention relates to a method for removing flare caused by scattered light from an image of a vehicle camera. An image of the external surroundings of a vehicle is captured by means of a vehicle camera which is disposed in or on the vehicle. A curve (7) of a total intensity within the image is also determined, the total intensity being caused by desired light and scattered light which passes into the detection region of the vehicle camera. An approximation function (8) of a curve of a lower limit of the scattered light intensity is also estimated, and the estimated approximation function (8) is subtracted from the determined curve (7) of the total intensity. The image with corrected scattered light is provided.
