摘要
The invention relates to a method for adapting a gamma curve (G2) of a camera system by providing an input image of an environmental region of a motor vehicle and correcting the input image to an output image based on a current gamma curve (G2), by determining at least one region of interest in the output image by an image processing device, by determining a minimum and a maximum pixel value within the at least one region of interest of the output image, wherein the minimum and maximum pixel values define a current output range of values, by calculating associated minimum and maximum input pixel values (A min , A max ) of the input image from the minimum and maximum pixel values using the current gamma curve (G2), wherein the minimum and maximum input pixel values (A min , A max ) define a preferred input range of values (36), by generating a new gamma curve (G2') by defining a new output range of values (35') to the preferred input range of values (36), such that the new output range of values (35') is greater than the preferred input range of values (36), and applying the new gamma curve (G2') as current gamma curve (G2) for a subsequent input image.
