1. An image processing device for processing image data from an image sensor with a regular pixel arrangement and an associated color filter with Bayer pattern having a first color component green, a second color component red, and a third color component blue, wherein the image processing device carries out image processing operations by using image data from a predetermined environment comprising several pixels with respect to a pixel of interest, wherein the image processing operations perform a shift of the color value parallel to a non-color line of the color space by addition of an identical structural value to all color components of the image data, and wherein the image processing operations determine based on image data of the first color component green of the environment a correction value which is added to the image data of the second color component red and the third color component blue with a different respective sign.
