Abstract:
1. A color correction method for correcting the colors of photographic images represented by image data, said image data defining color values, comprising the steps of: a) providing a set of distributions of color values in a color space, b) selecting one or more reference parts of the image to be corrected, each of said one or more reference parts having at least one color value; c) assigning one of said set of distributions to each selected reference part of said one or more reference parts; d) determining a transformation for transforming the at least one color value of the one or more reference parts such that the transformed at least one color value at least approximately matches the color values of the one or more assigned distributions or matches the color values of those distributions better than the at least one untransformed color value; and e) transforming the color values of the image data by means of the determined transformation to achieve a corrected image.
