In a method for processing a generated digital endoscopy image of a patient, those pixels that depict a body region of a patient are determined as image points in the endoscopy image, in a processor. In the processor, a color value is derived for image point using the value of the associated pixel, and an area portion associated with each image point is derived for the color value. A color area is derived for each color value, as the sum of all area portions of the image points having that color value. An evaluation measure of the endoscopy image is then implemented in the processor using the respective color areas.
