Abstract

A method for enhancing the quality of an image, in particular with respect to its contrast properties, comprises the step of calculating a histogram for an input image (S), equalizing the input image on the basis of the calculated histogram to obtain a corresponding histogram equalized image (S), wherein the histogram equalized image and the input image are merged/mixed/blended (S) to obtain an output image, wherein merging/mixing/blending is weighted (S) in dependency of the content of the input image and/or of other input image data relating to the input image. This makes it possible to further improve the quality of histogram equalized images.
