Abstract
A method of detecting skin tone pixels in an input image and adjusting color values thereof for an output image is disclosed. The method comprises determining for each of a plurality of pixels in an input image whether initial chromaticity values of each of said pixels lie within a skin tone area defined in a chromaticity plane. The method further comprises amending the initial chromaticity values of those pixels that have chromaticity values lying within said skin tone area to obtain amended chromaticity values for use in obtaining an output image.
