Automatic saturation adjustment

摘要

A method of correcting image saturation is performed by defining saturated colors in a chromaticity color space; and deriving an overall correction of the saturation of colors in the image using the defined saturation of these colors in conjunction with a table of corrections indexed by hue and lightness. This process has a unique attribute of being able to automatically decrease saturation in regions of an image where oversaturation is detected. I'd like not to specify the actual form of the correction until well down in the claims. We have things that work but they could probably be improved, so there's no point in tying oneself to these specifics. My references to preferred incarnations of various things should signpost that for you.
