Abstract
A method for independently controlling hue or saturation of individual colors in a real time digital video image, without affecting the hue or saturation of any other color in the same real time digital video image. Includes selecting a uniquely defined independent color hue control delta value or independent color saturation control delta value, where the delta value represents an extent or magnitude of change in hue or saturation, respectively, of the selected individual color, and, separately evaluating uniquely defined independent color hue control functions or independent color saturation control functions, using input image pixel values of the plurality of input image pixels identified as having the individual color in the real time digital video input image whose hue or saturation was selected to be independently changed, and using the corresponding selected independent color hue control delta value or the corresponding selected independent color saturation control delta value, respectively, for forming and displaying a corresponding plurality of output image pixels having the individual color whose hue or saturation was selected to be independently changed.
