Method for independently controlling hue or saturation of individual colors in a real time digital video image
First Claim
1. A method for independently controlling hue or saturation of individual colors in a real time digital video image, comprising the steps of:
- (a) receiving and characterizing the real time digital video input image featuring input image pixels;
(b) selecting to independently change the hue or the saturation of an individual color in the real time digital video input image, by selecting an independent color hue control delta value or an independent color saturation control delta value, respectively, wherein said independent color hue control delta value represents an extent of change in the hue of said selected individual color and wherein said independent color saturation control delta value represents an extent of change in the saturation of said selected individual color;
(c) identifying a plurality of said input image pixels having said selected individual color in the real time digital video input image with the hue or the saturation selected to be independently changed, by performing arithmetic and logical operations using input image pixel values of each said input image pixel of the real time digital video input image;
(d) determining corresponding output image pixel values for each of said plurality of said input image pixels identified as having said selected individual color in the real time digital video input image with the hue or the saturation selected to be independently changed, by separately evaluating independent color hue control functions or independent color saturation control functions, respectively, using said input image pixel values of said plurality of said input image pixels, and using corresponding said selected independent color hue control delta value or said corresponding selected independent color saturation control delta value, for forming a corresponding plurality of output image pixels having said selected individual color with the hue or the saturation selected to be independently changed; and
(e) displaying a real time digital video output image including said corresponding plurality of said output image pixels having said selected individual color with the hue or the saturation selected to be independently changed in the real time digital video input image, whereby the hue or the saturation of said selected individual color in the real time digital video input image has been changed without affecting the hue or the saturation of any other individual color in the real time digital video input image.

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.
