Abstract
A color enhancement system with variable color saturation addresses issues of clipping of an output image by analysis and application of color correction to individual pixels. Encoded image data is received, and the elements are converted from a color space representation, such as RGB, into another color space where the individual picture elements are color corrected. The color correction is accomplished by application of a correction matrix. Once correction has been applied, the values are converted back to the original color space representation.
