Patent ID: 7697176

Claim:
A method for performing chromatic adaptation, comprising: performing maximum chromatic corrections to tristimulous color values in the vicinity of white and neutral colors; performing minimum chromatic corrections to tristimulous color values in the vicinity of non-neutral colors; wherein said corrections are piecewise liner in a tristimulous color space; wherein the corrections to the tristimulous color space are performed in a Red-Green-Blue (RGB) color space that comprises a linear transformation of the tristimulous color space; and further comprising: applying a correction factor, α, which is equal to zero for all colors except colors near yellow, the correction factor is determined as follows: α=α 0 G/R for R≧G≧B; α=α 0 R/G for G≧R≧B; α=0 for B≧R and B≧G; and wherein said correction factor is calculated on a controller.
