Abstract:
Color-correcting a digital image comprising P pixels (P≧4) is presented. Each of the P pixels has a respective color. Color strengths of the P pixels are determined based at least on respective intensities, respective saturations, or both respective intensities and respective saturations of the P pixels. A subset of the P pixels less than all of the P pixels is determined. The pixels in the subset have respective color strengths in a range of respective color strength. All other pixels of the P pixels have respective color strengths outside of the range of respective color strengths. Color correction is determined for the P pixels based in part on the colors of the respective pixels in the subset which are the only pixels of the P pixels used for determining the color correction. The colors of the P pixels are corrected based on the color correction.
