Abstract
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for three sub-color correction based on two-dimensional graphs. In an aspect, a method includes obtaining an image to be shown on a display, determining three sub-color values of a particular pixel in the image, including a first sub-color value for a first sub-color, a second sub-color value for a second sub-color, and a third sub-color value for a third sub-color of the particular pixel, obtaining a representation of a two-dimensional graph of color-correction curves, selecting a selected color-correction curve to use to correct the first sub-color value based on both the second sub-color value and the third sub-color value, determining a corrected first sub-color value based on the first sub-color value, and outputting the image using the corrected first sub-color value instead of the first sub-color value.
