Abstract
A color modulation method for a display includes: obtaining a group of original RGB data of a pixel of an image; calling a display look-up-table (LUT) to determine whether a group of RGB mapped data corresponding to the group of original RGB data is present in the display LUT; if in, performing color modulation using the group of RGB mapped data corresponding to the group of original RGB data; and if not in, using the group of original RGB data, a plurality of groups of selected RGB data, and a group of RGB mapped data corresponding to each group of selected RGB data in combination with a predetermined interpolation algorithm to calculate the group of RGB mapped data corresponding to the group of original RGB data, and then using the obtained group of RGB mapped data to perform the color modulation.
