Claim 16:
17. The color gamut mapping method as claimed in claim 1, wherein the step of obtaining the grayscale values of the second mapping point according to the color coordinates and the luminance value of the second mapping point comprises:
calculating grayscale values of a plurality of mapping points in a color gamut triangle corresponding to the original color gamut by selecting red, green, and blue (R, G, and B) of the original color gamut at different grayscales, respectively, to establish a mapping lookup table from the original color gamut to the target color gamut; and
obtaining the grayscale values of the second mapping point in the target color gamut according to grayscale values of the original point in the original color gamut and the mapping lookup table.
