A method of converting a color gamut includes generating first color gamut conversion lookup tables for gradations, applying each of the first color gamut conversion lookup tables to a red-green-blue (RGB) value of a comparison pattern to generate a compensation RGB value for each of the first color gamut conversion lookup tables, determining an expected luminance according to the compensation RGB value, comparing the expected luminance with a target luminance in the comparison pattern, selecting at least one of the first color gamut conversion lookup tables as a second color gamut conversion lookup table according to a comparison result, and converting the color gamut of an image displayed on a display panel using the second color gamut conversion lookup table.
