Abstract: Provided is a color compensation device of an electronic device including a first color converter, a parameter generator, an operator, and a second color converter. The first color converter receives an image signal, converts the image signal into initial tristimulus values based on a basic look-up table, and generates a conversion look-up table using the basic look-up table. The parameter generator extracts 2N number of representative parameters from the conversion look-up table and generates N number of compensation parameters on the basis of the 2N number of representative parameters. N is a natural number. The operator generates compensated tristimulus values at each gray scale using the N number of compensation parameters, generates a compensation look-up table, and converts the initial tristimulus values into the compensated tristimulus values using the compensation look-up table. The second color converter converts the compensated tristimulus values into a compensated image signal.
