Claim:
1. A data processing device comprising: a first reference value generator which generates a first reference value corresponding to a ratio of a chromatic color using image signals or first image signals obtained by gamma-compensating the image signals; a white generator which generates a white image signal and second image signals using the first image signals and generates a second reference value corresponding to an amount of a white data in use; a third reference value generator which generates a third reference value using a first color coordinate, a second color coordinate, the first reference value and the second reference value, wherein the first color coordinate corresponds to a color coordinate of the second image signals, and the second color coordinate corresponds to a color coordinate of the white image signal; and a gamut mapper which maps the second image signals to a color coordinate corresponding to the third reference value to generate third image signals, wherein the third reference value is set by adding the first color coordinate to a value, which is obtained by multiplying the first and second reference values by a value, which is obtained by subtracting the second color coordinate from the first color coordinate.
