Abstract

A color conversion data generation device includes: an acquisition unit that acquires end point correction values for correcting a color of at least one end point of a RGB color space; an end point color correction value generation unit that corrects the color of the at least one end point using the acquired end point correction values, to generate end point color correction values; a normalization unit that normalizes an intermediate color in the RGB color space using a normalization coefficient; an interpolation unit that interpolates the normalized intermediate color using the generated end point color correction values by means of same interpolation characteristic as that of a 3D LUT circuit, to generate temporary correction values; and an inverse normalization unit that inverse-normalizes the generated temporary correction values using an inverse normalization coefficient defined according to the normalization coefficient, to generate correction values of the intermediate color.
