<P>PROBLEM TO BE SOLVED: To control how much saturation is expanded according to a color gamut of a liquid crystal panel or color characteristics of R, G, and B. <P>SOLUTION: A display drive circuit includes an initial color gamut vertex coordinate storage unit (211) capable of storing initial color gamut vertex coordinates, a user target color gamut vertex coordinate storage unit (212) capable of storing user target color gamut vertex coordinates, and a saturation expansion coefficient determination unit (210) determining an expansion coefficient of saturation data based on the initial color gamut vertex coordinates and user target color gamut vertex coordinates. Further, the display drive circuit is provided with an expansion unit (206) that expands saturation of the display data based on the expansion coefficient of saturation of display data. The expansion coefficient of the saturation data is determined based on the initial color gamut vertex coordinates and user target color gamut vertex coordinates, and the saturation of the display data is expanded based on it, so that how much the saturation is expanded can be controlled according to the color gamut of the liquid crystal panel. <P>COPYRIGHT: (C)2010,JPO&INPIT |
