摘要:
Provided is an image processing device. A first color space converting unit converts image data in an RGB colorimetric system, which has a color gamut wider than a color gamut of a liquid crystal panel into image data in an XYZ colorimetric system. A three-dimensional nonlinear color gamut converting unit performs conversion on tristimulus values of the XYZ signal. At this time, the image data is classified into four colors and converted respectively such that the first color is displayed in a color accurate to the inputted data, the second color is displayed such that saturation of the second color is increased, the third color is displayed using a color gamut of a predetermined range out of the color gamut of the liquid crystal panel, and the fourth color is displayed in a color corresponding to a boundary of the color gamut of the liquid crystal panel.
