Japanese Patent JP2011109287
Kind Code:

Abstract:

To provide color expression without having an uncomfortable feeling since chromaticity of each of skin color being memory color, sky blue (cyan) and green is shifted as an area on a chromaticity diagram expressed by three RGB primary colors is very large, in an image display device capable of expressing a wide gamut.

By a memory color determination part 53, a skin color correction gain generation part 54, and a memory color correction part 55, a color of which the chromaticity comes close to a six-axis primary color chromaticity side is displayed as an optimum memory color by increasing a white component to an original color without having an uncomfortable feeling. Similarly, a sky blue memory color is also determined by the memory color determination part 53, and the white component increased in an addition part 52 is subjected to correction for bringing the chromaticity coming close to a primary color close to a white side by a multiplier 55d by correction data being wide gamut display from a microcomputer to be replaced based on the memory color determination result to provide an output video signal.
