Abstract:
1. A color conversion apparatus to selectively adjust input colors, comprising: a first color space converter to convert an input color signal to a color signal in a color space that is based on a luminance component and a chromaticity component; a region determiner to determine whether the input color signal of each pixel is in a particular gamut to which the color is converted, among gamuts of a color reproducing apparatus; a color converter to perform a color conversion of the input color signal according to a shape of the particular gamut using a reference color, which is a reference of a conversion amount of the input color signal and present in the particular gamut, and a target color which is converted from the reference color; and a second color space converter to convert the input color signal, which is converted to the color space having the luminance component, to a color signal in a color space displayable on the color reproducing apparatus.
