ABSTRACT:
A conventional color conversion apparatus was associated with a problem of generation of an achromatic component and reduction in the luminance.A color conversion apparatus according to the present invention generates new color data corresponding to color red of red, green and blue by means of matrix calculation using a first calculation term which is effective for just one of the hues of red, yellow, blue, green, cyan, magenta and yellow, and a second calculation term which is calculated from the first calculation term and which is effective for a predetermined inter-hue region included in at least one of inter-hue zones of red-yellow, yellow-green, green-cyan, cyan-magenta, and magenta-red, so that color conversion can be achieved without generation of an unnecessary achromatic component or reduction in the luminance.
