Abstract
A color conversion method and a color conversion apparatus are provided in which in performing a color conversion, an efficient color conversion table memory is efficiently used and a given color conversion is performed over the entire color space by use of the output values at a plurality of vertices of a unit interpolation solid with continuity being ensured to thereby eliminate the necessity for a color conversion table other than the color conversion table for the input color space. A signal line PNTSL is provided in a solid area determiner and a solid interpolation calculator, and the output of a color conversion table memory and the calculation used for an interpolation of a given solid and an interpolation of a divisional solid obtained by dividing the given solid such as a triangular prism interpolation and a tetrahedron interpolation are switched to those for any one of the interpolations.
