Abstract
Method of compressing/extending a color reproducing space which compresses or extends chroma of a first color gamut in a same hue plane. The color reproducing method and apparatus produces a third transformation definition by transforming a first color gamut represented by a first transformation definition within a second color gamut represented by a second transformation definition such that the gradation is preserved, produces a fourth transformation definition by transforming a second gamut within the first color gamut such that gradation is preserved and produces a fifth transformation definition in the second transformation definition by providing an inverse transformation from the second transformation definition into the first transformation definition to the first color gamut and then produces a color reproduction target transformation definition for transformation from the first transformation to the second transformation definition by mixing the second color gamuts represented by the third transformation definition and the fifth transformation definition.
