摘要 |
Color of an information-input apparatus not in the color gamut of an information-output apparatus is converted to color inside a color gamut of the information-output apparatus and on a half-line which passes through a point which corresponds to color of an information-input apparatus taking a convergence point as an endpoint. The convergence point may any one of a point where saturation takes a value of 0, a point of an average value of a color gamut of an information-input apparatus, a point of a central value of a color gamut of an information-input apparatus, or a point of a weighted value of a color gamut of an information-input apparatus.
