摘要：The gray axis of an input apparatus is shifted so as to match the gray axis of anoutput apparatus. Each data on a plane of equal lightness located in the Gamut of theinput apparatus is shifted in the same direction in accordance with the shift of the grayaxis by an amount of shifting smaller in proportion to greater distance from the gray axis.Therefore, the image is not governed by the chromaticness in the shifting direction evenif the gray axis is shifted. Points located outside the Gamut of the output apparatus iscompressed-converted into points within the Gamut (surface) where color difference isminimized while maintaining the lightness. A desired image is reproduced withoutinversion in the lightness after Gamut compression between data.
