GRADATION CORRECTION CURVE CREATING METHOD, GRADATION CORRECTION CURVE CREATING APPARATUS, AND GRADATION CORRECTION CURVE CREATION PROGRAM

摘要

PPROBLEM TO BE SOLVED: To create a gradation correction curve rightly reflected in a gray direction by correcting dispersion of measuring instruments in a gradation correction curve creating method or the like for creating the gradation correction curve for correcting a gradation of an image. PSOLUTION: A chromaticity value is not directly measured but a spectrum is measured and the spectrum 54 is corrected. Then, the chromaticity value is found based upon the corrected spectrum 55, and the gradation correction curve is created by using the chromaticity value thus found. PCOPYRIGHT: (C)2004,JPO
