COLOR GAMUT INFORMATION CREATING DEVICE, COLOR GAMUT INFORMATION CREATING METHOD, AND COLOR GAMUT INFORMATION CREATING PROGRAM

摘要

PPROBLEM TO BE SOLVED: To provide a color gamut information creating device, a color gamut information creating method, and a color gamut information creating program that can create color gamut information accurately representing a color gamut of a device while suppressing an increase in number of hue cross sections. PSOLUTION: In a hue cross-section angle determination process (S2), a hue angle of a peak of a convex hull to be generated is determined and a hue angle of a hue cross section 61 is determined based upon the determined hue angle of the peak of the convex hull when the convex hull indicative of a distribution range of colorimetric points projected on an a*b* plane. Consequently, the hue angle of the hue cross section on which a distribution of feature points is reflected can be determined, and the color gamut information accurately representing the color gamut of the device can be created without blindly increasing the number of hue cross sections 61.
