Color conversion-relative guidance manner and the color conversion-relative guidance device, and the relation of the color conversion

摘要

PPROBLEM TO BE SOLVED: To derive a color conversion relation highly accurately at high speed forwards and backwards in a color conversion relation deriving method or the like for deriving the color conversion relation between a first color space and a second color space. PSOLUTION: The color conversion relation deriving method is provided with an area forming step 91 of forming a plurality of areas 360 with which the inside of a first color space 300 is filled, a partial function deriving step 92 of deriving, for each area 360, a partial function indicating color conversion between coordinates within the areas 360 and coordinates in a second color space 400 by using the set of an arbitrary sample point 310 provided within the first color space 300 and a point within the second color space 400 corresponding to the sample point 310, and an entire function deriving step 93 of deriving an entire function representing a color conversion relation all over the first color space 300 by linking the partial functions within the areas 360 derived in the partial function deriving step 92.
