Color conversion look-up table generating device, color conversion look-up table correction method, and storage medium

摘要

A color conversion look-up table generating device of the present invention includes a converting unit configured to convert an actual color material value of a target grid point in the color conversion look-up table and an actual color material value of a neighbor grid point of the target grid point into virtual color material values, and a correcting unit that corrects the actual color material value of the target grid point on the basis of a virtual color material amount of the target grid point and a virtual color material amount of the neighbor grid point, wherein the virtual color material value is an output value of a virtual color material that absorbs only light of spectral reflectance in each of divided blocks in a case in which spectral reflectance of the actual color material is divided into n (n is an integer of 3 or more) blocks.
