COLOR CONVERSION LOOK-UP TABLE GENERATING DEVICE, COLOR CONVERSION LOOK-UP TABLE CORRECTION METHOD, AND STORAGE MEDIUM

摘要

The color conversion lookup table creation apparatus of the present invention converts the actual color material value of the target lattice point in the color conversion lookup table and the actual color material value of the grid points near the target grid point into a virtual color material value. a conversion unit that corrects the actual color material value of the target grid point based on the virtual color material amount of the target grid point and the virtual color material amount of the neighboring grid points, wherein the virtual color material value is , when the spectral reflectance of the actual color material is divided into n blocks (n is an integer greater than or equal to 3), it is an output value of the virtual color material that absorbs only the light of the spectral reflectance in each divided block.
