Abstract
A color conversion apparatus includes a hardware processor that obtains a scanner profile created on the basis of measured RGB values and corresponding measured colorimetric values of patches in a first color chart, and creates a table including correction amounts of RGB values, each according to the level of flare estimated for a patch and each associated with an RGB-value difference and a patch-size difference, on the basis of RGB values of patches in the first color chart and RGB values of patches in a specific chart. The specific chart is created by using a part of the patches in the first color chart with the RGB value or patch size being changed. The hardware processor further corrects measured RGB values of patches in a second color chart with the table, and convers the corrected RGB values into colorimetric values with the scanner profile.
