PROBLEM TO BE SOLVED: To solve the problem that conventionally it is not possible to evenly correct a color conversion table of a reading device in the entire color region even with a limited number of patches. SOLUTION: In order to correct a color conversion table, a color conversion table from a device-independent color space into a device-independent color space is newly prepared. A shift in read data between devices is reflected in a correction 3D-LUT and the color conversion table is corrected using the correction 3D-LUT. It is possible to correct the entire color region with a smaller number of pieces of data and with less time and effort than when a color conversion table is newly recreated.
