ABSTRACT:
In creating a color conversion table, search time for searching a point at which a color difference with a target color corresponding to a grid point is minimum can be reduced effectively. In a predetermined grid point constituting a second pre-color processing table, a post-RGB value of a target color of the grid point is determined by interpolation computation using a first pre-color processing table created beforehand. An interpolation operation using each grid point data of a plurality of grid points in the neighborhood in the table is executed, thus the post-RGB value of an object grid point is determined. Next, a neighboring region of the obtained post-RGB value is set, and a post-RGB value of most approximate to the target color in the neighboring region is determined as grid point data of the object grid point.
