Abstract

In an output profile representing a correspondence relationship between device independent coordinate values and second coordinate values in a second device dependent color space, a color conversion table used to convert the device independent coordinate values into the second coordinate values is defined as a first conversion table, and the device independent coordinate values at the adjustment point are defined as to-be-adjusted PCS values. In optimization, an optimization process including an element making provisional color values closer to an adjustment target is executed, the provisional color value being acquired by a conversion, in accordance with the first conversion table, of provisional PCS values resulting from a change in the to-be-adjusted PCS values, thus acquiring an optimal solution for the device independent coordinate values corresponding to the adjustment target.
