ABSTRACT:
An uneven dividing unit unevenly divides an input gamut into divisions which have figures similar to one another. An output-value determining unit determines predetermined lattice-point output values relevant to the divisions. A division selecting unit selects a division among the divisions obtained through the uneven dividing unit, the selected division corresponding to given input color-image data. An interpolating unit interpolates final output values for the given input color-image data using the lattice-point output values relevant to the division selected through the division selecting unit. The uneven dividing performed by the uneven dividing unit is that eliminating lattice points, the lattice-point output values of which are not used in the interpolating performed by the interpolating unit.
