Method of correcting color image data according to correction table

The technique of the present invention allocates a coordinate point of target image data on a color space to multiple lattice points in a color conversion table and reads data stored at the multiple lattice points. This arrangement ensures high-speed color conversion of the target image data. The procedure selects multiple lattice points and allocates a coordinate point of one target image data to the selected multiple lattice points. The procedure then specifies color-converted image data corresponding to the target image data, based on data read from the multiple lattice points. A first application allocates the target image data to the coordinate points of the multiple lattice points arbitrarily selected in the vicinity of the target image data. A second application allocates N-dimensional target image data to the coordinate points of multiple but not greater than N lattice points. A third application calculates an arithmetic mean of the data read from the multiple lattice points to specify the color-converted image data. Any of these arrangement effectively enhances the conversion accuracy without increasing the size of the color conversion table.
