摘要：The technique of the present invention allocates a coordinate point of targetimage data on a color space to multiple lattice points in a color conversion table andreads data stored at the multiple lattice points. This arrangement ensures high-speed
color conversion of the target image data. The procedure selects multiple lattice pointsand allocates a coordinate point of one target image data to the selected multiple latticepoints. The procedure then specifies color-converted image data corresponding to thetarget image data, based on data read from the multiple lattice points. A first applicationallocates the target image data to the coordinate points of the multiple lattice pointsarbitrarily selected in the vicinity of the target image data. A second application allocatesN-dimensional target image data to the coordinate points of multiple but not greaterthan N lattice points. A third application calculates an arithmetic mean of the data readfrom the multiple lattice points to specify the color-converted image data. Any of thesearrangement effectively enhances the conversion accuracy without increasing the size ofthe color conversion table.
