ABSTRACT:
Binary data corresponding to respective lattice point data addresses of a direct look-up table and indicating an inside or outside of a color reproduction range of an output device are retained. Based on the binary data, a judgment is made of whether an input color signal is located inside or outside the color reproduction range of the output device. A lattice point data address that is generated from the input color signal is compressed based on a result of the above judgment. The judging and compressing operations are repeated to generate lattice point data addresses so that they are located inside the color reproduction range of the output device.
