    摘要： Three-dimensional LUTs produce a lightness signal L* from input color signals C, M and Y. The three-dimensional LUTs are respectively provided for four divisional sections of an input color signal K. A three-dimensional LUT switching device judges to what section a current value of the input color signal K belongs. A selector selects one of the LUTs in accordance with a judgment result. Similar processing is performed for chromaticity signals a* and b*. According to another aspect of the invention, three-dimensional LUT color converters produce color signals L.sub.2 *, a.sub.2 * and b.sub.2 * based on only input color signals C, M and Y. A position in the L*a*b* space of the color signals L.sub.2 *, a.sub.2 * and b.sub.2 * has a deviation from a position of color signals L.sub.1 *, a.sub.1 * and b.sub.1 * to be output actually. Based on an input color signal K, a one-dimensional LUT produces a lightness signal L.sub.3 *, which corresponds to the deviation. A color signal combining means produces final output color signals L.sub.1 *, a.sub.1 * and b.sub.1 * based on the color signals L.sub.2 *, a.sub.2 * and b.sub.2 * and the lightness signal L.sub.3 *.

    摘要： A method of determining lattice point data of a look-up table for transforming input color coordinates into colorant coordinates of a color image output device, or of reconstructing the same by using a differentiable-continuous function. An input-output characteristic of the device is determined by using a differentiable-continuous function based on discrete transformation pairs, and coefficients of color transformation that uses a look-up table or a continuous function is determined based on the thus-determined differentiable-continuous function.
