发明名称 COLOR CONVERSION TABLE GENERATION DEVICE AND PROGRAM, AND COLOR CONVERSION DEVICE AND PROGRAM
摘要 PROBLEM TO BE SOLVED: To convert a specific color without performing complicated processing nor depending upon variation of input signals. SOLUTION: In a color conversion table generation device, a specific color designation part outputs a specific color signal independent of a device, for example, a L*a*b signal when a specific color is designated by a user or the signal of a specific color is input. A specific color output value calculation part calculates CMYK signals corresponding to a L*a*b<SB>s</SB>signal indicating the specific color. A specific color LUT generation part extracts a plurality of lattice points being apexes of a cube including points in a CIELab color space of the L*a*b<SB>s</SB>signal of the specific color obtained by the specific color designation part and sets LUT values (output signal values) of all the extracted lattice points to values (CMYK<SB>s</SB>signals). That is, the same values (Y<SB>S</SB>, M<SB>S</SB>, C<SB>S</SB>, K<SB>S</SB>) are set to respective output signal values of 8 lattice points (g1, g2 to g8) of a standard LUT.
