ABSTRACT:
A method of converting image data from L*a*b* color space into CMYK color space by using a three-dimensional direct mapping table employs only data of lattice points existing within the color space. 8-point interpolation is used when all the lattice points constituting a lattice component containing input data are included in the color space, while another interpolation processing (e.g. 4-point interpolation) is employed for a lattice component partially existing outside the color space by using only lattice point data within the color space. Enhancement of precision in color conversion is thus achieved.
