Abstract
The CiMiYi signals of input CiMiYiKi signals are converted into CoMoYo signals of CoMoYoKo signals by using three-dimensional LUT color converting devices. The Ki signal of the input CiMiYiKi signals is subjected to gradation conversion to obtain the Ko signal of the CoMoYoKo signals by using a one-dimensional LUT.
