ABSTRACT:
Interpolation processing is applied to the output of a look-up table in which a correlation between color-separation signals and density signals ideal for these color-separation signals are stored, with a quantization error produced when quantizing the color-separation signals being adopted as an interpolation coefficient. The quantization and the interpolation processing are executed in a uniform color space.
