Abstract
A method and apparatus for converting an input color space into a CMYK color space are provided. The method includes converting a color signal of a predetermined input color space into an sRGB color space, converting the color signal of the sRGB color space into an sRGB L*a*b* color space, and converting the color signal of the sRGB L*a*b* color space into a color signal of a printer-output CMYK color space (CMYKPrinter) using a lookup table.
Claims31
A method of converting an input color space into a CMYK color space, the method executed by at least one processor comprising:
- (a) converting a color signal of an input color space into an sRGB color space;
- (b) converting the color signal of the sRGB color space into an sRGB L*a*b* color space;
- and (c) converting the color signal of the sRGB L*a*b* color space into a color signal of a printer-output CMYK color space (CMYKPrinter) using a lookup table.
An apparatus for converting an input color space into a CMYK color space, comprising:
- a first conversion unit which converts a color signal of aninput color space into an sRGB color space;
- a second conversion unit which converts the color signal of the sRGB color space into an sRGB L*a*b* color space;
- and a third conversion unit which converts the color signal of the sRGB L*a*b* color space into a color signal of a printer-output CMYK color space (CMYKPrinter) using a lookup table.
