High speed color matching processing system and method

The high speed color matching treatment system and method is used in fast conversion of digital metaimage from RGB mode into CMYK mode. The system includes conversion pre-treating module to convert the RGB values of key words into CMYK color values, memory module to store the CMYK color values, conversion controlling module to receive the conversion starting command to start conversion, and extracting module to extract the key words in the RGB values of pixels in current digital image based on the conversion starting command, search corresponding CMYK color values in the memory module based on the key words and convert the RGB values into CMYK color values. The present invention has raised color matching treatment speed of digital metaimage, reduced occupied memory, less conversion operation, and high color keeping performance in most applications.
