IMAGE PROCESSING SYSTEM AND METHOD FOR IMPROVED COLOR CONVERSION

A system and method for processing image data generates color image data from a scanned image, the color image data including RGB data, converts the RGB data to CMY data, and translates the CMY data for the pixel to CMYK data. A weighting coefficient is set for a pixel based on the values of the CMY data for the pixel. A particular region in which the pixel is located is identified as a black color region or a non-black color region. The value of the K data for the pixel is altered based on the weighting coefficient if the particular region is a non-black color region.
