  • IMAGE PROCESSING APPARATUS AND COMPUTER READABLE MEDIUM
    Publication number: 20110038533
    Abstract: An image processing apparatus includes a definition reducing section, a color region extracting section, a concealing image generating section and an image combining section. The definition reducing section, based on a received image, generates an image having a lower definition than the received image. The color region extracting section extracts a color region from the low definition image generated by the definition reducing section. The concealing image generating section, based on the color region extracted by the color region extracting section, converts the color region into a concealing region for concealing a part of the received image and, generates a concealing image including the concealing region. The image combining section combines the received image with the concealing image generated by the concealing image generating section.

  • SYSTEMS AND METHODS FOR BUILDING A COLOR LOOKUP TABLE FOR A PRINTER
    Publication number: 20110038010
    Abstract: Color separation systems and methods improve color constancy and smoothness of a color lookup table (LUT) for a printer. A plurality of nodes of the LUT may be defined in calorimetric space, and the nodes out of the printer gamut may be mapped to the printer gamut surface. All possible colorant combinations are then determined that produce each node in the LUT in a device independent color space based on an inversion of the spectral based printer model. Next, a specific image quality metric combination based on a color inconstancy index (CII) and a gray component replacement (CGR) strategy is defined. And a colorant combination is determined for each and every node in the LUT based on this metric. A smoothing filter may be used to smooth the lookup table.
