  • Patent number: 7782492
    Abstract: It is disclosed a method of generating mapping data for converting first image data adapted to be reproduced by a first imaging device having a first gamut to second image data adapted to be reproduced by a second imaging device having a second gamut which is different from the first gamut. A third gamut is determined so as to include the first gamut and the second gamut. The first gamut is extended to the third gamut to obtain first mapping relationships. The third gamut is compressed to obtain second mapping relationships. It is generated mapping data associating first colors included in the first gamut with second colors included in the second gamut by way of the first mapping relationships and the second mapping relationships.

  • Patent number: 7777914
    Abstract: An image-processing device adapted to the increased types of color printers without excessive manpower includes a common color correction unit, which carries out a conversion (color correction or customization) common to the models of color printers. Therefore, the method for conversion does not need to be changed depending on the type of color printer. As a result, color correction mode-adapted LUTs, stored color correction LUTs, and light source correction LUTs needed for the common color correction unit do not increase even if the models of color printers increase, and common LUTs can be used. Consequently, the manpower needed to fabricate the color correction mode-adapted LUTs, stored color correction LUTs, and light source correction LUTs does not increase even if the models of printers increase, so that the image-processing device can be adapted to an increase of the models of color printers without excessive manpower.
