    • 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.
    • 公开了一种生成映射数据的方法,用于将适于由具有第一色域的第一成像装置重新适应的第一图像数据转换成适于由具有第二色域的第二成像装置再现的第二图像数据,该第二成像装置具有与第一色域不同的第二色域 色域 确定第三色域以便包括第一色域和第二色域。 第一个色域扩展到第三个色域以获得第一个映射关系。 第三个色域被压缩以获得第二个映射关系。 通过第一映射关系和第二映射关系,生成将包括在第一色域中的第一颜色与包括在第二色域中的第二颜色相关联的映射数据。

    • 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.
    • 适合于不需要过多人力的彩色打印机的增加类型的图像处理装置包括执行彩色打印机的模型共同的转换(颜色校正或定制)的公共颜色校正单元。 因此,根据彩色打印机的类型,不需要改变转换方法。 结果,即使彩色打印机的型号增加,普通颜色校正单元所需的颜色校正模式适配LUT,存储颜色校正LUT和光源校正LUT也不会增​​加,并且可以使用公共LUT。 因此,即使打印机的型号增加,制造色彩校正模式适配的LUT,存储的颜色校正LUT和光源校正LUT所需的人力也不会增加,使得图像处理装置可以适应于 彩色打印机的型号没有过多的人力。
