    • A color gamut surface generating apparatus includes a vertex generating unit and a gamut surface generating unit. A device-dependent color space has axes of (i) four basic colors including black and (ii) at least one extra color which are used in color output by an output device. The vertex generating unit generates, in the device-dependent color space, vertices of each of sub-surfaces constituting a surface of a color gamut by selecting (a) at least one color gamut each of which is output by the output device using a combination of three of the basic colors and one, corresponding to each color gamut, of the at least one extra color, and (b) a color gamut which is output by the output device using the four basic colors. The gamut surface generating unit generates surface points existing on the surface of the color gamut constituted by the vertices
    • 色域表面生成装置包括顶点生成单元和色域表面生成单元。 依赖于设备的色彩空间具有(i)四种基本颜色(包括黑色)和(ii)至少一种额外颜色的轴,其用于输出设备的颜色输出。 顶点生成单元通过选择(a)至少一个色域,在输出装置中使用组合输出的至少一个色域,在与设备有关的色空间中,生成构成色域表面的各子表面的顶点 至少一个额外颜色的三个基本颜色和一个对应于每个色域的基色,和(b)由输出装置使用四种基本颜色输出的色域。 色域表面生成单元生成由顶点构成的色域的表面上存在的表面点
