摘要

PPROBLEM TO BE SOLVED: To provide a color gamut mapping method and a color gamut mapping device for mapping a color signal to the color gamut of a target device for reproducing approximately original hue of the color signal. PSOLUTION: A hue angle correction data calculating part 1 is designed to calculate a hue angle correction data after calculating a group of a non-corrected device independent color signal and a corrected device independent color signal on a plurality of half planes. The non-corrected device independent color signal corresponds to the color signal on a half plane including a achromatic axis in a standard device color space. The corrected device independent color signal has a hue angle of the standard device independent color signal having the highest color saturation on the same half plane as the non-corrected device independent color signal, and the brightness and the color saturation of the non-corrected device independent color signal. The color gamut mapping process is performed by a color gamut mapping unit 3 after being performed a hue angle correction process in relation to the color signal on the space of the device independent color signal based on the hue angle correction data by a hue angle correcting unit 2, then an inverse correction of the hue angle correction is performed by a hue angle inverse correcting unit 4.

要解决的问题：提供一种色域映射方法和色域映射设备，用于将颜色信号映射到目标设备的色域，以再现颜色信号的近似原始色调。

解决方案：色相角校正数据计算部分1设计为在多个半平面上计算一组非校正后的与设备无关的颜色信号和校正后的与设备无关的颜色信号之后，计算出色相角度校正数据。未校正的设备无关颜色信号对应于标准设备颜色空间中包括消色差轴的半平面上的颜色信号。校正后的设备独立色信号具有与非校正后的设备无关色信号在同一半平面上具有最高色彩饱和度的标准设备无关的色信号的色相角，以及校正后的设备的亮度和色饱和度。独立的颜色信号。在色相映射单元3基于色相角校正单元基于色相角校正数据对设备独立色信号的空间上的色信号执行色相角校正处理之后，由色域映射单元3执行色域映射处理。参照图2，然后由色相角逆校正单元4执行色相角校正的逆校正。
