    • An image processing method is used to converting a color within a first color reproduction range that is a device-independent color space into a color within a second color reproduction range that is a color reproduction range of an output device. The image processing method includes defining, within the first color reproduction range, a third color reproduction range of a color that is estimated to be input; defining, within the second color reproduction range, a fourth color reproduction range that is smaller than the second color reproduction range; and, in performing the color conversion, compressing a color within the third color reproduction range into a color within the fourth color reproduction range and compressing a color within the first color reproduction range and outside the third color reproduction range into a color within the second color reproduction range and outside the fourth color reproduction range.
    • 图像处理方法用于将作为与设备无关的色彩空间的第一颜色再现范围内的颜色转换成作为输出设备的颜色再现范围的第二颜色再现范围内的颜色。 图像处理方法包括在第一颜色再现范围内定义被估计输入的颜色的第三颜色再现范围; 在所述第二颜色再现范围内限定小于所述第二颜色再现范围的第四颜色再现范围; 并且在执行颜色转换时,将第三颜色再现范围内的颜色压缩成第四颜色再现范围内的颜色,并将第一颜色再现范围内的颜色和第三颜色再现范围外的颜色压缩成第二颜色内的颜色 再现范围和第四色彩再现范围之外。
