摘要
ICC色彩管理是通过设备特性文件和色域映射实现的,设备的特性文件中记录了设备的颜色特性和介质、观察颜色的条件等信息,是色彩管理的要素之一。对不同再现意图色域的分析表明,由于在建立设备特性文件时目标设备未知,感知再现意图的色域并不能真实反映设备的色域,使感知再现意图的颜色转换不具有互逆性。使用PRMG(再现意图介质参考色域)可以规范感知的再现意图色域,有利于颜色转换的计算。对色域映射的分析表明,使用设备连接特性文件可以得到更好的颜色转换效果。
Color transformation between devices is based on the profiles and color gamut mapping in ICC color management system.All characteristics of the device are recorded in the profile,including color characteristics,media properties and viewing conditions,so that it is the key factor of CMS.The analysis to the color gamut of different rendering intent in the profiles shows that the gamut of A2B0 is not the real one of the device,because the destination device is unknown when it is constructed.This property makes the color transformation in perceptual intent not turn back.The use of PRMG(Perceptual intent Profile Reference Medium color Gamut) can improve the performance of color transformation in perceptual intent.The analysis also shows that the device link profile can make better color transformation results.
