色差数据的可视化分级及其应用

Visualization and grading of color difference data and its application

针对色彩管理的难点,利用色差数据的灵活性,结合RGB数据的可视化效果,在RGB系统中构建色差分级参考样品系统,实现实物色卡不能实现的色差分级自由度和样品丰富性。再将标准样和批次样的色差管理放入该分级系统中,对标准样和批次样的RGB显示准确性进行目测管理,在色差数字化管理的初始阶段引入目测校正,结合数字化色差管理的优点和目测管理的可靠性,提高了色差数字化管理的可靠性下限,带来了色差数字化管理的新思路。

In view of the difficulty of color management,a color difference grading reference sample sys⁃tem was constructed in RGB system by using the flexibility of color difference data and the visualization effect of RGB data,so as to achieve the freedom of color difference grading and sample richness that could not be achieved by physical color cards.Then,the color difference management of standard samples and batch sam⁃ples was put into the grading system.By visually managing the RGB display accuracy of standard samples and batch samples,visual correction was introduced at the beginning of color difference digital management.Com⁃bining the advantages of digital color difference management and the reliability of visual management,the low⁃er limit of reliability of color difference digital management was improved,bringing new ideas for color differ⁃ence digital management.
