光谱颜色管理系统关键技术综述

Key Technologies Review of the Spectral Color Management System

随着数字信息技术的全面、系统、纵深化发展,实际应用中对彩色图像跨媒体复现的颜色精度要求越来越高。基于光谱的颜色管理系统可以有效解决色度颜色管理系统中存在的同色异谱问题。本研究在分析光谱颜色管理系统基本框架的基础上,总结了光谱颜色管理系统中多光谱图像采集、光谱重构、光谱设备无关连接空间定义、光谱色域描述、光谱色域映射算法和光谱分色等关键技术的研究现状,并对各个技术环节中亟待解决的关键问题进行了归纳分析。

The accuracy requirement of color image cross - media reproduction is increasing in practice with the comprehensive, systematic and in - depth development of digital information technologies.The spectral color management system could well resolve the metamerism problems in the traditionally colorimetric management system.Firstly,the basic framework of the spectral color management system was constructed.Secondly,the study status of the key technologies including multispectral image acquisition,spectrum reconstruction,the definition of interim connection space,spectral gamut description, spectral gamut mapping algorithm and spectral color separation were reviewed.Finally,the problems to be immediately resolved in the spectral color management system were summarized and analyzed.
