中文摘要： 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。传统基于同色异谱的颜色表征及色度复现方法存在颜色信息丢失及彩色图像跨媒体复现精度受照明观察环境影响等问题，难以有效满足各种应用要求。本项目对能够完整描述及复现颜色信息的光谱颜色管理系统中的关键理论和方法进行研究，实现彩色图像跨媒体准确的光谱复现。首先对色度复现系统中同色异谱的成因及影响进行分析，在此基础上定义具有明确颜色意义且实用价值较高的光谱连接空间，然后在光谱连接空间中实现设备光谱色域描述、色域映射算法设计以及多基色打印机光谱分色，最后给出多光谱图像数字典藏及跨媒体复现应用实例。研究成果可以广泛用于文化艺术品的数字典藏及复制、数字出版及发行、远程医疗、电子商务等众多对彩色图像跨媒体复现精度有较高需求的应用领域，另外对多基色设备开发过程中的基色选取、分色算法设计等也有较高的理论参考价值。

英文摘要： The requirement of color image accurately cross-media reproduction is increasing in practice with the comprehensive, systematic and in-depth development of digital information technologies. The traditionally colorimetric representing and reproduction method based on metamerism could not meet various application requirements as the problems of color information losses and reproduction accuracy affected by lighting and observing environments. The key theories and methods of the spectral color management system, which could exactly represent and reproduce the color information, would be studied to implement the cross-media spectral reproduction of color images. Firstly, the spectral interim connection space with definitively colorimetric meanings and high practical values would be defined based on the analyzed causes and effects of the metamerism in the colorimetric reproduction system, and then the spectral gamut description, spectral gamut mapping algorithm, spectral color separation of the multicolorant printer would be implemented in the defined spectral interim connection space. Finally, the application examples of the digital conservation and cross-media reproduction of multispectral images would be implemented. The study results could be widely used in various fields with high cross-media reproduction accura
