Abstract

Multispectral color image scanning and the transport of relevant spectral information up to output devices offer essential advantages compared to conventional three channel color reproduction. This is particularly true in open image communication systems which have to consider many different color reproduction technologies. The first part of the paper covers fundamental problems of three channel color image scanning. Afterwards, the basic ideas of a multispectral reproduction technology are presented to solve the problems. The multispectral scanner as a main part of the system is addressed in the next chapter. A major problem of multispectral technology is the encoding of the large amount of spectral data delivered by the scanner. A second important point with respect to the application of multispectral technology is compatibility with existing color systems using tristimulus color values. The paper present concepts for compatible and efficient spectral data encoding and discusses aspects of optimization strategies. The state of the art of multispectral technology and an outlook are given finally.
