Designing study of multi-spectral imaging system based on two CCD

摘要

The color reproduction technique, based on the multi-spectral imaging and spectrum estimation, has become the front of the color science & engineering field since the nineties of last century. When the image is reproduced, both high resolution and reproduction precision are desired. The image recorded by the traditional photography bases on metamerism. Although it can provide the image with high resolution, due to metameric phenomenon, the color reproduction can not be accurate. Thereby, a method for color reproduction is needed. Multi-spectral imaging technique, which is a system of multi-spectral image collection containing CCD, filters etc, realizes spectral reproduction of the object by the algorithm of spectral estimation.
