A stereo one-shot multi-band camera system for accurate color reproduction

In the digital archiving for cultural heritage preservation, in the medical field, and in some industrial fields, high-fidelity reproduction of color, gloss, texture, and shape are very important. Multiband or full-spectrum imaging technology is a solution for accurate color reproduction. Although several types of multi band camera systems have been developed [Yamaguchi 2000, Tominaga 2000, Helling 2004, Hashimoto 2008], all of them are multi-shot systems and they cannot take images of moving objects. Ohsawa et al. [2004] have developed a six-band HDTV camera system. However, the system requires very expensive customized equipment. In order to make multiband technology pervasive, equipment costs must be reduced and the systems have to be able to take images of moving objects. To meet these requirements, we developed a novel multiband image capturing system that combines multiband and stereo imaging techniques. This system can acquire both spectral color information and depth information at the same time. In this paper, we focus on the generation of six-band images from a pair of stereo image.
