The main aim of this study is to develop a capturing system which can record the object's visual spectral quick and accurately by one snap. The general multi-spectral imaging systems must sequentially capture five or seven images for recovering the visible spectral. Such systems are complicated and stationary. In this paper, we present the development of a portable multi-spectral imaging system that consists of a multi-image 5X prism, a set of five color filters and a digital still camera. Additionally, the algorithms of image segmentation will be disclosed to solve the problem of image overlaps by multi-image prism. Next the outputs of camera and spectral function are represented by spectral characterization. An experiment was performed to test whether this technique could be used with digital capture of real objects. Finally, results revealed that the color error were reasonable small.
