Obtaining and reproduction of accurate color images based on human perception

We have developed high definition color imaging systems for digital artworks. The system is consisted of multiband camera, personal computer and projection type monitor. The multiband camera is composed by five band filters and single chip CCD camera with 2048 by 2048 pixels. On the basis of principal component analysis and Wiener estimation method, the reflectance spectra of each pixel of the object were estimated using five band images taken by CCD camera. Images of paintings are reproduced onto both the projection type monitor and CRT under the consideration of color appearance. In this paper, method to estimate of reflectance spectra of paintings from five band images is described, and the color reproduction of paintings based on the color appearance models is also discussed.
