摘要：

For a reliable diagnosis through visual telecommunication systems, it is very important to reproduce patient images with correct color. Natural color television system previously proposed is capable of reproducing the original color of the objects using multispectral images, even when the illumination environment for observing images is different from the illumination used for recording. In this paper, to render this system practical for telemedicine system, we reduce the number of color bands of multispectral camera by utilizing the principal components of spectral reflectances in human skin class. In addition, we investigate a simple method, using color charts, to obtain the recording information of both illumination and camera. As a color chart selection criterion, it becomes clear that principal components for human skin class need to be described by the linear combination of spectral reflectances of color charts. Principal components for human skin class are obtained through measurements and analysis of 484 human skin spectral reflectances. In the experiment, natural color reproduction for human skin is realized from limited number of color bands using color charts for acquiring the recording information instead of spectral measurement devices.
