Abstract

The color reproduction accuracy of a multispectral video system was visually evaluated by expert dermatologists to investigate the feasibility of the system in telemedicine applications. The erythema produced by a skin prick test was used as a substitution of real skin lesion, and the dermatologists performed a color matching experiment, in which the color chips were compared with the reproduced images and the real skins. As a result, the mutisperctral video system, consisting of 6-band HDTV camera, 6-primary display and spectrum-based color reproduction, decreased the perceptual color difference between the reproduced image and the real object, as compared with a conventional 3-band HDTV system. It was also shown that the oversights of skin lesions could be reduced in 6-band video reproduction. Through the experiments including multispectral video transmission between the remote hospitals in addition to above skin color matching, dermatologists rated that the natural color reproduction realized by multispectral video is almost satisfactory for the diagnosis of skin disorders.
