We have developed a new electronic endoscopes to record and reproduce the arbitrary spectral images of the mucous membrane such as the gullet, colon and stomach. The reflectance spectra of those membranes can be estimated by the Wiener estimation method based on the principal component analysis of measured reflectance spectra of membrane by the endoscope spectrophotometer. In this paper, we show that the endoscopes are greatly significant to diagnose the various kinds of diseases in comparison with the conventional electronic endoscopes used R, G and B color information.
