Abstract
In the light source unitA, a switching filter sectionwhich can switch the RGB filter for normal-light observation and a filter for fluorescent observation on the optical path, is installed in front of the lamp, where if the fluorescent image mode is selected, the excitation light in a part of the blue wavelength band is supplied to the electronic endoscopeA, and the excitation light reflected by the subject side is shielded by the excitation light cut filterin front of the CCDso as to obtain the fluorescent image, and also the signal of the fluorescent image and the signals of the two reflected light images which are set in a predetermined wavelength band are passed through the image processing circuit, where a matrix circuit for appropriately allocating the color signals of the R, G and B channels is installed, and as a result, the images can be displayed on the monitorin pseudo-colors in hues which allow easy identification of a normal tissue and a pathologically affected tissue.
