Abstract

The endoscopic diagnosis system includes a white light source for emitting white light, a narrowband light source for emitting narrowband light having a given wavelength range of blue light, an image sensor receiving reflected light of the white light and the narrowband light emitted with a given emission ratio to illuminate a subject from the subject to acquire a narrowband light image, and an image processor for calculating an enhanced luminance signal where a blue image signal of the narrowband light image is enhanced, calculating a hemoglobin index representing blood level in a medium to deep layer of a mucous membrane from a green image signal and a red image signal of the narrowband light image, calculating an enhanced color difference signal enhancing red according to a value of the hemoglobin index, and producing an image signal of an endoscopic image for display from the enhanced luminance signal and the enhanced color difference signal.
