摘要： A light source unit, which is connected to a control unit and an endoscope, radiates a pre-determined light quantity of white light based on a signal from the control unit. The light source unit includes a lamp as a white light source, an infrared cut filter, a light quantity limiting filter, being inserted/removed on an optical path, for limiting light quantity in a pre-determined wavelength region of white light, a filter insertion/removal driving unit for inserting/removing the light quantity limiting filter on an optical path, and a condensing lens for outputting white light. For example, when a transmission rate of a blue band is 100%, the light quantity limiting filter limits transmission rates of other bands to 50%. This improves S/N in discrete spectral image generation with illumination light in a visible light region.

摘要： A white light from a lamp passes through R, G, and B filters of a rotating filter and turns into broadband R, G, and B frame sequential illumination lights. The lights are applied to a living mucous membrane in a body cavity through an electronic endoscope, and sequential image pickup is performed by a CCD. Output signals from the CCD are sequentially switched by a selector in a filter circuit. An R signal, a G signal, and a B signal pass through the filter circuit 36 through no medium, a BPF, and an HPF, respectively, and are separated into signal components corresponding to spatial frequency components of living mucous membrane structures. The separation leads to generation of image signals of an image which allows easy identification of the living mucous membrane structures.
