Electronic endoscope apparatus capable of observing laser-illuminated biological body portion

摘要: To prevent a halation phenomenon from forming on an endoscopic image of laser-illuminated cavity biological body under medical examination, electronic endoscope apparatus (100) comprises scope unit (10) and a main (20:30) coupled to the scope (10). The includes: laser mirror (50) upon which light (2) reflected from body examination is incident, for reflecting first component (2A) having wavelength incident also passing therethrough second (2B) visible wavelength other than wavelength; image sensor (12A) receiving first (50); (12B) directly the passing through mirror produce visible signal (12VS); and, ND (neutral density) filter (8) positioned light-receiving surface (12A), for lowering brightness having wavelength, thereby producing laser (12LS) (12A). processes both (12LS:12VS) display without any phenomenon.
