Abstract

PURPOSE:To observe the image of an object to be observed in different wavelength regions, by mounting a change-over means, which changes over the first wavelength region separating means and the second wavelength region separating means, to an electronic endoscopic apparatus. CONSTITUTION:When the image of an object to be observed of a visible light region is observed, an infrared ray cutting filter 32 is interposed in an illumination light path by a change-over circuit 45 and a rotary filter 34 is retracted from the illumination light source. The light transmitting through the filter 32 of a lamp 31 is incident to an iris 35 and condensed by a lens 36 to be incident to a light guide 34. This illumination light is allowed to irradiate the object 25 to be observed and the image of the object to be observed in the visible light region is displayed on a color monitor 7. When the image of the object to be observed in an infrared region is observed, the infrared ray cutting filter 32 is retracted from the illumination light source by the change-over circuit 45 and the rotary filter 34 is interposed in the illumination light path. The image of the object to be observed in the infrared region is displayed on the monitor 7 by a dummy color.
