ABSTRACT:
An endoscope system for examining organic tissue that uses a light source to generate persistent fluorescence (that is, fluorescence that remains after the generating source is turned off or removed) in organic tissue. Two shutter mechanisms are controlled such that only the persistent fluorescence is allowed to reach an image receiving device, such as a CCD area sensor. The two shutters are controlled such that the CCD area sensor is exposed to the persistent fluorescence either once or a plurality of times before the image data is output. If the CCD is only exposed once, a number of CCD outputs are accumulated in a picture memory. The image generated from either the CCD output (for the plurality of exposures case) or the picture memory (for the single exposure case) is displayed on a display device.
