Abstract
An endoscopic photographing apparatus has a TV camera with a CCD image sensor which is mounted on an eyepiece section of an endoscope, a light flash source for supplying a light flash as photographing light to the endoscope, and an observation light source for supplying observation light. The light flash source is turned on in synchronism with a release signal and a transfer gate pulse for the video signal, at the time of still image photographing. The photographic field of view of the TV camera is darkened for at least one-field scanning period, before the light flash source is turned on.
