<p>An endoscopic photographing apparatus has an endoscope (11), a camera (13) mounted to an eyepiece section (12) of this endoscope (11), and a light supply unit (17) to which is connected a connector section (16) of the endoscope (11). The camera (13) is provided with a photosensitive element (29) for generating a photoelectric signal corresponding to the intensity of light which enters it via an image guide (22) of the endoscope (11), an exposure calculating circuit (30, 36, 37) for calculating the exposure from the photoelectric signal from this photosensitive element (29) to generate a quenching signal based upon the calculated exposure, and a buffer circuit (38) for outputting a signal of high level in response to the quenching signal from this exposure calculating circuit (30, 36, 37). When the signal of high level from this buffer circuit (38) is input to the exposure calculating circuit (60) of the light supply unit (17), the exposure calculating circuit immediately outputs a signal for terminating the light flash of the light source (67).</p> |
