Abstract
An endoscopic photographing apparatus has an endoscope, a camera mounted to an eyepiece section of this endoscope, and a light supply unit to which is connected a connector section of the endoscope. The camera is provided with a photosensitive element for generating a photoelectric signal corresponding to the intensity of light which enters it via an image guide of the endoscope, an exposure calculating circuit for calculating the exposure from the photoelectric signal from this photosensitive element to generate a quenching signal based upon the calculated exposure, and a buffer circuit for outputting a signal of high level in response to the quenching signal from this exposure calculating circuit. When the signal of high level from this buffer circuit is input to the exposure calculating circuit of the light supply unit, the exposure calculating circuit immediately outputs a signal for terminating the light flash of the light source.
