ABSTRACT:
In a camera attached to the eyepiece section of an endoscope is arranged a photoelectric element for generating photoelectric signal corresponding to the brightness of light reflected from an object and transmitted through an image guide in the endoscope. The photoelectric signal of the photoelectric element is converted by a current-voltage converter/integrator circuit to an observation light control signal at the time of observation while to photographing light control signal at the time of photographing. The current-voltage converter/integrator circuit also generates sync signal in response to the release action. Each of the observation light control signal, sync signal and photographing light control signal is transmitted to a light supply unit through a signal transmission line. The signal transmitted is judged through the light supply unit to be observation light control signal, sync signal or photographing light control signal according to its polarity and level. The light control of an observation light source or photographing light source is achieved according to signal judged.
