Abstract
An electronic endoscope apparatus has an arrangement that its discrimination circuit discriminates the type or the operational state of the light source in accordance with a discrimination signal transmitted from a discrimination signal generator, and in accordance with the result of the discrimination, the processing operation to be performed by its video signal processing circuit is changed over to correspond to the difference in the type or the operational state of the light source. The video signal processing circuit performs a proper signal processing operation to correspond to the difference in the type of the light source to prevent deterioration in the image quality. The electronic endoscope apparatus is structured so that a different type light source can be adaptably connected to it.
