A first video signal is produced in a video signal processing circuit within a video processor by an imaging device provided in an endoscope, is put into a switching circuit, has the tone and the like corrected by a picture image correcting circuit within an outer peripheral apparatus provided outside the video processor and is converted to a second video signal electrically different from the first video signal. The second video signal is recorded and is displayed in a color monitor through a switching circuit. In case the outer peripheral apparatus is abnormal and a normal picture image is not displayed in the color monitor, by the operation of a forcibly set switch, the first video signal produced in the video signal processing circuit within the video processor will be quickly displayed in the color monitor without being passed through the outer peripheral apparatus.
