PURPOSE: To easily distinguish the rugged part of a lesion from other parts in the observation of the wall of the stomach, etc., by employing such constitution that a video for stereoscopic vision is displayed based on every piece of video information from a first video input part and a second video input part arranged by separating from each other.
CONSTITUTION: A flexible cable 2 inserted from the mouth to the stomach of a patient 1 is composed in such a way that its tip on a stomach side is formed as a video input part 3, and it comprises the first video input part 3A and the second video input part 3B separated from each other. Light outputted via each optical fiber in the cable 2 is inputted to an optic/electric signal converter 7, and converted to an electrical signal (video signal) in accordance with the intensity of the light, and inputted to a display device 8. The video from the first video input part 3A and the one from the second video input part 3B are recognized by both eyes 13A, 13B of an observer 12 at nearly same time via a lenticular lens on a display surface 8A. In this way, the observer 12 obtains the stereoscopic vision of an image-picked up video via the display device 8.
