ABSTRACT:
An endoscopic apparatus has an objective optical system arranged in a rigid endoscope for forming an image, a first image re-forming optical system for re-forming a part of the image once formed through the objective optical system on an image pickup surface of a first CCD camera and a second image re-forming optical system which re-forms an image once formed through an objective optical system on an image pickup surface of a second CCD camera. A second monitor displays the image picked up by the second CCD camera added with a rectangular frame indicating size and amplitude of the area corresponding to the image picked up by the first CCD camera.
