PURPOSE:To observe the successive movement by using one set of a camera by disposing two stereoscopic optical paths in an optical system and providing a shutter for alternately transmitting and shielding the light flux of respective optical paths. CONSTITUTION:On the two stereoscopic observation optical paths at the rear part of an objective lens 1, Galileo variable power optical systems 2a, 2b, liquid crystal or mechanical shutters 3a, 3b are disposed, and further, an imaging lens 4 and an image pickup element 5 are commonly disposed on both the optical paths. The shutters 3a, 3b repeat an opening and a closing alternately synchronously with the frame of the image pickup element 5 by a driving circuit 5 not shown. Light passing through two optical axes 0a, 0b by a prism operation in the peripheral part of the objective lens 1 becomes to the light flux seen by both eyes of a human being. The imaging lens 4 deflects the two optical axes 0a, 0b on the image pickup element 5 according to the prism effect in the periphery and forms an image, reversely to the objective lens 1. |
