ABSTRACT:
A stereosopic (3-D) converter assembly usable in conjunction with a standard 2-D closed circuit TV system in which a video camcorder (video camera+VCR) functions to record moving images of a scene seen through the monocular lens of the video camera and to play back the recording to yield a composite video signal that is fed to a TV monitor on whose screen the images are exhibited. The assembly is constituted by a shuttered binocular optical attachment placed in front of the camera lens, a binocular electro-optical viewer through which the screen of the monitor is seen by an observer, and a controller unit for activating either the attachment or the viewer. In the recording mode of the assembly, the controller unit in response to vertical sync pulses derived from the composite video signal yielded by the camera activates the optical attachment alternately to present to the camera lens left and right eye images of the scene, this action resulting in a 3-D recording. In the playback mode in which the composite video signal from the VCR is fed to the TV monitor, the controller unit in response to vertical sync pulses derived from this composite video signal then activates the viewer alternately to present to the left and right eyes of the observer, the corresponding screen images, thereby affording a stereoscopic presentation.
