Abstract:
An electronic stereoscopic system for sending different images towards a viewer's left eye and right eve to generate, for the viewer, a three-dimensional view of an image, said electronic stereoscopic system comprising:image generating means for generating a successive series of frames of images;directing means, coupled to the image generating means comprising a liquid-crystal screen for directing one or more of the successive series of frames of images towards a viewer's left eye and right eye independently, at a rate sufficient so that the viewer's eyes do not perceive discontinuities due to persistence of vision, so as to generate a stereoscopic image; andan image synchronization block, coupled to said directing means comprising the liquid-crystal screen and said image generating means, for synchronizing direction of the one or more of the successive series of frames of images with generation of the one or more of the successive series of frames of images,wherein the image generating means comprises a television which emits, as alternate groups each of at least one frame, stereographic images,wherein said liquid-crystal screen is placed in front of the television;wherein the synchronization block is coupled to the television by an optical sensor which determines when the end of a frame occurs.
