Estimating the term…
Stereoscopic images are presented by alternately displaying corresponding left eye and right eye images in succession, substantially extinguishing transmission of light from the left eye images to the right eye of a viewer and from the right eye images to the left eye of the viewer, for example by the use of polarizing filters, and alternately and in synchronism with the alternate display of images, scattering unextinguished light from the left eye images that leaks through to the viewer's right eye and from the right eye images that leaks through to the viewer's left eye. In a preferred embodiment, scattering is achieved by using a liquid crystal scattering shutter that is electrically triggered in synchronism with the display of images. The shutter disperses the unextinguished light that leaks through the system so that no image information is perceived and the light appears merely as a slight increase in background illumination.
A method of presenting stereoscopic images which comprises the steps of:
An apparatus for presenting stereoscopic images, which comprises:
Eyeglasses for viewing stereoscopic images comprising corresponding left-eye and right-eye images displayed in succession, the eyeglasses having respective left-eye and right-eye lenses and including means for substantially extinguishing transmission of light from displayed left-eye images to the right eye of a viewer and from displayed right-eye images to the left eye of the viewer, and means for alternately and in synchronism with said alternate display of images, scattering unextinguished light from the left-eye images that leaks through the extinguishing means to the viewer's right eye and from the right-eye images that leaks through said extinguishing means to the viewer's left eye, each of said lenses including one of blocking shutter means and filter means for providing said substantial extinction of light transmission, and an electro-optic scattering shutter which is actuable in synchronism with said alternate display of images, between a transmissive state and scattering state.
