Patent

CA 2151464

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 (2, 6), 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 (10, 12) 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.
