Patent number: 9753294Abstract: Moving pictures, as exemplified by ordinary television programming, are viewed stereoscopically when viewed using a special eyewear apparatus which includes a prismatic lens construction. The three dimensional effect is produced by the design of the eyewear to redirect the visual tracking of one or both eyes away from the normal convergent angle used when viewing display screens to a wider angle, which is normally associated with viewing objects at a greater distance that the display screen. This causes the eyes to perceive two distinct views of the single picture on the screen, which are interpreted by the viewer's brain, not as two laterally displaced pictures, but as a single picture with elements of depth, or a 3D picture.Type: GrantFiled: February 9, 2015Date of Patent: September 5, 2017Inventor: Leslie C.

A method of producing a displayed image using a passive display illuminated by a light source is characterized in controlling the light source to obtain a displayed image with a desired amount of information, gray scale and/or color characteristics. A method of reducing power consumption by a display system in which a light modulating display modulates incident light from a light source to provide images is characterized in controlling power provided to the light source to reduce output thereof for relatively dark images.Type: ApplicationFiled: October 31, 2007Publication date: May 8, 2008Inventor: James Fergason
