News editors obtained the following quote from the background information supplied by the inventors: "An advantage of time-sequential autostereoscopic systems as compared with space sequential autostereoscopic systems is that time-sequential autostereoscopic systems provide high resolution of 3D images irrespective of the number of perspective views used for producing the 3D images. Up to now the high quality and high resolution 3D images in 3D display apparatus have been achieved by using displays that allow collimating optical beams emanating therefrom. However, displays with pixels radiating as extended light sources and having wide directional diagrams (for example LCD) are generally unable to provide collimation of optical beams. Consequently, employing (utilizing) such pixel radiating displays in a time-sequential 3D display apparatus using known optical imaging system is problematic.
"The present invention provides a new optical imaging system that can be used in a time-sequential 3D display apparatus to produce high quality and high resolution multi view 3D images."
As a supplement to the background information on this patent application, VerticalNews correspondents also obtained the inventors' summary information for this patent application: "An object of the present invention is to provide an optical imaging system and a 3D display apparatus having substantially suppressed or eliminated superposition of different perspective views in each viewing zone by reducing radiating aperture of each pixel on the display pixel surface (thereby solving shortcomings associated with prior art optical imaging systems).
"In brief, the present invention is based on generating directional optical beams, transforming these optical beams and projecting the transformed optical beams in a field of view to form respective perspective views in each viewing zone in the field of view thereby producing a 3-dimensional (3D) image of an object or scene therein.
"The present invention may be embodied in an optical imaging system and a 3D display using the same system.
"In another aspect, the present invention is directed to optical imaging systems and related 3D displays based on using collimated optical beams emanating from pixels located on a display pixel surface.
"As way of background, optical beams emanating from some displays (for example, LCD) have pixels with wide directional diagrams (almost 180 deg.) that impose strict limitations on the number of perspective views or even prevent the formation of 3D images. The present invention solves this problem. The present invention may be implemented by using an array of selecting light guide elements together with a lens array of converging micro-lenses in an optical imaging system and a related 3D display apparatus as disclosed herein.
"The present invention builds upon the 3D display and optical imaging systems disclosed in our prior U.S. application Ser. Nos. 11/364,692 and 11/769,672, both of which applications are incorporated herein by reference in their entireties for all purposes.
"These and other aspects of the present invention will become more evident upon reference to the following detailed description and attached drawings. It is to be understood, however, that various changes, alterations, and substitutions may be made to the specific embodiments disclosed herein without departing from their essential spirit and scope.
