System for viewing three dimensional images
First Claim
1. A viewing system for viewing images displayed in two dimensions on a viewing screen with a three-dimensional effect, comprising:
- a pair of polarizing filters disposed between the viewing screen and a viewer for polarizing on different axes light from a respective pair of slightly different images of a common subject displayed on the viewing screen; and
a pair of eyeglasses having a pair of lens openings for respective placement in front of the right and left eyes of the viewer, a pair of polarizing lenses respectively covering the lens openings and oriented generally upon axes conforming respectively with said polarizing filters whereby the viewer'"'"'s right and left eyes will observe different ones of the pair of images, image shifting and magnification lens means respectively covering the lens openings, and means for adjusting said image shifting lens means for displacing the observed images into a viewer-perceived superimposed relation forming a composite image having a three-dimensional appearance.

Abstract
A viewing system is provided for viewing images with a three-dimensional effect, wherein the system is particularly adapted for viewing television images in full color. The viewing system comprises a filter mat having two juxtaposed polarizing filters for placement over a television viewing screen or other rear surface projection device in substantial registry with two similarly juxtaposed and slightly different images of a common scene or subject. The polarizing filters are oriented on different axes to polarize the light from the two images on different axes. The viewer observes these polarized images through eyeglasses having lens openings covered by polarizing lenses oriented with respect to the polarizing filters of the filter mat such that the two images are respectively observed by the viewer'"'"'s right and left eyes. The eyeglass lens openings are further covered by movable image shifting lenses supported for simultaneous adjustment to merge the observed images into superimposed relation thereby providing a highly realistic three-dimensional effect. Magnification of the merged images is also provided in preferred forms of the invention.

12. A viewing system for viewing images displayed in juxtaposed relation on a television viewing screen with a three-dimensional effect, comprising:
-
a filter mat for placement over the television screen, said mat having a pair of transparent polarizing filters in generally juxtaposed relation for general registry with the images on the screen and being oriented for polarizing light from the two images on different axes; and a pair of eyeglasses having a pair of lens openings for respective placement in front of the right and left eyes of a viewer, a pair of polarizing lenses respectively covering the lens openings and oriented generally upon axes conforming respectively with said polarizing filters whereby the viewer'"'"'s right and left eyes will observe different ones of the pair of images, image shifting lens and magnification lens means respectively covering the lens openings, and means for adjusting said image shifting lens means for displacing the observed images into a viewer-perceived superimposed relation forming a composite image having a three-dimensional appearance.

13. A pair of eyeglasses for viewing two-dimensional images with a three-dimensional effect, comprising:
-
a front frame half having a front wall with a pair of laterally spaced lens openings formed therein and a generally peripheral flange projecting rearwardly from said front wall; a rear frame half having a rear wall with a pair of lens openings formed therein with a lateral spacing generally corresponding with the lateral spacing between the lens openings of said front frame half, and a generally peripheral flange projecting forwardly from said rear wall; a pair of polarizing lenses secured against rotation in positions respectively covering the lens openings of said front frame half, said polarizing lenses being oriented for polarizing light passing therethrough on different axes; a pair of prismatic lenses each supported within a respective, generally ring-shaped lens case; wall means projecting forwardly from said rear wall of said rear frame half defining a pair of arcuate support walls bounding each of said rear frame half lens openings in slightly radially spaced relation thereto, said lens cases carrying said prismatic lenses being respectively rotatably supported within said pairs of support walls, said wall means further defining a relatively narrow track extending generally between a lower region of one of said rear frame half lens openings and an upper region of the other of said rear frame half lens openings; a longitudinally stiff adjustment band extending through said track and having opposite ends secured to said lens cases; and a control rod secured to one of said lens cases and extending outwardly therefrom through a slot defined cooperatively by said front and rear frame halves, said control rod being manually movable to rotate said prismatic lenses simultaneously in opposite rotational directions.

14. A pair of eyeglasses for viewing two-dimensional images with a three-dimensional effect, comprising:
-
a frame assembly including a rear frame member and a front frame member movably supported on said rear frame member, said frame members each having a pair of lens openings formed therein, and means for retaining said frame assembly on the head of a viewer; a pair of polarizing lenses respectively covering the lens openings of said rear frame member, said polarizing lenses being oriented for polarizing light passing therethrough on different axes; and a pair of rear magnification lenses respectively covering the lens openings of said rear frame member and a pair of front magnification lenses respectively covering the lens openings of said front frame member, said front and rear magnification lenses cooperating with each other for magnifying images observed by the viewer therethrough; said front frame member being movable relative to said rear frame member to displace said front magnification lenses relative to said rear magnification lenses to shift images viewed therethrough by the viewer. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)

22. A pair of eyeglasses for viewing two-dimensional images with a three-dimensional effect, comprising:
-
a frame assembly having a pair of lens openings; polarizing means for polarizing light images passing through the lens opening on different axes; means for shifting the perceived position of the images observed through the lens openings; and means for magnifying the images passing through the lens openings.
