Portable viewing apparatus
First Claim
1. Portable viewing apparatus for use by a viewer in an enhanced visual effect when viewing displayed images that are horizontally compressed relative to their normal proportions, providing, the apparatus comprising:
- optical path means defining left and right optical paths for transmitting the displayed image to a viewer'"'"'s left and right eyes, wherein the optical path means includes convergence means for selectively adjusting the convergence of the left and right optical paths toward the viewer'"'"'s respective left and right eyes, and wherein the defined optical paths are free of any optical occluders, filters, or polarizers and are free of any wedge lenses for modifying the vertical positions of the images;
disanamorphic lens means located in the left and right optical paths, for horizontally expanding the images being transmitted along the optical paths to the viewer'"'"'s left and right eyes such that the images are restored to their normal two-dimensional proportions; and
means for carrying the optical path means and disanamorphic lens means in predetermined positions on the viewer'"'"'s head, to allow the viewer to move independently relative to the displayed images and to selectively operate the means for adjusting convergence as the need arises;
wherein the viewer is enabled to perceive the displayed images in their normal two-dimensional proportions, with an enhanced visual effect.

Abstract
A viewing apparatus for use in providing either a three-dimensional image when used to view a side-by-side display on a conventional video screen of related left and right images that are each horizontally compressed, or alternatively for use in providing a wide-angle image when used to view a single horizontally compressed image displayed on a conventional video screen. In providing the three-dimensional image, the apparatus transmits the displayed left image to the viewer'"'"'s left eye and the displayed right image to the viewer'"'"'s right eye, while horizontally expanding the compressed images and returning them to their original, natural porportions. The displayed side-by-side images both extend along the screen'"'"'s entire vertical length, such that a three-dimensional effect is provided having the same two-dimensional proportions as the conventional video screen. In providing the wide-angle image, the apparatus transmits the single horizontally-compressed image to the viewer'"'"'s two eyes, while horizontally expanding the image to return it to its original, natural porportions.

8. Portable viewing apparatus for providing expanded images for a viewer that are based on a display on a conventional television screen of horizontally compressed images, the apparatus comprising:
-
optical path means defining left and right optical paths for transmitting the displayed images to a viewer'"'"'s respective left and right eyes, wherein the defined optical paths are free of any optical occluders, filters, or polarizers and are free of any wedge lenses for modifying the vertical positions of the images, wherein the optical path means include means for selectively adjusting the convergence of the left and right optical paths toward the viewer'"'"'s respective left and right eyes, whereby the apparatus is usable at a range of distances from the screen, and means for selectively adjusting the interocular spacing of the left and right optical paths at the viewer'"'"'s left and right eyes, whereby the apparatus is adapted for use by multiple viewers; disanamorphic lens means including separate lenses located in the left and right optical paths, for horizontally expanding the respective left and right images being transmitted along the optical paths to the viewer'"'"'s respective left and right eyes such that the viewed images are restored to their normal two-dimensional proportions; and a frame for carrying the optical path means and disanamorphic lens means in predetermined positions on the viewer'"'"'s head, to allow the viewer to move independently relative to the displayed images; wherein the viewer is enabled to perceive an image in its normal two-dimensional proportions regardless of the viewer'"'"'s range from, or position relative to, the screen. - View Dependent Claims (9, 10, 11)
