Abstract

An image display system provides a viewer with an experience of three dimensional images by presenting a composite image source. The system includes first and second image sources, a beamcombiner, a lens and a reflective element. The reflective elements reflects the image of the second image source to the beamcombiner. The first and second image sources, the beamcombiner, and the single lens present a foreground image and a background image, with the background image presented at a greater distance from the viewer than the foreground image. The viewer perceives the foreground image and the background image as part of a scene having depth.

Claims

1. A method for displaying a three-dimensional scene to a viewer, said method comprising:

simultaneously presenting to both eyes of a viewer a first image that is generally planar;

simultaneously presenting to both eyes of a viewer a second image that is generally planar and is co-aligned with said first image along an axis that is in the general direction of the viewer but at a perceptibly different distance from the viewer than said first image;

wherein the one of said images that is at a distance closer to said viewer depicts objects in the foreground of said three-dimensional scene and the other of said images depicts objects in the background of said scene, and wherein said first image and said second image are presented alternatingly to a viewer with a cycle that is within the time frame of persistence of vision, whereby the viewer observing said images perceives the depicted objects as part of a scene having real depth wherein at least one rotating member is utilized to rotate optical elements so that said viewer is presented with said first and second images at different distances from the viewer.

2. A method for displaying a three-dimensional scene to a viewer, said method comprising:

simultaneously presenting to both eyes of a viewer a first image that is generally planar;

simultaneously presenting to both eyes of a viewer a second image that is generally planar and is co-aligned with said first image along an axis that is in the general direction of the viewer but at a perceptibly different distance from the viewer than said first image;

wherein the one of said images that is at a distance closer to said viewer depicts objects in the foreground of said three-dimensional scene and the other of said images depicts objects in the background of said scene, wherein said first image and said second image are each presented from a single source, and wherein at least one of said images is a real image or virtual image presented by a single lens interposed between the single source and the viewer, whereby the viewer observing said images perceives the depicted objects as part of a scene having real depth.

3. The method of claim 2, wherein the single source is a television screen and said first image and said second image are each derived from a portion of the television screen.

4. A method for displaying a three-dimensional scene to a viewer, said method comprising:

simultaneously presenting to both eyes of a viewer a first image that is generally planar;

simultaneously presenting to both eyes of a viewer a second image that is generally planar and is co-aligned with said first image along an axis that is in the general direction of the viewer but at a perceptibly different distance from the viewer than said first image;

wherein the one of said images that is at a distance closer to said viewer depicts objects in the foreground of said three-dimensional scene and the other of said images depicts objects in the background of said scene, and wherein said first and second images are real images of first and second image sources, at least one of said real images being presented by a single lens interposed between the first image source and the viewer, whereby the viewer observing said images perceives the depicted objects as part of a scene having real depth.

5. A method for displaying a three-dimensional scene to a viewer, said method comprising:

simultaneously presenting to both eyes of a viewer a first image that is generally planar;

simultaneously presenting to both eyes of a viewer a second image that is generally planar and is co-aligned with said first image along an axis that is in the general direction of the viewer but at a perceptibly different distance from the viewer than said first image;

wherein the one of said images that is at a distance closer to said viewer depicts objects in the foreground of said three-dimensional scene and the other of said images depicts objects in the background of said scene, and wherein said first and second images are virtual images of first and second image sources, whereby the viewer observing said images perceives the depicted objects as part of a scene having real depth.

6. A method for displaying a three-dimensional scene to a viewer, said method comprising:

simultaneously presenting to both eyes of a viewer a first image that is generally planar;

simultaneously presenting to both eyes of a viewer a second image that is generally planar and is co-aligned with said first image along an axis that is in the general direction of the viewer but at a perceptibly different distance from the viewer than said first image;

wherein the one of said images that is at a distance closer to said viewer depicts objects in the foreground of said three-dimensional scene and the other of said images depicts objects in the background of said scene, and wherein said first image is a real image of a first image source and said second image is a virtual image of a second image source, whereby the viewer observing said images perceives the depicted objects as part of a scene having real depth.

7. A method for displaying a three-dimensional scene to a viewer, said method comprising:

simultaneously presenting to both eyes of a viewer a first image that is generally planar;

simultaneously presenting to both eyes of a viewer a second image that is generally planar and is co-aligned with said first image along an axis that is in the general direction of the viewer but at a perceptibly different distance from the viewer than said first image;

wherein the one of said images that is at a distance closer to said viewer depicts objects in the foreground of said three-dimensional scene and the other of said images depicts objects in the background of said scene, and wherein said first image is a real image of a first image source and said second image is a second image source being viewed directly, whereby the viewer observing said images perceives the depicted objects as part of a scene having real depth.

8. A method for displaying a three-dimensional scene to a viewer, said method comprising:

simultaneously presenting to both eyes of a viewer a first image that is generally planar;

simultaneously presenting to both eyes of a viewer a second image that is generally planar and is co-aligned with said first image along an axis that is in the general direction of the viewer but at a perceptibly different distance from the viewer than said first image;

wherein the one of said images that is at a distance closer to said viewer depicts objects in the foreground of said three-dimensional scene and the other of said images depicts objects in the background of said scene, and wherein said first image is a virtual image of a first image source and said second image is a second image source being viewed directly, whereby the viewer observing said images perceives the depicted objects as part of a scene having real depth.

9. A method for displaying a three-dimensional scene to a viewer, said method comprising:

simultaneously presenting to both eyes of a viewer a first image that is generally planar;

simultaneously presenting to both eyes of a viewer a second image that is generally planar and is co-aligned with said first image along an axis that is in the general direction of the viewer but at a perceptibly different distance from the viewer than said first image;

wherein the one of said images that is at a distance closer to said viewer depicts objects in the foreground of said three-dimensional scene and the other of said images depicts objects in the background of said scene, and wherein said first image and said second image are presented to said viewer simultaneously, whereby the viewer observing said images perceives the depicted objects as part of a scene having real depth.
