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.
Claims5
An image display system comprising:
- a composite image source, a portion of the composite image source being
- a first image source, and another portion of the composite image source being
- a second image source;
- a beamcombiner;
- a single lens;
- and
- a reflective element disposed to reflect the image of said second image source to said beamcombiner;
- wherein said first image source, said second image source, said beamcombiner, and said single lens are so disposed as to present to a viewer a foreground image from one of said image sources, and a background image from the other of said image sources, the background image being presented at a greater distance from the viewer than the foreground image, at least one of the images being a real image or virtual image presented by the single lens;
- whereby the viewer perceives the foreground image and the background image as part of a scene having depth.
An image display system comprising:
- a foreground image source;
- a background image source;
- a beamcombiner;
- and
- a mask interposed between said background image source and said beamcombiner;
- wherein said foreground image source, said background image source, and said beamcombiner are so disposed as to present to a viewer a foreground image from the foreground image source, and a background image from the background image source, the background image being presented at a greater distance from the viewer than the foreground image;
- wherein said foreground image source and said mask are the same distance from said beamcombiner;
- and
- wherein said mask displays a silhouette of foreground objects that appear coincident with said foreground image source,
- whereby the viewer perceives the foreground image and the background image as part of a scene having depth, and
- whereby said mask acts to mask portions of the background image from the viewer so as to improve presentation of foreground objects.
An image display system comprising:
- a first image source;
- a second image source;
- a beamcombiner;
- and
- a single lens;
- wherein said first image source, said second image source, and said beamcombiner are so disposed as to present to a viewer a foreground image from one of said image sources, and a background image from the other of said image sources, the background image being presented at a greater distance from the viewer than the foreground image, and
- wherein said lens is interposed between said first image source and the viewer so as to present at least one of the foreground image and the background image as a real image,
- whereby the viewer perceives the foreground image and the background image as part of a scene having depth.
