Abstract
Abstract Image compositing apparatus and methodology for the creation, in a defined volume of three-dimensional space, of a composite organization of plural images/visual phenomena, including at least one projected real image, displayed in formats including (a) front-to-rear, (b) side-by-side and (c) overlapping and intersecting, adjacency. The apparatus incorporates different unique arrangements of visual sources, and optical elements including concave reflectors, beam splitters and image-forming/image-transmissive scrim/screen structures. In one important modification of the system, which does not necessarily require compositing, a projected real image is derived from an image-producing data stream containing three-dimensional image cues selected from the group consisting of shading, occlusion, perspective, motion parallax, size vs. depth, light (chroma value) vs. depth and definition vs. depth. In a further important modification of the invention, a system is proposed which allows a viewer/user to interact directly with a projected real image, in a manner allowing the manipulation of one or more characteristics or aspects of the image.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
228 words
A visual display apparatus comprising a visual staging station defining a space for viewing images from a vantage point along a viewing axis, a beam splitter located along the viewing axis in said space, the beam splitter having a front side partially facing the vantage point, and a back side opposite from the front side, wherein the beam splitter is oriented obliquely relative to the viewing axis, a first image source equipped and positioned to display a first image directed toward the front side of the beam splitter so that, to a person viewing the staging station from the vantage point, the first image appears to be a background image located behind the beam splitter substantially along the viewing axis, a second image source equipped and positioned to display a second image directed along the path leading toward and through the backside of the beam splitter along the viewing axis toward the vantage point, and an optical structure located along the path between the second image source and the beam splitter, wherein the optical structure causes divergent rays from the second image to converge substantially along the viewing axis in front of the beam splitter, so that, to a person viewing the staging station from the vantage point, the second image appears as a floating real image in front of both the beam splitter and the background image.
Claim 2
Dependent Claim
228 words
A visual display apparatus comprising a visual staging station defining a space for viewing images from a vantage point along a viewing axis, a beam splitter located along the viewing axis in said space, the beam splitter having a front side partially facing the vantage point, and a back side opposite from the front side, wherein the beam splitter is oriented obliquely relative to the viewing axis, a first image source equipped and positioned to display a first image directed toward the front side of the beam splitter so that, to a person viewing the staging station from the vantage point, the first image appears to be a background image located behind the beam splitter substantially along the viewing axis, a second image source equipped and positioned to display a second image directed along the path leading toward and through the backside of the beam splitter along the viewing axis toward the vantage point, and an optical structure located along the path between the second image source and the beam splitter, wherein the optical structure causes divergent rays from the second image to converge substantially along the viewing axis in front of the beam splitter, so that, to a person viewing the staging station from the vantage point, the second image appears as a floating real image in front of both the beam splitter and the background image.
Claim 3
Dependent Claim
16 words
The display apparatus of claim 1, wherein the optical structure includes at least one curved mirror.
Claim 4
Dependent Claim
13 words
The display apparatus of claim 1, wherein the optical structure includes plural mirrors.
Claim 5
Dependent Claim
16 words
The display apparatus of claim 1, wherein the optical structure includes at least one parabolic mirror.
Claim 6
Dependent Claim
20 words
The display apparatus of claim 1, wherein the beam splitter forms about a 45-degree angle relative to the viewing axis.
Claim 7
Dependent Claim
21 words
The display apparatus of claim 1, wherein the first image source faces in a direction substantially perpendicular to the viewing axis.
Claim 8
Dependent Claim
20 words
The display apparatus of claim 1, wherein the optical structure includes an element which is at least partially light transmissive.
Claim 9
Dependent Claim
19 words
The display apparatus of claim 1 further comprising a housing for substantially encasing the image sources and optical structure.
Claim 10
Dependent Claim
69 words
The display apparatus of claim 1, wherein the second image source is provided with a data stream containing three-dimensional image cues selected from the group consisting of shading, occlusion, perspective, motion parallax, size versus depth, light versus depth and definition versus depth, and combinations thereof, so that the floating real image in front of the beam splitter appears to be three-dimensional from the vantage point along the viewing axis.
Claim 11
Dependent Claim
28 words
The display apparatus of claim 1 further comprising a control mechanism which allows a viewer to interact with the floating real image in front of the beam splitter.
