Abstract
Abstract A method for generating a three-dimensional spatial image that has a greatly improved three-dimensional (3-D) effect. The method utilizes a series of two dimensional stereoscopic image pairs which have been composed by different scenes photographed on different bases or computer generated using a single channel or multi-channel optical image projector, beam splitter, camera, and a retro-reflective screen.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
84 words
A method for generating a 3-D spatial image display that has a background scene and foreground objects, said method comprising the steps of: generating a series of stereoscopic image pairs of a background scene from different positions around the scene which image pairs will form the background scene of the final image display; and synthesizing the foreground objects with the said series of projected stereoscopic background image pairs to produce a new series of stereoscopic pairs including both foreground objects and the background scene.
Claim 2
Independent Claim
84 words
A method for generating a 3-D spatial image display that has a background scene and foreground objects, said method comprising the steps of: generating a series of stereoscopic image pairs of a background scene from different positions around the scene which image pairs will form the background scene of the final image display; and synthesizing the foreground objects with the said series of projected stereoscopic background image pairs to produce a new series of stereoscopic pairs including both foreground objects and the background scene.
Claim 3
Dependent Claim
35 words
The method of claim 1 in which the synthesizing step includes projecting each image of the background scene in sequence onto a screen to produce the series of stereoscopic image pairs of a background scene.
Claim 4
Dependent Claim
32 words
The method of claim 1 in which the synthesizing step includes projecting the images of the background scene simultaneously onto a screen to produce the stereoscopic image pairs of the background scene.
Claim 5
Dependent Claim
69 words
The method of claim 1 in which the synthesizing step includes projecting each image of the background scene through a beam splitter and onto the foreground objects, reflecting the split images back to a camera to create a series of 2-D stereoscopic picture pairs that include both the background scene and foreground objects, and projecting the said picture pairs onto a screen to generate 3-D spatial images for viewing.
Claim 6
Dependent Claim
31 words
The method of claim 4 in which a one-channel projector is used for generating the 3-D spatial images, and said projector is moved along a path fixed relative to the screen.
Claim 7
Dependent Claim
34 words
The method of claim 4 in which a multi-channel projector is used for generating the 3-D spatial images, and the position of said projector is fixed at a predetermined place relative to the screen.
