The perception of a displayed image is altered for viewers moving relative to the position of the display system screen, thereby imparting a sense of three-dimensional immersion in the scene being displayed. A display generator generates a scene having foreground and background elements, and a display screen displaying the scene. A sensor detects the position of a viewer relative to the display screen, and a processor is operative to shift the relative position of the foreground and background elements in the displayed scene as a function of viewer position, such that the viewer's perspective of the scene changes as the viewer moves relative to the display screen. The foreground and background elements may be presented in the form of multiple superimposed graphics planes, and/or a camera may be used to record the scene through panning at sequential angles. The system may be used to implement virtual windows, virtual mirrors and other effects without requiring viewers or users to modify behavior or wear glasses, beacons, etc.

1. A perspective-altering display system, comprising: a display screen for displaying a scene having opposing side edges;a sensor for detecting the movement of a viewer relative to the display screen;at least one memory for storing foreground and background imagery;wherein the memory has a capacity to store imagery that extends beyond one or both of the side edges of the display screen;at least one processor interconnected to the memory and the sensor, the processor being operative to perform the following functions: generate a scene based upon multiple superimposed graphics planes, including a foreground graphics plane containing the foreground imagery and a background graphics plane containing the background imagery, andreceive a signal from the sensor and shift the relative position of the foreground and background graphics planes in the displayed scene as a function of viewer movement;wherein the multiple superimposed graphics planes include non-visible imagery beyond one of both of the side edges display screen; andwherein the foreground graphics plane is shifted by way of a translation to a greater extent than the background graphics plane as a viewer moves from side to side relative to the display screen, causing the non-visible imagery to become visible. 2. The display system of claim 1, wherein at least one of the graphics planes includes prerecorded imagery. 3. The display system of claim 1, wherein at least one of the graphics planes includes imagery received through a transmission medium. 4. The display system of claim 1, wherein at least one of the graphics planes includes imagery received from a camera. 5. The display system of claim 1, wherein at least one of the graphics planes includes textual information. 6. The display system of claim 1, further including: a camera that records the scene through panning at sequential angles; andwherein the memory stores imagery obtained at the sequential angles for later recall as a function of user movement. 7. The display system of claim 6, further including: an interpolator for filling in visual gaps in the scene. 8. The display system of claim 1, wherein: the display screen is mounted on a wall having a backside; andfurther including a camera mounted on the backside of the wall which pans as a viewer moves, thereby imaging a scene representative of the display being a virtual window through the wall. 9. The display system of claim 1, further including: a camera with a zoom capability for recording the scene;the sensor being operative to detect the viewer's distance from the display screen; andwherein the processor is further operative to zoom in the camera as the viewer moves closer to the display screen and zoom out the camera as the viewer moves away from the display screen. 10. The display system of claim 1, wherein: the sensor is operative to detect the viewer's distance from the display screen; andthe processor is operative to increase the resolution of the scene as the viewer moves closer to the display screen and decrease the resolution of the scene as the viewer moves away from the display screen. 11. The display system of claim 1, further including: a camera with a tilt capability for recording the scene;the sensor being operative to detect the viewer's up/down movement relative to the display screen; andwherein the processor is further operative to tilt the camera in response to the viewer's up/down movement. 12. The display system of claim 1, further including: a camera for recording the scene, the camera having a field of view including a viewer of the display screen; andwherein the processor is further operative to flip the scene horizontally such that the display functions as a virtual mirror. 13. The display system of claim 1, further including: a plurality of cameras for recording the scene; andwherein the processor is further operative to construct a three-dimensional image for display on the screen. 14. The display system of claim 1, further including: a plurality of cameras for recording the scene;the processor being further operative to construct a three-dimensional image for display on the screen; anda user control a viewer to select a specific camera or cameras to see how others would view the user from different perspectives. 15. The display system of claim 1, wherein the sensor is an infrared CCD (charge-coupled device) camera. 16. The display system of claim 1, wherein: the sensor is a camera having an image sensor; andan image of a person in front of the display is focused onto the image sensor as a spot or group of pixels, allowing the movements of the person to be tracked with no moving parts. 17. The display system of claim 1, wherein: the sensor is a camera having at least a pan mount that tracks the movement of a viewer; andthe processor is operative to shift the relative position of the foreground and background elements as a function of the tracking. 18. The display system of claim 1, wherein: the sensor is a camera having a pan/tilt mount that tracks the movement of a viewer;the processor is operative to shift the relative position of the foreground and background elements as a function of the tracking. 19. The display system of claim 1, wherein: the sensor is a camera having an auto-focus capability to track the movement of a viewer;the processor is operative to shift the relative position of the foreground and background elements as a function of the tracking. 20. The display system of claim 1, wherein: the sensor is operative to sense a plurality of individuals in front of the display screen; andthe processor is operative to shift the relative position of the foreground and background elements by favoring clusters of individuals. 21. The display system of claim 1, wherein: the sensor is operative to sense a plurality of individuals in front of the display screen; andthe processor is operative to shift the relative position of the foreground and background elements by favoring moving individuals over stationary individuals. 22. The display system of claim 1, wherein: the sensor is operative to sense a whether an individual is looking toward the display screen; andthe processor is operative to shift the relative position of the foreground and background elements by favoring individuals looking toward the display screen. 23. The display system of claim 1, further including one or more transducers for producing sounds associated with the scene; and the processor is operative to alter the reproduction of the sounds as a function of viewer movement.
