Abstract

The present invention multi-plane display system discloses a three dimension display system comprising at least two display surfaces, one of which displaying a three dimensional horizontal perspective images. Further, the display surfaces can have a curvilinear blending display section to merge the various images. The multi-plane display system can comprise various camera eyepoints, one for the horizontal perspective images, and optionally one for the curvilinear blending display surface.

Claims

1. A horizontal perspective display system comprising

a first display to display horizontal perspective images according to a predetermined projection eyepoint;

and

a second display positioned at an angle to the first display.

2. A display system as in claim 1 wherein the second display displays 2D images or central perspective images.

3. A display system as in claim 1 further comprising a third curvilinear display blending the first and the second displays.

4. A display system as in claim 1 further comprising

an eyepoint input device for accepting an input eyepoint location wherein the horizontal perspective images can be adjusted using the input eyepoint as the projection eyepoint.

5. A display system as in claim 4 wherein the eyepoint input device is a manual input device whereby the eyepoint input location is manually entered.

6. A display system as in claim 4 wherein the eyepoint input device is an automatic input device whereby the automatic input device automatically extracts the eyepoint location from the viewer.

7. A horizontal perspective display system comprising

a first real time display to display horizontal perspective images according to a predetermined projection eyepoint;

a second display positioned at an angle to the first display;

an eyepoint input device for accepting an input eyepoint location; and

a computer system for receiving the input eyepoint location from the eyepoint input device, calculating the horizontal perspective projection images according to the input eyepoint location, and outputting the images to the first display;

wherein the displayed images is real time adjusted using the input eyepoint as the projection eyepoint.

8. A display system as in claim 7 wherein the eyepoint input device is a manual input device whereby the eyepoint input location is manually entered.

9. A display system as in claim 7 wherein the manual input device is a computer peripheral or a wireless computer peripheral.

10. A display system as in claim 7 wherein the manual input device is selected from a group consisted of a keyboard, a stylus, a keypad, a computer mouse, a computer trackball, a tablet, a pointing device.

11. A display system as in claim 7 wherein the eyepoint input device is an automatic input device whereby the automatic input device automatically extracts the eyepoint location from the viewer.

12. A display system as in claim 11 wherein the automatic input device is selected from a group consisted of radio-frequency tracking device, infrared tracking device, camera tracking device.

13. A display system as in claim 7 further comprising a third curvilinear display blending the first and the second displays.

14. A display system as in claim 7 wherein the horizontal perspective image is stereoscopic images.

15. A display system as in claim 7 wherein the displayed image is continuously updated to form motion images.

16. A display system as in claim 7 further comprising

an image input device for accepting an image command;

wherein the computer system further accepts an image command from the image input device, and further calculates a horizontal perspective projection image according to the image command using the input eyepoint location as the projection eyepoint before outputting the image to the first display.

17. A display system as in claim 16 wherein the image command includes image magnification, image movement, image rotation command and command to display another predetermined image.

18. A horizontal perspective display system comprising

a first real time display to display horizontal perspective images according to a predetermined projection eyepoint;

a second display positioned at an angle to the first display;

a third curvilinear display blending the first and the second displays;

an eyepoint input device for accepting an input eyepoint location; and

a computer system for receiving the input eyepoint location from the eyepoint input device, calculating the horizontal perspective projection images according to the input eyepoint location, and outputting the images to the first display;

wherein the displayed images is real time adjusted using the input eyepoint as the projection eyepoint.

19. A display system as in claim 18 further comprising

an image input device for accepting an image command;

wherein the computer system further accepts an image command from the image input device, and further calculates a horizontal perspective projection image according to the image command using the input eyepoint location as the projection eyepoint before outputting the image to the first display.

20. A display system as in claim 19 wherein the image command includes image magnification, image movement, image rotation command and command to display another predetermined image.
