Abstract

A display system is capable of displaying images of high resolution on a main screen, and augmentation images in augmentation regions located around the main screen. The viewing experience is enhanced by the presence of the augmentation images because of the increase in visual information conveyed to viewers. The augmentation regions lie outside of the foveal field of view of the viewers, so the augmentation images can be of lower resolution than the high resolution images. The use of lower resolution augmentation images reduces the cost of the display system.

Claims

1. A method of displaying images, comprising:

generating a high resolution display signal;

determining at least one of a motion, brightness or color characteristic from the high resolution display signal;

generating at least one augmentation display signal using the at least one motion, brightness or color characteristic;

displaying a high resolution image using the high resolution display signal; and

displaying at least one augmentation image using the at least one augmentation display signal.

2. The method of claim 1, wherein the step of displaying a high resolution image comprises:

projecting a high resolution image onto a screen.

3. The method of claim 2, wherein the step of displaying at least one augmentation image comprises:

projecting at least one augmentation image onto at least one augmentation region.

4. The method of claim 3, wherein the at least one augmentation region comprises a plurality of augmentation regions disposed around the screen, the step of projecting at least one augmentation image onto at least one augmentation region comprising:

projecting an augmentation image onto an augmentation region to the right of the screen; and

projecting an augmentation image onto an augmentation region to the left of the screen.

5. The method of claim 4, wherein the step of projecting at least one augmentation image onto at least one augmentation region comprises:

projecting an augmentation image onto an augmentation region above the screen.

6. The method of claim 3, wherein the step of projecting at least one augmentation image onto at least one augmentation region comprises:

illuminating an array of red, blue and green lights.

7. The method of claim 6, wherein the step of projecting at least one augmentation image onto at least one augmentation region comprises:

illuminating an array of white lights.

8. The method of claim 1, wherein the at least one augmentation display signal comprises a plurality of augmentation display signals, the step of displaying at least one augmentation image using the at least one augmentation display signal comprising:

illuminating a plurality of arrays arranged around the high resolution image.

9. The method of claim 8, wherein the step of displaying a high resolution image comprises:

projecting a high resolution image onto a screen, the arrays comprising an array mounted to the left of the screen, an array mounted to the right of the screen, and an array mounted above the screen.

10. The method of claim 9, wherein the step of illuminating a plurality of arrays comprises:

illuminating red, blue and green lights of the arrays.

11. The method of claim 10, wherein the step of illuminating a plurality of arrays comprises:

illuminating white lights of the arrays.

13. The display system of claim 12, wherein the at least one augmentation projector comprises a plurality of augmentation projectors, wherein the augmentation projectors are arranged to project augmentation images onto a plurality of augmentation regions disposed around the main screen.

14. The display system of claim 13, wherein at least one of the augmentation projectors includes:

an array of red, blue and green lights.

15. The display of claim 14, wherein at least one of the augmentation projectors includes:

an array of white lights.

16. The display system of claim 13, wherein the main screen is disposed on a front wall of a room, an augmentation region is disposed on a side wall to the left of the front wall, an augmentation region is disposed on a side wall to the right t of the front wall, and an augmentation region is disposed on a ceiling above the front wall.

18. The display system of claim 17, wherein the at least one array comprises a plurality of arrays, wherein the arrays are arranged to display augmentation images at a plurality of regions disposed around the main screen.

19. The display system of claim 18, wherein at least one of the arrays includes:

an array of red, blue and green lights.

20. The display of claim 19, wherein at least one of the arrays includes:

an array of white lights.

21. The display system of claim 18, wherein the main screen is disposed on a front wall of a room, an array is disposed on a side wall to the left of the front wall, an array is disposed on a side wall to the right of the front wall, and an array is disposed on a ceiling above the front wall.

12. A display system, comprising:

a main screen;

a main projector, wherein the main projector is arranged to project images on the main screen;

at least one augmentation projector, wherein the at least one augmentation projector is arranged to project at least one augmentation image onto at least one augmentation region; and

a control, wherein the control is operatively connected to the main projector to provide high resolution display signals to the main projector, and operatively connected to the at least one augmentation projector to provide augmentation display signals to the at least one augmentation projector, the augmentation display signals being keyed to at least one of the color, motion, and brightness of the high resolution display signals.

17. A display system, comprising:

a main screen;

a main projector, wherein the main projector is arranged to project images on the main screen;

at least one array, wherein the at least one array is arranged to display at least one augmentation image; and

a control, wherein the control is operatively connected to the main projector to provide high resolution display signals to the main projector, and operatively connected to the at least one array to provide augmentation display signals to the at least one array, the augmentation display signals being keyed to at least one of the color, motion, and brightness of the high resolution display signals.
