5. The multi-layered image display of claim 4 further comprising a second slightly diffuse layer, wherein the second slightly diffuse layer is between the third screen and the first screen or second screen.
6. The multi-layered image display of claim 1 further comprising a refractor, wherein the refractor is between the first screen and the second screen.
7. The multi-layered image display of claim 6 , wherein the refractor comprises a substantially optically clear material and wherein, the first screen, the second screen and the refractor have dimensions and an arrangement such that a line from an edge of the first screen to an edge of the second screen forms an angle of no less than 45 degrees with a face of the second screen.
8. The multi-layered image display of claim 6 , wherein the refractor is a fresnel lens.
9. The multi-layered image display of claim 6 , wherein the refractor is diffuse on a side facing the first screen or the second screen.
10. The multi-layered image display of claim 7 , wherein the refractor is diffuse on a side facing the first screen or the second screen.
11. The multi-layered image display of claim 1 , wherein a distance between the at least one first screen and the second screen is adjustable in real time.
12. A multi-layered image display comprising:
a first screen capable of displaying a first image having a first pixel alignment;
a second screen capable of displaying a second image having a second pixel alignment, wherein the first screen is in front of the second screen; and
the second pixel alignment is 45 degrees with the respect to the first pixel alignment.
13. The multi-layered image display of claim 12 , wherein the first screen is a selectively transparent foreground screen capable of displaying a foreground image and the second screen is a background screen capable of displaying a background image.
14. The multi-layered image display of claim 12 , wherein the first screen is a first selectively transparent foreground screen capable of displaying a first foreground image and the second screen is a second selectively transparent foreground screen capable of displaying a second foreground image.
15. A multi-layered image display comprising:
a first screen capable of displaying a first image;
a second screen capable of displaying a second image, wherein the first screen and the second screen are transmissive polarised display devices; there is no polariser on at least one face of at least the first screen or the second screen; and the first screen is in front of the second screen; and
at least one object between the first screen and the second screen capable of randomizing polarised light.
16. The multi-layered image display of claim 15 , wherein the first screen is a selectively transparent foreground screen capable of displaying a foreground image and the second screen is a background screen capable of displaying a background image.
17. The multi-layered image display of claim 15 , wherein the first screen is a first selectively transparent foreground screen capable of displaying a first foreground image and the second screen is a second selectively transparent foreground screen capable of displaying a second foreground image.
18. The multi-layered image display of one of claims 1 , 12 , or 15 , wherein a selective diffuser layer between the first screen and the second to selectively diffuses light rendering at least one first image or portions thereof opaque.
19. The multi-layered image display of claim 15 , wherein a selective diffuser layer between the first screen and the second screen selectively diffuses polarised light rendering at least one first image or portions thereof transparent.
20. The multi-layered image display of one of claims 1 , 12 , or 15 , wherein the multi-layered image display is capable of receiving images representing image depth extracted from two-dimensional images by a video compression algorithm.
21. The multi-layered image display of claim 20 , wherein the video compression algorithm assigns a depth to a pixel by determining an amount of change in the pixel from an image frame to a successive image frame.
22. The multi-layered image display of claim 20 , wherein the video compression algorithm assigns a depth to a pixel by determining an amount of focus in a subset of pixels.
23. The multi-layered image display of claim 20 , wherein the video compression algorithm assigns a depth to a pixel by determining an amount of sharpness in a subset of pixels.
24. The multi-layered image display of claim 1 , wherein the first screen and the second screen are transmissive polarised display devices; there is no polariser on at least one face of at least the first screen or the second screen; and the first screen is in front of the second screen.
25. The multi-layered image display of claim 24 , wherein the first screen is a selectively transparent foreground screen capable of displaying a foreground image and the second screen is a background screen capable of displaying a background image.
26. The multi-layered image display of claim 24 , wherein the first screen is a first selectively transparent foreground screen capable of displaying a first foreground image and the second screen is a second selectively transparent foreground screen capable of displaying a second foreground image.
27. The multi-layered image display of claim 24 , wherein a selective diffuser layer between the first screen and the second to selectively diffuses light rendering at least one first image or portions thereof opaque.
28. The multi-layered image display of claim 24 , wherein a selective diffuser layer between the first screen and the second screen selectively diffuses polarised light rendering at least one first image or portions thereof transparent.
29. The multi-layered image display of claim 24 , wherein the multi-layered image display is capable of receiving images representing image depth extracted from two-dimensional images by a video compression algorithm.
