Abstract

A method for creating a distance dependent display that comprises providing an image separating mask having a plurality precision slits arranged in a pattern, generating an interlaced image from a plurality of images according to the pattern, and combining the interlaced image and the image separating mask to allow an observer to view substantially separately each the image from a respective of a plurality of different distances from the image separating mask.

Claims

1. A method for creating a distance dependent display, comprising:

providing an image separating mask having a plurality precision slits arranged in a pattern;

generating an interlaced image from a plurality of images according to said pattern; and

combining said interlaced image and said image separating mask to allow an observer to view substantially separately each said image from a respective of a plurality of different distances from said image separating mask.

2. The method of claim 1, wherein said pattern is irregular.

3. The method of claim 2, wherein said irregular pattern is selected from a group consisting of:

an asymmetric pattern of opaque and transparent sub-areas, a pattern having opaque segments with variable widths, a pattern having transparent segments with variable widths, and a pattern in which the various segments having variable opacities.

4. The method of claim 1, wherein said plurality of precision slits comprises a member selected from the group consisting of linear slits, curved slits, annular slits, twisted slits, spiraling slits and/or kinked slits.

5. The method of claim 1, wherein said combining comprises attaching said interlaced image to a side of a transparent surface and said image separating mask to an opposing side of said transparent surface.

6. The method of claim 1, wherein said providing comprises arranging said plurality of precision slits according to a binary image.

7. The method of claim 1, wherein each said image having at least one of a different hue and a different color, wherein the hue perceived from each said distance is different.

8. A distance dependent display, comprising:

an image separating mask having a plurality of precision slits arranged in a pattern; and

an interlaced image from a plurality of images, each said image being interlaced to match said pattern;

wherein said interlaced image and said plurality of precision slits are aligned to allow an observer to view substantially separately each said image from a respective of a plurality of different distances from said image separating mask.

9. The distance dependent display of claim 8, further comprising a transparent surface, said transparent surface said interlaced image and said image separating mask being attached to opposite sides of said transparent surface.

10. The distance dependent display of claim 9, further comprising an attachment element for attaching the distance dependent display to a window.

11. The distance dependent display of claim 9, wherein said image separating mask comprises a member of a group consisting of:

a parallax barrier, a grating, and an optical barrier.

12. The distance dependent display of claim 9, wherein said image separating mask is an optical barrier, said plurality of precision slits comprising a member of a group consisting of lenticular lenses, diffractive elements, and lenses for integral photography.

13. A method for creating an integral viewing sheet, comprising:

providing an image separating mask having a plurality of precision slits arranged in a predefined pattern that applies an estimated blur;

interlacing a plurality of images to form an interlaced image according to said predefined pattern, at least one of said interlaced image and plurality of images being processed according to said estimated blur; and

creating an integral viewing sheet by fixating said image separating mask in parallel to said interlaced image.

14. The method of claim 13, wherein said predefined pattern is irregular.

15. The method of claim 14, wherein said irregular pattern is selected from a group consisting of:

an asymmetric pattern of opaque and transparent sub-areas, a pattern having opaque segments with variable widths, a pattern having transparent segments with variable widths, and a pattern in which the various segments having variable opacities.

16. The method of claim 13, wherein said image separating mask has a transparent-opaque ratio of at least 1:

1.

17. The method of claim 13, wherein said interlaced image comprises a plurality of strips, at least one of said plurality of precision slits being wider than each said strip.

18. An article for viewing images of an interlaced image, comprising:

an image separating mask having a plurality of precision slits arranged in an irregular pattern; and

an interlaced image from a plurality of images, each said image being interlaced to match said irregular pattern;

wherein said interlaced image and said plurality of precision slits are combined to allow an observer to view substantially separately each said image from a respective of a plurality of various viewing positions from said image separating mask.

19. The article of claim 18, wherein said irregular pattern is selected from a group consisting of:

an asymmetric pattern of opaque and transparent sub-areas, a pattern having opaque segments with variable widths, a pattern having transparent segments with variable widths, and a pattern in which the various segments having variable opacities.

20. The article of claim 18, further comprising a backlight element for illuminating interlaced image via said image separating mask, said interlaced image being positioned between said observer and said image separating mask.
