Abstract

Device for displaying imagery three-dimensionally, which comprises a first image reproduction element having an image reproduction surface and a second image reproduction element having an image indication surface of reflective property. Those image reproduction and indication surfaces are in an opposedly facing relation with each other, such that an imagery reproduced and indicated on the image reproduction surface is reflected by the image indicating surface to form a reflected imagery which is viewed by the eyes of person as if it was a three-dimensional image. One or both of such image reproduction and indication surfaces may be curved to have convex and concave surface sides, wherein the concave surface side is formed to have diffuse reflective property. The convex surface sides respective of those two surfaces may be in an opposedly facing relation with each other. Preferably, such two surfaces may each be a screen of light-transmissive type.

Claims

1. A device for displaying imagery three-dimensionally, comprising:

a first image reproduction means capable of reproducing and indicating a first imagery, said first image reproduction means including an image reproduction surface for allowing said first imagery to be indicated thereon; and

a second image reproduction means capable of reproducing and indicating a second imagery, said second image reproduction means including an image indication surface for allowing said second imagery to be indicated thereon;

wherein said first and second image reproduction means are arranged such that said image reproduction surface of said first image reproduction means is an opposedly facing relation with said image indication surface of said second image reproduction means,

and wherein said image indication surface includes a reflective surface capable of reflecting said first imagery reproduced and indicated from the said first image reproduction means.

2. The device as claimed in claim 1, wherein said image reproduction surface is curved so as to have a convex surface side, whereas said image indication surface is also curved so as to have a convex surface side, and wherein said convex surface sides respectively of said image reproduction and indication surfaces are in an opposedly facing relation with each other.

3. The device as claimed in claim 1, wherein said image reproduction surface is curved so as to have a convex surface side and a concave surface side, whereas said image indication surface is also curved and has a convex surface side and a concave surface side, and wherein said convex surface side of said image reproduction surface is in an opposedly facing relation with said concave surface side of said image indication surface.

4. The device as claimed in claim 1, wherein said image reproduction surface is formed flat, and said image indication surface is curved.

5. The device as claimed in claim 1, wherein said image reproduction surface includes a non-reflective surface portion capable of preventing said second imagery from being reflected thereby.

6. The device as claimed in claim 1, wherein said first and second image reproduction means each comprises one selected from the group consisting of a liquid crystal display device and an organic EL display device.

7. The device as claimed in claim 1, wherein said image reproduction surface is disposed at a point above said image indication surface.

8. The device as claimed in claim 1, which further comprises a light shielding means provided about a periphery of said image reproduction surface.

9. The device as claimed in claim 1, wherein said image reproduction surface and said indication surface are each of a semispherical shape.

10. The device as claimed in claim 1, wherein one of said image reproduction and indication surfaces is of a semishperical shape.

11. The device as claimed in claim 1, wherein said second image reproduction means includes a plurality of said image indication surfaces with respect to said image reproduction surface of said first image reproduction means.

12. The device as claimed in claim 1, wherein said first image reproduction means includes a plurality of said image reproduction surfaces with respect to a plurality of said image indication surfaces of said second image reproduction means.

13. The device as claimed in claim 1, wherein said first image reproduction means comprises:

a first screen of a light-transmissive type which forms said image reproduction surface; and

a first projection means for projecting said first imagery to said first screen, wherein said second image reproduction means comprises;

a second screen of a light-transmissive type which forms said image indication surface; and

a second projection means for projecting said second imagery to said second screen, and wherein said second screen includes a surface so formed as to diffusely reflect said second imagery projected from said second projection means.

14. The device as claimed in claim 13, wherein said first screen is curved so as to have a convex surface side, whereas said second screen is also curved so as to have a convex surface side, and wherein said convex surface sides respectively of said first and second screen are in an opposedly facing relation with each other.

15. The device as claimed in claim 13, wherein said first screen is curved so as to have a convex surface side and a concave surface side, whereas said second screen is also curved so as to have a convex surface side and a concave surface side, and wherein said convex surface side of said first screen is in an opposedly facing relation with said concave surface side of said first screen.

16. The device as claimed in claim 13, wherein said first screen is formed flat, whereas said second screen is curved so as to have a convex surface side, and wherein the thus-flat-formed first screen is in an opposedly facing relation with said convex surface side of said second screen.

17. The device as claimed in claim 13, wherein said first screen includes a non-reflective surface capable of preventing said second imagery from being reflected thereby.

18. The device as claimed in claim 1, which includes a projection means arranged such that one image is projected from the projection means to each of said image reproduction surface and said image indication surface.

19. The device as claimed in claim 13, wherein said first and second projection means each includes a fish-eye lens provided therein.

20. The device as claimed in claim 13, wherein one of said first and second projection means includes a fish-eye lens provided therein.
