Abstract

To contrive a reduction in the overall size of the device in the case of arranging at least two screens, to reduce color shading of a 3-dimensional image, and thereby to give a further absorbedness feeling to the viewer. A 3-dimensional image display device includes a space partitioned by a frame assembled in a box shape, the space accommodating a plurality of viewers, three screens disposed so as to partition the space, three projectors disposed correspondingly to the screens, respectively, and a controller for supplying image data to the projectors and further includes a phase plate disposed between the first projector and the front screen, and further, a phase plate disposed between the third projector and a reflective mirror member.

Claims

1. A 3-dimensional image display device comprising:

at least a first and second image projector;

at least a first and second screen disposed correspondingly to said first and second image projectors for projecting thereon images from said first and second image projectors;

a controller for outputting image data for a 3-dimensional display according, respectively, from said first and second image projectors to said first and second screens;

a first projection system in which an image from said first image projector is projected directly onto said first screen;

a second projection system in which an image from said second image projector is projected onto said second screen through reflection by a reflective member;

at least one set of said image projectors and said screens including a polarizing means for polarizing light, said polarizing means being disposed between said image projector and said screen.

2. The 3-dimensional image display device as set forth in claim 1, wherein

said polarizing means is disposed between said first image projector and said first screen.

3. The 3-dimensional image display device as set forth in claim 1, wherein

said polarizing means is disposed between said second image projector and said second screen.

4. The 3-dimensional image display device as set forth in claim 1, wherein said controller outputs image data for a 3-dimensional display according to the positions of said screens and a viewer.

5. The 3-dimensional image display device as set forth in claim 2, wherein said controller outputs image data for a 3-dimensional display according to the positions of said screens and a viewer.

6. The 3-dimensional image display device as set forth in claim 3, wherein said controller outputs image data for a 3-dimensional display according to the positions of said screens and a viewer.

7. The 3-dimensional image display device as set forth in claim 1, and further including liquid crystal shutter spectacles adapted to be worn by a viewer for perceiving said 3-dimensional image.

8. The 3-dimensional image display device as set forth in claim 7, and further including a magnetic field generator operatively disposed relative to said first and second screens for generating a magnetic field and a magnetic-type position sensor operatively disposed within said liquid crystal shutter spectacles for outputting a position of a viewer relative to said first and second screens.

9. The 3-dimensional image display device as set forth in claim 1, and further including a third image projector and a third screen disposed correspondingly to said third image projector for projecting an image from the third image projector.

10. The 3-dimensional image display device as set forth in claim 9, and further including a polarizing means for polarizing the light projected from said third image projector, said polarizing means being disposed between the third image projector and the third screen.

11. A 3-dimensional image display equipment comprising:

a mobile body having a closed space;

a 3-dimensional image display device installed in said closed space of said mobile body;

at least a first and second image projector;

at least a first and second screen disposed correspondingly to said first and second image projectors for projecting thereon images from said first and second image projectors; and

a controller for outputting image data adjusted to the left and right eyes of a viewer according, respectively, from said first and second image projectors to said first and second screens.

12. The 3-dimensional image display equipment as set forth in claim 11, wherein said polarizing means is disposed between said first image projector and said first screen.

13. The 3-dimensional image display equipment as set forth in claim 11, wherein said polarizing means is disposed between said second image projector and said second screen.

14. The 3-dimensional image display equipment as set forth in claim 11, wherein said controller outputs image data for a 3-dimensional display according to the positions of said screens and a viewer.

15. The 3-dimensional image display equipment as set forth in claim 12, wherein said controller outputs image data for a 3-dimensional display according to the positions of said screens and a viewer.

16. The 3-dimensional image display equipment as set forth in claim 13, wherein said controller outputs image data for a 3-dimensional display according to the positions of said screens and a viewer.

17. The 3-dimensional image display equipment as set forth in claim 11, and further including liquid crystal shutter spectacles adapted to be worn by a viewer for perceiving said 3-dimensional image.

18. The 3-dimensional image display equipment as set forth in claim 17, and further including a magnetic field generator operatively disposed relative to said first and second screens for generating a magnetic field and a magnetic-type position sensor operatively disposed within said liquid crystal shutter spectacles for outputting a position of a viewer relative to said first and second screens.

19. The 3-dimensional image display equipment as set forth in claim 11, and further including a third image projector and a third screen disposed correspondingly to said third image projector for projecting an image from the third image projector.

20. The 3-dimensional image display equipment as set forth in claim 19, and further including a polarizing means for polarizing the light projected from said third image projector, said polarizing means being disposed between the third image projector and the third screen.
