Abstract

A method for displaying a substantially realistic image of an object for a plurality of viewers located in different positions includes defining a particular position in a room for each viewer and generating, based on the position, an image of the object representing the perspective view of the particular viewer.

Claims

1. A method for displaying a multidimensional image of an object for a plurality of viewers, the method comprising:

defining a respective position in a space for each of the plurality of viewers; and

generating a respective image of the object representing a respective perspective view for each of the plurality of viewers using the respective position.

2. The method as recited in

claim 1

wherein the generating the respective image for each of the plurality of viewers is performed by filtering a respective plurality of spectral regions out of a radiation spectrum of an image-display device.

3. The method as recited in

claim 2

wherein the filtering the respective plurality of spectral regions out of the radiation spectrum is performed by decoupling respective narrowband frequency bands.

4. The method as recited in

claim 3

wherein the narrow frequency bands are each approximately 5 to 20 nm wide.

5. The method as recited in

claim 1

wherein each of the respective image includes two respective half-images.

6. The method as recited in

claim 5

wherein the generating the respective image for each of the plurality of viewers is performed by generating a respective plurality of spectral regions, each respective plurality of spectral regions including respective first and second adjacent spectral regions, and further comprising decoupling each of the respective first and second adjacent spectral regions so as to form each of the two respective half-images.

7. The method as recited in

claim 5

further comprising displaying each of the respective two half-images according to a respective clock sequence.

8. The method as recited in

claim 6

further comprising displaying each of the respective two half-images according to a respective clock sequence.

9. The method as recited in

claim 7

wherein the generating the respective image for each of the plurality of viewers is performed by generating a respective plurality of spectral regions, and wherein each of the respective clock sequence is the same, and further comprising decoupling each of the respective plurality of spectral regions.

10. The method as recited in

claim 8

wherein each of the respective clock sequence is the same.

11. The method as recited in

claim 7

wherein the generating the respective image for each of the plurality of viewers is performed by generating a respective plurality of spectral regions, and wherein each of the respective clock sequence is different, and further comprising decoupling each of the respective plurality of spectral.

12. The method as recited in

claim 8

wherein each of the respective clock sequence is different and further comprising decoupling each of the respective plurality of spectral regions.

13. The method as recited in

claim 1

wherein the space is a room.

14. A device for displaying a multidimensional image of an object for a plurality of viewers, the device comprising:

a respective image pick-up device associated with each of the plurality of viewers;

a respective measuring device associated with each of the plurality of viewers for determining a respective position of the respective viewer in a space; and

a plurality of image-display devices for displaying a respective image of the object representing a respective perspective view of each of the plurality of viewers using the respective position of the respective viewer.

15. The device as recited in

claim 14

each of the respective image pick-up device includes a respective pair of eyeglasses.

16. The device as recited in

claim 14

further comprising at least one predefinable interference filter for generating each of the respective image.

17. The device as recited in

claim 14

further comprising a respective liquid crystal shutter associated with each of the plurality of viewers.

18. The device as recited in

claim 14

wherein the space is a room.
