Abstract

The present invention provides a multi-projection system including a plurality of projection surfaces, on which images are projected, which are arranged to surround an auditorium, and the plurality of projection surfaces comprise different types of projection surfaces. According to the present invention, it is possible to provide an audience with an image with high three-dimensional effect and immersion and provide images of multiple viewpoints such that the audience can feel as if they are in a space created by the images.

Claims

1. A multi-projection system comprising a plurality of projection surfaces, on which images are projected, which are arranged to surround an auditorium, wherein the plurality of projection surfaces comprise different types of projection surfaces.

2. The multi-projection system of claim 1, wherein the projection surface is formed with a screen, an interior surface of a theater, or a surface of an internal fixture of the theater.

3. The multi-projection system of claim 2, wherein the plurality of projection surfaces comprise different types of screens.

4. The multi-projection system of claim 2, wherein the plurality of projection surfaces comprise different types of interior surfaces of the theater.

5. The multi-projection system of claim 2, wherein the plurality of projection surfaces comprise different types of surfaces of internal fixtures of the theater.

6. The multi-projection system of claim 2, wherein the plurality of projection surfaces comprise both the projection surface formed with the screen and the projection surface formed with the interior surface of the theater.

7. The multi-projection system of claim 6, wherein the plurality of projection surfaces comprise a screen arranged in front of the theater and walls arranged on the left and right sides of the screen.

8. The multi-projection system of claim 7, wherein the plurality of projection surfaces further comprise a ceiling or floor.

9. The multi-projection system of claim 2, wherein the plurality of projection surfaces comprise both the projection surface formed with the screen and the projection surface formed with the surface of the internal fixture of the theater.

10. The multi-projection system of claim 9, wherein the plurality of projection surfaces further comprise a projection surface formed with a ceiling or floor.

11. The multi-projection system of claim 2, wherein the interior surface of the theater or the surface of the internal fixture of the theater comprises an optical paint for optical reflection applied thereon.

12. The multi-projection system of claim 1, wherein when the types of the projection surfaces are different, the image projected on each projection surfaces is corrected based on the type of each projection surface.

13. The multi-projection system of claim 12, wherein the correction is made based on the color of the projection surface.

14. The multi-projection system of claim 12, wherein the correction is made based on the material of the projection surface.

15. The multi-projection system of claim 12, wherein the correction is made based on the type of the projection surface.

16. The multi-projection system of claim 12, wherein the correction is made based on the distance between a projection surface and a projection or based on the angle at which the image is projected.

17. The multi-projection system of claim 1, wherein the interior surface of the theater comprises a sound absorbing material.

18. The multi-projection system of claim 17, wherein the sound absorbing material comprises at least one selected from the group consisting of a porous molded sound absorbing material, a plate vibration-type sound absorbing material, and a resonance-type sound absorbing material.

19. The multi-projection system of claim 1, wherein the plurality of projection surfaces are arranged on at least two sides that are not parallel to each other, and the number of projection surfaces arranged on a specific side is at least one.

20. The multi-projection system of claim 2, wherein the plurality of projection surfaces comprise both the projection surface formed with the interior surface of the theater and the projection surface formed with the surface of the internal fixture of the theater.
