Abstract

The present invention provides a multi-projection system including a plurality of projection surfaces arranged in a single theater so as not to be parallel to each other, wherein the plurality of projection surfaces may comprise a projection surface including a non-solid material.

Claims

1. A multi-projection system composing a plurality of projection surfaces arranged in a single theater so as not to be parallel to each other, wherein the plurality of projection surfaces comprise a projection surface including a non-solid material.

2. The multi-projection system of claim 1, wherein the plurality of projection surfaces comprise a fog screen or water screen.

3. The multi-projection system of claim 2, further comprising:

one or more projection devices for projecting images on the plurality of projection surfaces; and

a management device for controlling the one or more projection devices.

4. The multi-projection system of claim 3, further comprising a fog generator for forming the fog screen on a front, ceiling, side, or floor of the single theater.

5. The multi-projection system of claim 4, wherein the fog generator comprises a partition for guiding the flow of fog.

6. The multi-projection system of claim 4, wherein the management device controls the fog generator and the projection device, which projects an image on the fog screen, to operate in conjunction with each other.

7. The multi-projection system of claim 6, wherein the fog generator and the projection device, which projects an image on the fog screen, operate in conjunction with each other based on a control signal transmitted from the management device, the projection device operating after the fog generator operates.

8. The multi-projection system of claim 4, further comprising a fog inhaler for inhaling the generated fog, wherein the fog inhaler is controlled by the management device.

9. The multi-projection system of claim 3, wherein the water screen is formed on a front, or floor of the single theater.

10. The multi-projection system of claim 9, further comprising, when the water screen in formed on the floor of the theater:

a water tank filled with a liquid; and

a bubble generator for generating bubbles in the liquid.

11. The multi-projection system of claim 10, wherein the management device controls the bubble generator and the projection device, which projects an image on the surface of the liquid, to operate in conjunction with each other.

12. The multi-projection system of claim 9, further comprising, when the water screen is formed on the side of the theater, a liquid injector for injecting a liquid into a space, wherein the liquid injector is controlled by the management device.

13. The multi-projection system of claim 12, wherein the liquid injector changes the shape of a water film formed in the space.

14. The multi-projection system of claim 3, wherein the management device performs image correction based on differences in properties between the projection surfaces.

15. The multi-projection system of claim 14, wherein the management device corrects images so as to offset the differences in properties between the projection surfaces.

16. The multi-projection system of claim 14, wherein the management device corrects images based on chromaticity information, brightness information, reflectance information, or quality information.

17. The multi-projection system of claim 14, further comprising an imaging device for imaging the plurality of projection surfaces, wherein the management device analyzes the differences in properties between the projection surfaces using the imaging device.

18. The multi-projection system of claim 2, further comprising a light-emitting device for projecting light on the fog screen or the water screen.

19. The multi-projection system of claim 18, wherein the plurality of projection surfaces comprises a main projection surface on which a main image is projected, and wherein the light-emitting device projects light of a color associated with the main image.

20. The multi-projection system of claim 19, wherein the light-emitting device creates an appearance of a specific object associated with the main image on the fog screen or the water screen.

21. The multi-projection system of claim 18, wherein an image is projected on the fog screen or the water screen in a stage where light is projected on the fog screen or the water screen by the light-emitting device.

22. The multi-projection system of claim 21, wherein light of a color that is the same or similar to the surface color of a screen formed of a solid material is projected on the fog screen or the water screen by the light-emitting device.

23. The multi-projection system of claim 2, wherein the liquid that forms the water screen comprises particles for increasing reflectance.
