Abstract

The present invention provides a multi-projection system using an interior surface as a projection surface, the system including a screen installed in a single theater, a plurality of interior surfaces arranged around the screen, and two or more projection devices for projecting synchronized images on the screen and the interior surfaces.

Claims

1. A multi-projection system comprising:

a screen installed in a single theater;

a plurality of interior surfaces arranged around the screen; and

two or more projection devices for projecting synchronized images on the screen and the interior surfaces.

2. The multi-projection system of claim 1, wherein the interior surface is a wall surface, a floor surface, or a ceiling surface.

3. The multi-projection system of claim 1, wherein the interior surface comprises a coating layer for improving optical properties.

4. The multi-projection system of claim 3, wherein the coating layer improves polarization properties, scattering properties, or reflectance properties of the interior surface.

5. The multi-projection system of claim 3, wherein the coating layer is formed by applying a paint for improving optical properties on the interior surface.

6. The multi-projection system of claim 5, wherein the paint comprises:

optical particles for improving optical properties; and

a fluid serving as a carrier for the optical particles.

7. The multi-projection system of claim 6, wherein the optical particles are formed by cutting or pulverizing an optical substrate including a metal layer or a dielectric layer.

8. The multi-projection system of claim 3, wherein the interior surface comprises a sound insulating member layer, and the coating layer is formed on the sound insulating member layer.

10. The multi-projection system of claim 3, wherein the coating layer comprises a color area displayed in gradation around the boundary between the screen and the interior surface.

11. The multi-projection system of claim 1, further comprising a management device for controlling the operation of the two or more projection devices.

12. The multi-projection system of claim 11, wherein the management device corrects the images projected by the two or more projection devices and then transmits the corrected images to the two or more projection devices.

13. The multi-projection system of claim 12, wherein the management device corrects the images projected by the two or more projection devices so as to offset relative differences in properties between the screen and the interior surfaces.
