Multi-projection system using interior surface as projection surface

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.

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. 
     
     
         9 . (canceled) 
     
     
         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.
