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 front screen arranged in front of an auditorium;

a first plurality of screens arranged from the left side of the front screen; and

a second plurality of screens arranged from the right side of the front screen,

wherein the first plurality of the screens is spaced apart from each other, and

wherein the second plurality of the screens is spaced apart from each other

wherein the first plurality of the screens are parallel to each other and arranged to have a predetermined angle from the front screen.

2. The multi-projection system of claim 1, wherein

the front screen comprises a different material from materials of the first and second plurality of screens.

3. The multi-projection system of claim 1,

wherein the first plurality of screens or the second plurality of screens comprises a Light-Emitting Diode Display (LED) or Liquid Crystal Display (LCD).
