Abstract: The present invention provides a “multi-projection system” including a plurality of projection surfaces arranged so as not to be parallel to each other and two or more projection devices for projecting images on the plurality of projection surfaces, in which the two or more projection devices include a refraction projection device in which projection light is refracted before it reaches a projection surface.

Abstract: The present invention provides a multi-projection system with a reflective surface, and the multi-projection system includes an image reproduction unit for visually reproducing image content and a reflective surface for reflecting an image reproduced by the image reproduction unit toward an auditorium, thus providing images to the auditorium in multiple directions.

Abstract: The present invention provides a theater structure which can be used to implement a “multi-projection system” and includes a projection equipment installed in a theater and a cover for preventing the projection equipment from being exposed to an auditorium, in which an image is projected on the surface of the cover.

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.

Abstract: The present invention provides an additional effect system and method, the additional effect system including: a plurality of projection surfaces installed in a single theater; and an additional effect device for implementing an additional effect other than images projected on the plurality of projection surfaces, wherein the additional effect device provides the additional effect depending the images projected on the plurality of projection surfaces.

Abstract: The present invention provides a multi-projection system and method including direction-changeable audience seats, and the multi-projection system includes a plurality of projection surfaces installed in a single theater; and an audience seat whose direction is changed depending on images projected on the plurality of projection surfaces.

Abstract: The present invention provides a multi-projection system for extending a visual element of a main image, the system including a main projection surface on which a main image is reproduced and an auxiliary projection surface arranged around the main projection surface, in which a visual element associated with the main image is displayed on the auxiliary projection surface.

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.

Abstract: The present invention provides a performance system with a multi-projection environment including a stage installed for a performance and a plurality of projection surfaces arranged around the stage and arranged so as not to be parallel to each other, in which synchronized images are projected on the plurality of projection surfaces.

Abstract: A multi-projection system having a plurality of projection surfaces onto which images are projected is provided, where the plurality of projection surfaces are disposed on two or more sides not parallel to each other. The multi-projection system provides high three-dimensional images and a high degree of immersion in images and further provides multi-view images, thereby making theater customers feel like they really exist in the space described through the images.
