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.

Claims

1. A theater structure comprising:

a projection equipment installed in a theater; and

a cover for preventing the projection equipment from being exposed to an auditorium,

wherein an image is projected on the surface of the cover.

2. The theater structure of claim 1, wherein the projection equipment is installed on a wall surface, a floor surface, or a ceiling surface of the theater and the cover prevents the wall surface, the floor surface, or the ceiling surface and the projection equipment from being exposed.

3. The theater structure of claim 2, wherein the projection equipment is installed on the ceiling surface and the cover comprises a dome-shaped surface.

4. The theater structure of claim 1, wherein the cover comprises an optical coating layer formed on the surface thereof.

5. The theater structure of claim 1, wherein the theater comprises a projection surface installed therein and synchronized images are projected on the surface of the cover and the projection surface.

6. The theater structure of claim 5, wherein images corrected in different ways are projected on the projection surface and the surface of the cover.

7. The theater structure of claim 6, wherein the correction is based on a difference in surface morphology, a difference in surface chromaticity, a difference in surface brightness, or a difference in surface reflectance.

8. The theater structure of claim 1, wherein the projection equipment is a projection device, the projection device projecting an image on the cover by rear projection.

9. The theater structure of claim 8, wherein the cover comprises a rear screen film for the rear projection.

10. The theater structure of claim 1, wherein the cover prevents all or part of the projection equipment from being exposed.

11. The theater structure of claim 10, wherein the cover comprises an opening for exposing part of the projection equipment.

12. The theater structure of claim 11, wherein the projection equipment is a projection device, the projection device projecting an image on the projection surface through the opening.

13. The theater structure of claim 11, wherein the opening is opened and closed by electrical control.

14. The theater structure of claim 11, wherein the projection equipment is an additional effect device, the additional effect device being exposed to the auditorium through the opening at a predetermined time.

15. The theater structure of claim 1, wherein the cover has colors in gradation formed on an outer edge thereof.

16. The theater structure of claim 15, wherein the colors in gradation are formed based on a color of the cover and a color of an adjacent projection surface.

17. A theater comprising:

a projection equipment installed in the theater; and

a cover for preventing the projection equipment from being exposed to an auditorium.

18. A multi-projection system comprising:

a projection surface on which an image is projected; and

a cover for preventing a projection equipment installed in a theater from being exposed to an auditorium,

wherein synchronized images are projected on the surface of the cover and the projection surface.

19. The multi-projection system of claim 18, wherein the cover comprises an optical coating layer formed on the surface thereof.

20. The multi-projection system of claim 18, wherein images corrected in different ways are projected on the surface of the cover and the projection surface.
