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.

Claims

1. A multi-projection system comprising:

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,

wherein the multi-projection system provides images to the auditorium in multiple directions.

2. The multi-projection system of claim 1, comprising a plurality of image reproduction units,

wherein the plurality of image reproduction units and the reflective surface are arranged around the auditorium.

3. The multi-projection system of claim 1, comprising a plurality of reflective surfaces,

wherein the image reproduction unit and the plurality of reflective surfaces are arranged around the auditorium.

4. The multi-projection system of claim 1, comprising a plurality of image reproduction units and a plurality of reflective surfaces,

wherein the plurality of image reproduction units and the plurality of reflective surfaces are arranged around the auditorium.

5. The multi-projection system of claim 1, wherein the image reproduction unit is a display device.

6. The multi-projection system of claim 1, wherein the image reproduction unit comprises a projection surface on which an image is projected by a projection device.

7. The multi-projection system of claim 1, wherein the reflective surface is arranged to face the image reproduction unit and the auditorium.

8. The multi-projection system of claim 7, wherein the reflective surface is provided in the form of a flat surface or a curved surface.

9. The multi-projection system of claim 8, wherein the reflective surface and the image reproduction unit are provided in the form of a flat surface and arranged in parallel to each other or arranged at an acute angle to each other.

10. The multi-projection system of claim 1, further comprising:

a reflective surface blocking unit for blocking external exposure of the reflective surface; and

a management device for controlling the operation of the reflective surface blocking unit.

11. The multi-projection system of claim 10, wherein the reflective surface blocking unit changes an area, in which the reflective surface is exposed to the outside, under the control of the management device.

12. The multi-projection system of claim 10, wherein the reflective surface blocking unit comprises two or more partial reflective surface blocking units, each partial reflective surface blocking unit blocking a partial region of the reflective surface.

13. The multi-projection system of claim 12, wherein the management device independently controls the two or more partial reflective surface blocking units.

14. The multi-projection system of claim 10, wherein the management device comprises control information of the reflective surface blocking unit, the control information containing operation time information and exposure area information.

15. The multi-projection system of claim 14, wherein the operation time information is generated based on time code information of the image content reproduced by the image reproduction unit.

16. The multi-projection system of claim 1, wherein the reflective surface has a reflectance that is changed by applied voltage.

17. The multi-projection system of claim 16, further comprising a management device for controlling the voltage applied to the reflective surface, the management device controlling the reflectance of the reflective surface by controlling the voltage applied to the reflective surface.

18. The multi-projection system of claim 16, wherein the reflective surface comprises two or more partial reflective surfaces and the management device independently controls the voltage applied to the two or more partial reflective surfaces.

19. The multi-projection system of claim 10, wherein when a reflected image is exposed through the reflective surface, the management device implements an additional effect depending on the reflected image and changes the additional effect depending on the formation direction of the reflective surface.

20. A multi-projection method comprising the steps of:

(a) visually reproducing, at an image reproduction unit, image content;

(b) reflecting, at a reflective surface, an image reproduced by the image reproduction unit; and

(c) allowing the image reflected by the reflective surface to be provided to an auditorium,

wherein the multi-projection method provides images to the auditorium in multiple directions.
