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.

Claims

1. A multi-projection system comprising:

a main projection surface on which a main image is reproduced;

an auxiliary projection surface arranged around the main projection surface,

a main projection device for projecting an image on the main projection surface;

an auxiliary projection device for projecting an image on the auxiliary projection surface; and

a management device for controlling the operation of the main projection device and the auxiliary projection device,

wherein (i) the management device recognizes visual element included in the main image and determines whether the recognized visual element correspond to a predetermined specific visual element by comparing color and pattern of the recognized visual element with those of specific visual element stored in a storage unit, and (ii) when the management device determines the recognized visual element correspond to the predetermined specific visual element, the management device extracts an auxiliary image from the main image and transmits the extracted image to the auxiliary projection device,

wherein the auxiliary projection device projects the visual element associated with the main image on the auxiliary projection surface to extend a visual effect of the image, and

wherein the management device operates the auxiliary projection device only when the predetermined specific visual element is included in the main image.

2. The multi-projection system of claim 1, wherein a visual element included in the main image is extended and displayed on the auxiliary projection surface.

3. The multi-projection system of claim 2, wherein all or part of the main image is extended and displayed on the auxiliary projection surface.

4. The multi-projection system of claim 2, wherein a specific object included in the main image is displayed on the auxiliary projection surface.

5. The multi-projection system of claim 4, wherein the specific object is displayed on the auxiliary projection surface after the size of the specific object is changed based on a vanishing point included in the main image.

6. The multi-projection system of claim 4, wherein the specific object is repeatedly displayed on the auxiliary projection surface.

7. The multi-projection system of claim 2, wherein all or part of the main image is blurred and then displayed on the auxiliary projection surface.

8. The multi-projection system of claim 1, wherein the visual element is displayed only in a partial area of the entire area of the auxiliary projection surface, which is adjacent to the main projection surface.

9. The multi-projection system of claim 1, wherein a separate image associated with the main image is displayed on the auxiliary projection surface.

10. The multi-projection system of claim 1, wherein a plurality of auxiliary projection surfaces are arranged around the main projection surface in a manner to surround an auditorium.

11. The multi-projection system of claim 10, wherein the visual element included in the main image is extended and displayed on all of the plurality of auxiliary projection surfaces or only on some of the plurality of auxiliary projection surfaces.

12. The multi-projection system of claim 1, wherein the auxiliary projection device projects a specific object recognized by the management device or the entire main image.

13. The multi-projection system of claim 1, wherein the management device performs an operation of recognizing the specific object in a specific time zone in all time zones when the main image is reproduced.

14. The multi-projection system of claim 1, wherein light having a color associated with the main image is projected on the auxiliary projection surface.

15. The multi-projection system of claim 14, wherein light of colors associated with two or more objects included in the main image is projected on the auxiliary projection surface.

16. The multi-projection system of claim 14, further comprising:

a lighting device for emitting light on the auxiliary projection surface,

wherein the management device controls the operation of the main projection device and the lighting device, and

wherein the lighting device emits light having a color associated with the main image on the auxiliary projection surface to extend a visual effect of the image.

17. The multi-projection system of claim 16, wherein the management device operates the lighting device only when the predetermined specific visual element is included in the main image.

18. The multi-projection system of claim 17, wherein the management device performs an operation of recognizing the specific visual element in a specific time zone in all time zones when the main image is reproduced.
