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.

Claims

1. An additional effect system, comprising:

a plurality of projection surfaces installed in a single theater;

an image management device configured to correct images to be projected by a plurality of projection devices on the plurality of projection surfaces, wherein the images projected on the plurality of projection surfaces are synchronized with each other;

a plurality of additional effect devices configured to implement an additional effect other than the images projected on the plurality of projection surfaces; and

an additional effect management device configured to control the plurality of additional effect devices,

wherein the additional effect includes wind, smell, temperature change, water jet, vibration, or bubbles,

wherein the plurality of additional effect devices is configured to, depending on the images projected on the plurality of projection surfaces,

provide the additional effect, and

selectively change a direction of the additional effect,

wherein when a specific event in one of the images occurs only on a specific projection surface among the plurality of projection surfaces, the plurality of additional effect devices is configured to implement the additional effect only in a direction that starts from the specific projection surface, and

wherein the image management device is configured to correct the images so as to offset a difference in brightness, color or material of the plurality of projection surfaces.

2. The additional effect system of claim 1, wherein the plurality of additional effect devices is configured to change the direction of the additional effect depending on the images projected on the plurality of projection surfaces.

3. The additional effect system of claim 2, wherein when an object in one of the images moves between the plurality of projection surfaces, the plurality of additional effect devices is configured to change the direction of the additional effect depending on a movement direction of the object.

4. The additional effect system of claim 2, wherein when an environment in one of the images changes between the plurality of projection surfaces, the plurality of additional effect devices is configured to change a configuration of the direction of the additional effect.

5. The additional effect system of claim 1,

wherein the additional effect management device is configured to transmit a control signal to the plurality of additional effect devices, and

wherein the control signal includes time information and operation information.

6. The additional effect system of claim 5, wherein the plurality of additional effect devices is synchronized with each other -and with the images, projected on the plurality of projection surfaces, based on the time information.

7. The additional effect system of claim 1,

wherein the additional effect is wind and the plurality of additional effect devices comprises a plurality of air blowers,

wherein the plurality of air blowers is distributed in the single theater, and

wherein the additional effect system is configured to change a direction of the wind through the two or more air blowers.

8. The additional effect system of claim 7, wherein when an object in one of the images moves between the plurality of projection surfaces, the additional effect system is configured to change a direction of the wind through the plurality of air blowers.

9. The additional effect system of claim 7, wherein when an environment in one of the images changes between the plurality of projection surfaces, the additional effect system is configured to change a direction of the wind through the plurality of air blowers.

10. The additional effect system of claim 1,

wherein the additional effect is vibration and the plurality of additional effect devices comprises a plurality of vibration devices, and

wherein the plurality of vibration devices is distributed on a floor of the single theater.

11. The additional effect system of claim 10, wherein the plurality of vibration devices is configured to implement a directionality of the vibration by a sequential operation.

12. The additional effect system of claim 10, wherein, when an object in one of the images moves between the plurality of projection surfaces, the additional effect system is configured to change the direction of the vibration through the plurality of vibration devices.

15. The additional effect system of claim 1, wherein the additional effect is smell.

13. A non-transitory recording medium readable by an electronic device, in which a method for implementing an additional effect is record as a program, the method comprising:

(a) causing multi-projection images to be projected on a plurality of projection surfaces installed in a single theater by a plurality of projection devices wherein the images projected on the plurality of projection surfaces are synchronized with each other; and

(b) causing an additional effect other than the images to be implemented by a plurality of additional effect devices, wherein the additional effect includes wind, smell, temperature change, water jet, vibration, or bubbles, and

wherein the plurality of additional effect devices provides the additional effect depending on the multi-projection images projected on the plurality of projection surfaces, and the plurality of additional effect devices selectively changes the direction of the additional effect,

wherein when a specific event in one of the images occurs only on a specific projection surface among the plurality of projection surfaces, the plurality of additional effect devices is configured to implement the additional effect only in a direction that starts from the specific projection surface, and

wherein the multi-projection images are corrected so as to offset a difference in brightness, color or material of the plurality of projection surfaces.

14. An additional effect method for multi-projection, the method comprising:

projecting, by a plurality of projection devices, a plurality of images on a plurality of projection surfaces installed in a single theater wherein the images projected on the plurality of projection surfaces are synchronized with each other;

implementing, by a plurality of additional effect devices, an additional effect other than the images wherein the additional effect includes wind, smell, temperature change, water jet, vibration, or bubbles; and

controlling, by an additional effect management device, the additional effect depending on the images projected on the plurality of the projection surfaces,

wherein a direction of the additional effect is selectively changed based on the images,

wherein when a specific event in one of the images occurs only on a specific projection surface among the plurality of projection surfaces, the plurality of additional effect devices is configured to implement the additional effect only in a direction that starts from the specific projection surface, and

wherein the images to be projected on the plurality of projection surfaces are corrected so as to offset a difference in brightness, color or material of the plurality of projection surfaces.
