[0001] Multi-projection system and method [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system and method for projecting an image for a multi-page presentation.

Currently, a movie theater is a system that projects a two-dimensional image or a three-dimensional image by providing a large flat screen across the viewer. Three-dimensional (3D) images are intended to provide stereoscopic images to users, and many related technologies have been developed. Realization of the 3D sensation of the 3D image is realized by displaying the left eye image and the right eye image together using the user's binocular parallax. However, as 3D stereoscopic image display and fabrication technology has been developed, the production of 3D image contents has not yet been made. This is because there is still a problem to be solved such as a user's dizziness appeal during the appreciation of the three-dimensional stereoscopic image.

As an alternative to this, there is a multi-screen screening system that enables a three-dimensional image similar to a three-dimensional image to be displayed by displaying a two-dimensional image. The multi-screening system generally displays an image on a plurality of surfaces so that the user can feel the stereoscopic effect by having the user feel in the displayed image.

However, in order to implement such a multi-faceted image system in existing movie theaters, the case of a movie theater is not rectangular. However, although the image is usually produced in the form of a square with a certain size, the structure and size of the existing movie theater are different from each other and it is not appropriate to project the image produced in a uniform size as it is. Therefore, it is necessary to correct the size of the image in consideration of the structure and the size of each movie theater. However, since the image must be corrected / corrected by the number of movie theaters, time and cost are considerably uneconomical Lt; / RTI >

Accordingly, it is an object of the present invention to provide a projection system and method for a multi-screen projection capable of projecting a multi-screen image according to the structure and size of each existing movie theater.

According to the present invention, there is provided an image projection system for a multi-screen image, comprising: at least one screen provided on at least one of a plurality of surfaces to display an image; At least one image projection device for projecting an image to display an image on at least one of the plurality of surfaces and the at least one screen; A server for transmitting an image to the at least one image projection device; If the shape and size of the display region in which the image is displayed are different from the shape and size of the projection region of the image projected by the image projection apparatus, the shape and size of the projection region are adjusted to correspond to the shape and size of the display region And controlling the at least one image projection apparatus so that the image is projected only to the adjusted projection area.

The shape of the display area includes a polygon having a length of one side different from a length of the neighboring side.

The display area includes a screen provided on the left / right side wall surface or the left / right side surface based on the viewer in the movie theater.

The control unit may adjust the size of the projection area of the image using the resolution of the image projection apparatus and the resolution of the image.

The controller may adjust the resolution of the image to correspond to the resolution of the image projection apparatus if the resolution of the image is different from the resolution of the image projection apparatus.

The control unit may generate second coordinate information that uses a pixel value of the resolution of the image projection apparatus as first coordinate information and designates only an area corresponding to the display area based on the first coordinate information.

Wherein the control unit generates third coordinate information of an area matched with the second coordinate information of the first coordinate information and controls the image projection apparatus so as to project only a part of the image corresponding to the third coordinate information can do.

3A to 3C show an example of the shape of the left and right side walls of a viewer of a movie theater,
4A to 4C are explanatory diagrams of control operations of the control unit of FIG.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings, which will be readily apparent to those skilled in the art to which the present invention pertains. The present invention may be embodied in many different forms and is not limited to the embodiments described herein. In order to clearly illustrate the present invention, parts not related to the description are omitted, and the same or similar components are denoted by the same reference numerals throughout the specification.

FIG. 1 is a conceptual diagram according to an embodiment of the present invention, and FIG. 2 is a control block diagram according to an embodiment of the present invention.

1 and 2, a multi-screen projection system according to an exemplary embodiment of the present invention includes a screen 10, an image projection apparatus 20, a server 30, and a control unit 40.

The conventional movie theater has a screen on the front side based on the viewer, and when the image is projected from the projector located on the opposite side of the screen, the projected image is displayed on the screen.

The multi-screening is a system in which images are displayed by installing a screen or the like on a wall surface provided inside the movie screening tube, not only in the front but also on the left / right side or the ceiling / floor in the conventional movie theater. The advantage of multi-screening is that visitors can feel the same sense of presence as in a movie.

The screen 10 is provided on at least one of a plurality of surfaces (or wall surfaces, 1, 3, and 5) of the movie theater to display an image. 1, the screen 10 is provided on the wall surface 1 provided on the front face of the plurality of surfaces 1, 3 and 5 with respect to the viewer. However, the screen 10 is not limited to the left / Or may be provided on the ceiling (not shown) or the floor (not shown) on the head of the audience, which can be variously applied according to the design of each movie theater. The screen may be any screen as long as it is a screen for movie screening, and the surface of the plurality of surfaces (or walls) may include a sound absorbing material or an optical film-use optical coating material.

The image projection device 20 projects an image so that the image is displayed on at least one of the plurality of surfaces and the at least one screen. The image projection device 20 can project images on the screen 10 or the wall surfaces 3 and 5 on which the screen is not provided and display the images.

In addition, one image projection device 21 may project a single image onto one screen 10, or two or more image projection devices 23, 25, 27 and 29 may project a single wall 10 ) To be a single image. When two or more image projection devices 23, 25, 27 and 29 are projected so as to be a single image on one wall surface 5 (3), a single image is divided by the number of image projection devices, It can be projected to be one image.

The server (30) can transmit the image to the at least one image projection device (20). The server 30 stores the image to be displayed and transmits the image to the projection projection apparatus 20 under the control of the control unit 40. The server 30 may include movie contents or advertisement image contents, (Not shown) for a movie content and a server (not shown) for an advertisement image content according to the content of the advertisement, so that the respective images can be transmitted to one image projection device 20.

2, the server 1 31 transmits an image to one image projection apparatus 1 (21), and the server 2 (33) transmits an image to two image projection apparatuses 2, 3 (23, 25) . In the case of the server 1 (31), an image is transmitted to one image projection apparatus 1 (21) in order to display one image on one screen / one wall surface. In the case of the server 2 (33), when one image is displayed on one screen / one wall, when one screen / one wall is large or large, one image is divided, 2 (23), and the remaining part is transmitted to the image projection apparatus 3 (25) so that one image can be displayed.

If the shape and size of the display area on which the image is displayed are different from the shape and size of the projection area of the image projected by the image projection device, the control part 40 controls the shape and size of the projection area, And controls the at least one image projection apparatus so that the image is projected only to the adjusted projection area.

The shape of the display area is a polygon having a length of one side different from the length of the neighboring side, and is at least a polygon having a square or hexagonal shape, for example, a pentagon, a hexagon, a hexagon, an octagon, a pentagon, Square or more.

The shape of the display area may include a wall on the left / right side or a screen on the left / right side based on the viewer in the movie theater. Generally, the screen provided on the front side of the movie theater has a rectangular shape, but the shape of the left / right side surface is not the same. This will be described in detail with reference to FIGS. 3A to 3C, and the operation of the control unit 40 will be described in further detail with reference to FIGS. 3A to 4B. FIG.

3A to 3C illustrate the shapes of the left and right side walls around an audience of a current movie theater.

Multi-screen displays can display images on the front, left / right wall, or ceiling / floor, centered on the audience. The film is generally made in the shape of a rectangle, and a rectangular screen is usually installed on the front of the movie theater, so it is common to display the movie on the screen installed on the front.

However, in the case of the left / right side walls or the ceiling / bottom side with respect to the audience, it is almost always the case that it is not a rectangular shape. In other words, the length of one side has a polygon that is different from the length of the neighboring side, and examples of the shape of the wall are as shown in Figs. 3A to 3C, but the shape is not limited to this. In Figs. 3A to 3C, one side of (0, y1) is in contact with the side on which the screen exists, based on (0, 0). Fig. 3A shows a hexagonal shape as a shape of a most common left / right side wall surface of a movie theater, Fig. 3B shows a hexagonal shape as a shape of a left / right side wall surface of a movie theater in which a ceiling is directed toward a screen, And a shape of a left / right side wall surface in which a predetermined beam is formed on one surface contacting the ceiling surface of the movie theater.

As described above, the image corresponding to the movie is usually formed in the shape of a rectangle. As described above, the shape of the left / right side of the movie theater does not correspond to the rectangle, It was necessary to perform the second half correction work to adjust the size of the image to fit the shape of the wall. However, the problem is that since the shape of the left and right sides of the movie theater existing in the whole country is different according to the structure and the size of the building, the number of times corresponding to the number of the movie theaters, There is a problem to work with. The present invention is intended to solve such a problem.

4A to 4C illustrate an embodiment of the control operation of the control unit 40 according to an embodiment of the present invention.

An area where an image can be displayed, such as a screen 10 or a plurality of wall surfaces 1, 3, 5, is defined as a display area. An area represented by the image projected by the image projection apparatus 20 is referred to as a projection area. If the shape and size of the display region are different from the shape and size of the projection region of the image, the control unit 40 adjusts the shape and size of the projection region of the image so as to correspond to the shape and size of the display region, And controls the at least one image projection device (20) to project only to the adjusted projection area.

The control unit 40 checks the resolution of the image stored in the server and the resolution of the image projection apparatus 20 itself. The image projection apparatus 20 has an inherent resolution, and in the case of an image, has a native resolution determined by the image capturing apparatus. The control unit 40 may adjust the resolution of the image to correspond to the resolution of the image projection apparatus 20 if the resolution of the image is different from the resolution of the image projection apparatus 20. [ For example, if the resolution of the image projection apparatus 20 is 2000 x 1000px and the resolution of the image is 1500 x 800px, the image can be enlarged to 1.25 times in width and 1.25 times in length to adjust to 2025 x 1000px. That is, the resolution of the image and the resolution of the image projection apparatus are matched to each other in the same or similar manner and used to generate the first coordinate information corresponding to the projection area. 4A shows the shape and size of the projection area where the image is projected by the image projection apparatus 20 as the first coordinate information based on the resolution of the image projection apparatus 20. The reference point (0, 0) First coordinate information such as a left upper end (0, 1080), a right upper end (1920, 1080), and a right lower end (1920, 0) may be generated so as to correspond to the shape of the projection area in a clockwise direction. Coordinates included in the coordinate information are generated at all vertexes of the corresponding polygon. The reference point of the first coordinate information corresponds to the lower left end of the projection area of the image and coordinate values are designated in a clockwise direction on the basis of the reference point. The setting of the reference point can be arbitrarily set. Can be specified. The first coordinate information corresponds to a pixel value corresponding to the resolution of the image projection apparatus or a pixel value corresponding to the resolution of the image itself. This is because the control unit adjusts the resolution of the image projection apparatus and the resolution of the image itself to be the same or similar.

The control unit 40 may generate second coordinate information for specifying a region corresponding to the display area by referring to the first coordinate information of the pixel value of the resolution of the image projection apparatus. Referring to the pixel value of the resolution of the image projection apparatus, the coordinate value of the display area is shifted clockwise from the lower left reference point (0, 0) to the upper left (0, 1000) The second coordinate information can be generated by setting the middle tops 930 and 750, the right upper ends 1750 and 750, the right lower ends 1750 and 420 and the middle lower ends 0 and 500 (see FIG. 4B).

The shape and the size of the area corresponding to the first coordinate information of the projection area of FIG. 4A are different from each other in the shape and size of the area corresponding to the second coordinate information of the display area of FIG. 4B.

Therefore, the control unit 40 generates new third coordinate information having the shape and size corresponding to the shape and size of the area of the second coordinate information (Fig. 4B) of the first coordinate information area (Fig. 4A) This is the area of the hatched portion of FIG. 4C, the third coordinate information is the same as the shape and size corresponding to the second coordinate information. However, the area occupied by the third coordinate information among the areas corresponding to the first coordinate information is a coordinate value corresponding to the shape and size of the display area (second coordinate information) in the clockwise direction on the basis of the reference points 20 and 20 A scaled adjustment to an area having coordinate information such as left top 20,1020, middle top 950,770, right top 1770,770, bottom right 170,420, middle bottom 20,520, Images can be generated.

If the size of the projection area is smaller than the display area, the controller 40 may extend the image up, down, left, and right so that the size of the projection area has a size corresponding to the display area.

Therefore, according to the present invention, the structure, shape, and size of the movie theater are measured in advance, and the coordinate information is generated using the resolution of the image projection apparatus. The size of the projection area projected by the image projection apparatus . Thereby, it is possible to display only the image having the shape and size corresponding to the display area through the control unit simply by using the coordinate information without performing the post-adjustment operation of the size of the image separately for each movie theater, Since only the device is adjusted, the adjustment operation for the image does not need to be carried out, and it is possible to enjoy favorable economic effects due to time, cost, maintenance, and the like.

The method includes the steps of measuring a shape and a size of a display area (S100), confirming a shape and size of a projection area in which an image is projected (S200) (S300) of comparing the shape and size of the measured display area with the shape and size of the projection area, and if the comparison result is the same, transmitting the image to the image projection apparatus (S500) And adjusting the shape and the size of the projection area so as to correspond to the shape and size of the display limited area when they are different from each other (S400).
