Description

TECHNICAL FIELD [0001] The present invention relates to a structure of a movie theater and a screening system using the same,

[0001] The present invention relates to an auditorium structure and a multi-screen display system using the same, and more particularly, to a multi-screen display system that can prevent a screening apparatus (e.g., a speaker, a projection device, a frame structure, etc.) from being exposed in a viewer's seat, Can be projected so that it can be utilized in the implementation of a 'multi-screen screening system'.

Conventionally, a two-dimensional image is projected on a single screen disposed in front of an auditorium to reproduce images such as movies and advertisements in a theater. However, under such a system, the audience was forced to view only 2D (2D) images.

In recent years, 3D image technology has been developed that can provide stereoscopic images to the audience. 3D image technology is a technology that allows a user to feel stereoscopic effects in a plane image when different images are entered into the left eye and right eye of a person, The principle is to use two cameras equipped with different polarizing filters at the time of image capturing and to use glasses equipped with a polarizing filter at the time of viewing the images so that different images can be entered into the left eye and the right eye.

However, such a 3D technology can provide a stereoscopic image to a user, but still has a limitation in that the image itself is less immersive because it is merely viewing an image reproduced on a single screen. Also, there was a limitation that the direction of stereoscopic feeling that the audience perceives is limited to the direction in which a single screen exists.

In addition, the conventional 3D technology is inconvenient to viewers because it is necessary to wear glasses or the like equipped with a polarizing filter at the time of watching the video, Sensitive audiences could feel dizziness or loudness.

Accordingly, a so-called 'multiple screening system' has been proposed which can solve the problems of the conventional screening system based on a single screen. The 'multi-screening system' is a system in which a plurality of projection surfaces are arranged around a viewer's seat, Means a technique capable of projecting an image synchronized on the surface to provide stereoscopic effect and immersion feeling to the audience.

On the other hand, in order to implement such a multi-screen display system, a plurality of projection planes are essential. Therefore, in order to construct such a multi-screen display system in a conventional screen including only a single screen (conventional screen), it is necessary to provide an additional screen in the screen.

However, adding a "traditional white or silver screen" inside the already-completed auditorium is not an easy task and requires a lot of work. In addition, in some specific auditoriums, additional installation of screens may not be possible due to the nature of the internal structure.

In addition, even if the 'structural surface (wall surface, floor surface, ceiling scene, etc.) itself of the auditorium' is utilized as a projection surface without installing additional screens, a normal projection surface due to a plurality of screening equipment installed on the surface of the structural surface It can not be implemented. (Because the screening apparatus is provided with various screening apparatuses as shown in FIG. 1, when the screening surface of the screening apparatus itself is used as a projection plane, only the images severely distorted by the external appearance of the screening apparatus are implemented.

Accordingly, it is possible to implement 'multiple projection planes' for multi-screening without installing a conventional screen in the inside of the auditorium, and even when various screening equipment is installed on the surface of the structure plane, A new technology capable of realizing a plurality of projection surfaces is required.

The present invention has been made to solve the above problems, and it is an object of the present invention to solve the above-mentioned problems and to provide additional technical elements that can not be readily invented by those skilled in the art.

Hereinafter, an auditorium structure according to embodiments of the present invention and a multi-screen display system using the same will be described in detail with reference to the accompanying drawings. The embodiments are provided so that those skilled in the art can easily understand the technical spirit of the present invention, and thus the present invention is not limited thereto. In addition, the matters described in the attached drawings may be different from those actually implemented by the schematic drawings to easily describe the embodiments of the present invention.

In the meantime, each constituent unit described below is only an example for implementing the present invention. Thus, in other implementations of the present invention, other components may be used without departing from the spirit and scope of the present invention. In addition, each component may be implemented solely by hardware or software configuration, but may be implemented by a combination of various hardware and software configurations performing the same function.

Also, the expression " comprising " is intended to merely denote the presence of that element as an " open representation ", and should not be construed as excluding additional elements.

Also, terms including ordinals such as 'first, second, third', etc. may be used to describe various components, but they are used only for the purpose of distinguishing one component from another And the attributes of the components are not limited by the terms.

It is to be understood that when an element is referred to as being "connected" or "connected" to another element, it may be directly connected / connected to the other element, but it should be understood that other intermediate elements may exist do.

As used herein, the term " structural surface " refers to surfaces that form the internal structure of an auditorium. The 'structural surface' may include various surfaces such as a ceiling surface, a bottom surface, and a wall surface formed inside the screening tube.

Also, the term 'conventional screen' as used herein means a white screen, an off-white screen, a silver screen, or the like, which is mainly installed in a conventional screen.

The term 'other projection surface' used herein is a term that refers to all projection surfaces except the projection surface (the surface of the cover to be discussed later), which can be formed by the display tube structure according to the present invention. Accordingly, the 'other projection surface' may include various projection surfaces such as a conventional screen, a wall surface, and the like.

Hereinafter, an auditorium structure according to an embodiment of the present invention will be described with reference to FIGS. 2 to 4. FIG.

Referring to FIG. 2, the screening structure according to an embodiment of the present invention includes a screening apparatus 200 installed inside an auditorium, and a cover 100 for blocking exposure of the screening apparatus in a viewer's seat direction And the surface of the cover 100 can be utilized as a projection surface on which an image is projected.

The screening equipment 200 refers to various equipment installed inside the screening hall for screening itself or for assisting screening.

Such a screening apparatus 200 may include a projector, a sound device (speaker, etc.), a light emitting device, a blower, a perfume sprayer, a fog machine, a heater, a cooler, a laser device, A frame structure in which the apparatus is installed, and an inner skeletal structure of the auditorium. Various other equipment that may be formed on the structure of the auditorium may be included in addition to these examples.

On the other hand, since conventional screening apparatuses are installed on the structural surfaces (left side, right side, rear side, bottom side, ceiling side, etc.) other than the front side where the 'traditional screen' is installed, Screen 'was difficult to install. In addition, even when the structural surface itself is used as a projection surface, a normal projection surface can not be realized due to image distortion caused by the screening equipment installed on the surface (physical appearance of screening equipment).

The present invention is characterized in that the conventional screen is provided with a cover 100 capable of blocking external exposures of screening equipment and the surface of the cover 100 itself is used as a projection surface, A smooth projection surface (with less image distortion) can be formed without changing the installation position of the screening equipment.

The cover 100 is configured to block exposure of the screening equipment in the direction of the audience seat, as has been briefly seen from above. Specifically, the cover 100 is formed between a screening equipment installed on a structural surface (a wall surface, a ceiling surface, a floor surface, and the like) and a viewer seat so as to prevent exposure of the structural surface or screening equipment in the direction of the viewer's seat .

The cover 100 preferably includes a surface having irregularities because it can serve as a smooth projection surface (projection surface with less image distortion) based on the irregular surface. Therefore, the cover 100 can smoothly reproduce images projected by the projection device for cover 150 using the uneven surface in a state in which exposure of the screening equipment 200 and the structural surface is blocked, , So that additional images can be provided to the audience through these operations. The direction in which the image is projected on the surface of the cover 100 may be variously configured. For example, an image may be projected from the outside of the cover 100 to the outer surface of the cover 100 (in the embodiment of FIG. 2) or inside the cover 100 The image may be projected (not shown) on the surface.

In addition, the cover 100 may be formed in the form of a lid having a space formed therein, and may be formed in a detachable form on the structural plane of the movie theater. Therefore, the cover 100 can accommodate the screening equipment by using the space, and even when additional installation of the equipment is required, the equipment can be additionally accommodated through the detachment operation of the cover 100 have.

In addition, the cover 100 may include various types of surfaces. Specifically, the cover 100 may include various types of surfaces such as a dome shape, a polygonal shape, and a circular shape. The shape of the cover may be variously formed according to characteristics of a content (movie, advertisement, etc.) to be displayed or characteristics of an auditorium, and may be applied to an auditorium.

In addition, the cover 100 may include a surface on which an optical coating layer is formed, as will be described later. Therefore, a high-quality projection surface can be realized through the surface on which the optical coating layer is formed, and a sense of heterogeneity that may occur between the projection surfaces can be reduced.

Also, the cover 100 may include a color of a gradation type, as will be described later. Specifically, a hue of gradation type may be formed on the outer portion of the cover 100. Even if the hue of the cover 100 is different from the hue of the adjacent projection surface through the hue of the gradation type, It is possible to alleviate the sense of heterogeneity in the vicinity.

Further, the cover 100 may further include openings, as will be described later. Therefore, the operation of the screening equipment 200 accommodated in the inside of the cover can be transmitted to the outside of the cover 100 through the opening. For example, a projection device accommodated in the cover 100 may project an image onto a projection surface disposed outside through the opening, or an additional effect device accommodated in the cover may have an additional effect , Aroma, water spray, wind, etc.) to the outside.

The cover 100 may further include an opening that can be opened and closed by an electrical control, as will be described later. Therefore, through such a configuration, it is possible to implement a closed surface on which an image can be smoothly projected, and selectively open and close the opening portion as necessary to transmit the operation of the screening apparatus to the outside.

Further, on the surface of the cover 100, a synchronized image can be projected, as will be seen from the rear. Specifically, an image synchronized with an image projected on a projection surface provided on an auditorium may be projected onto the surface of the cover 100. [ Accordingly, the surface of the cover 100 can realize a multi-screen display environment together with a projection surface provided in an auditorium, and can provide a multi-view image that is synchronized and unified to the audience.

Also, on the surface of the cover 100, a corrected image may be projected, as will be seen from the rear. Here, the correction may be a correction considering the surface, color, chromaticity, brightness, reflectance, material, and the like. In addition, the correction may be a correction considering a property difference between the 'surface of the cover 100' and the projection surface provided in the image tube. Specifically, the correction may be a correction for canceling a property difference (color difference, chromaticity difference, brightness difference, reflectance difference, shape difference, material difference, etc.) between the surface of the cover and the projection surface.

Referring to FIG. 3, the display tube structure according to an embodiment of the present invention may include a cover 100 formed in a dome shape in particular.

Specifically, in one embodiment of the present invention, the display tube structure may include a cover 100 formed on a structural surface such as a ceiling surface, a floor surface, a wall surface, etc., And a surface formed in a dome shape as shown in FIG.

Accordingly, the display tube structure according to the embodiment of the present invention can surround the viewer's seat even through the dome shape itself, and in this state, the image can be projected onto the dome-shaped surface (the surface of the cover 100) It is possible to maximize the immersion feeling that the audience feels. (This is because the audience is more likely to feel that they are surrounded by images.)

Particularly, when a multi-screen display system is implemented using the surface of the dome-shaped cover 100, the audience can be primarily surrounded by a plurality of projection surfaces, Can be secondarily surrounded by the dome shape, so that the three-dimensional feeling and the feeling of immersion felt by the audience can be further maximized.

Referring to FIG. 4, an optical coating layer 110 may be formed on a surface of the cover 100 according to an embodiment of the present invention.

In particular, the display tube structure according to an embodiment of the present invention may include an optical coating layer 110 on the surface of the cover 100, and a high quality Can be realized. Accordingly, the display tube structure according to an embodiment of the present invention can realize image quality similar to that of other projection surfaces installed in an auditorium through the optical coating layer 110, It is possible to reduce a sense of heterogeneity that may occur between images.

The optical coating layer 110 is a structure for improving the optical properties of the surface of the cover 100. The optical coating layer 110 may be formed by changing the surface of the cover 100 to a smooth shape (uneven shape) or by changing the surface material of the cover 100 to optical characteristics (polarization characteristic, reflectance characteristic, scattering characteristic Etc.) can be changed to excellent materials.

Meanwhile, the method of forming the optical coating layer 110 may be performed by various methods, typically, by coating an optical coating. Specifically, the optical coating layer 110 may be formed by applying an optical coating material capable of improving optical characteristics to the surface of the cover 100. The optical coating material may include various kinds or materials of various states. For example, the optical coating material may include a sculptured particle for improving optical properties and a fluid acting as a carrier of the sculptured particle. .

The engraved particles mean particles included in the optical coating layer 110 to improve optical characteristics. Such sculptured particles may include various fine particles for improving optical properties, for example, metal particles (e.g., aluminum) having excellent reflection characteristics, dielectric particles having excellent optical properties (e.g., silicon oxide particles, fluorinated Magnesium particles) and the like. Meanwhile, the engraved particles may be formed by cutting or grinding an optical substrate including a metal layer (for example, an aluminum layer or the like) or a dielectric layer (for example, a silicon oxide layer or the like). That is, the engraved particles can be formed by deforming an optical substrate on which a metal layer or a dielectric layer is formed, into small particles through a physical method.

In addition, the fluid is a structure that serves as a carrier to enable the particles to be coated. Such a fluid may be composed of various flow materials, and is preferably composed of a material such as PVC resin, enamel, polyurethane, acrylic resin, lacquer, or the like .

Hereinafter, referring to FIG. 5, an example in which an opening is formed in an auditorium structure according to an embodiment of the present invention will be described.

Referring to FIG. 5, the cover 100 may be configured to include an opening 120 exposing a part of the screening equipment accommodated therein.

Accordingly, through the opening 120, the operation of the screening equipment 200 housed in the cover 100 may be transmitted to the outside. 5, when the projection device 220 or the light emitting device 230 is accommodated in the cover 100, the image projected by the projection device 220 through the opening 120, The light projected by the light emitting device 230 can be transmitted to the outside.

In this case, the opening 120 is preferably formed in a minimized size. Specifically, it is preferable that the display apparatus 200 is formed to have a size that exposes only the minimum configuration necessary for transmitting the operation of the screening apparatus 200 to the outside. It is necessary to minimize the size of the opening 120 since the image may be distorted by the opening 120 (the physical shape of the opening) when the surface of the cover 100 is used as a projection surface. Therefore, it is preferable that the opening 120 is formed in a minimized form such as a size for exposing only the lamp of the projection device 220 to the outside, a size for exposing only the lamp of the light emitting device 230, and the like.

5, the display tube structure according to an embodiment of the present invention may include a cover 100 that accommodates a screening device 220, a display device 200 such as a light emitting device 230, The cover 100 is formed with an opening 120 for exposing the lamp of the projection device 220 or the lamp of the light emitting device 230 to the outside. In addition, the opening 120 is formed in a minimized size such that only the lamp of the projection device 220 or the lamp of the light emitting device 230 is exposed to the outside.

5, even when the image is projected on the surface of the cover 100, the projection device 220 housed in the cover 100 may project the image on the 'other projection surface' It can be projected. 5, a projection device 220 accommodated in the cover 100 is projected onto the surface of the other cover, and the projected image is projected onto the surface of the other cover when the other cover is disposed around the cover 100. [ .

If the opening 120 is formed in the cover 100, the image 120 may be distorted due to the presence of the opening 120, even if the opening 120 is formed in a minimized size. Accordingly, the present invention may be configured such that the corrected image is projected on the surface of the cover 100 including the opening 120. Specifically, the present invention can correct the image in a direction that cancels the distortion caused by the opening 120 after analyzing the distortion information caused by the opening 120. For example, according to the present invention, the opening 120 may analyze information for distorting the color of an image to correct an image, or may analyze information that the opening 120 distorts the geometry of the surface, can do. Also, the present invention may correct the image by analyzing information such as brightness difference and reflectance difference caused by the opening 120.

Such a correction operation can be performed by various apparatuses including a management apparatus to be discussed later.

Hereinafter, with reference to FIG. 6, an example in which an opening capable of opening and closing is formed in an auditorium structure according to an embodiment of the present invention will be described.

The display tube structure according to an embodiment of the present invention may include an opening 120 that can be opened and closed. Specifically, the structure according to an embodiment of the present invention can be opened when it is necessary to transmit the operation of the screening equipment 200 housed inside the cover 100 to the outside, The opening 120 may be closed when it is not necessary to transmit the light to the outside. Accordingly, the time during which the screening equipment 200 is exposed to the outside can be minimized through the openable / closable opening 120, and the surface of the cover 100 maximizes the time for implementing the smoothest projection surface .

The opening 120 may selectively expose various screening equipment 200 to the outside. Specifically, the opening 120 may be selectively activated only at a specific point in time by the projection device 220, the light emitting device 230, the additional effect device 240 and the like accommodated in the cover 100 through the opening / .

Meanwhile, the display tube structure according to an embodiment of the present invention may accommodate an additional effect device 240 that can move inside the cover 100. Specifically, the display tube structure includes an additional effect device 240 installed in a movable form (for example, fixed in a frame capable of being linear or rotatable and able to move by the motion of the frame) as shown in FIG. 6 can do. Accordingly, in this embodiment, when the opening 120 is opened, the additional effect device 240 is completely exposed to the viewer's seat through the movement, and when the opening 120 is closed The additional effect device 240 can be fully accommodated into the cover 100 through movement.

For reference, the additional effect device 240 may be realized by various screening devices as an apparatus for implementing additional effects other than images. For example, the additional effect device 240 may be configured to expose a structure that matches a reproduced image to a field of view of an audience (e.g., expose a planetary structure to a viewer's field when a planet- (A structure) of the airplane when the scene in which the airplane falls is reproduced is exposed to the field of view of the audience). In addition to these devices, a speaker, a blower, an aroma injector, a fog machine, a light emitting device, a radiator, , A soap drop generator, an LED, and a water injection device, which can stimulate the human senses.

Meanwhile, the opening and closing operations of the opening 120 and the operation (motion) of the additional effect device 240 can be controlled by various devices including a management apparatus to be discussed later. In this case, the opening and closing operations of the opening 120 and the operation of the additional effect device 240 can be controlled in a form associated with an image projected on the surface of the cover 100 or an image projected on another projection surface . For example, the opening / closing operation of the opening 120 and the operation of the additional effect device 240 can be controlled based on the time code of the image data projected on the surface of the cover 100 or another projection surface , And may be controlled to operate at a specific time point on the time code.

In the present invention, a multi-screen screening system can be constructed using the screening tube structure.

First, the present invention can implement a 'multi-screen display system' by using a plurality of 'different projection planes 300' installed in an auditorium and the surface of the cover 100 together. For example, as shown in FIG. 7, another projection surface 300 is disposed on the front surface, the left surface, the right surface, and the bottom surface, and the cover 100 is disposed on the ceiling, A 'multi-screen display system' in which an image is reproduced from an upper side (a ceiling scene) can be implemented. (For reference, the reason why the ceiling surface of the ceiling is implemented by the cover 100 in the embodiment of FIG. 7 is that, generally, various screening equipments are installed in the ceiling of the auditorium so that a projection surface having a smooth surface is implemented It is difficult to do.)

In addition, when the screening equipment is complicatedly installed on the floor, the left side, the right side, the front side or the rear side as well as the ceiling, the present invention can be applied to the floor, left side, right side, The cover 100 may be installed instead of the projection surface 300 '. Therefore, in this embodiment, two or more of the plurality of projection surfaces for realizing the multi-screen presentation can be implemented using the cover.

Further, the present invention can be implemented by using the cover 100 for all the projection surfaces for implementing the multi-screen display system. For example, the cover 100 may be formed on both the front side, the left side, the right side, the ceiling, and the bottom surface of the auditorium, and a plurality of covers may be used to implement all of the plurality of projection surfaces.

Meanwhile, as mentioned briefly above, the 'other projection plane 300' may include various projection planes other than the projection plane implemented using the surface of the cover 100. Specifically, the 'other projection surface 300' may include various projection surfaces on which images such as 'screen' and 'structural surface' can be projected.

Here, the 'screen' is a structure for allowing a viewer to view an image by reflecting an image projected by a projector or the like, and may be formed in various types within a range capable of performing such a function.

For example, the screen may be a PVC screen, a white coated PVC screen, a pearl gloss coated PVC screen, an aluminum coated PVC screen, a matte screen, a lenticular screen, a glass beaded screen, a silver screen, a high-gain screen, and the like. Further, the screen may be formed of various types of screens such as an electric embedded screen, a motorized exposure screen, a wall-mounted screen, a triangular large screen, a road warrior screen, a high luminance screen, a sound screen and the like. In addition, the screen may be formed of a screen such as a water screen, a fog screen, a holographic screen, a miracle screen (a screen using magic glass), or the like.

On the other hand, the screen may be formed of an object not belonging to the category of the 'conventional screen' or an object other than the screen itself. (That is, if the specific name of the specific object itself is not a screen, the object may be included in the category of the screen if the surface of the specific object can serve as an image projection surface.) For example, If objects such as panels and curtains are installed in the interior and a surface image of the object can be projected, the objects may be included in the category of the screen regardless of the proper name.

Also, the 'structural surface' means a structural surface formed in the inside of the auditorium, as mentioned above, and includes a ceiling surface, a bottom surface, a wall surface (a wall surface of a front surface, a wall surface of a left surface, Etc.) may be included.

On the other hand, the present invention can project images synchronized with each other on a plurality of projection surfaces after constructing the multi-display screening system. Accordingly, the present invention projects a synchronized image on a plurality of projection surfaces arranged in a manner surrounding an audience, so that the audience can feel the feeling that they are actually on the scene depicted by the image.

In addition, the present invention can project images that are differently corrected on a plurality of projection surfaces after the multi-display screening system is constructed. Specifically, the present invention is characterized in that the cover 100 is configured such that when a part of a plurality of projection surfaces is implemented using the cover 100 and the remainder is implemented using the 'other projection surface 300' The image projected on the surface of the cover 100 and the other projection surface 300 are formed in consideration of the difference in properties (color, chromaticity, brightness, shape, reflectance, etc.) 'Can be corrected differently. If images of the same corrected image are projected in a state where the surface of the cover 100 and the 'other projection surface 300' have different properties, images reproduced on both projection surfaces may cause a sense of heterogeneity , So that the sense of immersion of the audience may be deteriorated. 2) In the case where two or more covers 100 having different properties are included in the plurality of projection surfaces, the present invention may be configured such that images that are differently corrected are projected on the surfaces of the two or more covers 100 . 3) Also, in the case where two or more 'different projection planes 300' having different properties are included in the plurality of projection planes, the present invention may be modified such that the two or more 'different projection planes 300' So that the image can be projected.

As a result, in the case of constructing a multi-screen display system using a plurality of projection surfaces having different properties, the present invention can project images that are differently corrected on the plurality of projection surfaces.

Here, the correction may be a correction in consideration of the difference in shape of the surface. That is, the plurality of projection planes may be projected with differently corrected images (differently corrected images to cancel the shape difference of the surface) in consideration of the shape difference of the surface.

In addition, the correction may be a correction in consideration of color or chromaticity difference. That is, the plurality of projection planes may be projected with differently corrected images (differently corrected images for canceling color or chromaticity difference of the surface) in consideration of the color or chromaticity difference of the surface.

In addition, the correction may be a correction considering the brightness difference. That is, images that are differently corrected in consideration of the difference in brightness of the surface may be projected on the plurality of projection surfaces (images corrected differently to compensate for brightness difference of the surface).

Further, the correction may be a correction considering the reflectance difference. That is, the images corrected differently in consideration of the difference in reflectance may be projected on the plurality of projection surfaces (images corrected differently to compensate for the reflectance difference).

In addition, the correction may be a correction that takes into account differences in various characteristics in addition to the above-mentioned features.

Meanwhile, the process of correcting the images projected on the plurality of projection surfaces differently from each other in consideration of the difference in the properties of the plurality of projection surfaces may reduce the difference in properties between the projection surfaces, Direction ".

Typically, the correction considering the chromaticity difference information of the plurality of projection surfaces (the processes to be discussed below can be applied by analogy to the correction considering the color difference, the brightness difference, the reflectance difference, the shape difference, etc.) Chromaticity difference information between the projection planes can be calculated in consideration of chromaticity information of the projection planes. Specifically, after setting one reference projection plane, relative chromaticity difference information of each projection plane can be calculated. For example, the "A projection surface has a chromaticity level of R (red) of 50 levels higher than that of the reference projection surface, a chromaticity level of G (green) of 40 levels higher, and a chromaticity level of B And calculates relative chromaticity difference information in the same manner. For example, when the chromaticity of the image projected on the A projection surface is lowered by 50 levels, and G is 40, the chromaticity of the image projected on the A projection surface is lowered by 50. Thus, Level is lowered, and the level of B is maintained ". Therefore, the chromaticity difference of the projection surfaces can be canceled by such a process.

Meanwhile, the analysis of the property difference of the plurality of projection surfaces can be variously performed by a method other than the setting of the reference projection surface. For example, after calculating the representative values (average value, median value, mode value, and the like) regarding the properties of the plurality of projection surfaces, it is possible to analyze the relative characteristic difference based on the calculated representative value.

Meanwhile, the multi-display screening system according to an embodiment of the present invention may include a cover 100 having a color of a gradation type formed on an outer periphery thereof. Here, the hue of the gradation type is preferably formed based on the hue of the projection surface adjacent to the hue of the cover 100. For example, when the color of the cover 100 is black and the color of the neighboring projection surface is white, the gradation color preferably represents a change in color between black and white.

Accordingly, the present invention is based on the use of such gradation-type hues, in the case where the surface of the cover 100 and the 'other projection surface 300' have surfaces of different colors, It can alleviate heterogeneity. In addition, the present invention is characterized in that the multi-screening system includes two or more covers 100 arranged adjacent to each other, and even when the two or more covers 100 are of different colors, It is possible to alleviate the sense of heterogeneity that can be caused at the boundaries of the two.

Referring to FIG. 8, a concrete example of such an embodiment can be seen. 8, the 'other projection surface 300' is disposed on the front, left, and right sides, and the cover 100 is disposed on the ceiling. The 'other projection surface 300' The surface of the light guide plate 100 is formed in different colors, and a sudden sense of heterogeneity can be caused near the boundary of the projection surfaces. However, according to the present invention, a gradation hue is formed on the outer periphery of the cover 100 to prevent a sudden unevenness that may occur near the boundary.

Meanwhile, the multi-screening system according to an embodiment of the present invention may include, in addition to the plurality of projection surfaces as described above, 'two or more projection devices' for projecting images on the plurality of projection surfaces, And a management device for controlling the at least two projection devices and the additional effect device.

Here, the ratio of the two or more projection devices including the cover projection device 150 or the projection device 320 for the 'other projection surface' may be variously configured according to the composition ratios of the plurality of projection surfaces.

On the other hand, the cover projection device 150 included in the two or more projection devices and the projection device 320 for the 'other projection surface' are configured to be similarly similar in terms of hardware although the objects to be projected are different from each other . Specifically, the cover projection device 150 and the projection device 320 for the 'other projection surface' may be implemented in various forms capable of projecting images on the projection surface. For example, the projection apparatuses can be classified into a method using a CRT, a method using a liquid crystal display (LCD), a digital light processing (DLP) method using a DMD (Digital Micromirror Device) A liquid crystal on silicon (Liquid Crystal on Silicon) method, and the like.

The additional effect device 340 is an apparatus for implementing additional effects other than images projected on the plurality of projection surfaces. Specifically, the additional effect device 340 is a device that adds a visual effect or adds an effect that allows the audience to feel with a sensation other than the time, in order to increase the feeling of immersion and realism that the audience can feel when watching the performance. Additional effects that the additional effect device 340 can provide include visual effects (e.g., presenting structures that match the image), sound effects, wind effects, odor effects, fog effects, temperature change effects, Effect, a soap bubble effect, a water injection effect, and the like. In addition to these effects, various effects related to human five senses can be included.

Therefore, the additional effect device 340 can stimulate human senses such as a speaker, a blower, a perfume sprayer, a fog machine, a light emitting device, a radiator, a cooler, a laser device, a soap drop generator, Lt; / RTI > devices.

In addition, the additional effect device 340 may be configured such that the additional effect device 240 exposes a structure that matches the reproduced image to a field of view of the audience (for example, a planet- Exposing the viewer to the field of view / exposing the remnants of the airplane (the structure) to the field of view of the viewer when the scene of the airplane crashes is reproduced).

Meanwhile, the 'projection device 320' and the additional effect device 340 may be installed at various positions in the interior of the movie theater, and preferably installed in the interior of the cover 100 . 5 to 6, the projection device 320 and the additional effect device 340, which are accommodated in the cover, may be integrally formed with the projection device 320 and the additional effect device 340, As shown in FIG. Therefore, with this structure, the projection device for the 'other projection surface' and the additional effect device may not be exposed to the audience, and the feeling of immersion felt by the audience may be further improved. (Distracted equipment is not exposed to the audience, so audience distraction is reduced and immersion is improved.)

The management device 400 is an apparatus for controlling various screening devices installed in an auditorium including the two or more projection devices and the additional effect device.
