Description

  The present invention relates to a screening hall structure and a “multi-screen screening system” using the same, and more particularly, that screening equipment (for example, a speaker, a projection device, a frame structure, etc.) is exposed in the direction of the audience seat. The present invention relates to a theater structure that is used to realize a “multi-screen screening system” by blocking and projecting an image on the surface.

Conventionally, in order to reproduce a movie, an advertisement, or the like in a theater, a two-dimensional image is projected onto a single screen arranged in front of the theater. However, under this type of system, the audience had to appreciate only the planar (two-dimensional) video.
Recently, technology related to 3D video that provides viewers with a 3D image has been developed. In 3D video technology, different images are placed in the human left and right eyes and can be combined in the brain. , Which uses the principle that a three-dimensional effect can be felt from a flat image, using two cameras with different polarization filters attached when shooting the image, and glasses with a polarization filter attached when viewing the image, etc. Wearing so that different images can enter the left eye and the right eye.

However, this type of 3D technology provides a stereoscopic image to the user, but it is still only for viewing an image reproduced on a single screen, and is less immersive to the image itself. There is a limit. In addition, there is a limit that the direction of the stereoscopic effect felt by the audience is limited to the direction in which a single screen exists.
In addition, the conventional three-dimensional technology requires wearing spectacles or the like with a polarizing filter when viewing the video, which may cause inconvenience to the viewer who views the video, and the left eye and the right eye In order to forcibly inject different images artificially, a sensitive audience may feel dizzy or upset.
For this reason, a so-called “multi-screen screening system” has been proposed in order to solve the problems of the conventional screening system based on a single screen. The projection surface is arranged, and synchronized images are projected onto a plurality of projection surfaces to provide a three-dimensional effect and an immersive feeling to the audience.

On the other hand, in order to realize such a “multi-screen screening system”, a plurality of projection surfaces are indispensable. For this reason, in order to build such a “multi-screen system” in a conventional screening hall having only a single projection surface (traditional screen), it is necessary to provide an additional projection surface inside the screening hall. It is.
However, it is never easy to provide a “traditional white or silver screen” in the already completed screening hall, which requires a lot of work. In some specific screening halls, it may be impossible to further provide a screen in view of the characteristics of the internal structure.

  In addition, a large number of screening equipment can be provided on the surface of the structural surface even if it is intended to use the “structural surface (wall surface, bottom surface, ceiling surface, etc.) itself” as a projection surface without providing a screen. Due to this, a normal projection surface is not realized. (Since the structural surface of the screening hall is equipped with various screening equipment as shown in Fig. 1, when the structural surface of the screening hall itself is used as the projection surface, only the images that are severely distorted due to the external shape of the screening equipment are displayed. This is to be realized.)

For this reason, “multiple projection surfaces” for multi-screen screening can be realized without providing a traditional screen inside the screening hall, and various screening equipment is provided on the surface of the structure. Even so, there is a need for a new technique capable of realizing “a plurality of normal projection planes (with less image distortion)”.
The present invention has been made to solve the above-described problems, and solves the above-mentioned problems and provides further technical elements that cannot be easily conceived by those having ordinary knowledge in this technical field. Invented for.

In addition, the items displayed in the attached drawings are schematic diagrams for easily explaining the embodiments of the present invention, and may be different from the forms actually realized.

On the other hand, each component to be described later is merely an example for realizing the present invention. Thus, in other implementations of the present invention, other components can be used without departing from the spirit and scope of the present invention. Each component may be realized only by a hardware or software configuration, or may be realized by a combination of various hardware or software configurations having the same function.
Further, the expression “comprising” a certain component is an “open expression”, is merely an expression indicating that the component exists, and should not be understood as excluding further components.

Furthermore, terms such as ordinal numbers such as “first, second, third” can be used to describe various components, but these terms can be used to refer to one component from another. Used to distinguish them from each other, and the attributes of these components are not limited by these terms.
Also, when a component is referred to as “connected” or “coupled” to another component, it may be directly coupled / connected to the other component, but between them, It should be understood that other components may be present.
On the other hand, the term “structural surface” used in the present specification means the surface that forms the internal structure of the theater. Such a “structural surface” includes various surfaces such as a ceiling surface, a bottom surface, and a wall surface formed inside the theater.

Further, the term “traditional screen” used in the present specification means a white screen, a gray-white screen, a silver screen, etc., which are mainly provided in a conventional theater.
Furthermore, the term “another projection surface” used in the present specification is a term indicating all projection surfaces except a projection surface (a surface of a cover described later) formed by a theater structure according to the present invention. . For this reason, "other projection surfaces" include various projection surfaces such as traditional screens and wall surfaces.

Hereinafter, a theater structure according to an embodiment of the present invention will be described with reference to FIGS.
Referring to FIG. 2, a screening structure according to an embodiment of the present invention includes a screening equipment 200 provided inside the screening hall and a cover 100 for blocking the screening equipment from being exposed in the direction of the audience seat. The surface of the cover 100 is utilized as a projection surface on which an image is projected.
The screening equipment 200 means various equipment provided inside the screening hall for the screening itself or to assist the screening.
Such a screening equipment 200 includes a projection device, an acoustic device (speaker, etc.), a light emitting device, a blower, a scent ejector, a fog machine, a heater, a cooler, a laser device, a soap bubble generator, and a light emitting diode (LED). , Water jetting device, vibration device, frame structure where the device is installed, various structures formed inside the screening hall such as the internal skeleton structure of the screening hall, in addition to these examples, the structural surface of the screening hall Various equipment formed on top.

On the other hand, conventional screening halls are equipped with these screening equipment on the structural surfaces other than the front (left side, right side, back, bottom, ceiling, etc.) where “traditional screens” are provided. It was difficult to further provide a “traditional screen”. Also, when trying to use the structural surface itself as a projection surface, a normal projection surface is realized due to the image distortion caused by the screening equipment (physical outline of the screening equipment) provided on the surface. Was not.
The present invention further includes a cover 100 for blocking the external exposure of the screening equipment in such a conventional screening theater, and uses the “surface of the cover 100 itself” as a projection surface, whereby the structure of the conventional screening theater is provided. A smooth projection surface (with less image distortion) can be further formed without changing the position or changing the installation position of the screening equipment.

The cover 100 is a component for blocking the screening equipment from being exposed in the direction of the audience seat as described above. Specifically, the cover 100 is formed between the screening equipment provided on the structural surface (wall surface, ceiling surface, bottom surface, etc.) and the audience seat, and the structural surface or the screening equipment is exposed in the direction of the audience seat. It is a component for blocking what is done.
Such a cover 100 is preferably provided with a surface without unevenness, but this is because it serves as a smooth projection surface (projection surface with less image distortion) based on such a surface without unevenness. For this reason, the cover 100 can smoothly reproduce the image projected by the cover projection device 150 using the surface without unevenness in a state where the exposure of the screening equipment 200 and the structural surface is blocked, such an operation. Can be used to provide further images to the audience. On the other hand, the direction in which an image is projected on the surface of the cover 100 is variously configured. For example, an image may be projected from the outside of the cover 100 onto the outer surface of the cover 100 (the embodiment of FIG. 2), and an image is projected from the inside in which the screening equipment 200 is accommodated onto the inner surface of the cover 100 (see FIG. 2). (Not shown).

Further, the cover 100 is formed in a lid shape having a space formed therein, and is detachably formed on the structural surface of the theater. For this reason, the cover 100 can accommodate the screening equipment using a space, and even when the equipment needs to be further provided, the equipment can be further accommodated using the attaching / detaching operation of the cover 100. it can.
Furthermore, the cover 100 includes variously shaped surfaces. Specifically, the cover 100 includes a surface having various shapes such as a dome shape, a polygonal shape, and a circular shape. The cover is manufactured in various shapes according to the characteristics of the content to be screened (movie, advertisement, etc.) or the characteristics of the screening hall, and is applied to the screening hall.
Furthermore, as will be described later, the cover 100 includes a surface on which an optical coating layer is formed. For this reason, it is possible to realize a high-quality projection surface by using the surface on which such an optical coating layer is formed, and it is possible to reduce a different texture that occurs between other projection surfaces.

Furthermore, the cover 100 includes a gradation hue as described later. Specifically, a gradation-like hue is formed on the outer edge portion of the cover 100. Even if the hue of the cover 100 and the hue of the adjacent projection surface are completely different due to such a gradation-like hue, The different texture near the boundary is alleviated.
Furthermore, the cover 100 further includes an opening, as will be described later. For this reason, the operation of the screening equipment 200 accommodated inside the cover can be transmitted to the outside of the cover 100 through such an opening. For example, a projection device accommodated in the cover 100 projects an image on a projection surface disposed outside through the opening, or an additional effect device accommodated in the cover via the opening. Transmit additional effects (sound, fragrance, water jet, wind, etc.) to the outside.
The cover 100 further includes an opening that is opened and closed by electrical control, as will be described later. For this reason, using such a configuration, basically, a sealed surface on which images are smoothly projected is realized, but as necessary, the opening can be selectively opened and closed to operate the screening equipment. Communicate outside.

Furthermore, a synchronized video is projected onto the surface of the cover 100, as will be described later. Specifically, an image synchronized with the image projected on the projection surface provided in the theater is projected on the surface of the cover 100. For this reason, the surface of the cover 100 creates a multi-screen screening environment together with the projection surface provided in the screening hall, and provides a multi-screen video with a sense of unity in synchronization with the audience.
Furthermore, a corrected image is projected onto the surface of the cover 100 as will be described later. Here, the correction is correction in consideration of the surface, hue, chromaticity, brightness, reflectance, material, and the like. In addition, the correction is a correction that takes into account the difference in properties between the “surface of the cover 100” and the projection surface provided in the theater. Specifically, the correction is correction for canceling the property difference (hue difference, chromaticity difference, brightness difference, reflectance difference, shape difference, material difference, etc.) between the “cover surface” and the projection surface. .

Referring to FIG. 3, a theater structure according to an embodiment of the present invention includes a cover 100 formed in a dome shape.
Specifically, a theater structure according to an embodiment of the present invention includes a cover 100 formed on a structural surface such as a ceiling surface, a bottom surface, or a wall surface. Here, the cover 100 is preferably illustrated in FIG. As shown, it has a dome-shaped surface.
For this reason, the theater structure according to the embodiment of the present invention surrounds the audience seat using the dome shape itself, and in this state, projects an image on the dome-shaped surface (the surface of the cover 100). To maximize the immersive feeling felt by (This is because the audience feels that they are surrounded by video.)
In particular, when a multi-screen screening system is realized using the surface of the dome-shaped cover 100, the audience is primarily surrounded by a plurality of projection surfaces, and the dome-shaped also in a specific direction in which the cover 100 exists. Therefore, the three-dimensional effect and the immersive feeling felt by the audience are further maximized.

Referring to FIG. 4, the theater structure according to the embodiment of the present invention forms an optical coating layer 110 on the surface of the cover 100.
Specifically, a theater structure according to an embodiment of the present invention includes an optical coating layer 110 formed on the surface of the cover 100, and the optical coating layer 110 is used to form a high quality on the surface of the cover 100. Can be realized. For this reason, the theater structure according to the embodiment of the present invention can achieve substantially the same level of image quality as other projection surfaces provided in the theater using the optical coating layer 110. Due to the improvement in quality, a different texture generated between the images on the other projection surfaces is reduced.
The optical coating layer 110 is a component for improving the optical properties of the surface of the cover 100. Such an optical coating layer 110 changes the surface of the cover 100 to a smooth shape (a shape without irregularities), or changes the surface material of the cover 100 to optical characteristics (polarization characteristics, reflectance characteristics, scattering characteristics, etc.). Or change to an excellent material.

On the other hand, the optical coating layer 110 is formed by various methods. Typically, the optical coating layer 110 is formed by a method of applying an optical paint. Specifically, the optical coating layer 110 is formed by applying an optical paint that improves optical characteristics to the surface of the cover 100. Here, the optical paint includes substances of various types or in various states, and includes, for example, a fluid serving as particle particles and a particle particle carrier for improving optical properties.
The particle particles mean particles included in the optical coating layer 110 in order to improve optical characteristics. Such particle particles include various fine particles for improving optical properties. For example, metal particles having excellent reflection characteristics (for example, aluminum), dielectric particles having excellent optical properties (for example, aluminum) , Silicon oxide particles, magnesium fluorinated particles, etc.). On the other hand, the particle particles are formed by cutting or pulverizing an optical substrate including a metal layer (for example, an aluminum layer) or a dielectric layer (for example, a silicon oxide layer). That is, the particle particles are formed by transforming the optical substrate on which the metal layer or the dielectric layer is formed into small particles using a physical method.
In addition, the fluid is a component that serves as a carrier that enables application of particle particles. Such a fluid is composed of various fluid substances, but is preferably composed of substances such as PVC resin, enamel, polyurethane, acrylic resin, and lacquer.

Hereinafter, with reference to FIG. 5, an example in which an opening is formed in a theater structure according to an embodiment of the present invention will be described.
Referring to FIG. 5, the cover 100 includes an opening 120 that exposes a part of the screening equipment accommodated therein.
For this reason, the operation of the screening equipment 200 accommodated in the cover 100 is transmitted to the outside through the opening 120. For example, as shown in FIG. 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 or the light projected by the light emitting device 230 is external. Is transmitted to.

On the other hand, in this case, the opening 120 is preferably formed to a minimized size. Specifically, it is preferable to form a size that exposes only the minimum configuration necessary for transmitting the operation of the screening equipment 200 to the outside. When the surface of the cover 100 is used as a projection surface, the size of the opening 120 needs to be minimized because the image may be distorted by the opening 120 (the physical shape of the opening. Therefore, the opening 120 is preferably formed in a minimized shape such as a size for exposing only the lamp of the projection device 220 to the outside and a size for exposing only the lamp of the light emitting device 230.
Specifically, referring to FIG. 5, a theater structure according to an embodiment of the present invention includes a projection device 220 and a cover 100 that houses a screening equipment 200 such as a light emitting device 230. 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. Further, the opening 120 is formed in a minimized size that exposes only the lamp of the projection device 220 or the lamp of the light emitting device 230 to the outside.

Therefore, as shown in FIG. 5, even when the image is projected on the surface of the cover 100, the projection device 220 accommodated in the cover 100 is placed on the “other projection surface” around which the projection device 220 is arranged. Can project images. (On the other hand, unlike the embodiment of FIG. 5, when another cover is arranged around the cover 100, the projection device 220 housed inside the cover 100 projects an image on the surface of the other cover. ).
On the other hand, in the case where the opening 120 is formed in the cover 100, even if the opening 120 is formed in a minimized size, there is a possibility that image distortion may occur due to the presence of the opening 120. For this reason, in the present invention, the corrected image is projected onto the surface of the cover 100 including the opening 120. Specifically, the present invention corrects the image so as to cancel the distortion caused by the opening 120 after analyzing the distortion information caused by the opening 120. For example, the present invention analyzes the information that the opening 120 distorts the hue of the image to correct the image, or analyzes the information that the opening 120 distorts the geometric shape of the surface to analyze the shape. to correct. In the present invention, an image is corrected by analyzing information such as a brightness difference and a reflectance difference caused by the opening 120.
Such a correction operation is performed by various devices including a management device described later.

Hereinafter, an example in which an opening that can be opened and closed is formed in a theater structure according to an embodiment of the present invention will be described with reference to FIG.
A theater structure according to an embodiment of the present invention includes an opening 120 that can be opened and closed. Specifically, the structure according to an embodiment of the present invention is opened when the operation of the screening equipment 200 accommodated in the cover 100 needs to be transmitted to the outside, and transmits the operation of the screening equipment to the outside. It includes an opening 120 that is closed when not needed. For this reason, by using such an openable / closable opening 120, the time for the screening equipment 200 to be exposed to the outside is minimized, and the time for realizing the smoothest projection surface on the surface of the cover 100 is maximized.

Such an opening 120 selectively exposes various screening equipment 200 to the outside. Specifically, the opening 120 selectively exposes the projection device 220, the light emitting device 230, the additional effect device 240, and the like housed in the cover 100 only to a specific viewpoint using such an opening / closing operation. .
Meanwhile, a theater structure according to an exemplary embodiment of the present invention accommodates a movable additional effect device 240 inside a cover 100. Specifically, as shown in FIG. 6, the theater structure is provided to be movable (for example, fixed to a linear or rotationally movable frame and movable by the movement of the frame). An effect device 240 is provided. For this reason, in such an embodiment, when the opening 120 is opened, the additional effect device 240 is completely exposed to the spectator seat by exercise, and when the opening 120 is closed, the additional effect device 240 is opened. Is completely accommodated inside the cover 100 by movement.

For reference, the additional effect device 240 is a device for realizing an additional effect other than video, and is realized by various screening equipment. For example, the additional effect device 240 exposes a structure aligned with the reproduced image to the viewer's field of view (for example, when a scene where a meteor falls in outer space is played back, the meteor-like structure is exposed to the viewer's field of view. It is configured as a device that exposes the aircraft's devastation (structure) to the spectator's field of view when the scene where the airplane is exposed / crash is reproduced, or in addition to these devices, a speaker, a blower, a scent It is configured as various devices that stimulate human senses, such as an injector, fog machine, light emitting device, heater, air conditioner, laser device, bubble generator, light emitting diode (LED), and water injector.
On the other hand, the opening / closing operation of the opening 120 and the operation (movement) of the additional effect device 240 are controlled by various devices including a management device described later. In this case, the opening / closing operation of the opening 120 and the operation of the additional effect device 240 are controlled so as to be linked 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 are controlled based on the time code of the video data projected on the surface of the cover 100 or another projection surface, and operate from a specific viewpoint on the time code. To be controlled.

In the present invention, a “multi-screen screening system” is constructed using the above-described screening hall structure.
First, the present invention realizes a “multi-screen screening system” by using a plurality of “other projection surfaces 300” and the surface of the cover 100 provided in the theater. For example, as shown in FIG. 7, another projection surface 300 is arranged on the front, left side, right side, and bottom, and a cover 100 is arranged on the ceiling, and the front, left side, right side, bottom, and top are arranged. Realize a “multi-screen screening system” in which video is played back on the side (ceiling surface). (For reference, in the embodiment shown in FIG. 7, the reason why the projection surface of the ceiling is realized by the cover 100 is that various screening equipments are usually provided in a complicated manner on the ceiling of the screening hall. This is because it is difficult to realize the projection surface that has.)
In addition, the present invention is not limited to the ceiling, and when the screening equipment is complicatedly provided on the bottom, left side, right side, front, or back, the bottom, left side, right side, front, or back is provided. Also, a cover 100 that is not “another projection surface 300” is provided. For this reason, in such an embodiment, two or more projection surfaces among a plurality of projection surfaces for realizing multi-screen presentation are realized using a cover.
Furthermore, the present invention uses the cover 100 to realize all projection surfaces for realizing a multi-screen screening system. For example, the cover 100 is formed on all of the front, left side, right side, ceiling, and bottom of the screening hall, and a plurality of projection surfaces are realized using a plurality of covers.

On the other hand, as described above, the “other projection surfaces 300” include various projection surfaces other than the projection surfaces realized using the surface of the cover 100. Specifically, the “other projection surfaces 300” include various projection surfaces on which an image is projected, such as “screen” and “structural surface”.
Here, the “screen” is a component that reflects an image projected by a projector or the like to allow the audience to view the image, and is variously formed within a range in which such a function is performed.
For example, the screen is PVC screen, PVC screen coated with white, PVC screen coated with pearl luster, PVC screen coated with aluminum, matte screen, lenticular screen, glass bead screen, silver screen, high gain screen, etc. It is formed as a screen of various materials. The screen is formed as various types of screens such as an electric embedded screen, an electric exposure screen, a wall-mounted screen, a triangular trapezoid screen, a road warrior screen, a high brightness screen, and a sound screen. Furthermore, the screen is formed as a screen such as a water screen, a fog screen, a holographic screen, or a miracle screen (screen using magic glass), and in addition to these, various screens are formed.

On the other hand, the screen is formed by an object that does not belong to the range of “traditional screen” or an object whose unique name itself is not a screen. (In other words, even if the specific name of the specific object itself is not a screen, the object is included in the range of the screen as long as the surface of the specific object serves as a video projection surface.) As long as an object such as a panel or curtain is provided on the screen, and the surface image of the object is projected, the object is included in the range of the screen regardless of the unique name.
In addition, as described above, the “structural surface” means a structural surface formed inside the theater, and includes a ceiling surface, a bottom surface, a wall surface (a front wall surface, a left wall surface, a right wall surface, Various surfaces such as the back wall).

On the other hand, the present invention projects synchronized images on a plurality of projection surfaces after a multi-screen screening system is constructed. For this reason, the present invention projects synchronized video on a plurality of projection surfaces arranged so as to surround the audience, and makes the audience feel as if they are actually in the scene where the video is drawn.
In addition, the present invention projects images corrected differently from each other on a plurality of projection surfaces after a multi-screen screening system is constructed. Specifically, 1) the present invention realizes a part of a plurality of projection surfaces using the cover 100 and the other using the “other projection surfaces 300”, and the surface of the cover 100 Considering the property difference (hue, chromaticity, brightness, shape, reflectivity, etc.) from the “other projection surface 300”, the image projected on the surface of the cover 100 and the “other projection surface 300” The projected images are corrected to be different from each other. When the images corrected in the same manner are projected in a state where the surface of the cover 100 and the “other projection surface 300” have different properties, the images reproduced on the two projection surfaces cause different textures. This is because the immersive feeling of the audience may be reduced. 2) Further, according to the present invention, when two or more covers 100 having different properties are included on a plurality of projection surfaces, images corrected to be different from each other are projected onto the surfaces of the two or more covers 100. . 3) Further, according to the present invention, when two or more “other projection surfaces 300” having different properties are included in a plurality of projection surfaces, the two or more “other projection surfaces 300” are different from each other. Project a corrected image.
In short, according to the present invention, when a multi-screen presentation system is constructed using a plurality of projection surfaces having different properties from each other, images corrected differently from each other are projected onto the plurality of projection surfaces.

Here, the above correction is correction in consideration of the surface shape difference. That is, on the plurality of projection surfaces, images corrected to be different from each other are projected in order to cancel the surface shape difference of the images corrected to be different from each other in consideration of the surface shape difference.
Further, the correction is correction in consideration of hue difference or chromaticity difference. That is, on the plurality of projection surfaces, images corrected to be different from each other in order to cancel the hue difference or chromaticity difference of the image surface corrected to be different from each other in consideration of the hue difference or chromaticity difference of the surface. Projected.
Furthermore, the above correction is a correction in consideration of the brightness difference. That is, on the plurality of projection surfaces, images corrected to be different from each other are projected in order to cancel the brightness difference on the image surface corrected to be different from each other in consideration of the brightness difference on the surface.
Furthermore, the above correction is a correction in consideration of the reflectance difference. That is, on the plurality of projection surfaces, images corrected so as to be different from each other are projected in order to cancel the difference in image reflectivity corrected to be different from each other in consideration of the difference in reflectance.
Furthermore, the above correction is a correction in consideration of various characteristic differences in addition to the above-described features.

On the other hand, the process of correcting the images projected on the plurality of projection surfaces in consideration of the difference in properties of the plurality of projection surfaces is different from each other because the purpose of the correction is to cancel the different textures. Preferably, this is done so as to reduce the difference.
Typically, the correction considering the chromaticity difference information of a plurality of projection planes will be described. (The process described later is, of course, the correction considering the hue difference, brightness difference, reflectance difference, shape difference, etc. First, the chromaticity difference information between the projection planes is calculated in consideration of the chromaticity information of each projection plane. Specifically, after setting one reference projection plane, The relative chromaticity difference information of each projection surface is calculated. For example, “A projection plane has a chromaticity level of R (red) 50 higher than a reference projection plane, a chromaticity level of G (green) is 40 levels higher, and a chromaticity level of B (blue) is the same. Relative chromaticity difference information is calculated using a method such as “Yes”. After the chromaticity difference information of each projection surface is calculated in this way, the image is corrected using the calculated information. For example, “R is 50 for the chromaticity of the image projected on the A projection surface. Correction is performed using a method of “lower level, G lower by 40 level, and maintain B level”. For this reason, the chromaticity difference of the projection surface is canceled out by such a process.
On the other hand, the property difference analysis of a plurality of projection surfaces is variously performed using a method other than the setting of the reference projection surface. For example, after calculating a representative value (average value, median value, mode value, etc.) relating to the properties of a plurality of projection surfaces, a relative characteristic difference is analyzed using the calculated representative value as a reference.

Meanwhile, the multi-screen screening system according to an embodiment of the present invention includes a cover 100 in which a gradation hue is formed on the outer edge. Here, the gradation hue is preferably formed based on the hue of the cover 100 and the hue of the adjacent projection surface. For example, when the hue of the cover 100 is black and the hue of the adjacent projection surface is white, it is preferable that the gradation hue represents a change in hue between black and white.
Therefore, according to the present invention, when such a gradation hue is used, when the surface of the cover 100 and the “other projection surface 300” have surfaces of different hues, different textures caused at the boundary of the projection surface. To ease. The present invention also includes two or more covers 100 adjacent to a multi-screen screening system, and even if the two or more covers 100 have different hues, the boundary between the covers 100 using gradation hues. Relieve the different texture caused by

In the multi-screen screening system of FIG. 8, “other projection surfaces 300” are arranged on the front, left side, and right side, and the cover 100 is arranged on the ceiling. There is a possibility that a different texture is formed near the boundary of the projection surface due to the formation of different hues. However, the present invention forms a gradation hue on the outer edge of the cover 100 to prevent a sudden strange texture that occurs near the boundary.
