However, the two or more projection devices include a refracting projection device that refracts before the projection light reaches the projection surface.

Description

  The present invention relates to a “multi-screen screening system” that refracts projection light of a projection device, and more specifically, a multi-surface formed in a form in which all or part of the projection light of the projection device constituting the multi-screen screening system is refracted. It relates to the screening system.

  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.

  In recent years, technology related to 3D video that provides viewers with stereoscopic images has been developed. However, 3D video technology uses different images in the viewer's left and right eyes, and the left and right images in the brain. When the images are combined, it uses the principle that a stereoscopic effect can be felt from a flat image, and two cameras with different polarization filters are attached when shooting the image. Wearing glasses with a filter attached to the left eye and right eye so that different images can enter each other.

  However, although this type of 3D technology provides a stereoscopic image to the user, 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.

  Furthermore, 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 audience watching the video, and the left eye In addition, because different images are forcibly injected into the right eye artificially, a sensitive audience may feel dizzy or upset.

For this reason, a so-called “multi-screen screening system” has been proposed to solve the problems of the conventional screening system based on a single screen.
Here, the “multi-screen screening system” means that a plurality of projection surfaces are arranged around the audience seats, and synchronized images are projected on the plurality of projection surfaces to provide a three-dimensional effect and an immersive feeling to the audience. Means technology.

  On the other hand, in order to realize such a “multi-screen screening system”, “two or more projection devices” for arranging “a plurality of projection surfaces” around the audience seat and projecting images on the plurality of projection surfaces Must be provided. In this case, if the projection surface and the projection device are provided so as to face each other as in a normal screening system (screening system of a single projection surface), various problems may occur. (That is, if the “plurality of projection surfaces” and the “two or more projection devices” are provided so as to face each other, various problems occur.)

For example, since the two or more projection devices provided so as to face the plurality of projection surfaces may be arranged in a complicated manner within the visible range of the audience, there is a problem that the immersive feeling of the audience decreases.
Further, there is a problem that projection devices arranged to face opposite projection surfaces (for example, left projection surface / right projection surface, front projection surface / rear projection surface, etc. of the audience seat) may interfere with each other's projection operation. Also occurs.

Furthermore, when the two or more projection devices are provided so as to face the plurality of projection surfaces, it is difficult to secure an installation space, so it is necessary to install some projectors on the floor surface. The projector provided on the floor may cause an accident in the screening process, which is problematic in terms of safety. In other words, since the screening hall is dark, there is a risk that the audience will trip over the projection device provided on the floor and fall down.
For this reason, there is a need to develop a new “multi-screen screening system” that improves the above problems.

  It is an object of the present invention to provide a “multi-screen screening system” that refracts the projection light of a projection device and projects an image on a projection surface using the refracted projection light.

  A multi-screen screening system according to an embodiment of the present invention for solving the above-described problem includes a plurality of projection surfaces arranged in a state that are not parallel to each other, and two or more for projecting images on the plurality of projection surfaces. A projection device, wherein the two or more projection devices include a refraction projection device in which the projection light is refracted before reaching the projection surface.

In addition, it is preferable that the multi-plane screening system further includes a projection light refracting unit for refracting the projection light of the refractive projection device.
It is preferable that the projection light refracting unit changes an angle at which the projection light of the refractive projection device is refracted by using the motion of the main body. The projection light refracting unit projects the projection light of the refractive projection device by the motion of the main body. Is preferably selectively made to reach all of the plurality of projection surfaces.

The present invention is characterized in that a plurality of refractive projection devices and projection light refracting units are provided, and each projection light refracting unit refracts the projection light of each refractive projection device.
The plurality of refractive projection devices are preferably installed in a space that does not affect the visual field of the audience.

  The present invention further includes a management device for controlling a plurality of refraction projection devices and a plurality of projection light refraction units, wherein the management device controls each projection light refraction unit to refract the projection light of each refraction projection device. The angle is controlled.

Preferably, the management device controls an angle at which the projection light of each refractive projection device is refracted so that each refractive projection device selectively projects an image on all of the plurality of projection surfaces.
The management device stores the identification information of each refractive projection device and the operation information of each projection light refraction unit in association with each other, and the operation information of each projection light refraction unit includes a plurality of operation mode information. To do.

  The management device analyzes performance information of a plurality of refractive projection devices, selects a refractive projection device to be used for video projection, and controls the angle at which the projection light of the selected refractive projection device is refracted. It is preferable to project an image on the projection surface.

The performance information is preferably light intensity information of the refractive projection apparatus, resolution information of the refractive projection apparatus, or maintenance information of the refractive projection apparatus.
The two or more projection devices include a main projection device for projecting an image on a main projection surface.

The present invention further includes an auxiliary projection device for projecting an image on an auxiliary projection surface arranged around the main projection surface, and the auxiliary projection device is formed in the form of a refractive projection device.
The main projection device and the auxiliary projection device are preferably installed in a space that does not affect the visual field of the audience.
Preferably, the auxiliary projection device projects an image during the entire time or a specific time when the main projection device projects an image, and the projection light of the auxiliary projection device is projected after being refracted.

The refraction projection device projects an image on the main projection surface instead of the main projection device when an abnormality occurs in the operation of the main projection device.
It is preferable that a plurality of the refractive projection devices are arranged, and the refractive projection device analyzed as having the highest performance among the plurality of refractive projection devices projects an image instead of the main projection device.

When the types of the plurality of projection surfaces are different, the two or more projection devices project a corrected image, and the correction is performed such that a property difference between the plurality of projection surfaces is canceled out. And
The property difference is preferably a brightness difference, a chromaticity difference, or a reflectance difference.

  According to the present invention, it is possible to reach the projection surface after the projection light projected by the projection device is refracted. For this reason, even if it provides so that a projection surface and a projection apparatus may not face each other, the projection light of a projection apparatus can reach a projection surface.

  Further, the present invention can refract the projection light of a single projection device at various angles. For this reason, according to this invention, an image | video can be selectively projected on the several projection surface of a single projection apparatus. For example, the present invention refracts the projection light of a single projection device and projects an image on the A projection surface of the single projection device, projects an image on the B projection surface, or C projection. An image can be projected on a surface, or an image can be projected on another projection surface included in a plurality of projection surfaces.

For this reason, it is possible to project an image on a plurality of projection surfaces arranged in a single theater without affecting the immersive feeling of the audience and without affecting the projection surfaces of each other.

Furthermore, the present invention can provide a larger number of projection devices (projection devices in which the projection light is refracted) than the number of projection surfaces arranged in the theater, and the performance information of the projection device ( After analyzing the brightness, resolution, maintenance information, etc.), it is possible to select and use only a projector having excellent performance. For this reason, since the performance of the projection apparatus utilized for video projection is guaranteed, the quality of the projected video is guaranteed.
In addition, since the projection apparatus in which abnormality occurred in performance is excluded automatically, even if abnormality occurs in the operation of a specific projection apparatus, the system operates normally.

  Furthermore, according to the present invention, when an abnormality occurs in the operation of the main projection device, the main projection device can be replaced with an auxiliary projection device. Specifically, when an abnormality occurs in the operation of the main projection device, the main image is sent to the auxiliary projection device to project the main image, and the projection light of the auxiliary projection device is refracted to reach the main projection surface. Therefore, the auxiliary projection device can be replaced with the main projection device.

  Furthermore, according to the present invention, when selecting an auxiliary projection device that performs the operation of the main projection device, the performance information of each auxiliary projection device can be analyzed, and the auxiliary projection device analyzed as having the highest performance. The operation of the main projection device can be substituted. For this reason, it is possible to project an image with the best quality even in a situation where an abnormality has occurred in the main projection device.

  Hereinafter, with reference to the accompanying drawings, a “multi-screen screening system that refracts projection light of a projection apparatus” according to the present invention will be described in detail. The embodiments to be described are provided so that those skilled in the art can easily understand the technical idea of the present invention, and the present invention is not limited thereto. 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, 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.

In the following, with reference to FIGS. 1 to 4, a multi-screen screening system as the basis of the present invention will be described.
The multi-screen screening system that forms the basis of the present invention provides images synchronized with each other through a plurality of projection surfaces provided in a single screening hall, and by using such a screening environment, the audience can start from the video. It means a video system that maximizes the sense of reality, stereoscopic effect, and immersion. In other words, the multi-screen screening system means a system in which a plurality of projection surfaces are provided in a single screening theater and synchronized images are provided to the audience through the plurality of projection surfaces thus provided.

  The plurality of projection surfaces are a plurality of projection surfaces provided in a single theater for multi-screen screening. A plurality of images are reproduced on the plurality of projection surfaces. Here, the plurality of images reproduced on the plurality of projection surfaces are synchronized with each other to form an image with a sense of unity as a whole. Is preferred. That is, a plurality of different images are simultaneously reproduced on each projection surface. However, when viewed from the whole of the plurality of projection surfaces, the images on each projection surface are synchronized with each other to give a sense of unity to the audience. It is preferable to form an image. On the other hand, depending on the situation, different videos may be reproduced on each projection plane, or different videos may be reproduced only on some projection planes.

On the other hand, the plurality of projection surfaces reproduce an image using the entirety of the plurality of projection surfaces, or reproduce an image using only a part of the plurality of projection surfaces.
For example, the plurality of projection surfaces reproduce an image only on a specific projection surface and do not reproduce an image on the remaining projection surfaces (state 1), only on a part of the plurality of projection surfaces. Video content can be realized either in a state in which video is reproduced and no video is reproduced on the remaining projection surfaces (state 2) or in a state in which video is reproduced on all projection surfaces (state 3). These states 1 to 3 may be alternately realized in the screening process.

  Further, the plurality of projection surfaces are arranged so as not to be parallel to each other. The conventional technology is a method in which an image is projected only on a two-dimensional screen arranged in front of the theater, and the audience views the image reproduced on the screen, or the image reproduced on a plane. Whereas the 3D technology is applied to itself, the multi-screen screening system that forms the basis of the present invention arranges a plurality of projection surfaces in a three-dimensional manner so as not to be parallel to each other. Even without applying a three-dimensional technique or the like, a plurality of projection surfaces arranged in a three-dimensional manner are used to provide an image with a high stereoscopic effect and immersiveness to the audience.

  Further, the plurality of projection surfaces are preferably arranged in a non-parallel state, and more preferably arranged so as to surround the audience seats in the exhibition hall. For this reason, the synchronized video realized by multiple projection surfaces gives the audience a sense of being surrounded by the space created by the video, which makes the viewer feel the three-dimensional and immersive feeling. And virtual reality is maximized.

Furthermore, the angle formed by the plurality of projection surfaces is not limited to a specific angle, and may be arranged at various angles as long as the viewer feels a stereoscopic effect.
Furthermore, although the plurality of projection surfaces are adjacent or spaced apart from each other, it is preferable that the plurality of projection surfaces be arranged so as to surround the audience seat.

  FIG. 1 is an embodiment in which a plurality of projection surfaces are arranged on the front, left side, and right side with respect to the audience seat, and FIG. 2 is a front view, left side, right side on the basis of the audience seat. It is embodiment arrange | positioned at a surface and an upper surface (ceiling). FIG. 3 is an embodiment in which a plurality of projection surfaces are arranged on the front surface, left side surface, right side surface, top surface (ceiling), and bottom surface (bottom surface) with respect to the audience seat.

FIG. 4 is an exemplary diagram showing a multi-screen screening system in which a plurality of projection surfaces, two or more projection devices, and a management device are arranged.
As shown in FIG. 4, the multi-screen screening system further includes two or more projection devices 300 for projecting images on a plurality of projection surfaces, and further includes a management device 400 that controls operations of the two or more projection devices 300. Prepare.

  The two or more projection devices 300 are components that project an image on the plurality of projection surfaces described above. These two or more projection apparatuses 300 can be realized by various systems so as to include an optical system and a heat generating unit. For example, the projection apparatus 300 includes a system using a cathode ray tube (CRT), a liquid crystal display (LCD). A method used, a digital light processing (DLP) method using a digital mirror device (DMD) chip, a reflective liquid crystal element (LcoS: Liquid Crystal on Silicon) method, and the like. In addition to this, it can be realized by various methods.

  The management device 400 is a component that controls the operation of two or more projection devices 300. Such a management apparatus 400 is connected in parallel with two or more projection apparatuses 300, and controls the two or more projection apparatuses 300 individually or in an integrated manner using such a parallel connection. Moreover, the management apparatus 400 manages the image | video which two or more projection apparatuses 300 project integrally, and correct | amends the image | video which each projection apparatus 300 projects as needed. On the other hand, the management apparatus 400 controls not only the operations of the two or more projection apparatuses 300 but also the operations of various apparatuses incorporated in the multi-screen presentation system.

The management device 400 may be realized by various electronic devices, may be realized by one electronic device, or may be realized by connecting a plurality of electronic devices to each other.
For example, the management device 400 may be realized by a single server device or may be realized by connecting two or more servers to each other. The management device may be realized by connecting a server and another electronic device to each other, or may be realized by an arithmetic device other than the server.

  On the other hand, the management device 400 is realized by a plurality of server devices connected in a hierarchical manner. For example, the management apparatus 400 is realized such that one main server and a plurality of slave servers are connected. In this case, a plurality of slave servers share and control devices provided in the multi-screen screening system. For example, the slave server 1 controls the projection devices 300A to 300D, the slave server 2 controls the projection devices 300E to 300H, etc., and one main server comprehensively manages the control operations of the plurality of slave servers.

On the other hand, the plurality of projection surfaces constituting the multi-screen screening system are formed in various shapes such as a screen and an internal structure surface (bottom surface, wall surface, ceiling surface, etc.) of the screening theater.
The plurality of projection surfaces are all formed on the same type of projection surface, but are preferably formed on a plurality of types of projection surfaces. For example, the plurality of projection surfaces are
i) different types of screens,
ii) different types of internal structural surfaces,
iii) different types of screens and internal structural surfaces,
The projection surfaces are of different types.

However, when a plurality of projection planes are formed using different types of projection planes as described above, different textures may occur between images reproduced by the plurality of projection planes.
Specifically, since the properties of the projection surfaces forming the plurality of projection surfaces are different, different textures are generated between the images projected on the projection surfaces. It is necessary to remove the different textures between these images because the different textures of these images may hinder the audience's immersive and stereoscopic effect.

The present invention performs an image correction operation in consideration of such a difference in properties between a plurality of projection surfaces, and improves a different texture between images reproduced on the plurality of projection surfaces through the image correction operation.
The video correction work will be described in detail.
1) a first step of analyzing a property difference between a plurality of projection surfaces;
2) a second step of performing image correction based on the property difference information between the plurality of analyzed projection surfaces so that the property difference is canceled;
including.

  The step of analyzing the property difference between the plurality of projection surfaces in the first step is preferably performed by the management device 400. In this case, the management apparatus 400 analyzes the property difference information between a plurality of projection planes by various methods. Typically, a method that utilizes information stored in an internal database, and a method that utilizes an imaging device. Analyzing property differences between multiple projection surfaces using various methods.

Here, the method of utilizing the database (DB) is a database in which individual property information regarding a plurality of projection surfaces, for example, chromaticity information, brightness information, reflectance information, image quality information, and the like are stored in a database. Reference numeral 400 denotes a method of analyzing property difference information between a plurality of projection planes by utilizing information included in such a database (DB).
In addition, the method of using the image capturing device means a method of providing an image capturing device that captures a plurality of projection surfaces and comparing / analyzing images captured by the image capturing device to analyze property difference information between the projection surfaces. .

  The step of correcting the image so as to cancel the property difference based on the property difference information between the plurality of projection surfaces in the second step is also preferably performed by the management device 400. In this case, the management apparatus 400 cancels the analyzed property difference based on information such as a property difference between a plurality of projection surfaces analyzed by itself, such as a chromaticity difference, a brightness difference, a reflectance difference, and an image quality difference. Thus, the image projected on each projection surface is corrected. Thereby, the different texture between the images reproduced on the plurality of projection surfaces is reduced.

As a representative example, correction that considers chromaticity difference information of a plurality of projection surfaces will be described. The process described later is naturally applied by analogy to correction that takes into account differences in brightness, reflectance, and image quality.
First, the management device 400 calculates chromaticity difference information between the projection surfaces in consideration of chromaticity information of each projection surface. Specifically, after setting one reference projection surface, each management surface 400 Relative chromaticity difference information 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, the chromaticity of the image projected on the projection surface A is corrected using a method in which R is 50 levels lower, G is 40 levels lower, and B level is maintained. For this reason, the hue difference of the projection surface is canceled.

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 relating to the properties of the plurality of projection surfaces, for example, an average value, a median value, a mode value, etc., a relative characteristic difference is analyzed using the calculated representative value as a reference.
Hereinafter, with reference to FIGS. 5 to 9, a “multi-screen screening system” according to an embodiment of the present invention will be described.

5 and 6 are exemplary views showing that the multi-screen display system according to the present invention refracts the projection light of a single projection device and selectively projects an image on a plurality of projection surfaces, and FIG. It is an illustration figure which shows the example of a projection light refracting part.
As shown in FIGS. 5 to 7, the multi-screen screening system according to the embodiment of the present invention is configured to project a plurality of projection surfaces 100 that are not parallel to each other and the plurality of projection surfaces. Two or more projection devices 300.
Here, the two or more projection devices include a refraction projection device 310 that refracts the projection light before reaching the projection surface.
In addition, the multi-plane screening system further includes a projection light refracting unit 200 for refracting the projection light of the refractive projection device 310.

  The refracting projection device 310 means a projection device that refracts the projection light projected by itself before reaching the specific projection surface 100. Specifically, the refracting projection apparatus 310 means a projection apparatus 300 that uses refracted projection light to project an image on a projection surface that is arranged so as not to face itself (in a direction other than the front).

Such a refractive projection device 310 refracts its own projection light using various methods, but preferably refracts its own projection light using the projection light refracting unit 200 provided in the traveling direction of the projection light. Let
The projection light refracting unit 200 is a component for refracting the projection light projected by the refractive projection device 310 at various three-dimensional angles.

As shown in FIG. 7, the projection light refraction unit 200 refracts the projection light of the refraction projection device 310. Refraction is realized by various optical devices such as a reflecting mirror 210, a prism 220, a right-angle prism, a regular triangle prism, a pentaprism, and the like. The projection light refracting unit 200 may include, for example, two or more reflecting mirrors 210, two or more prisms 220, and two or more reflecting mirrors 210 and prisms 220.
FIG. 13 is an exemplary diagram showing that the projection light refracting unit according to the present invention includes two or more optical devices. With reference to FIG. 13, an embodiment including a reflecting mirror 210 and a prism 220 will be described.

  The projection light refraction unit 200 is preferably provided in a direction in which the projection light of the refraction projection device 310 travels. The projection light refraction unit 200 is provided, for example, in front of the lamp of the refraction projection device 310, and refracts the projection light emitted from the lamp at this position.

  Meanwhile, the projection light refracting unit 200 is formed so that the main body can move, and changes the angle at which the projection light projected by the refractive projection device 310 is refracted using the movement of the main body. Specifically, the projection light refraction unit 200 is configured to linearly move in a three-dimensional space or to rotate in a three-dimensional space. Using such a linear motion or a rotational motion, the angle at which the projection light projected by the refractive projection device 310 is refracted is changed. Such linear motion or rotational motion is realized by various methods within the technical range obvious to those skilled in the art. For example, it is realized by components such as an actuator, a connection joint, a rail, and a frame whose length can be changed.

  For this reason, the projection light of the refracting projection apparatus 310 can be refracted in various directions in the three-dimensional space by the movement of the projection light refracting unit 200. Thereby, the projection light of the refractive projection apparatus 310 selectively reaches all of the plurality of projection surfaces 100 arranged in various directions in the three-dimensional space. For example, as shown in FIG. 5, the projection light of the refractive projection device 310 selectively reaches the left projection surface or the right projection surface, and is also selected on the upper projection surface or the lower projection surface as shown in FIG. Reach the target. Moreover, in addition to such a projection surface, it is possible to selectively reach various projection surfaces existing inside the theater.

  In short, using the movement of the projection light refracting unit 200, the refracting projection apparatus 310 selectively projects an image on all of the plurality of projection surfaces 100, and thus the refracting projection apparatus 310 is used for a plurality of applications. Be utilized. That is, the refracting projection device 310 uses the operation of refracting the projection light of the refracting projection device 310 to project an image on the left projection surface, to project an image on the right projection surface, and to display an image on the upper projection surface. It is used for various purposes such as projection.

  On the other hand, the main body of the refraction projection apparatus 310 is formed to be movable. Specifically, the main body of the refractive projection apparatus 310 is also formed so as to be capable of linear movement or rotational movement in a three-dimensional space, but by adding such movement of the refractive projection apparatus 310 itself. The refraction angle of the projection light can be changed more variously and accurately.

  The operations of the above-described refraction projection device 310 and the projection light refraction unit 200 are controlled by the management device 400. Specifically, after the management device 400 is electrically connected to the refraction projection device 310 and the projection light refraction unit 200, the operation of the refraction projection device 310 and the operation of the projection light refraction unit 200 are controlled. For example, the management device 400 is connected to an actuator that moves the projection light refracting unit 200 to control the movement of the projection light refracting unit 200, and controls the angle at which the projection light is refracted using the control of such a movement. To do. Further, the management device 400 sends video data to the refractive projection device 310 to control the movement of the refractive projection device 310.

  Also, the management device 400 sends different video data corresponding to the type of the projection surface 100 to which the projection light of the refraction projection device 310 is directed. For example, when the projection light of the refraction projection device 310 is directed to the left projection surface 100, the image data projected to the left projection surface 100 is sent, and the projection light of the refraction projection device 310 is directed to the right projection surface 100. If it is, video data projected on the right projection surface 100 is sent.

  Furthermore, also when projecting images on the upper projection surface 100, the lower projection surface 100, the front projection surface 100, the rear projection surface 100, and the like, the image data projected on each projection surface 100 is sent separately. On the other hand, when the plurality of projection surfaces 100 are formed of different types of projection surfaces, the management device 400 transmits the image data after correcting the video data in consideration of the property difference of the projection surfaces 100 as described above. To do.

Furthermore, the management device 400 controls the operation of the projection light refraction unit 200 in real time based on an external input or the like.
The operation of the projection light refraction unit 200 may be controlled based on data stored in advance in a database (DB). Here, the database stores a plurality of pieces of operation mode information for causing the projection light of the refractive projection device 310 to reach each projection surface 100. For example, the operation angle information such as the arrangement angle of the reflecting surface for refracting the projection light on the left projection surface 100, the position in the three-dimensional space, the operation mode information for refracting the projection light on the right projection surface 100, the upper projection A plurality of operation mode information such as operation information for refracting the projection light on the surface 100 is stored. Therefore, the management device 400 selectively controls the operation of the projection light refracting unit 200 based on the database, and selectively uses the projection light of the refractive projection device 310 to the plurality of projection surfaces 100 based on such control. To reach.

  On the other hand, the projection light refraction unit 200 is provided with a position detection sensor such as a triaxial sensor. For this reason, the management device 400 is connected to such a sensor device and feeds back the operating state of the projection light refracting unit 200 to manage whether the projection light refracting unit 200 is operating normally. Reduce errors related to refraction.

  The refraction projection device 310 is provided with various sensor devices for analyzing performance information. Specifically, the refractive projection apparatus 310 includes a light intensity sensor that detects the light intensity of a lamp that generates projection light, a humidity sensor that detects humidity inside the apparatus, and a temperature sensor that detects temperature inside the apparatus. These sensor devices are connected to the management device 400 and controlled. For this reason, the management apparatus 400 manages maintenance information such as light intensity information, temperature, and humidity of the refractive projection apparatus 310, and manages the performance of the apparatus regarding brightness, failure risk, and the like.

FIG. 8 is an exemplary view showing that the multi-plane screening system according to the present invention includes a plurality of refractive projection apparatuses.
As shown in FIG. 8, the multi-surface screening system according to the embodiment of the present invention includes a plurality of refractive projection devices 310 and a plurality of projection light refraction units 200.
Here, the plurality of refracting projection devices 310 and the plurality of projection light refracting units 200 are preferably 1: 1, and each projection light refracting unit 200 is arranged in the direction in which the projection light of each refracting projection device 310 travels. It is preferable that the projection light of each refractive projection device 310 is provided and refracted.

  The plurality of refracting projection apparatuses 310 and the plurality of projection light refracting units 200 are connected to the management apparatus 400 and are collectively controlled by the management apparatus 400. In this case, the management device 400 controls each projection light refracting unit 200 to control the angle at which the projection light of each refraction projection device 310 is refracted. The projection light is selectively made to reach all of the plurality of projection surfaces 100. Further, the management device 400 associates each refractive projection device 310 and each projection light refraction unit 200 with a plurality of control groups, for example, projection device 1 -projection light refraction unit 1, projection device 2 -projection light refraction unit 2, etc. Control groups are formed, and control operations are performed in units of control groups.

  On the other hand, the management device 400 includes a database (DB) in which information for controlling operations of the plurality of refraction projection devices 310 and the plurality of projection light refraction units 200 is stored, and is stored in such a database (DB). The operations of the plurality of refraction projection devices 310 and the plurality of projection light refraction units 200 are controlled based on the information thus obtained.

FIG. 9 is an exemplary diagram illustrating an example of a database (DB) included in the management apparatus.
With reference to FIG. 9, one embodiment of such a database (DB) will be described. The database (DB) is associated with identification information of each refraction projection device 310 and operation information of each projection light refraction unit 200. Stored in a stored state. The operation information of each projection light refracting unit 200 includes a plurality of operation mode information for selectively refracting the projection light in the direction of the plurality of projection surfaces 100 (for example, the arrangement angle of the reflection surface, three-dimensional Location). For example, the database (DB) stores the identification information of “projection device 1” that is the refractive projection device 310 and the operation information of “projection light refraction unit 1” in association with each other. The operation information of the projection light refraction unit 1 ”includes a plurality of operation mode information.

In particular,
1) “a operation mode” for refracting the projection light of “projection device 1” to “projection surface A”;
2) “b operation mode” for refracting the projection light of “projection device 1” to “projection surface B”;
3) “c operation mode” for refracting the projection light of “projection device 1” to “projection surface C”
A plurality of operation mode information including the above are included.

  Therefore, the management device 400 selectively refracts the projection light of each refracting projection device 310 in the direction of the plurality of projection surfaces 100 based on the information stored in such a database (DB).

  On the other hand, it is preferable that the operation information of the projection light refracting unit 200 stored in the database (DB) is set within a condition in which the projection lights projected by the plurality of refractive projection apparatuses 310 do not overlap. For example, the projection device 1 projects an image on the projection surface A by the projection light refraction unit 1 operating in the a operation mode, and the projection device 2 is adjacent to the projection surface A by the projection light refraction unit 2 operating in the b operation mode. When projecting an image on the projection surface B, a operation mode information (for example, a reflection surface) of the projection light refracting unit 1 within a range in which the image projected by the projection device 1 and the image projected by the projection device 2 do not overlap. And the b operation mode information of the projection light refracting unit 2 are set, and the remaining operation mode information is also set within such conditions.

  Such a multi-surface screening system projects images onto a plurality of projection surfaces 100 using a plurality of refractive projection devices 310. However, in this case, since each refractive projection device 310 selectively projects an image on all of the plurality of projection surfaces 100, the refractive projection device 310 in charge of each projection surface 100 is not determined in advance, and the management device 400 The refraction projection device 310 in charge of each projection surface 100 is changed by the control.

  For example, the plurality of projection surfaces 100 include a projection surface A, a projection surface B, a projection surface C, and a projection surface D, and the plurality of refractive projection devices 310 are the projection device 1, the projection device 2, the projection device 3, and the projection device 4. , The refraction projection device 310 that projects an image on each projection surface 100 is changed under the control of the management device 400.

Specifically, under the control of the management device 400,
1) The projection device 1 projects an image on the projection surface A, the projection device 3 projects an image on the projection surface B, the projection device 4 projects an image on the projection surface C, and the projection device 1 projects on the projection surface D. 2) The projection device 2 projects an image on the projection surface A, the projection device 4 projects an image on the projection surface B, and the projection device 1 projects the image on the projection surface C. Project the image, and the projection apparatus 3 projects the image on the projection plane D. In addition to these, the system has various combinations of “refractive projection apparatus 310-projection plane 100”. Is configured.

  In addition, since such a multi-screen screening system does not require the refraction projection device 310 to be installed in a state of facing the specific projection surface 100, a plurality of refraction projection devices 310 can be freely arranged at various positions in the exhibition hall. be able to. For example, in the multi-screen screening system, the plurality of refracting projection apparatuses 310 are juxtaposed at a specific place, or disposed in a blind spot area or behind the spectator's visual field range. For this reason, the multi-screen screening system can easily manage the refracting projection apparatus 310 by using such an arrangement structure, so that the immersive feeling of the audience can be prevented from being lowered by the projection apparatus 300 existing in the visual field range. .

  On the other hand, such a multi-surface screening system is configured to include a larger number of refractive projection devices 310 than the number of projection devices for projecting images onto the plurality of projection surfaces 100. That is, when the number of projection apparatuses 300 necessary for projecting images on the plurality of projection surfaces 100 is N, the number of the M refraction projection apparatuses 310 is larger than N. Therefore, in such an embodiment, the multi-plane screening system sorts N refraction projection devices 310 according to a predetermined standard among the prepared M refraction projection devices 310, and selects N refractions. An image is projected onto the plurality of projection surfaces 100 using the projection device 310.

  Here, the criteria for selecting the N refraction projection devices 310 used by the multi-screen presentation system for image projection are set based on various information. Preferably, the performance information of each refraction projection device 310, for example, It is preferably set based on light intensity information and maintenance information. This is because the quality of the image projected on the plurality of projection surfaces 100 is ensured by determining based on the performance information of each projection device 300, and the refractive projection device 310 having a performance problem is automatically excluded. .

  In this case, the management apparatus 400 performs the selection operation of the refraction projection apparatus 310 used for performance analysis of each refraction projection apparatus 310 and image projection. Specifically, after the management apparatus 400 analyzes the performance of the M projection apparatuses 300, the N refraction projection apparatuses 310 used for image projection are selected, and the projection light of the selected projection apparatus 300 is refracted. The angle is controlled so that an image is projected on the plurality of projection surfaces 100.

  For example, the management apparatus 400 selects only a refractive projection apparatus having excellent luminous intensity after analyzing the luminous intensity information of each refractive projection apparatus 310. Further, after analyzing the temperature or humidity information inside each refractive projection device 310, the management device 400 excludes refractive projection devices whose internal temperature or humidity exceeds a predetermined reference value. Furthermore, the management apparatus 400 collects resolution information of each refractive projection apparatus 310 and selects only a refractive projection apparatus with a high resolution. Furthermore, the management apparatus 400 collects repair information of each projection apparatus 300 and eliminates refractive projection apparatuses having a large history of repairs due to failures.

FIG. 10 is a conceptual diagram showing that a multi-screen screening system according to the present invention projects an image after selecting a projection device according to a predetermined standard.
Referring to FIG. 10, one embodiment will be described. The management device 400 selects three refractive projection devices 310 (projection devices 1, 3, and 4) out of five refractive projection devices 310 based on performance information. The selected projection device 1 and the corresponding projection light refracting unit 1, the selected projection device 2 and the corresponding projection light refracting unit 2, the selected projection device 4 and the corresponding projection light refracting. The unit 4 is controlled so that images are projected onto the projection surfaces A, B, and C.

  On the other hand, since each of the selected projection light refracting sections has the ability to project an image on the projection surface A, B, or C, the management device 400 is free to use the refracting projection device 310 that projects an image on each projection surface 100. In the embodiment of FIG. 10, the management apparatus 400 controls the image projection operation as 1 → C, 3 → A, 4 → B. For this reason, in this case, the management device 400 sends the video data projected on the projection surface C to the projection device 1, sends the video data projected on the projection surface A to the projection device 3, and the projection surface B to the projection device 4. Send video data to be projected on.
