The following aspects of the present invention exemplify the configuration of the present invention, and will be described separately for easy understanding of various configurations of the present invention. Each section does not limit the technical scope of the present invention, and some of the components of each section are replaced, deleted, or further while referring to the best mode for carrying out the invention. Those to which the above components are added can also be included in the technical scope of the present invention.

(1) a display unit outer edge is placed on a horizontal surface of a circular, a position overlooking the display unit, the video viewing system and a deployed viewed point so as to form the circular outer edge and concentric.
The video viewing system described in this section includes a display unit having a circular outer edge portion arranged on a horizontal plane, and a viewing point. In this specification, the “viewing point” refers to a range suitable as the position of the viewer's eyes with respect to the display unit in order to obtain an appropriate viewing environment when the viewer views the video displayed on the display unit. ing. The video viewing system described in this section has a reasonable range (height, width), for example, so that the viewing point is concentric with the circular outer edge of the display unit at a position overlooking the display unit. It is arranged in an annular shape. For this reason, for example, in order to create a sense of reality, such as an image of the outer space or the deep sea, a video that does not depend on the viewing direction by the viewer is displayed on the display unit, so that the direction around the concentric axis within the viewing point From any position, the viewer will recognize the video equally. In addition, even if there are multiple viewers, the multiple viewers spread in the direction around the axis with the viewpoint placed in a viewing point that is concentric with the outer edge of the display. Since the video displayed on the display unit is viewed in an attitude of looking down at the unit, an equivalent viewing environment is simultaneously provided to all the plurality of viewers.

(2) In the above item (1), the display unit is a circular plane part, and a curved part that is arranged around the plane part and that defines the circular outer edge part and curves upward toward the outside. A video viewing system in which a boundary between a range in which video is displayed and a range in which the video is not displayed is arranged on the curved portion so as to blur the boundary.
In the video viewing system described in this section, the display unit includes a circular plane part and a curved part arranged around the plane part. The curved portion has a shape curved upward toward the outside, and the outermost edge defines a circular outer edge portion of the display portion. Furthermore, the boundary between the range where the image is displayed and the range where the image is not displayed is arranged on the curved portion so as to blur the boundary, so that such a boundary is visually recognized by the viewer. It will be suppressed. This is particularly effective when displaying images with no corners or edges that image the outer space as the images to be displayed on the display unit, and display more realistic images to viewers. Will be. Furthermore, an image suitable for a flat surface is displayed on the flat surface, and an image suitable for the curved surface is displayed on the curved portion, thereby displaying a realistic image utilizing the shape of the display portion.

(3) In the above item (2), a video viewing system comprising a display floor on which the display unit is installed and a viewing floor on which the viewing point is installed (claim 2).
The video viewing system described in this section includes a display floor on which a display unit is installed and a viewing floor on which a viewing point is installed, so that the display unit and the viewing point are in an appropriate positional relationship in units of floors. Is to be placed. In addition, the display floor is constructed as an environment suitable for installation of the display unit, and the viewing floor is constructed as an environment suitable for video viewing.

(4) The video viewing system according to ( 3), wherein the viewing floor has an opening that is disposed on an upper layer of the display floor and that is concentric with a circular outer edge of the display section. 3).
In the video viewing system described in this section, the viewing floor is arranged above the display floor, and the viewing floor is further provided with an opening that is concentric with the circular outer edge of the display unit. In other words, the display unit is arranged on the lower side of the opening so as to be concentric with the opening. Accordingly, the viewer is prompted to view the video from a viewing point around the opening in a manner of looking down the display unit through the opening. That is, the viewing points are arranged concentrically with the circular outer edge portion of the display portion around the opening provided on the viewing floor. Furthermore, an appropriate distance from the viewing point arranged in the upper layer to the display unit arranged in the lower layer is secured. For this reason, it is suppressed that the viewer viewing from the viewing point recognizes the display surface of the display unit and the dots (pixels) constituting the video. Therefore, it is possible to provide an equivalent viewing environment for the viewer and to display a realistic image with an appropriate resolution.

(5) In the above SL (4) section, the diameter of said opening, wherein the display unit circular outer edge image viewing system that is formed below the diameter of the (claim 4).
In the video viewing system described in this section, the diameter of the opening is formed to be equal to or less than the diameter of the circular outer edge of the display unit, so that the viewing point arranged around the opening is more than the circular outer edge of the display unit. Is also arranged on the central axis side of the concentric circle. Thus, for the viewer who looks down on the display unit through the opening, the circular outer edge portion of the display unit arranged radially outside the opening is intentionally covered by the opening edge protruding in a circular bowl shape. Hidden. The outer edge of the display unit may be a factor that impairs the sense of reality depending on the video to be displayed. However, according to this configuration, it is difficult or impossible for the viewer to recognize the outer edge of the display unit. Therefore, a more realistic video is displayed to the viewer.

(6) In the above items (1) to (5), a video viewing system in which a circular fence is provided along a circular outer edge portion of the display section or a peripheral edge portion of the opening of the viewing floor (claim) Item 5).
The video viewing system described in this section is provided with a circular fence. For example, when the display unit is arranged between the viewing point and the floor of the viewing floor, In the case where the display unit is disposed along the circular outer edge portion or under the opening of the viewing floor, a circular fence is provided along the peripheral edge portion of the opening. Thus, the viewer finds an appropriate viewing point by using the fence as a place. That is, when viewing the video displayed on the display unit, the viewer takes a posture of looking into the display unit through the circular fence from a position along the circular fence. For this reason, even if there are a plurality of viewers, it is possible to prevent other viewers from entering the viewer's field of view and to give the viewers an immersive feeling. Furthermore, by setting the height of the circular fence to be set to a height that takes into account the viewing point, the viewer's viewpoint will be placed naturally when the viewer is in a posture to view the video. In such a range, the arrangement of viewing points is encouraged.

(7) above in (2) (6) section, the curved portion toward the outer side, the video viewing system (Claim 6) inclination angle of the upward gradually increases.
In the video viewing system described in this section, since the upward inclination angle of the curved portion gradually increases toward the outside, the boundary of the display range described in the above section (2) is visually recognized by the viewer. This further suppresses the image from being displayed and displays a more realistic video for the viewer.

(8) The image viewing system comprising at (1) (7) sections of the display device for displaying an image on the display unit (claim 7).
The video viewing system described in this section includes a display device for displaying video on a display unit. Examples of the display device include a configuration including a projector that projects an image on a display unit, and an LED display that displays an image on the display unit itself. Then, by using a display device having an appropriate configuration in consideration of the size and shape of the display unit, video is efficiently displayed on the display unit.

(9) In the above item (8), the display device displays an image in a dot-by-dot manner on the display unit (claim 8 ).
The video viewing system described in this section uses a display device to display video on a display unit dot by dot. Here, “dot-by-dot” is a method in which one pixel of video data reproduced by a reproduction device or the like corresponds to one dot of a device that actually projects or displays an image such as a projector or an LED display. By adopting this dot-by-dot method, video is displayed at the same resolution without adding processing such as enlargement or reduction to the video data, so the video quality is not degraded from the reproduced video data. In addition, an image is displayed on the display unit.

(10) In the above items (8) and (9), the display device displays an image using a projection mapping technique on the bending portion when displaying an image on the display portion ( Claim 9 ).
The video viewing system described in this section displays video using a projection mapping technique on a curved portion of the display unit when the display device displays the video on the display unit. Here, “projection mapping” generally means that the shape of the projection target is used by projecting an image that matches the shape of the projection target when the image is projected by a projection device such as a projector. This is a technology for displaying spatial images. That is, the video viewing system described in this section projects an image that matches the curved shape of the curved portion on the curved portion of the display unit, and displays a spatial video using the curved shape, It is intended to display a more realistic video for the viewer.

(11) In the above items (8) to (10), the display device is configured such that the dot size of the image displayed on the display unit is a viewer's eyes when the viewer views the image from the viewing point. A video viewing system that is less than 1/1000 of a preset viewing distance to the display unit (claim 10 ).
In the video viewing system described in this section, the dot size of the video displayed on the display unit by the display device, that is, the length of one side of one dot of the video is set in advance between the viewer's eyes and the display unit. The viewing distance is set to be 1/1000 or less. For example, when the viewing distance when the viewer views the video from the viewing point is set to 3 m, the dot size of the video displayed on the display unit is 3 mm or less which is 1/1000 of 3 m or less. And This is because the relationship between the distance from the human eye to the image and the dot size of the image is, for example, when the distance is 1 m, the dot size is 1 mm or less, and when the distance is 2 m, the dot size is 2 mm or less. This is based on a judgment criterion that is preferable for production among those skilled in the art that humans do not visually recognize an image in dot units. Accordingly, the viewer viewing from the viewing point is prevented from viewing the video displayed on the display unit in units of dots, thereby giving the viewer a further immersive feeling. Furthermore, since the dot size of the video displayed on the display unit is set based on the viewing distance of the viewer viewing from the viewing point, regardless of the positional relationship between the viewing point and the display unit or the size of the display unit Thus, a video that is always viewed with the same image quality is displayed to a viewer who views from the viewing point.

In the video viewing system described in this section, the display device includes a projector that projects video onto the display unit from above the display unit, and a playback device that provides video data to the projector. Then, the number of projectors included in the display device projects an image composed of the total number of dots calculated based on the size of the display unit and the dot size of the image described in the above item (11) onto the display unit. It is the quantity that can be done. For example, a rectangular area having a size that includes the entire area of the display section that actually displays an image is set from the size of the display section, and this rectangular area is further divided by the dot size described above to obtain the total number of dots. Is calculated. Then, from the calculated total number of dots and the resolution per projector used in the display device, the number of projectors required to project an image composed of the calculated total number of dots is calculated. In the video viewing system described in this section, since the display device includes the projectors calculated in this way, the video that gives the viewer a sense of realism and immersion is efficiently displayed with an appropriate configuration. Will be.

In the video viewing system described in this section, the display device includes one or more projectors that project video onto the display unit from above the display unit, and one or more playback devices that provide video data to the projector. It is a waste. Since the projection area of the projector is usually rectangular, when projecting a circular image on the display unit, the projection area is limited by using the mask function of the projector. If the display unit has a curved surface such as a curved portion, an image using a projection mapping technique is projected onto the curved surface. As a result, an image that gives the viewer a sense of realism and immersion is displayed.

(14) In the above items (12) and (13), the display device includes the same number of the projectors and the playback devices, and the video viewing system in which the projectors and the playback devices are connected on a one-to-one basis. 13 ).

  Further, the video viewing system 10 includes a display device 30 including a configuration as shown in FIG. 3 for displaying video on the display unit 12. The display device 30 includes a plurality of projectors 32 and the same number of playback devices 34 as the projectors 32, and the projectors 32 and the playback devices 34 are connected on a one-to-one basis. As will be described in detail later, the number of projectors 32 and playback devices 32 can be set appropriately according to the video displayed on the display unit 12. 1 and 2, the display device 30 is not shown, and only four projectors 32 that are a part of the configuration are shown in FIG.

  For example, as shown in FIG. 1, the plurality of projectors 32 are installed on the ceiling of the viewing floor 18, and are displayed on the display unit 12 installed on the display floor 16 below the viewing floor 18 from above the display unit 12. An image is projected through the opening 20 of the floor 18. As described above, the display unit 12 has a curved portion 12c that curves upward toward the outside and defines a circular outer edge portion 12a, and the opening 20 of the viewing floor 18 has a diameter thereof. d20 is formed smaller than the diameter d12 of the circular outer edge portion 12a. Therefore, as can be confirmed in FIG. 1, an area in which no image is projected by the projector 32 is generated on the outer edge portion 12a side of the curved portion 12c that is more circular than the boundary line L2. This is because the projector 32 projects an image from above the display unit 12 through the opening 20, so that the projection area is limited by the installation height of the projector 32 and the size of the diameter d20 of the opening 20. This is because it is limited. And since the projection area | region at the time of projecting from upper direction spreads, so that it becomes downward, the boundary line L2 is formed in the larger circle than the circular opening 20. As shown in FIG.

  The plurality of reproduction devices 34 provide reproduced video data to each of the projectors 32 connected in a one-to-one relationship. By using a combination of the playback device 34 and the projector 32 in which the number of output pixels of the playback device 34 and the resolution of the projector 32 are equal, an image based on the video data provided from the playback device 34 can be displayed. 32 is displayed dot-by-dot on the display unit 12. In addition, each of the plurality of playback devices 34 synchronizes and plays back different partial videos of one large video and provides them to each projector 32, thereby combining the videos projected from the plurality of projectors 32, One large image is displayed on the display unit 12.

  Here, the image displayed on the display unit 12 by the display device 30 will be described in more detail. FIG. 4 is an image diagram for explaining an image displayed on the display unit 12. FIG. 4 shows a display in plan view of a display area set in each projector 32 when twelve projectors 32 are used. This is shown together with part 12. In this description, for the sake of convenience, the display areas set for each of the twelve projectors 32 are indicated by reference numerals c1 to c4 and r1 to r3 indicating rows and columns. Specifically, for example, the upper left display area in FIG. 4 is shown as a display area c1r1, the right next display area is shown as a display area c1r2, and the lower right display area in FIG. 4 is shown as a display area c4r3.

  When the display device 30 projects images on the display unit 12 by the twelve projectors 32, as shown in FIG. 4, the display device 30 combines the twelve images projected on the twelve display areas into one large image. indicate. The display areas of the projector 32 are set to rectangles having the same size, and the ends of adjacent display areas are set to overlap. For example, the display area c1r1 has a right end overlapping with the display area c1r2 adjacent to the right, and a lower end overlapping with the lower display area c2r1. The display area c3r2 overlaps with the display areas c2r2, c4r2, c3r1, and c3r3 at the upper, lower, left and right ends, respectively.

  On the other hand, as described above, the outside of the boundary line L2 is an area where no video is projected. Therefore, when an image is actually projected by the projector 32, the image is displayed only in an area inside the boundary line L2 among the display areas set for each projector 32 by using the mask function of the projector 32. Project. Therefore, for example, a region where an image is actually projected by the projector 32 in which the display region c1r1 is set is a substantially fan-shaped region in the display region c1r1 on the lower right side in the drawing with respect to the boundary line L2. In addition, the area where the image is actually projected by the projector 32 in which the display area c1r2 is set has a shape in which one side of the rectangle below the boundary line L2 of the display area c1r2 swells like a bow. It becomes an area. On the other hand, since the display areas c2r2 and c3r2 are entirely inside the boundary line L2, it is necessary to limit the area where an image is projected by the projector 32 in which these two display areas are set by the mask function of the projector 32. Instead, the entire display area is set.

  Then, when the display device 30 projects images with the twelve projectors 32, the projector 32 is located at a position where the display area overlaps inside the boundary line L2 (a portion indicated by hatching in FIG. 4). The image adjusted using the edge blending function is projected. For example, the projector 32 in which the display area c1r1 is set and the projector 32 in which the display area c1r2 is set are adjusted by the edge blending function so that the images projected from each other are in harmony with the overlapping part ar1 of the display area. The projected image. Similarly, the overlapping area ar2 between the display area c1r1 and the display area c2r1 is such that the images are harmonized by the projector 32 in which the display area c1r1 is set and the projector 32 in which the display area c2r1 is set. The image adjusted by the edge blending function is projected onto the screen. In addition, the overlapping part ar3 of the four display areas of the display areas c1r1, c1r2, c2r1, and c2r2 is adjusted by the edge blending function so that the respective images are harmonized by the projector 32 in which each of the four display areas is set. Projected image is projected.

  Further, the display device 30 applies a projection mapping technique to a region inside the boundary line L2 and outside the boundary line L1 (a region indicated by a dot in FIG. 4), that is, a region inside the boundary line L2 of the curved portion 12c. Display the used video. Specifically, out of the 12 projectors 32, the 10 projectors 32 except for the 2 projectors 32 in which the display regions c2r2 and c3r2 are set are within the display region set in each projector 32. An image in harmony with the shape of the bending portion 12c is projected onto the bending portion 12c using a projection mapping technique. At this time, the image projected near the boundary line L2 may be adjusted by the edge blending function to make the boundary between the image display area and the non-display area inconspicuous.

The video viewing system 10 shown in FIGS. 1 and 2 has a structure in which a viewing floor 18 with viewing points 14 is arranged on an upper layer of a display floor 16 with a display unit 12. The video viewing system according to the embodiment of the invention is not limited to this. For example, a structure in which a round table-like display unit is installed at a position slightly higher than the floor surface of the viewing floor without providing a display floor, and a circular fence is provided along the circular outer edge of the display unit may be used. . Even in such a structure, the viewing point is arranged in a range where an appropriate viewing environment can be obtained, and the viewer views the video displayed on the display unit in a manner of looking down the display unit from the viewing point. It will be .

Next, a video display method according to the embodiment of the present invention using the video viewing system 10 described above will be described with reference to the flowchart shown in FIG. In this description, FIGS. 1 to 4 will be referred to as needed.
S10 (Determination of the shape and size of the display unit): The shape and size of the display unit 12 are determined in consideration of the size of the place where the video viewing system 10 is constructed. For example, as shown in FIGS. 1 and 2, the display unit 12 includes a flat portion 12b and a curved portion 12c, and has a circular outer edge portion 12a having a diameter d12.

  S20 (viewing point setting): A viewing point 14 for viewing the video displayed on the display unit 12 is set. For example, as in the example of FIGS. 1 and 2, the viewing point 14 is set based on the viewpoint height of the viewer H standing around the circular fence 22. Further, the height of the circular fence 22 is made lower than that in the example of FIG. 1, and a seat is installed around the circular fence 22, and the viewpoint height of the viewer H sitting on the seat is used as a reference. The viewing point 14 may be set. Here, it is assumed that the viewing point 14 is set at a location relative to the display unit 12 as shown in FIGS.

  S30 (viewing distance setting): A viewing distance serving as a reference when viewing a video from the viewing point 14 is set. FIG. 6 shows an enlarged view near the viewing point 14 of FIG. As shown in the figure, the viewer H sets a viewing distance dv when viewing the video displayed on the display unit 12 from the viewing point 14. The viewing distance dv sets, for example, a vertical distance from the position of the eyes of the viewer H to the flat portion 12b of the display unit 12 when the viewer H looks down the display unit 12 from the viewing point 14. Here, the height of the eyes of the viewer H from the floor surface of the viewing floor 18 is 1.5 m, and the vertical distance from the floor surface of the viewing floor 18 to the flat surface portion 12b of the display unit 12 is 1.5 m. Assume that the distance dv is set to 3 m.

  S40 (Dot size determination): The dot size of the video displayed on the display unit 12 is determined. FIG. 7 is an image diagram showing a part of the video displayed on the display unit 12 in such a size that the dot size can be confirmed. The dot size in this description indicates the vertical and horizontal size x of one dot as shown in FIG. Here, an index for determining the dot size x will be described. In general, it is said that a human with a visual acuity of 1.0 can recognize an object having a size of about 1 mm, which is 3 m away. On the other hand, since the video displayed on the display unit 12 is a video composed of a plurality of dots, the distance from the human eye to the video is used in order not to recognize the boundary of such video dots. Is 1 m or less, when the distance is 2 m, the dot size is 2 mm or less, and when the distance is 3 m, the dot size is 3 mm or less, that is, the dot size is 1000 minutes of the distance. There is a judgment standard (empirical rule) among those skilled in the art that it should be 1 or less. Based on this, the dot size x determined in this step is set to 1/1000 or less of the viewing distance dv set in S30. Here, assuming that the viewing distance dv is set to 3 m, the dot size x is determined to be 3 mm. As a result of intensive studies by the present inventors, even if the dot size x continues to decrease at a value of 1/1000 or less of the viewing distance dv, there is a large difference in the visibility of the boundary of dots by general macroscopic observation. Although it has been confirmed that the image does not appear, considering that the image is composed of dots, the value of the dot size x should be an appropriate value that is larger than 0 and less than 1/1000 of the viewing distance dv. To do.

  S50 (Calculation of the total number of dots in the image): The total number of dots of the image displayed on the display unit 12 is calculated based on the size of the display unit 12 determined in S10 and the dot size x determined in S40. For example, when the diameter d12 (see FIG. 2) of the circular outer edge portion 12a of the display unit 12 is 13 m and the dot size x is 3 mm, the total number of dots of 4334 × 4334 dots or more is displayed on the entire display unit 12. The video can be displayed. Here, for convenience of explanation, the total number of dots of the video displayed on the display unit 12 is assumed to be hn × wn dots shown in FIG.

S60 (Projector quantity calculation): Calculate the quantity of projectors 32 that can project the image composed of the total number of dots calculated in S50 to the display unit 12. At this time, the calculation is performed in consideration of overlapping a part of adjacent display areas of the projector 32. The required number of projectors 32 depends on the number of dots of the image projected by one projector 32, but here, as shown in FIG. 4, an image composed of the total number of dots hn × wn dots is displayed. Assume that twelve projectors 32 are calculated as the number of projectors 32 that can be displayed on the unit 12. When the display device 30 is configured as shown in FIG. 3, since the number of projectors 32 is determined to be 12, the number of playback devices 34 connected to the projector 32 on a one-to-one basis is also increased. 12 units will be decided.
It should be noted that the total number of dots of video projected by the determined number of projectors 32 does not necessarily have to be equal to the total number of dots hn × wn calculated in S50, but may be larger than hn × wn. That is, it is only necessary to project an image with an appropriate total number of dots of hn × wn dots or more according to the resolution of the projector 32 used in the display device 30, the size of overlapping portions between adjacent display areas of the projector 32, and the like.

  S70 (installation of each component): As shown in FIGS. 1 and 2, each component of the video viewing system 10 is installed based on the contents determined in S10 to S60. At this time, for example, the projector 32 or the like may adjust the installation position while actually projecting an image.

  S80 (video display): 12 playback devices 34 perform synchronized playback, and 12 projectors 32 project the synchronized playback video from the top to the display unit 12 to display one large video on the display unit 12. indicate. The image to be displayed is an image composed of the dot size of 3 mm set in S40, and is a circular image in which the display area is limited using the mask function of the projector 32. At this time, a combination of the playback device 34 and the projector 32 in which the number of output pixels of the playback device 34 and the resolution of the projector 32 are equal is used, and the projector 32 and the playback device 34 are connected one-to-one. Thus, the image is projected from the projector 32 without changing the number of pixels from the image reproduced by the reproduction device 34, and the image is displayed on the display unit 12 in a dot-by-dot manner. Further, an image using the projection mapping technique is projected onto the curved portion 12c of the display unit 12, and further, an image adjusted using the edge blending function is projected onto a portion where the display area of the projector 32 overlaps.

  Then, as shown in FIG. 1, the video displayed by the above-described method is viewed by the viewer H standing around the circular fence 22 in a manner of looking down the display unit 12 from the viewing point 14. Examples of the image displayed on the display unit 12 include an image on the theme of space, deep sea, world heritage, and the like. Further, the shape of the display unit may be changed to a shape having a polygonal outer edge such as a hexagon or an octagon according to the theme of the video to be displayed.

  Now, according to the embodiment of the present invention configured as described above, the following operational effects can be obtained. That is, as shown in FIGS. 1 and 2, the video viewing system 10 according to the embodiment of the present invention includes a display unit 12 having a circular outer edge portion 12 a arranged on a horizontal plane, and a viewing point 14. ing. The video viewing system 10 of FIGS. 1 and 2 is arranged in a ring shape so that the viewing point 14 is concentric with the circular outer edge portion 12a of the display unit 12 at a position overlooking the display unit 12. For this reason, for example, when fostering a sense of reality, such as a video image of outer space, a video image that does not depend on the viewing direction by the viewer H is displayed on the display unit 12, so that the concentric circle axis C within the viewing point 14 is displayed. The viewer H can be equally recognized from any position in the surrounding direction. Further, even if there are a plurality of viewers H, the plurality of viewers H is placed in a state where the viewpoint is placed in the viewing point 14 arranged so as to be concentric with the outer edge portion 12a of the display unit 12. Since the video displayed on the display unit 12 is viewed in a posture that spreads in the surrounding direction and looks down on the display unit 12, it is possible to provide an equivalent viewing environment to all the plurality of viewers H at the same time. It becomes possible.

  In addition, the video viewing system 10 includes a display floor 16 on which the display unit 12 is installed and a viewing floor 18 on which the viewing point 14 is installed, so that the display unit 12 and the viewing point 14 can be appropriately arranged on a floor basis. The display floor 16 can be constructed as an environment suitable for installation of the display unit 12, and the viewing floor 18 can be constructed as an environment suitable for video viewing.

  1 and 2, the viewing floor 18 is disposed above the display floor 16, and the viewing floor 18 is provided with an opening 20 that is concentric with the circular outer edge portion 12 a of the display unit 12. It is what has been. In other words, the display unit 12 is arranged concentrically with the opening 20 below the opening 20. Therefore, it is possible to prompt the viewer H to view the video in a manner in which the display unit 12 is looked down through the opening 20 from the viewing point 14 around the opening 20. That is, the viewing point 14 is arranged concentrically with the circular outer edge portion 12 a of the display unit 12 around the opening 20 provided on the viewing floor 18. Furthermore, an appropriate distance from the viewing point 14 arranged in the upper layer to the display unit 12 arranged in the lower layer can be ensured. For this reason, it can suppress that the display surface of the display part 12 and the dot (pixel) which comprises an image | video by the viewer H who watches from the viewing point 14 are recognized. Therefore, it is possible to provide an equivalent viewing environment for the viewer H and display a realistic image with an appropriate resolution.

  Furthermore, the video viewing system 10 according to the embodiment of the present invention is arranged around the opening 20 by forming the diameter d20 of the opening 20 to be equal to or smaller than the diameter d12 of the circular outer edge portion 12a of the display unit 12. The viewing point 14 is arranged closer to the center axis C side of the concentric circle than the circular outer edge portion 12a of the display unit 12. Thereby, the circular outer edge portion 12a of the display unit 12 arranged radially outside the opening 20 with respect to the viewer H looking down at the display unit 12 through the opening 20 opens into a circular bowl shape. It is intentionally obscured by 20b. The outer edge portion 12a of the display unit 12 is a factor that impairs the sense of reality depending on the video to be displayed. However, according to the configuration shown in FIG. 1, the viewer H recognizes the outer edge portion 12a of the display unit 12. Difficult or unrecognizable. Therefore, it is possible to display a more realistic video for the viewer H.

  The video viewing system 10 shown in FIGS. 1 and 2 is provided with a circular fence 22 along the peripheral edge 20 a of the opening 20. As a result, the viewer H finds an appropriate viewing point 14 by using the fence 22 as a place. That is, when viewing the video displayed on the display unit 12, the viewer H takes a posture of looking into the display unit 12 through the circular fence 22 from a position along the circular fence 22. For this reason, even if there are a plurality of viewers H, it is possible to prevent other viewers H from entering the field of view of the viewers H, and to give the viewers an immersive feeling. Furthermore, by setting the height of the circular fence 22 to be set to a height that takes the viewing point 14 into consideration, when the viewer H is in a posture to view the video, the viewpoint of the viewer H is natural. It is possible to prompt the user to place the viewing point 14 in a range where it can be placed on.

Further, in the video viewing system 10, the display unit 12 includes a circular plane part 12b and a curved part 12c arranged around the plane part 12b. The curved portion 12 c has a shape curved upward toward the outside, and the outermost edge thereof defines the circular outer edge portion 12 a of the display unit 12. Further, the boundary L2 between the range in which the video is displayed and the range in which the video is not displayed on the display unit 12 is arranged so as to blur the boundary L2 on the bending unit 12, so that such a boundary L2 is displayed. Can be suppressed from being viewed by the viewer H. This is particularly effective when the image displayed on the display unit 12 is, for example, an image having no corners or edges that imagines outer space or the like, and is more realistic to the viewer H. An image can be displayed. Furthermore, by displaying an image suitable for a plane on the flat surface portion 12b and an image suitable for a curved surface on the curved portion 12c, a realistic image utilizing the shape of the display portion 12 can be displayed. .

  Further, as shown in FIG. 1, the video viewing system 10 is configured such that the upward inclination angle of the bending portion 12 c gradually increases toward the outside, so that the boundary between the video display range and the non-display range is increased. L2 can be further suppressed from being viewed by the viewer H, and a video with a more realistic feeling can be displayed to the viewer H.

  As shown in FIG. 2, the video viewing system 10 is provided with an upward slope 40 for the viewer H to enter the viewing floor 18 and a downward slope 42 for the viewer H to exit the viewing floor 18. It is what has been. Thereby, even if the viewing floor 18 on which the viewing point 14 is installed is provided at a high position, the viewer H can smoothly and easily connect the height difference between the floors with the slopes 40 and 42. You can enter and exit the viewing floor 18. Furthermore, ascending and descending slopes 40 and 42 are provided along a part of the outer periphery of the viewing floor 18, thereby saving space according to the shape of the approach to the viewing floor 18 of the viewer H. Can do.

Further, the video viewing system 10 according to the embodiment of the present invention includes a display device 30 having a configuration as shown in FIG. 3 for displaying video on the display unit 12. By using the display device 30 having an appropriate configuration in consideration of the size and shape of the display unit 12 as the display device 30, an image can be efficiently displayed on the display unit 12.
Furthermore, since the video is displayed dot-by-dot on the display unit 12 using the display device 30, the video can be displayed at the same resolution without adding or reducing the video data. The video can be displayed on the display unit 12 without degrading the video quality from the reproduced video data.

  Further, as shown in FIG. 3, the video viewing system 10 includes a plurality of projectors 32 (see FIG. 1) in which the display device 30 projects an image on the display unit 12 from above the display unit 12, and the projectors 32. The same number of playback devices 34 as the projectors 32 that provide video data are provided, and the projectors 32 and the playback devices 34 are connected on a one-to-one basis. With such a configuration, since video data provided from one playback device 34 is projected from one projector 32, the projector 32 and the playback device 34 are different from each other in a configuration with a different quantity. This makes it easy to manage video data and adjust the projected video. Furthermore, by adopting a configuration in which the number of pixels of video data provided from one playback device 34 and the resolution of one projector 32 match, dot-by-dot display can be easily realized.

  Further, in the video viewing system 10, the display device 30 synchronously reproduces the video with the plurality of playback devices 34, and projects the video from each of the plurality of projectors 32 to the corresponding display area of the display unit 12 set in advance. Thus, a continuous video is displayed on the display unit 12. That is, in each projector 32, for example, display areas for projecting images, such as display areas c1r1 to c4r3 shown in FIG. 4, are set in advance in a part of the display unit 12, and these display areas include a plurality of display areas. When a video is projected from the projector 32 to a plurality of display areas, a continuous video is displayed on the display unit 12. Therefore, even when a video is displayed on the display unit 12 having a large display area, it is possible to display a natural video with a sense of presence using the plurality of projectors 32. As shown in FIG. 4, the display area of the projector 32 is normally rectangular. However, by limiting the display area using the mask function of the projector 32, a circular image can be displayed on the display unit 12. it can.

  Further, when the video viewing system 10 according to the embodiment of the present invention displays a video on the display unit 12 by the projector 32 of the display device 30, as shown in FIG. 4, from the boundary line L2 of the curved portion 12c. Also, an image using a projection mapping technique is projected on the inner side (area indicated by a dot in the figure). That is, by projecting an image that harmonizes with the curved shape of the bending portion 12c onto the bending portion 12c of the display unit 12 and displaying a spatial image using the curved shape, It is possible to display more realistic images.

  Further, when the display device 30 projects images from the plurality of projectors 32, the image viewing system 10 projects the images so that the end portions of the adjacent display areas of the projectors 32 overlap each other. That is, in each projector 32, a display area is set so that the adjacent display areas and ends overlap each other like the display areas c1r1 to c4r3 shown in FIG. Then, the display device 30 projects an image adjusted using the edge blending function of the projector 32 on such an overlapping portion of the display area (area indicated by hatching in the drawing). As a result, a continuous image can be displayed on the display unit 12 and the images displayed in the adjacent display areas can be joined and displayed so that the joints are not conspicuous.

  The video viewing system 10 according to the embodiment of the present invention may be configured such that the display device 30 includes an LED display that constitutes the display unit 12. Thereby, while displaying an image directly on the display unit 12 with an LED display, it is possible to display an image that gives the viewer H a sense of presence or immersion.

  Further, in the video viewing system 10 according to the embodiment of the present invention, the viewing point 14 is optimally preferably in a single row, but may be provided in a plurality of concentric circular rows provided at higher positions on the outer side. It is. For example, when the viewing point 14 is installed on the viewing floor 18, a plurality of annular rows of rows that are higher on the outer side so as to be concentric with the circular outer edge portion 12 a of the display unit 12 are arranged on the viewing floor 18. Provided. Thereby, the viewing point 14 for the viewer H to appropriately view the video displayed on the display unit 12 from each stage is arranged in each of the annular rows. With this configuration, it is possible to provide a viewing environment equivalent to more viewers H at the same time and to the same level of viewers H. In addition, since the distance from the viewing point 14 to the display unit 12 becomes farther toward the outer stage, it is possible to further prevent the viewer H from recognizing the dots that make up the image, and to create a realistic image. It is possible to display.

  On the other hand, the video display method according to the embodiment of the present invention determines the shape and size of the display unit 12 in consideration of the construction location of the video viewing system 10 as shown in FIG. 5 (S10), The viewing point 14 is set at a position that is concentric with the circular outer edge 12a of the display unit 12 (S20). Then, the viewing distance dv (see FIG. 6) between the eyes of the viewer H and the display unit 12 when the viewer H views the video displayed on the display unit 12 is set from the viewing point 14 (see FIG. 6). S30). For example, as shown in FIG. 6, the viewing distance dv is set to a vertical distance from the eye position of the viewer H to the display unit 12 when the viewer H looks down the display unit 12 from the viewing point 14. . Further, based on a judgment criterion preferable for production by those skilled in the art, a dot size x (see FIG. 7) of the image displayed on the display unit 12 having a size of 1/1000 or less of the viewing distance dv is set. (S40). For example, when the viewing distance dv is set to 3 m, the dot size x of the video displayed on the display unit 12 is set to 3 mm or less which is 1/1000 of 3 m or less.

  Then, by displaying the video composed of the dot size x set as described above on the display unit 12 by the display device 30, the video displayed on the display unit 12 is displayed by the viewer H viewing from the viewing point 14. Visibility in units can be suppressed, and a further immersive feeling can be given to the viewer H. Furthermore, since the dot size x of the video displayed on the display unit 12 is set based on the viewing distance dv of the viewer H viewing from the viewing point 14, the positional relationship between the viewing point 14 and the display unit 12, and the display Regardless of the size of the section 12, it is possible to display an image that is always viewed with the same image quality to the viewer H who views from the viewing point 14.

Further, as shown in FIG. 5, the video display method according to the embodiment of the present invention displays on the display unit 12 based on the size of the display unit 12 determined in S10 and the dot size x set in S40. The total number of dots of the video to be calculated is calculated (S50). That is, taking FIG. 4 as an example, the total number of dots hn × wn is calculated when a rectangular area larger than the area inside the boundary line L2 in the display unit 12 is configured with dots of dot size x. .
