Description:
CROSS REFERENCE TO RELATED APPLICATIONS 
     This application is a National Stage Entry application of PCT Application No. PCT/JP2018/031873, filed Aug. 29, 2018, which claims the priority benefit of Japanese Patent Application No. JP 2017-233597, filed Dec. 5, 2017, the contents being incorporated herein by reference. 
    
    
     BACKGROUND 
     The present disclosure relates to a ceremonial occasion video display device and a ceremonial occasion building, and particularly relates to a ceremonial occasion video display device and a ceremonial occasion building which can be utilized upon a ceremony for a ceremonial occasion. 
     A ceremonial occasion is a ceremony for reaching an important milestone in a life, and therefore, it has been demanded that the ceremonial occasion is impressive and memorable for people. 
     Typically, in, e.g., a wedding reception, a screen and a projector permanently installed at a wedding center have been utilized to display profile video of the bride and the groom, entertainment video, and end credits, thereby ingeniously planning production in the wedding reception for bringing excitement to the wedding reception (see, e.g., Japanese Patent Publication JP 2008-36097). 
     A ceremonial hall for the ceremonial occasion as described in Japanese Patent Publication JP 2008-36097 includes a ceremonial building body, the screen, the projector, and a stage. Moreover, the screen includes a front screen arranged at a front portion of the ceremonial hall, side screens arranged in parallel at the right and left of the front screen, and an upper screen portion provided on a ceiling. With the above-described configuration, a moving image can be projected onto the multiple screens in the ceremonial hall, and can be provided with a feeling of reality across a wide area in the ceremonial hall. 
     SUMMARY 
     However, in such a ceremonial occasion, production utilizing the screen and the projector has been already broadly known. Thus, even when the moving image is provided across the wide area in the ceremonial hall as in Japanese Patent Publication JP 2008-36097, the feeling of reality is increased because the entirety of the ceremonial hall is surrounded by a large background, but it is hard to say that for the bride, the groom, and attendants, such production is innovative impressive production exceeding prediction and expectation. 
     Moreover, in many cases in the ceremonial occasion, there is much spare time, and the attendants need to kill time at, e.g., a waiting room or a lobby before and after the ceremony or the reception. During such time, video regarding, e.g., information on the bride and the groom is often played. However, it has been already obsolete, and for the attendants, could not be more than the mere way to kill time. 
     The present disclosure has been made in view of the above-described problem, and an object of the present disclosure is to provide a ceremonial occasion video display device and a ceremonial occasion building capable of making more-ingeniously-planned innovative impressive production in a ceremony for a ceremonial occasion. 
     According to a ceremonial occasion video display device of the present disclosure, the above-described problem is solved by a ceremonial occasion video display device used for a ceremonial occasion, the video display device including a display member having a display region for displaying video on a surface and a projection section configured to project the video onto the display region. The display member is in a shape representing an opening book state, and an opening page surface thereof forms the display region. When the video is switched from one moving image to the other moving image, the projection section projects connection video which is a moving image having a predetermined relationship with one moving image projected previously and which indicates contents for previewing the other moving image to be subsequently displayed. 
     Moreover, according to an embodiment of ceremonial occasion building, the above-described problem is solved by a ceremonial occasion building having a room used for a ceremonial occasion, the ceremonial occasion building including a display member having a display region for displaying video on a surface and a projection section configured to project the video onto the display region. The display member is in a shape representing an opening book state, and an opening page surface thereof forms the display region. When the video is switched from one moving image to the other moving image, the projection section projects connection video which is a moving image having a predetermined relationship with one moving image projected previously and which indicates contents for previewing the other moving image to be subsequently displayed. 
     As described above, the video is projected onto the display region of the display member representing the shape of an opening book, and when the video is switched from one moving image to the other moving image, the connection video which is the moving image having the predetermined relationship with one moving image projected previously and which indicates the contents for previewing the other moving image to be subsequently displayed is projected so that highly-entertaining production can be made to entertain a viewer. 
     Thus, in a ceremony for a ceremonial occasion, such as a wedding ceremony, more-ingeniously-planned innovative impressive video production can be made utilizing projection mapping. Particularly, the ceremonial occasion video display device is placed at an attendant&#39;s waiting room or a lobby so that an attendant can spend fulfilling time without killing time even during spare time. 
     Projection mapping described herein is the technique of displaying video as if the video is bonded to a surface of a three-dimensional object instead of a planar screen surface. The three-dimensional object as a screen for displaying the video can be targeted not only for a building but also for any object such as shoes, a table, a chair, a frame, a drawn picture, a human body, a room, a bag, a musical instrument, and a tree. 
     Particularly, in projection mapping for designing and producing a space itself which cannot be produced only with the planar screen surface, powerful video can be produced as if virtual and realistic worlds are mixed, and can captivate the attendant. 
     Moreover, the connection video is the moving image inserted upon switching from one moving image to the other moving image. Specifically, the connection video is the moving image having some kind of association with or continuity to one moving image or the other moving image and including the preview contents for imagining the other moving image to be displayed next one moving image. 
     In this case, the connection video may be for such production that one moving image is turned over from one end of one moving image and the other moving image is displayed on the display region after one moving image has been turned over. 
     As described above, the video is projected onto the display region of the display member representing the shape of the opening book, and when the video is switched from one moving image to the other moving image, the connection video which is for such production that one moving image is turned over from one end of one moving image and the other moving image is displayed on the display region after one moving image has been turned over is projected so that production can be, in combination with the shape of the display member, made as if a page of the book is turned over on the display region of the display member. 
     Thus, in the ceremony for the ceremonial occasion, such as the wedding ceremony, more-ingeniously-planned innovative impressive video production can be made utilizing projection mapping. 
     In this case, the video display device may further include a speaker configured to play predetermined music or a sound effect. The projection section may project the connection video in association with the music or the sound effect. 
     As described above, the video and the music or the sound effect are associated with each other, and for example, the sound effect is played at the timing of projecting the connection video as if the page is turned over. Thus, production with a more feeling of turning over the page of the book can be made. 
     Thus, in the ceremony for the ceremonial occasion, such as the wedding ceremony, more-ingeniously-planned innovative impressive video production can be made utilizing projection mapping. 
     In this case, the video may include a combination of pictures of memories of the bride and the groom or the deceased. 
     As described above, the video to be projected includes the combination of the pictures of the memories of the bride and the groom or the deceased, and therefore, production can be made as if a page of an album of the bride and the groom or the deceased is turned over. 
     Thus, in the ceremony for the ceremonial occasion, such as the wedding ceremony, more-ingeniously-planned innovative impressive video production can be made utilizing projection mapping. 
     According to the ceremonial occasion video display device and the ceremonial occasion building of the present disclosure, more-ingeniously-planned innovative impressive production can be made utilizing, e.g., projection mapping in a ceremony for a ceremonial occasion.

     DETAILED DESCRIPTION 
     Hereinafter, embodiments are described with reference to the figures. 
     An embodiment relates to the technique of a ceremonial occasion video display device including a display member having a display region for displaying video on a surface and representing the shape of an opening book and a projector configured to project the video onto the display region of the display member. Upon projection of the video onto the display member, when the video is switched from one moving image to the other moving image, video which is a moving image having a predetermined relationship with one moving image projected previously and which indicates contents for previewing the other moving image to be subsequently displayed, i.e., connection video for performing such production that one moving image is turned over from one end of one moving image and the other moving image is displayed on the display region after one moving image has been turned over, is projected to perform production as if a page of a book is turned over on the display region of the display member, and relates to the technique of a ceremonial occasion building including the ceremonial occasion video display device. 
     Note that projection mapping is the technique of displaying video as if the video is bonded to a surface of a three-dimensional object such as a building, an object, or a space, and is also called, e.g.,  3 D mapping, video mapping, or architectural mapping. 
       FIG. 1  is a front view of a ceremonial occasion video display device  10 .  FIG. 2  is a schematic illustrative view of the ceremonial occasion video display device  10  from the side. 
     The ceremonial occasion video display device  10  is, for example, placed at a waiting room or a lobby particularly in a building such as a hotel or a wedding house utilized for a wedding ceremony etc. 
     Note that the building in which the ceremonial occasion video display device  10  is placed, such as the hotel or the wedding house, is equivalent to a ceremonial occasion building. 
     As illustrated in  FIGS. 1 and 2 , the ceremonial occasion video display device  10  mainly includes a display member  11  representing the shape of an opening book, a projector  12  configured to project video onto the display member  11 , a speaker  13  configured to play predetermined music or a sound effect, a main body  14  housing the display member  11 , the projector  12 , and the speaker  13  in an internal space, and a transparent glass plate  15  surrounding such that the display member  11  inside the main body  14  is visible from the outside of the main body  14 . 
     The display member  11  is a three-dimensional object representing the shape of the opening book, and a portion forming an upper surface, i.e., an opening page portion, forms a display region  11   a  functioning as a screen for displaying the video. As long as the video can be projected onto the display region  11   a , the detailed shape, size, and material of the display region  11   a  are not limited. In the present embodiment, the display region  11   a  is formed slightly curved for providing the texture of the opening book. 
     The display member  11  is placed on a floor board  16  included in the later-described main body  14 . In this state, the display member  11  is placed with a slightly-forward slope such that the display region  11   a  is easily visible from the front of the ceremonial occasion video display device  10 . 
     The video is projected onto the display region  11   a  of the display member  11  having the above-described configuration by the later-described projector  12 , and in this manner, an atmosphere can be created as if the opening book is viewed. 
     The projector  12  is a projector configured to project the video corresponding to the display region  11   a  onto the display region  11   a  of the display member  11  as in  FIGS. 3 to 6  described below. The video to be projected may be a moving image or a still image. 
     The projector  12  is, in a space above the main body  14 , placed at a position which is not visible from the outside. In the main body  14 , a space in which the display member  11  is placed and a space in which the projector  12  is placed are partitioned by a ceiling board  17 . At a spot exposed to the video projected by the projector  12 , an opening  18  is formed at the ceiling board  17  so that the video can pass through the opening  18 . Note that, e.g., a transparent glass plate may be placed in the opening  18 . 
     The phrase of “project the video corresponding to the display region  11   a ” as described herein includes a meaning that a material (an object) as the video is projected such that the material is bonded to a surface region of the three-dimensional object, i.e., projection mapping is produced. 
     Note that any type of projector  12  can be employed without limitations as long as the projector  12  is a projector capable of producing projection mapping. A light source of the projector  12  may be any light sources such as an LED light source. Moreover, in the present embodiment, the single projector  12  is provided, but multiple projectors  12  can be placed. 
     The speaker  13  is acoustic equipment configured to play the predetermined music or the sound effect in association with the video projected onto the display region  11   a.    
     In an embodiment, the speaker  13  is, as in the projector  12 , placed at a position which is not visible from the outside in the space above the main body  14 , but is not limited to such a position. For example, the speaker  13  can be placed at, e.g., the front or side of the main body  14 . Moreover, multiple speakers  13  can be placed. 
     The main body  14  is a general showcase in which goods such as the display member  11  can be displayed in an internal space. The main body  14  has at least the floor board  16  on which the display member  11  is mounted and the ceiling board  17  configured to divide the space in which the display member  11  is placed and the space in which the projector  12  is placed from each other. At the ceiling board  17 , the opening  18  as a passage for the video projected from the projector  12  is formed. A not-shown decoration with a feeling of depth is added to an outer surface of the main body  14 . 
     Moreover, in an embodiment, the periphery of the display member  11  is surrounded by the transparent glass plate  15  such that, e.g., contact of an attendant&#39;s hand with the display member  11  is prevented. Thus, an attendant can view, through the glass plate  15 , the display member  11  housed inside the main body  14 . Note that the glass plate  15  is not necessarily provided. 
     Next, production contents when the video utilizing projection mapping is projected onto the display region  11   a  is described based on  FIGS. 3 to 6 . 
       FIGS. 3 to 6  are views for describing one example of a state in which video production on the display region  11   a  of the display member  11  by projection mapping is executed by the projector  12 , and the video transitions in the order of  FIGS. 3, 4, 5, and 6 . 
     In  FIG. 3 , pictures of memories of the bride and the groom are, by the projector  12 , projected onto the display region  11   a  of the display member  11  representing the opening book. Specifically, a picture of a sleeping face of the groom when the groom was a baby is displayed on a left page of the opening book (hereinafter referred to as a “first page  21 ”). Moreover, a picture of the groom when the groom was a child is displayed on a right page of the opening book (hereinafter referred to as a “second page  22 ”). 
     Note that as data of the pictures projected herein, data provided in advance from the bride, the groom, and people involved is utilized with the data being stored in a not-shown storage section. 
     As illustrated in  FIG. 4 , a character  25  is projected and appears on the display region  11   a  after a lapse of predetermined time from projection of the video illustrated in  FIG. 3 . The character  25  projected onto the display region  11   a  freely moves around on the right and left pages for a while (not shown), and thereafter, starts such action that the character  25  turns over the second page  22  with the character  25  holding a right end of the second page  22 . 
     On the display region  11   a  after the second page  22  has been turned over, other pictures as next pages are projected as if the character  25  turns over the page of the book. Specifically, part of a third page  23  is projected onto the display region  11   a  at a position on the back side of the second page  22 , and part of a fourth page  24  is projected onto a region after the second page  22  has been turned over. 
     As illustrated in  FIG. 5 , when the character  25  starts such action that the character  25  turns over the second page  22 , the regions of the first page  21  and the second page  22  are gradually narrowed over time, and in proportion to such narrowing, the regions of the third page  23  and the fourth page  24  are subsequently gradually broadened. At this point, the video projected onto the display region  11   a  changes as if the page of the book is turned over. Eventually, the character  25  having taken action for turning over the second page  22  performs such action that the character  25  closes the first page  21  and the second page  22 . 
     Note that the video as illustrated in  FIGS. 4 to 5  is equivalent to connection video. 
     As illustrated in  FIG. 6 , when the character  25  completely finishes turning over the page, the character  25  is temporarily hidden, and a picture of the groom held in mother&#39;s arms is displayed on the third page  23  as the left page of the opening book. Moreover, a picture of a memorable room in which the groom spent his childhood is displayed on the fourth page  24  as the right page of the opening book. 
     Thereafter, the page is turned over one after another, and over time, is switched to a new page on which a different picture is displayed. 
     Moreover, music as BGM matching the atmosphere is, as video production by projection mapping, played from the speaker  13  equipped in the ceremonial occasion video display device  10 . Further, upon video production as illustrated in  FIGS. 4 to 5 , i.e., the video showing that the page is being turned over, the sound effect is accordingly played as if the page is turned over. 
     With this configuration, upon use of the ceremonial occasion video display device  10 , when the attendant views the pictures projected on the display member  11  (the display region  11   a ) in the ceremonial occasion video display device  10 , the attendant has, in combination with the shape of the display member  11  representing the opening book, a feeling as if the attendant opens and views an album of the memories of the bride and the groom. 
     Moreover, by such production that the connection video as illustrated in  FIGS. 4 to 5  is inserted, a state in which the attendant turns over the page to view the album of the memories of the bride and the groom can be faithfully reproduced for the attendant. 
     In the present embodiment, by video production as described above, more-ingeniously-planned innovative impressive production can be made by projection mapping in the wedding ceremony. Particularly, the ceremonial occasion video display device  10  is placed at, e.g., the waiting room or the lobby in a wedding center, and therefore, the attendant can spend fulfilling time without killing time even during spare time before and after the wedding ceremony or reception. 
     A ceremonial occasion video display device and the ceremonial occasion building according to an embodiment have been mainly described. 
     Note that the above-described embodiment is merely one example for the sake of easy understanding, and is not intended to be limiting. For example, in the above-described embodiment, utilization at the wedding ceremony has been described. However, when video production by projection mapping is executed using pictures of memories of the deceased instead of the pictures of the memories of the bride and the groom, the present disclosure can be similarly applied to, e.g., a funeral. 
     Moreover, changes and modifications can be made to the described embodiments without departing from the gist of the present disclosure, and needless to say, the present disclosure includes equivalents thereof.
