DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
(First embodiment)
FIG. 1 is a schematic diagram showing a planar configuration of a video display system according to the first embodiment of the present invention, and FIG. 2 is a cross-sectional view taken along line 2-2 in FIG. This video display system includes a projection device 1, a screen 2, a plurality of seats 3, a water mirror (liquid tank) 4, and a ripple generation device 5.
[0013]
Here, the projection device 1 is a projector for projecting a video on the screen 2 based on a video signal sent from a playback device (not shown). Here, the projection device 1 is located above the water mirror 4 at the height of the upper end of the screen 2. It is attached to an attachment member (not shown). However, the present invention is not limited to this, and the projection device 1 may be located above the water mirror 4 or the seat 3 or on the opposite wall surface as long as it is out of the optical path of the direct image and the optical path of the reflected image between the screen 2 and each seat 3. In addition, it may be arranged at any position on the back side of the screen 2 (the side opposite to the seat 3). Although not shown, a plurality of projection apparatuses 1 are arranged so that an image can be projected over the entire area of the screen 2. The video projected by the projection apparatus 1 may be either a moving image or a still image. For example, a CG (computer graphics) video, a slide video such as a picture, and a recorded photo can be used in appropriate combination. It has become.
[0014]
The screen 2 is arranged along the wall surface 6 and displays an image projected from the projection device 1. Although the screen 2 has a concave shape in FIG. 1, it is actually a plurality of screens having a flat plate shape. (Polygonal screen) is arranged along the concave inner wall. However, the screen 2 is not limited to a flat plate shape, and may have a concave shape (circumferential screen) as illustrated.
[0015]
Each seat 3 is disposed on the floor surface 7 so as to face the screen 2, and allows a viewer 8 who is seated or lying down to view the image projected on the screen 2. Arbitrary shapes such as a sofa shape, bench shape, long plate shape (no backrest), and a gravel shape can be used. Needless to say, standing up is acceptable.
[0016]
In FIG. 2, each seat 3 is disposed at a position lower than the lower end portion of the screen 2, but the present invention is not limited to this, and the seat 2 is arranged at a height equal to that of the screen 2. It may be arranged.
[0017]
Further, each seat 3 has only one viewer 8 in FIG. 1, but it goes without saying that a plurality of seats 3 are for seating. Here, the terms “multiple seats” are “multiple seats for one person”, “single seats for multiple persons” and “multiple seats for multiple persons”. The concept including all “thing” is shown, and it may be read as “a seat where a plurality of people can sit”.
[0018]
Further, each seat 3 is not provided with a passage along the radial direction in FIG. 1, but may be provided with a passage through which a person can pass as appropriate. The description of each seat 3 is the same in each embodiment described later.
[0019]
The water mirror 4 is disposed between the screen 2 and the plurality of seats 3 on the floor surface 7 so that the viewers 8 sitting on the respective seats 3 can appreciate the reflected images projected on the screen 2. 8 is a liquid tank having a water surface position lower than the viewpoint position 8 and holding water, and the ripple generating device 5 is arranged at the bottom.
[0020]
In addition, although the shape and dimension of the water mirror 4 are arbitrary and set it as the circular planar shape about 9m-10m in diameter here, in 3rd Embodiment mentioned later, it is set as the rectangle whose short side is about 9m. In addition, the dimension of the water mirror 4 is preferably larger from the viewpoint of providing an immersive feeling. For example, as shown in FIG. 3, the dimensions of the water mirror 4 may be extended to the screen 2 side.
[0021]
In addition, when it is desired to make the reflected image on the water surface and the reflected image on the bottom surface substantially coincide with each other, it is preferable to make the water depth shallower or to provide a screen part for reflection at the shallow water depth portion.
[0022]
In addition, as the color of the inner wall and the bottom of the water mirror 4, any color such as black, blue, or gray can be used. However, when applied to the reflected image as in this embodiment, black, gray, silver, and blue are available. preferable.
[0023]
The water mirror 4 is not limited to a water tank that holds water, but may be a liquid tank that holds another liquid with high reflectivity. Moreover, the water mirror 4 may hold | maintain other members with high reflectance, such as glass or a mirror surface member, in water or a liquid. In the present embodiment, the case where the liquid is water will be described.
[0024]
The ripple generating device 5 is arranged at the bottom of the water mirror 4 and generates ripples by ejecting water toward the water surface weakly according to control from the outside. Here, the term “ripple” may be either single or intermittent for imaging a water droplet and continuous for imaging a ripple.
[0025]
In addition, the ripple production | generation apparatus 5 functions as a fountain apparatus, when the jet pressure of water is high. Similarly, the fountain may be either a normal continuous one or a single or intermittent one for making the image of splash.
[0026]
The ripple generating device 5 uses not only the reflected image on the water mirror 4 but also the characteristics of the indefinite shape of the liquid. From the viewpoint of increasing the production effect, for example, fishermen put water on the water. Control may be performed in conjunction with the image such that the water splashes from the water mirror 4 in synchronization with the image of the effect. However, the ripple generation device 5 may be omitted depending on the contents of the effect. Moreover, it is needless to say that not only the ripple generation device 5 but also a fountain device, a sprayer, a fog generation device using dry ice, various lighting, sound equipment, etc. may be used in combination to increase the effect of rendering the image such as CG. Yes.
[0027]
Next, the operation of the video display system configured as described above will be described.
As shown in FIG. 2 or FIG. 3, the image P projected from the projection device 1 is first displayed on the screen 2. Further, as shown in FIGS. 2 and 4 or FIGS. 3 and 5, the image P projected from the projection device 1 is displayed on the screen 2 and directly viewed by the viewer 8 sitting on the seat 3. As a direct image Pd, the viewer 8 views two reflected images (; upside down images) Pr reflected on the water surface or bottom surface of the water mirror 4.
[0028]
Accordingly, the image on the screen 1 can be directly viewed, and the image on the screen 2 can also be reflected on the water surface or bottom surface, so that the overlapping of the images on the water surface, the depth of the reflected image Pr, the screen surface / water surface・ It is possible to provide a video space where each video on the bottom is woven. In other words, it is possible to appreciate a certain video with different video effects at once. As a result, the viewer can get a sense of immersion in the video and a fantastic sense of the video.
[0029]
In the case of FIG. 3 and FIG. 5, such a video space is a space in which most of the visual field of the viewer 8 is wrapped in video, and an unprecedented video effect can be realized. In addition, it is possible to produce an arbitrary image on the water mirror 4.
[0030]
In addition, by appropriately generating ripples on the water surface of the water mirror 4 using the ripple generation device 5, it is possible to obtain an effect corresponding to the ripples.
[0031]
Subsequently, the appearance of the reflected image Pr will be described in detail with respect to the effect of the direct image Pd, the reflected image Pr, and the ripples as described above.
As shown in FIGS. 6A to 6C, when the water surface of the water mirror 4 is y = 0 and the surface of the screen 2 is x = 0, the viewpoint at the seat 3 in the first row is the viewpoint A ₁ ( x ₁ , y ₁ ). Next, a direct viewpoint A ₁ ′ (x ₁ , −y ₁ ) obtained by inverting the viewpoint A ₁ around the x-axis is obtained, and the bundle of rays 9 emitted from the screen 2 is the direct viewpoint A ₁ ′. Consider a bundle of quadrangular light rays 9 that converge to (x ₁ , -y ₁ ).
[0032]
Next, let us consider a state in which a bundle of quadrangular pyramid rays 9 is folded along the x-axis and the vertex converges to the original viewpoint A ₁ . At this time, the image on the screen 2 is visually recognized by the viewer 8 as a bundle of light rays 9 emitted from the screen 2 and reflected by the water surface of the water mirror 4 to reach the original viewpoint A ₁ .
[0033]
In other words, the reflection image Pr on the water surface is obtained by cutting a bundle of light rays 9 connecting the screen 2 and the direct viewpoint A ₁ ′ along the x axis (line of y = 0), and this cut surface is the original viewpoint A _1. This corresponds to the image Pr viewed from the side.
[0034]
The reflection image Pr in the water surface, as shown in FIG. 7 (a) ~ (c) , when comparing how it was viewing by column number of seats 3, from the viewpoint A ₁ in the first column of the viewer 8 Is viewed as a relatively small image, and as the viewpoints A ₂ , A ₃ ,... Of the viewer 8 away from the water mirror, such as the second row, the third row,. Since it grows larger, it is viewed as a relatively large image.
[0035]
That is, as the viewpoint A moves away from the water surface (that is, moves away in the x-axis direction), the reflected image Pr looks larger, and an image with different expressions can be viewed depending on the distance and angle with the water surface. In addition, as the screen size of the screen 2 is enlarged or reduced, the screen size of the reflected image can be enlarged and reduced for viewing.
[0036]
As described above, according to the present embodiment, the image P from the projection device 1 can be directly viewed as the image Pd projected on the screen 2, and the image P is reflected by the water surface and / or the bottom surface of the water mirror 4. It can be viewed as a reflected image Pr. As described above, when the space including the water mirror 4 is produced, the effect of the production can be improved by reflecting the image on the screen surface on the water surface of the water mirror 4.
[0037]
Supplementally, by reflecting the image on the screen 2 to the water surface, it is possible to obtain an image space in which the overlapping images on the water surface, the sense of depth of the reflected image, and the images on the screen surface, the water surface, and the bottom surface are woven. This video space can produce an unprecedented video presentation effect, and can arbitrarily produce a space with a water surface as the water mirror 4.
[0038]
Further, reflection (reflection) of the image on the surface of the water and fluctuation of the surface of the water can make the viewer 8 feel the water and produce a mysterious and fantastic image due to the indefinite shape of the water. Furthermore, it is possible to develop a fantastic image by using a virtual image (image reflected in the opposite direction) and distortion of the reflected image Pr.
[0039]
Further, since the ripple generator 5 generates ripples on the water surface of the water mirror 4, it is possible to generate an effect produced by the ripples.
By these, for example, it is possible to realize a healing theater in which various images rising from the silent water mirror 4 are viewed. Further, by using the water mirror 4, it is possible to produce a healing space for forgetting the quarrel for a while and enjoying the natural activities nurtured by water. That is, it is possible to preferably realize an effect of quietly enjoying the soft expression of real water, the image reflected in the water, the light, the ripples drawn by the water, etc., rather than the flashy spectacle. In addition, it goes without saying that such healing effects may be performed not only in the theater but also in any facility such as a recreational facility, a break room, or a restaurant.
[0040]
The above effects can be obtained without using special video equipment. On the other hand, in the case of using special video equipment such as a movable projector, in addition to the above effects, when the direct image Pd on the screen surface and the reflected image Pr on the water surface and the bottom surface are linked to each other, a further effect is produced. Can be increased. Such an increase in production effect can be obtained in the same manner when a sprayer or the like is used.
[0041]
(Second Embodiment)

The same reference numerals are assigned and detailed descriptions thereof are omitted, and different parts are mainly described here. In the following embodiments, the same description is omitted.
[0042]
In other words, this embodiment is a modification of the first embodiment, and in addition to the above-described effect, it also realizes an effect when directly projecting an image on a water mirror. , as shown in FIGS. 8 and 9, and a water surface projection apparatus 10 for projecting directly any image P _ov from above the water surface of Mizukagami 4. In FIG. 9, the image of the flower pattern superimposed on the reflected image Pr of the yacht and the seagull is the image P _ov , and this image P _ov may be either a moving image or a still image. The color of the inner wall and the bottom of the water mirror 4 can be any color such as black, blue, or gray. However, when applied directly to the image and the reflected image as in this embodiment, the color is gray, silver, or the like. It is preferable to use any color such as blue or white according to the content of the video. The arbitrary color according to the content of the video means, for example, when the video software includes many images of the sky or the sea, blue used for enhancing the color so that the color looks beautiful.
[0043]
With the configuration described above, in addition to the effects of the first embodiment, the image _Pov projected from the water surface projection device 10 is incident on the water surface of the water mirror 4 and is reflected by the water surface and / or the bottom surface Pr. And the other video _Pov can be appreciated, so that the effect of the video can be further expected.
[0044]
The water surface projection device 10 does not necessarily have to be disposed above the water mirror 4. For example, by projecting an image from an arbitrary position onto a reflection mirror disposed above the water mirror 4, the water mirror 4 is consequently obtained. You may deform | transform so that an image | video may be projected on the surface of water. This modification is also possible in the following corresponding embodiments and modifications.
[0045]
