[0013]

Embodiments of the present invention will be described in detail with reference to the drawings. Note that what is described below is merely one embodiment of the present invention, and the present invention is not limited to this. The first embodiment is an information display device in which projection means is arranged on a ceiling of a stadium, and an information image can be displayed from the projection means using a competition field as a screen. FIG. 1 is a cross-sectional view of a stadium in which the information display device according to the first embodiment is installed. FIG. 1A is a sectional view taken along the line BB (side view), and FIG. 2B is a sectional view taken along the line AA (plan view).

The projection means 30 may be any means capable of forming a visible image on a screen, and is preferably a projection display device (projector) or a laser pointer drawing device, but is not limited thereto. The representative two projection means will be described below in order.

FIG. 3A is an explanatory view of a projection type display device. The projection display device 10 mainly includes a light source 12 for securing the luminance of a visible image, a base image display unit 14 for controlling light from the light source by a base image, and a projection optical system 16 for enlarging and projecting transmitted light. Is done. The base image display section 14 may use a film or the like on which the base image is printed, or may use a liquid crystal panel or the like that forms a base image from the base image data. When a liquid crystal panel or the like is used, the basic image data output device 1 is connected to the basic image display unit via the transmission cable 15.
8 are preferably connected.

One laser pointer drawing apparatus forms a visible image in a field using a laser pointer. FIG. 3B is an explanatory diagram of the laser pointer drawing apparatus. The laser pointer drawing device 20 mainly includes a laser pointer 22 that projects a laser beam, and a laser pointer driving unit 24 that operates the laser pointer according to the design data. It should be noted that simple symbol data can be stored in the laser pointer driving unit. However, when displaying a complicated symbol, a symbol data output device 28 that outputs basic image data to the laser pointer driving unit is separately provided. It is preferable to provide the laser pointer driving section 24 and the transmission cable 25 to connect it to the laser pointer driving section 24.

The projection means as described above is installed above the stadium 2. In the case of a stadium having a ceiling 6 as a whole as shown in FIG. 1, it is preferable to install the projection means on the ceiling vertically above the position on the field 4 where the visible image is to be displayed, but it is not limited to this. . In the case of a stadium that has only a part of the ceiling, a wire rope that extends vertically from the position on the field where the visible image should be displayed, if there is a ceiling, and if there is no ceiling, from another ceiling The projection means is set up for etc. However, when the projection means shakes due to an earthquake or the like, the visible image formed in the field moves and the audience cannot see the information, so it is preferable to fix the projection means as firmly as possible. The positions on the field where the visible image should be displayed are all the audience seats 3
Select an easy-to-view position from. It is preferable to set the center portion of this point field. However, if the portion has irregularities or the color is not uniform, the image becomes rather difficult to see, so other positions can be selected.

On the other hand, the height at which the projection means is installed is not limited in the case of a laser pointer drawing device, but is limited in the case of a projection display device by the light source light quantity and the number of pixels. In the case of a projection display device with a small amount of light source and a small number of pixels, if it is installed at an excessively high position, the brightness and resolution of the visible image displayed on the ground cannot be ensured. Install a display device. It is preferable that the basic image data output device or the design data output device be installed in a control room in a stadium (not shown) and connected to a projection unit installed on a ceiling or the like by a data transmission cable.

The projection means and the data output device installed as described above are connected to an emergency power source such as a private power generator for supplying electric power at the time of a power failure, and necessary for an emergency such as the position of an emergency exit simultaneously with the start of operation of the emergency power source. It is preferable to set the information so that the information can be displayed, but it is not limited to this. In addition, when it is used also for an attraction in normal times, it is connected to a normal power supply.

A method of using the information display device configured as described above will be described below. First, when information necessary for an emergency, such as the position of an emergency exit, is used for displaying to an audience in an emergency, the following procedure is performed.

First, a description will be given of a method of creating a base image when a projection display device is used as the projection means. FIG.
FIG. 1A is an explanatory diagram of a base image creation method when a projection display device is used in the first embodiment. First, a symbol to be displayed is determined. Specifically, it is preferable to use a pattern indicating the position of the emergency exit and the evacuation route as shown in FIG. 1A, but the present invention is not limited to this as long as it is an image in which necessary information is folded in an emergency. Next, the original drawing is photographed by the digital camera 51 or the like as shown in FIG. 1B, and basic image data as shown in FIG. Since the base image is greatly enlarged and displayed in the field, if the number of pixels of the base image data is small, it may be difficult to secure the resolution of the visible image. Therefore, it is preferable to use a digital camera having as many pixels as possible to create base image data having as many pixels. The base image data created in this way is stored in a recording medium and mounted on a base image data output device. The original drawing may be photographed with an analog camera or the like to create a base image film, which may be mounted on a base image display unit of a direct projection display device. Alternatively, the digital data of the original drawing may be directly created on a computer without using a camera, and may be stored in a recording medium as basic image data.

When an earthquake or fire occurs and the stadium loses power and the emergency power supply starts supplying power, power is also supplied to the projection display device and the basic image data output device at the same time. Then, the base image data output device reads the base image data from the recording medium and transmits the base image data to the projection display device through the transmission cable. In the projection type display device, the base image displayed on the base image display unit controls light from the light source, and the projection optical system enlarges the light so that the visible image 19 is displayed on the field as shown in FIG. To project. Still preferably,
At the same time as the projection of the information image by the projection type display device, evacuation guidance or the like based on the announcement in the hall is performed. As a result, it is possible to increase the number of opportunities for the audience to come into contact with necessary information in an emergency. Although the projection of the information image provides information prepared in advance, the announcement in the hall can provide information according to the situation of an emergency. For example, when a part of the emergency exit or the evacuation route indicated by the information image becomes unusable due to the emergency, information on another emergency exit or evacuation route can be provided after broadcasting the fact. Therefore, it is possible to respond flexibly to an emergency and to evacuate the audience quickly.

When a laser pointer drawing device is used as the projection means, it is considered that an image 29 composed of lines is often displayed as shown in FIG. However, at first, only the image 29a is displayed, the images 29a and 29b are displayed at the next moment, and the images 29a, 29b and 29c are displayed at the next moment. In this case, after the symbol is determined, the symbol data to be input to the laser pointer driving unit is created as a function of time and stored in a recording medium. In an emergency, this is output from the symbol data output unit to the laser pointer driving unit through the transmission cable. Then, the laser pointer driving section operates the laser pointer according to the design data, and displays an image on the field by the laser pointer.

By using the information display device according to the present embodiment as described above, information necessary for an emergency, such as the position of an emergency exit, is displayed to spectators at the stadium by a large image formed on the field. You can do it. Therefore, compared to the information display using a small nightlight, a large image can be easily displayed to the audience. Further, compared to the information display by the announcement in the hall, various kinds of information can be displayed to the audience in an easily understandable manner visually. Further, unlike the information display using a signboard or an electronic bulletin board, the information can be displayed in an emergency, which is highly effective. In addition, there is no need to prepare a special screen to use the field where the athlete competes as a screen, and there is no need to prepare a high-power emergency power supply that uses a small amount of power, so that costs are kept low. Can be. Note that when a projection display device is used as the projection means, the displayed image has a limit in luminance, but is displayed during a power failure, so that the audience can view the image sufficiently.
On the other hand, when a laser pointer drawing device is used as the projection means, the image can be given a movement, and the information can be displayed in a more understandable manner.

Next, when the information display device according to the present embodiment is installed at a skating rink or the like and used for exhibition performances or other attractions, or when used as information transmission means during normal times, The procedure is as follows. In the following, a case where a projection display device is used will be described as an example.

Since the visible image formed by the projection display device has a limit in luminance, it is considered that the information display device according to the present embodiment is often used in a situation where the surroundings are dark. Therefore, if the lighting in the stadium is turned off,
That is, it can be used for the performance of exhibitions in figure skating or the like, or for the attraction performed between games. Further, the present invention can also be used to take advantage of the opportunity to display information on a stadium, a sponsor advertisement, and the like. The image to be displayed in that case differs depending on the purpose of the exhibition performance and the attraction, but the method of creating the basic image data and the method of displaying the image itself are the same as those in the above-described emergency. In the future, if a projection-type display device is developed that has sufficient luminance to display an image even in a bright place, it is possible to display a line, a time, and the like for a game. There may be an opportunity to use a moving image. In such a case, basic image data of the moving image is created by a digital video camera or the like and stored in a recording medium. This is reproduced by the basic image data output device, and the basic image data is transmitted to the projection display device one by one. The projection type display device projects this one by one to display a moving image on the field.

At the same time as displaying the visible image, sound such as music can be played in the stadium. For example, a variety of effects can be achieved by playing music or the like suitable for the contents of the image in an exhibition performance, and by playing a sound effect in an attraction. Furthermore, when displaying an image of a stadium guide, a sponsor advertisement, and the like, information such as music can be played at the same time to easily attract the attention of the audience.

By using the information display device according to the present embodiment as described above, exhibition performances and other attractions can be produced in various ways. In particular, when used in a skating rink, a clear image can be displayed since the ice surface is flat and white, and a fine effect can be performed. In addition, by playing music or the like in accordance with the image display, more diverse effects can be produced. On the other hand, also when used as an information transmitting means, various information can be displayed to the audience in an easy-to-understand manner with clear images. In addition, by using the information display device according to the present embodiment not only as an emergency information display device but also as a presentation device as described above, the utilization rate is increased and the device can be easily introduced. By using the device, a failure of the device can be detected at an early stage, and an emergency can be prepared.

In the second embodiment, a plurality of display ranges for the competition field are set, and a plurality of projection means corresponding to the respective display areas are installed on the ceiling of the stadium. Is an information display device provided with control means for connecting the display areas to enable composite display. FIG. 3 shows the second
1 is a cross-sectional view of a stadium in which an information display device according to an embodiment is installed. FIG. 1A is a sectional view taken along line DD (viewed from below), FIG. 2B is a sectional view taken along line EE (viewed from side), and FIG. 3C is a sectional view taken along line CC. (Top view). Note that the configuration of the projection unit is the same as that of the first embodiment, and a description thereof will be omitted.

In the first embodiment, there is only one image display area in the competition field, but in this embodiment, a plurality of image display areas in the competition field are set. The set number and the set position are arbitrary, but preferably, as shown in FIG. 7, in consideration of the image displayable area 60 of each projection unit, an area where an image cannot be displayed by any projection unit on the field occurs. There are no set number and set position. Next, a plurality of projection means 30 are installed on the ceiling 6 of the stadium 2 in accordance with the set number and the set positions of the image display areas. In FIG. 4, the four projection units are arranged evenly, but the invention is not limited to this. Although a plurality of basic image data output devices may be installed corresponding to each projection unit, it is difficult to synchronize each partial image when displaying a moving image. Preferably, the data is output from the device to each projection means. Other installation methods are the same as in the first embodiment.

Next, a control means for connecting a plurality of display areas by the above-mentioned projection means to enable composite display is provided.
FIG. 6 shows a block diagram of the control means. The control means 19
It is composed of a partial image data shaping section 19a, a whole image data dividing section 19b, and a partial image data allocating section 19c. The control means is connected to the base image data output devices 18a and 18b and is installed in a control room in the stadium together with the base image data output devices in order to output the signals to the respective projection means.

The method of using the information display device configured as described above will be described below. First, when information necessary for an emergency, such as the position of an emergency exit, is used for displaying to an audience in an emergency, the following method is used. In addition,
Hereinafter, a case where a projection display device is used will be described as an example.

FIGS. 5 (2) and 5 (3) are illustrations of a method of forming a partial image when a projection type display device is used in the second embodiment. First, an entire image to be displayed is determined. Specifically, it is preferable to use a symbol indicating the position of the emergency exit and the evacuation route as shown in FIGS. (2a) and (3a). However, the symbol is not limited to this symbol if necessary information is inserted in an emergency. .

Next, the whole image is photographed by the digital camera 51 or the like in a plurality of times. In FIG. 2B, 4 corresponds to the number and positions of the projection type display devices shown in FIG.
Shooting is equally divided in several places, but it is not limited to this.
Then, a part overlapping with another partial image is cut off and shaped, and the partial image data 5 as shown in FIG.
Create 4. The shaping and allocation of the partial image data are performed by the control means. First, each partial image data shot as shown in FIG. 5 (2b) is stored in a recording medium after adding the information of the corresponding projection display device, and is controlled by the base image data output device 18a as shown in FIG. Input to means 19. The image displayable area of each projection display device is input to the control means in advance, and the cut-out portion of the partial image data is determined in advance. Based on this, the partial image data shaping section 19a of the control means cuts off the relevant part of the input partial image data. Next, the partial image data allocating unit 19c determines the allocation position of each partial base image data in each projection display device. It is preferable that the layout position is calculated by calculating a coordinate position at which the partial images are combined without gaps when the respective partial images are displayed on the field and the entire image is displayed. Then, after adding the information of the allocation position, each partial image data is output to each projection display device 10.

On the other hand, the entire image may be photographed at a time as shown in FIG. 3B using a digital camera 52 having a larger photographable range and a larger number of pixels than the digital camera 51. In that case, the control means divides the entire image data as shown in FIG. 3C to create partial image data. The division of the whole image data and the allocation of the partial image data are performed by the control means. First, the entire image data captured as shown in FIG. 5 (3b) is stored in a recording medium, and is input to the control means 19 from the basic image data output unit 18b as shown in FIG. The image displayable area of each projection display device is input to the control means in advance. Based on this, the whole image data dividing section 19b of the control means divides the inputted whole image data so that the divided partial images fall within the image displayable area of any one of the projection display devices. Next, the partial image data allocating unit 19c determines the allocation position of each partial base image data in each projection display device. It is preferable that the layout position is calculated by calculating a coordinate position at which the partial images are combined without gaps when the respective partial images are displayed on the field and the entire image is displayed. Then, after adding the information of the allocation position, each partial image data is output to each projection display device 10. Instead of using a camera, the entire image data may be directly created on a computer and input to the control means.

When a power failure occurs in the stadium due to an earthquake or fire, each projection display device displays a partial image on the field as in the case of the first embodiment. At this time, adjacent partial images 54 are combined and displayed without gaps as shown in FIG. 7, and the entire image is displayed large.

When a laser pointer drawing device is used, as in the case of using a projection type display device, first, the entire image data to be displayed is created, and then the divided partial images are displayed. The whole image data is divided so as to enter the image displayable area of the drawing device. Further, each partial image is allocated to each drawing device so that adjacent partial images are combined and displayed on the competition field, and each partial base image data is transmitted to each laser pointer drawing device. Display the whole image on top.
Note that by creating the base image data as a function of time, the display image can be given a movement.
This is the same as the embodiment.

By using the information display device according to this embodiment as described above, a large image can be formed using the entire stadium. This increases the amount of information that can be displayed. For example, even when the emergency exit is at a corner of the stadium, the position can be accurately displayed.
However, if one projection display device is installed at a higher position, an image displayed on the field can be similarly enlarged. However, since each pixel of the projection display device is merely enlarged and displayed, an image becomes difficult to see. In this respect, in the second embodiment, by increasing the number of projection display devices, a large image can be formed without lowering the resolution of the image. As a result, information can be displayed in a more easily understood manner. On the other hand, when the laser pointer drawing device is used, the display image can be given a movement, and the information can be displayed more easily.

Further, even when used for the production of exhibition performances and other attractions during normal times, the amount of information that can be represented by large and precise images increases. Therefore, more various effects can be performed.

【The invention's effect】

The projecting means is arranged on the ceiling of the stadium, and the information field can be displayed on the playing field as a screen from the projecting means. Can be displayed to the audience. In addition, there is no need to install a special screen because the field where the athletes compete is used as a screen, and it is not necessary to use a small amount of power and prepare a high-output power supply, so costs can be kept low. .
