Even at a ratio of 5 or less, a moving image can be sufficiently displayed. But,
It is preferable for the human eye to determine an image that changes by being divided into 24 or more frames per second as a natural moving image close to the movement of various objects in the natural world.

Next, second to fourth embodiments of the present invention will be described. FIG. 3 is a perspective view showing a light source of the image display device according to the second embodiment of the present invention, and FIG.
It is sectional drawing which shows the XX cross section of the light source of FIG. In the figure, the same reference numerals and symbols as those in the first embodiment denote the same or corresponding parts as in the first embodiment.

In the image display device of the present embodiment, the control of the light source 3 by the light source management means is performed through radio waves.

As shown in FIGS. 3 and 4, the light source 3 of the image display device of the present embodiment has a casing 3 having a shape substantially equal to one part of the egg shell cut at a substantially center in the longitudinal direction.
a, and various components are accommodated in the casing 3a. The casing 3a is made of resin or metal such as plastic, and has a band-shaped shaft member 3b integrally formed at an open end thereof. Shaft member 3b
Is fixed to the suction cup 3h, and the suction surface of the suction cup 3h is
It faces the same direction as the direction of the open end of the casing 3a.
The suction surface of the suction cup 3h projects slightly forward from the open end of the casing 3a. Therefore, the casing 3a is suspended and supported by the suction cup 3h with the open end facing outside by adsorbing the suction cup 3h to the window glass from the inside.

A light bulb 3e is provided inside the casing 3a so as to emit light from the open end.
A reflecting mirror 3f is provided on the back side of the mirror to reflect light from the open end to the outside. A signal processing unit 3c is incorporated between the reflecting mirror 3f and the casing 3a, and a power cord 3d and an antenna 3g drawn out of the casing 3a are connected to the signal processing unit 3c.
The power cord 3d supplies power for emitting light from the light bulb 3e and operating the signal processing unit 3c from an outlet or the like in a room where the light source is installed. The control signal transmitted from the light source management unit via a radio wave is transmitted to the signal processing unit 3c by the antenna 3g. The signal processing unit 3c turns on and off the light bulb 3e according to the control signal sent from the light source management unit.

The plurality of light sources 3 can be independently controlled by one light source managing means. That is, each of the plurality of light sources 3 is assigned an individual address number, and each is controlled by radio waves having different frequencies.

The light source 3 is mounted on the window 2 of the building from the inside as shown in FIG. FIG. 5 is an explanatory diagram showing an installation state of a light source of the image display device according to the second embodiment of the present invention.

At this time, the casing 3a is supported by the suction cup 3h with the open end facing the outside by adsorbing the suction cup 3h to the window glass from the inside, and the light bulb 3e emits light from the open end. Since it is provided, almost all of the light emitted from the bulb 3e is emitted to the outside without illuminating the inside of the room. In particular, since the reflecting mirror 3f is provided on the back side of the bulb 3e, almost all of the light emitted from the bulb 3e is radiated to the outside of the window 2. As described above, the light source 3 is provided with the light condensing means for condensing almost all of the irradiated light to the outside of the window. Therefore, when the window 2 provided with the light source 3 that is emitting light is viewed from the outside, the outline of the light is recognized not as the entire window 2 but as a substantially point-like light having the size of the reflecting mirror 3f. In FIG. 5, four light sources 3 are provided for one window 2. That is, one light source 3 is detachably installed near each of the four corners of the window 2. The power cord 3d drawn from each light source 3 is
The power is supplied to the outlet 6.

The distance between the adjacent light sources 3 is not limited to the distance between the adjacent light sources 3 installed in one window 2 as shown in FIG. 3
Then, if they are limited to only the horizontal direction or only the vertical direction, they are all substantially equal. FIG. 6A is an explanatory diagram illustrating an image displayed by the image display device according to the second embodiment of the present invention.

By turning on only the predetermined light source 3, characters, patterns, etc. can be displayed. FIG. 6A shows that the black light source 3 is on and the white light source 3 is off. The light source 3 that is lit displays characters “KODERA”. Note that the window 2 and the like are not visible in darkness such as at night, so that the window 2 actually looks like FIG. 6B. FIG.

According to FIG. 6B, in darkness such as nighttime, “KODE”
It can be seen that the letters "RA" can be clearly recognized.

Next, the transmission method of the control signal of the image display device of the present invention will be described. FIG. 7 is an explanatory diagram showing a control signal transmission method of the image display device according to the second embodiment of the present invention, and FIG. 8 is a control signal transmission method of the image display device according to the second embodiment of the present invention. FIG. 9 is an explanatory diagram showing another example, and FIG. 9 is an explanatory diagram showing still another example of a control signal transmission method of the image display device according to the second embodiment of the present invention.

The transmission method of the control signal of the image display device shown in FIG.
Are independently transmitted from one light source management unit 4 through radio waves. This method is a wireless light source 3
Is the simplest method, and the equipment cost is the lowest. In particular, since the control signal is transmitted by radio waves, it is possible to install the control signal in a much shorter time than in the case of transmitting the control signal by wire, without the labor and time required for wiring work or the like. Therefore, it is most suitable for advertisement and decoration used only during a certain period such as Christmas and various events. It should be noted that whether or not each light source 3 is controlled normally can be confirmed by actually checking whether the light sources 3 are turned on and off with the naked eye.

The transmission method of the control signal of the image display device shown in FIG.
Each of the signals 3 transmitted from the light source management means 4 to each of the plurality of light sources 3 and transmitted to the light sources 3 as well as being transmitted independently from one light source management means 4 through radio waves.
1 and the signal 32 transmitted from the light source 3 and transmitted to the light source management unit 4 are repeated, and the light source management unit 4 can always check the state of the light source 3. In other words, the light source 3 that has confirmed the signal 31 sent from the light source management unit 4 sends back the signal 32 to the light source management unit 4, but either of the signals has not reached or the power source of the light source 3 is not connected. When a trouble such as the above has occurred, the signal 32 does not return to the light source management unit 4. As a result, the light source 3 can be
Can be controlled. for that reason,
In the adjustment stage immediately after the installation of the light source 3, when there is a light source 3 that is not normally controlled due to a failure to receive a radio wave or a power-off, the light source 3 is located at the light source management unit 4 without going to the installation location. You can keep track of everything. A control signal for turning on and off the light source 3 is transmitted via a signal 31, and a signal for grasping the on / off state of the light source 3 is transmitted via a signal 32.

The transmission method of the control signal of the image display apparatus shown in FIG. 9 is such that a signal transmitted from the light source management means 4 to each of the plurality of light sources 3 and transmitted to the light source 3 and a signal transmitted from the light source 3 The signal transmitted to the light source management unit 4 is repeated, and the light source management unit 4 can always check the state of the light source 3 in the same manner as the control signal transmission method of the image display device shown in FIG. However, the difference is that a repeater 41 is interposed between the light source management means 4 and the light source 3. That is,
A plurality of light sources 3 installed in a predetermined range are connected to a specific repeater 4.
The transmission and reception with the specific repeater 41 are always repeated by receiving the signal 44 from 1 and transmitting the signal 45 at all times. Further, the transmission and reception of the light source 3 installed in another predetermined range with the other repeater 41 are constantly repeated. A plurality of such groups of the repeater 41 and the light source 3 are formed, and the repeaters 41 which take charge of each group independently receive the signal 42 from the light source management unit 4 and send the signal 43 to the light source management unit 4. Thus, transmission and reception with the light source management means 4 are repeated.
Therefore, in the transmission method of the control signal of the image display device shown in FIG. 9, the distance from the light source management unit 4 to the light source 3 may be longer than that of the control signal of the image display device shown in FIG. it can. Therefore, it is possible to control an image of a larger scale than an image which can be controlled by the transmission method of the control signal of the image display device shown in FIG.

The control method of the image display device according to the present embodiment is not necessarily limited to any one shown in FIGS. 7 to 9 and may be partially combined as appropriate according to the application, budget, and the like. Good. For example, even if a part of the light source 3 used in the control method shown in FIG.
9 need not be controlled by the control method of FIG. 9, and the parts that can be controlled by the control method of FIG. 8 are controlled by the control method of FIG. 8, and the parts that cannot be controlled by the control method of FIG. I just need.

As shown in FIG. 9, the number of repeaters 41 interposed between the light source 3 and the light source management means 4 is not necessarily limited to one, but may be plural. In other words, even if the size of the image to be displayed is larger than a predetermined value,
The number of repeaters 41 corresponding to the size of the image to be displayed is interposed between the light source 3 and the light source management unit 4 so that stable signal communication is performed between the light source management unit 4 and the light source 3. Is also good.

As described above, the image display device according to the present embodiment is provided with the light sources 3 removably incorporated near the four corners in each of the windows 2 of the building and the light sources 3. A reflecting mirror 3f, which is a condensing means for condensing almost all of the light emitted from each of the light sources 3 to the outside of the window 2, and a light source for managing each of the light sources 3 via a radio wave and displaying a moving image.

Various types of information are stored, and the management of such information is performed automatically or manually.
Therefore, any of the light sources 3 can be turned on or off regardless of the state of the other light sources 3. Then, a desired image is formed by turning on or off the light source 3 at a predetermined position. If the composed image is changed little by little at a rate of 24 frames or more per second, it is recognized as a natural moving image. However, the pace at which the image is changed does not necessarily have to be 24 frames per second or more, and may be less than 24 frames per second.

However, the transmission of the signal from the light source management means 4 to the light source 3 is performed in the case of the image display device 1 of the first embodiment.
The image display device of the present embodiment is different from the image display device of the present invention in that the image display is performed through a radio wave.
That is, the light source management means 4 of the image display device of the present embodiment is provided internally with transmitters or phase receivers corresponding to the number of light sources 3 independently, and these independent transmitters or phase receivers are provided. , Each light source 3 is controlled.

Therefore, the image display device 1 of the present embodiment
Since a desired image can be displayed by managing the light source 3 incorporated in a part of the plurality of windows 2 of the building by the light source management means 4, the management of the light source 3 is exclusive to each room. It is easier than using lighting equipment of

Further, the light emitted from the light source 33 by the light condensing means concentrates substantially at one point without illuminating the entire window.
Since the light emitting area is much smaller than the area of the entire window and the light emitting position of the light source 3 becomes clearer, if a plurality of light sources 3 are installed in one window, each light source 3 can be recognized independently. Because of the dots, the resolution of the image is improved, and more complex images can be displayed.

In the above description, the number of the light sources 3 provided in the window 2 is four per one window 2, but it is not necessarily limited to four, and the size of the window is not limited to four. The shape, the resolution required for an image to be displayed, the cost, and other conditions may be changed as appropriate. Further, the windows 2 in which the light source is incorporated need not be all the windows 2, and there may be a window 2 in which the light source 3 is not incorporated. If the number of light sources 3 used per unit area increases, higher resolution can be obtained in the displayed image, and conversely, if the number of light sources 3 used per unit area decreases, the cost can be reduced.

In each of the above embodiments, the displayed image on the wall surface of the building is a character, but the displayed image is not necessarily limited to the character, and is displayed on a television screen, a movie screen, or the like. It may be an image that does.

In each of the above embodiments, the present invention can be applied to a window in which glass blocks are combined. In this case, a light source is incorporated in all of the plurality of glass books or in some of the plurality of glass books. By managing each of these light sources with the light source management means, a desired image can be displayed.

Further, in each of the above embodiments, the windows 2 of the building where the image display device is installed are substantially equal in shape, and are arranged at substantially equal intervals in both the vertical and horizontal directions.
The building may not be uniform in the shape and the interval of the windows 2 for use of the building. Even if the shapes and intervals of the windows 2 are irregular and the light sources 3 cannot be arranged uniformly, a desired image can be programmatically displayed by the light source management means 4.
