Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a device that simulates the natural environment (images, sounds, temperature) indoors.

(Prior Art) Conventionally, there has been a projection system that projects a movie on the inner wall of a hemispherical dome as a device for artificially reproducing the natural environment (images, sounds) indoors.

An example of this system is the product name ``OMNIMAX'' (IMAX SYS TEMS).
CORPOLATION)". The main components of the projection system include a cinema camera with a fisheye lens, a projector with a fisheye projection lens, and multi-channel audio equipment (amplifiers and speakers).

This is a well-conceived system for photographing an object with a cinema camera through a fisheye lens, then projecting the photographed object back onto the entire inner wall of a hemispherical dome through the fisheye lens of a projector.

When actually projecting a movie using this system,
Do it as follows.

A projector that projects images onto the inner wall of a hemispherical dome, which is the same size as a planetarium, is installed approximately in the center of the dome, multiple speakers are placed appropriately within the dome, and the audience is placed on the flat surface of the hemispherical dome.

There is an example of such a system being released to the public in Japan.

It was opened to the public under the name "Dinorama 360" at the Osaka Castle Exposition (located at Osaka Castle Park, Osaka, sponsored by the Osaka 21st Century Association), which was held from October 1, 1980 to November 30, 1988. It was done.

The size of the dome used for "Dinorama 360" is approximately 12 m in height, approximately 20 m in diameter, and can accommodate approximately 360 people.
It is a dome the size of a person. A fisheye lens projector is installed approximately in the center of the hemispherical dome, and this projector projects movies onto the entire inner wall of the dome. At least four speakers are appropriately arranged on a flat surface inside the dome.

When viewers watch "Dinorama 360," they can feel as if they are actually in the movie scene, which is completely different from watching a movie projected on a conventional flat screen. can be obtained. In other words, you can experience the natural environment (images, sounds) in which the movie was shot in a simulated manner. Depending on the content of the movie, the audience can feel as if they are surrounded by images, or as if something is being placed over their heads. For example, in a skydiving movie, a parachute descends from far above the audience's heads and gradually grows larger, until the audience is completely covered by the parachute that lands on the ground. You can feel the feeling.

However, such a system in which a movie is projected onto the inner wall of the dome using an optical projector has the following drawbacks.

First, the projected movie image is dim. Even if one tries to increase the light intensity of the projection lamp, which is the light source of the projector, in order to make the image brighter, there is a limit to this due to the relationship between the heat emitted from the lamp and the material of the movie film.

Second, there is a drawback that the projected movie image is not sharply focused.

(Purpose of the Invention) The present invention aims to provide a device that simulates the natural environment (images, sounds, temperature) indoors, and in particular, uses an optical projector to project a movie onto the inner wall of a dome. The drawbacks that occur when projecting a movie, that is, the projected movie image is dark,
This device solves the problem of the projected movie images not being sharply focused, and also adjusts the room temperature inside the dome according to the content of the movie, giving the audience a sense of realism that is not available with conventional devices. The purpose is to provide

(Structure of the Invention) A group of video cameras having at least four video cameras that capture images in the horizontal direction and a video camera that captures images in the vertical direction; a transmission means for transmitting output signals from the group of video cameras; a group of means for sending a video signal from the means to a group of light emitting element driving means as a control signal for operating a predetermined group of light emitting elements; an audio reproduction system for reproducing the audio signal from the transmission means; and a group of video cameras. and a temperature regulator that adjusts the temperature of a space in which the light emitting element group is provided according to video content photographed by the environment reproducing device.

(Example) One of the objects of the present invention is that, unlike conventional systems that project movies inside a dome using an optical projector, light emitting elements are closely provided on the entire surface of the inner wall of the dome. The goal is to realize a system that allows you to see the direct light of an LED that shines depending on the brightness of the image, and to provide a device that reproduces images that are brighter than conventional systems and that do not cause out-of-focus images. be.

The main components of the device of the present invention are: an information sensor section A;
It consists of a video camera B, a transmitter C, a system controller D, a video terminal E, an air conditioning system F, and a spherical dome G. H is a communication satellite, and K is a receiving section.

The information sensor section A is a mechanism that senses video, audio, and temperature to be reproduced within the dome G. It consists of an imaging lens with an ultra-wide angle of view and a zoom mechanism to capture images, a microphone to clearly collect audio, and a temperature sensor to detect the temperature at the shooting location.

Video camera B not only reproduces only the video and audio obtained from information sensor section A in dome G via system controller D, but also converts the temperature detected by the temperature sensor into an electrical signal and transmits it to system controller D. Also do what you do.

The system controller D controls the air conditioning system F so that the temperature inside the dome G is the same as the temperature at the shooting site, and is configured so that the information sensor section A can be remotely controlled from there. This system controller D
By providing recording/editing/reproduction means within the device, the above-mentioned transmitted signals can be shifted in time and space or repeatedly reproduced.

The transmitting section C transmits information (video, audio, temperature) from the video camera B to a remote location via the communication satellite H or other suitable transmission means, and the signal sent from the receiving section C is transmitted to a remote location. Information received by the receiving section K is sent to the video terminal section E or the air conditioning system F via the system controller D.

As mentioned above, by using the device of the present invention, the images, sounds, and temperature of the filming site can be reproduced inside the dome, giving the audience inside the dome a sense of realism that is not available with conventional devices. .

FIG. 4 is a diagram showing the state when the video cameras 1A to 1F are set at a shooting site.

FIG. 5 is a plan cross-sectional view showing that LED groups are provided on the inner wall surface of the dome 9.

The main components of an embodiment of the device of the present invention are a video camera 1 (1A to 1F), a video tape recorder (VTR) 2 (2A to 2F), a time base collector (TBC) 3 (3A to 3F), an analog Digital converter (A/D converter) 4 (4A to 4F),
XY address assigner (XY address) 5 (5A~
5F), LED dry drive 6 (6A to 6F), LED group 7 (7A to 7F), sync signal generator 8, dome 9
(9A to 9F), graphic distortion correction circuit 10 (10A
~10F).

The dome 9 on which the image is reproduced is a spherical dome made by combining two conventional hemispherical domes. As will be described later, the image reproduced here is a combination of six images, so in order to show the positions of each of the six divided images, for convenience, the dome 9 is divided into six parts (upper hemisphere dome 9A, upper hemisphere dome 9A, The sphere is divided into four horizontally curved dome parts 9B to 9E and a lower hemisphere dome 9F.

Since the video to be reproduced is a combination of six videos, six playback channels A to F (VTR2A to 2F, TBC3A to 3F,
A/D converter 4A~4F, XY address 5A~5
F, LED driver 6A to 6F, LED group 7A to 7
F) is provided.

Furthermore, the six recording channels A to F (video cameras 1A to 1F, VTRs 2A to 2F, graphic distortion correction circuits 10A to 10F) are the playback channel A.
~F is connected as necessary.

In the following description, since the recording and playback channels A to F have almost the same configuration, the recording and playback channel A will be mainly described, and the other channels will be explained as necessary.

The subject is photographed by six video cameras 1A to 1F. As shown in Figure 4, camera 1A is directed upward, cameras 1B to 1E are directed horizontally, and camera 1F is
The images are taken in the downward direction.

The imaging lenses of the video cameras 1A to 1F have an angle of view of approximately 90° in the horizontal direction and approximately 360° in the vertical direction.

A solid-state image sensor that photoelectrically converts light from an imaging lens is a high-resolution solid-state image sensor that has, for example, 384 horizontal pixels and 485 vertical pixels. As shown in FIG. 3A, the light receiving section 11 of the solid-state image sensor receives a circular optical image 1 through the barrel (not shown) of a cylindrical imaging lens.
2 is imaged.

Video cameras 1A and 1F are equipped with this circular optical image 12
All are converted and output as video signals. As will be described later, the circular optical image 12 is the LED group 7A,
It will be recreated with a large number of LED lights on the 7th floor.

As shown in FIG. 3B, the video cameras 1B to 1E convert and output a square optical image 13 obtained by slicing the circular optical image 12 at a ratio of 4:3 as a video signal. As described later, the angular optical image 13
will be reproduced by a large number of LEDs in LED groups 7B to 7E.

The video cameras 1A to 1F are synchronously coupled by a synchronization signal generator 8 so that they start imaging operations in synchronization.

Since the device of the present invention is a device that reproduces one large image by combining six images, if the images do not connect well, the graphic distortion correction circuit 10A~
The video signal sent from the video camera 1 to the VTR 2 is adjusted in advance so that each image is well connected by adjusting 10F.

The camera 1A outputs information signals (audio signals, video signals) to which various synchronization signals are added, and this information signal is supplied to the VTR 2A and recorded there.

The VTR 2 is composed of a VTR having six information signal tracks corresponding to recording channels A to F, or six VTRs having one information signal track.

The VTRs 2A to 2F are each connected to a synchronizing signal generator 8 so that six information signals are output in synchronization during reproduction.

During playback, the information signal recorded by VTR2A is
The information signal is transmitted to the TBC 3A, where time axis fluctuations in the information signal are corrected.

TBC3A is a semiconductor memory with a capacity that can store information signals for one to two horizontal synchronization signal periods, writes information signals from VTR2A, and reads out already written information signals at the timing of synchronization signal generator 8. . By doing this, the information signal from VTR 2A is transmitted to VTR 2B to 2F.
This allows the TBC3 to output data in complete synchronization with the information signal from the TBC3.

Among the information signals from the TBC 3A, only the video signal is transmitted to the A/D converter 4A, where the analog video signal is sampled at the sampling frequency supplied from the synchronization signal generator 8 and converted into a digital signal. be done.

Among the information signals from TBC3A, audio signals are generated by the sound reproduction system 14, which consists of amplifiers, speakers, etc.
and is reproduced in synchronization with the reproduced video by a speaker (not shown) appropriately provided on the inner wall surface of the dome 9, which will be described later.

The video signal that is the output signal of the A/D converter 4A is
It is supplied to the XY address 5A, where it is sampled at the sampling frequency supplied from the synchronization signal generator 8.

The XY address 5A is the same as when playing images on a cathode ray tube in television.
This video signal is scanned. By this scan
The LED group 7A is sequentially scanned from a predetermined scanning start position, and a large number of LEDs in the LED group 7A are made to blink.
Controls the LED driver 6A.

In this way, the specific LEDs in the LED group 7A (the LED here refers to a set of three red, blue, and green LEDs) blink or darken in sequence, allowing the camera to The video signal sent from 1A is reproduced on the inner wall surface of dome 9A.

The LED groups 7A to 7F are panels in which a large number of LEDs are closely arranged, and are adhered to the inner wall surfaces of the domes 9A to 9F without gaps, as shown in FIG.

Since the LED group 7A (7F) is attached to the wall of the upper hemisphere dome 9A (lower hemisphere dome 9F),
The XY addresses 5A and 5F scan the entire circular optical image 12 described above as a video signal.

Since the LED groups 7B to 7E are pasted on the wall surface of the domes 9B to 9E in four curved shapes in the horizontal direction, the XY addresses 5B to 5E scan all of the aforementioned angular optical images 13 as video signals. be.

By scanning XY address 5A, LED group 7A
The XY controller is configured to cause a specific LED located at the
Address 5A is the LED specified for this video signal.
It is sent to the LED drive circuit in driver 6A.

LED driver 6A selects a specific type in LED group 7A.
This is an LED drive circuit for making LEDs emit light or blink, and the number of drivers is 7A for LED groups.
is the same as the number of LEDs in

The LED driving signal output from the LED driver 6A is provided on the inner wall surface of the dome 9A.
The light is supplied to the LEDs in the LED group 7A, causing the LEDs to emit light according to the gradation and color of the video signal.

The device of the present invention photographs the subject with six cameras,
Since six captured images are combined and reproduced inside the dome 9, the images may not be connected well. At this time, by turning off the LEDs where the differences between the images are noticeable and blurring the discrepancies in the images, the images can be made to a level that is acceptable for practical purposes.

Ring-shaped seats along the inner wall of Dome 9 (not shown)
will be provided.

As mentioned above, the image reproduced by the playback channel A of the device of the present invention is the one in the upward direction of the shooting location, the one in the horizontal direction in the playback channels B to E, and the one in the downward direction in the channel F. It is something.

When the audience views the images reproduced through these playback channels A to F, they can experience a sense of realism as if they were suspended beneath their feet, depending on the content of the movie.

An air conditioner (air conditioner) 15 that adjusts the room temperature inside the dome 9 according to the content of the movie is connected to the synchronization signal generator 8. The synchronization signal generator 8 sends to the air conditioner 15 a control signal for specifying to the air conditioner a temperature to be adjusted in advance depending on the content of the movie.

In order to make the audience immediately feel the temperature change depending on the movie being shown, it would be a good idea to have an air conditioner duct pipe (for heating or cooling) built into the foot of the audience's seat or the back of the seat. .

Although the above-described system assumes a spherical dome for reproducing images, a hemispherical dome may also be used, and in this case, the recording and reproducing channels F may be removed.

(Effects of the Invention) The present invention can provide a device that simulates the natural environment (images, sounds, temperature) indoors, and is particularly capable of projecting a movie on the inner wall of a dome using an optical projector. This eliminates the drawbacks that sometimes occur, such as the projected movie image being dim, the projected movie image not being sharp, and the color of the image blurring, and further improving the content of the movie. By adjusting the room temperature inside the dome according to the situation, it is possible to provide a device that can give the audience a sense of realism that is not available in conventional devices.
