Description

Single projector multiple projection device theather system}

The present invention relates to a theater system that captures multi-directions with a moving picture capturing apparatus, and edits the images, and multi-directional projections as a single projector multi-directional projection apparatus so that the images can be viewed over 360 degrees.

Currently, most theaters use one projector and one flat screen, and sometimes more than two projectors and curved screens produce more realistic images.

The present inventors conceived that the actual sensitivity would be doubled if the image could be viewed over 360 degrees.

For reference, Patent Application 10-1999-0050515 (Nov. 15, 1999) 'Single Camera Multi-Directional Imager' suggests a theoretical background for collecting multi-directional images with one camera. After fixing, the reflector is inclined at 45 degrees and the image is collected while intermittently rotating at intervals of 90 to 60 degrees by means of 4 to 6 split intermittent rotation means to collect 360-degree images.

In general, multiple projectors are required to project images over 360 degrees.

In order to implement a single projector, it is theoretically possible to rotate the projector body at high speed intermittently. Most projectors are inadequate for high speed intermittent rotation in terms of load and volume and are very difficult to handle wire and communication lines.

The present invention provides various means for projecting images over 360 degree squares with a single projector. More specifically, the present invention relates to a theater system having a device for upright fixing a single projector and projecting the image projected by the projection path changing means onto a screen arranged over 360 degrees.

A theater system utilizing a single projector multidirectional projection device according to the present invention includes a photographing means for photographing multiple directions with a single camera, a recording medium in which multidirectional images are alternately arranged one frame at a time, and the recording medium is converted into a single projector. Single projector for multi-directional projection The projector consists of multi-directional projection means, image display means with a screen adapted to the dividing angle, and audio output means, and the single projector multi-directional projection means is a digital projector or general projector for projecting image frames in detail. It consists of a projection means represented by a projector, and a projection path changing means for projecting an image by dividing 360 degrees forward by a predetermined angle by installing a path of an image projected by a single projection means in the center of the theater.

The present invention mainly relates to a single projector multidirectional projection means and a theater system utilizing the same.

The audience wants to be sucked into the video along with the content while watching the video.

The present invention aims to improve the realism by improving the existing planar screen to 360-degree omnidirectional screen in order to satisfy the needs of the audience. This idea has been around for a long time, but the reality is that it has not been realized due to economic or technical problems.

It is possible to increase the number of projectors, but the present inventors try to solve this problem with one projector and a simple projection path changer.

1A shows a schematic diagram of a typical single projection system theater. It consists of one projector 10, one screen 20 and an audience 30.

1B is a schematic diagram of a projection system theater consisting of three projectors 11. The curved screen 21 has an effect of improving the sensibility of the audience 31 compared to the flat screen 20, but is hardly realized due to technical and economic problems.

Figure 2 shows a schematic diagram of a theater 50 equipped with a six-side screen in one embodiment of the present invention. A high speed projector 71 and a projection changer 90 are provided as the projection means 70 at the center of the theater, and the six-sided screen 60 is provided at the outer 360 degrees.

The audience 32 is seated at the center lower part of the theater 50 to watch 360-degree images. Of course, it is not possible to watch the omni-directional view at the same time because of the human body structure, but if the audience is located on the screen displaying the 360-degree omnidirectional image, the audience will not have enough to cause an illusion as if they were in the location where the image was taken. will be.

If the projection device 70 is a mechanical projector, the mechanical configuration should reinforce durability and robustness as compared to the conventional projection device. This is because N times the film length and N times the projection speed is required to cope with N number of screens. The intermittent rotating mechanism of the projector mainly uses a Geneva cam. For the smooth implementation of the present invention, it is recommended to use an index drive method having excellent movement characteristics. This excellent kinetic property will prevent the wear of the instrument and suppress damage to the film.

The projection path changing device 90 having the reflecting mirror 80 will be described later with reference to FIG.

3 is a schematic view showing a single camera photographing means 110 as an embodiment of the present invention, which is composed of a photographing apparatus 100 and a multi-direction incidence path changing apparatus 111, see patent application 20-1999-0050515. Just do it. If the incident path changing device 111 is a six-part intermittent transfer method, the subject of the area divided by 60 degrees is changed to the incident path through the reflector 120 to be photographed by the photographing apparatus 110.

The projection path changing device of the projection means is almost the same structure as the incident path changing device of the photographing means.

4 shows that the six cameras photographing means 130 is mounted on the body of the photographer 140 as one embodiment of the present invention. The six cameras 131, 132, 133, 134, 135, and 136 capture 360-degree images by dividing 360 degrees into 6-degree images. Images obtained in this way can provide the viewer with the images they see in the location where the photographer is shooting, and the effect will be doubled during simultaneous live broadcasting.

5 illustrates subjects 151, 152, 153, 154, 155, 156 and six photographing apparatuses 131, 132, 133, and 134 in six directions according to one embodiment of the present invention. 135) and the relationship with 136.

The photographer 140 actually photographs the subject 152 in front of the eye, but the 360-degree omnidirectional image is easily obtained by automatically photographing the surrounding 360-degree subjects.

Figure 6a-b is a schematic configuration diagram of the incidence or projection path changing apparatus as an embodiment of the present invention, respectively, showing a front view and a plan view. The driver 170 rotates continuously by the motor 180 and rotates the six-segmented Geneva cam 160 by 60 degrees-stop-60 degrees-rotation-stop, etc. It is to make the intermittent rotation of the method to repeat. The projection or incident image is changed by the reflector or prism attached to the Geneva cam at an inclination of 45 degrees, and is shot with a single photographing device or projected with a single projection device. Or a single projection projector. Normally, a motion picture film should intermittently transfer 24 frames per second. In order to project on a six-segment screen with the same transfer conditions, six divisions * 24 frames = 144 frames must be intermittently transferred. As described above, even if the cost is increased by the intermittent transfer mechanism, an index drive having good movement characteristics may be selected.

Figure 7a-b relates to a film as one embodiment of the present invention. In the case of a mechanical projection apparatus, it corresponds to film, and in the case of image processing using a TV or a computer, it corresponds to an image data channel (frame). FIG. 7A shows photographs of six-way subjects 151, 152, 153, 154, 155, and 156, respectively, and are sequentially edited (151, 152, 153, 154, 155, 156, 151 ', 152', 153 ', 154', 155 ', 156', ...). Indicates. FIG. 7B shows that the projected image is rotated to the right by 60 degrees according to the frame order in order to project the six-side screen. The image taken by the photographing means equipped with the incident path changing means is also incident in the form as shown in FIG. 7B. This is inevitable because the photographing apparatus is fixed upright and the reflector of the incidence path changing means rotates. In other words, the image obtained from the photographing means equipped with the incident path changing device is transmitted to the projection projector, and the projection is fixed upright. The real situation of all directions can be reproduced on the six-side screen simultaneously.

8 shows a configuration diagram of a tuning system circuit 210 of the projection device 70 and the projection path changing device 90. As shown in FIG. Such a technique can be easily implemented by those skilled in the art as a known technique.

9 is a view showing a form in which the multi-directional photographing means 131 is attached to the flight movement means 220 as one embodiment of the present invention, and photographs a subject 360 degrees in the direction of the flight movement means while flying. It can give viewers the feeling that they are on a real plane.

As described above, the multidirectional photographing means includes a combination of a plurality of photographing apparatuses and a photographing means in which the incident path changing device is combined with a single photographing apparatus.

FIG. 10 illustrates a form in which the multidirectional photographing means 132 is attached to a remotely controlled moving means as an embodiment of the present invention, and is useful for photographing the ground or the sea.

Although the present invention focuses on the construction of a theater system, a small theater where two or four people can view 360-degree 360-degree images for home use or a video room may be replaced. It can also be applied to CCTV system construction for security purposes.

An example of the shooting target may be a place of good scenery such as a forest. Artificial wind, snow, or rain can be used to enhance the sense of smell, or it can smell in the forest.

Sightseeing sites will also work. No one will be satisfied with the sights taken by ordinary Camcorders. If the 360-degree image is projected on the screen, the realism will be improved several times and the desired purpose can be achieved without going and seeing.

Sea speed is possible. It is also reasonable to combine them with cartoon films. It can also be adopted for car racing. If the photographing device is further miniaturized, the photographing device is installed between the athletes through the attachment to the athlete's body, and a realistic image can be produced. It can be applied to military or crime prevention. In-pipe shooting is also possible, and the combination of panorama editing techniques provides a more complete image data. Combined with nanotechnology, biometric imaging will be possible.

From this point of view, the current single-plane photography technique can only be replaced by 360-degree omnidirectional imaging technique. The current shooting method only requires a single plane image, so you can see that the assistants perform different types of manipulations around them.

If the subject is a human face and a close-up scene, no matter how many people are around, the shooting operation is easy, but the shooting technique of the present invention does not allow such a shortcut. The 360-degree shots are taken so that neither the photographer nor the supervisor will be visible.

Although this situation may be considered a disadvantage, the present invention will have a lot of influence in view of the production practices, production equipment, production methods, and so on, in view of the fact that it should be shown to the audience as it is. .

The future homework is miniaturization and high function of shooting and projection device, and it is important to connect with existing method and apply computer graphic technology such as panorama editing.

The application of intermittent incidence and projection path changing devices, which can be implemented with low-cost, mid-range technology, can produce a relatively complete 360-degree omnidirectional sensory image, and thus there are many commercial and academic applications. It is expected to be able to erode much of the current single screen TV or theater single screen system, and contribute to the construction of virtual reality, which is a hot topic of this era.
