DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION This invention is applied to a simulator (Simu
Lator) relates view generating apparatus for use in such, in particular,
The present invention relates to a device for projecting an image by a television system on a screen installed in the front to form a simulated visual field .

[0002]

2. Description of the Related Art Conventionally, a visual image display device for a simulated operation of various moving devices (vehicles, aircraft, ships, spacecrafts, etc.) or an experience device (hereinafter referred to as a simulator) uses a television image. Various types are provided, which are roughly classified to display the field of view directly on the CRT, or a TV projector (Television Pro)
A device for projecting a television image by displaying a jector, a television image on a small liquid crystal screen or the like, and transmitting light from a projector to this screen, or by enlarging and projecting an image from a small CRT with a lens or the like. ) Is used to project on the screen.

The simulator is required to have a field of view as close to reality as possible. A single CRT uses a narrow field of view and a limited shape, which makes it unrealistic. However, the technology of projecting a television image on a screen using a TV projector makes it easy to obtain a large image. Moreover, since it is easy to use the window portion of various simulators as a screen, it is effective as a visual field generator for a simulator.

[0004]

By the way, the field of view in the simulator is not only a large image, but is laterally long and has a curved surface shape surrounding the occupant in order to approximate the actual field of view of the mobile device. Is desired. However, in the field-of-view generator according to the above-described technology, the image from the CRT or TV projector is a television system of NTSC (National Terevison System Commit).
Due to restrictions such as the ee) method, the screen is displayed in a ratio of vertical 3 by horizontal 4. That is, the landscape screen cannot be displayed. This is obvious because, for example, when a screen of a movie having a ratio of length 4 width 6 is reproduced on a television, black bands appear at the top and bottom of the screen. Therefore, in order to obtain a horizontally long field of view, a technique of using a plurality of CRTs or TV projectors to divide and display an image is adopted. In addition, recently, the high-definition system has become widespread, and this has also contributed to the horizontal view (vertical 3
The side 5) can be obtained.

However, in the above-described technique using a plurality of CRTs, in addition to the drawbacks such as the connection points of the divided images being unnatural and the facilities being complicated, the interactivity (simply a pseudo image is displayed). Not only that, it is difficult to have an image that reflects the passenger's intention operation in the image. For example, it is difficult to have the characteristic that the image can be participated in, such as various video games. That is, in order to realize the interactivity, the video signal needs to be processed by the computer, and the display position of the reflected video is determined by the program, hardware, etc. of the computer. Therefore, if it is a divided image, it is necessary to newly develop a dedicated program, hardware, etc.
It is extremely difficult to adopt it in a game simulator, etc., which has a short service life and requires many types.

In the high-definition system, there is no problem due to screen division, but since the amount of information to be handled is large, it is not possible to use software or hardware for the NTSC system, which is easy to perform computer processing. TV for high definition
Since the projector is also specially made, a special program, hardware, etc. must be newly developed, and it is poor in versatility, so that it is difficult to adopt it as a display device such as a game simulator as described above.

In view of the above problems, it is an object of the present invention to provide a field-of-view display device for a simulator, which can obtain a horizontally long field of view with a single TV projector and easily enables interactiveness.

Further, the curved mirror is provided in the projector.
-The curved surface that expands the image projected by
However, the image projected by the projector is laterally compressed.
It can be assumed that it has been subjected to reduction processing.

The television system is a system for converting an image into an electric signal (video signal) and reproducing it.
It means standard system such as C, PAL, SECAM and other special systems, and Projection means forming an image of an object on a screen by using a light source. The image formation means that the entire image projected on the screen is clearly projected, and the screen part means not only the projection screen but also a white surface or a semi-transparent surface that has the same effect as the projection screen. It means a light surface, etc., and includes one integrated with the window part of the simulator. The curved mirror is a mirror having a curved surface, and can be configured by a combination of a straight line portion and a curved surface portion, or a curved surface alone. The compression processing is video processing that expands the vertical or horizontal visual field at the stage of the video signal input to the projection means.The aspect ratio of the video signal is constant, so the video in the direction in which the visual field is expanded is relative. It will be compressed.

[0011] In short, the projector has a projector for projecting a television image on a screen, a curved mirror for magnifying and reflecting by changing the aspect ratio of light from the projector, and a curved screen for focusing the magnified light. Television images were taken by means of the NTSC system.

[0012]

With the above construction, the television image light emitted from the projection means is enlarged and projected in the curved surface direction of the curved mirror, and this image light is projected on the screen which is curved in the enlarged direction. Is imaged. In addition, since the television image is compressed in the direction in which it is enlarged, when it is expanded on the screen, the field of view is enlarged. Television images can be controlled by the NTSC system.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the simulated visual field display device according to the present invention will be described with reference to the drawings. FIG. 1 is a conceptual diagram for explaining the principle and configuration of the simulated field-of-view display device 1. A TV projector 2 projects an image light 4 by a signal from an image reproduction device 3 such as a video tape recorder or a laser disc player. The image light 4 is particularly magnified and reflected by the curved surface portion of the curved mirror 5 and imaged on the screen portion 6. The screen portion 6 is curved so that the image light 4 enlarged (diffused) by the curved mirror 5 can be easily formed.

In FIG. 1, since the curved mirror 5 is curved only in the lateral direction, the screen portion 6 displays an image magnified only in the lateral direction. TV projector 2
It is sufficient to reverse the right and left so that the image light 4 from is a normal image when it is focused on the screen portion 6. Also T
Since the V-projector 2 can be configured as a single unit, it is easy to give the video an interactivity. In this case, various devices (not shown) such as a standard IC board may be appropriately connected.

FIG. 2 illustrates the optical system of FIG. 1 in a plan view, in which the TV projector 2 is installed substantially in the center of the screen portion 6, and the curved mirror 5 is also installed on the center line 8. . Since these optical systems cannot be installed on the same plane, the TV projector 2, the curved mirror 5 and the screen section 6 should be installed at an appropriate angle and vertical line so that the image light 4 is imaged. It is installed with a gap.

FIG. 3 shows an example in which the simulated visual field display device according to the present invention is incorporated into a simulator. The simulator 10 is provided with a simulated visual field display device 15 as a forward visual field of the passenger 12 on the operation console 11. The TV projector 16 projects an image light 17 suitable for the purpose of the simulator 10 and a screen mirror 2 displays an image enlarged in the lateral direction by the curved mirror 18.
Image at 0. The screen 20 is inwardly curved with respect to the passenger 12, and an image appears so as to surround the passenger 12, so that a powerful image can be provided and the simulator 10 can be highly realistic.

FIGS. 4 and 5 respectively explain the change of the aspect ratio of the image and the compression processing of the image by the simulated visual field display device, and FIGS. 4 and 5 both show (a). Is an original drawing, (b) is an image from a TV projector, and (C) is a display image (image formation) on the screen portion. In FIG. 4, in the original drawing 20, a rectangle 21, a circle 22 and a triangle 23 are drawn in a frame of vertical (arrow A direction) 3, horizontal (arrow B direction) 9, that is, 3: 9. (This ratio is a value temporarily set for the sake of explanation.) Here, if the verticals are made to coincide with each other and the television image of the NTSC system, that is, vertical 3: horizontal 4, only the circle 22 like the image 25 is displayed. Fully displayed. An enlarged image 27 is obtained by enlarging the image to make it vertically 3: horizontally 9 and corresponds to a case where a normal television image is displayed by the simulated visual field display device.

FIG. 5 illustrates a video compression process.
Although the effect can be expected in a special image by the enlargement, the visual field is not enlarged, and a natural image cannot be expected. Therefore, the compressed image 28 is obtained by compressing the entire 3: 9 original image into a 3: 4 image. In this case, even if the enlarging process is performed, a natural image in which all of the original image 20 appears, as shown in the high-field image 29. In the high-field video image 29, the resolution in the horizontal direction is naturally lowered, but it has little influence on the moving image used for the simulator and the like, and in the case of an image with a feeling of tension such as the addition of interactiveness, Furthermore, the effect of the high-field-of-view image can sufficiently complement the reduction in resolution. The compression process may be performed by a known means such as an optical process and an electrical process.

FIG. 6 shows another example in which the simulated visual field display device according to the present invention is installed in a simulator, and the simulator 30 has an external curved projection screen 31 incorporated therein. In this case, the image light 17 from the TV projector 16 is projected in the same direction as the visual field of the passenger 12, and the curved mirror 18 is installed so as to face the passenger 12. Image light 1 magnified by the curved mirror 18 here
7 is imaged on the external curved translucent screen 31, but passenger 1
The image viewed by 2 is an image that is semi-transparent to the external music projection screen 31. As a result, the external curved projection screen 31 cannot be installed so as to surround the passenger 12, but
The image light 17 from the V projector 16 can be isolated without the risk of entering the visual field of the passenger 12, and there is no need to reverse the image to the TV projector 16 from side to side.

In addition to the embodiments described above, a CRT is directly used instead of a TV projector, a curved mirror having curved surfaces in both vertical and horizontal directions is used, a curved surface having different curvatures is used, and the installation position of a curved mirror or the like is centered. It is possible to have many variations within the scope of the purpose such as removing from the line, and its application is not limited to the simulator, and it can be applied as a display device in various applications such as household and commercial use. It is a thing.

[0021]

As described above, the simulated visual field display device according to the present invention has at least the following effects.
(1) The television image light emitted from the projection means is
The curved mirror and the curved screen enhances the aspect ratio and enhances the visual effect of the display device. (2)
Since the television image compressed in the enlargement direction can be handled, image distortion does not occur in the enlarged direction, the field of view is enlarged, and the visual effect is further enhanced. (3) Since the aspect ratio can be expanded by a single TV projector, it is not necessary to use a plurality of CRTs, the control is easy, and image division does not occur. (4) Since the aspect ratio can be changed with a simple structure, a fixed price and high reliability can be achieved in improving the visual effect.

According to the second aspect, (5) the visual field is expanded in the lateral direction, and the curved surface of the screen can be installed so as to surround the occupant, so that a more natural simulated visual field can be obtained.
