Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image display device for displaying a predetermined image by providing image display means in a visual field area set to cover a viewer.

[0002]

2. Description of the Related Art In recent years, a head mounted display device (hereinafter referred to as an HMD device) shown in FIG. 9A has been used as a device for displaying more realistic images in the fields of game devices, drive simulators, movies and the like. A so-called image display device is known. In this HMD device 200, left-eye and right-eye image display devices such as LCD displays are arranged in front of the viewer's left and right eyes in a game, for example. Then, a visual field region is set so as to cover the visual field of the viewer, and a game image, a movie or the like is displayed on the LCD display to display an image.

According to the HMD device 200, since the visual field area is set so as to cover the visual field of the viewer, it is possible to display an image more realistic than that of an ordinary image display device such as a television. Therefore, the HMD device 200 is most suitable as a game device, an image display device in a driving simulator, an image display device for displaying a movie image, and the like, and commercial and household HMD devices are already on the market.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1A shows a perspective view of this embodiment, and FIG. 1B shows an example of a diorama board 10 which is a diorama image display means. Further, FIG. 2 shows a sectional view of this embodiment. Note that FIG. 1A shows an example of one of the left-eye image display device and the right-eye image display device, but in reality, these left-eye and right-eye image display devices are integrated. It constitutes one image display device.

As shown in FIGS. 1A and 2, in this embodiment, a diorama board 10, an image light reflector 11 and a lens 1 are used.
2, a light guide transparent body 14, an LCD display 16, a light diffusing plate 18, a light source lamp 20, and a light reflecting plate 22.

As a position where the diorama board 10 is arranged, a position on the same plane as the display panel of the LCD display 16 or on the front side of this plane can be considered. In this embodiment, as shown in FIG. The display panel is placed at a position closer to the front than the plane. In addition, FIG. 1 (B)
As shown in, the diorama board 10 according to the present embodiment,
A hole is formed in the effective display area 32, for example, a portion corresponding to the display panel of the LCD display, or this portion is formed of a light transmissive material. This gives L
The image displayed on the CD display 16 can be viewed. Then, the visual field region 30 (the viewer views the lens 12
A predetermined diorama image is displayed in a region which is not the effective display region 32, that is, a region corresponding to the non-effective display region 34, of the region (which can be actually viewed through).
The diorama image in FIG. 1B shows a scene that a viewer can see when he or she actually sees a movie in a movie theater, that is, the curtain of the movie theater, the state of the audience, and the like.

The diorama board 10 can be formed two-dimensionally or three-dimensionally. And as the diorama board 10 formed in a plane,
It is conceivable that a diorama board showing the same picture, photograph, etc. is provided as a diorama board for the left eye and the right eye. Further, in this case, it is possible to obtain a stereoscopic effect to some extent by providing a display such as a picture with a parallax and a photograph as a diorama board for the left eye and a right eye respectively. Further, as the three-dimensionally formed diorama board 10, it is conceivable that three-dimensional objects having the same shape are provided as left and right eye diorama boards, respectively. This makes it possible to obtain a stereoscopic effect due to the depth of focus. Further, in this case, by providing a three-dimensional object with parallax as a diorama board for the left eye and the right eye, it becomes possible to obtain a stereoscopic effect having both parallax and depth of focus.

Now, the lens 12 is used for focusing the image from the viewer on the image displayed on the LCD display 16 or the still image displayed on the diorama board 10. The LCD display 16 displays an actual image such as a game or a movie, and the light source lamp 2 for forming a backlight of the LCD display 16 is provided on the back side of the LCD display 16.
0, the light reflection plate 22 is arranged. That is, by the light generated from the light source lamp 20, directly or by the reflector 2
The light is reflected by 2 and illuminates the display panel from the back side of the LCD display 16. This allows the viewer to see the brightly displayed LCD display image. A light diffusing plate 18 is provided on the back side of the LCD display 16 to prevent light from the light source lamp from escaping.

The light guide transparent body 14 and the image light reflector 11 are
The diorama board 10 is used to display pictures, photographs, etc., or to illuminate and brighten a three-dimensional shape. For example, the light guide transparent body 14 functions to efficiently guide the light of the light source lamp 20 which is the backlight of the LCD display 16 to the diorama board 10. That is, the inner reflection of the light guide transparent body 14 is utilized to uniformly illuminate the back side of the diorama board 10.
Therefore, as shown in FIG. 2, the shape of the light guide transparent body 14 is from the portion near the light source lamp 20 to the diorama board 10.
It is formed so as to extend to a region between the LCD display 16 and the LCD display 16. In this case, the shape of the light guide transparent body 14 is such that the non-effective display area 34 of the diorama board 10 is uniformly illuminated from the back side of the diorama board 10 by the A in FIG.
It is desirable to extend to the part shown by the dot. As a result, the viewer can see the diorama image displayed in the non-effective display area of the diorama board 10, for example, the curtain of the movie theater, the state of the audience seats, etc. under bright illumination.

Further, the image reflection plate 11 is formed of, for example, a plated metal plate having a textured surface or a plated product such as a plastic molded product. And LCD
The light that has passed through the display 16 reflects the light outside the lens 12 to illuminate the front side of the diorama board 10. As a result, the image light of the LCD display 16 is reflected by the image reflection plate 11, so that the diorama image displayed on the diorama board 10 can be seen in a more realistic manner.

According to the present embodiment having the above-mentioned structure, the viewer can see the LCD display 16 displayed in the effective display area 32.
At the same time as viewing the image of, the diorama image displayed in the non-effective display area 34 by the diorama board 10 can be viewed. Therefore, a still image that enhances the atmosphere of the image on the LCD display 16 can be displayed in the non-effective display area 34, which was dark in the HMD device of the conventional example, and the sense of space and the world view can be widened. It is possible to further enhance the effect. Then, in order to effectively show the diorama board 10 to the viewer, the light guide transparent body 14
The light of the light source lamp 20 is guided by or the light transmitted through the LCD display 16 is reflected by the image light reflection plate 11, and the light is guided to the diorama board 10 from the front side.

As described above, according to the present embodiment, the world that can be seen by the viewer is widened even when the LCD display 16 having a narrow angle of view is used. The feeling of being lost disappears. Also LCD
Even if the image displayed on the display 16 is not a three-dimensional image, a sense of depth can be felt. Furthermore, since most of the viewer's visual field can be rendered with a predetermined image, the viewer can fully immerse himself in the world.

Depending on the application, the diorama board 10 can be easily replaced as shown in FIG. 3 (A). As a result, for example, a diorama board 10 formed for movie viewing as shown in FIG.
Can be exchanged for a diorama board 10 formed for a game as shown in FIG. 3 (B). A diorama board for SF games (which has the shape of a cockpit of a spaceship) as shown in FIG. 3B can be used as a diorama board for driving games, for example. In this case, if this diorama board is attached to each game software, the viewer can enjoy the diorama image corresponding to each game, and the added value of the game software can be greatly enhanced.

If a slide film or the like is used as the diorama board 10, it is possible to easily create a diorama with parallax from an actual product. For example, FIG. 1 (B)
Diorama board 1 that shows the scene inside the movie theater, as shown in
0 can be easily created by actually going to the movie theater, shooting a scene in the movie theater with a stereoscopic camera, and using this as a slide film. As described above, when a slide film actually photographed is used as the diorama board 10, the diorama board 10 can be easily created.
In particular, it is the most suitable diorama board used for movie software viewed at home, or as a diorama board used for game software for home-use game machines.

Further, since the LCD display 16 used in a normal HMD device of this type is very small, the number of dots on the display panel is inevitably small. For this reason, it is the current situation that the image displayed on the LCD display 16 cannot be expected to have a very high quality. However, since the diorama board 10 according to the present embodiment can be created, for example, by photographing an actual object with a stereoscopic camera as described above, it is possible to obtain a very precise and high-quality diorama image. In particular, the cockpit in spaceship games, the driver's seat in driving games, etc.
Precise expression is very effective for enhancing the effect of the game, and in this sense, the present embodiment is superior to the conventional example.

Now, the diorama board 1 in this embodiment
As the material forming 0, the following three types can be considered. That is, a light transmissive material, a light reflective material,
And composite types of these.

Here, as the diorama board 10 formed of a light transmissive material, for example, a positive film of a slide or a flat film printed with a transparent ink on a transparent film can be considered. When the diorama board 10 is three-dimensionally formed, a transparent film is printed with transparent ink, and then the diorama board is three-dimensionally processed by thermoforming or a light-transmissive plastic is three-dimensionally formed by injection molding or the like. It is conceivable that the diorama board is formed, or the molded diorama board is colored with a transparent ink.

In these light transmission type diorama boards 10, the light source lamp 2 is made up of the light guide transparent body 14 as described above.
The diorama board 10 can be illuminated by guiding 0 light and irradiating this light from the back side of the diorama board 10. As a result, there is no need to provide a new light source for diorama board illumination, and the device can be downsized.

As the diorama board 10 formed of a light-reflecting material, it is conceivable that the diorama board is formed of a photo, illustration, or printed matter that does not transmit light. Then, as described above, the diorama board 10 can be illuminated by irradiating the light reflected by the image light reflection plate 11 or the like from the front side. As a result, there is no need to provide a new light source for diorama board illumination, and the device can be downsized.

In this light reflection type diorama board 10,
Since it does not transmit light, it is necessary to cut out a hole corresponding to the effective display area of the LCD display 16. As such a light reflection type diorama board 10, a printed matter such as a photograph or a picture can be considered. When the diorama board 10 is formed three-dimensionally,
A three-dimensional object that is three-dimensionally processed by thermoforming after printing on an opaque film, a three-dimensionally molded opaque plastic by injection molding, or a colored product of this molded article is considered. In the light-reflective diorama board 10, when an enemy spaceship explodes, for example, in a game, the cockpit 4 is displayed in the color of the exploding light.
2 will be illuminated, which has the advantage that the staging effect can be greatly enhanced.

As the diorama board 10 of these light transmission type and light reflection type, for example, the diorama board 1 is used.
It is conceivable that a predetermined portion of 0 is formed of a light transmission type material and the other portions are formed of a light reflection type material. A diorama board 10 having such a configuration is shown in FIG.
When used in the diorama board 10 for SF games shown in (B), the following unique effects are obtained. That is, FIG.
In the diorama board 10 shown in (B), the instrument 44 and the like in the cockpit 42 are formed of a light transmissive material, and the other portions are formed of a light reflective material. In this way, if the spacecraft is flying in the dark, LC
The display screen of the D display 16 becomes dark. Therefore, the reflected light formed by reflecting the light from this display screen by the image light reflection plate 11 becomes weak, and as a result, the cock bit 42 illuminated by this reflected light is displayed dark. On the other hand, the light from the light source lamp 20 is directly radiated from the back side to the portion formed of the light transmissive material such as the instrument 44 through the light guide transparent body 14. Therefore, these instruments 44 and the like are always illuminated brightly. As a result, when flying in the darkness, only the instrument 44 and the like can be made to shine brightly, and the realism of the game can be greatly enhanced. In this case, in particular, by coloring the light-transmitting material of the instrument 44 with a transparent ink or the like, the instrument 44 can be made to shine in colors such as red and blue, and the effect of producing an image can be further enhanced.

Next, stereoscopic vision on the diorama board 10 will be described. There are the following four types of stereoscopic vision in the diorama board 10. That is, a parallax-free flat diorama board, a parallax-free flat diorama board, a parallax-free three-dimensional diorama board, and a parallax three-dimensional diorama board.

The parallax-free flat diorama board represents the display of pictures, photographs, etc. on the diorama board 10 in a two-dimensional manner. The diorama board for the left eye and the diorama board for the right eye are displayed. They are the same.

In this case, the same pictures, photographs, etc. are only displayed side by side, and the pictures, photographs, etc. display itself does not have a stereoscopic effect or a sense of depth. However, since the difference in the sense of distance from the screen of the LCD display 16 can be expressed by shifting these displays to the left or right, a sense of depth with respect to the LCD screen can be expressed, which is very effective for some applications.

The plane diorama board with parallax is a plane view for displaying pictures, photographs, etc. on the diorama board 10. The diorama board for the left eye and the display on the diorama board for the right eye are used. There is a parallax between them.

As such a plane diorama board with parallax, an actual object photographed by a camera having parallax for the right eye and the left eye, created by computer graphics, or drawn by calculating parallax You can think of a flat material that can be viewed stereoscopically, such as an illustration, created with consideration for the left and right parallax. The plane diorama board with parallax differs from the plane diorama board without parallax described above in that a stereoscopic effect due to parallax occurs in the display of pictures, photographs and the like displayed on the diorama board. Therefore, it is possible to expect an expression with a real feeling and a real feeling. Moreover, the plane diorama board with parallax has a great advantage that it can be very easily produced by using a stereoscopic camera or the like as described above.

As described above, the plane diorama board with parallax enables very excellent stereoscopic expression. However, although parallax is provided in the display of pictures, photographs, etc. displayed on the left and right diorama boards, these displays are not physically three-dimensionally formed. Therefore, although the depth and stereoscopic effects due to the parallax occur, the depth and stereoscopic effects due to the focus depth do not occur. Here, the depth sensation and stereoscopic effect due to the focus depth refer to the depth sensation and stereoscopic effect that the viewer feels by focusing on the target object. In the parallax plane diorama board, the display of pictures, photographs, etc. displayed on the diorama board and the focus depth of the LCD screen can be made infinite by the lens 12, for example. Therefore, it is suitable for a diorama board or the like showing a scene of a movie theater as shown in FIG.

The parallax-free three-dimensional diorama board is a diorama board 10 having a three-dimensional shape in which the diorama board for the left eye and the diorama board for the right eye have the same shape. is there.

In this case, only three-dimensional objects having the same shape are lined up, and there is no sense of depth or stereoscopic effect due to parallax. However, since the shape is three-dimensionally represented, a depth feeling and a three-dimensional effect are generated due to the depth of focus, and a stereoscopic viewing can be performed with a natural feeling.
With this parallax-free stereo diorama board, it is possible to obtain a stereoscopic effect to some extent even if one eye is closed. In particular, as shown in FIG. 4 (A), by disposing the diorama boards 10a and 10b for the left eye and the right eye slightly inclined inward, it is not accurate, but parallax occurs,
This enables a very good stereoscopic view.

The three-dimensional diorama board with parallax represents a three-dimensional shape on the diorama board 10, and a parallax is provided between the shape shown on the diorama board for the left eye and the shape shown on the diorama board for the right eye. It is a thing.

Such a stereoscopic diorama board with parallax is difficult to manufacture, but by suppressing the depth direction, a large stereoscopic effect can be expressed with a compact model, and perfect parallax and perfect focus depth can be achieved. It becomes possible to express.

Next, a method of forming a stereoscopic diorama board with parallax having an accurate focus depth will be described. Normally, in this kind of HMD device, the LCD is provided by the lens 12.
The focus depth of the display 16 is set to infinity or slightly in front of it (about 10 m). It is assumed that the actual distance from the viewer's eyes 2 to the lens 12 is 3 cm, and the actual distance from the lens 12 to the LCD display 16 is 4 cm, as shown in FIG. 4B. If the lens 12 is designed so that the focus depth of the LCD display 16 is 10 m, then a distance of 10 m-3 cm = 9 m 97 cm is compressed between the lens 12 and the LCD display 16 of 4 cm. You're stuck. Then, when the focus depths are set at equal intervals within this 4 cm, the distance, that is, the one, becomes logarithmic compression as shown in FIG. 4 (C). This means that in order to make a model with an accurate focus depth with a stereoscopic diorama board with parallax, the distance must be logarithmically compressed in the depth direction as shown in FIG. 4 (C). . Moreover, in order to form a model by compressing the distance logarithmically in the depth direction as described above and providing parallax to these models, a high level of skill and great labor are required. In this sense, as shown in FIG. 4 (A), the method of arranging the parallax-free stereo diorama board with a slight inclination to the inside is not accurate, but it is possible to easily add the focus depth and parallax, which is excellent. It can be said that it is a composition.

The present invention is not limited to the above embodiment, but various modifications can be made within the scope of the present invention.

For example, in this embodiment, L is used as the image display means.
Although the case where the CD display 16 is used has been described, the present invention is not limited to this, and for example, a thin cathode ray tube,
Alternatively, various image display devices such as a small television using a liquid crystal shutter and a plasma display can be used.

Further, in the present invention, the image displayed on the image display means does not necessarily have to be a three-dimensional image. For example, when the present invention is used for movie viewing as shown in FIG. 1B, the image displayed on the image display means may not be a three-dimensional image. Even in this case, according to the present invention, a scene such as a movie theater can be displayed in the non-effective display area 34 which is conventionally dark, as shown in FIG. it can. However, when the image displayed on the image display means is a three-dimensional image (pseudo three-dimensional image), the following unique effect occurs.

That is, normally, in order for the viewer to recognize that the image is a three-dimensional image, a standard for specifying the stereoscopic relationship is required, and only the image displayed on the image display means is stereoscopic. However, without this standard, I can't really feel the stereoscopic effect. However, in the conventional HMD device, as shown in FIG.
Only the three-dimensional image of the image display means was displayed, and there was no reference for this stereoscopic effect. On the contrary,
In the present invention, a diorama image by the diorama board 10 is displayed in addition to the three-dimensional video of the video display means. Therefore, the viewer can feel the stereoscopic effect of the three-dimensional video image displayed on the video image display means based on the diorama image, and the effect of the video image can be greatly enhanced.

Further, in this embodiment, the diorama board 10 is used.
The case where both the light guide transparent body 14 and the image light reflection plate 11 are provided as means for illuminating the above has been described. However, the present invention is not limited to this, and only one of the light guide transparent body and the image light reflecting plate may be provided, or in some cases, neither may be provided.

Further, the diorama board 10 according to the present invention.
As for the above, not only the diorama board representing the scene of the movie theater and the diorama board representing the cockpit of the spaceship shown in the embodiments, but also various diorama boards can be considered. 5A to 5D show examples of these variations. That is, FIG.
(A) Diorama board for horror movies and games, Fig. 5
5B is a diorama board for splatter movies / games, FIG. 5C is a diorama board for monster movies, FIG. 5D is a diorama board for live movies, and FIG. 5E is a diorama board for driving games.

In this embodiment, the case where the diorama image is formed only in the non-effective display area has been described.
