[0002]

2. Description of the Related Art In recent years, with the spread of AV equipment such as a television receiver for high-definition broadcasting (hereinafter, referred to as a high-definition television) and a projection display device, the diversification of images according to the image media is progressing. .

[0003] In the diversification of such images, a three-dimensional image display (hereinafter, referred to as a three-dimensional image device) capable of stereoscopically viewing an image has recently attracted attention.

[0004] In this stereoscopic image apparatus, a user generally looks at at least two images having different parallaxes with his right and left eyes.
The three images are viewed and perceived as a three-dimensional image in a pseudo space by viewing one image as a single image. For example, a three-dimensional image and a three-dimensional image of a photograph using a viewing mirror are used. As in a movie, left and right images are captured by each camera and projected on a polarizing screen by at least one or two projectors, and a viewer views the movie as a stereoscopic image using polarizing glasses. Various various stereoscopic image devices have been proposed.

[0005] Basically, as in the above stereo photography, images formed on the retinas of the left and right eyes are temporarily recorded as photographic images and sent to the left and right eyes to produce a three-dimensional effect. In the case of a movie, the stereo photography is applied, and the principle is the same.

Therefore, stereo photography, which is an important element of such a stereoscopic image apparatus, has been developed conventionally, and in particular, the principle of stereoscopic vision using stereo photography is 1838.
Wheatstone, a British physicist,
Tone) has published the stereo theory.

The stereo theory by Wheatstone is that the left and right eyes look at the object at different angles depending on the distance between the human right and left eyes, and this is fused by the visual center of the brain, and there is a solid It is a theory that gives a feeling.

[0008] That is, perspective can be obtained only by the two eyes at an interval of about 65 mm. That is, in order to perform stereoscopic vision, a stereo photograph in which left and right scenes having binocular parallax are projected, a so-called stereo. Pairs are a very important configuration requirement.

On the other hand, in such a stereo pair, two lenses are horizontally arranged at an optical axis distance required for stereoscopic viewing, that is, at an interval of 55 to 75 mm corresponding to an interval between lines of sight. In the Wheatstone three-dimensional image device, a left-right stereo pair or the like is used by handwriting.

In the present situation, in a stereoscopic image apparatus based on the line-of-sight distance, that is, the so-called eye width (55 to 75 mm), the film center of a stereo pair is formed with a dimension smaller than that. Therefore, the width of each of the right and left images is extremely small, that is, 60 mm or less, and a lens for enlarging the field of view is necessarily used. In this case, it is essential to match the optical axis of the eye, and a complicated structure is required to improve the accuracy in the optical system.

It is desirable that the stereo pair required for stereoscopic viewing be formed by precisely positioning the left and right images (hereinafter, referred to as a mount). However, as described above, the left and right images are small. Because of the size, it is very difficult to position the left and right images when forming a stereo pair, and it requires skill.

[0012] The two eyes of a human are lined up in a horizontal position (horizontal direction), and perceive a three-dimensional effect of an actual object or landscape by parallax in the horizontal direction. For this reason, landscape images are generally desirable for observing stereoscopic images,
There is a limit in the interpupillary distance, and it is almost impossible to increase the width of the image.In other words, a stereo pair composed of vertically long images appears, that is, the stereo pair using such a stereo pair is used. When stereoscopically viewed with an image device, not only stereoscopic vision but also realism is not satisfactory.

Therefore, a parallel mirror type stereoscopic image apparatus in which the interpupillary distance is pseudo-expanded in order to eliminate such inconvenience caused by the small size of the image has been conventionally used.

FIG. 26 shows such a parallel mirror type stereoscopic image apparatus.

FIG. 26 shows an example of a three-dimensional image apparatus of a parallel mirror system, and is a schematic configuration diagram showing a principle of an optical system and a schematic configuration. As shown in FIG. 26, the stereoscopic image apparatus 10 of the parallel mirror system is generally configured to extend the interpupillary distance by using at least a plurality of reflecting mirrors 12 and 13 as optical system reflecting means. Further, by expanding the interpupillary distance, for example, a stereo photograph 11 (stereo pair) in which left and right images arranged at predetermined positions are different from each other can be stereoscopically viewed in a pseudo space.

As shown in FIG. 1, the optical system reflecting means includes at least one pair of reflecting mirrors for pseudo-expanding the interpupillary distance and for allowing the left and right image light of the stereo pair 11 to enter both eyes. The first reflecting mirror 12 and the second reflecting mirror 1 are arranged so as to be symmetrical to each other and at a predetermined angle.
3 is provided.

The first reflecting mirror and the second reflecting mirror 13
Are arranged in a parallel positional relationship, and are arranged such that their reflection surfaces face each other.

The stereo pair 11 is arranged so as to be parallel to a line connecting both eyes, and is provided with a distance (distance from both eyes) necessary for stereoscopic viewing.

Each of the reflecting mirrors 12 and 13 serving as the reflecting means of the optical system arranged in this manner is supported by, for example, a support member (not shown) in an arrangement state (a state arranged at a predetermined angle). By supporting the reflecting mirrors 12 and 13 using the supporting members as described above, the left and right images (the left image 11a and the right image 11b) of the stereo pair 11 are viewed by the left and right eyes of the observer. That is, the left eye can see the left image 11a of the stereo pair 11 and the right eye can see the right image 11b.

That is, the eye width of the observer can be pseudo-expanded, and different images on the left and right, for example, the left image 11a and the right image 11b of the stereo pair 11 shown in FIG. Is viewed as a single image, and as a result, a fused image can be obtained, which enables so-called stereoscopic viewing.

On the other hand, a stereo pair 11 used in such a parallel mirror type stereoscopic image device 10 is a camera dedicated for stereo pair (hereinafter, abbreviated as a stereo pair camera), which normally outputs an arbitrary image for stereoscopic viewing. The image 11a viewed by the left eye and the image 11b viewed by the right eye are provided side by side as described above. The film center A has a predetermined size necessary for the operation. For this reason, the stereo pair 11
The image for one photographing target is projected by the stereo pair camera, but the left image 11a and the right image 11b are displayed.
Is slightly different because the images are taken from different directions (both eyes in parallel).

The stereo pair 11 usually uses a dedicated positioning member (not shown) to position the film center A required for stereoscopic viewing, for example. For example, a frame member having a predetermined size for performing the positioning, or a dedicated mount member for holding the left and right images 11a and 11b of the stereo pair 11 is used.

The stereo pair camera is generally provided with two left and right lenses at the same interval as the interpupillary distance, and using these lenses, the image light in a state where one image is viewed from each of the left and right lenses. And incident on the film.

When a film recorded by such a stereo pair camera is developed, various conditions such as the parallelism and height of the left and right images required for stereoscopic viewing or the film center are satisfied. Thus, the stereo pair 11 (see FIG. 26) can be formed precisely.
Is to be created.

Therefore, the stereo pair 11 used in such a parallel mirror type stereoscopic image apparatus 10 must be photographed by using the stereo pair camera as described above, and the photographed film is developed. In such a case, it is required that the right and left images be precisely formed so as to satisfy various conditions such as the parallelism and height of the left and right images or a film center required for stereoscopic viewing. For this reason, it is extremely difficult for the user to create the stereo pair, and this can be said to be one of the reasons why stereo photography, which has a long history, is not very popular.

Incidentally, the above-mentioned parallel mirror type stereoscopic image apparatus has a feature that an image size (stereo pair) of any size is possible in principle and that the size can be freely selected. For example, it has been widely used for business and research purposes.

However, when the image size of the stereo pair 11 used in such a parallel mirror type stereoscopic image apparatus is taken into consideration, for example, there is a strong demand for a user, and a necessary condition for stereoscopic viewing is provided. An image of a frequently used panoramic size (the size of a panoramic photograph and a width of 250 mm) is desirable, but the width of a commonly used A4 size larger than the width of the panorama size (standard standard size, In the case of A4 landscape, the width is 297 mm and the height is 210 mm, but in the case where the standard size is set based on the inner width 297 mm), the stereo pair 11 shown in FIG. Even if you don't have it, double the size of A4 size, about 600mm
And an extremely large stereo pair 11 is formed.

When such a stereo pair 11 is stereoscopically viewed using the stereoscopic image device 10 of the parallel mirror system, as shown in FIG. 26, the A4 size image is displayed on both eyes of the observer. In order to view as a fusion image, the left image 11a and the right image 11b of the stereo pair 11, respectively.
And the distance from the first reflecting mirror 12 to the first reflecting mirror 12 is increased, and the second reflecting mirror 13 also needs to finely adjust the parallel movement dimension with respect to the first reflecting mirror 12. is there.

In the case where the stereoscopic image apparatus 10 of the parallel mirror system is constructed based on the panorama size or the width of A4 as the image size for stereoscopic vision as described above, for example, the eye shown in FIG. Optical system means for increasing the width in a pseudo manner, ie, the first and second reflecting mirrors 1
The housing for accommodating the devices 2 and 13 and the means for supporting them must also be made large, and the stereo pair 11
However, there is a problem in that the size of the stereoscopic image device itself including the above must be large.

Therefore, in order for a user to perform stereoscopic viewing on an image having a width of, for example, a panorama size or an A4 size, a stereo pair that requires high precision and requires complicated positioning is used. In addition, since a stereoscopic image device having a large structure must be used, there is an inconvenience in use, and stereoscopic viewing cannot be easily performed, which is not satisfactory to the user.

[0031]

As described above, in a conventional stereoscopic image apparatus, it is not easy to accurately create a stereo pair used for stereoscopic viewing, and the image size of the stereo pair is, for example, a panorama size. A
In the case where the size is based on the width of the four sizes and stereoscopic viewing is performed using a parallel mirror type stereoscopic image device, the parallel mirror type stereoscopic image device itself is configured to be large, so that the However, there is a problem that the stereoscopic viewing cannot be easily performed.

Accordingly, the present invention has been made in view of the above-mentioned problems, and even when stereoscopic viewing of a stereo pair based on a panorama size or an A4 size width is performed using a stereoscopic image device, the present invention is not limited to this. It is an object of the present invention to provide a stereoscopic image apparatus which can be formed on a small scale without increasing the configuration scale, can easily create a stereo pair, and can perform a good stereoscopic view.

A positioning mark 4b as a reference mark for facilitating the positioning of the stereo pair 3 when the stereo pair 3 is inserted is provided vertically.

In this embodiment, the pair of second reflecting mirrors 6 are attached to a fixing member 6a for fixing the second reflecting mirror, for example, to adjust the interpupillary distance of the observer.
The reflecting mirror 6 may be provided with an interpupillary distance adjusting means capable of adjusting the interpupillary distance desired by the observer by rotating or translating the reflecting mirror 6 in this case.
The first reflecting mirror 5 may be configured to cooperate with each other so that stereoscopic vision can be favorably performed according to the position of the reflecting mirror 5.

Next, the principle of the stereoscopic image apparatus having such a configuration will be described in detail with reference to FIG. As shown in FIG. 2, the stereoscopic image device 1 in the present embodiment is an example of a fixed stereoscopic image device in which the first reflecting mirror 5 and the second reflecting mirror 6 are fixed, for example. LR
The image size for use is, for example, based on the width of A4 that can accommodate a panorama size, and the focal length L to a stereoscopically fused image corresponding to this image size is 5
This is the case where it is assumed to be 00 mm.

In this case, an L-size image 3 having parallax, which forms a stereo pair 3 having an A4 size and a width dimension M.
As described above, the image light of each of the a and R images 3b is tilted inward with respect to the parallel line parallel to the center line of the stereo pair 3 with the reflection surface at the tip of 24.220 ° as a fulcrum. The light is reflected by the pair of first reflecting mirrors 5 at the same relative angle as the incident angle, and is incident on the second reflecting mirror 6.

Next, the L / R image light reflected by the first reflecting mirror 5 is tilted outward with the reflection surface at the tip end as a fulcrum at 20.780 ° with respect to a parallel line parallel to the center line. The light is reflected by the second reflecting mirror 6 at the same reflection angle as the incident angle, and is incident on both eyes of the observer. Here, the eye width of the observer is generally 55 mm to 7 mm.
Although it is 5 mm, for example, in this embodiment, it is assumed that 60 mm
mm.

As described above, the L / R image light of the stereo pair 3 incident on both eyes changes the parallax when the observer appropriately turns the visual field of both eyes inward. The image light for L and R is viewed as a single image, and a fused image is obtained in a pseudo space. As a result, the image can be stereoscopically viewed.

For good stereoscopic vision, it is desirable that the focal length L from both eyes to the fusion and the optical axis distance from both eyes to the stereo pair 3 also match. The present embodiment also satisfies such a condition. For example, as shown in FIG. 2, in the left eye portion, the optical axis distance R from the left eye to the second reflecting mirror 6
1, the optical axis distance R2 from the second reflecting mirror 6 to the first reflecting mirror 5, and the optical axis distance R3 from the second reflecting mirror 6 to the L image 3a of the stereo pair 3 The distance is the same size as the distance M to the fusion, that is, 500 mm.

Specifically, R1 is 25 mm,
The R2 is 261.3 mm and the R3 is 213.65 m
m, and the total optical axis distance is 499.95 mm. In this case, there is a slight difference in length, but it is possible to obtain a good stereoscopic effect without affecting stereoscopic viewing.

Although not shown, the distance from the parallel line connecting both eyes to the center of the stereo pair 3 is preferably 196.90 mm in the above case. In addition, by positioning the center position of the stereo pair 3, it is possible to perform good stereoscopic vision. In this embodiment,
For example, the positioning marks 4b of the guide frame member 4 may be provided so as to correspond to the dimensions of 196 and 90 mm.

Therefore, by adopting such a configuration, for example, the image size of the stereo pair 3 can be set to a panoramic size, and the size within the width of the A4 size can be set. The stereo pair 3 having an appropriate image size can be favorably stereoscopically viewed.

Next, with respect to the principle of the optical system in the three-dimensional image device shown in FIG. 1 based on a parallel mirror type three-dimensional image device as a conventional technique, the concept of the optical system was improved. This will be described in detail with reference to FIGS. Note that, for simplification of the description, the main part in the left part of the stereoscopic image device will be described.

First, in the parallel mirror type stereoscopic image apparatus as a conventional technique shown in FIG. 26, for example, as shown in FIG. The optical axis distance from to the left image 11a of the stereo pair 11 is, for example, 500 mm as in the present embodiment.

In this case, the first reflecting mirror 12 and the second reflecting mirror 13 are arranged in a parallel positional relationship and the reflecting surfaces are opposed to each other. The distance in the following (abbreviated as X direction) is, for example, 150 m.
m, and the angles of the respective reflecting mirrors 12 and 13 are each inclined by 45 °, and the distance from the left image 11a to the first reflecting mirror 12 is set to 300 mm. The image light of the image 11b can be reflected by the first reflecting mirror 12, then reflected by the second reflecting mirror 13, and then be incident on the point P of the left eye. Of the total optical axis distance of 500 mm to the left image 11a.

Next, in consideration of the scale of reduction in the X direction, which is a problem of the conventional parallel mirror system, the distance between the first reflecting mirror 12 and the second reflecting mirror 13 shown in FIG. 3 in the X direction. Try to reduce the dimensions. In this case, for example, as shown in FIG. 4, the distance from the point P of the left eye to the left image 11a of the stereo pair 11 is maintained at 500 mm, and the X between the first reflecting mirror 12 and the second reflecting mirror 13 is maintained. In a case where the directional distance is reduced as much as possible, the first reflecting mirror 12 shown in FIG. 3 is rotated clockwise while maintaining a distance dimension of 150 mm from the center point of the second reflecting mirror 13 as a viewpoint. And then left image 1a
In order for the image light of the above to enter the point P via the first reflecting mirror 12 and the second reflecting mirror 13 satisfactorily, the first and second reflecting mirrors 12 and 13 are respectively set to 22.5 ° (45 °). 1/2 of ゜
Angle) is arranged at an angle inclined outward.

For this reason, as shown in FIG. 4, if the left image 11a of the stereo pair 11 is constructed without changing the distance dimension from the second reflecting mirror 300 to 300 mm, the left image 11a extends from the point P in the vertical direction (hereinafter referred to as the Y direction). The image light of the left image 11a passes through the first reflecting mirror 12 and the second reflecting mirror 13 and is disposed far away from the left eye 11a. The light can be reliably incident on the point P, and the distance dimension in the X direction between the first reflecting mirror 12 and the second reflecting mirror 13 can be reduced to 106 mm.

However, in the method shown in FIG. 4 as described above, the scale can be reduced in the X direction, but the left image 11a of the stereo pair 11 is extremely
Since it is arranged far from the point, the scale in the Y direction increases, and the purpose of reducing the scale of the apparatus cannot be satisfied. Note that, specifically, the distance dimension in the Y direction of the left image 11a of the stereo pair 11 is 456 mm.

In order to solve the above problem, for example, as shown in FIG.
1a is arranged at a position rotated inward by 45 ° while maintaining a distance dimension of 300 mm from the first reflecting mirror 12, and the first reflecting mirror 12 also obtains an angle of 22,5 ° inside. The center point is used as a fulcrum, that is, it is configured to be rotated by 45 °.

As a result, as shown in FIG. 5, the image light of the left image 11a of the stereo pair 11 is surely incident on the point P of the left eye via the first reflecting mirror 12 and the second reflecting mirror 13. In addition, the scale can be structurally reduced in the X direction and the Y direction.

On the other hand, the stereoscopic image apparatus shown in FIG. 5 relates to an optical system using one eye. Here, for example, the arrangement of these optical system reflecting means and the binocular image which is indispensable for enabling a stereoscopic view. Considering the optical system concept of FIG.
In the arrangement configuration of the optical system reflection means shown in the above, this is good when the optical axes of both eyes are parallel and there is an image at infinity, but in this case, the distance to the image is finite 500 mm, so
For example, when the observer observes with the naked eye, fusion cannot be obtained in a natural state, and as a result, correct stereoscopic vision cannot be performed.

Therefore, in order for the observer to obtain a fusion image with two eyes and to enable a stereoscopic view in a natural state without difficulty, naturally, the visual fields of both eyes must be set at an appropriate angle (hereinafter, convergence). It is necessary to set a state of fusion convergence in which the lines of sight of the two eyes coincide with each other toward the inside at the angle). Here, the concept of both eyes for performing such a stereoscopic view is shown in FIG.

As shown in FIG. 6, for example, the interpupillary distance of both eyes of the observer is supposed to be 60 mm, the distance dimension from both eyes to the fusion is 500 mm, and the focus is coincident in such a state. In this case, the convergence angle of each eye at this time is 3.4.
40 °.

Further, even when the fusion image is, for example, a normal image, it is considered that the angle when the focus is coincident with both eyes is the same.

Therefore, when the distance from both eyes to, for example, a fusion which is a feature of stereoscopic vision is 500 mm, a necessary condition for enabling stereoscopic vision is as follows.
This requires a specific angle of 440 °.

Then, based on such a concept for stereoscopic viewing, for example, when the configuration of the optical system shown in FIG. 5 is considered, first, as shown in FIG. The angle of the optical axis to the second reflecting mirror 13 is inclined by 3,440 ° with respect to the center line in the Y direction, and the optics of the second reflecting mirror 13 and the first reflecting mirror 12 are linked to this. The system reflection means is also disposed at a position rotated inward by 3.440 °.

Therefore, in the configuration of the optical system shown in FIG. 5, as described above, if stereoscopic vision is performed with both eyes in this case, it is not possible to obtain a fusion image in a reasonable natural state. There is a problem that the optical axes of the eyes do not coincide with each other and become infinite. However, as shown in FIG. 7, it is necessary to perform a stereoscopic view in a natural state without difficulty by both eyes. By configuring the first and second reflecting mirrors 12 and 13 based on the concept (see FIG. 6),
Even when the image is observed with both eyes, the optical system concept for both eyes that enables stereoscopic viewing is satisfied.

However, if the configuration is based on the above-described concept of the optical system that enables stereoscopic vision, for example, the point P based on the position of the left eye of the observer expands in the X direction. There is a disadvantage that the eye width becomes large, that is, it is necessary to adjust the eye width to a distance dimension that temporarily assumes an average eye width of 60 mm.

For this reason, as shown in FIG. 8, for example, the eye width of the observer is assumed to be 60 mm and the point P of the left eye is fixed. When it is considered to satisfy the configuration, from the relationship of the convergence angle of one eye of 3.440 ° necessary to view the fusion,
For example, the first reflecting mirror 12 may be rotated inward of 3.440 ° × ° = 1.720 ° from the angle of 22.5 ° shown in FIG. 5, that is, 24.220 °. Similarly, the second reflecting mirror 13 has an angle 2 shown in FIG.
What is necessary is just to rotate inward from 1.75 degrees from 2.5 degrees, ie, it becomes 20.780 degrees. In this case, in order to effectively make the left image 11a of the stereo pair 11 incident on the point P of the left eye, the first reflecting mirror 12 and the second reflecting mirror 1 are used.
3 is 154 mm, and the first
The optical axis distance dimension from the reflecting mirror 12 to the left image 11a of the stereo pair 11 is 296 mm.

Accordingly, by adopting such a configuration, it is possible to more effectively satisfy the optical concept of enabling stereoscopic viewing by both eyes, for example, the second and first points are connected from the point P connecting both eyes. When the optical axis distance to the left image 11a of the stereo pair 11 is 500 mm via the reflecting mirrors 13 and 12, the optical axis distance dimension must match the distance dimension (500 mm) from the point P to the fusion. In other words, stereoscopic viewing of the stereo pair 11 in a natural state is possible.

Further, here, the size of the image of the stereo pair 11 in this embodiment, that is, the A4 size (width 29) enabling the panorama size (width 250 mm).
In order to satisfy the condition of the image size of 7 mm), the image light of such a size can be accommodated within the visual field of both eyes, and the image is not vignetted by the second reflecting mirror 13. The first reflecting mirror 12
In addition, a positional relationship based on the size of the second reflecting mirror 13 and the arrangement distance is searched, and in this case, the total optical axis distance from the point P to the image is set to about 500 mm.

As a result, for example, as shown in FIG. 9, a schematic configuration of the optical system of the stereoscopic image apparatus which is a feature of this embodiment can be obtained.
When the image size is based on the A4 size (297 mm in width), the first reflecting mirror 12 is enlarged to a predetermined size,
Further, the second reflecting mirror 13 is also configured to have a predetermined size so that there is no vignetting of the image.

Therefore, if the distance dimension from the parallel line connecting both eyes of the observer to the fusion in stereoscopic view is 500 mm, for example, the optical axis distance dimension R1 from the point P to the second reflecting mirror 12 is 20 mm The optical axis distance dimension R2 from the second reflecting mirror 13 to the first reflecting mirror 12 is 264 mm,
The left image 1 of the stereo pair 11 from the second reflecting mirror 13
The optical axis distance dimension R3 up to 1a is 216 mm, and the total optical axis distance dimension TL is R1 + R2 + R3 = 500 mm
Becomes Thus, the distance dimension 500 mm from the parallel line connecting the eyes of the observer to the fusion in stereoscopic view matches the optical axis distance dimension TL, and the image size of the stereo pair 11 is A4 size ( 297m wide
In the case of m), stereoscopic vision can be achieved.

Further, the second reflecting mirror 1 from the point P shown in FIG.
When the optical axis distance R1 up to 3 is set to, for example, 25 mm and stereoscopic viewing is performed in accordance with the image size of the panorama size (250 mm), the R2 is 261.3 mm,
R3 is 213.65 mm, and the total optical axis distance dimension TL
Is 499.95 mm. Therefore, even in this case, since the distance dimension substantially matches the distance to the fusional image of 500 mm, it is possible to perform a natural and natural stereoscopic view in the same manner as described above.
The distance from the point to the center of the image is 196.90m
m.

In other words, the configuration in which the optical system reflecting means and the stereo pair are arranged at the optical axis distance dimension as described above is, for example, the arrangement configuration of the optical system in the stereoscopic image apparatus 1 shown in FIG. FIG. 1 in this embodiment
FIG. 10 shows a specific configuration of an optical system of the three-dimensional image device.

As shown in FIG. 10, as described with reference to FIGS. 3 to 9, in the three-dimensional image device 1 of this embodiment,
Even if the image size of the stereo pair 3 is A4 size (297 mm), stereoscopic viewing is possible. In the example shown in the figure, the image size of the stereo pair 3 is set as the reference image size of the panorama size, and stereo viewing is possible. In this case, the optical system reflection means and the like are configured as described above.

Therefore, the stereoscopic image apparatus 1 shown in FIG.
For example, when the image size of the left and right image portions 3a and 3b of the stereo pair 3 is configured as a panorama size that is frequently used in general, the first reflecting mirror 5 formed in a predetermined size is Second reflecting mirror 1 tilted 24.200 ° inward with respect to pair 3 and formed with a predetermined size
3 is configured to be inclined outward by 20.780 °, and in this case, the eye width of the observer is configured to be 60 mm. In this case, the distance dimension from the parallel line connecting the interpupillary distance to the center position of the stereo pair 3 is 19 in this case.
6.90 mm.

Next, the observation method and operation of the stereoscopic image apparatus shown in FIG. 1 will be described in detail with reference to FIGS. First, for example, the image display means 3 shown in FIG.
Is configured as a (panoramic size) stereo pair 3 in a panoramic photograph, two commercially available panoramic cameras are mounted side by side and in parallel, and then a pair of left and right prints printed simultaneously are printed. It is configured such that it is stuck on the front and back and sandwiched using the frame member 3c. Further, at this stage, the frame member 3c is notched so that, for example, as shown in FIG. 12 (a), one sheet of the backing member is bent, and each of the front and back surfaces has a panoramic image size. By using it as a panorama-size mount member formed in this way, the left and right prints can be easily positioned and the stereo pair 3 can be used.
Can be created. In addition, normal size (standard size in the photo, normal service size 82mm × 11
In the case of creating a stereo pair 3 of 6 mm), as shown in FIG. 12 (b), each of the front and back surfaces of the mount member is cut out to have a normal size as shown above. The stereo pair 3 of the normal size can be easily created by using the stereo pair.

A center mark 3d indicating the center point of the image size is previously formed on the frame member 3c.
It should be provided at the bottom.

Next, the stereo pair 3 created in this way is
Together with the frame member 3c, is inserted along the groove 4a of the guide frame member 4 from the rear of the stereoscopic image device 1 shown in FIG. 1 and slides while being guided by the guide frame member, and the stereo pair 3 is pinched. The center mark 3d of the frame member 3c is adjusted to correspond to the positioning mark 4b provided on the guide frame member 4. Thereby, the image center position of the stereo pair 3 and the second position in the stereoscopic image device 1
The optical axis distance dimension of the optical system with respect to the reflecting mirror 6 is satisfied, and the setting of the stereo pair 3 to the stereoscopic image device is completed.

In the illustrated example shown in FIG. 1, the positioning mark 4b of the guide frame member 4 is positioned at a distance of 196.degree. From a parallel line connecting both eyes so as to correspond to a panoramic image size.
Although it is provided at a position where it becomes 90 mm,
Other than this, for example, a normal size image size, or A4
The positioning marks 4b may be provided at predetermined distances corresponding to the image size such as the size (297 mm in width). Also, for example, a fixing member 6a for fixing the second reflecting mirror 6 so as to correspond to the positioning mark 4b.
A stopper member 6b (see FIG. 1) which is joined and locked and positioned when the slide of the stereo pair 3 arrives at the upper rear portion may be provided. It may be provided at a predetermined position on the transparent member 2a or the bottom surface 2b on the upper surface of the image device 1.

Then, the observer approaches both eyes from a height corresponding to the pair of second reflecting mirrors 6 shown in FIG.
The left and right images 3a and 3b of the stereo pair 3 are stereoscopically viewed by the left and right eyes, respectively. In this case, for example, FIG.
As shown in FIG. 0, in one eye of the left eye, the image light of the left image 3a of the stereo pair 3 is reflected via the first reflecting mirror 5 and the second reflecting mirror 13, and the left side of the observer is left. It will be well incident on the eye. Although not shown, the image light of the right image 3b of the stereo pair 3 similarly enters the right eye well to the right eye.

As a result, the eye width of the observer is reduced by the second reflecting mirror 6.
The two image lights which are pseudo-expanded by each other, and which are incident respectively, form a single image in the pseudo space by turning the field of view in an appropriate inward direction by the observer, and view this image as a fusion image. That is, stereoscopic viewing of an image projected on the stereo pair 3 having a panoramic size can be performed in a natural and reasonable state.

For correction of the stereoscopic image apparatus having such a configuration, first, an observer observes the second reflecting mirror 13 at a predetermined position, and at this stage, for example, the stereo pair 3 is moved forward. Or, when the observer slides backward while observing, it is possible to find the optimal position of the stereo pair that can be stereoscopically viewed in a reasonable natural state, and to compensate for individual differences in interpupillary distance. It can be performed.

Therefore, in the stereoscopic image apparatus 1 capable of stereoscopically viewing the stereo pair 3 having the panoramic image size as described above, for example, as shown in FIG. When the configuration of the optical system showing the three-dimensional image device of the present embodiment, the right side of the configuration of the optical system of the three-dimensional image device of the present embodiment, and the distance to the image is tentatively 500 mm When comparing the configuration scale of these three-dimensional image device The stereoscopic image apparatus according to the present embodiment has an X
The configuration scale can be reduced in the direction (horizontal direction) and the Y direction (vertical direction).

Further, it is very difficult to create a stereo pair used for the left stereoscopic image apparatus, and it is required to have high accuracy in positioning when attaching to the apparatus. ) Can be easily created, and the stereo pair 3 can be easily positioned with respect to the device.

Therefore, according to the present embodiment, not only can a user easily create a stereo pair having a desired image size, but also a stereoscopic image apparatus is configured according to this stereo pair. The configuration scale of the device can be reduced.

Further, by using such a stereoscopic image apparatus, it is possible to easily perform stereoscopic viewing of the image of this stereo pair, and furthermore, since the optical system of the apparatus is constructed without using a lens, light It is not necessary to align the axes with high precision, and at the same time, there is no fatigue caused by aligning the eye with the optical axis of the device side, no fatigue caused by mismatch between the eye and the lens, and furthermore, low cost. It is clear that can be done.

In this embodiment, the fixed type stereoscopic image apparatus constituted by fixing the first and second reflecting mirrors at a predetermined angle has been described. The angle of the first and second reflecting mirrors may be configured to be optimally adjusted (corrected) based on an optical system that enables stereoscopic viewing, and the reflecting means of the second optical system may be configured as an observer. For example, an interpupillary distance adjusting means that can rotate or translate the second reflecting mirror may be provided so as to be able to change according to the interpupillary distance. Further, the interpupillary distance adjusting means in this case may be configured to be driven electrically, mechanically, or automatically, for example, or may be configured to be driven manually.

Further, in the present embodiment, the description has been given of the A4 size width (297 mm) in which the image size of the stereo pair satisfies the panorama size image.
m), the stereo pair may be configured such that
In this case, the same effect as in the present embodiment can be obtained by enlarging the vertical dimension in the first and second reflecting mirrors as well.

Further, by using this principle, a larger size is also possible. Only the interpupillary distance is maintained as it is, and the positional relationship between the mirror and the image is enlarged in a similar manner. Obtainable.

In this embodiment, the mirrors used for the first and second reflecting mirrors can be composed of, for example, mirrors generally used as reflecting means of an optical system. That is, any reflector may be used as long as the reflector is made of a material that does not distort the reflection surface. In this case, the effect can be obtained.

In the present embodiment, a transparent member is used on the upper surface of the apparatus in order to secure the brightness when stereoscopically viewed. For example, the brightness when stereoscopically viewed is more effectively reduced. To ensure, for example, the upper part of the stereoscopic image device,
Alternatively, a lighting device such as a spotlight may be provided on the side surface or the rear portion to illuminate the left and right image portions of the stereo pair to obtain an optimal brightness.

Furthermore, the present embodiment is characterized in that stereoscopic viewing is performed without using a lens. For example, in order to perform optimal stereoscopic viewing, a lens such as a loupe is used to correct the optical axis. In this case, the second
For example, a pair of eyepieces as lenses are detachably provided in front of the reflecting mirror so as to be parallel to both eyes of the observer, so that the observer can observe even in the state of the naked eye or when using glasses. You may do it. In addition, when the loupe is used, it is possible to magnify and observe an image, so that a wider field of view is obtained and the sense of presence is increased.

FIG. 13 shows a second embodiment of the stereoscopic image apparatus according to the present invention.
A display device is provided for displaying images using two video signals so as to enable stereoscopic viewing as a moving image instead of a still image, and a stereo pair is provided to display images with parallax on these screens. FIG. 13A shows a configuration of a frame member used for a stereo pair in this case, and FIG. 13A shows a screen size corresponding to a display device having an aspect ratio of 9:16 enabling reception of high-definition broadcasting. Shows a schematic configuration of the frame member configured in,
FIG. 13B shows a schematic configuration of a frame member configured to correspond to a display device having a screen size of up to 12 inches.

In this embodiment, a stereo pair as an image display means shown in FIG. 1 is improved, and although not shown, for example, a liquid crystal color television receiver (hereinafter, referred to as a display device having as small a thickness as possible). Liquid crystal TV) and two display screens facing each other.
It is a stereo pair that is detachably joined back-to-back and integrally configured to enable stereoscopic viewing of a so-called moving image.

That is, the left and right liquid crystal TVs receive, for example, video signals having parallax, respectively, and display images on respective monitors of the liquid crystal TVs, and FIG. 1 is configured according to these liquid crystal TVs. It is characterized in that an image displayed on each screen of the liquid crystal TV as a stereo pair can be stereoscopically viewed using a stereoscopic image device. As the display device, for example, a television receiver using a liquid crystal or an ultra-thin CRT, a high-definition television receiver, or the like may be used. Alternatively, a computer using a liquid crystal or an ultra-thin CRT may be used. Video displays for terminals, personal computers, CAD, and video games may be used.

Therefore, as shown in FIG. 13 (a), when the liquid crystal TV as a stereo pair is provided as a TV capable of, for example, high-definition broadcasting, these TVs are provided.
A frame member 7 for a high-definition liquid crystal TV, which is obtained by improving the frame member (see FIG. 12) used in the above embodiment so as to correspond to a screen having an aspect ratio of 9:16, is connected to, for example, a liquid crystal bonded on the front and back. Attach so as to be sandwiched between TVs, and then stereoscopic image device so as to support liquid crystal TVs (see Fig. 1)
Can be set in a stereoscopic image device (not shown) configured as described above to stereoscopically view the front and back images as a stereo pair of the liquid crystal TV, that is, a moving image or a still image based on a video signal having parallax.

When the display screen size of a liquid crystal TV set as a stereo pair is enlarged, for example, it can be configured to have a screen size of at least 12 inches.
In this case, as shown in FIG. 13B, the setting of the stereoscopic image device is performed in the same manner as above using the liquid crystal TV frame member 8 configured for 12 inches, and then the video signal having parallax is transmitted to the 12 inch. By supplying the liquid crystal TV of each inch, a 12-inch moving image or a still image can be stereoscopically viewed.

Further, each of the liquid crystal frame members 7 and 8 shown in FIGS. 13A and 13B has a thickness O in which, for example, two liquid crystal TVs are overlapped. It is easy to accommodate the liquid crystal TV, and when a positioning mark (not shown) is provided at the center of the frame member for the liquid crystal TV, the positioning to the stereoscopic image apparatus is performed in the same manner as in the above embodiment. It can be made easier.

Therefore, according to the present embodiment, for example, the display screens of two liquid crystal TVs of the same size are joined to the image display means as a stereo pair shown in FIG. When a stereo pair is formed by using a dedicated frame member, a video signal having parallax is supplied to each of these liquid crystal TVs to display the screen, and the liquid crystal TVs are displayed on a screen according to the stereo pair composed of the two liquid crystal TVs. The image displayed on the liquid crystal TV screen, that is, when this image is a moving image, can be easily stereoscopically viewed as a moving image by observing using the stereoscopic image device configured as described above. In this case, stereoscopic vision can be easily performed.

Incidentally, in the configuration of the stereoscopic image device in the case where the liquid crystal TV is configured as a stereo pair, it is sufficient to improve the hardware so that the stereo pair can be set satisfactorily. You may comprise so that it may be the structure which can be set.

In the present embodiment, for example, a dedicated stereo video camera or two video cameras capable of capturing an image with parallax is used for two liquid crystal TVs as a stereo pair. Each of the liquid crystal TVs may be configured to supply a video signal. In this case, a captured image desired by the user can be stereoscopically viewed as a moving image or a still image. Even when a stereo broadcast program (a broadcast program by a stereo camera) is started, stereoscopic viewing can be easily performed.

Further, in the present embodiment, computer graphics, computer CAD,
It can also be used for computer games and the like.

Next, an example of the stereoscopic image apparatus shown in FIG. 1 in a case where the stereoscopic image apparatus shown in FIG. 1 is configured to be foldable so that it can be easily carried, for example, for carrying around, is shown in FIG.

A rotation support member 14 is provided, which is sandwiched by these fixing members 12 and is rotatably mounted in a predetermined dimension range in the horizontal direction with the point F as a fulcrum. The rotating member 14 drives an interpupillary distance adjusting means 17 provided on a second reflecting mirror 16 to be described later, so as to rotate around the point F in accordance with the adjustment level of the interpupillary distance adjusting means 17. As a result, together with the second reflecting mirror 16 and the first reflecting mirror 15, all of the optical system reflecting means can rotate around the point F of the rotating support member 12 as a fulcrum. Accordingly, it is possible to correct the optical system when adjusting the interpupillary distance of the observer.

The setting to 1 is performed.

On the other hand, as a schematic structure of the folding type, various structures such as a link mechanism or an opening and closing method of opening and closing each other around at least two points can be considered. For example, as shown in FIG. 14, three types of rotating members 14a composed of at least a pair of upper and lower members rotatably attached to predetermined positions of the rotating support member 14, as shown in FIG. For example, by using a link mechanism including 14c and 14d and a second rotating member 14b having a hinge structure near the center of one of the rotating members 14a, for example, the first reflecting mirror 15 can be used. Can be folded.

As shown in the figure, the folding structure by the link mechanism is, for example, a fixing member 14e provided in front of the rotating support member 14 for fixing the rotating support member 14 at a predetermined width. A first rotating member 14a which is provided with a predetermined width, is rotatably provided around a point Q, and has a base end formed in a click shape; The base is attached to the vicinity of the center so as to be rotatable around a point R, and has a base end on both upper and lower ends of a reflector support member 15a having the first reflector 15 adhered to the inside thereof with a point V as an axis. A second rotating member 14b provided to be stopped, one of which is axially fixed around the V point of the reflecting mirror supporting member 15a, and the base end of which is the rotating supporting member 1
A third pivoting member 14c, which is pivotally fixed at a predetermined position in the rear part of the mirror 4 at a point T as a fulcrum, and a point X at the upper and lower ends on the other side of the reflector support member 15a. One end is fixed to the shaft, and the base end is the rotation support member 14.
And a fourth rotating member 14d which is rotatably fixed at an end on the rear side of the shaft with the point U as a fulcrum.
Further, such rotating members 14a, 14b, 14c, 1
4d are all configured as a pair, and are attached so that each can hold a predetermined width.

The first rotating member 14a is provided with a locking means whose base end is formed in a click shape. For example, when the first rotating member 14a is opened and closed using a link mechanism in the three-dimensional image device 11, the reflecting mirror is provided. The locking means of the first rotating member 14a is locked on the axis about the V point of the fixed member 15a, and thus the positioning of all the rotating members constituting the link mechanism is completed. You can do it.
That is, the arrangement condition of the first reflecting mirror 15 as an optical system reflecting means that enables stereoscopic viewing can be satisfied, similar to the fixed type stereoscopic image apparatus in the first embodiment.

Here, specific dimensions for forming the link mechanism in this embodiment are, for example, as shown in FIG. 15, the length of the first rotating member 14a (from the axis Q to the axis V). ) To the length 12 of the second rotating member 14b.
The length is set to be twice as long as 7.51 mm, and a shaft R serving as a hinge mechanism is provided at a point of 127.51 mm of the first rotating member 14a. In this case, the length of the third rotating member (the length from the axis T to the axis T) is 256.52 mm, and
Of the rotating member 14d (the length from the axis U to the axis X) is 160 mm. Next, the length of the reflector fixing member 15a is set to, for example, 160 mm.

According to the link mechanism having such a configuration, the optical system reflecting means (first reflecting mirror 15) can be fixed in the same arrangement as that of the fixed type stereoscopic image apparatus in the first embodiment. When folded, it can be effectively stored.

The material of the rotating member used in the link mechanism may be made of a material such as a light metal such as aluminum, or a synthetic resin such as plastic. Even in such a case, any material may be used as long as the material has mechanical strength so as not to deform. Further, without forming the locking means provided on the first rotating member 14a, for example, the reflecting mirror fixing member 15a of the second rotating member 14b can be used.
A locking means for locking the first rotating member 14a is provided on the side surface on the side, and the first rotating member 14a is
The rotation means 14b may be configured to be locked by this locking means when it reaches the rotation member 14b.

A second reflecting mirror 16 is provided to reflect each image light reflected from the first reflecting mirror 15 to be emitted to both eyes of an observer.

The first reflecting mirror 15 is, as described above, the reflecting mirror supporting member 1 attached to the link mechanism.
It is stuck on the inner side surface of 5a with the reflection surface inside, and is stored by the link mechanism when folded.

The second reflecting mirror 16 is attached to a reflecting mirror fixing member 16a for fixing each reflecting mirror, and is disposed with the reflecting surface facing outward. Reference numerals 16a are respectively attached to both side surfaces of the interpupillary distance adjusting means 17 fixed to the main body. As shown in FIG. 16, for example, each of the reflecting mirror fixing members 16a is provided on the rotation support member 12 and the upper and lower front surfaces thereof are pivoted by pins Z. The second reflecting mirror 16 itself can be rotated and housed.

Although not shown, the reflecting mirror fixing member is provided so that the second reflecting mirror 16 can be automatically opened and locked at a predetermined angle when the stereoscopic image apparatus 11 is opened and closed. 16a, for example, this reflector fixing member 16
There is provided a spring member that constantly urges a in an outward direction, and a locking member 16b for locking at a predetermined angle when opening and closing. As a result, even when the stereoscopic image device 11 is used by opening and closing, the second reflecting mirror 16 is automatically opened and positioned at a predetermined angle without positioning the angle of the second reflecting mirror 16, so that the stereoscopic image is immediately displayed. Is what you can do.

On the other hand, the foldable three-dimensional image device 11 having the above-described structure is configured such that when folded (at the time of storage) as shown in FIG. 16, at least two cover members, a first cover member 18 and a second cover member 18 are provided. Of the optical system reflecting means folded by the link mechanism by the cover member 19 of FIG.
Reflector fixing member 1 together with the second reflecting mirrors 15 and 16
5a and the like can be covered (encased).

The first cover member 18 is, for example, as shown in FIG.
4 is formed with a predetermined width so as to cover the pair of rotation supporting members 14, and the end portion is formed of the rotation supporting member 1.
4Attached on a shaft S provided at the rear portion as a fulcrum, and attached rotatably.

The second cover member 19 is formed to be at least wider and longer than the first cover member 18, and has an end portion about a shaft Y provided in front of the rotation support member 14 as a fulcrum. It is worn in a cram school and attached rotatably.

Therefore, in the open / closed state (during use), the first and second cover members 18 and 19 are arranged on the side surface of the three-dimensional image device 11 by rotating, respectively. In addition, it is possible to prevent unnecessary light from entering from outside, that is, by providing a shielding effect, it is possible to concentrate stereoscopic vision by an observer.

The folding operation by the link mechanism of the foldable three-dimensional image apparatus having such a configuration will be described in detail with reference to FIGS. First, as shown in FIG. 14, the axis R serving as a hinge mechanism between the first rotating member 14a and the second rotating member 14b is moved in the direction of arrow A (arrow in FIG. 14). 1 rotating member 14
a is rotated about the axis Q toward the inside of the apparatus.

For this reason, the locking means (FIG. 1) of the first rotating member 14a locked to the axis V of the reflector fixing member 15a.
5), and the second rotating member 14b is supported by the axis R forming the hinge mechanism as a fulcrum in the direction of arrow B (FIG. 1).
4, the reflecting mirror fixing member 15a moves toward the inside of the apparatus.

Next, the axis V of the reflecting mirror fixing member 15a is
A third rotating member 14c rotatably attached to the
The fourth turning member 14d rotatably attached to the axis X of the opposite reflecting mirror fixing member 15a is interlocked with the reflecting mirror fixing member 15a moving toward the inside of the apparatus, and is connected to the third turning member 14d. The turning member 14c is turned in the direction of arrow C (the direction of the arrow in FIG. 14), and the fourth turning member 14d is turned in the direction of the arrow D (the direction of the arrow in FIG. 14).

Thereafter, when the first turning member 14a reaches the inside of the turning support member 14, the reflecting mirror fixing member 15a is completely housed in the turning support member 14 and at the same time, another mirror is fixed. The pivoting members 14b, 14c, 14d are also housed in the pivoting support member 14, and as a result are completely folded as shown in FIG.
The folding operation is completed by rotating the cover member 18 in that order and then rotating the second cover member 19.

By the way, the folding type stereoscopic image apparatus in this embodiment is provided with the interpupillary distance adjusting means for adjusting the interpupillary distance according to the observer as described above. Will be described with reference to FIG. 17 and FIG. FIG. 17 shows the second reflecting mirror 16 shown in FIG.
The main part of the interpupillary distance adjusting means is enlarged, and as shown in this figure, the second reflecting mirrors 16 are respectively adhered to the reflecting mirror fixing members 16a, and the reflecting mirror fixing members 16a Interpupillary support member 17a as adjusting means 17
18 (see FIG. 18).

For this reason, as shown in FIG. 18, since the interpupillary support member 17a is attached to the rotation support member 14, for example, the pair of interpupillary support members 17a are moved outward at the same level as each other. In addition, when moving in the horizontal direction, the rotation support member 14 can rotate around the point F shown in FIG. 14 as an axis.

In order to make it possible to change the interpupillary distance in accordance with the interpupillary distance of the observer, for example, the pair of second reflecting mirrors 16 are respectively moved in parallel so as to be in accordance with the interpupillary distance of the observer. Method to obtain the interpupillary distance, or the second
There is a method of adjusting the interpupillary distance by rotating the reflecting mirror 16 described above, but in the present embodiment, the interpupillary distance adjusting means 17 is configured based on a method of adjusting the interpupillary distance by parallel movement.

For example, as shown in FIG. 18, the interpupillary distance adjusting means 17 is attached to the fixing member 12 fixed to the main body of the stereoscopic image apparatus.
Alternatively, an operation fixing member 12a necessary for attaching stereo pair positioning means for positioning a stereo pair 13 (not shown) at a predetermined position is attached.
For example, as shown in FIG. 19, the operation fixing member 12a is a rotary dial operation unit 17b, 20 (FIG. 1) operated by the interpupillary distance adjusting means 17 and the stereo pair positioning means.
8) and a shaft fixing means formed in a fork shape with a hole and a tip in order to fit and support the shaft.

Therefore, in the present embodiment, as shown in FIG. 18, fork-shaped shaft fixing means provided at the tip of the operation fixing member 12a, for example, the second reflecting mirror 16 as the interpupillary distance adjusting means 17 is used. A rotary dial operation unit 17b used to adjust the interpupillary distance within a predetermined range is rotatably supported, and screws on the left and right sides of the dial operation unit 17b are, for example, screwed in different directions from each other. Are formed integrally so as to protrude, and the dial operating portion 17b
The shaft is fixed to the rotating shaft.

That is, the screws arranged opposite to the dial operating portion 17b are interlocked with the rotation of the dial operating portion 17b by, for example, rotating the dial operating portion. The interpupillary support member 17a, which is configured to be screwed, can move at the same level in different directions by screwing the screws threaded in different directions. In addition, the dial operation unit 1
7b, the interpupillary support members 17a on both sides
The rotation stopper pin 17d is fixed to the shaft fixing means so as not to rotate, and is mounted on the interpupillary support member.

Thus, when the dial operating portion 17b is rotated so as to adjust to a desired interpupillary distance, the pair of interpupillary distance supporting members 17a is moved in accordance with the rotation of the dial operating portion 17b. Can be expanded or contracted horizontally at the same dimensional level with respect to the rotation axis of
The distance between the second reflecting mirrors 16 attached to the lens, that is, the interpupillary distance, can be adjusted.

Therefore, when the stereoscopic image apparatus is used by opening and closing it from the folded state, first, as shown in FIG. 17, a spring structure (not shown) in which the second reflecting mirror 16 is constantly biased outward. ) To open and close with the Z axis as the fulcrum,
Thereafter, the second mirror 16 is locked at a predetermined angle with respect to the main body by the locking means 16b of the mirror fixing member 16a. As a result, the positioning of the second mirror 16 can be performed automatically. Then
As shown in FIG. 18, a dial operation unit 17b as an interpupillary distance adjusting means 17 of the second reflecting mirror 16 arranged at a predetermined angle
Is rotated according to the eye width of the observer, so that the second reflecting mirrors 16 attached on both sides can be translated at the same level (dimension), that is, the desired eye width of the observer is obtained. be able to.

On the other hand, in the stereo pair positioning means, like the fixed type stereoscopic image apparatus in the first embodiment, for example, a stereoscopic image is obtained so that an observer observes the stereoscopic image apparatus and obtains an optimum stereoscopic image. Pair 13 (FIG. 1
4) along the guide frame member 14a (see FIG. 14).

Therefore, in the present embodiment, as a stereo pair positioning means, for example, as shown in FIG. 18, a dial operating portion 20 as a stereo pair positioning means is fitted into a hole of the operation fixing member 12a and supported by the shaft. The dial operating unit 20 is formed in a cam structure having a joining portion 20a for joining the stereo pair 13 as shown in FIG. 20, for example. 13 can be slid, and the stereo pair 13 can be positioned at a desired position. The joint 20a of the dial operating unit 20 also has a function as a stopper member for roughly positioning the stereo pair 13 when inserting the stereo pair 13 into the stereoscopic image device 11.

Next, the operation of the correcting means for correcting the optical system according to the above-described eye width adjusting means will be described in detail with reference to FIG. The optical system on one side of the left eye will be described to simplify the description. Generally, the human eye width is about 55 mm to 75 mm, and for example, from an observer having a reference eye distance of 60 mm, for example, 75 m
When an observer having an interpupillary distance of m performs stereoscopic vision using the stereoscopic image apparatus according to the present embodiment, first, as described above, using the interpupillary distance adjusting means 17 shown in FIG.
The interpupillary distance is expanded so that the reflecting mirror 16 has a distance dimension of one eye of 37.5 mm, for example. In this case, the second reflecting mirror 1
The interpupillary support member 17a to which the eyepiece 6 is attached moves parallel to a position where the interpupillary dimension of one eye becomes 37.5 mm.

At the same time, the interpupillary support member 17
The rotation support member 14 to which a is attached (see FIG. 1)
However, in conjunction with the interpupillary distance support member 17a, the pivot member rotates about the point F of the fixing member 12 shown in FIG. For example, taking the configuration of the left-eye side optical system reflection means as an example, as shown in FIG. 21, the eye width adjustment means 17 adjusts the position of the second reflection mirror 16 from a reference position of 30 mm to 37.5 mm as shown in FIG. In other words, all the optical system reflecting means (including the second reflecting mirror 16) arranged and positioned on the rotation support member 14 via the link mechanism are moved. It is possible to rotate around a point F (point F in FIG. 21) as a fulcrum.

By the way, the correcting means in the optical system reflecting means according to the interpupillary distance is, for example, as shown in FIG. 21, the center position of the stereo pair 13 is set to the point F, and the point F is used as a fulcrum. By rotating the first reflecting mirror 15 and the second reflecting mirror 16 under these arrangement conditions, the left image 13a of the stereo pair 13 can enter the left eye without vignetting, The eye satisfies the arrangement condition of the optical system reflecting means that enables the stereoscopic vision, so that the optical system can be corrected according to the interpupillary distance.

Therefore, according to the correcting means based on the principle of such an optical system, even when the eye width adjusting means 17 (see FIG. 18) adjusts to a desired eye distance, the optical system corresponding to the eye distance is adjusted. First reflecting mirror 15 as reflecting means
In addition, it is possible to obtain an optimal arrangement configuration for enabling the second reflecting mirror 16 to be stereoscopically viewed, that is, to correct the optical system according to the interpupillary distance adjustment.

As described above, according to the present embodiment, since the stereoscopic image apparatus is configured as a foldable type using a link mechanism, it is convenient for carrying, for example, by carrying, etc., and at a location desired by the user. You can enjoy stereoscopic viewing. Further, for example, even when a plurality of observers with different interpupillary distances perform observation (stereoscopic vision), the observer is configured using the interpupillary distance adjusting means, and therefore can be adjusted according to the interpupillary distance of each observer. In addition, the optical system can be corrected according to the interpupillary distance adjustment, so that all persons can perform stereoscopic vision. Further, since the stereo pair is used as in the first embodiment, the user can easily create the stereo pair and can easily perform positioning with respect to the apparatus.

In this embodiment, the correction means of the optical system according to the interpupillary distance is such that the second reflecting mirrors are moved in parallel, and in conjunction therewith, the center point of the stereo pair is used as a fulcrum to reflect the optical system reflecting means. Although the description has been given of the case where the correction is performed by rotating all of them, for example, the first reflecting mirror is rotated so as to adjust the interpupillary distance and enable the stereoscopic vision.
The arrangement condition of the reflector may be changed.
The correction of the optical system according to the interpupillary distance may be performed using a lens or the like.

In this embodiment, the second reflecting mirror is arranged at a predetermined angle by the spring structure and the locking means from the folded state to the open / closed state (during use). However, for example, a bar code indicating personal information such as image size or interpupillary size is provided at the tip of the insertion side of the stereo pair, and the bar code is read when the stereo pair is inserted into the stereoscopic image device. A sensor is provided on a stereo pair positioning means or a guide frame member that comes into contact with the stereo pair, the second reflecting mirror angle is automatically set electrically, and the arrangement condition of the optical reflecting means according to the image size. You may make it become.

Further, in this embodiment, the optical axis is corrected by using an eyepiece lens (see FIG. 18) or a lens such as a loupe so that an observer using, for example, spectacles can observe with the naked eye. The arrangement condition of the optical system reflecting means may be changed according to this case.

Next, FIG. 22 shows an example in which a foldable three-dimensional image device constituted by using a link mechanism is further improved.

FIGS. 22 to 25 show a fourth embodiment of a stereoscopic image apparatus according to the present invention.

When the stereo pair 13 is inserted, the guide frame member 12a is inserted into the groove 12b and is inserted along the guide frame member 12a. The setting is to be performed.

On the other hand, as the schematic structure of the folding type, the link mechanism in the third embodiment (see FIG. 14) has been improved so that the number of parts is reduced and the cost is reduced. For example, as shown in FIG. 22, three types of first to third rotating members 14a, 14b, and 14d composed of at least a pair of upper and lower members rotatably attached to a predetermined position of the fixed member 12 are provided. ing. The first rotating member 14a and the second rotating member 14b
Is configured to have a hinge structure with a junction point R,
By utilizing the link mechanism having such a hinge structure, for example, the reflector supporting member 15a to which the first reflector 15 is attached can be folded.

The foldable structure using such a link mechanism is arranged, for example, as shown in the figure, at a predetermined width in front of the fixing member 12, and is provided so as to be rotatable around the Q point as a fulcrum.

Therefore, in the link mechanism of the present embodiment, when compared with the link mechanism of the third embodiment, the third rotation member 14c shown in FIG. The folding operation can be obtained in the same manner as in the embodiment, that is, the number of components such as the rotation instruction member 14 and the third rotation member 14c (the components constituting the link mechanism of the third embodiment shown in FIG. 14) is reduced. By reducing the cost, the configuration can be made inexpensively, so that it is more practical than the third embodiment.

By the way, the interpupillary distance adjusting means and the correcting means in this embodiment are the same as the correcting means of the third embodiment, which performs the correction according to the interpupillary distance by rotating all the optical system reflecting means as described above. In contrast, for example, as shown in FIG. 23, only the second reflecting mirror 16 is moved in a predetermined direction to correct the optical system according to the adjustment of the interpupillary distance.
Also in this case, the distance to the assumed fusion point is 500 mm.

First, the first reflecting mirror is not moved, and only the second reflecting mirror 16 (see FIG. 23) is adjusted.

A claw (not shown) is provided for joining with the locking portion 16c as locking means for locking the second reflecting mirror 16 at a predetermined angle.

On the other hand, as an operation unit of the interpupillary distance adjusting means 21 by the observer, a rotary interpupillary distance adjusting operation unit 21a is provided as shown in FIG. It is configured to mesh with the interpupillary distance adjusting operation section 21 and move in opposite directions and at the same distance dimension. That is, the left second reflecting mirror 16 is connected to the upper interpupillary distance adjusting support member. 21b, and the interpupillary adjustment support member 21c is provided with an interlocking member 22a that meshes with and interlocks with the interpupillary distance adjustment operation unit 21a, thereby allowing the interpupillary distance adjustment operation unit 21a to rotate. It is possible to move the second reflecting mirror 16 to the corresponding left side.
