Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a stereoscopic print photograph, a stereoscopic print photograph producing apparatus, and a stereo viewer capable of performing stereoscopic vision by observing with both eyes at the same time.

[0002]

2. Description of the Related Art Japanese Unexamined Patent Publication No. 53-1530 and Japanese Utility Model Laid-Open No. 54-
In Japanese Patent Laid-Open No. 155550 and Japanese Patent Laid-Open No. 62-215938, the same subject has a parallax in the left-right direction.
A method is shown in which one print photograph is created, and these are simultaneously observed with both eyes to reproduce a subject image having a stereoscopic effect. The stereo cameras disclosed in JP-A-53-1530 and JP-A-62-215938 use two sets of photographing lenses and two sets of mirror optical systems, and have two types of parallaxes in the horizontal direction. The left and right sides of the subject image are swapped and then recorded on the photographic film. In this way, by taking pictures with the left and right sides interchanged on the photographic film, the conventional printing system is used as it is during the printing process, and the two types of negative images on the photographic film are lined up on one photographic paper sheet at the same time. If you print
There is an advantage that two printed photographs for stereoscopic viewing can be created as one sheet.

On the other hand, when two kinds of subject images are photographed by the camera disclosed in Japanese Utility Model Publication No. 54-155550, the conventional print system is used, and the left and right sides of the two printed photographs are The situation is the same as when shooting, and normal stereoscopic images cannot be reproduced even if they are observed at the same time. Therefore, when shooting with such a camera, two types of negative images are printed on one sheet of photographic paper with a conventional printing system and then these are separated and left and right are replaced, or left and right are replaced on photographic paper. In addition, it is necessary to print the two negative images individually in the same order as the shooting.

[0004]

However, in the former method described above, the printing process can be made more efficient, but on the other hand, the camera needs two mirror optical systems in addition to the two taking lenses. There is a drawback in that the number of parts and the number of assembling steps increase due to complexity, and the manufacturing cost cannot be reduced. In addition, because it shoots through the mirror optical system, compared to a camera that shoots only through the shooting lens,
Inevitable deterioration of image quality. On the other hand, in the case of the latter method, the camera itself can be simplified, but on the other hand, it takes time and effort to make a print photograph for stereoscopic viewing, and it is difficult to supply the print photograph for stereoscopic viewing at a low cost as it is. In addition, the conventional single sheet has 2
The stereoscopic effect was limited because only one print photograph was created.

An object of the present invention is to solve the above-mentioned problems of the prior art and to produce a stereoscopic print photograph at a low cost, and a method for producing a stereoscopic print photograph. It is an object of the present invention to provide a stereoscopic print photograph creating apparatus to be used and a stereo viewer that allows various stereoscopic effects to be enjoyed.

[0006]

In order to achieve the above object, the method for producing a print photograph for stereoscopic vision according to the present invention achieves the above object by arranging a plurality of subject images having parallax on the same subject in a film at the same time and developing the film. Each of the photographic images obtained by the above is continuously printed on the photographic paper while maintaining the arrangement at the time of shooting. In order to continuously print the photographic images after film development on the photographic paper while maintaining the arrangement for each photographing, for example, a printing lens individually provided for each photographic image can be used. Further, when increasing the enlargement magnification of the print photograph, it is only necessary to shift the printing lens, which is separately provided, parallel to the printing paper surface and tilt the central optical axes of the photographic screens in directions away from each other as necessary.

Further, in the stereoscopic print photograph producing apparatus of the present invention, in an apparatus for enlarging and printing from a plurality of original images photographed from two or more different viewpoints, only the original images corresponding to the plurality of projection lenses are converged and projected. It is divided to do. According to another aspect of the present invention, there is provided a stereoscopic print photograph producing apparatus, wherein a plurality of original images are illuminated by the same light source and a plurality of projection lenses are respectively provided in an apparatus for enlarging and printing from a plurality of original images photographed from two or more different viewpoints. It is partitioned so that only the corresponding original image is converged and projected, and the mutual spacing of each lens can be adjusted according to the change of the enlargement ratio.

Further, the stereo viewer of the present invention is adapted to slidably support a print photograph so that an arbitrary pair can be selected from a plurality of photographic images for observation. In addition, when selecting an arbitrary pair that is not adjacent to each other, an opening is provided to allow an unnecessary photographic image to escape.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. 3 and 4 show an example of a camera used for photographing to obtain a print photograph for stereoscopic vision according to the present invention. This camera is basically the same as the lens-equipped film unit that is already widely marketed by the applicant under the product name such as "Sharp Run", and the 135 type film 2 is pre-installed in the main body 4 together with the cartridge 3. It has been stored. When the dial 5 is operated to wind up the film after one shot is taken, the exposed film 2 is wound into the cartridge 3 and the unexposed film is pulled out from the film roll chamber 6 to the exposure position. Then, after all the frames of the film 2 have been photographed, the system for directly submitting the whole body 4 to the developing shop is adopted, and the negative film and the print photograph are returned to the user. By adopting such a system, the user is not required to perform a film loading operation, a film rewinding operation after use, and an exposed film removal operation, and anyone can easily take a picture. .

On the front surface of the body 4, four photographing lenses 8 are provided.
a, 8b, 8c, and 8d are arranged in a straight line with a distance D between the optical axes. The value of the distance D between the optical axes is 1
The range of 6 to 20 mm, for example, about 18 mm is preferable.
These taking lenses 8a, 8b, 8c and 8d have the same optical specifications such as the focal length (preferably in the range of 20 to 40 mm) and the same distance from the film surface. Shutters 9a, 9b, 9c and 9d are provided behind the taking lenses 8a, 8b, 8c and 8d, respectively, and the exposure chambers behind them are provided with partition walls 10a, 10b and
It is divided by 10c. The partition walls 10a and 10c divide the exposure range for one full-size frame into two at the center, and the half-size exposure frames 11a, 11b, and
11c and 11d are formed. When the shutter button 12 is pressed, the shutters 9a, 9b, 9
c and 9d are opened and closed at the same time, and the photo lens 8 is attached to the film 2.

An opening 25a having a size of about 85 mm × 85 mm is formed, and similarly to the conventional printer, when the film 2 is transferred, the photographic paper transfer mechanism 26 is driven to open the photographic paper 18 at the opening 25a.
The print process can be continued by sending the print data according to the width of a.

As shown, the print lenses 24a, 24
b is shifted so as to be separated from each other in the arrangement direction of the photographic images 15a and 15b. This shift amount is determined according to the print magnification, and as a result, the photographic image 15
The screen centers of a and 15b are separated on the photographic printing paper 18. The partition plate 22 provided between the printing lenses 24a and 24b prevents the printing lights of the photographic images 15a and 15b from mixing with each other. As described above, according to the conventional printer, the photographic images 15a, 15b, 15c, 15d can be obtained by performing the printing process twice.
It is possible to print on the photographic paper 18 with the same magnification while maintaining the arrangement of No. FIG. 2 shows a print photograph obtained in this way, in which the taking lens 8a

8d are printed in the arrangement at the time of shooting. After the printing process, the photographic printing paper 18 is cut by the cut lines 29, and therefore four kinds of prints 28a, 28b, 28c, 28d are arranged on one service print 28.

FIG. 5 shows a simple viewer for observing one service print 28 created as described above. In the viewer 30, for example, the mount 31 is bent at two places, two Fresnel lenses 32a and 32b are attached to one start-up piece 34, and the support portion 33 of one service print 28 is attached to the other start-up piece 35. Is provided. Each of the Fresnel lenses 32a and 32b is used as a loupe, and is provided at a position corresponding to an average eye width of an observer of about 63 mm. One service print 28 is slidably supported by the support pair 33. And the viewer 30
Any adjacent pair (printed photos 28a, 28b, printed photos 28b, 28c, and printed photos 28c, 28c,
28d) is selected, and the selected pair is viewed as a stereoscopic photograph.

For example, as shown in FIG. 5, one lens 32a directs the left eye's line of sight to the left eye print photograph 28c, while the other lens 32b directs the right eye's line of sight to the right eye print photograph. 28b. When such a viewer 30 is used to observe the left-eye print photograph 28c with the left eye and the right-eye print photograph 28b with the right eye independently, the images of the respective print photographs 28b and 28c due to the binocular parallax effect. Is perceived in a state of being combined into one image with a stereoscopic effect. Further, by sequentially looking at the adjacent pairs from the ends of the print photographs 28a to 28d, it is possible to obtain the feeling of looking around the subject.

In the illustrated example, the left-eye print photograph 2 is shown.
8c and screen center distance D between right eye print photograph 28b
1 shows the case where 1 is smaller than the average pupil distance, and the distance D0 between the optical axes of the lenses 32a and 32b is matched with the pupil distance, but when the distance D1 between the screen centers is larger than the pupil distance. Is the lens 32a, 32b itself provided at a position corresponding to the pupil distance, but the distance D0 between the lens optical axes is larger than the pupil distance so that the left and right lines of sight are centered on the screens of the print photographs 28b, 28c. It is effective to make it easy to point to.

6 and 7 show another example of the viewer 36. This viewer 36 has one service print 28
An arbitrary pair is viewed as a three-dimensional photograph among the above print photographs 28a to 28d. For example, print photo 2
When viewing 8a and the print photograph 28d as a stereoscopic photograph, the unnecessary print photographs 28b and 28c between the print photograph 28a and the print photograph 28d are allowed to escape from the opening 37, and the line of sight of the left eye is given to one lens 32a. The lens 32b on the other side directs the line of sight of the right eye to the print photograph 28d for the right eye. According to this, by selecting an appropriate pair according to the perspective of the photographed subject, the print photographs 28a to 28
It is possible to see a stereoscopic image in which the stereoscopic effect is emphasized, as compared with a method in which adjacent pairs are sequentially viewed from the end of d.
For example, in one service print 28 of a distant subject, the print photos 28a and 28d at both ends are selected, and in one service print 28 of a distant subject, the center print photos 28b and 28c are selected. Is to be selected.

A print pressing portion 38 is provided in front of the opening 37 in order to prevent the print photograph from bulging due to escape. Further, the left and right partition walls 39 are provided between the print pressing portion 38 and the one rising piece 34.

The camera shown in FIG. 9 can also be used for photographing for obtaining the above-mentioned stereoscopic print photograph. In this camera, four photographing lenses 8a, 8b, 8c, 8d are arranged on the front side in an arc shape centered on a predetermined subject distance P.
Further, in order to equalize the distances between these taking lenses 8a, 8b, 8c, 8d and the film surface, the shutter 9
a, 9b, 9c, 9d and exposure frames 11a, 11b, 1
Both 1c and 11d are arranged in an arc shape centered on the subject distance P. According to this, if the subject distance P is set to a distance at which the user frequently shoots, compared to the camera shown in FIG. 4, all the subjects are recorded in the center of the screen on the film 2, and the viewer shoots a stereoscopic photograph. Is easier to see.

Further, FIG. 10 shows a camera in which four photographing lenses 8a, 8b, 8c and 8d are arranged linearly like the camera shown in FIG.
The optical axes of a, 8b, 8c and 8d are radially shifted around a predetermined subject distance P. According to this, the camera shown in FIG. 4 can be manufactured at a low price without complicating the structure of the camera body 55, and the subject is recorded on the film 2 at the center of the screen, so that the viewer can easily see the stereoscopic photograph. Become.

Since the printer shown in FIG. 1 can print both the photographic images 15a and 15b, which are one full-frame image, at the same time, the conventional printer is used to transfer the film 2 and the photographic paper 18. The film 2 is advantageous in that it can be carried out with the same control as the above.
The printer shown in FIG. 11 can also be used when the transfer control method of the photographic printing paper 18 can be changed.
This printer has four printing lenses 60a to 60d arranged, and one for four photographic images 15a to 15d.
A set of stereoscopic print photographs are printed at the same magnification at the same time.

Further, in the above-mentioned camera, the four photographing lenses 8a to 8d are provided as an example. However, in the camera according to the present invention, the number of photographing lenses is 5 or more in order to obtain many photographic images having different parallaxes. May be. In the case of a film photographed by a camera in which two photographing lenses are arranged on the left and right, a printer optical system as shown in FIG. 12 can be used. This print optical system is a film 70
The above two types of photographic images 70a and 70b are printed on the photographic paper 18 by the common printing lens 71 to form a left-eye print photograph 72a and a right-eye print photograph 72b. In this print optical system, a partition plate 73 and a roof mirror 74 are used to separate the photographic images 72a and 72b. Further, the left and right arrays of the photographic images 72a and 72b are interchanged and the mirrors 75a and 7b are arranged to prevent the images from becoming mirror images.
5b is used. According to this, like the printer shown in FIG. 1, when printing from a plurality of photographic images, by simultaneously printing so that the left and right arrangements thereof are not interchanged, it is possible to transfer a film or printing paper conventionally. It can be controlled in the same manner as a printer, and it is possible to provide a stereoscopic print photograph at a low cost while suppressing the print cost.

The present invention has been described above with reference to the illustrated example. By making the screen sizes of the two types of photographic images 15a and 15b to be photographed on the film 2 half size as in the above embodiment, Although there is an advantage that a print photograph for stereoscopic viewing can be obtained by using most of the conventional full-size printers, in implementing the present invention, the screen size of the photographic images 15a and 15b and the print photograph 28 is However, the present invention is not necessarily limited to the one described in the above embodiment.
