Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stereo photographic viewer used for observing a stereoscopic image from a pair of print photographs.

[0002]

2. Description of the Related Art A pair of print photographs are obtained from a film photographed with a parallax in the left-right direction, and when these print photographs are observed with both eyes at the same parallax as at the time of photographing, a stereoscopic image can be obtained. Are known. A stereo photographic viewer is used so that this stereoscopic view can be performed easily.

A conventional stereo photographic viewer includes a print photograph holding portion for holding a left-eye observation print photograph and a right-eye observation print photograph side by side, and a pair of observation windows provided in front of the print photograph holding portion. It has and. These observation windows are for directing the left eye gaze of the observer to the screen center of the left eye observation print photograph, and for directing the right eye gaze to the screen center of the right eye observation print photograph. A lens that serves as a loupe is fitted into the window if necessary.

[0004]

However, in order to perform stereoscopic viewing using the conventional stereo photographic viewer,
The left-eye image and the right-eye image must be photographed as individual photographing frames, and two print photographs obtained by individually performing the print processing must be set in the holding unit. Therefore, there is a problem that the left-eye and right-eye print pictures are set in the viewer by mistakenly inserting them into the left and right, and one of the print pictures is scattered and stereoscopic viewing becomes impossible.

Images for the left eye and images for the right eye are photographed in one photographing frame, and the left eye and the right eye are photographed in one print photograph without changing the printing process so far. In order to be able to print both images at the same time, the shooting optical axes should be crossed at the time of shooting, and the left eye on the film,
It is necessary to switch the images for the right eye before shooting. Although a camera for stereo photography having such a device is known, there is a drawback that the camera becomes large in size because a mirror must be used in order to intersect the optical axes of photography.

The present invention has been made in order to solve the above-mentioned problems of the prior art, and does not complicate the structure of the camera at all, and can be used for left-eye observation and right-eye observation by ordinary print processing. It is an object of the present invention to provide a stereo photographic viewer that enables normal stereoscopic viewing even if an image is obtained as one print photograph.

[0007]

In order to achieve the above object, a stereoscopic photographic viewer of the present invention holds one stereo print photograph on which a left eye observing image and a right eye observing image are printed. It is composed of a print photograph holding portion and a single observation window provided in front of the print photograph holding portion and at a position overlapping with substantially the center of the print photograph. Further, by connecting two sets of such stereo photographic viewers, stereoscopic viewing of two types of photographic images becomes possible.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 3 shows a stereo camera which is supposed to be observed by using the stereo photographic viewer of the present invention.
The outline of the internal structure is shown in FIG. On the front surface of the stereo camera 2, two taking lenses 3 and 4 are arranged side by side in the horizontal direction, and the distance between them is, for example, an average human eye width (about 65 mm).

As shown in FIG. 4, shutters 5 and 6 are provided behind the taking lenses 3 and 4. When the shutter button 7 is pressed, these shutters 5 and 6 are opened and closed at the same time. As a result, the luminous flux from the subject S is taken by the photographing optical axis 3 respectively.
The left eye image 10a and the right eye image 10b having parallax are photographed side by side on the film 8 after being incident on the photographing lenses 3 and 4 in accordance with a and 4a. The image 1 for the left eye
0a and the image for right eye 10b are respectively photographed in half size, and when these images are combined, they become 35 mm full size.

From the film thus photographed, a full-size printing process is carried out using an ordinary printer. In normal printing, one printing lens is used to print one full-size screen, and the resulting print photograph is as shown in FIG. That is, the image for left eye 10a
A single stereo print photograph 12 is obtained in which the left-eye observation print image 12a of FIG. 2 is arranged on the right side and the right-eye observation print image 12b of the right-eye image 10b is arranged on the left side.

The stereo print photograph 12 obtained as described above is set on the stereo photograph viewer 15 according to the present invention as shown in FIG. This stereo photographic viewer 15 is integrally molded of plastic and has a gutter-shaped rail 16 which serves as a holding portion of the stereo print photographic 12 on one end side, and an observation window 17 on the other end side which supports these. It is configured to be connected with. A lens 19 is fitted into the observation window 17 and acts as a loupe during observation. The lens 19 may be integrally molded.

The observation window 17 is separated by a distance that makes it easy to observe the stereo print photograph 12 according to the focal length of the lens 19, and is provided at a position just overlapping the center of the stereo print photograph 12. Therefore, the stereo print photograph 12 is inserted into the rail 16 and the lens 1
When viewing the stereo print photograph 12 with the left eye 21 and the right eye 22 through 9, the left eye gaze 21a and the right eye gaze 22a intersect at the observation window 17, and the left eye 21 observes the left eye observation print image 12a. The right-eye observation print image 12b is observed by the right eye 22.

As described above, the stereo photographic viewer 1
5, the left eye observation print image 12a and the right eye observation print image 12b are arranged side-by-side in the left and right side of the stereo print photograph 12, and the binocular gaze is observed through the observation window 17
Normal stereoscopic vision is possible by crossing and observing. Moreover, such a stereo print photograph 12
Can be photographed by a camera with a simple structure that does not require a mirror, and the printing process can be performed as usual, so that stereoscopic viewing of photographic images can be enjoyed at low cost. Even if the lens 19 is omitted, the image can be viewed stereoscopically.

FIG. 2 shows another example of the present invention. The stereo photo viewer 24 is provided with a mount 27 that allows the stereo print photo 12 obtained as described above and another stereo print photo 25 obtained in the same manner to be held by, for example, an adhesive tape. ing. A valley fold line 27a is provided in the center of the mount 27, and rising pieces 28 and 29 are continuously provided on the mount 27 via valley fold lines 27b and 27c. At the center of these rising pieces 28 and 29, there are observation windows 30 and 3 in which lenses are fitted.
1 is formed.

When stereoscopically viewing an image with the stereo print photograph 12, as shown in FIG.
The backing sheet 27 is bent from 27b, and the rising piece 28 is set so as to be parallel to the stereo print photograph 12.
In this state, the stereo print photograph 1 through the observation window 30
As seen from FIG. 2, stereoscopic viewing of an image can be performed in exactly the same manner as in the above embodiment. Also, the other stereo print photo 2
When the image is stereoscopically viewed with 5, the valley fold line 27
Bend from a, 27c, from the back side of this figure, the observation window 3
1 through the stereo print photograph 25 with both eyes. Of course, a plastic sheet can be used instead of the mount 27.

[0016]

As described above, according to the viewer for stereo photography of the present invention, one stereo print photograph obtained by printing the left eye observation print image and the right eye observation print image is observed. Since we have made it possible to observe both eyes through the window, it is not necessary to switch between the left-eye observation image and the right-eye observation image when taking a picture as in the conventional way, and the camera structure becomes simple. It will be possible to avoid the increase in size. Further, since the stereoscopic viewing can be performed only by performing the usual print processing from the film thus obtained, the printing system need not be changed at all, and the stereoscopic viewing of the photographic image can be performed at low cost. Furthermore, since the left-eye observation print image and the right-eye observation print image can be combined into one stereo print photograph, the set operation at the time of observation is easy, and one of the print images is dissipated for stereoscopic viewing. The inconvenience of being unable to do so can be eliminated.
