Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for taking a stereo picture, and more particularly to an apparatus for taking a stereo picture using a simple camera called a lens-fitted film.

[0002]

2. Description of the Related Art As is well known, a stereo photograph is a pair of photograph prints of the same subject, which are taken at different positions in the left-right direction, using a viewer (101) as shown in FIG. By observing, you can see a stereoscopic image with depth.

In the viewer (101) of FIG. 5, a pair of left and right photographic prints (103L) and (103R) are mounted side by side on a frame (102), and a pair of left and right transparent lenses (104L) (104R) are attached. , Each photo print
(103L) and (103R) are installed toward the center.

The images of a pair of photographic prints (103L) (103R) were taken with the same subject at different positions on the left and right, and both eyes were placed on the respective perspective lenses (104L) (104R). By observing the corresponding images, the left and right images are combined and visually recognized as a stereoscopic image.

To take such a stereo picture,
Generally, a stereo camera (106) as shown in FIG. 6 is used.

This stereo camera (106) has a pair of left and right photographing lenses (108L) (108R) on the front of a horizontally long body (107).
Are installed with their optical axes in parallel.

A finder (10) provided at an appropriate position of the body (107)
9) Determine the shooting position and press the shutter release button.
Press down (110) and a pair of shooting lenses (108L) (108R)
The shutter device attached to the camera simultaneously opens and closes, and the images of the respective photographing lenses (108L) and (108R) are photographed on the film.

Further, as a means for taking a stereo picture with a normal camera having only one taking lens without using a special camera for taking a stereo picture as shown in FIG. There is also known a method in which the position of is moved to the left and right and the image is taken twice.

[0009]

A stereo camera as shown in FIG. 6 requires two sets of taking lenses, and
Since it is necessary to simultaneously operate the shutter devices attached to the respective photographing lenses by operating a common release button, there is a problem that the mechanism is complicated and the cost is high.

The means for taking a picture twice by shifting the position to the left and right using a normal type camera can be applied only to a still life picture in which the object is stationary, and a moving object is taken as a stereo picture. There is an inconvenience that you cannot do it.

On the other hand, in recent years, a simple camera called a film with a lens has come into wide use, and it has become possible to easily take a snap photograph.

This simple camera is known, for example, from Fuji Photo Film Co., Ltd., "Fujicolor Photograph," and Konica Corporation, "Photographable Konica."
It is a so-called disposable inexpensive camera.

It is an object of the present invention to provide an apparatus which can easily take a stereo picture by using two simple cameras of this type.

Install (58) directly above the shutter release button (15) of the two simple cameras (11) and (12).

When the film winding knob (16) of the two simple cameras (11) and (12) is operated to charge the shutter, the composition is determined by the viewfinder window (14), and the lever plate (56) is pushed down. As in the first embodiment, a stereo photograph of the same subject taken from positions separated in the left-right direction can be obtained.

In the above-mentioned second embodiment, "magic chuck" is applied to both the means for locking the stacked edges of the holding sheet (40) and the means for attaching the shutter operation lever (54). However, other means may be used, such as the well known snap hooks.

In addition, when not taking a stereo photograph, each simple camera (11) (12) is connected to the frame (20) and the holding sheet.
It goes without saying that if it is removed from (40), it can be used individually as a normal camera.
