After re-editing the two left and right films that were photographed into a single film 31 as shown in Figure 5 with the left and right centers slightly shifted and the top and bottom as one, the filter 3 with diagonal lines as shown in Figure 6 is created. The image of the film 31 projected by the camera 4 equipped with the camera is sent to the left and right eyes with the center slightly shifted through the filter glasses 5 with diagonal lines as shown in FIG. It made me feel.

<Problems to be Solved by the Invention> However, in order to take pictures with the camera 1, the center position of the master lens 28 of one camera must always be aligned vertically. It is necessary to adjust the center position of the lens by looking through the Faing-25 alternately, which makes the adjustment troublesome, and there are also problems in that the cost is high because two cameras are used.

Furthermore, during projection, since the center distance between the two master lenses 28 is large as shown in FIG. The problem is that I get a headache when I watch it.

A camera consisting of a camera body consisting of a device and a camera box in which they are installed, and a lens section having one end attached to the camera body and having two master lenses at the other end, the camera box having a is provided with a fin having a ridge in the center for adjusting the center position of the master lens, and the lens part is configured to connect the two master lenses slidably attached to the guide rail, and the master lens. The center position of the adjustment scale is moved via a screw in accordance with the adjustment scale, two sets of field lenses are provided on the film side corresponding to the master lens, and the direction in which the image is projected by the field lenses is adjusted. a first projection mechanism consisting of a pair of mirrors that converts the image; a second projection mechanism consisting of a pair of upper and lower mirrors that projects the image from the first projection mechanism as an integrated image of the upper and lower sides; A relay lens that receives the image from the projection mechanism and these are installed inside.
This is a three-dimensional video photographing camera characterized by comprising a lens box and a lens box, and projecting an image from the relay lens onto a film on a film mounting surface.

<Example> Hereinafter, an example of the present invention will be specifically described based on the attached drawings.

As shown in FIGS. 1(A) and 1(B), the camera box 6 of the camera body 32 is provided with a film mounting surface 7 on which the film 8 runs, and the film mounting surface 7 is located on the object side. A shutter device 9 is installed inside the camera box 6, and a fine lens 10 on which the image on the film mounting surface is projected is provided on the eye side of the camera box 6.
As shown in the figure, scales 21 and 22 for adjusting the center position of the master lens are carved.

Further, a lens section 33 is provided on the objective side of the camera box 6.
A lens box 11 is attached, and the lens box 1
On the objective side of 1, a pair of left and right master lenses 12 and 13 are set at a center position of approximately 63 mm on the left and right sides, which is equal to the distance between human eyes, and on the top and bottom, shifted at appropriate intervals according to the size of the film. has been done. Here, the master lens 1
2 and 13 are slidably attached to guide rails 34 and 35, and are moved by screws in the center position up and down and left and right by adjusters 36 and 37.

Further, two sets of field lenses 14.15 are arranged on the film side corresponding to the master lenses 12, 13, and the image projection by the field lens 14.15 is provided on the film side of the field lenses 14.15. A first projection mechanism 1 consisting of a beam consisting of a set of mirrors that change direction.

It is arranged so as to form an angle of 45° with respect to the central axis of.

Also, on the central axis of the lens box 11 corresponding to the first projection mechanism 16, 17 is a second mirror consisting of a pair of upper and lower mirrors that projects the image from the first projection mechanism as an upper and lower integrated image. Projection mechanisms 18 and 19 are provided. here,
The second projection mechanism 18, 19 is arranged such that a mirror surface having a hyperplane faces perpendicularly to the mirror. Further, on the central axis of the lens box 11 on the film side of the second projection i4 [118, 19, the second projection mechanism 1
A relay lens 20 is provided to receive the image from 8.19.

Next, an example of use of the present invention will be explained as follows.

As shown in FIG. 1(a), the left and right master lenses 12
．． The images B and C of the object entered from 13 first pass through field lenses 14 and 15, and due to the reduced imaging power of the field lenses, images B, C, without aberration are formed.

Further, the projection direction of the images B, C, is transformed by a first projection mechanism 16, 17 consisting of a mirror with a hyperplane mirror surface, and the projection direction of the images B, C, is transformed by a second projection mechanism 18, 19 consisting of a similar mirror. The image is sent to the relay lens 20 as an integrated upper and lower image, and its brightness is doubled by the relay lens 20, and the amount of light lost by the field lens and mirror is compensated for, resulting in a clear image B, Ct without any aberrations. The upper and lower images are formed integrally on the film mounting surface 7.

Then, as shown in FIG.
After adjusting the adjusters 36 and 37 so that they are centered at 1.22 degrees, the shutter device 9 is activated to take a picture, and the horizontal center distance between the two master lenses is approximately 63 degrees, which is equal to the distance between human eyes. Therefore, photography is performed without the left-right reversed portion as shown in FIG. 4, and an image close to natural vision is obtained.

<Effects of the Invention> As described above, in the present invention, by adjusting the center positions of the two master lenses using the adjuster according to the fine adjustment scale, the left and right images from the left and right master lenses of one camera can be adjusted. The structure is such that the upper and lower images are formed as one image on the film surface, making it easier to make adjustments during shooting, simplifying the structure and lowering costs. It has the effect of eliminating cancer.

In addition, as the image transmission means, we use a projection mechanism consisting of a field lens with high imaging power and a mirror with a hyperplane with little aberration, and a relay lens that doubles the amount of light, making it possible to provide clear images without aberrations. It has the effect of being able to do it.
