Abstract

PURPOSE:To record both right and left images which are free from positional deviation by projecting simultaneously the image for the right eye and the image for the left eye of a stereoscopic film and deflecting both projection light to image superposedly the right and left eye images. CONSTITUTION:The projection of only the desired images L, R for the right and left eyes of the stereoscopic film P is made possible by a slit plate 16. Both projection light L' (A, B, C) and R' (a, b, c) are made incident on a polyhedral prism 2 having an even number of faces. Both light L' and R' are delfected in the prism 2 and the images are formed via a lens 3. Filters 4, 5 for red and blue are provided between the prism 2 and the lens 3 to color the image projection light L' for the left eye to red and the image projection light R' for the right eye to blue. The images are recorded to a color recording medium in an imaging position Q.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a method and apparatus for recording stereoscopic photographs.

[Conventional technology]

Stereo photography uses a stereo camera equipped with two equal lenses spaced apart by the distance between the human eyes (approximately 65 mm), and takes pictures of the left and right sides of the subject at the same time, as shown in Figure 2 (
In the case of photographing with 102 cameras as shown in (a), and in the case of shooting with 102 cameras as shown in (b), one camera 1° uses a stereo adapter 11 to record images for the right eye and images for the left eye on the film 1. There are cases where the images are taken in parallel.

Regardless of the shooting method, the recording method is to mount both images R in parallel, as shown in Figure 3.
The mount 12 is generally observed using a viewer 13.

However, a viewer must always be provided at the observation location, which is very cumbersome.

Therefore, as shown in FIG. 4, the right eye image and the left eye image are superimposed and printed on a sheet of color photographic paper 14 through filters 13a and 13b of different colors, and as shown in FIG. , these two images R9L printed in different colors are passed through the filter 13). 13
Another method is to observe the image using glasses 15 containing the letter b.

However, this method prints the right-eye image and the left-eye image alternately on a single sheet of color photographic paper, so in order to obtain a clear three-dimensional image, the angle of view of both images R and L must be correct. Adjustments (position/tilt adjustments) must be made. However, skill is required to accurately adjust this angle of view.

[Problems to be Solved by the Invention] Taking the above points into consideration, it is an object of the present invention to provide a recording method and apparatus in which left and right images RL are superimposed without any positional deviation.

[Means to solve problems]

In order to achieve the above object, the recording method of the present invention projects a right-eye image and a left-eye image on a three-dimensional film at the same time, deflects both projected lights, and superimposes them at the same position via a lens to form images. At the same time, both projected lights are passed through filters of different colors, and the images are recorded on a color recording medium.

The device also includes a projector that can simultaneously project a right-eye image and a left-eye image of a three-dimensional film, a deflector that deflects both projected lights, and a deflector that allows both projected lights to pass through. a lens that forms images overlappingly at the same position; a filter of a different color through which both projected lights pass through in areas where both projected lights are separated from each other with a center line as a boundary; and a filter that records the image formation. It consists of a color recorder and a color recorder.

With this configuration, the left and right images with different colors are formed to overlap at the same position, and this formed image is recorded on a color recording medium such as a color slide film, color photographic paper, or a color television camera.

This recording paper is projected and its image is observed, or directly, through glasses made of filters of different colors.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

First, a three-dimensional film P is created in the same manner as conventionally.

This film P may be either a color film or a black and white film, and as shown in FIG.
The images for the left eye may be alternately consecutive, but the images R and L may be only one set.

A slit plate 16 is used on the film P to project desired images for the left and right eyes, and only R is projected on the film P.

C) enters the polyhedral prism 2 with even-numbered surfaces. In this prism 2, both projected lights L' and R' are deflected by a lens 3.
image through. This image formation is both images.

K must overlap, and this is set by appropriately selecting the degree of deflection of the prism 2.

The prism 2 rotates in synchronization with the movement of the film P and serves as a shutter.

Between the prism 2 and the lens 3, there are red and blue filters 4.
5 is provided with the center line α (optical axis) of both projected lights L' and R' as a boundary, and the filters 4 and 5 transform the image projection light L' for the left eye into red and the image projection light for the right eye ' is colored blue.

At the imaging position Q, there is a still camera, a Poloride camera,
Set up a television camera and record the image in color.

The recorded images are images for the left and right eyes, in which R is colored red and blue, respectively, and overlapped.

If this recorded image is projected or printed, and the projected/printed image is observed through glasses with a red filter for the right eye and a blue filter for the left eye, the right eye image K will be displayed using the same color filter. However, each left eye image is confirmed, and the viewer sees it as a three-dimensional image. Depending on the image obtained during this observation,
The colored filters may be reversed for the left and right images.

At this time, normal stereoscopic vision can be achieved by reversing the left and right viewing glasses equipped with red and blue filters.

In the example, filter 4.5 is combined with prism 2 and lens 3.
Although provided in between, there is an area where both projected lights R' and L' are separated from each other with the center line α as a border, for example, lens 3.
and focal point E, etc. Further, the filter 4.5 is not limited to blue or red, but may be of a different color. Additionally, the images may be printed directly onto photographic paper.

〔Effect of the invention〕

This invention is configured as described above, and the left and right eye images are overlapped and formed by deflecting both projected lights.If the degree of deflection is set in advance, the left and right eye images are always displayed at the time of imaging. can be recorded accurately.

Also, since there is no need to use a viewer, recording paper (
You can easily observe it anywhere as long as you have some film (film) and tinted glasses.
