Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an integral photography [IP] in a three-dimensional image technology, and more particularly to a method for producing an IP from a motion picture film and a fly's eye lens plate and the IP.

[0002]

2. Description of the Related Art Conventionally, in three-dimensional image technology, I
ntegral Photography [hereinafter abbreviated as IP] is well known. This will be explained. First, a fly-eye lens plate is used. This is a lens plate consisting of many small convex lens groups. A photographic plate is placed behind the lens plate on the focal side. The light from the subject is exposed from the front of the lens plate to take a picture. Images of a large number of subjects viewed from different directions corresponding to the respective lens positions are recorded on the dry plate. This is developed and put in the same position as the front behind the lens plate. Illuminate this and look from the front. Due to the illumination, the light of the images of many subjects seen from different directions from the focal side,
It is added by the refraction of the corresponding lens,
Reproduce a three-dimensional image of the subject in front of the lens plate. You can see this.

By the way, the reproduced image is composed of an inverted image obtained by photographing a subject with a large number of convex lenses. The reproduced image of the subject viewed from the front of the lens plate is left, right, front and back (concave and convex) with respect to the lens plate. Is the opposite.

In such an apparatus, for example, the inverted image is photographed again on the front side of the IP, and the erect images obtained by photographing the inverted images with the convex lenses are added together. ) Can be not the opposite.

[0005]

However, in the conventional IP creating method, regardless of the former and the latter, images of a large number of objects viewed from different directions are once captured by a fly-eye lens plate on one dry plate. It is to shoot and record.

Therefore, in the above-described IP creating method, the shooting is special because the fly's-eye lens plate and the dry plate are prepared for each shooting, and the IP can be easily created. There is a problem that it is difficult.

Therefore, according to the present invention, an image of a large number of subjects viewed from different directions is photographed and recorded on another film by a general method, and the images are divided and arranged to easily create an IP. The purpose is to obtain.

[0008]

Means for Solving the Problems In order to achieve the above object, the solution means taken by the present invention is an integral po that records and reproduces images of a large number of subjects viewed from different directions.
The fly-eye lens plate for reproducing a three-dimensional image is provided in advance, and the fly-eye lens plate uses a large number of convex lenses or Fresnel lenses thereof for one movie film. 1 at intervals
While arranging them in a row and forming them by arranging them in a plurality of rows with the film width, by providing a photographing point corresponding to each lens position and sequentially moving the photographing points, images of many subjects viewed from different directions can be obtained. , Using a camera, send the movie film to the exposure surface formed at the focal point on the optical axis through the objective lens consisting of the convex lens, and sequentially shoot and record one frame at a time. In that case, Is photographed and recorded so that the direction in which the motion picture film is fed to the exposure surface and the moving direction of the above-mentioned photographing point are parallel, and this is developed, and the photographed ones are divided for each row, Are arranged on the focal side corresponding to each lens position behind the fly-eye lens plate to create an IP and the IP.

[0009]

With the above-described structure, in the present invention, by sequentially moving the photographing points, images of a large number of subjects viewed from different directions are sequentially photographed one by one on the movie film by using the photographing device.

In this case, since the film is photographed so that the direction in which the film is fed to the exposure surface of the photographing device and the moving direction of the photographing point are parallel to each other, the photographing device passes through the objective lens consisting of a convex lens on the exposure surface of the film. To record an inverted image,
For example, when the film is taken on the exposed surface and the moving direction of the shooting point is different from each other, the images are taken, developed, and divided and arranged, the inverted images are lined up as a whole.
The same thing as the former one mentioned in P is obtained.

Further, when the images are taken in the same direction, developed, and divided and arranged side by side, the erect images are arranged on one surface by reversing the direction by 180 degrees and arranging them one by one. The same thing as the latter mentioned in the conventional IP can be obtained.

Then, the elements arranged in the focal side corresponding to the respective lens positions behind the fly-eye lens plate are illuminated. The lights of the images of a large number of objects seen from different directions from the focal side are added together by refraction of the corresponding lenses, and a three-dimensional image of the object is reproduced in front of the fly-eye lens plate. You can see this.

Embodiments of the present invention will be described below in detail with reference to the drawings. First, FIG. 1 illustrates an example of an image capturing operation according to the present invention. M is a photographing device, L is a subject (model of a yacht), and a large number of images of the subject L viewed from different directions are photographed using the photographing device M. This is photographed and recorded on a movie film, here, a movie 8 mm film 1 as shown in FIG.

On the other hand, as shown in FIG. 8, a fly-eye lens plate 2 for reproducing a three-dimensional image is provided in advance.
The fly-eye lens plate 2 has a large number of convex lenses 3 arranged in a horizontal row in the left and right at intervals s (about 4 mm) of one frame of the film.
In addition to arranging them individually, a plurality of them are formed with a film width g (about 8 mm) and m rows are formed vertically. Here, m and n are natural numbers, and in this embodiment, for example, m = 18 and n = 1.
8 is used. Then, the front side of the convex lens surface c
Then, the rear focal side is formed by a flat focal plane e including the focal point behind each convex lens 3.

In this embodiment, the fly's eye lens plate 2 is used.
Is formed by a large number of convex lenses 3, or the optical surface of each convex lens 3 is, for example, as shown in FIG.
A transparent sheet 6 is formed on the lens sheet 5 formed by the Fresnel lens 4.
It may be formed by providing the focal plane d on the rear side of the focal plane.

On the other hand, in the photographing according to the present invention, as shown in FIG. 1, photographing points a _ij (i = 1, 2, 3, ... _M , corresponding to each lens position of the fly-eye lens plate 2). j = 1,
2, 3, ... N) are arranged in a grid and photographed. However, a _ij is a matrix display, and in the same figure, means a shooting point corresponding to the center position of the j-th convex lens 3 in the i-th column from the top. Then, for example, with respect to i = 1, the j from j = 1 is changed from j = n, the imaging point _{a lj,} until _{a 11 or} al _{a ln} accordance with the direction of movement x (rightward in the drawing), sequentially moved And shoot. Similarly, for i = 2, i = 3 ... i = n, j is similarly changed and the photographing points a _ij are similarly sequentially moved and photographed in accordance with the movement direction x. In that case, it is assumed that the row to be photographed sequentially moves in accordance with the movement direction y (from top to bottom in the figure) as i changes. By doing so, a large number of images of the subject L viewed from different directions can be photographed by scanning with the photographing device M.

Next, the structure of the camera M will be described with reference to FIG. G is an objective lens composed of a convex lens, and 7 is a shutter blade. The shutter blade 7 is formed of a circular plate having an arcuate opening 7a, which rotates through a shutter shaft 8 and is exposed when the opening 7a comes in front of the film 1. Minutes are filmed. When one frame has been taken, the disk rotates and blocks the light,
The film 1 is fed by the feeding pawl 9 and the frame 10 formed on the side of the film is hooked and fed by one frame, and this operation is repeated. Then, the film 1 is sent through the objective lens G composed of the convex lens to the exposure surface 11 formed at the focal point on the optical axis h thereof, and one frame at a time, and a large number of subjects L viewed from different directions. An image is formed on the exposed surface 11 and photographed and recorded on the film 1.

In that case, in particular, in the present invention, in the present invention, as shown in FIGS. 1 and 2, the shooting point a _ij passes through the optical axis h, and the direction f in which the film 1 is sent to the exposure surface 11, The image is taken and recorded so that the moving direction x of the shooting point a _ij is parallel. As a result, it is possible to record images of a large number of subjects L photographed at the photographing points a _ij on the film 1 as corresponding to the respective lens positions of the fly-eye lens plate 2.

The developed product is illustrated in FIG. a ₁₁ ... a _ij ... a _mn are images recorded corresponding to the respective shooting points a ₁₁ ... a _ij ... a _mn , respectively. Here, since each image a _ij is imaged through the objective lens G formed of a convex lens, each image a _ij is
It is recorded as an inverted image.

The image thus developed is transferred to each column (i
= 1,2,3, ...

At this time, in the present embodiment, in order to simplify this division, as shown in FIG. 1, in addition to the photographing point a _ij at the time of photographing, the photographing point b _ik (k = 1, 2, 3,). ... t) is provided. However, b _ik is a matrix expression like a _ij , t is a natural number, and in the present embodiment, for example, up to t = 2 is used.

Then, when the same i-th row is photographed, either before or after the row of the photographing points a _ij , in the present embodiment, 2 after that.
Each frame in advance (i = 1, 2, 3, ...)
After development, the images photographed for each m) are photographed and recorded on the film 1 so that the image of the plate N as a mark is photographed so that they can be easily and separately divided. This means, for example, at the time of shooting, at the shooting point b _ik , touch the mark plate N with the hand R
Then, as shown by an arrow z, the object is photographed and recorded by holding it in front of the objective lens G.

A developed version of this is likewise illustrated in FIG. The image b _ik is an image recorded corresponding to each shooting point b _ik , like the image a _ij . By doing so, an image b _ik recorded as a shadow of the plate N, which is different from the image a _{ij of the} subject L and is recorded on a part of the film 1, for each two frames, for each row. They are recorded so that they are separated from each other, so that it is possible to distinguish on the film what was taken in each row.

When this is divided, as shown in the same figure, with the image b _ik portion on the film 1 as a mark, the arrow p
By cutting with scissors or the like, it is possible to easily divide the captured images into each row. FIG. 5 illustrates an example in which it is divided and arranged. Incidentally, the image b ₀₂ shows a photographed image recorded at the beginning of the film in the same manner as the image b _ik .

Then, as shown in FIGS. 6 and 7, one frame is made to correspond to each lens position of the fly-eye lens plate 2 to form a flat focal plane e including the focal point behind the fly-eye lens plate 2. By arranging them, IPα can be created.

Therefore, in the embodiment, for example, as shown in FIG. 1, the photographing point a _ij is moved in the moving direction x and the moving direction y.
By sequentially moving the images a _ij of a large number of subjects L viewed from different directions by using the photographing device M.
Shoot and record one frame at a time on m-film 1.

In this case, as shown in FIG. 2, since the direction f of feeding the film 1 to the exposure surface 11 of the photographing device M and the moving direction x of the photographing point a _ij are parallel, the photographing is performed. The machine M records the inverted image one frame at a time on the exposed surface 11 through the objective lens G formed of a convex lens on the film 1.

At this time, for example, in the case where the film 1 is sent to the exposure surface 11 in a different direction from the moving direction x of the shooting point a _ij , the images are taken, developed, and divided and arranged side by side. As described in the operation, it is possible to obtain the same thing as the former one in the conventional IP in which the inverted images are lined up as a whole.

In the present embodiment, the direction f and the moving direction x are set to the same direction, and the images are taken, and when the images are developed and divided and arranged side by side, the direction is changed by 18 for each line.
Since they are arranged 0 degrees opposite to each other, it is possible to obtain the same one as the latter in the conventional IP in which the erect images are arranged on one side as a whole.

The film 1 thus photographed and recorded
3 is illustrated in FIG. On the film 1, the upright image a _ij of the model of the yacht of the subject L, taken from different directions frame by frame, is the fly-eye lens plate 2
Are recorded so as to correspond to the respective lens positions.

That is, in the present embodiment, the hole 10 on the side of the film is actually set to the lower side, for example, the left side in FIG.
Because were recorded image a _ij be inverted frame by frame, those that developed, by arranging to the vertical and horizontal in the opposite 180 degrees, as shown in FIG. 3, on the film 2, upright image a _ij However, the holes 10 on the side of the film are arranged side by side, that is, an erect image can be obtained.

Further, in the present embodiment, at the time of photographing, after each row of the photographing points a _ij , the image b _ik of the plate N as a mark of two frames photographed is _divided on the same film 3 for each row. Since the image was taken and recorded as described above, by cutting at the image b _ik at this mark, the image taken and recorded for each column can be easily distinguished and divided on the film 1.

Then, by simply dividing these and arranging them on the focal side corresponding to each lens position behind the fly-eye lens plate 2 as shown in FIGS. 6 and 7, the IPα can be easily created. You can

Next, as shown in FIGS. 6 and 7, illumination light (arrow w) is applied to IPα. Then, for example, lights (arrows u and v) of the adjacent images A and B of a large number of subjects L viewed from different directions from the focal side are added together by refraction of the corresponding lenses 3, respectively, and the line of sight ( With respect to the arrow r), the three-dimensional image J of the subject L is reproduced in front of the fly-eye lens plate 2. You can see this.

As described above, according to this embodiment, the photographing device M
Direction f of feeding the film 1 to the exposure surface 11 of the
The moving direction x of _ij is made parallel to each other, and the frames are sequentially photographed and recorded on the film 1, the film 1 is developed, and the photographed images are divided for each row. Arrange on the focal side corresponding to each lens position in the rear,
Since the special shooting such as the fly's eye lens plate and the dry plate as in the past can be made into the general one of the shooting machine and the movie film, the IP can be easily created compared to the conventional one. be able to.

In this embodiment, the 8 mm film for movie 1 is used as the movie film, but the film is not limited to this, and various other similar films may be used.

Further, in this embodiment, the hole 10 on the side of the film is used.
Although the film width g including the film width is used as the film width, only the portion where the image is recorded may be used as the film width excluding the film side portion.

Further, in this embodiment, the image b _ik of the plate N as a mark, and the images recorded and photographed in each row are photographed and recorded so that they can be distinguished on the film 1 after development. However, the image b _ik is not limited to this, or as a method for distinguishing it, an image having an audio magnetic tape on the film side is used, and an audio signal is recorded as a mark at the photographing point b _ik . You may

In addition, in the present embodiment, images of the subject L viewed from different directions are photographed and recorded directly on the film 1 by using the photographing device M, but in addition, indirectly, for example, a still video camera photographing device. The image of the subject L at each shooting point a _ij may be once recorded on another medium and reproduced on a monitor or the like, and may be shot and recorded by the shooting device M. The image of the subject L in a _ij can be displayed by computer graphics (CG), etc.
A virtually created screen may be reproduced, photographed and recorded. In that case, in the shooting, the image reproduced corresponding to each shooting point a _ij and the shooting device M
The image to be reproduced is photographed and recorded so that the image to be reproduced is moved in parallel with the moving direction of each photographing point on the screen and the direction f of the film 1 sent to the exposure surface 11 of the photographing machine M. It goes without saying that you do.

[0040] Moreover, in this way what was recorded image a _ij of the object L at each photographing point a _ij, copied in the form of after arranging the film 1 before the division form or divided and, it flies It goes without saying that an IP may be similarly created by providing the lens on the focal side corresponding to each lens position behind the lens plate.

Further, in this embodiment, the distances between the photographing points a _ij corresponding to the respective lens positions of the fly-eye lens plate 1 are set to be the same as the distance s and the film width g corresponding to one frame of the film. However, the intervals are not limited to the same size, and the subject can be enlarged or reduced by setting reduction or enlargement.

[0042]

As described above, according to the present invention, while the fly-eye lens plate is exclusively used for reproduction, the shooting points corresponding to the respective lens positions of the fly-eye lens plate are moved in sequence to obtain different directions. Using a camera, the images of a large number of subjects viewed from the film were taken one by one on the film for cinema with the direction of feeding the film on the exposed surface parallel to the moving direction of the shooting point. Record, develop the film,
The IPs are created by dissecting the images taken in each row and arranging them on the focal side corresponding to each lens position behind the fly's eye lens plate, so that the fly's eyes like the conventional ones are used. The special photographing of the lens plate and the dry plate can be generalized to the photographing machine and the movie film, and the IP can be created and obtained more easily than in the past.
