[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for producing a three-dimensional photograph using a lenticular screen.

[0002]

2. Description of the Related Art Conventionally, a method for producing a three-dimensional photograph using a lenticular screen has been known.

According to a conventional known manufacturing method, first, an object such as a landscape or a person is photographed a plurality of times while moving the camera in the horizontal direction by a predetermined distance, whereby a series of a plurality of sheets is taken. Make a negative. Next, on a printing material for stereoscopic photography with a lenticular screen attached on the surface, a series of negatives described above is formed so that a belt-shaped image compressed by the lenses is continuously formed below each lens of the lenticular screen. , And the exposure is performed by changing the position of each negative and the printing material in the parallel direction by a constant distance. Then, the light-sensitive material is developed to obtain a three-dimensional photograph.

However, in the above-mentioned conventional manufacturing method,
Since it is difficult for a person to be completely still when taking a picture of a subject, the person moves during the plurality of times of shooting. In addition to the animals and cars in the landscape, the flowers, trees, etc. also move due to the wind. Therefore, there is a problem that the obtained three-dimensional photograph becomes unclear.

In order to solve this problem, it has been proposed to use a special camera in which a plurality of cameras are linearly arranged and a plurality of negatives are photographed by one photographing.

However, since this special camera cannot change the pitch between the cameras, the stereoscopic effect disappears or becomes unnatural when the distance to the object deviates from a predetermined range.

Further, in the above-described conventional manufacturing method, since it is necessary to take a picture for a stereoscopic picture in a place where a subject desired to be a stereoscopic picture exists, it takes a lot of time and labor for the picture taking. .

The applicant of the present invention has previously proposed a method for solving the above-mentioned problems as Japanese Patent Laid-Open No. 2-293733.

FIG. 3 shows images PI1 to PI8 of the material image group GP.
FIG. In FIG. 3, as the material image group GP, five single images PI1 to 4, 8 and one stereoscopic image group GT1 including three stereoscopic images PI5 to 7 are shown. The stereoscopic images PI5 to PI7 are images of a building, which is an object (subject), taken from three different horizontal positions. These images PI1 to
8 is embodied as, for example, a photographic film, a photograph printed on photographic paper, or the like.

Each of the images PI1 to PI of these material image groups GP

It is stored in.

Next, a two-dimensional image of a three-dimensional photograph to be produced is produced. FIG. 4 is a diagram showing an example of a composite image PS1 which is the basis of a stereoscopic photograph. In FIG. 4, the composite image PS1 is
The images PI1 to 5 in the material image group GP are arranged and configured. In the composite image PS1, the background image PI1 serves as a reference for the moving distance. The image PI3, the image PI2, and the image PI4 are separated from the image PI1 by distances L1, L2, and L3, respectively. The image PI2 and the image PI5 are separated by a distance L4.

Such a composite image PS1 can be displayed by looking at the screen HG of the display device 15 and designating with the keyboard 17 or the mouse 18 to obtain the material image group G.
It is produced by sequentially selecting the images PI1 to P5 from P and arranging them at predetermined positions. The created composite image PS1 is stored in the main memory or the frame memory MF of the processing device 11.

Then, the composite image PS1 is transferred to the frame memories MF11-14. Frame memory MF11
The same image data as that of the composite image PS1 is written in to. Unnecessary image PIs are erased from the frame memories MF11 to 14, and only the necessary image PIs are left.
As a result, the frame images PF11 to 14 in which the images PI corresponding to the perspective positions are written are created on the frame memories MF11 to 14.

7 to 10 are frame images P respectively.
FIG. 11 is a diagram showing an example of F11 to F14, and FIG.
It is a figure which shows the relationship between F and the composite image PS. The frame image PF11 shown in FIG. 7 includes the composite image PS1 to the image PI.
1, 2, 4, 5 are erased and only the image PI3 is left. The frame image PF12 shown in FIG. 8 is obtained by deleting the images PI1, 3, 4 from the composite image PS1 to obtain the image PI2.
Only 5 is left. The frame image P shown in FIG.
F13 is the composite image PS1 to images PI1, 2, 3, 5
Is deleted and only the image PI4 is left. Figure 10
The frame image PF14 shown in (1) is one in which the images PI2, 3, 4, and 5 are deleted from the composite image PS1 and only the image PI1 remains.

That is, these frame images PF11 to 1
When 4 is combined, a combined image PS1 is obtained. In producing each of the frame images PF11 to 14, the image PI desired to have the same perspective position is assigned to each of the same frame memories MF11 to MF1.
Leave on 4. In this example, the image PI2 and the image PI5 are left in the frame memory MF12. Further, the image PI for which the perspective position is desired to be closer is left in the order of the frame memory MF11, the frame memory MF12, the frame memory MF13, ....
Therefore, the image PIs having the same perspective positions are left in the frame memories MF11 to 14,
The frame image PF11 becomes the closest position, and the frame image PF12, the frame image PF13, and the frame image P
It becomes distant in the order of F14.

Next, a composite image PS2 is produced. FIG. 5 is a diagram showing an example of the composite image PS2. Composite image PS2
In the production of, each frame image PF11 ~ 13,
The distances a, b, and c are moved in the same lateral direction (to the right). The movement distances a, b, and c of the frame images PF11 to 13 are the frame images P having the closest perspective positions.
F11 is the largest, and becomes smaller in the order of the frame image PF12 and the frame image PF13. Therefore, a>b> c. The frame image PF14 is not moved.

The moved frame images PF11 to 13 and the frame image PF14 are stored in the frame memories MF21 to MF2.
No. 4 and the frame images PF21 to PF24. Since the frame image PF14 is not moved, the content of the frame image PF24 is at the same position as the content of the frame image PF14. Then, regarding the stereoscopic image PI5 selected from the stereoscopic image group GT1, the stereoscopic image P
I5 is replaced at the same position as the stereoscopic image PI6. Therefore, the frame image PF22 is the frame image PF1.
The position 2 is moved, and the image PI5 is replaced with the image PI6. When these frame images PF21 to 24 are combined, a combined image PS2 is obtained. The composite image PS2 can be displayed on the screen HG, and can be printed by the printer device 16.

Next, a composite image PS3 is produced. FIG. 5 is a diagram showing an example of the composite image PS3. Composite image PS3
In the production of, each frame image PF11 ~ 13,
The distances 2a and 2 are twice as large as those of the composite image PS2, respectively.
Only b and 2c are moved in the same horizontal direction (to the right). The frame image PF14 is not moved.

The moved frame images PF11 to PF14
Is transferred to the frame memories MF31 to 34 to form frame images PF31 to 34. Then, the stereoscopic image group GT
For the stereoscopic image PI5 selected from 1, the stereoscopic image PI5 is replaced at the same position as the stereoscopic image PI7. Therefore, in the frame image PF32, the position of the frame image PF12 is moved, and the image PI5 is replaced with the image PI7. When these frame images PF31 to 34 are combined, a combined image PS3 is obtained. The composite image PS3 can be displayed on the screen HG and can be printed by the printer device 16.

Now, as described above, the frame image PF
11-14, PF21-24, and PF31-34 are produced, and based on them, the composite images PS1-3 are printed on the film by the printer device 16. For the composite images PS1 to PS3 on the film, either a negative image or a positive image can be selected.

Using a series of printed films of the composite images PS1 to PS3, a photographic film for stereoscopic photography having a lenticular screen is exposed and the image is printed to produce a stereoscopic photograph. As a method for printing an image, various known methods such as those disclosed in JP-A-2-293733 can be used.

In the printing, the composite images PS1 to PS1
Since the key image PI2 was moved during the production of No. 3, when it was exposed to the printing film, it was moved in the opposite direction on the printing film by an amount corresponding to the moving distance of the image PI2. By doing so, the image PI2 of the key is fixed and appears clearly in the three-dimensional photograph.

According to the above-described embodiment, the single images PI1 to PI4 and the stereoscopic image group GT1 are included in the material image group GP.
And a plurality of stereoscopic images PI5 to 7 that form
In producing the composite images PS1 to PS3, the material image group GP
Since at least one stereoscopic image group GT1 is selected from among the selected stereoscopic image groups GT1 and different images PI5 to 7 in the selected stereoscopic image group GT1 are arranged in each of the composite images PS1 to PS3, the type of the object Irrespective of the above, a three-dimensional photograph can be produced from a two-dimensional image, and in the case of using the three-dimensional images PI5 to 7, a stereoscopic effect can be obtained by itself, and a more natural three-dimensional photograph is produced. be able to.

Therefore, even if an object is likely to move, such as a person or an animal, a clear three-dimensional photograph is created based on a single photograph taken in a stationary state without using a special camera. can do. You can create a stereoscopic photo based on a normal photo or illustration, even if it is not a special photo taken for stereoscopic photography, so you can use any image at hand and make a stereoscopic photo. The time and cost required for this is greatly reduced. Also, three-dimensional photographs can be used for things that existed in the past but no longer exist today, fictitious ones, antique paintings, and the like.

As described above, various images are displayed as the material image group GP.
, Or by reading it with the image scanner 12 and constructing a database of the image data DP, an image is selected from a wide range and each selected image is arranged at an arbitrary position in the perspective position. It is possible to make a three-dimensional photograph.

In general, a distant image at a perspective position in a stereoscopic photograph tends to be flat, but according to the above-described embodiment, the stereoscopic image PIt is photographed so that an appropriate stereoscopic effect can be obtained. Even if it is arranged at a distant position, a sufficient three-dimensional effect can be obtained.

In the above embodiment, the stereoscopic image group G is used.
Although T1 is arranged in the same frame memory MF12, 22, 32 as the key image PI2, it may be arranged in another frame memory MF. Although only one stereoscopic image group GT1 is selected, a plurality of stereoscopic image groups GT may be selected. In that case, the stereoscopic images PIt may be arranged in the same frame memory MF or may be arranged in different frame memories MF. One stereoscopic image PI5 to 7 in the stereoscopic image group GT1 may be used in the same manner as the normal single image PI1 to 4 instead of being used as the stereoscopic image.

In the above-described embodiment, four frame memories MF are used to produce one composite image PS, but three or less or five or more may be used. Although three synthetic images PS1 to 3 are produced, two or four or more synthetic images PS may be produced. Frame images PF11-
Although the unnecessary image PI is deleted from the composite image PS1 in manufacturing the image 14, the necessary images PI1 to 8 may be arranged in the frame memories MF11 to 14. Frame image PF1 in which frame images PF31 to PF31 are first created
1 to 14, but may be created from the frame images PF21 to 24 that were created one before. Frame image P
In producing F21 to 24 and PF31 to 34, the frame image PF14 in which the background image PI1 is written is fixed without moving, but the frame image PF12 in which the key image PI2 is written may be fixed. In that case, when printing a three-dimensional photograph, the key image PI
2 may be fixed.

In the above embodiment, the composite image PS1
3 to obtain three types of frame images PF11 to 1
4, PF21 to 24, PF31 to 34 were produced,
One type of frame image P corresponding to one composite image PS1
Only F11 to 14 are produced, and for the other composite images PS2 and PS3, the moving distance or relative position with respect to the frame images PF11 to 14 is stored in the memory, and the composite images PS2 and PS3 are displayed or printed. At times, the frame images PF11 to 14 may be moved by the distance stored in the memory. By doing so, the memory capacity of the frame memory MF is reduced.
The frame memory MF may be any memory that can store the image data DP and can specify its position.

In the above embodiment, the image data DP read by the image scanner 12 is compressed,
Stretch, modify, move, rotate, flip, mirror, color convert,
Various processes such as edge enhancement and blurring may be performed.
In addition, the three composite images PS1 to PS3 stored in the memory
From the above, an image for a lenticular screen type three-dimensional photograph may be prepared by calculation, and the image may be printed on a photographic printing film or printing paper.

In the above-described embodiment, the composite image PS is produced by the producing apparatus 1 using a computer.
Instead of using the manufacturing apparatus 1, a composite image PS may be manufactured by cutting and sticking a film or paper or taking a photograph. In addition, the configuration of each part or the whole of the manufacturing apparatus 1, the processing content, the order, and the like can be appropriately changed in accordance with the gist of the present invention.
