DETAILED DESCRIPTION OF THE INVENTION

[0001]

[Industrial applications] Lenticular sheets (hereinafter referred to as L
A method that is commonly referred to as "indirect method" of 3D stereoscopic photographs using a LS with the photosensitive sheet formed by applying a photosensitive Emulsion on the back surface of abbreviated as S). The present invention can process both such 3D stereoscopic pictures and ordinary pictures.
The present invention relates to a printing / developing device which is also used as a printer.

[0002]

2. Description of the Related Art A general "indirect method" in 3D stereoscopic photography using LS will be described.

For a subject having a depth, a camera containing a normal photosensitive film is moved in the horizontal direction by a predetermined distance, and a plurality of negatives are created for the same subject. These negatives have different image positions depending on the distance between the camera and the subject.

[0004] In addition to the method of taking a picture by moving the camera linearly horizontally, there is also a method of taking a picture by moving the camera in an arc shape with respect to the subject. In any case, it is necessary to obtain a plurality of images from different viewpoints.

[0005] Instead of moving the camera to take a picture, a negative may be obtained by taking pictures at the same time by arranging a plurality of lenses horizontally or by arranging a plurality of cameras horizontally. The number of negatives is not particularly determined, but is 3-5
Is common.

[0006] In the "indirect method", a plurality of negatives obtained in the above process are applied to a photosensitive film with LS, in which a photosensitive material is applied to the flat surface of the LS, by changing the projection angle for each negative. Expose.

When an image is formed on a photosensitive sheet with LS using a normal projection lens, the image is compressed in the horizontal direction by the lenticular lens. Therefore, the projected image is separated by a line separated for each lenticular lens. An image is formed on the photosensitive layer on the back of the lenticular lens as an image.

Then, using the negatives in the following order, the relative positions of the projection lens and the LS-equipped photosensitive sheet are changed so that a new line image is formed next to the line image formed by the previous projection exposure. Perform exposure. In this manner, the width of the back surface of the lenticular lens is successively filled with line images from another negative. Thus, a plurality of negative images can be printed on one photosensitive sheet. This exposure can be performed at a time by a number of projection lenses.

When the thus-prepared print with LS is developed and viewed from the lenticular lens side, the line image formed on the photosensitive layer is enlarged again in the lateral direction by the lenticular lens, and appears as a restored image. In addition, different images sequentially photographed arrive to the right and left eyes, and two pieces of image information are synthesized in the brain of the observer, so that the image can be viewed three-dimensionally.

[0010] How far from the photograph the stereoscopic vision can be improved by viewing the image depends on the conditions when a plurality of images are printed on the LS photosensitive sheet. In general,
In many cases, good stereoscopic vision can be obtained when viewed at a distance about the distance between the projection lens and the LS photosensitive sheet at the time of printing.

As described above, since the exposure process, the photosensitive paper used, and the development process at the time of printing differ greatly from those of a normal photograph, a 3D stereoscopic photograph is processed using a special printing / developing apparatus separate from the normal photograph. Have been. In some cases, it is performed manually.

Normally, in the printing and developing process of a photograph, a means for transporting a negative and a photographic paper and a fixed lens and an exposure table, a developing,
A baking developing device provided with a means for drying is used.
In the usual photographic process, as a result of the need to speed up the printing process while maintaining or improving the image quality, photographic paper with high sensitivity and a thin emulsion has been used.
The time required for exposure, development and drying has been reduced.

[0013] The baking developing device also shortens the processing time, and there are various developing devices ranging from large devices used in factories to small devices used in retail stores and the like. On the other hand, the orientation has been diversified, such as special-size photographs, such as those found in panoramic photographs, and various forms have emerged in ordinary photographs, and various sizes have also been accommodated in print development processing. Have been.

[0014]

[0006] In addition to the exposure method, the resolution and sensitivity of the photosensitive paper, the composition and material of the substrate, emulsion, and the like, besides the exposure method, differ greatly between the normal photograph and the 3D stereophotograph. When considering a photographic processing system, it must be appropriate for the characteristics of the photosensitive material. For this reason, a 3D stereoscopic photograph cannot be processed using a normal photographic printing and developing apparatus.

In this case, it is sufficient to perform the processing with a special printing / developing apparatus. However, the spread of 3D stereographs is limited, and it is difficult to collect a large number of processed images. In particular, when processing is performed at a retail store, it is difficult to maintain the processing device due to problems such as liquid management and profitability. These reasons further hinder the spread of 3D stereoscopic photography.

If a 3D stereoscopic photograph can be processed using a printing / developing apparatus for processing a normal photograph, over-the-counter processing is also possible. However, as described above, it is not easy because the characteristics of a normal photograph and a 3D stereoscopic photograph are greatly different.

If the conventional techniques are simply put together to form an apparatus that can share or use the printing and developing of a normal photograph and a 3D stereoscopic photograph, various problems occur. For example, in the case of 3D stereography, the exposure means is complicated and the development process requires time, so that the performance of a printing and developing device for normal photography is reduced, and sufficient performance is obtained for both 3D stereography and normal photography. It is difficult to provide a processing system having

The problem in enabling processing of both a 3D stereoscopic photograph and a normal photograph by one system will be described more specifically.

(1) Normally, printing is completed by exposure from a certain direction in a normal photograph. However, in the case of a 3D stereoscopic photograph, at least 3 to 5 or more exposures are required by changing the angle of a light beam. A moving mechanism such as a photosensitive paper and a lens is required.

(2) Normally, photographic printing paper is exposed on the emulsion surface. However, 3D stereoscopic photography is performed by using photosensitive paper having a surface on which a number of small lenticular lenses are arranged, and exposing from the lenticular lens side. The emulsion side is reversed between the normal photograph and the 3D stereoscopic photograph.

(4) There is a large difference in the characteristics of the photosensitive paper between a normal photograph and a 3D stereoscopic photograph, and the time required for development, bleach-fixing, stabilization, and drying is different.

When trying to solve the above-mentioned problems, there may be problems arising therefrom. SUMMARY OF THE INVENTION An object of the present invention is to provide an automatic printing / developing apparatus and a minilab system which can handle both 3D stereoscopic photography and normal photography.

[0023]

In order to solve the above-mentioned problems, an apparatus according to the present invention comprises a lenticular sheet and a photosensitive emulsion.

The device is provided with at least means.

The apparatus of the present invention has a function of processing a 3D stereoscopic photograph in addition to the function of a conventional minilab for processing a normal photograph.
Photosensitive paper can be processed. In a 3D stereoscopic photograph, as in the case of a normal photograph, the transfer of the photographic paper from printing to development is all performed automatically, and the operator need only perform the operation of selecting the main subject of the 3D stereoscopic photograph.

[0027] For minilab system of the present invention, the
An example will be described with reference to the drawings. FIG. 1 is a drawing showing an example of the structure of the minilab system of the present invention. Symbols in the figure are 1-exposure table, 2-drying section (exit), 3-drive roller,
4-slide motor, 5-exit roller, 6-paper roll, 7-cutter, 8-slide screw, 11-paper processor, 18-slide shaft, 21-extension lens.

The operation of the illustrated device is as follows. The paper drawn by the driving roller 3 by the paper roll 6 is cut into a predetermined length by a cutter 7. The cut paper is conveyed to the exposure position while being attracted to the exposure table 1. The exposure table 1 is supported by a slide shaft 18 and is moved by a slide motor 4 and a slide screw 8 in a direction perpendicular to the paper transport direction.
At the time of printing a 3D stereoscopic photograph, the angle of the exposure light beam necessary for printing can be obtained by this movement. In conjunction with this operation, the stretching lens 21 also moves and follows the movement of the exposure table 1. On the other hand, when performing normal printing,
The lens does not move and operates while being fixed to the paper transport path.

After the completion of the exposure, the paper is transported again by the exposure table 1 and sent to the paper processor 11 via the exit roller 5 in both the 3D stereoscopic photograph and the normal photograph. At this time, a device for reversing the paper is interposed before the paper is transported from the exposure table 1 to the paper processor.
When developing a 3D stereophotograph, the paper is turned over to make the emulsion surface coincide with the normal photo. By making the direction of the emulsion surface constant during development processing, it is possible to cope with various types of paper. In the paper processor, the print is conveyed and processed by rollers, and the finished print comes out from the drying section outlet 2.

FIG. 2 shows the structure of the suction type exposure table used in the above example. Reference numerals in the figure are 9-suction plate, 12-suction box, 16-belt, 19-driven pulley, 22-suction fan, 24-convey motor, 29-drive pulley, 3
2- duct. The structure of the exposure table is a drive pulley 29,
A large number of small holes are provided in the wide belt 16 stretched between the driven pulleys 19, and the paper is sucked by the suction force generated by the suction fan 22 through the small holes.
The suction plate 9 secures the flatness of the exposed portion of the belt 16, and the suction box 12 distributes the suction force of the fan over the entire exposure table. 3
Reference numeral 2 denotes a duct connecting the two.

After the paper is cut to a predetermined length by a cutter, the paper is attracted to the belt and transported to an exposure position by driving a transport motor. Once the exposure is over,
The transport motor rotates again and sends the paper to the exit roller. It is necessary to change the attraction force of the exposure table according to the thickness of the photographic paper. Means for changing the suction force include changing the supply voltage to the suction fan that provides the suction force, changing the flow rate of air, and the like.

FIGS. 3A to 3D are diagrams schematically showing an example of paper transport. The symbols in the figure are those in FIGS.
Similarly, 1-exposure table, 3-drive roller, 5-exit roller, 6-paper roll, 7-cutter, 16-belt, 18-slide shaft. First, (1) the leading end of the paper is waiting at the cutter unit 7. (2) When the drive roller 3 rotates and the paper is fed by a predetermined length, the cutter 7 operates to cut the paper. Then belt 1
The wafer is transported to the exposure position while being sucked by the motor 6, and then stopped.
(3) At this position, exposure is performed while the entire exposure table 1 moves along the slide shaft 18. (4) After the exposure is completed, the sheet is conveyed again to the exit roller 5 by the belt 16. With the above-described mechanism, an automatic printing and developing apparatus capable of coping with printing and developing processing of both normal and 3D stereoscopic photographs can be obtained.
