DETAILED DESCRIPTION OF THE INVENTION

[0001]

[Industrial applications] Lenticular sheets (hereinafter referred to as L
L) formed by applying a photosensitive agent to the back surface of
Among 3D stereographs using a photosensitive sheet with S, there is a method generally called "indirect method". The present invention relates to an apparatus for printing and developing such 3D stereoscopic photographs and ordinary photographs.

[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 printing and developing apparatus for normal photographs.

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

Usually, printing is completed by exposure from a certain direction. 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 lens is required. Also, 3D
Monitor negative images with a TV camera when printing photos
Can be burned efficiently by using
Incorporating it can result in a complex lens mechanism, usually printing photos.
This is a factor that reduces efficiency at the time of installation.

An object of the present invention is to provide an automatic printing and developing apparatus and a minilab system which can efficiently cope with processing of both 3D stereoscopic photography and normal photography.

[0020]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a 2D lens having a fixed 2D lens for photographic printing is usually used.

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. 3
At the time of printing a 3D photograph, the angle of the exposure light beam required 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 exposure table and lens do not move and operate in a state fixed to the paper transport path.

After the completion of the exposure, the paper is transported again by the exposure table 1 for the 3D stereoscopic photograph and the normal photograph again, and sent to the paper processor 11 via the exit roller 5. Conveyed by rollers in the paper processor
The processed print comes out from the drying section outlet 2.

FIG. 2 shows another example of the structure of the minilab system of the present invention. Reference numerals in the figure are 1-exposure table, 2-drying unit, 3-drive roller, 6-paper roll, 11-paper processor, 14-drive motor, 15-supply roller, 17-first cutter, 21- The enlargement lens, 27-cutter section, 31-negative mask, and 39-loop section. The paper drawn by the paper roll 6 reaches the drive roller 3 via the supply roller 15 and the exposure table 1. Printing is performed on the exposure table 1. When printing a 3D stereoscopic photograph, the negative mask 31 and the enlargement lens 21 are moved in the direction of the arrow in the drawing to obtain the angle of the exposure light beam required for printing the 3D stereoscopic photograph.

Reference numeral 14 denotes a drive motor for moving the negative mask 31 and the enlargement lens 21. Usually, this movement is not performed at the time of printing a photograph, and the negative mask and the lens are both fixed on the optical axis and used. It is conceivable that the lens is moved by a feed screw, a feed belt, a rack and pinion, an operation arm, or the like using a drive motor.

After exposure, the roller is conveyed by the driving roller 3 for both 3D stereoscopic photograph and normal photograph, and is sent to the paper processor 11 through the loop portion 39. Paper processor 1
When the length of the series of paper fed into 1 reaches a predetermined amount or when the operator finishes the series of printing operations, the first cutter 17 operates to cut the paper. The paper sent to the paper processor 11 and processed in this way passes through the drying unit 2 and is cut into a print length by the cutter unit 27, and the processing is completed.
