Abstract

PURPOSE:To enable the execution of processing of both of an ordinary photograph and a stereoscopic photograph with one unit of mini-laboratory by selecting a movable exposing base, lenses and emulsion surfaces and executing development processing and drying and finishing. CONSTITUTION:A 3D lens 23 and a camera 25 for monitoring negatives are installed on a 3D lens plate 20 which is placed on linear rails 22. A feed screw 28 and the 3D lens plate 20 are fixed by a fixing block 26. A 2D lens 13 is installed onto a 2D lens plate 10 and is used by being fixed in a home position. The 3D lens plate 20 is retreated to an alternate long and short dash line position in Fig. via the feed screw 28 by rotation of a motor 24 at the time of using the 2D lens 13. Printing is executed by moving the 3D lens plate 20 so as to obtain a desired photographing angle at the time of using the 3D lens 23. The differences in the development time are dealt with by switching the transporting routes of the developing section in such a manner so that the adequate development processing is executed regardless of the differences in the processing time.

Description

Detailed Description of the Invention

[0001]

[Industrial application] Lenticular sheet (L
L formed by applying a photosensitizer to the back surface of
Among 3D stereoscopic photographs using a photosensitive sheet with S, there is a method generally called “indirect method”. The present invention relates to a printing and developing apparatus for 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 an ordinary photosensitive film is moved in the horizontal direction by a predetermined distance to make a plurality of negatives for the same subject. These negatives have different image positions depending on the distance from the camera to the subject.

In addition to the method of linearly moving a camera for photographing, there is also a method of moving an object in an arc shape for photographing. In any case, it is necessary to obtain multiple images from different viewpoints.

Instead of moving the camera to take a picture, a camera having a plurality of lenses arranged horizontally or a plurality of cameras arranged horizontally may be taken at the same time to obtain a negative. The number of negatives is not fixed, but 3-5
Is normal.

In the "indirect method", a plurality of negatives obtained in the above-mentioned steps are applied to a photosensitive film with LS in which a photosensitive material is coated on the flat side of LS, and the projection angle is changed for each negative. Expose.

When a negative image is formed on a photosensitive sheet with LS by a normal projection lens, the image is laterally compressed by the lenticular lens, so that the projected image is separated by lines for each lenticular lens. An image is formed on the photosensitive layer on the back surface of the lenticular lens.

After that, by using the negative of the following order, the relative position of the projection lens and the photosensitive sheet with LS is changed so that a new line image is formed next to the line image formed by the previous projection exposure. Expose. In this way, the width of the back surface of the lenticular lens is filled with line images from different negatives one after another. In this way, a plurality of negative images can be printed on one photosensitive sheet. This exposure can also be performed at once with a large number of projection lenses.

When the LS-attached print thus produced 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 captured in sequence to the right eye and the left eye arrive, the two pieces of image information are combined in the observer's brain, and they can be viewed stereoscopically.

How far away from the picture a good stereoscopic vision can be obtained depends on the conditions when a plurality of images are printed on the LS photosensitive sheet. In general,
In many cases, good stereoscopic viewing is possible when viewed at a distance about the distance between the projection lens and the LS photosensitive sheet during printing.

As described above, since the exposure process at the time of printing, the photosensitive paper used, and the development process are greatly different from those of the ordinary photograph, the 3D stereoscopic photograph is processed by using a dedicated baking and developing apparatus different from that of the ordinary photograph. Has been done. It may also be done manually.

[0012] In the usual photographic printing and developing process, a negative, a means for conveying photographic paper, a fixed lens and an exposure base, a developing,
A printing and developing device provided with a means for drying is used.
In the process of normal photography, while maintaining or improving the image quality, it has been required to accelerate the print development process, and as a result, photographic paper with high sensitivity and thin emulsion has come to be used.
The time required for exposure, development and drying has been shortened.

The bake developing device also shortens the processing time, and there are various developing devices ranging from large equipment used in factories to small equipment used in retail stores. On the other hand, the diversification of intentions such as special size photographs such as those seen in panoramic photographs has progressed, and various forms have come to exist in normal photographs as well, and various sizes can be supported in printing and development processing. Came.

[0014]

In addition to the exposure method, the resolution, sensitivity, substrate, emulsion, and other composition / materials, composition, etc. of normal photography and 3D stereoscopic photography differ greatly. When considering a photographic processing system, it must naturally match the characteristics of the photosensitive material. For this reason, it is impossible to process a 3D stereoscopic photograph by using a printing and developing apparatus for ordinary photographs.

This means that it is sufficient to perform processing with a special printing and developing device, but the spread of 3D stereoscopic photography is limited, and it is difficult to collect a large number of processed images. In particular, when processing is performed at retail stores, 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 3D stereoscopic photographs can be processed by using a printing and developing device for processing ordinary photographs, in-store processing is also possible. However, as described above, the characteristics of a normal photograph and a 3D stereoscopic photograph differ greatly from each other, which is not easy.

Various problems arise when the conventional techniques are simply put together to construct an apparatus capable of sharing or jointly using the printing and developing of normal photographs and 3D stereoscopic photographs. For example, in 3D stereoscopic photography, the exposure means is complicated and the development process also takes time, so the performance of the printing and developing apparatus for normal photography deteriorates, and sufficient performance is obtained for both 3D stereoscopic photography and normal photography. It is difficult to provide a processing system with

A more detailed description will be given according to the problem of enabling processing of both 3D stereoscopic photographs and ordinary photographs with one system.

(1) In normal photography, printing is completed by exposure from a fixed direction, but in the case of 3D stereoscopic photography, exposure is required at least 3 to 5 times or more by changing the angle of light rays. A moving mechanism such as photosensitive paper and lens is required.

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

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

Further, when trying to solve the above problems, problems derived from them may be considered. It is an object of the present invention to obtain an automatic printing / developing apparatus and a minilab system capable of processing both 3D stereoscopic photographs and ordinary photographs.

[0023]

To solve the above problems, the present invention takes the following means. First, in order to support various types of printing paper, the following characteristic structure is adopted.

(1) The emulsion surface is selected so that the development processing and the drying can be performed.

(2) Different processing times (development, bleach-fixing,
Stable).

(3) Both the exposure table and the lens, or only the lens, can be moved to correspond to the printing of 3D stereoscopic photographs, and the processing of normal photographs and 3D stereoscopic photographs can be switched.

(4) When the suction type exposure table is adopted, the mechanism is such that the suction force is changed between a normal photograph and a 3D stereoscopic photograph.

An apparatus equipped with these features has a function of processing a 3D stereoscopic photograph in addition to the function of a conventional minilab for processing a normal photograph, and can handle a plurality of different types of photographic paper. Film and 3D stereoscopic film can be processed. In 3D stereoscopic photography, printing paper is conveyed automatically from printing to development in the same way as in normal photography, and the operator need only select the main subject of 3D stereoscopic photography.

The minilab system of the present invention will be described with reference to the drawings. FIG. 1 is a drawing showing an example of the structure of a minilab system of the present invention. Reference numerals in the drawing 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 axis, 21-enlargement lens. The operation of the illustrated device is as follows.
The paper pulled out by the drive roller 3 by the paper roll 6 is cut into a predetermined length by the 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 conveyance direction. Three
During printing of a D stereoscopic photograph, this movement allows the angle of the exposure light beam necessary for printing to be obtained. Further, in conjunction with this operation, the enlargement lens 21 also moves to follow the movement of the exposure table 1. On the other hand, when performing normal printing, the exposure table / lens does not move but is fixed in the paper transport path.

After the exposure is completed, the paper is conveyed again by the exposure table 1 and is sent to the paper processor 11 via the exit roller 5 in both the 3D stereoscopic photograph and the ordinary photograph. Transported by rollers in the paper processor
The processed print comes out from the drying section outlet 2, and the finished print comes out.

Another example of the structure of the minilab system of the present invention is shown in FIG. Reference numerals in the figure are 1-exposure table, 2-drying section, 3-driving roller, 6-paper roll, 11-paper processor, 14-driving motor, 15-feeding section roller, 17-first cutter, 21- They are a stretching lens, a 27-cutter portion, a 31-negative mask, and a 39-loop portion. The paper pulled out by the paper roll 6 reaches the drive roller 3 via the supply unit roller 15 and the exposure table 1. The printing is performed on the exposure table 1, but at the time of printing the 3D stereoscopic photograph, the negative mask 31 and the enlarging lens 21 are moved in the direction of the arrow in the figure to obtain the angle of the exposure light beam necessary for the 3D stereoscopic printing.

Reference numeral 14 is a drive motor for moving the negative mask 31 and the expansion lens 21. This movement is not normally performed during printing of a photograph, and both the negative mask and the lens are fixed and used on the optical axis. It is conceivable that the lens is moved by using a drive motor by means of a feed screw, a feed belt, a rack and pinion, an operating arm and the like.

After the exposure, it is conveyed by the 3D stereoscopic photograph, normal photograph co-driving roller 3 and sent to the paper processor 11 through the loop portion 39. Paper processor 1
When the length of the series of papers sent to 1 reaches a predetermined amount or when the operator finishes the series of printing operations, the first cutter 17 operates to cut the papers. The paper thus sent to the paper processor 11 and processed is passed through the drying section 2 and cut into the print length by the cutter section 27, and the processing is completed.
