Abstract

PURPOSE:To improve workability by automatically discriminating a picture frame of different size, provided mixed in a photographic film, and omitting work for deciding the frame size by an operator. CONSTITUTION:A frame size deciding part 150 is constituted by arranging nine transmitting type concentration sensors 152 in a direction orthogonal to a conveying direction of a negative film 12 to respectively detect transmission concentration along a width direction of the negative film 12. In a memory of a control part 154, a corresponding data to base concentration of the negative film 12 is previously stored to compare a supplied detection value with this base concentration data. That is, in the case of a full size picture frame, all the concentration sensors 152 are within a picture region, so that transmissive concentration of the sensor is low detected, and in the case of a panoramic size picture frame, the transmissive concentration of three upper/lower of the concentration sensors 152 is equalized to the base concentration. As a result, in the control part 154, the present detected picture frame can be discriminated for whether it is in the full size or the panoramic size.

2. Description of the Related Art Generally, images taken with a camera have different sizes on a single negative film, for example,
Panoramic images may be taken in which the field of view is expanded horizontally. There is also a possibility that high-definition size and cinemascope size will appear. The size of this panoramic image is that the vertical direction (width direction of the negative film), which is a part of one frame on negative film, is shortened, and the ratio of the horizontal length to the vertical length is normal. For example, it is about twice as large.

[0003] When printing full size and panoramic size onto photographic paper using the same scale, the operator visually determines the frame size in advance, and changes the printing conditions based on the result of this determination. That's what I do.

Within one lot (for example, one piece or one roll), it is not possible to print each frame one by one by changing the printing conditions for each frame, depending on whether it is a full-size print frame or a panorama-size print frame. When sorting negative films that have a mixture of frames and negative films of the same type, and process negative films that have a mixture of different frame sizes, first perform full-size printing, and then print panorama-size again using a printer specifically designed for panoramic-size printing. It is necessary to extract and print only the print frame.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a schematic diagram of a photographic processing system according to this embodiment.

A cartridge 14 containing a negative film 12 photographed by the camera 10 is sent to a laboratory and first subjected to development processing by a processor 16. Note that the negative film 12 is set in the processor 16 after a plurality of negative films 12 are joined together to form one roll. When the developing process is completed, the negative film 12
The verification work is performed by a negative verification machine 18 (hereinafter referred to as a notcher puncher 18).

The notcher puncher 18 determines correction values for the exposure conditions of the photographed image, inputs the information to the memory card 22 using the writing device 20, and attaches a notch corresponding to each frame. . The correction value for this exposure condition is determined by the operator's visual judgment.
Notches are added automatically.

In the notcher puncher 18, the correction values and the like are recorded on a memory card 22, and this memory card 22 is set into the printer 24 together with the negative film 12.

In the printer 24, the negative film 12 is

A pair of partition plates 344 are provided on the lower surface side of the baking opening 312, allowing the opening area to be changed. The partition plates 344 are located on the same plane with each other and are slidable so that they can be moved into and out of the baking opening 312. The protruding and retracting portion of the partition plate 344 is formed into a frame shape, and the opening area of this frame corresponds to the image frame 12B (panoramic size) of the negative film 12.

[0051] Here, the partition plate 344 to the baking opening 312 is

, the panorama size becomes 2M+α from the panorama size, and the full size becomes 1.5M+α from the panorama size.

The operation of this embodiment will be explained below with reference to FIGS. 10 and 12.
This will be explained according to the flowchart.

First, referring to FIG. 10, the procedure for determining the image frame size by the notcher puncher 18 will be explained.

At step 600, when the notcher puncher 18 is loaded, the process moves to step 602 and transport of the negative film 12 is started. Next step 604
Then, the edge of the image frame is detected by the image reading section 138, and then in step 606, the density sensor 152 arranged in the width direction of the negative film 12 detects the transmissive density of the negative film 12 in the width direction. Next step 6
In step 08, the frame size is determined based on this detected value.

FIG. 11 shows the frame size determination control routine in step 608 of FIG. In step 700, the detected values are sequentially supplied to the sample and hold circuit 158 by the multiplexer 156, and
When one batch of data is completed (step 702), each data is A/D converted and then supplied to the control unit 154 (
Step 704). If there is more than one piece of data corresponding to one image frame, all of the data is sent to the control unit 1.
54 (step 706), the control section 154 moves to step 708, reads out the base density data of the negative film 12 from the memory, and then compares it with the detected data in step 710 to determine the frame size. do.

That is, since the base density area in the width direction of the negative film 12 is different between full size and panoramic size, the frame size can be determined based on the difference in this area.

In the next step 712, the determination result is recorded in the memory of the temporary control section 154, and the process returns to the main routine.

As shown in FIG. 10, when the frame size determination in step 608 is completed, the process proceeds to step 610, where each image frame is positioned in the negative film verification/notching section 140, and the process proceeds to step 612, where the notching is performed. is given, and the test result is input in step 614.

In the next step 616, the input test result is recorded on the memory card, and then in step 618, the test result is temporarily stored in the control section 154 corresponding to the image frame currently positioned in the negative film/notching section 140. The result of determining the frame size to be used is recorded on the memory card 22.

[0067] In the next step 620, it is determined whether or not the verification of all image frames has been completed, and in the case of a negative determination,
The process moves to step 602, and if the determination is affirmative, this routine ends.

Next, FIG. 12 shows the processing procedure in the printing device.
Explain according to the following.

As shown in FIG. 12, in step 500, information on the next image frame to be burned is read from the memory card 22, and the process proceeds to step 502, where the type of image frame (full image frame) is determined from the read information. size or panoramic size).

In step 502, if it is determined that the size is full size, the process moves to step 504 and flag F is set (1), and if it is determined that the size is panorama size, the process moves to step 506 and the flag F is set (1). F is reset (0) and the process moves to step 508.

In step 508, it is determined whether the printing conditions currently set in the printer 24 match the printing conditions of the next image frame to be printed. That is, if they match, there is no need to change the burning conditions; on the other hand, if they do not match, it is necessary to change the burning conditions.

If it is determined in step 508 that the burning conditions match, the process proceeds to step 510, where it is determined whether flag F is set. If the determination in step 510 is affirmative, the process proceeds to step 51.
2, full-size to full-size conveyance (conveyance distance M+α) is performed. If a negative determination is made in step 510, the process proceeds to step 514, where conveyance between panorama size and panoramic size (conveyance distance 2M+α) is performed.

In the next step 516, negative film 1 is
2, the image frame to be printed is positioned at the printing position, then photometry is performed in step 518, and step 5
The exposure amount is calculated in step 20. In the next step 522, a baking process is performed. At step 524, it is determined whether or not one roll of negative film 12 has been completed. If the determination is negative, the process moves to step 500 to prepare for printing the next image frame. Furthermore, in step 524, if it is determined that the burning process for all image frames has been completed (affirmative determination),
Processing ends.

If it is determined in step 508 that the printing conditions do not match, the process moves from step 508 to step 526, where it is determined whether flag F has been set, and whether the determined image frame is full or not. Select size or panorama size.

[0075] In step 526, it is determined that the size is full size (F=
1), in step 528 print mask 2 is
04 screen 262 is rolled out and reset to the full size mask area. Next, in step 530, the partition plate 344 of the negative carrier 220 is evacuated from the printing opening and reset to the printing opening for full size. Next, the process proceeds to step 532, where the lens 237 is driven and reset to the full-size (standard) magnification position, and the process proceeds to step 534.

If it is determined in step 526 that the size is panoramic (F=0), then in step 536 the screen 262 of the print mask 204 is rolled up and reset to the panoramic size mask area. Next, in step 538, the partition plate 344 of the negative carrier 220 is placed in the printing aperture, and the printing aperture for panorama size is reset. Next, the process proceeds to step 540, where the lens 237 is driven and reset to the panoramic size magnification position, and the process proceeds to step 534.

In step 534, the photographic paper is divided between different sizes (full size - panoramic size or panoramic size -
(full size) (transport distance 1.5 M+α), and the process moves to step 516.

As described above, in this embodiment, the type of image frames (full size or panoramic size) that are sequentially conveyed is
Since the printing conditions can be changed according to the printing conditions, there is no need to reset the negative film 12, and one lot (one roll or one film) can be printed in one batch process.
The negative film 12 can be subjected to printing processing. Therefore, work efficiency is high, and a dedicated panoramic printer is not required.

The amount of correction for the exposure amount determined by photometry of the image frame positioned at the printing position is determined by determining the amount of color correction and the amount of density correction in advance through verification using the notcher puncher 18, as shown in FIG. 9(A). It is stored in each frame area of the memory card 22. That is, the memory card 22 stores the frame number of each frame, the amount of color correction and the amount of density correction as necessary, and also records data for determining whether the frame is full size or panoramic size. In this case, since there are two types to be determined, data is omitted in the case of full size.

The information in this memory card 22 is shown in FIG.
As shown in B), the printing conditions (print mask position, negative mask position, lens position, and photographic paper feed amount) for each frame may be stored.

[0081] In this embodiment, the frame size determination section 1
50 is disposed adjacent to the image reading section 138 of the notcher puncher 18, and the determination result is stored in the memory card 22, so that the frame size determination result is read from the memory card 22 during the printing process. , the frame size determination section 150 may be disposed upstream of the printing position of the printer 24.

Effects of the Invention As explained above, the method and device for determining the image frame size of photographic film according to the present invention can automatically distinguish between full-size print frames and other-size print frames such as panoramic images mixed in a full-size photographic film. This has the excellent effect of improving work efficiency by omitting the work of determining the frame size by the operator.
