DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image frame of a photographic film for judging the size of an image frame recorded on a photographic film when a normal size frame and another size frame such as a panorama are mixed. The present invention relates to a frame size determination method and a frame size determination method.

[0002]

2. Description of the Related Art Generally, the size of an image captured by a camera is different on a single negative film, for example,
A panoramic image whose field of view is expanded in the horizontal direction may be captured. Also, there is a possibility that a high-definition size or a cinemascope size will appear. The size of this panoramic image is such that the vertical direction (width direction of the negative film), which is a part of one frame on the negative film, is shortened, and the ratio of the horizontal length to the vertical length is normal. It is larger, for example, about twice.

Here, when printing a full size and a panoramic size on the photographic paper on the same scale, an operator previously determines the frame size visually and changes the printing conditions based on the determination result. Like that.

[0004] In such a case, in the conventional printing apparatus,
Within one lot (for example, one or one roll), it is not possible to change the printing conditions for each frame and print one frame at a time, depending on whether the frame is a full-size print frame or a panorama-size print frame. When sorting negative film with the same type of negative film and negative film with different frame sizes, first perform full-size printing, and then again use a printer dedicated to panoramic size printing. It is necessary to extract only print frames and print them.

[0005]

However, a step of judging a frame size is added, and when printing a film in which a full-size print frame and another size print frame such as a panorama are mixed, the film must be set twice. It must be made.

In view of the above facts, the present invention considers full-size print frames and panorama-size prints mixed in photographic film.
It is an object of the present invention to provide a method and apparatus for determining an image frame size of a photographic film, which can automatically determine a lint frame, omit a frame size determination operation by an operator, and improve workability.

FIG. 1 is a schematic diagram of a photographic processing system according to the present embodiment.

The patrone 14 containing the negative film 12 photographed by the camera 10 is sent to a laboratory, where it is first subjected to a developing process by a processor 16. The negative film 12 is set to the processor 16 after joining a plurality of negative films 12 to form a single roll. When the development process is completed, the negative film 12
Is inspected by a negative inspection machine 18 (hereinafter, notcher puncher 18).

The notch puncher 18 determines a correction value of an exposure condition of a photographed image, inputs the information to a memory card 22 by a writing device 20, and adds a notch corresponding to each frame. . The determination of the correction value of the exposure condition is performed by visual judgment of the operator,

The operation of this embodiment will be described below with reference to FIGS.
This will be described according to the flowchart of FIG.

First, the procedure for determining the image frame size by the notcher puncher 18 will be described with reference to FIG.

In step 600, when the notch puncher 18 is loaded, the process proceeds to step 602, and the transport of the negative film 12 is started. Next step 604
Then, the edge of the image frame is detected by the image reading unit 138, and then in step 606, the transmission density in the width direction of the negative film 12 is detected by the density sensors 152 arranged in the width direction of the negative film 12. Then step 6
At 08, the frame size is determined based on the detected value.

FIG. 11 shows a 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,
When the data for one time is completed (step 702), the data is A / D converted and then supplied to the control unit 154 (step 704). If there is a plurality of data for one time corresponding to one image frame, the process proceeds to step 708 when all the data are input to the control unit 154 (step 706), and the control unit 154 causes the negative from the memory. The base density data of the film 12 is read out, and then the frame size is determined in step 710 by comparing it with the detected data.

That is, since the base density region in the width direction of the negative film 12 is different between the full size and the panorama size, the frame size can be determined from the difference between these regions.

In the next step 712, the discrimination 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 flow advances to step 610 to position each image frame to the negative film verification / notch adding section 140, and then to step 612 to perform notch. Is given and the test result is input in step 614.

In the next step 616, the entered test result is recorded on the memory card, and then in step 618, the image frame which is temporarily stored in the control section 154 and corresponds to the image frame currently positioned in the negative film / notch applying section 140 is stored. The result of the frame size determination is recorded in the memory card 22.

In the next step 620, it is determined whether or not the verification of all the image frames has been completed.
The flow shifts to step 602, and if the determination is affirmative, this routine ends.

Next, the processing procedure in the printing apparatus will be described with reference to FIG.
It will be described according to the following.

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

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

In step 508, it is determined whether or not the printing condition currently set in the printer 24 matches the printing condition of the image frame to be printed next. That is, if they match, it is not necessary to change the printing conditions. Conversely, if they do not match, it is necessary to change the printing conditions.

If it is determined in step 508 that the printing conditions match, the flow shifts to step 510 to determine whether or not the flag F has been set.
If an affirmative determination is made in step 510, the process proceeds to step 51.
Then, the process proceeds to step S2 to carry out the conveyance between the full sizes (full length M + α). If a negative determination is made in step 510, the flow shifts to step 514 to perform transport between panoramic sizes (panel size 2M + α).

In the next step 516, the negative film 1
2, the image frame to be printed is positioned at the printing position, and photometry is performed at step 518, and
At 20, the exposure is calculated. In the next step 522, a printing process is performed. In step 524, it is determined whether the one-roll negative film 12 has been completed. If the determination is negative, the process proceeds to step 500 to prepare for the next image frame printing. In step 524, when it is determined that the printing process of all the image frames has been completed (positive determination),
The process ends.

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

At step 526, it is determined that the image is full size (F =
If 1), the print mask 2 is set in step 528.
The screen 262 of No. 04 is unwound and set again in the mask area for full size. Next, in step 530, the partition plate 344 of the negative carrier 220 is retracted from the printing opening, and is set again in the printing opening for the full size. Next, the flow shifts to step 532, in which the lens 237 is driven and reset to the full-size (standard) magnification position, and the flow shifts to step 534.

If it is determined in step 526 that the size is a panorama size (F = 0), the screen 262 of the print mask 204 is taken up in step 536 and set in a panorama size mask area. Next, at step 538, the partition plate 344 of the negative carrier 220 is arranged at the printing opening, and is set again at the printing opening for panorama size. Next, the flow shifts to step 540, in which the lens 237 is driven to reset the panorama size magnification position, and the flow shifts to step 534.

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

As described above, in the present embodiment, the type of the image frames sequentially conveyed (full size or panorama size)
In this case, it is possible to change the printing conditions according to the printing conditions, so that the operation of resetting the negative film 12 is unnecessary, and one batch (one roll or one roll) can be obtained by one batch processing.
Of the negative film 12 can be performed. Therefore, work efficiency is good and a printer dedicated to panorama is not required.

As for the correction amount for the exposure amount by photometry of the image frame positioned at the printing position, the color correction amount and the density correction amount are determined in advance by the test using the notcher puncher 18, and as shown in FIG. It is stored in the area of each frame of the memory card 22. That is, the memory card 22 stores the frame number of each frame, the color correction amount and the density correction amount as required, and records data for determining whether the frame is the full size or the panorama size. In this case, since there are two types to be discriminated, data is omitted in the case of the full size.

The information in the 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.

In this embodiment, the frame size determination unit 1
50 is arranged adjacent to the image reading unit 138 of the notch 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. Alternatively, the frame size determination unit 150 may be disposed upstream of the printing position of the printer 24.
