BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image of a photographic film for determining 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 photographic printing apparatus that changes printing conditions based on the determination result of a frame size determination apparatus.

[0002]

2. Description of the Related Art Generally, the size of an image captured by a camera is different on one negative film, for example,
A panoramic image whose field of view is horizontally expanded may be captured. High-definition size and cinemascope size may also appear. The size of this panoramic image is shortened in the vertical direction of one frame on the negative film (width direction of the negative film), and the ratio of the length in the horizontal direction to the length in the vertical direction is larger than that of a normal image. It has doubled.

Here, in the case of performing the printing process on the printing paper on the same scale of the full size and the panoramic size, the operator visually judges the frame size in advance and changes the printing condition based on the judgment result. I am trying.

In such a case, in the conventional printing apparatus,
Within one lot (for example, one roll or one roll), it is not possible to change printing conditions for each frame and print one frame at a time depending on whether it is a full size print frame or a panorama size print frame. When sorting negative film with mixed film and negative film with no mixed film, and processing negative film with different frame sizes, first perform full size printing, then use a dedicated panorama size printing printer again to perform panorama size printing. Only the frames need to be extracted and printed.

[0005]

However, in the printing of a film in which a step of determining the frame size and sorting is added, and in which a full-size print frame and another size print frame such as a panorama are mixed, the film is set. Must be done twice.

In consideration of the above facts, the present invention automatically discriminates between full-size print frames mixed in photographic film and different-size print frames such as panoramas, and omits the frame size judgment work by the operator, thereby improving workability. It is an object of the present invention to obtain a photographic printing apparatus capable of improving the image quality.

[0007]

In order to achieve the above object, the invention of claim 1 is such that a negative film guide wall for guiding a negative film is formed and a negative carrier for automatically conveying the negative film. Is provided to determine the size of each image frame of the negative film before starting printing, based on the judgment result of the frame size judgment section, the means to automatically set the enlargement ratio and the feeding amount of the photographic paper are set automatically. And means for doing so are provided.

According to a second aspect of the present invention, the frame size determination section of the first aspect includes a plurality of transmission type density sensors arranged in a direction orthogonal to the negative film transport direction, and the output of the density sensor A full size or a panorama size is determined based on the difference between the base density regions of the image frames detected more.

According to a third aspect of the invention, the frame size determination section according to the first or second aspect of the invention is arranged upstream of the printing position of the photographic printing apparatus.

According to a fourth aspect of the present invention, the mask area of the photographic paper is defined in the longitudinal direction of the photographic paper according to the invention of any one of the first to third aspects, based on the determination result of the frame size determination section. And a means for changing the mask area of the negative film in the width direction of the negative film based on the judgment result of the frame size judging section.

[0011]

According to the first aspect of the present invention, when a negative film in which different frame sizes are mixed is automatically conveyed by the negative carrier, a frame size determination unit for determining the size of each image frame of the negative film before the start of printing. On the basis of the determination result, the enlargement ratio is automatically set, and the photographic paper feed amount is also automatically set. Thereby, the discrimination work by the operator can be omitted, so that the workability is improved.

The frame size determination unit is provided with a plurality of transmission type density sensors arranged in a direction orthogonal to the direction in which the negative film is conveyed, as in the invention of claim 2, and an image detected from the output of the density sensor. It can be configured to determine whether the size is the full size or the panorama size based on the difference between the base density regions of the frames. The frame size determination unit is defined in claim 3.
The invention can be arranged upstream of the printing position of the photographic printing apparatus.

The operation of this embodiment will be described below with reference to FIGS.
The flow chart will be described. 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 notcher puncher 18 is loaded, the process proceeds to step 602 and the negative film 12 is started to be conveyed. Next step 604
Then, the edge of the image frame is detected by the image reading unit 138, and then the density sensor 152 arranged in the width direction of the negative film 12 detects the transmission density in the width direction of the negative film 12 at step 606. Next, step 6
At 08, the frame size is determined based on this detected value.

FIG. 11 shows a frame size determination control routine in step 608 of FIG. In step 700, the detected value is sequentially supplied to the sample 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 controller 154 (step 704). When there is a plurality of data for one image corresponding to one image frame, when all the respective data are input to the control unit 154 (step 706), the process proceeds to step 708, and the control unit 154 reads the negative from the memory. The base density data of the film 12 is read out, and then in step 710, it is compared with the detected data to determine the frame size.

That is, since the base size area in the width direction of the negative film 12 is different between the full size and the panorama size, the frame size can be discriminated by the difference in this area.

At 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 process moves to step 610, where each image frame is positioned in the negative film verification / notch imparting section 140, and then to step 612. Is added and the test result is input in step 614.

At the next step 616, the inputted test result is recorded on the memory card, and then at step 618, the image frame currently positioned in the negative film / notch imparting section 140 is temporarily stored in the control section 154 and is dealt with. The determination result of the frame size to be recorded is recorded in the memory card 22.

At the next step 620, it is judged whether or not the verification of all the image frames has been completed, and in the case of a negative judgment,
If the determination is affirmative, then this routine ends.

Next, the processing procedure in the printing apparatus is shown in FIG.
Follow the explanation below. As shown in FIG. 12, step 50
At 0, the information of the image frame next to the printing position is read from the memory card 22, the process proceeds to step 502, and the type (full size or panorama size) of the image frame is discriminated from the read information.

If it is determined in step 502 that the size is full size, the process proceeds to step 504 and the flag F is set (1). If it is determined that the size is panoramic, the process proceeds to step 506 and the flag is set. F is reset (0) and the process proceeds to step 508.

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

If it is determined in step 508 that the printing conditions are the same, the process proceeds to step 510 and it is determined whether or not the flag F is set.
If an affirmative decision is made in step 510, step 51
Then, the process proceeds to 2 to carry between full size and full size (conveyance distance M + α). If a negative determination is made in step 510, the process moves to step 514 to carry out panorama size-panorama size conveyance (conveyance distance 2M + α).

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

If it is determined in step 508 that the printing conditions do not match, step 508 to step 5
In step 26, it is determined whether the flag F has been set, and whether the determined image frame is full size or panoramic size is selected.

In step 526, it is determined that the size is full size (F =
If 1), the print mask 2 is printed at step 528.
The screen 262 of 04 is unwound, and is set again in the mask area for full size. Next, at step 530, the partition plate 344 of the negative carrier 220 is retracted from the baking opening and reset to the baking opening for full size. Next, the process proceeds to step 532, the lens 237 is driven to reset to the full-size (standard) magnification position, and the process proceeds to step 534.

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

In step 534, the printing papers of different sizes (full size-panorama size or panorama size-
It is conveyed in full size (conveyance distance 1.5 M + α) and moves to step 516.

As described above, in this embodiment, the types of image frames sequentially conveyed (full size or panoramic size)
Depending on the printing conditions, the printing conditions can be changed, so there is no need to reset the negative film 12, and one lot (1 roll or 1 roll) can be processed once.
The negative film 12 can be baked. Therefore, the work efficiency is good, and the panorama printer is not necessary.

As for the correction amount with respect to the exposure amount by the 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 verification by the notcher puncher 18, and as shown in FIG. 9 (A). 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 and the color correction amount and the density correction amount as necessary, and also records data for determining the full size or the panorama size. In this case, since there are two types to be discriminated, data is omitted in the full size.

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 printing paper feed amount) for each frame may be stored.

In the present embodiment, the frame size determination unit 1
50 is arranged adjacent to the image reading unit 138 of the notcher puncher 18, and the determination result is stored in the memory card 22, so that the determination result of the frame size is read from the memory card 22 during the printing process. The frame size determination unit 150 may be arranged on the upstream side of the printing position of the printer 24.

[0079]

As described above, according to the photographic printing apparatus of the present invention, since the full-size print frames mixed in the photographic film and the different-size print frames such as the panorama are automatically discriminated, the printing is performed. This has an excellent effect that the workability can be improved by omitting the frame size determination work by the operator.
