Abstract

PURPOSE:To efficiently print a film, providing frames mixed of different print assigning size, through a one-time batch process by determining a printing order based on distribution of different print size recorded in the film of one roll. CONSTITUTION:When a developing process is finished, a negative film 12 is detected by a negative detector 18. That is, in the negative detector 18, a corresponding exposure condition is input to a memory card 22 by a write device 20 by applying a notch to each frame and also discriminating a kind of the frame recorded in the memory card 22. In a printer 24, the negative film 12 is conveyed simultaneously reading information from the memory card 22 by a read device 26, and distribution of the frame is analyzed from this information to determine an optimum printing order. For instance, in the case of providing a normal size and a panoramic size mixed at random, the one size is printed first to rewind the film, and when the other size is printed, only one time switching is required for a printing condition.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photographic printing method and a photographic printing apparatus for printing onto photographic paper image frames of one film in which image frames of different specified print sizes coexist.

0002

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.

[0003] The size of a panoramic image is that on negative film, the vertical direction (width direction of the negative film), which is a part of one frame, is shortened, and the ratio of the horizontal length to the vertical length is usually small. It is larger, for example, about twice as large.

[0004] When printing full size and panoramic size onto photographic paper using the same scale, the enlargement magnification when printing panoramic size print frames is higher than the enlargement magnification when printing full size print frames. It is necessary to increase the mask area of the negative film and the printing range of the photographic paper. That is, it is necessary to change the mask area of the negative film and the conveyance distance of the photographic paper according to each size.

[0005] In such cases, conventional printing equipment
Within one lot (for example, one piece or one item), depending on whether it is a full-size print frame or a panorama-size print frame, it is not possible to print each frame one by one by changing the printing conditions for each frame. After printing, it is necessary to extract and print only the panoramic size print frames using a printer dedicated to panoramic size printing.

[0006]

However, when printing a film in which full-size print frames and other-size print frames such as panoramas coexist, the film must be set twice. In other words, the process cannot be completed in one batch process.

In consideration of the above facts, the present invention is capable of printing a film containing a mixture of image frames of different specified print sizes while changing the printing conditions to correspond to each frame, and is efficient in one batch process. It is an object of the present invention to obtain a photoprinting method and a photoprinting device that allow good printing.

[0008]

[Means for Solving the Problems] The invention as set forth in claim 1 is a photographic printing method for printing onto photographic paper image frames of one film in which image frames of different designated print sizes are mixed. , the printing order is determined based on the distribution of the types of image frames with different print sizes on the film for one case, and the printing order is determined based on the distribution of the types of image frames with different print sizes on the film, and
The present invention is characterized in that the printing process is performed by switching printing conditions including the feeding amount of the photographic paper and the enlargement magnification in accordance with the printing order.

The invention according to claim 2 is the invention according to claim 1, wherein the designated print size of the image frame recorded on the film is detected before the printing step and stored in a storage medium, is set in a printing device together with the film.

The invention as set forth in claim 3 is a photographic printing method for printing onto photographic paper image frames of one film in which image frames of different designated print sizes coexist, wherein the image frames of the same designated print size are printed. After printing the image frame, go back and print another image frame of the designated print size, and print by switching the printing conditions including the film mask area, photographic paper mask area, feeding amount of the photographic paper, and enlargement magnification at each conveyance. It is characterized by processing.

[0011] The invention according to claim 4 is a photographic printing apparatus for printing onto photographic paper image frames of one film in which image frames having different specified print sizes coexist, printing condition switching means for switching printing conditions including a paper mask area, the feeding amount of the photographic paper, and the enlargement magnification for each of the different designated print sizes; a designated print size determining means for determining the designated print size; a sorting means for sorting the same specified print size based on the results determined by the size discrimination means; a positioning means for sequentially positioning the sorted image frames of the same type to a printing position; control means for rewinding the film and controlling the printing condition switching means to switch to the printing conditions for the type of image frame to be selected next; have.

0012

According to the first aspect of the invention, the printing order is determined based on the distribution of different print sizes recorded on one film. For example, if one piece of film contains a mixture of full-size image frames and image frames of different sizes such as panoramas, and only the first frame and last frame are of different sizes such as panoramas, switch the printing conditions. Since the images only need to be printed twice, it is efficient to print them in the order recorded on the film. On the other hand, if full size and other sizes such as panorama are randomly mixed, it is better to print one size first, then rewind the film and print the other size because it is easier to switch the printing conditions. It only needs to be done once, which is efficient. In this way, the printing order can be determined based on the distribution of image frame types for one film.
Work efficiency can always be optimized.

[0013] According to the second aspect of the invention, before the printing process, for example, at the time of verification using a notcher puncher, the specified print size of the image frame is detected and stored in the storage medium. By setting this stored storage medium together with the film into a printing device, it is possible to recognize the distribution state of image frames on the film before the printing process.

According to the third aspect of the invention, after printing an image frame of the same specified print size, the process returns to print another image frame of the specified print size. This makes it possible to reduce the number of changes in printing conditions, improving work efficiency.

[0015] When returning, it is possible to return to the beginning of one film or to the beginning of unprocessed image frames.

According to the fourth aspect of the invention, the designated print size is determined by the determining means. Based on this determination result, image frames of the same designated print size are selected. Here, the film is transported, and only the selected image frames are sequentially positioned at the printing position, and the same image frames on one film are subjected to printing processing.

Next, the film is rewound once, other types of image frames are selected, the printing conditions are changed, and the printing process is performed in the same manner as above. In this way, by sorting the image frames and performing the printing process on each image frame of the same type, it is possible to reduce the work of switching the printing conditions, and
Since the printing process can be performed in one batch process with the film set, work efficiency is improved.

6 is formed. A printing opening 312 is provided in the longitudinal center of the negative film transport path 306, and the printer 2
4 is used as an irradiation port for the light beam from the light source 202 provided at 4. The size of this printing opening 312 is determined by the size of the negative film 12.
The size is the same as the full-size image frame 12A. A printing opening 312 is provided in the negative film transport path 306.
Upstream side (left direction in Figure 6) and downstream side (right direction in Figure 6)
The conveying rollers 320, 322, and 324 carry the negative film 1.
It is arranged corresponding to the back surface (lower surface) of 2. Each of the conveyance rollers 320, 322, and 324 is driven in the same rotational direction and at the same rotational speed.

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.

[0053] Here, the partition plate 344 to the baking opening 312
When protruding, both ends of the printing opening 312 in the vertical direction (width direction of the negative film 12) are blocked from light, so that the remaining opening area is made equal to the size of the panoramic image frame of the negative film 12. It has become.

That is, when the partition plate 344 is pulled toward the front (first position), full-size image frame 1
2A and is pushed to the back (second
position), it will be adapted to a panoramic size image frame. The partition plate 344 is slid by a motor (not shown).

The opening/closing cover 304 has a housing-like cover main body 390 whose lower end is pivotally supported by a bar 392 fixed to the pedestal 302, and can be opened and closed with respect to the pedestal 302 around this bar 392. ing.

A through hole 396 corresponding to the burning opening 312 is provided at the bottom of the cover body 390. The cover body 390 also has an upper guide base 398 located at a position corresponding to the negative film transport path 306 in the closed state.
is attached, and a negative film guide wall 402 is integrally formed so that a gap is created between the tip of the guide wall 402 and the guide surface 308. Further, this gap size is slightly larger than the wall thickness of the negative film 12 to ensure a conveyance path for the ends in the width direction of the negative film.

Idle rollers 410, 412, 414 are stretched between the guide walls 402, corresponding to the conveyance rollers 320, 322, 324, and the opening/closing cover 304 is closed. By being
The negative film 12 is held between the idle rollers 410, 412, 414 and the transport rollers 320, 322, 324 so that transport force can be transmitted to the negative film 12.

At the center of the strong base 404 in the negative film transport direction, a strong mask 420 is disposed, which is movable relative to the strong base 404 and has an opening at a position corresponding to the through hole 396. Atsupa mask 420 is attached to Atsupa base 404 via the sloped side surface.
It is fixed to a mask base 422 arranged on the back side of the mask. The mask base 422 is disposed over almost the entire bottom surface of the cover body 390, and covers the entire bottom surface of the cover body 390.
3 is fixed. When the solenoid main body 423 is energized, the Atsupah mask 420 is moved relative to the Atsupah base 404 and can be brought into close contact with the printing opening 312 of the negative film transport path 306, thereby holding the negative film 12 positioned on the optical axis P. It is now possible to do so.

Next, the enlargement magnification by the lens 237 is changed by the driver 239, which is driven so that the enlargement magnification is larger for panoramic size than for full size, and its position is constant. Therefore, two positions, a full-size position and a panoramic-size position, may be stored in advance, and the positioning may be performed to either position according to a signal from the memory card 22.

Finally, the conveyance distance of the photographic paper 28 is as shown in FIG. 7. If the screen interval is α, the conveyance distance from full size to full size is M+α, and the conveyance distance between the other is full size. The panoramic size is 1.5 M+α
, 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 the flowchart shown in FIG. It is assumed that the type of image frame (in this embodiment, full size or panoramic size) is determined by the notcher puncher 18, recorded on the memory card 22, and loaded into the reading device 26 of the printer 24.

In step 500, the variable N is set to 1, and then the process moves to step 502 to read the memory card 22.
Read information from. In the next step 504, the distribution of frames in the image is analyzed from the read information, and in the next step 506, the optimum printing order is determined based on the analysis results. Here, if the image frame distribution is as shown in Fig. 9(A), that is, only the first and last image frames are panorama size and all the others are full size, then the printing conditions only need to be switched twice. , it can be determined that it is optimal to print the images in the same order as they were printed on the negative film 12. Furthermore, if the image frames have a distribution as shown in FIG. 9(B), it can be determined that it is optimal to select and print image frames of the same type. In step 506, the printing order is determined according to the distribution of image frames.

In the next step 508, the N-th printing conditions are read out, and the process moves to step 510. At step 510, it is determined whether or not the burning conditions are the same as the previous one. If the determination is negative, the process moves to step 512, where the burning conditions are reset, and the process moves to step 514. If an affirmative determination is made in step 510, there is no need to change the burning conditions, so the process skips step 512 and proceeds to step 514.

In step 514, image frame positioning, photometry, exposure amount calculation, etc. are performed, and printing processing is performed.

When the baking process is completed in step 514,
The process moves to step 516, and it is determined whether or not one negative film 12 has been completed.If the judgment is negative, the process moves to step 518, where the variable N is incremented, and the process moves to step 508, where the above-mentioned affirmative judgment is made. repeat. If an affirmative determination is made in step 516, the process proceeds to step 520, where it is determined whether or not it is necessary to rewind the negative film 12. This is because in the case of the image frame printing order as shown in Figure 9(B), image frames of a different type (panoramic size) are passed and only image frames of the same type (full size) are printed first. It is necessary to rewind the negative film 12 once. Therefore, if the determination is affirmative, step 51
Move to 8. Furthermore, if the determination is negative, the process ends.

In this way, since the printing order is determined based on the distribution of image frames recorded on one negative film 12, optimum work efficiency can be obtained. That is, it is possible to select the firing order that requires the least number of changes in the firing conditions.

(Modification 1) In the above embodiment, the printing order of the image frames recorded on the negative film was determined in advance, but when the printer 24 detects the size of the image frames,
First, print only the full-size image frame 12A, rewind it all, and then print the panorama-size image frame 12B.
It is also possible to set a processing procedure so that only the image is printed. The procedure will be explained below according to the flowchart of FIG.

First, in step 600, the flag G is reset, and then the process moves to step 602, where the printing conditions for full size are set. This full-size printing condition is such that the screen 262 of the print mask 204 is unrolled and set in the full-size mask area, the partition plate 344 of the negative carrier 220 is retracted from the printing opening, and the screen 262 of the print mask 204 is set in the full-size printing opening. set, and drive the lens 237 to set it to the full-size (standard) magnification position. In the next step 604, information on the image frame is read from the memory card 22, and the process moves to step 606 to determine the type of image frame. If it is determined in step 606 that the size is full size, a flag F is set in step 608, and if it is determined that it is panoramic size, it is set in step 61.
The flag F is reset at 0 and the process moves to step 612.

In the next step 612, if it is determined that the flag G is in the reset state, that is, it is the first conveyance, the process moves to step 614, and the type of image frame is determined depending on whether the flag F is set or not. If it is full size, the process moves to step 616, the photographic paper is conveyed a distance M, that is, one full size image frame, and the process moves to step 620. If it is determined in step 614 that the size is panoramic, the process moves to step 618.
The photographic paper is conveyed a distance of 3M, that is, the distance that passes the panoramic size image frame, and the process moves to step 604.

In the next step 620, the negative film 1
2, the image frame to be printed is positioned at the printing position, then photometry is performed in step 622, and step 6
In step 24, the exposure amount is calculated. In the next step 626, a baking process is performed. In step 628, it is determined whether one roll of negative film 12 has been completed, and if the determination is negative, the process moves to step 604.

[0071] If the determination in step 628 is affirmative, the process proceeds to step 630, where it is determined whether or not the flag G is set. If the determination is negative, this is the first conveyance, so the process proceeds to step 630. The process moves to step 632 to rewind the negative film 12 and photographic paper, and then, after setting the flag G in step 634, the process moves to step 636.
After setting the printing conditions for panorama size, the process moves to step 604. The printing conditions for this panorama size are as follows:
2 and set it in the panoramic size mask area, place the partition plate 344 of the negative carrier 220 in the printing aperture, set it in the panoramic size printing aperture, and drive the lens 237 to set the magnification position for the panoramic size. Set it to

At step 612, it is determined that flag G is set, that is, it is the second conveyance, and the process proceeds to step 638, where it is determined whether flag F has been reset. If an affirmative determination is made in step 638, that is, if it is determined that the size is panoramic, the process moves to step 640, where one panoramic size is transported (distance 2M).
The process moves to step 620. Further, if the determination in step 638 is negative, that is, if it is determined to be full size, the process proceeds to step 642, where the conveyance (distance M) is carried out to pass the full size, and the process proceeds to step 604.

In this way, one lot of negative film is
By winding it up again and transporting it twice at the end of one round of transport, it is only necessary to switch the baking conditions once per lot, improving work efficiency. Also, since the image frames can be printed onto photographic paper in the order they are recorded,
Negative films 12 requested by a plurality of users can be printed continuously, and work efficiency such as sorting is improved.

[0074] Note that the position of the panoramic size image frame is memorized during the first transport, and during the second transport,
Based on the stored position information, panoramic size image frames may be directly transported and positioned.

[0075] In the flowchart shown in Fig. 10,
When printing the next negative film 12 after finishing one batch, the settings were changed to the full-size printing conditions, but the settings for the first batch were set to the panorama-size printing conditions. If you print the next item from the panoramic size after completing the printing, you can reduce the number of changes in printing conditions and further improve work efficiency. (Modification 2) According to the flowchart shown in FIG. 11, the negative film 12
A different processing procedure from Modification Example 1 will be described, in which the image is rewound once and the full size and panoramic size are printed separately.

First, in step 700, the flag G is reset, and then the process moves to step 702, where the printing conditions for full size are set. This full-size printing condition is such that the screen 262 of the print mask 204 is unrolled and set in the full-size mask area, the partition plate 344 of the negative carrier 220 is retracted from the printing opening, and the screen 262 of the print mask 204 is set in the full-size printing opening. set, and drive the lens 237 to set it to the full-size (standard) magnification position. In the next step 704, information on the image frame is read from the memory card 22, and the process moves to step 706 to determine the type of image frame. If it is determined in step 706 that the image is full size, a flag F is set in step 708, and if it is determined that it is panoramic size, it is determined in step 71.
The flag F is reset at 0 and the process moves to step 712.

In the next step 712, if it is determined that the flag G is in the reset state, that is, it is the first conveyance, the process moves to step 714, and the type of image frame is determined depending on whether the flag F is set or not. If it is full size, the process moves to step 716, the photographic paper is conveyed a distance M, that is, one full size image frame, and the process moves to step 720. If it is determined in step 714 that the size is panoramic, the process moves to step 704.

In the next step 720, the negative film 1
2, the image frame to be printed is positioned at the printing position, then photometry is performed in step 722, and step 7
In step 24, the exposure amount is calculated. In the next step 726, a baking process is performed. In step 728, it is determined whether one roll of negative film 12 has been completed, and if the determination is negative, the process moves to step 704.

[0079] If an affirmative determination is made in step 728, the process proceeds to step 730, where it is determined whether or not flag G is set. If a negative determination is made, this is the first conveyance, so step 730 is proceeded to. Step 732 rewinds the negative film 12, then step 734 sets flag G, step 736 sets the printing conditions for panoramic size, and step 704
Move to. The printing conditions for this panoramic size are as follows: wind up the screen 262 of the print mask 204, set it in the panoramic size mask area, place the partition plate 344 of the negative carrier 220 in the printing opening, and place the partition plate 344 in the printing opening for the panoramic size. and drive the lens 237 to set it to the panoramic size magnification position.

At step 712, it is determined that flag G is set, that is, it is the second conveyance, and the process proceeds to step 738, where it is determined whether flag F has been reset. If an affirmative determination is made in step 738, that is, if it is determined that the size is panoramic, the process proceeds to step 740, where one panoramic size is transported (distance 2M).
The process moves to step 720. Further, if the determination in step 738 is negative, that is, if it is determined that the size is full size, the process moves to step 704.

In this embodiment, the type of image frame of the negative film 12 is recorded on the memory card 22, and the type of image frame is determined by the printer 24 from the information on the memory card 22. If it is not necessary to recognize the distribution state, as shown in FIG. 12, an optical mark (bar code 30 or exposure mark 32) or the like is attached to the base of the negative film 12, and this mark is detected. , the above processing may be performed. Alternatively, as shown in FIG. 13, the edge portion of the image frame may be detected based on the density distribution measured by the light receiver 254, and whether the frame is full size or panoramic size may be determined based on the position of this edge portion. Furthermore, although the standard size has been described as a full size, it may be a half size.
