Abstract

PURPOSE:To efficiently print a film where full size printing frames and panoramic size printing frames coexist. CONSTITUTION:While the negative film 18 is moved in a 1st direction (forward direction), printing for full size is consecutively performed in a state where printing magnification is fixed at standard magnification and the printing for the panoramic size printing frame is passed. Then, the negative film 18 is moved in a 2nd direction (reverse direction) and the printing for the panoramic size printing frame which has once passed is performed. Therefore, the full size printing frame and the panoramic size printing frame having different enlarging magnification are separately and consecutively printed, and it is unnecessary to frequently perform work such as the driving of a zoom lens 38, the switching of a film mask 26 and the driving of a paper mask 40, thereby improving working efficiency.

Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention relates to a photographic printing method.
More specifically, the present invention relates to a method of printing a film in which full-size print frames and panoramic-size print frames coexist.

0002

2. Description of the Related Art Generally, images taken with a camera are of the same size on a single negative film, but sometimes panoramic images are taken in which the field of view is expanded in the horizontal direction. The size of this panoramic image is such that the vertical direction (the width direction of the negative film), which is a part of one frame, is shortened on the negative film, and the ratio of the horizontal length to the vertical length is 2 It has doubled.

[0003] 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, the conveyance direction of the photographic paper, and the conveyance distance of the photographic paper according to each size. In addition, depending on the situation, changes in photographic paper size, processing conditions, etc.
It is also necessary to change the direction of conveyance of the negative film.

In such a case, depending on whether you are printing a full-size print frame or a panoramic-size print frame, you can either change the printing conditions for each frame and print them one by one, or you can first print a full-size print and then print it again in panoramic size. It is necessary to extract and print only panoramic size print frames using a printer exclusively for printing.

[0005]

[Problems to be Solved by the Invention] However, when printing a film in which full-size print frames and panoramic-size print frames coexist, the above two methods cannot be used.
It is necessary to change the printing conditions such as the printing magnification for each frame. On the other hand, in the method of performing full size printing and panoramic size printing separately, it is necessary to prepare two printers and set the film twice. Furthermore, 2
It takes a lot of effort to compare the prints completed at each location against the negative film to ensure that there are no errors and to ensure that both prints are uniform.

SUMMARY OF THE INVENTION In consideration of the above-mentioned facts, the present invention aims to provide a photographic printing method that can efficiently print a film in which full-size print frames and panoramic-size print frames coexist.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows the configuration of a printing apparatus for carrying out the photographic printing method of this embodiment. First, the mechanical configuration of the printing apparatus will be explained along the optical path.

The printing light emitted from the light source 10 enters the diffusion box 15 after passing through a cyan filter 12A, a magenta filter 12B, and a yellow filter 12C. The amount of insertion of these color filters 12A, 12B, and 12C into the optical path is adjusted by the film adjustment section 14, thereby adjusting the ratio and intensity of the three color components of the printing light. Further, the diffusion box 15 is a rectangular cylinder whose inner surface is a mirror surface, with diffusion plates arranged on both end surfaces, and sufficiently diffuses the color-corrected printing light.

The printing light that has passed through the diffusion box 15 irradiates the negative film 18 on the film carrier 16 placed at the printing position. As shown in FIG. 2, the negative film 18 is a long film in which full-size print frames and panoramic-size print frames coexist. The vertical dimension of the panoramic size print frame is half the vertical dimension of the full size print frame, and the vertical-width ratio is the same as when two full-size print frames are arranged side by side. The negative film 18 is then transported through a pair of feed rollers 20 and 22 disposed at both ends of the negative carrier.
During file size printing, the paper is transported in the forward direction shown by the solid line (toward the right in Figure 1), and while panoramic size printing is performed, it is transported in the reverse direction shown by the dotted line (to the left in Figure 1). . The pair of feed rollers 20 and 22 are interlocked by a chain or the like, and are rotated forward and backward by a pulse motor 24. Further, a film mask 26 is arranged on the negative film 18 to maintain the flatness of the negative film 18. This film mask 26 is provided with a full size hole 26A and a panoramic size hole 26B, which can be switched between them by a motor 27.

A film end detection sensor 28 is arranged on the left side of the film carrier 16 in FIG. 1, and detects the leading and trailing ends of the negative film 18. That is, when the negative film 18 is running forward, the rear end of the negative film 18 is detected, and when the negative film 18 is running backward, the leading edge is detected.

Further, a screen detection device 30 is arranged on the left side of the feed roller 20. The screen detection device 30 is
As shown in Figure 2, multiple (5 in this example)
It is equipped with concentration sensors 32A to 32E. Concentration sensor 32
A to E are arranged in the width direction of the film, and the density sensors 32A and 32E at both ends correspond to the base portion that exists only in the panoramic size print frame.

The printing light transmitted through the negative film 18 passes through the printing zoom lens 38 and reaches the color paper 42 whose exposure range is regulated by a paper mask 40, and transfers the image on the negative film 18 onto the color paper 42. Expose. The zoom lens 38 is driven by a motor 44,
The enlargement magnification during printing can be adjusted. Further, the paper mask 40 is driven by a motor 46 in the longitudinal direction of the color paper 42, and the exposure range is adjusted depending on whether it is full size or panoramic size. The color paper 42 is pulled out from the paper roll 48, passes through a guide roller 49, and reaches a pair of pull-out rollers 51 driven by a pulse motor 50. And paper mask 4
The exposed portion is cut by a cutter 52 placed next to the photosensitive material 0, and is wound up again into a roll to be sent to a photo-developing device (not shown).

A shutter 5 that is opened and closed by a shutter drive section 53 is provided between the zoom lens 38 and the color paper 42.
4 is arranged, and exposure is performed by opening the shutter 54 for a certain period of time.

A scanner 56 consisting of an image sensor and a lens is placed diagonally above the print position, and measures the transmitted light at each point of the frame set at the print position. The output signal of this scanner 56 is supplied to a characteristic value extraction section 57, which will be described later.

Next, the configuration of the control section of the photographic printing apparatus according to this embodiment will be explained. The characteristic value extraction unit 57
Based on the output signal of the scanner 56, characteristic values such as average transmission density and minimum density are extracted for each color for each frame. The exposure calculation unit 58 calculates the exposure using these characteristic values,
This is sent to a controller 61, which will be described later.

The print control section 66 includes the controller 61
Based on the signals from the drivers 65, 67, 68, 69
via pulse motors 50, 44, 46 and motor 27
, and conveys the paper by a predetermined amount, and also drives the zoom lens 38 and paper mask 40 to adjust the printing magnification and masking range.

Based on the input signals from the film end detection sensor 28 and the screen detection device 30, the controller 61
The drive of the pulse motor 24 is controlled via the driver 72. To be more specific, after a print start operation is performed, the motor 24 is first rotated in the forward direction to perform full-size printing, and the negative film 18 is transported forward (rightward) one frame at a time. By counting the drive pulses supplied to the motor 24 with a pulse counter, the moving position of the negative film 18 is detected. In addition, in order to position the frame at the print position, the screen detection device 30
This is performed by counting the number of drive pulses after receiving a signal from the concentration sensors 32A to 32E, and determining whether or not this count value has reached a certain value. Further, in order to perform panoramic size printing, the motor 24 is reversed, the negative film 18 is moved in the opposite direction (to the left), and the frame is positioned at the print position based on the position information of the panoramic size print frame.

The controller 61 controls the printing apparatus in general, and controls the filter adjustment section 14 and shutter drive section 53 based on the signal from the exposure calculation section 58.

Next, the operation of the above embodiment will be explained with reference to FIG. First, when the negative film 18 is loaded onto the film carrier 16 and a print start button (not shown) is pressed, the forward transport of the negative film 18 begins under the control of the controller 61 in step 100. In step 102, it is determined whether or not the end of the film has been reached, and if the determination is negative, the process moves to step 104. At step 104, the density of the frame is detected by the density sensors 32A to 32E, and the screen position and whether it is full size or panoramic size are determined.Then, at step 106, the determination result is stored.

In step 108, it is determined whether or not the frame is a full-size print frame. If the frame is a full-size print frame, the process proceeds to step 110, where the conveyance of the negative film 18 is stopped. If it is determined that the frame is a panoramic size print frame, the process moves to step 102 and conveyance is continued.

Next, in step 112, the printing light emitted from the light source 10 is applied to the color filters 12A, 12B, 12.
C. After passing through the diffusion box 15, the negative film 18 is irradiated. Then, the scanner 56 detects the light that has passed through the frames of the negative film 18 , and the exposure calculation section 58 calculates the exposure amount, which is then sent to the controller 61 .

When the frame set at the print position is a full-size print frame, the controller 61 adjusts the insertion amount of the color filters 12A, 12B, and 12C into the optical path according to the exposure amount. After this adjustment, the shutter 54 is opened for a certain period of time, and the negative film 18 is opened by the zoom lens 38.
The first frame above is printed in full size on color paper 42 (step 114). At this time, the zoom lens 38 is fixed at a standard magnification, and the paper mask 40 is set at a position within the standard range.

Thereafter, as described above, the negative film 18 is moved frame by frame to the right by the drive of the motor 24, and printing is performed only on the full-size print frame, and the panorama-size print frame is passed and the full-size print frame is printed. Print only print frames.

During this full size printing process, when the end detection sensor 28 detects the end of the negative film 18 in step 102, the process moves to step 115, and if there is no panoramic size frame in one negative film, the process is continued. finish. If there is even one panoramic size frame, the process proceeds to step 116, where panoramic size print conditions such as enlargement magnification and paper feed amount are set to conditions corresponding to the panoramic size print frame, and the process proceeds to step 118.

Next, in step 118, the negative film 18 is transported in the opposite direction. In the next step 120, it is determined whether or not the leading edge of the film has been detected. If the determination is negative, the process moves to step 122 and the stored step 1 is returned.
The determination result in step 04 is read out, and in step 124 it is determined whether or not the frame two frames before the printing position is a panoramic size print frame. If it is determined in step 124 that the frame is a panoramic size print frame, the process moves to step 126 and the first panoramic size print frame is set at the print position. Then, in step 128, the exposure amount is calculated,
According to this calculation result, the color filters 12A, 12B, 1
Adjust 2C. Immediately after this, the shutter 54 is opened to perform panoramic size printing (step 130).

Thereafter, by driving the motor 24, frames for panoramic size printing are set one after another at the printing position, and trimming printing is repeated by the same operation, and in step 120, the end detection sensor 28 detects the leading edge of the negative film 18. All printing operations are completed at the time of detection.

In this embodiment, the density sensor 32 determines whether the frame is to be printed in full size or panoramic size.
As shown in FIG. 4, when taking a panoramic image, the negative film 18
A mark 80 may be printed somewhere outside the panoramic image portion, and the presence or absence of this mark 80 may be used to identify whether the frame is a full-size print frame or a panoramic-size print frame. In FIG. 4, the mark 80 may be provided at one or more locations such as a specific position between frames, a normal base portion, and a base portion that exists only in panoramic size print frames.

Furthermore, as shown in FIG. 4, recent negative film 18 has a frame number represented by a barcode 82 printed on the side, so this frame number barcode 82 can be used to set the frame in the print position. The frame number and the panoramic frame may be stored in correspondence with each other, and may be used as frame position information.

Furthermore, as in this embodiment, the scanner 5
6, as shown in FIG. It may be determined whether the frame is a print frame or a panoramic size print frame.

[0039] Furthermore, after the negative film 18 is developed, the operator may visually determine the difference and store it in another storage medium, such as a magnetic memory, together with the frame number. Furthermore, if a signal is given to the beginning or end of one negative film indicating that it is a mixed film of full size print frames and panoramic size print frames, the present invention is applied only to the film with mixed frames by detecting it. However, printing may be performed in only one direction in other cases.

Furthermore, in this embodiment, the negative film 18
When conveying in the forward direction, a full size print frame is printed, and when conveying in the reverse direction, a panoramic size print frame is printed.However, in the reverse direction, a panoramic size print frame is printed, and in the reverse direction, a full size print frame is printed. You may also print a print frame. In addition, in this example, one film was explained as one unit, but 18 negative films were
Work efficiency can be further improved by linking together a roll of long film and transporting it back and forth as a unit, and printing full-size print frames and panoramic-size print frames separately. In this case, it is preferable to connect films requested by the same customer as one roll, which improves the sorting work.

The above is an example of a photo printing printer. The present invention may be applied to a printer processor in which a photographic paper developing machine is combined with a printer. In a printer processor that sends color paper in a direction 90 degrees with respect to the negative film transport direction, a 90 degree rotation in the negative film transport direction is also included in the panoramic size print condition setting. It also includes the ability to switch between two types of photographic paper sizes and change the width of the photographic paper in the processor's photographic paper transport section.Furthermore, two types of lenses are prepared in place of the zoom lens in the above embodiment. You may switch. Further, the screen detection sections 30 may be provided on the left and right sides of the film carrier so that detection can be performed even when the negative film is conveyed in the second direction.

FIG. 3 describes an example in which normal size printing is performed in the first direction, but when printing panoramic size in the first direction, the determination of full size frames in FIG. This can be applied by switching to frames, switching panoramic size frame discrimination to full size frame discrimination, and changing panoramic size print condition settings to full size print condition settings.

Furthermore, the present invention is applicable not only to regular frames and panoramic frames, but also to regular frames and different shooting formats (for example, half size, high-definition size, etc.).

[0044]

Effects of the Invention As explained above, the photographic printing method according to the present invention transports the film in the first direction and the second direction and performs full size printing and panoramic size printing separately in each direction of transport. , there is no need to change the printing conditions for each frame, and one film can be printed continuously, making it possible to efficiently print films that contain a mixture of full-size print frames and panoramic-size print frames. .
