DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photographic print system, and more particularly to a photographic print system for automatically creating an index photograph for each case.

[0002]

2. Description of the Related Art In order to easily know what kind of pictures are contained in one negative film, index pictures in which each frame is arranged in a matrix and reduced and printed are known (for example, JP-A-61-12
2639). When creating this index photograph, the film pieces obtained by dividing one negative film on the stage are arranged in the same arrangement as that inserted into the film sheath, and this is pressed with a mask,
Illumination is applied from the back of the film piece and printed on photographic paper through a reduction lens system.

In addition, the applicant of the present invention has proposed a photographic printer which can perform an enlarged print of each frame and an index print with the same photographic printer without using a device for printing an index photograph separately from the photographic printer. This is proposed in JP-A-64-80940.
In this photo printer, a first mirror is inserted between a film deck and a printing lens, an image of each frame of the photo film is captured by a television camera, and these images are fitted and synthesized to create an index image. The image is displayed on a CRT and printed on a photosensitive material via a second mirror.

In large-scale developing laboratories, about 50 to 100 photographic films are connected and lengthened for efficient photographic processing. After loading this long film into the film processor and developing it,
Set in a puncher and perform a film test. In this notch / puncher, frame detection is automatically performed, and each frame is sequentially set at a verification position. By observing the frame set at this verification position, it is determined whether or not to print a photograph.
If it is determined that the image should be printed, a semicircular notch is formed at the film side edge passing through the center line of the frame.

Next, a long film is loaded into a film analyzer (also called a scanner), and each frame is sequentially set at a photometry position. An image sensor is arranged at the photometry position, and measures the transmission density of each point of the frame. Using the transmission density of each point, the minimum density, maximum density,
Average transmission density at the center of the screen, average transmission density at the periphery of the screen,
The average transmission density of the upper half of the screen, the average transmission density of the lower half of the screen, and the like are obtained, and the frame is classified into scenes using these characteristic values. The exposure correction amount is calculated according to the scene classification.
This exposure correction amount is written in a storage medium such as a paper tape, a magnetic tape, and an LSI card.

[0006] A long film that has passed through a film analyzer and a storage medium are loaded into an auto printer. In this automatic printer, each frame of a long film is automatically set in sequence at a printing position, and then the average transmission density (hereinafter referred to as LATD) of the entire screen is measured. Obtained LAT
The printing exposure time is calculated from D and the exposure correction amount read from the storage medium. During this printing exposure time, the frames are printed and exposed on photographic paper. When the printing of all the frames of the long film is completed, the photographic paper is developed by a paper processor, and then cut one by one by a cutter. Since a long photographic film is used by connecting a large number of negative films in this way, it is possible to print and expose each photographic film at high speed and efficiently.

[0007]

However, when an index photograph is to be created by such an auto printer, the printing is performed by a CRT or a laser printer, so that the printing time of each frame is longer than that of other frames. Further, when the same exposure stage is used, it is necessary to switch the mirror, which takes time. Therefore, there is a problem that the high-speed processing performance of the above-described auto printer is reduced. Also, in the case of a printer processor for a small-scale developing laboratory, there is a problem that the processing capacity is similarly reduced.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a photographic print system capable of creating index photographs without deteriorating the high-speed processing performance of photographic prints. Another object of the present invention is to provide a photographic print system in which a print photograph and an index photograph thereof are formed in the same case so that collation can be easily performed.

[0009]

According to a first aspect of the present invention, there is provided a photographic print system provided in a film analyzer for reading an image of each frame recorded on the photographic film. An index image creation unit that creates an index image for each case based on image data from the imaging unit; an index image storage unit that stores index image data from the index image creation unit; A photosensitive material transport unit that provides an index print area between print images for each case;
Before the sort mark to distinguish print images for each job
A sort mark forming means for forming on the photosensitive material; a photographic printer provided with the sort mark;
Identify the dex print area and use this index
An index image based on the index image data from the index image storage unit for the lint area
An index print section for printing and exposure, and a photosensitive material buffer section provided between the photographic print section and the index print section for storing a belt-shaped photosensitive material are provided.

Another photographic print system of the present invention records index image data in a storage medium such as an LSI card and prints and exposes the index image on a photosensitive material using the index image data. Further, another photographic print system of the present invention includes :
The index image is synthesized after performing the density and color correction based on the exposure correction amount of each frame. Further, other photographic printing systems of the present invention
There are multiple formats for
Combine index images based on format
It is composed.

[0011]

According to the present invention, each frame of a photographic film is measured by a film analyzer, and an exposure correction amount is calculated based on the measured light. This exposure correction amount is written to the LSI card. At the time of this photometry, image data of each frame is taken in, and an index image is created based on the image data. The index image data is temporarily stored in a recording medium such as an image buffer or an LSI card. In a photographic printer, each frame of a photographic film is printed and exposed on a photosensitive material by a photographic print unit. An area for recording an index image is skipped between each case, and an index print area is formed. An index image is printed and printed on the index print area by the index print section. The processing speed in the index printing unit is lower than that in the photographic printing unit, and the photosensitive material is temporarily stored in a loop in the photosensitive material buffer unit so as to absorb this difference in processing speed. Since index printing is performed during the printing time of a normal photo film, the processing capability of the photo printer is not reduced.

DESCRIPTION OF THE PREFERRED EMBODIMENTS As is well known, a long film 10 is developed by a film processor and then subjected to a film inspection by a notch / puncher. In this film test,
The determination as to whether or not to print a photo and the formation of a notch are performed. The notch indicates that a photo print is to be performed, and indicates the center line of the frame.

As shown in FIG. 2, a long film 10 subjected to a film test is set on a film analyzer 11. The long film 10 is pulled out from the supply reel 13 one by one by a film feed roller pair 12. Then, based on the notch detection signal from the notch sensor 14, the controller 15 stops the film feed motor 16 after rotating the film feed motor 16 via the driver 16a, thereby automatically setting the notched frame at the pre-photometry position 17. I do. A white light source 18 and a mixing box 19 are arranged above the pre-metering position 17, and a film mask 20 for masking the periphery of the frame is arranged below the pre-metering position 17. The frame measured at the pre-metering position 17 is taken up on a take-up reel 21.

The controller 15 is composed of a known microcomputer, and includes a keyboard 22, a display 23, and a memory 24. Controller 15
Is the notch sensor 14
The number of notches for each case is counted based on the signal from the controller, and this count value is stored in the memory 24 for each case as print frame number data.

The lens 25 forms an image of the frame set at the pre-metering position 17 on the imaging surface of the color image sensor 26. The color image sensor 26 includes a plurality of pixels arranged in a matrix, and a mosaic filter arranged thereon. The mosaic filter divides the pixels into red pixels, green pixels, and blue pixels. One measurement point (one pixel) is measured by 3 × 3 pixels in the matrix arranged alternately. When measuring one measurement point,
By adding and reading the signal charges of three pixels of the same color, three primary color separation photometry is performed in a pseudo manner.

The color image sensor 26 sends three color signals of red, green and blue at each point to the arithmetic unit 27. The arithmetic unit 27 calculates the transmission density of each point (strictly, a value proportional to the transmission density) for each color by logarithmically converting the signal. Further, the arithmetic unit 27 calculates an average value (gray density) of the three color densities of each point, and calculates characteristic values such as a minimum density, a maximum density, and an average transmission density in a predetermined area.
This area includes, for example, the entire screen, the upper half, the lower half, the center of the screen, the periphery of the screen, the left half of the screen, the right half of the screen, and the like.

The operation unit 27 classifies scenes from these characteristic values, and calculates L by using an operation expression prepared for each scene.
The exposure correction amount for ATD is calculated for each color. These exposure correction amounts are written to an LSI card 29 by an LSI card writer 28.

Further, at a position facing the film mask 20,
An imaging unit 32 including a lens 30 and a color image sensor 31 is provided, and the imaging unit 32 captures each image data of a frame to be printed. The captured image data is sent to the index image creation unit 35. Instead of using the imaging unit 32 and the photometry unit individually, the image of the frame to be printed may be captured using the color image sensor 26 of the photometry unit. Further, the optical path may be branched by a beam splitter or the like, and the image data and the exposure correction data may be obtained by the imaging unit 32 and the photometry unit.

The index image creating section 35 creates an index image from the three-color image data of each frame based on a format stored in the memory 36 (see FIG. 5) in advance. 3 and 4 show examples of various formats of the index image. 3A shows a format F1 for a 12-shot film, FIG. 3B shows a format F2 for a 24-shot film, and FIG. 3C shows a format F3 for a 36-shot film. These formats F1 to F
Reference numeral 3 denotes a basic format determined so that the subframe 37 can be large. FIG. 3D shows a format F4 for displaying 16 frames.
In the case of multi-shot film, this is used for one frame,
Four frames are used for two frames, and 36 frames are used for three frames. FIG. 4E shows a format F5 for taking 12 images in which index images are grouped in film piece units.
It is. Similarly, (F) shows a format F24 for taking 24 pictures displayed in film piece units, and (G) shows a format F7 for taking 36 pictures displayed in film piece units.
It is. A frame number 38 is image-combined on the right shoulder of each sub-frame 37. Further, the title images 39 are inserted in the formats F5 to F7.
Note that these formats F1 to F7 are examples, and the number of subframes, their reduction ratio, arrangement, and the like can be changed as appropriate. Further, in addition to the title image 39, exposure correction data and the like may be recorded. Also, the print size of the index image is 2 L in addition to the normal size, for example, L size.
It may be printed in a size, a panorama size, or the like.

As shown in FIG. 5, various formats F1
To F7 are selected by the format selection unit 40.
The format selection unit 40 receives the format designation signal input from the keyboard 22 (see FIG. 2) and the memory 2
The above formats F1 to F7 are selected based on the print frame number data for each case from No. 4. First, basic formats F1 to F3, unified format F4, title-containing formats F5 to F
7 is designated from the keyboard 22. And the memory 24
The format corresponding to the film length is automatically selected based on the print frame number data for each case.

The image processing section 41 performs image processing such as color correction, gradation correction and size conversion on the image data of each frame based on the selected format to create an index image. At this time, as shown in FIGS. 3 and 4, the frame number 38 is also synthesized with the frame number 38 on the right shoulder of the sub-frame 37 of the index image based on the frame number data of each frame. The frame number data is stored in the long film 1 as is well known.
The frame number is input by reading the frame number bar code formed on the side edge of 0. The index image data is sent to the image buffer 45 by the data transfer unit 42 for each case.

The image buffer 45 is composed of a large-capacity memory device. After the data is converted into three-color image data by the data conversion unit 46, the data is stored in the three-color frame memories 45a, 45b, and 45c by the memory controller 47. Is written. Image buffer 4
Reference numeral 5 has a capacity for temporarily storing index images of the long film 10 for several rolls. The image buffer 45 is connected to the auto printer 50, and sends index image data for each case to the auto printer 50 by the data transfer unit 48. As described above, since the index image is created based on the image data of each case and stored, the number of storage cases in the image buffer 45 can be increased as compared with the case where each image of each case is stored individually. .

As shown in FIG. 1, a film analyzer 1
1 and the long film 10 which has been pre-metered by
The I card 29 is set in an auto printer 50 of a white color reduction method. In the auto printer 50, the long film 10 is pulled out from the supply reel 52, and each frame is set at a print position 53 by detecting a notch. A film carrier 54 is disposed at the print position 53. The film carrier 55 and the film pressure plate 56 allow the film pressure plate 5 to be used during main photometry and photo printing.
6 is driven by a solenoid to press the periphery of the frame to be photo-printed against the film mask 55.

The color paper 60 is set on a take-up shaft 61 in the form of a roll, and is sent to an exposure stage 64 for photographic printing and an exposure stage 65 for index printing by a pair of conveying rollers 62 and 63. As is well known, the exposure stages 64 and 65 are provided with paper pressure plates 64a and 65a and easel masks 64b and 65b, respectively.

A puncher 66 is provided on the paper exit side of the exposure stage 64 for photographic printing. As shown in FIG. 6, the puncher 66 forms a cut mark 69 composed of a small hole and a sort mark 70 in a margin between the print frame 67 and the index frame 68 of the color paper 60. The cut mark 69 is formed between the frames 67 and 68. The mark 69 is detected by the automatic paper cutter, and the color paper 60 is cut based on the cut mark 69 and cut into each print photograph. The sort mark 70 is formed on the opposite side to the side on which the cut mark 69 is formed to separate each case, and the printed photographs are sorted by one order based on this.

As shown in FIG. 1, a sort mark sensor 71 is provided on the upstream side of the index print exposure stage 65 on the paper. The area IPA (see FIG. 6) is positioned on the exposure stage 65 for index printing.

A paper buffer 72 is provided between each of the exposure stages 64 and 65 to absorb a difference in printing exposure processing speed between the exposure stages 64 and 65. The paper buffer 72 is provided for each of the exposure stages 6.
The free loop 73 is formed by the difference in the paper feed speeds of 4,65. In this embodiment, the photo print unit 75
Is 300 msec, and the print cycle in the index print unit 76 is 3
c. Therefore, as shown in FIG. 6, the normal print frame 67 is printed and exposed for 10 frames while the index frame 68 is printed and exposed for one frame. Is formed in the paper buffer 72.

A cut filter unit 82 and a mixing box 83 are arranged in a printing optical path 81 connecting the white light source 80 and the print position 53 of the photo print unit 75. The cut filter unit 82 includes a blue cut filter 82a for blocking transmission of blue light, a green cut filter 82b for blocking transmission of green light, and a red cut filter 82c for blocking transmission of red light. When the exposure of the corresponding color is completed, the printing optical path 81
Is inserted into.

The frame set at the print position is sent to a light measuring section 85 comprising a lens 85a and a light measuring sensor 85b.
The ATD is measured for each color and sent to the calculation unit 86. The calculation unit 86 calculates the exposure time of each color using the following formula, based on the LATD of each color and the exposure correction amount of each color read from the LSI card 29.

[0030]

## EQU1 ## Ti = TNi × 10 ^(Di-DNi) × 10 ^DAi

Here, each symbol is as follows. i: Represents any one of blue, green, and red Ti: Printing exposure time of a frame to be photographic printed TNi: Printing exposure time of a normal control negative Di: LATD of frame to be photographic printed DNi: Transmission of a normal control negative Density DAi: Exposure correction amount

The frame set at the print position is printed on the color paper 60 through the printing lens 88 under the calculated exposure time Ti for each color. After the printing exposure, the color paper 60 is fed by one frame. Below the printing lens 88, a black shutter 89 for starting exposure is arranged.

The controller 90 includes a photo print unit 75
And an index print unit 76. Further, the controller 90 reads the exposure correction amount and the number of print frames for each case from the LSI card 29 by the LSI card reader 91.

The index print section 76 has an index image display section 92. The index image display unit 92 drives the color CRT 94 via the driver 93 and displays an index image on the color CRT 94. This display image is formed on the color paper 60 on the exposure stage 65 for index printing via the printing lens 95, and the index image is printed and exposed. These index image display section 92, driver 93, color C
The index print unit 76 is constituted by the RT 94, the printing lens 95, and the like. Reference numeral 96 denotes a black shutter, 97 denotes a paper splicer for joining color paper, 98 denotes a cutter, and 99 denotes a winding shaft.

Next, the operation of the above embodiment will be described with reference to the flowcharts shown in FIGS. As shown in FIG. 2, the long film 10 after the development processing is pre-metered by a film analyzer 11, and an exposure correction amount DAi is calculated from various characteristic values based on the metered value. The number of frames to be printed is obtained for each case.
Then, the exposure correction amount is written to the LSI card 29 by the LSI card writer 28.

As shown in FIG. 2, an image of a frame to be printed is picked up by the image pick-up unit 32 during pre-metering, and sent to the index image creating unit 35. The index image creation unit 35 automatically selects a format of the index image that matches the number of print frames, based on the print frame number data for each case. For example, in the case of a 12-shot film, the format F1 of FIG.
In the case of a single-shot film, the format F shown in FIG.
2 is a 36-frame film, the format F3 in FIG. 3C is selected, and the image of each frame is synthesized at the corresponding frame number position based on the selected format. Further, when title characters such as “graduation ceremony”, “travel Mt. Fuji”, and “wedding” are input at the time of the film test, as shown in FIGS. The title image 39 is fitted. The title image 39 may be ordered when the film is received, or may be photographed using a magnetic recording type photo film or photographed with a magnetic recording camera, or may be photographed on a camera LSI card using a normal photo film. When these are recorded, they are read at the time of a film test or by a film analyzer.

When a format in which the sub-frames of the index photograph are always the same size regardless of the number of photographed films is selected, an index image is created based on the format F4 in FIG. 3D. In this case, when the subframe of the first index picture is full, the image of each frame is combined with the subframe of the next second index picture. When a plurality of index photos are created, the number of index photos is calculated in advance based on the number of print frames data for each case, and based on this number data, the photo print unit 75 prints each frame for each case. After the exposure, the number of frames of the index photograph is skipped, and an index print area IPA is formed between each image.

The index image data for each case is sent to the image buffer 45, where the index image data for several rolls of the long film 10 is temporarily stored.

The long film 10 and the LSI card 29 for which the pre-photometry by the film analyzer 11 has been completed are
Is set in the auto printer 50 as shown in FIG. The long film 10 is pulled out one frame at a time and set at the print position 53.

When the frame to be printed is set at the printing position, the long film 10 and the color paper 60 are pressed against the printing surface and the exposure surface by the film pressure plate 56 and the paper pressure plate 64b, respectively. Is started, and the LATD of red, green, and blue is calculated. Using the LATD of the three colors and the exposure correction amounts of the three colors, the printing exposure time Ti of the three colors is calculated from the above-described equation.

After calculating the printing exposure time, the controller 9
In the case of 0, the black shutter 89 is retracted from the printing optical path 81, and the frame set at the print position is projected on the color paper 60. When the blue exposure time elapses, for example, the controller 90 sets the blue cut filter 82a.
Is inserted into the printing optical path 81 to complete the exposure of the blue light. Thus, the three types of cut filters 82a-
When all of 82c is inserted into the printing optical path 81, the black shutter 89 is closed.

When the black shutter 89 is closed, the cut filter unit 82 operates and the cut filter 82
a to 82c are retracted from the printing optical path 81. The long film 10 and the color paper 60 are transported again, and the printing of the next frame is started. This color paper 6
After the frame advance of 0, a cut mark 69 (see FIG. 6) is formed by the puncher 66 in the margin between the frames. When the printing exposure of each print frame 67 for one case is completed, after the cut mark 69 is formed, the color paper 60 for the index photograph is fed in an idle manner, and the index print area IPA is formed between each case. You.
This blank feed is one frame when the index photo is made the same size as the other print photos. Also, when creating index photos at panorama size,
Two frames are skipped. In the case where the index photograph is divided into a plurality of prints and printed, the required number of prints are fed by the required number. After this idle feeding, a puncher 66 forms a sort mark 70 indicating a break for each case. In the same manner, the next item is printed and exposed in the photographic print unit 75 in the same manner.

The index print section 76 positions the index print area IPA on the index print exposure stage 65 by quantitatively feeding the color paper 60 after the sort mark sensor 71 detects the sort mark 70. After this, color CRT
When the index image is displayed at 94, the image is formed on the photosensitive emulsion surface of the color paper 60 via the printing lens 95, and printing printing of the index photograph is performed. After the print exposure of the index photograph, the color paper 60 which has been subjected to the print exposure is wound around a winding shaft 99.

The printed and exposed color paper 60 is taken out of the auto printer 50, developed by a paper processor, cut into individual frames by an auto paper cutter, and accumulated for each case. The photographic film subjected to the printing exposure is cut into film pieces every six frames by a cutting inserter, and inserted into a film sheath for each case. Thereafter, the film piece inserted into the film sheath is collated with the print photograph including the index photograph, and the print is verified, and the DP bag is packed.

In the above embodiment, as shown in FIG. 2, the index image buffer 45 is provided between the film analyzer 11 and the auto printer 50. However, instead of this, the index image buffer 45 is provided for each frame from the film analyzer. An image buffer in which image data is simply stored for each case may be provided. Then, an index image may be created based on the image data by the index print unit of the auto printer. Although the index image creation unit 35 is provided in the film analyzer 11, it may be provided on the image buffer 45 side. Further, the index image synthesizing section 35 and the image buffer 45 may be provided on the auto printer 50 side. Further, image data of each frame may be taken in by a scanner provided separately from the film analyzer.

Although the exposure correction amount from the film analyzer 11 is written in the LSI card, the exposure correction amount may be sent online to the auto printer similarly to the index image.

Further, when the image data is combined with the sub-frames by the index image creating section 35, color correction and density correction are performed using the exposure correction amount from the pre-metering section, so that the The image can be printed by exposure at an appropriate exposure amount, and the print quality of the index photograph can be improved.

Further, when creating an index photograph, the same cutting position determination as in the film cutting process in the film cutting inserter is performed to determine the cutting position of the long film, and based on this, the image of each frame is determined for each film piece. They may be grouped. In this case, since the sub-frames of the index photograph are grouped in the same manner as the film pieces, it is easy to specify the frame to be printed at the time of additional printing. Then, the cutting position is recorded on an LSI card, and is set in a film cutting inserter, whereby each film piece can be cut at the same position as the index photograph. In the case of a film cutting inserter using the same film cut position determination program, the writing of the cutting position on the LSI card can be omitted.

In the above embodiment, the index image is displayed on a color CRT and printed on color paper.
The index image may be printed and exposed by sequentially exposing three color planes using a monochrome CRT and three color filters. Further, the index image may be printed and exposed by scanning the color paper in the width direction with a laser beam and feeding the color paper in synchronization with the scanning. Further, three-color plane exposure may be performed sequentially using a liquid crystal panel, or scanning exposure may be performed using a line type liquid crystal display.

Further, in the above embodiment, the index photograph was recorded after the printing exposure of each frame in the same case. However, in addition to the above, the top of each frame in the same case is located at an appropriate position in the same case. May be recorded.

Next, an embodiment in which the length of an index image is adjusted according to the number of recording frames for one case will be described.
In this case, the format shown in FIG. 10 is used. FIG. 10 (H) shows a format of 12 shots,
(J) is a format for taking 24 pictures. Even if the number of recording frames is different, the same size is used for each sub-frame. Therefore, as the number of recording frames increases, the length of an index photograph is almost two in 24 shots compared to the case of 12 shots. Although it is not shown in the figure, the length is almost tripled for 36 shots. Note that the format shown in FIG. 10 is an example, and these layouts can be changed as appropriate. Also, in the format shown in FIG. 10, the frames may be grouped in units of film pieces. In this case, each frame can be easily specified when ordering additional prints.

When the format shown in FIG. 10 is used, the idle feed amount in the photo print unit 75 shown in FIG. 1 is set to a length corresponding to the number of recording frames. Then, the index print unit 76 adjusts the opening amount of the paper mask 65a according to the length of the index print. In addition, by scanning the color paper in the width direction with the laser light and sending the color paper in synchronism with this while printing and exposing the index image, and by scanning and exposing using a line type liquid crystal display, this is performed. Index photographs having different lengths can be easily created. In this case, it is not necessary to change the aperture of the paper mask as described above.

In the above embodiment, the image buffer 45
The index image data is sent to the auto printer via the LSI card writer 28. In addition, as shown in FIG. 33 may be written. The same components as those in the embodiment shown in FIG. 2 are denoted by the same reference numerals. In this case, as shown in FIG. 1, an index LSI card 33 is set in the LSI card reader 91 in place of the exposure correction LSI card 29, and the LSI card reader 91 uses the LSI card 33.
, The index image data is read out, and the index image is printed and exposed on the color paper 60 by the index print unit 76 based on the index image data. Thus, LSI
By sending the index image data to the auto printer using the card 33, the LSI card 2 for the exposure correction amount is sent.
In addition to being able to input index image data with the same operational feeling as in No. 9, there is no need to use the image buffer 45, and the configuration can be simplified. In addition, by taking an image of a frame to be printed using the color image sensor 26 for photometry, one image sensor can be used as well, and the configuration can be simplified. In addition,
The recording medium is not limited to an LSI card,
Another recording medium such as a floppy disk or an optical disk may be used.
