Abstract

PURPOSE:To facilitate the accurate collation of a film and a printed photograph thereof by executing the image pickup of printed image data by varying the mounting angle around the optical axis of the image pickup or magnification and making collation again when the film image data and the printed image data do not coincide. CONSTITUTION:The ends of respective orders of the film 10 are first detected by a tape sensor 25 in a printing and exposing section 16 and the top frame is set in a printing position. This image is picked up by a film image pickup section 26. The image of the frame to be printed is printed and exposed by an exposing section 16 to color paper 52. The sort mark of the developed paper 52 is first detected by a mark sensor 50 and simultaneously, the image of the top frame 57 is picked up by a printed image pickup section 53 which binaries and stores this video signal. A controller 31 reads out the film image data and decides whether this data and the printed image data coincide. The image pickup section 53 is rotated by a prescribed angle by an image pickup section rotating mechanism and makes the image pickup again in the case of dissidence. The collation is executed again in accordance with this image data. The image pickup magnification is changed and the collation is executed after the image pickup is made again when the data do not coincide even after this collation.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a photo matching device, and more specifically, a photo matching device that automatically checks whether a film and a printed photo created using the same correspond to each other. Regarding a verification device.

(Prior Art) Conventionally, printed photographs finished with a printer processor are sorted by a device for each order.Furthermore, negative film subjected to printing exposure is cut into film pieces of every 6 frames, and film sheets are This film sheet is then placed on the lighting table,
Each frame is confirmed by the backlight, compared with the image of the finished print, and loaded into a DP bag.

As described above, in the past, since the negative film and the printed photograph were compared manually, there was a problem in that efficient printing operations could not be performed. Furthermore, for verification, a device such as a viewer having a verification table is also required, resulting in an increase in the size of the device.

On the other hand, in Japanese Patent Application Laid-Open No. 61-254946, the present applicant detects the image density of a film image and a photographic paper image, calculates the feature amount of each image from this, and based on this feature amount, both We are proposing a matching device that automatically determines whether images are compatible.

[Problems to be Solved by the Invention] However, since the above-mentioned matching device simply calculates feature amounts from image data and performs matching based on this, the photographic paper may be captured in a bent state when the photographic paper image is captured. ,
There is a problem in that automatic verification becomes difficult when the print magnification changes slightly.

The present invention is intended to solve the above-mentioned problems, and it is an object of the present invention to provide a photo matching device that can accurately match a film and a printed photograph thereof.

1. Means for Solving the Problems: In order to achieve the above object, the present invention provides a means for detecting a joint of a lengthened film, and image data of a frame identified based on the joint detection signal. a film image capturing means for storing the images, a means for recording a sort mark indicating a break for each order on a photosensitive material printed and exposed with an image of the elongated film, and a means for detecting the sort mark after the photosensitive material is developed. and print image capturing means for identifying a frame of the photosensitive material corresponding to the frame identified based on the joint detection signal based on the sorting mark detection signal and capturing an image of this frame, and a magnification and imaging ratio of the print image capturing means. means for changing the mounting angle around the optical axis; and means for comparing the film image data and the print image data, and when the film image and the print image do not match, changing the magnification or the mounting angle of the imaging means and performing the comparison again. It has been established that

In addition, another invention provides that when each image data does not match,
Instead of changing the magnification of the print image capturing means and the mounting angle around the imaging optical axis, either the film image data or the print image data is processed, the magnification or the imaging angle around the optical axis is changed, and the comparison is performed again. This is what I did.

[Operation] When comparing a film and a print photograph created using the film, the film image and the print image are captured by respective imaging means. Then, the film image data and the print image data are compared to see if they match. If these image data do not match, the print image data is captured at different mounting angles or magnifications around the imaging optical axis, and compared again. Furthermore, instead of re-imaging, image data is processed to change the angle or magnification of the film image or print image around the photographing optical axis, and re-verification is performed.

[Embodiments:- Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

As shown in FIG. 2, the photographic machine includes a film loading section 1
3. Paper loading section 14. LSIS-card loading5. Printing exposure section 16. Paper developing section 17, sorter part I 8
．． Film dock section 19 Film cutting inserter section 20. A bagging section 21 is provided. In the film loading section 13, a roll-shaped negative film 10, which is spliced with a splice tape and made into a long length, is loaded for each order. This negative film 10 has been subjected to film development and negative inspection before being sent to a photographic machine. In the negative verification, frames to be printed are specified, printing conditions for these are input as necessary, and these are specified and stored in the LSI card 11 in the order of notches for each order. The LSI card 11 is inserted into the card loading section 15
Otsuko is set.

Further, the printing exposure section 16 is provided with a tape sensor 25 for detecting splice tape, and a film image capturing section 26 for capturing images of frames recorded on a negative film. As shown in FIG. 1, the tape sensor 25 detects the splice tape 27 based on the density difference with the film 10 and sends it to the controller 31.

The controller 31 is composed of a well-known microcomputer, and includes a CPU 32 . ROM33, RAM34
．． Data bus 35. I10 port 36, keyboard 37
It is equipped with a display 38, etc. Then, the number of detected tapes is counted from the splice tape detection signal of the tape sensor 25, and based on this detection order, the LSI cart 1
1 is searched, and the first frame of each order is set at the print position of the film carrier 39 based on the first frame position data of the corresponding order. As the first frame position data, distance data from the splice tape 27 to the first notch 28 is used in this embodiment.
By detecting the maintenance 28 by the maintenance sensor 29,
Perform cents at the print position of the first frame. After this setting, the controller 31 sends a photographing signal to the imaging section 26 and images the first frame.

The imaging unit 26 includes an image area sensor 26a and a lens 26b that forms an image of a frame on the image area sensor 26a, and captures an image of the first frame based on an imaging signal from the controller 31.
This composite video signal is sent to the signal processing circuit 40.

In the signal processing circuit 40, first, the video/synchronization signal separation circuit 4
1 separates the video signal and the synchronization signal, and sends the video signal to the binarization circuit 42. Since the binarization circuit 42 receives a binarization reference signal from the D/A converter 43, the video signal is binarized based on this signal. The serial/parallel conversion circuit 44 converts the binarized serial video signal into a parallel signal based on the synchronization signal. The data launch pulse generation circuit 45 receives the horizontal synchronization pulse signal and field pulse signal from the video/synchronization signal separation circuit 41, and the data bus 35.
A data latch pulse signal is generated by the read signal from . This data launch pulse signal causes the parallel-converted binary signal to be written into a predetermined area in the RAM 34.

At the paper outlet portion of the paper developing section 17, a mark sensor 50, a sensor 51, and a print image capturing section 53 are arranged. The mark sensor 5° is located at the printing exposure section 16.
A cut mark 55 and a sort mark 56 consisting of small holes formed by the punch unit 54 are detected and sent to the controller 31. As is well known, the cut mark 55 is formed on one side edge of the paper 52 in the margin 58 between each frame 57, and the sort mark 56 is formed on the first frame 57 of this order when the splice tape of the film 10 is detected. It is formed on the side edge of the margin section 58 on the opposite side from the cant mark 56. Then, when the mark sensor 50 detects the cut mark 55, the cutter 51 is driven via the driver 51a based on this, and the paper 52 is cut frame by frame.

Further, when the mark sensor 50 detects the sort mark 56, the sorter part 18 is driven based on this, and the sorter part 18 moves by one shelf in each column 18a.

Furthermore, by detecting the sort mark 56, the controller 3
1 controls the print image capturing section 53 to capture an image of the first frame 57 of each order. Like the film image capturing section 26, this imaging section 53 is also composed of an image area sensor and a lens, and sends a composite video signal of the captured image to the signal processing circuit 60. The signal processing circuit 60 is configured similarly to the film image signal processing circuit 40, and records the image data of the first frame in a predetermined area of the RAM 34.

After writing the film image and the corresponding print image in a predetermined area, the controller 31 determines whether or not these image data match. When both image data match, the paper 52 is cut frame by frame, the film 10 is cut into film pieces 63, and inserted into the film sheet 64, and then the bagging section 21 carries out the processing into the corresponding DP bag. Insert into 65.

Furthermore, when the two image data do not match, the print image capturing section 53 is rotated by a predetermined angle θ (5 degrees in this embodiment) by the image capturing section rotating mechanism 70, and the image is captured again. and,
In the same way, import new image data, combine it with the film image data, and if the image data matches,
Start paper cutting. If the image data do not match, the image data is rotated by 2θ in the opposite direction to the previous one, rotated by θ from the origin position to the opposite side, and then new image data is fetched and compared. The imaging unit rotation mechanism 70 rotates the imaging unit 5
3 is rotated by a predetermined angle around the optical axis, and is composed of a drive gear 70a, a motor 70b, and a driver 70c.

If the image data do not match even in the verification after rotating the imaging unit 53, the imaging unit 53 is returned to the origin position, and then the imaging magnification changing mechanism 71
The magnification of the zoom lens 720 of No. 3 is changed and a new verification is performed. The photographing magnification changing mechanism 71 includes a drive gear 71a that changes the focal length of the zoom lens 72, a motor 71b, and a dry huff 1C. Even in this comparison, if there is a mismatch, the imaging unit 53 is rotated forward and backward by a predetermined angle θ to perform re-imaging. In addition to changing the rotation angle and magnification only once as described above, it is also possible to change the amount of change smaller several times (in this case, the merging accuracy can be further improved). The processing procedure described above is shown in FIG.

Next, the operation of this embodiment will be explained. First, as shown in FIG. 2, the roll-shaped film 10 that has undergone negative verification and the LSI card 11 on which the negative verification data thereof is recorded are set in the respective loading sections 13 and 15. The next negative verified film 10a is also set in the empty film loading section 13, and at the same time its LSI card lla is also set in the empty card loading section 15.

The film 10 set in the film loading section 13 is pulled out by a pair of nip rollers 75 and sent to the printing and exposure section 16 via a splicer 76.

In the printing/exposure section 16, the tape sensor 25 first detects the separation of each order of the film IO. The controller 31 sets the first frame at the print position on the film carrier 39 based on this tape detection signal and the distance information from the first order splice tape 27 of the LSI card 11 to the first mince. When the first frame is sent, its image is captured by the film image capturing section 26, and this composite video signal is sent to the second frame via the signal processing circuit 4o.
The splice chain 1 is converted into a value and stored in a predetermined area of the RAM 34.
It is written every 27 detection orders.

The image of the frame to be printed placed at the print position is printed and exposed on the color paper 52 by the printing exposure section 16 based on the print position of the LSI card 11 at an optimum exposure amount. As shown in FIG. 1, the margin 58 of the first frame 57 of the color paper 52 is
A cut mark 55 and a sort mark 56 consisting of small holes are recorded by the punch unit 54 . Further, on the back side of the color paper 52 on which each frame has been printed and exposed, a frame number, order number, etc. are printed by a back print head 80, and a punch unit 54 prints a force mark and an order number in the margin between each frame. 55 is formed. The negative film 10 that has been printed and exposed is sent to a film stock section 19, where it is stored for a predetermined length. Further, the color paper 52 that has been printed and exposed is stored in a loop in the second and third reservoirs 81 and 82 of the paper developing section 17, and then sent to each processing tank and subjected to development processing.

The developed paper 52 is first passed through the mark sensor 50.
When the sort mark 56 is detected, the image of the first frame 57 is captured by the print image capturing section 5.
3, the composite video signal thereof is binarized through the signal processing circuit 60, and stored in a predetermined area of the RAM 34 as address data indicating the order in which the sort marks 56 are detected.

Then, the controller 31 reads out the film image data in the splice tape detection order corresponding to the sort mark detection order, and determines whether or not this matches the print image data. If the image data do not match, as shown in FIG. 3, the print image imaging section 53 is rotated by a predetermined angle by the imaging section rotation mechanism 70 to take another image, and re-verification is performed based on this image data. If the image data do not match even after this verification, the imaging magnification is changed by the imaging magnification changing mechanism 71, and verification is performed after re-imaging. As a result of the comparison, if the image data do not match in any case, the controller 31 issues an alarm and prompts manual comparison.

If the image data match, the controller 31 cuts the paper 52 frame by frame based on the cant mark 55. Further, the film 10 of the corresponding order is sent out from the film stock section 19, cut into film pieces 63 every six frames by the film cutting inserter section 20, and inserted into the film sheet 64. Next, this film sheet 64 is cut out for each order and inserted into the corresponding DP bag 65. After inserting the film sheet 64, this DP bag 65 is set at the printed photo insertion position, and here, the DP bag 65
The sorter part 18 inputs the printed photographs 66 corresponding to one order.

Thereafter, printing processing for each order is performed one after another in the same manner. When the printing exposure of one reel of film 20a is completed, the next film 10a is spliced to the rear end of the reel by a film splicer 76. Furthermore, during this joining, the reading of print information is also switched to that of the next LSI card lla. Further, when the color paper 5252a is pulled out by 10-L, the papers are joined in the same manner as films are joined.

In the above embodiment, when the film image data and the print image data do not match, the print image capturing section 5
3, the imaging angle and magnification around the optical axis are changed, the image is taken again, and the image data is compared again. The magnification may be changed and re-verification may be performed based on this change. That is, as shown in FIG. 4, film image data inputted from the film image capturing section 90 via the signal processing circuit 91, and print image data inputted from the print image capturing section 92 via the signal processing circuit 93. The matching unit 94 determines whether each pixel data matches or not. If they do not match, the image data converting units 95 and 96 rotate or expand/convert the print image data, and the converted image data is The image data and film image data are compared and reverified. In this embodiment, print image data is converted and re-verified, but film image data may be processed in other ways.

In addition, in the above embodiment, the image data of the first frame of each order is compared, but in addition to this, when the comparison of the first frame is insufficient and a matching judgment cannot be made, in addition to this, the image data of the last frame is compared. Image data between frames and other frames may also be compared.

In addition, in the above embodiment, the image data is loaded into the RAM through software control of the access method by the CPU, thereby reducing costs. The image data may be captured by hardware control of the system. In this case, although the cost is high, image data can be captured in real time and the matching processing time can be shortened.

(Effects of the Invention) As explained above, in the present invention, each image data of the film image and the print image is used to compare the film and the print photograph printed and exposed using the same, so that it is possible to use the conventional printer processor. By simply providing an imaging section for film images and print images, and a matching section for image data, automatic matching can be easily performed.Furthermore, when the image data of both do not match, the angle and magnification of the imaging section can be changed. Since the information is changed and the verification is performed again, highly accurate verification can be performed.
