[Operation of image forming system]
Next, document creation/output processing by the image forming system 100 according to the present embodiment will be described based on the flowchart of FIG. 4. In the following example, the image forming system 100 is configured with only one image forming apparatus 10, and all operations related to document creation and output processing, including display and modification operations of composite data, are performed by one image forming apparatus. The example is assumed to be performed in 10.

First, the image forming apparatus 10 uses the acquisition unit 11 to acquire image data including images of the mount D and the certificate C (step S101).
At this time, for example, as shown in FIG. 5, image data including images of the mount D and a plurality of certificates C can be acquired at once. However, if it is not possible to place all the mounts D and certificates C on the acquisition unit 11, or if it is necessary to acquire not only one side of the mount D and certificate C but also the other side, Image data may be obtained by performing an acquisition operation multiple times in succession.

Furthermore, in this embodiment, it is assumed that image data is acquired by reading the mount D and the original paper of the certificate C by the acquisition unit 11 equipped with an optical system, but the method for acquiring image data by the acquisition unit 11 is is not limited to this. That is, an acquisition method in which the control unit 16 functions as the acquisition unit 11 and acquires, for example, image data stored in the storage unit 14, an acquisition method in which the image data DD of a mount that has been uploaded online, etc. Also included.

The control unit 16 that has acquired the image data detects and extracts the mount image data DD and the certificate image data CD from the image data using the detection unit 164 (step S102).

Specifically, for example, if the sizes of various certificates C are registered in advance in the storage unit 14, the detection unit 164 compares the size with the size of the read image data to determine which certificate It is possible to identify which certificate C the image data CD of the certificate is (such as a driver's license or a passport). Further, for example, among the image data, the one that occupies the largest area can be identified as the image data DD of the mount.

Note that the method of extracting and identifying the image data DD of the mount and the image data CD of the certificate by the detection unit 164 is not limited to the above-mentioned method. Other known image detection methods, such as a method for determining, can be employed. Alternatively, a configuration may be adopted in which a plurality of methods are used in a composite manner, weighted, and the determination is made according to the degree of accuracy.

Next, the detection unit 164 detects from the image data DD of the mount an identification image I, which is a symbol that can be read by a QR code (registered trademark) or OCR, and that can detect the pasting part P. Determination is made (step S103). If the identification image I is not detected (step S103; No), the pasting part P is detected from the image data DD of the mount (step S104).
For example, when the detection unit 164 is an OCR and detects a character string such as "certificate", "pasted", "attachment" from the image data DD of the mount, the margin area where the character string is located is the pasted part P. It can be detected that Alternatively, a margin portion having a size larger than a predetermined size in the image data DD of the mount may be detected as the pasting portion P.

When the identification image I is detected (step S103; Yes), the identification image I is read, and from the information included in the identification image I, it is possible to determine from the identification image I to where the pasting part P is. It is identified which certificate's image data CD is to be combined with P (step S105).

The control unit 16 that has detected the pasted portion P in step S104 or step S105 uses the synthesis unit 165 to combine the image data CD of the certificate with the pasted portion P to create composite data (step S106). Note that if the identification image I is detected in step S103, it is preferable to synthesize the image data CD of the certificate so as to overlap the identification image I from above.

The control unit 16 that has created the composite data causes the display output unit 152 to display a confirmation screen (step S107).

FIG. 6 shows an example of the confirmation screen.
The confirmation screen includes, for example, a composite image confirmation section F1 that displays a composite image UD based on the composite data synthesized in step S106, and a certificate data confirmation section F2 that displays a list of the certificate image data CD extracted in step S102. , an add button B1, a modify button B2, a print start button B3, a cancel button B4, and the like.

The control unit 16 determines whether the operation of the print start button B3 has been detected (step S108). When the operation of the print start button B3 is detected (step S108; Yes), the control unit 16 causes the image forming unit 12 to form the composite image UD on the paper, and outputs the document (step S109). The control unit 16 that has output the document ends the document output process.

If the operation of the print start button B3 is not detected (step S108; No), the control unit 16 determines whether the operation of the add button B1 is detected (step S110).
The add button B1 is activated, for example, when there is a certificate C or mount D that the acquisition unit 11 could not read in step S101, or when there is a certificate C or mount D that was forgotten to be read in step S101 (i.e. , when there is mount data DD that is not displayed in the composite image confirmation section F1 or certificate data CD that is not displayed in the certificate data confirmation section F2).

When the operation of the add button B1 is detected (step S110; Yes), the control unit 16 moves to step S101, and similarly extracts the mount image data DD and the certificate image data CD, and extracts the mount image data DD. Detection of the pasted portion P, formation of composite data, etc. are performed, and a confirmation screen is displayed on the display output section 152.

If the operation of the add button B1 is not detected (step S110; No), the control unit 16 determines whether the operation of the modify button B2 is detected (step S111). When the operation of the correction button B2 is detected (step S111; Yes), the screen changes to a correction screen, and the composite data is corrected by operating the operation input section 151 (step S112). On the correction screen, for example, the image data DD of the mount and the image data CD of the certificate can be moved (changed in combination position), rotated (angle corrected), enlarged/reduced, density adjusted, or deleted. When the modification of the composite data is completed, by operating the modification completion button provided on the modification screen, the screen returns to the confirmation screen (step S107).

If the operation of the correction button B2 is not detected (step S112; No), the control unit 16 determines whether the operation of the cancel button B4 is detected (step S113). If the operation of the stop button B4 is detected (step S113; Yes), the control unit 16 stops and ends the document creation/output process.

If no button operation is detected (step S113; No), the control unit 16 waits until any button operation is detected (step S108).

[Effect of the invention]
As described above, the image forming system 100 according to the present embodiment is an image forming system 100 that creates a document in which the image of the certificate C is composited on the pasting part P to which the certificate C is pasted, an acquisition means 11 that acquires image data DD of the document (mount) and image data CD of the certificate, and a detection means 164 that detects the pasting part P from the image data of the document (image data of the mount) DD before composition; It includes a composition means 165 that creates composite data by combining the image data CD of the certificate with the pasting part P of the document D before composition, and an image forming means 12 that forms a composite image UD on paper based on the composite data.
According to this configuration, a document in which images of various certificates C are combined can be created by simply acquiring the image data DD of the document before combination and the image data CD of the certificate using the acquisition means 11. It is easy because it can be done. Further, since only the document in which the image of the certificate C has been synthesized by the image forming means 12 is output, there is no waste.

Further, the acquisition means 11 acquires image data in which the document D and the certificate C are mixed together, and the detection means 164 extracts the image data DD of the document before composition and the certificate from the image data acquired by the acquisition means 11. image data CD is separated.
According to this configuration, there is no need to separate the document D and the certificate C before composition and then acquire the image data using the acquisition means 11, so that the document can be created more easily.

Further, the detection means 164 detects the pasted portion P from the identification image I formed on the document D before composition.
According to this configuration, the pasting part P can be detected more accurately. Further, at this time, if the identification image I includes information on which certificate image data CD should be pasted on the pasting part P, the document can be created with higher accuracy.

The image forming system 100 also includes a display unit 152 that displays a composite image UD based on composite data, and an operation unit 151 that allows the user to modify the composite image UD displayed on the display unit 152.
According to this configuration, the composite image UD formed by the compositing means 165 can be checked in advance before outputting, and if composite data that is different from the expected one is composited, it can be corrected, thereby reducing waste. Able to create documents.

Although the present invention has been specifically explained based on the embodiments described above, the present invention is not limited to the above-described embodiments, and the scope of the invention described in the claims and its scope are Of course, various modifications including equivalence ranges are possible.

[Modified example]
For example, in the above example, the display output section 152 of the image forming apparatus 10 is used as the display means in the image forming system 100, and the operation input section 151 is used as the operation means, but the present invention is not limited to this. That is, the display section 22 of the user terminal 20 may be used as a display means in the image forming system 100, and the operation section 21 may be used as an operation means.

Document creation/output processing in this configuration will be explained based on the ladder chart of FIG. 7.
The image forming apparatus 10 that has acquired the image data in which the mount image data DD and the certificate image data CD are mixed in step S201 transmits the image data to the user terminal 20 under the control of the communication unit 13 by the communication control unit 161. (Step S202).

The following steps S203 to S209 are similar to steps S102 to S108, except that each process is performed by the user terminal 20 (in particular, the control unit 25) instead of the image forming apparatus 10, so a detailed explanation will be given. Omitted. Note that in step S208, a confirmation screen is displayed on the display unit 22.

In step S209, when the operation of the print start button B3 by the operation unit 21 is detected (step S209; Yes), the user terminal 20 transmits the composite image data and the document output signal to the image forming apparatus 10 through the communication unit 23. (Step S210), and causes the image forming apparatus 10 to output a document (Step S211).

Steps S212 to S215 when the operation of the print start button B3 is not detected in step S209 (step S209; No), except that each process is performed by the user terminal 20 instead of the image forming apparatus 10. Since it is the same as steps S110 to S113, the explanation will be omitted. Note that in step S214, a correction screen is displayed on the display section 22, and the composite data is corrected by operating the operation section 21.

According to this configuration, the display means (display output section 152) that displays a composite image UD based on composite data, and the operation means (operation input section 151) that can modify the composite image UD displayed on the display means by user operation. There is no need to provide this in the image forming apparatus 10.

Further, as shown in the configuration, the detection means and the composition means in the image forming system 100 may be realized by the control unit 25 of the user terminal 20 instead of the image forming apparatus 10.

[Other variations]
Further, in general, many certificates C have a unified basic format. Therefore, the detection unit 164 detects the entry fields for name, address, etc. from the image data DD of the mount, and then acquires the information such as the name, address, etc. to be entered in the entry fields from the image data CD of the certificate, and synthesizes the information. It doesn't matter if it is possible to do so.

In this case, when a new certificate C with a unified format is issued, by updating the detection unit 164, it is possible to detect the name, address, etc. from the new certificate C as well. You may also do so. This also applies when the format of the conventional certificate C is revised.

Furthermore, in the above description, it is assumed that the user corrects the composite data in step S112 or step S214, but a correction means that automatically corrects the image data of the mount image data DD and the certificate image data CD is provided in advance. It may also be incorporated into the image forming system 100.

The specific content of the image correction includes, for example, correcting the angles of the image data DD of the mount and the image data CD of the certificate to align their orientations. Another method is to calculate and compare the image size and density of the image data DD of the mount and the image data CD of the certificate, and if there is a difference greater than a predetermined value, perform scaling and density correction. . By providing the image forming system 100 with such a correction means, documents can be created more easily.

Further, the image forming system 100 is provided with a document data creation device that is separate from the image forming device 10 and the user terminal 20 and includes an acquisition device, a detection device, and a synthesizing device and controls the image forming system 100. I don't mind. In this case, the image forming apparatus 10 only needs to include at least an image forming means 12 that outputs the composite image UD as a document.

Further, although the above example has disclosed an example in which a semiconductor non-volatile memory or the like is used as a computer-readable medium for the program according to the present invention, the present invention is not limited to this example. As other computer-readable media, it is possible to apply a portable recording medium such as a CD-ROM. Further, a carrier wave is also applied as a medium for providing data of the program according to the present invention via a communication line.
