Abstract

PROBLEM TO BE SOLVED: To solve such a problem that one half (first page) of an output prohibition manuscript is output when the information indicating output prohibition about the manuscript has been printed on the right half during continuous shooting of pages.SOLUTION: The image processing apparatus has reading means for reading a manuscript while dividing into N (N is 2 or more) regions and then reading the image data corresponding to each of the N regions. When a code indicating output prohibition is detected from any one of the image data corresponding, respectively, to the N regions read out by the reading means, the remaining data is also not output.

Description

  The present invention relates to an image processing apparatus, a control method thereof, and a program.

  Patent Document 1 discloses a QR code (trademark). In the present specification, a code added to a part of a document such as a QR code is referred to as a “partial code”.

  With the recent increase in information leakage due to duplication of important manuscripts and the like, the above-mentioned QR code is generally used as a measure for preventing unauthorized duplication in the field where security requirements for paper duplication are high. In a generally used method, a duplication prohibition flag is included in the QR code added to the document. When the copying machine reads the copy non-permission flag from the QR code added to the read document, the copying machine determines that copying is not permitted and stops copying. With such a technique, an important document can be prevented from being duplicated by adding a copy non-permission flag to the important document.

Patent Document 2 discloses a function (hereinafter referred to as a page continuous shooting function) that continuously scans the left and right sides of a scan target document placed on a document table and outputs both pages continuously.
The page continuous shooting function can specify whether the document is left-open or right-open. In the case of a left-open document, the left half of the document to be scanned is output as the first document, and then the right half is output as the second document.

JP 10-31447 A JP-A-62-2239

  When a QR code including a copy non-permission flag (an example of information indicating output prohibition) is added to the right half area of the document to be scanned, the left half has no information indicating output prohibition and the right half If there is information indicating output prohibition, the document is a manuscript.

  In the page continuous shooting function, the left and right sides of the scanned document are scanned separately and handled as separate documents. In such a document, the left half of the document is the first and the right half is the second. It will be output as a manuscript.

  For this reason, when information indicating output prohibition regarding the document is printed on the right half, half of the output prohibited document (first sheet) is output.

  In order to solve the above problems, an information processing apparatus according to the present invention is an apparatus having an image reading unit that scans a document by dividing it into N (N is 2 or more) areas and reads N image data. When information indicating output prohibition is obtained from any of the image data read by the image reading means, image data to which the information indicating output prohibition does not belong is not output.

  According to the present invention, it is possible to prevent a part of a document for which copying is prohibited from being output.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  FIG. 1 is a system diagram showing a system applied to Embodiment 1 of the present invention. The configuration of the MFP 100 that is an image processing apparatus in the system of the first embodiment includes a control unit 101, a scanner unit 102, a printing unit 103, a reception unit 104, a display unit 105, a transmission unit 106, a decoder 107, and a storage device 108. The storage device 108 stores the program shown in the flowcharts of FIGS. 4 to 5, and the control unit 101 executes the program to use each of the components 102 to 108 to control the processing of the MFP 100. To control. The scanner unit 102 optically reads a document and generates image data. The scanner unit 102 can read a plurality of originals continuously or can read both sides of the original, and can also read an image by dividing the original into a plurality of areas. An image read by the scanner unit 102 is stored in the storage device 108. The printing unit 103 reads an image from the storage device 108 and performs printing. The printing unit 103 can also perform double-sided printing. A copy function is realized by reading an original with the scanner unit 102 and printing it out to the printing unit 103. The accepting unit 104 can accept an instruction to execute a job such as copying by accepting a key (hard key or soft key) input. Display unit 105 can display job status, alarms, errors, settings of MFP 100, and the like. The transmission unit 106 is connected to the network 109 and transmits the image data read by the scanner unit 102 and stored in the storage device 108 by E-Mail or the like via the network 109 (hereinafter referred to as a transmission function). Used to call). When the control unit 101 detects a QR code that is a two-dimensional code from an image read by the scanner unit 102, the QR code is sent to the decoder 107 and decoded.

In this embodiment, the MFP 100 has a security function that restricts output of images to be output by the printing unit 103 and the transmission unit 106.
A QR code (for example, QR code 111) added to a document (for example, document 110) indicates that a copy permission flag indicating that the document is permitted to be copied, or that the document is forbidden to be copied. The duplication prohibition flag shown is included. The control unit 101 detects a QR code from the image read by the scanner unit 102, and divides the processing depending on whether the QR code has been detected. When a QR code is detected from the read image, the control unit 101 causes the decoder 107 to decode the QR code. As a result of decoding, when a copy permission flag is detected, print output by the printing unit 103 and transmission output by the transmission unit 106 are performed. If the duplication prohibition flag is detected as a result of decoding, the job is canceled. If a QR code is not detected, the job is canceled when the setting in “Restriction without QR code duplication”, which will be described later, is “set”, and when it is not set, print output or transmission output is performed.
In the original 110, a QR code is not added to the left half original left portion 112, and a duplication prohibition QR code 111 is added to the right half original right portion 113.

Next, an operation flow (FIG. 2) in the first embodiment will be described.
In the present embodiment, it is assumed that MFP 100 selects “not set” as “restrict copy without QR code” in the selection of security settings to be described later.
FIG. 2 is a flowchart showing processing when the accepting unit 104 accepts a copy start button press from the user. 2 is realized by the control unit 101 in the MFP 100 executing a program in the storage device 108 to control each component of the MFP 100.

  When the accepting unit 104 accepts pressing of the copy start button, the process is started. In step S201, the control unit 101 determines whether the scan setting of the started job is the page continuous shooting mode. In the page continuous shooting mode, in step S202, the control unit 101 causes the scanning unit 102 to scan the document left portion 112 of the document 110 and reads it as a document image (that is, document image data). Note that the scanning unit may be referred to as a reading unit.

  Next, in step S204, it is determined whether or not the QR code 111 exists in the document image read by the control unit 101 in step S202 (that is, image data obtained corresponding to the left half 112 by the first scan). To do. When it is determined that the QR code 111 does not exist, the process proceeds to step S210, and when it is determined that the QR code 111 exists, the process proceeds to step S206.

In step S206, the control unit 101 controls the decoder 107 to decode the QR code 111. Then, in step S208, the control unit 101 detects whether or not a duplication prohibition flag exists in the digital information in the decoded QR code 111. When the copy prohibition flag (information indicating output prohibition) is detected, the control unit 101 determines job cancellation in step S223, and when the copy prohibition flag is not detected, the process proceeds to step S210.
In step S210, the control unit 101 stores the image scanned in step S202 in the storage device 108 as the first image.

  Next, in step S211, the control unit 101 causes the scanning unit 102 to scan the document right portion 113 of the document 110 and reads it as a document image.

  Next, in step S212, it is determined whether or not the QR code 111 exists in the document image read by the control unit 101 in step S211 (that is, image data corresponding to the right half 113 obtained by the last scan). . When it is determined that the QR code 111 does not exist, the process proceeds to step S214, and when it is determined that the QR code 111 exists, the process proceeds to step S213.

  In step S213, the control unit 101 controls the decoder 107 to decode the QR code 111. Then, in step S214, the control unit 101 detects whether or not a duplication prohibition flag exists in the digital information in the decoded QR code 111. When the duplication prohibition flag is detected, the control unit 101 deletes the document image stored in the storage device 108 in step S210 in step S216. In step S220, the control unit 101 determines job cancellation. If the copy prohibition flag is not detected in step S214, the process proceeds to step S215.

  In step S215, the control unit 101 stores the image scanned in step S211 in the storage device 108 as a second image. In step S217, the control unit 101 outputs the first image and the second image stored in the storage device 108 to the printing unit 103, and prints the first image and the second image. Let

  In step S217, when digital information is obtained by the decoding in S206 and S213 (of course, when the prohibition flag is not detected), the control unit 101 may perform the following processing. That is, the digital information may be encoded to create a new QR code, and replaced with the original QR code. For this process, for example, the original QR code is deleted from the stored image, and the created new QR code is synthesized at the same position. By doing so, the QR code is output in a clean state.

  Note that, when a new QR code is combined with the stored image, it is as follows. That is, a new QR code created from digital information in the QR code obtained by left scanning is synthesized with the left image. On the other hand, a new QR code created from digital information in the QR code obtained by right scanning is synthesized with the right image.

  Further, before the encoding, at least part of the digital information may be maintained and the rest may be changed. For example, if the original QR code includes a user name and permission flag, the user name may be changed to the user name of the user who instructed copying this time while the permission flag remains unchanged. .

  Furthermore, it is conceivable that there is no QR code in S204, there is a QR code in S212, and there is no duplication prohibition flag in S213. In this case, there is no QR code on the left side, and there is a QR code that does not include a copy prohibition flag on the right side. In this case, a new QR code created by encoding digital information in the right QR code (this digital information may be partially changed as described above) is combined with the left image. You may do it. The combined position is the same position as the combined position of the QR code in the right image.

  Of course, the same applies to the case where a QR code exists in S204, the duplication prohibition flag is not detected in S208, and there is no QR code in S212. In this case, there is a QR code that does not include a duplication prohibition flag on the left side, and there is no QR code on the right side. Accordingly, in this case, a new QR code created by encoding digital information in the left QR code (this digital information may be partially changed as described above) is converted into a right image. It can be synthesized into. The combined position is the same position as the combined position of the QR code in the left image.

  If the control unit 101 determines that the page continuous shooting mode is not set in step S201, the control unit 101 scans the entire surface of the document 110 in step S203 and reads it as a document image.

  In step S205, the control unit 101 determines whether the QR code 111 exists in the document image read in step S203. When it is determined that the QR code 111 does not exist, the process proceeds to step S218, and when it is determined that the QR code 111 exists, the process proceeds to step S207.

  In step S207, the control unit 101 controls the decoder 107 to decode the QR code 111. Then, in step S209, the control unit 101 detects whether a copy prohibition flag exists in the digital information in the decoded QR code 111. When the duplication prohibition flag is detected, the control unit 101 determines job cancellation in step S220. When the copy prohibition flag is not detected in step S209, the process proceeds to step S218.

  In step S218, the control unit 101 stores the image scanned in step S203 in the storage device. In step S219, the control unit 101 outputs the image stored in the storage device 108 to the printing unit 103 to print the image.

  In step S219, when the digital information is obtained by the decoding in S207 (of course, when the prohibition flag is not detected), the control unit 101 may perform the following processing. That is, the digital information is encoded to create a QR code, and is replaced with the original QR code (for example, the original QR code is deleted from the stored image and the created QR code is synthesized at the same position). By doing so, the QR code is output in a clean state.

  Further, before the encoding, at least part of the digital information may be maintained and the rest may be changed. For example, if the original QR code includes a user name and permission flag, the user name may be changed to the user name of the user who instructed copying this time while the permission flag remains unchanged. .

A setting screen of MFP 100 will be described with reference to FIG.
FIG. 5 shows a setting screen for carrying out the first or second embodiment. In the screen of FIG. 5, the user can select a security setting. When the user selects “Set” 503 while the “Copy restriction without QR code” 501 is displayed on the display unit 105, the reception unit 104 receives the selection, and the control unit 101 sets the security setting of the MFP 100 to “QR code”. Set to “None replication restriction”. At this time, when the accepting unit 104 accepts pressing of the copy start button from the user, the flowchart of the second embodiment is started. When the user selects “do not set” 502, the MFP 100 operates without the security setting “copy restriction without QR code”. At this time, when the accepting unit 104 accepts pressing of the copy start button from the user, the flowchart of the first embodiment is started.

It should be noted that it is desirable to be able to perform access control such as prohibiting selection on the setting screen of FIG. 5 except for the system administrator.
Here, decoding in the present embodiment will be described. The above-described codes such as the partial code and the entire code are visually represented like a pattern, but both codes are generated by encoding digital information. Decoding in this embodiment refers to processing for extracting the original digital information from the code visually represented as a pattern. The digital information may be text data such as a character string, or binary data represented by an arbitrary bit string. The decoder 107 has a function capable of decoding both partial codes and entire codes.

  In addition, these codes may also be called barcodes, two-dimensional barcodes, digital watermarks, information watermarks, information background patterns, information patterns, and the like.

  As described above, the control unit 101 controls each component of the MFP 100, so that the image output is suppressed even when the document surface to which the copy prohibition flag is added as the QR code 111 is divided and scanned. It is possible to prevent the copying of prohibited originals.

  In the first exemplary embodiment, when “No setting” is selected for “Copy restriction without QR code”, when a document with a QR code including a copy prohibition flag is read by page continuous shooting, the QR code cannot be read. An example is shown in which copying of a manuscript is not permitted even for a certain area. On the other hand, in the present embodiment, when “Copy restriction without QR code” is selected as “Set”, a document with a QR code including a copy permission flag and a document with no QR code added are paged. An example of reading by continuous shooting will be described.

  FIG. 3 is a system diagram showing a system applied to the second embodiment of the present invention. Since the configuration of the MFP 100 is the same between the second embodiment and the first embodiment, only the differences from the first embodiment will be described below.

A copy permission QR code 302 is added to the original 301, and no QR code is added to the original 303. The QR code 302 of this embodiment includes digital information related to the original such as the user name and printing time of the user who printed the original in addition to the duplication permission flag.
The encoder 306 encodes digital information such as a duplication permission flag and a copied user name to generate a QR code image 305.

  Next, an operation flow (FIG. 4) in the second embodiment will be described. The storage device 108 stores a program shown in the flowchart of FIG. 4 is realized when the control unit 101 in the MFP 100 executes a program in the storage device 108 to control each component of the MFP 100. In this embodiment, it is assumed that MFP 100 selects “Set” as “Restriction without QR code duplication” in the selection of security settings in FIG. Also, it is assumed that the user who issued the copy instruction has already been authenticated before pressing the copy start button.

  When the accepting unit 104 accepts pressing of the copy start button, the process is started. In step S401, the control unit 101 determines whether the scan setting of the started job is the page continuous shooting mode. In the page continuous shooting mode, in step S402, the control unit 101 scans the document 301 as the left side of the document and reads it as a document image.

  In step S404, the control unit 101 determines whether the QR code 302 exists in the document image read in step S402. When it is determined that the QR code 302 does not exist, the control unit 101 determines job cancellation in step S426, and when it is determined that the QR code 302 exists, the process proceeds to step S406.

  In step S406, the control unit 101 controls the decoder 107 to decode the QR code 302. In step S408, the control unit 101 detects whether a copy permission flag exists in the digital information in the decoded QR code 302. When the copy permission flag is not detected, the process proceeds to step S426, and when the copy permission flag is detected, the process proceeds to step S410.

  In step S410, the control unit 101 causes the encoder 306 to encode the digital information obtained by decoding in step S406 and generate a QR code 305. Next, in step S411, the control unit 101 combines the image scanned in step S402 with the QR code generated in step S410. Next, in step S412, the control unit 101 stores the image synthesized in step S411 in the storage device 108 as the first image.

  Next, in step S413, the control unit 101 causes the scanning unit 102 to scan the original 303 as the right part of the original and reads it as an original image.

  In step S414, the control unit 101 determines whether the QR code 302 exists in the document image read in step S413. When it is determined that the QR code 302 does not exist, the process proceeds to step S421, and when it is determined that the QR code 302 exists, the process proceeds to step S415.

  In step S415, the control unit 101 controls the decoder 107 to decode the QR code 302. In step S416, the control unit 101 detects whether a copy permission flag exists in the digital information in the decoded QR code 302. If the copy permission flag is not detected in step S416, the process proceeds to step S421. In step S <b> 421, the control unit 101 outputs the first image stored in the storage device 108 to the printing unit 103 to print the first image.

If the copy permission flag is detected in step S416, the process proceeds to step S417.
In step S417, the control unit 101 causes the encoder 306 to encode the digital information obtained by decoding in step S415, and generates a QR code 305. Next, in step S418, the control unit 101 combines the image scanned in step S413 with the QR code generated in step S417. Next, in step S419, the control unit 101 stores the image synthesized in step S418 in the storage device 108 as a second image. In step S420, the control unit 101 outputs the first image and the second image stored in the storage device 108 to the printing unit 103, and prints the first image and the second image. Let

  In step S401, when the control unit 101 determines that the page continuous shooting mode is not set, in step S403, the control unit 101 causes the scanning unit 102 to scan the entire surface including the originals 301 and 303 and read the original image.

  In step S405, the control unit 101 determines whether the QR code 302 exists in the document image read in step S403. When it is determined that the QR code 302 does not exist, the process proceeds to step S426, and when it is determined that the QR code 302 exists, the process proceeds to step S407.

  In step S407, the control unit 101 controls the decoder 107 to decode the QR code 302. Then, in step S409, the control unit 101 detects whether a copy permission flag exists in the digital information in the decoded QR code 302 (in other words, whether a copy prohibition flag does not exist). When the copy permission flag has not been detected (that the copy prohibition flag has been detected), the process proceeds to step S426, and when the copy permission flag has been detected (that the copy prohibition flag has not been detected). Proceeds to step S422.

  In step S422, the control unit 101 changes at least a part of the digital information obtained by decoding in step S407. Then, the digital information after the change is encoded by the encoder 306 and a QR code 305 is generated. At this time, the user name, the printing time, and the like can be changed, and the permission flag remains as it is. Next, in step S423, the control unit 101 combines the image scanned in step S403 with the QR code generated in step S422. Next, in step S424, the control unit 101 stores the image synthesized in step S418 in the storage device. In step S425, the control unit 101 outputs the image stored in the storage device 108 to the printing unit 103 to print the image.

  As described above, when the control unit 101 controls each component of the MFP 100 and “set without QR code duplication restriction” is selected, the document surface is divided as in the page continuous shooting mode. When scanning is performed, it is determined whether copying is prohibited for each scanning. As a result, image output of a document without a QR code is suppressed, so that it is possible to prevent copying of a document that is prohibited from being copied.

  In the first and second embodiments, a process of outputting an image according to the setting of “set” or “not set” of the copy prohibition flag obtained by decoding the detected QR code, the copy permission flag, and “copy restriction without QR code” An example of switching is shown. On the other hand, in the present embodiment, an example in which a document is read by page continuous shooting when “set” is selected in a “QR code creation mode” described later will be described.

  FIG. 6 is a system diagram showing a system applied to the second embodiment of the present invention. Since the configuration of the MFP 100 is the same as that of the second embodiment, only differences from the second embodiment will be described below.

  In the document 601, a QR code is not added to the left half document 603, and a copy permission QR code 602 is added to the right half document 604. The QR code 602 of this embodiment includes digital information related to the original such as the name of the user who printed the original in addition to the duplication permission flag.

  Next, an operation flow (FIG. 7) in the third embodiment will be described. The storage device 108 stores a program shown in the flowchart of FIG. 7 is realized when the control unit 101 in the MFP 100 executes a program in the storage device 108 and controls each component of the MFP 100. In the present exemplary embodiment, it is assumed that “set” is selected in “QR code creation mode” described later in MFP 100. Also, it is assumed that the user who issued the copy instruction has already been authenticated before pressing the copy start button.

When the accepting unit 104 accepts pressing of the copy start button, the process is started. In step S701, the control unit 101 determines whether the scan setting of the started job is the page continuous shooting mode. In the page continuous shooting mode, in step S702, the control unit 101 scans the document left portion 603 and reads it as a document image. If the page continuous shooting mode is not selected, step S712 is performed.
In step S703, the control unit 101 stores the image read in step S702 in the storage device 108 as the first image.

  In step S704, the control unit 101 determines whether the QR code 602 exists in the document image read in step S702. When it is determined that the QR code 602 does not exist, the process proceeds to step S707, and when it is determined that the QR code 602 exists, the process proceeds to step S705.

  In step S705, the control unit 101 controls the decoder 107 to decode the QR code 602. The control unit 101 stores the decoded digital information in the QR code 602 in the storage device 108 in step S706.

  In step S <b> 707, the control unit 101 causes the scanning unit 102 to scan the original right portion 604 and reads it as an original image.

  In step S708, the control unit 101 stores the image read in step S707 in the storage device 108 as a second image.

  In step S709, the control unit 101 determines whether the QR code 602 exists in the document image read in step S707. When it is determined that the QR code 602 does not exist, the process proceeds to step S717, and when it is determined that the QR code 602 exists, the process proceeds to step S710.

In step S710, the control unit 101 controls the decoder 107 to decode the QR code 602. The control unit 101 stores the digital information in the decoded QR code 602 in the storage device 108 in step S711, and the process proceeds to step S717.
In step S712, the control unit 101 causes the scanning unit 102 to scan the document 601 and reads it as a document image.

  Next, in step S713, the control unit 101 stores the image read in step S712 in the storage device 108 as the first image.

  Next, in step S714, the control unit 101 determines whether or not the QR code 602 exists in the document image read in step S712. When it is determined that the QR code 602 does not exist, the process proceeds to step S717, and when it is determined that the QR code 602 exists, the process proceeds to step S715.

  In step S715, the control unit 101 controls the decoder 107 to decode the QR code 602. The control unit 101 stores the decoded digital information in the QR code 602 in the storage device 108 in step S716, and the process proceeds to step S717.

  In step S717, the control unit 101 changes the user name of the digital information stored in the storage device 108 in step S706 or step S711 to the currently logged-in user name, and causes the encoder 306 to encode the QR code 605. Is generated. When there is no digital information stored in the storage device 108, the control unit 101 newly creates digital information using the currently logged-in user name, causes the encoder 306 to encode, and generates a QR code 605.

  Next, in step S718, the control unit 101 combines the first image stored in the storage device 108 with the QR code generated in step S717. Next, in step S719, the control unit 101 outputs the image synthesized in step S717 to the printing unit 103, and causes the first image 606 to be printed.

  Next, in step S720, the control unit 101 checks whether or not the second image is stored in the storage device 108. If the second image is stored, the control unit 101 proceeds to step S718. In step S718, the control unit 101 combines the second image stored in the storage device 108 with the QR code generated in step S717. Next, in step S719, the control unit 101 outputs the image synthesized in step S717 to the printing unit 103, and causes the second image 607 to be printed.

A setting screen of MFP 100 will be described with reference to FIG.
FIG. 8 shows a setting screen for carrying out the third embodiment. In the screen of FIG. 3, the user can select a QR code creation setting. When the user selects “SET” 803 while the “QR code creation mode” 801 is displayed on the display unit 105, the reception unit 104 receives the selection, and the control unit 101 sets the security setting of the MFP 100 to “QR code creation”. Set to "Mode". At this time, when the accepting unit 104 accepts pressing of the copy start button from the user, the flowchart of the third embodiment is started. When the user selects “not set” 802, MFP 100 operates in a state other than “QR code creation mode”. At this time, when the accepting unit 104 accepts pressing of the copy start button from the user, the flowcharts of the first and second embodiments are started.

  It should be noted that it is desirable to be able to perform access control such as prohibition of selection on the setting screen of FIG. 8 except for the system administrator.

  As described above, the control unit 101 controls each configuration of the MFP 100. The case where “setting” is selected as the “QR code creation mode” and the document surface is divided and scanned as in the page continuous shooting mode has been described above as an example. Even in such a case, it is possible to obtain the effect that the digital information of the QR code added to the document can be succeeded to the duplicate image in the area where the QR code is not detected.
