  The image processing apparatus 100 according to the present embodiment has a function of converting data indicated by character information into two-dimensional code information. Here, as the two-dimensional code information, various information generally known as two-dimensional code information can be used. For example, a QR code can be used.

FIG. 1 is a block diagram illustrating a configuration of an image processing apparatus 100 according to the present embodiment.
The image processing apparatus 100 includes a document data acquisition unit 102, a list table generation processing unit (list table generation unit) 104, a detection unit 106, a partial image data generation unit 108, a decoding unit 110, an instruction reception unit 112, a print processing unit 114, A write processing unit 116 and a setting storage unit 118 are included.

  In the present embodiment, the image processing apparatus 100 can be configured to have a facsimile communication function. The image processing apparatus 100 can be, for example, a network multifunction machine that integrates a facsimile, a printer, a copy, a scanner function, and the like. Hereinafter, a case where the image processing apparatus 100 is a network multifunction device will be described as an example. Here, the network multifunction peripheral is, for example, a network facsimile apparatus or an MFP (Multi Functional Peripheral).

  Each component of the image processing apparatus 100 is centered on an arbitrary computer CPU, memory, a program that realizes the components shown in the figure loaded in the memory, a storage unit such as a hard disk for storing the program, and a network connection interface. It is realized by any combination of hardware and software. It will be understood by those skilled in the art that there are various modifications to the implementation method and apparatus. Each drawing described in the embodiment shows a block of functional units, not a configuration of hardware units. In FIG. 1, the configuration of parts not related to the essence of the present invention is omitted.

  The network 150 is a public network such as the Internet, a local network such as a LAN, and a PSTN (Public Switched Telephone Network). Here, it is shown as one network for simplification.

  The document data acquisition unit 102 acquires document data. The document data acquisition unit 102 may be, for example, document data read by a scanner function, or may be facsimile data transmitted from another terminal via the network 150.

  The list table generation processing unit 104 (list table generation unit) controls list table generation processing for managing two-dimensional code information included in the document data acquired by the document data acquisition unit 102. First, when the document data acquisition unit 102 acquires document data, the list table generation processing unit 104 determines whether to perform list table generation processing.

  The instruction receiving unit 112 receives a list generation instruction from the user. The list generation processing unit 104 determines that the list generation processing is to be performed when there is a list generation instruction from the user via the instruction receiving unit 112.

  The setting storage unit 118 stores settings such as whether to perform a list generation process and whether to print the generated list. The list generation processing unit 104 can determine that the list generation processing is to be performed when it is set to perform the list generation processing with reference to the setting storage unit 118.

  When the list generation processing unit 104 determines that the list generation processing is to be performed, the detection unit 106 determines whether or not the original data acquired by the original data acquisition unit 102 includes two-dimensional code information in a predetermined format. To detect.

  When the two-dimensional code information is detected by the detection unit 106, the partial image data generation unit 108 extracts the two-dimensional code information from the document data and generates partial image data. In the present embodiment, the partial image data generation unit 108 generates, as partial image data, two-dimensional code information and a partial extracted region around the two-dimensional code information.

  When the detection unit 106 detects two-dimensional code information, the decoding unit 110 decodes the two-dimensional code information into character information.

  The list generation processing unit 104 generates a list of correspondence data in which the partial image data generated by the partial image data generation unit 108 and the character information decoded by the decoding unit 110 are associated with each other. Further, when the document data acquisition unit 102 acquires a plurality of document data through a series of processes, the list table generation processing unit 104 generates a list by collecting corresponding data generated from the plurality of document data. For example, when the document data acquisition unit 102 acquires a plurality of facsimile documents by one communication, the list generation processing unit 104 generates a list by collecting corresponding data generated from these document data.

  When a plurality of two-dimensional code information is included in one page of document data, the list generation processing unit 104 generates corresponding data for each, and information indicating that these are included in the same page of document data Can be added to generate a list.

  The list generation processing unit 104 stores the generated list in the writing processing unit 116. Also, the list generation processing unit 104 refers to the setting storage unit 118 and causes the print processing unit 114 to print the list table when the setting storage unit 118 is set to print the list table. The user can also instruct whether to print the list through the instruction receiving unit 112. When there is a print instruction from the user via the instruction receiving unit 112, the list generation processing unit 104 causes the print processing unit 114 to print the generated list.

FIG. 2 is a diagram illustrating an example of a list generated by the list generation processing unit 104.
FIG. 2A shows a series of data when the document data acquisition unit 102 acquires a plurality of document data through a series of processes. Here, for example, one first two-dimensional code information 302 is included in the first page 300. The fifth page 304 includes two pieces of two-dimensional code information 306 and 308. Here, the partial image data generation unit 108 generates partial image data (302a, 306a, 308a) by partially extracting the two-dimensional code information and a predetermined area around it.

  In such a case, the list generation processing unit 104 generates a list of corresponding data in which each page number, partial image data, and character information generated by the decoding unit 110 are associated (FIG. 2B). ). When a plurality of two-dimensional code information is included in one page, for example, settings such as describing the two-dimensional code information on the page at the end of the list may be stored in the setting storage unit 118. it can.

  Returning to FIG. 1, as another example, the partial image data generation unit 108 can also generate reduced image data of document data, such as thumbnails, for each page. In this case, the list generation processing unit 104 can associate partial image data, character information, and reduced image data as corresponding data.

  FIG. 3 is a flowchart illustrating an example of a processing procedure of the image processing apparatus 100 according to the present embodiment.

  When the document data acquisition unit 102 acquires document data (YES in S100), the list generation processing unit 104 determines whether or not to perform list table generation processing (S102). The list generation processing unit 104 performs the list generation processing when there is a user instruction via the instruction receiving unit 112 or when the setting storage unit 118 is set to perform the list generation processing. Judge.

  When the list generation process is performed (YES in S102), the list generation process unit 104 processes the document data page by page. The detection unit 106 determines whether or not the two-dimensional code information is included in the document data acquired by the document data acquisition unit 102 (S104).

  When the detection unit 106 detects two-dimensional code information (YES in S104), the partial image data generation unit 108 generates partial image data from the document (S106). The detection unit 106 can detect the two-dimensional code information by scanning from the upper end of the document, for example. When detecting the two-dimensional code information, the detection unit 106 can output the position information where the two-dimensional code information is detected to the list generation processing unit 104. Further, the decoding unit 110 decodes the two-dimensional code information and converts it into character information (S108).

  The list generation processing unit 104 generates correspondence data in which the partial image data generated by the partial image data generation unit 108 in step S106 is associated with the character information decoded by the decoding unit 110 in step S108 (S110). The list generation processing unit 104 temporarily stores the generated correspondence data in a buffer (not shown). Subsequently, the list generation processing unit 104 determines whether or not the processing of this page (original data) has been completed (S112). Whether or not the processing of the page has been completed can be determined based on the position information at which the detection unit 106 has detected the two-dimensional code information based on whether or not the scanning has been completed to the end of the page.

  When the processing of this page is finished (YES in S112), the list generation processing unit 104 inserts a page break into the buffer storing the corresponding data (S114). On the other hand, if the page processing has not ended (NO in S112), the process returns to step S104, and the same processing is performed. In step S104, if the two-dimensional code information is not detected even when the detection unit 106 scans to the end of the page (NO in S104), the process proceeds to step S114, and the list generation processing unit 104 selects the corresponding data. Insert a page break into the buffer that stores.

  After step S114, the list generation processing unit 104 determines whether a series of document data processing has been completed (S116). If the series of document data has not been processed (NO in S116), the process returns to step S104 and the same process is performed. When a series of document data processing has been completed in step S116 (YES in S116), the list generation processing unit 104 generates a list by referring to the buffer (S118). The list generation processing unit 104 performs processing for writing the list into the writing processing unit 116 or printing the printing processing unit 114 in accordance with a user instruction or setting in the setting storage unit 118 (S120).

  If the list generation process is not performed in step S102 (NO in S102), the process proceeds to step S120, and writing or printing of document data is performed according to an instruction or the like.

  In this way, for example, by collectively setting a plurality of originals including two-dimensional code information and instructing generation of a list, these are handled as a series of processes, and only two-dimensional code information is extracted. Can be managed. In addition, for example, when two-dimensional code information is included in facsimile data in advance, by setting the generation of a list of those, it is possible to send a facsimile original when a plurality of facsimile originals are transmitted from a certain point. A list can be printed together with the print data. Further, by associating the two-dimensional code information with the character information decoded by decoding the two-dimensional code information, it is not necessary to decode the two-dimensional code information again. Here, the character information can be text data. Thereby, for example, when the character information is a URL or the like, it is possible to access a desired site by using the text data.

  The present invention has been described based on the embodiments. The embodiments are exemplifications, and it will be understood by those skilled in the art that various modifications can be made to combinations of the respective constituent elements and processing processes, and such modifications are within the scope of the present invention. .
