[First embodiment]
Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing a configuration of an image processing apparatus necessary for implementing this embodiment. The image processing apparatus includes at least a main control unit 40 and an image input unit 10, a storage unit 20, and an operation panel unit 30. In the figure, an image input unit 10 receives image data obtained by optically reading a paper document or image data input via a communication network (not shown). The storage unit 20 stores image data input by the image input unit 10 or control information of the main control unit 40, as well as image data input in the past and intermediate data such as feature amounts generated by analyzing the data. Remember.

  The storage unit 20 may be configured in the image processing apparatus, or may be configured in another apparatus that can be connected to the image processing apparatus.

  The operation panel unit 30 includes an input unit that gives an operation instruction to the image processing apparatus and a display unit that displays an operation state. FIG. 3 shows a detailed configuration of the operation panel 30. In FIG. 3, the display unit 301 is configured by a touch panel, for example. The numeric keypad 302 sets setting items related to the operation, and the start key 303 is pressed when receiving an operation start instruction to the image processing apparatus. A stop key 304 is a key for instructing to stop the operation of the image processing apparatus. A reset key 305 is used for initialization of settings by the numeric keypad 302. An operation mode setting key 306 is a key for instructing setting of an operation mode of the image processing apparatus. Note that these keys are not limited to hard keys, and may be soft keys configured on the display unit 301.

  The main control unit 40 of FIG. That is, a CPU, a ROM storing a CPU startup program, a RAM as an execution area of the program, a storage for storing intermediate data generated from image data input in the past, an HDD, an SSD, and an input / output interface (all (Not shown). The main control unit 40 controls the image input unit 10, the storage unit 20, and the operation panel unit 30. Further, the main control unit 40 includes a character determination unit 401 that determines characters included in the image data input from the image input unit 10, and matches or different points based on the layout position of the input image data. A match determination unit 402 for determination is included. In addition, the main control unit 40 controls the information displayed on the display unit 301 configured on the operation panel unit 30 according to the determination result by the coincidence determination unit 402, and the content displayed by the display control unit 403. A folder generation unit 404 that generates a folder according to the selection is included.

  Further, the main control unit 40 includes a page selection unit 406 that selects a page on which the matching portion or the mismatching portion is determined from the image data input from the image input unit 10.

  FIG. 2 shows an internal configuration of the character determination unit 401. The character determination unit 401 is mainly configured based on an OCR (Optical Character Reader). OCR is optical character recognition. When the input image data is data obtained by optically reading a paper document, the character is identified by comparing the data cut out from the input image data with a pattern stored in advance, This is converted to text data and output. Therefore, the character determination unit 401 includes a layout analysis unit 4011, a cutout unit 4012, a feature extraction unit 4013, a collation unit 4014, a dictionary unit 4015, and a temporary storage unit 4016, which are processing units that constitute the OCR. When the input image data is image data obtained via a communication network, a text data analysis unit (not shown) that analyzes text data included in the image data may be configured.

  The layout analysis unit 4011 separates the image data input from the image input unit 10 into a character area and an image area, analyzes the cluster arrangement of the character area, and determines the character recognition order. When a plurality of pages of image data configured in the same form are input, the layout analysis unit 4011 analyzes that the arrangement result of the character area and the image area configured in the image data of each page is the same. Therefore, the order of character recognition in each image data is the same.

  In other words, according to the analysis result of the layout analysis unit 4011, if the subsequent character data conversion is performed, it is possible to determine a matching portion and a different portion of characters and character strings between a plurality of document data.

  The cutout unit 4012 first divides the chunk of the character area detected by the layout analysis unit 4011 into one line, and further decomposes the divided character area into one character. The feature extraction unit 4013 extracts features of the divided characters, for example, what lines are formed in the vertical direction, the horizontal direction, and the diagonal direction. The collation unit 4014 collates the feature extracted by the feature extraction unit 4013 with the information stored in the dictionary unit 4015, and converts the character data into text data. The text data determined by the collation by the collation unit 4014 is stored in the temporary storage unit 4016.

  Note that when the input image data is image data obtained via a communication network, the text data is already included in the image data, and thus the text data is stored in the temporary storage unit 4016. In addition to the layout information, the character area coordinates, the number of characters and the number of lines obtained in this way, information on the size and orientation of the image (for example, A4 landscape orientation, etc.) is also stored in the temporary storage unit 4016 as a feature quantity. Remember. And this feature-value is used for collation with another sentence memorize | stored in the format collation part (not shown). The size of this image can be analyzed from the number of vertical and horizontal pixels and data resolution (for example, dpi (dot per inch)), and the direction can be analyzed from the direction of the character recognition result.

  A storage configuration of text data in the temporary storage unit 4016 will be described with reference to another drawing.

  FIG. 4A shows an example of the acquired image data. By the analysis of the layout analysis unit 4011, the character region in the acquired image data shown in FIG. 4A is analyzed as the layout shown by the broken lines (1) to (13) in the drawing. The cutout unit 4012 cuts out one line at a time in order from the smallest character group number, and cuts out one character at a time. Character features of the extracted character data are extracted by the feature extraction unit 4013 and converted to text data by collation with information in the dictionary unit 4015 by the collation unit 4014. At this time, if the configuration of the text data stored in the storage unit 4016 is a one-line configuration sandwiched between blank regions (white data regions) of the converted text data, the storage unit 4016 has the configuration shown in FIG. Stored as shown.

  When the main control unit 40 completes the feature amount analysis of the image data obtained by reading one document and the conversion to the text data, the main control unit 40 includes the feature amount and text data stored in the temporary storage unit 4016. Intermediate data (such as temporary file data) is generated. Next, the main control unit 40 stores the generated intermediate data in the storage unit 20 in a state associated with the feature amount read from the temporary storage unit 4016 and the text data.

  The operation of the main control unit 40 will be described with an example of image data.

  FIG. 5A to FIG. 5C are examples of image data input to the image input unit 10. Both are obtained by reading the same document form (same layout configuration) found in the form data and slip data, and some of the description contents are different. For example, the character string of “Invoice”, the character string of “Gochu” after the billing party, the company name and address of the billing source are all the same. On the other hand, the amount to the billing destination and the contents of the charge column are different.

  The determination results performed by the character determination unit 401 on the text data extracted and stored from the image data in FIGS. 5A to 5C are shown in FIGS. Show. The main control unit 40 stores the text data shown in FIGS. 5D to 5F and the image data shown in FIGS. 5A to 5C and intermediate data indicating the feature values in the storage unit 20. Remember. In this embodiment, after all the character data extracted from FIG. 5A to FIG. 5C input to the image input unit 10 is converted to text data, the text data is read from the temporary storage unit 4016, The data is stored in the storage unit 20. However, the control of the storage unit 20 by the main control unit 40 is not limited to this. That is, control may be performed so that the text data stored in the temporary storage unit 4016 is stored in the storage unit 20 for each image data input to the image input unit 10.

  When the main control unit 40 stores the text data extracted from all the input image data of the image input unit 10 and the digitized intermediate file in the storage unit 20, the main control unit 40 performs matching determination control. The coincidence determination control by the main control unit 40 is performed by comparing the text data extracted from each input image data stored in the storage unit 20 by the coincidence determination unit 402. In addition, since the order of the text data memorize | stored in the memory | storage part 20 is based on the determination result of the layout analysis part 4011 of the character determination part 401, even if it is the same text data, it corresponds with the text data memorize | stored in a different order. No judgment is made. That is, the order of the text data extracted from the input image data includes the position information of the input image data. Therefore, even if the same text data is extracted, if the extraction order is different, it can be determined that the text data exists in another position. Therefore, the coincidence determination is performed based on the contents and order (position information) of the text data stored in the storage unit 20. In this description, the position information of the text data extracted from the input image data is based on the order in which the text data is extracted. However, the present embodiment is not limited to this. For example, the position information of the extracted text data in the input image data is separately created, and the extracted text data and the position information are stored in association with the storage unit 20. And it is good also as a form which performs the coincidence determination by the coincidence determination part 402, or a disagreement determination using two information of the extracted text data and position information.

  Next, details of match determination and mismatch determination will be described. Focusing on the text data corresponding to the range 501, range 503, and range 505 shown in FIG. 5D, which is the text data determination result extracted from the input image data with reference to the input image data in FIG. 5A. To do. The text data corresponding to the ranges 501, 503, and 505 matches the text data corresponding to the ranges 501, 503, and 505 included in the input image data (e) and (f). Therefore, the portions corresponding to the ranges 501, 503, and 505 of the text data extracted from the input image data in FIGS. 5A, 5B, and 5C are the same. Can be judged. On the other hand, the text data corresponding to the range 502, range 504, and range 506 shown in FIG. 5D is input image data in the range 502, range 504, and range 506 included in FIGS. 5E and 5F. Does not match the text data corresponding to. Therefore, the portions corresponding to the ranges 502, 504, and 506 of the text data extracted from the input image data in FIGS. 5A, 5B, and 5C are the same. It can be determined that there is no.

  Note that the match determination by the match determination unit 402 may not be complete match with the text data stored in the storage unit 20. The conversion of character data into text data by OCR is based on collation between the characteristics of the character data extracted by the feature extraction unit 4013 and the data stored in the dictionary unit 4015. May be accompanied by misjudgment. Therefore, the final matching determination may be performed based on the number of matching determinations for the character string. For example, when text data for 8 characters matches text data for 10 characters, control may be performed so that the character string is determined to be matched.

  When the match determination control by the match determination unit 402 ends, the main control unit 40 performs display control by the display control unit 403. The display control reflects the match determination result by the match determination unit 402 to the intermediate file data obtained by digitizing the image data input to the image input unit 10. FIG. 6A is a diagram illustrating a display state of the operation panel unit 30 when the input image data of FIG. 5A is a display target.

  In FIG. 6A, all the contents described for the positions common to each form among the plurality of read forms in FIGS. 5A to 5C by the coincidence determination unit 402 are all. The character string determined to match in the form is displayed with shading indicated by reference numeral 601. On the other hand, it is determined that the contents described in the positions common to the respective forms among the plurality of read forms in FIGS. 5A to 5C do not match (non-match) in all the forms. The character string thus obtained is displayed by shading indicated by reference numeral 602. The display method of matching and mismatching is not limited to this display form, and any display method can be used as long as it can distinguish between a matched character string and a mismatched character string. For example, if the display unit 301 configured in the operation panel unit 30 can display in color, the matched character string and the mismatched character string may be displayed in different colors. Further, if the display unit 301 can display only a single color, a display form such as lighting or blinking may be used.

  Furthermore, it is not necessary to display all the matched character strings and the mismatched character strings. For example, the storage unit 20 pre-registers the character size (font size) and the character string length to be displayed for matching and mismatching, and the matching character string and the mismatching character string corresponding to the registered contents. May be displayed in a form that can be distinguished only. FIG. 6B is a display example when the display of the matched character string and the mismatched character string is limited to a character (font) larger than a predetermined threshold or the length of the character string. First, since the characters (fonts) larger than the predetermined threshold are used, all the small character strings in FIG. 6A are not displayed. In addition, by restricting the length of the character string, long character strings such as dates and fixed phrases are not displayed.

  FIG. 6C shows keywords, “invoice”, “stock”, and “(stock)” registered in the storage unit 20 as display items for matching and mismatching, and characters including these registered keywords. It is an example of a display state in the case of displaying in the form which can discriminate | determine a match and mismatch only with respect to a column. By controlling in this way, only the characteristic matched character string and the unmatched character string of the input image data are displayed, and convenience at the time of selection can be improved.

  When the display control by the display control unit 403 is completed, the main control unit 40 waits for selection of the coincidence portion and the disagreement portion displayed on the display unit 301. The subsequent control by the main control unit 40 differs depending on whether the coincidence portion is selected or not. Note that the method for selecting the coincidence portion and the disagreement portion depends on the function of the display unit 301. If the display unit 301 is a touch panel, the main control unit 40 switches control according to pressing of a coincidence place or a non-coincidence place and the pressed coordinate position. When the display unit 301 is not a touch panel, the main control unit 40 switches control according to the selection result of the coincidence portion and the mismatch portion by the key operation (not shown) configured in the operation panel unit 30.

  The main control unit 40 performs control using the selected character string for matching determination when a matching portion is selected. When the matching portion is selected, the main control unit 40 selects a mismatching character string corresponding to the selected mismatch determination position. Perform the control used. In the present embodiment, a description will be given of control for switching the folder generation method for storing the digitized result of the input image data by the folder generation unit 404 depending on whether a matching part is selected or a mismatching part is selected.

  FIG. 7A shows a folder generation control result by the folder generation unit 404 when the character string “invoice” that has been determined to match is selected. The folder generation unit 404 uses the selected character string as a folder name to be generated in the storage unit 20 when a character string that has been determined to match is selected from the plurality of read image data. For example, if the selected character string for matching is “invoice”, “invoice” is set as the folder name (701). When the character string that has been determined to match is selected, the intermediate file data after digitization input by the image input unit 10 is stored as an integrated file (one file) in the generated folder. That is, the intermediate files shown in FIGS. 5A, 5B, and 5C are integrated, and the final digitized file is stored in the generated folder using the selected match determination character string. Store (702). In addition, regarding the file name stored in the storage unit 20, the selected match determination character string is used as a part of the file name. For example, in the case of the “invoice”, a file name (eg, invoice_001) in which a serial number or the like is added to the “invoice”. By controlling in this way, it is possible to easily generate a folder name and a file name using a character string intended by the user.

  Next, the control of the folder generation unit 404 when a mismatched portion is selected from a plurality of read image data will be described. FIG. 7B shows a folder generation control result by the folder generation unit 404 when the character string “AAA Co., Ltd.” that has been determined to be inconsistent is selected. When a character string that has been determined to be inconsistent is selected, the folder generation unit 404 uses each character string that exists at the selected character string position as a folder name to be generated in the storage unit 20. The character string determined to be inconsistent and selected in the present embodiment is “AAA Corporation”. Therefore, the position of the character string “AAA” in each image data, that is, the character string existing before “Gochu” in each input image data, is set as the respective folder name (703, 704, 705). To do. That is, folders with names “AAA Co., Ltd.”, “BBB Co., Ltd.”, and “CCC Engineering” are generated. When a character string that has been determined to be inconsistent is selected, the digitized image data input by the image input unit 10 is stored as a separate file in the generated folder.

  That is, if the input image data is FIG. 5A, the digitized intermediate file data (706) of FIG. 5A is stored in the folder named “AAA Corporation”. Similarly, if the input image data is FIG. 5B, the computerized intermediate file data (707) of FIG. 5B is stored in the folder named “BBB Co., Ltd.”. If the input image data is FIG. 5C, the digitized intermediate file data (708) of FIG. 5C is stored in the folder named “CCC construction company”. For each file name in the created folder, each character string existing at the selected mismatch determination position is used as part of the file name. For example, in the case of “AAA Co., Ltd.”, a file name (eg, AAA Co., Ltd._001) in which a serial number is assigned to “AAA Co., Ltd.” is stored in the folder named “AAA Co., Ltd.” (intermediate) Rename and store file data). By controlling in this way, the folder name and the file name using the character string intended by the user can be easily generated.

  FIG. 14 is a diagram illustrating a configuration of the page selection unit 406. The page selection unit 406 is executed by the CPU in the main control unit 40. When the input image is a plurality of documents constituting one document with a plurality of pages, the page number setting unit 4051 sets the number of pages constituting the one document. As a result, the main control unit 40 compares the first pages of the documents. FIG. 15 is a diagram illustrating a specific input image. First, an invoice 1501 addressed to “AAA Co., Ltd.” is a set of documents including two fee breakdown documents 1502. An invoice 1503 addressed to “BBB Co., Ltd.” is a set of documents including two fee breakdown documents 1504. The invoice 1505 addressed to the “CCC engineering firm” is a set of documents consisting of two fee breakdown documents 1506. When inputting a document as shown in FIG. 15, the page number setting unit 4051 designates two pages by user input. As a result, the main control unit 40 compares the bill 1501, the bill 1503, and the bill 1505. When these documents are stored, one page is stored as two documents and one document is stored as a file. Here, the page selection unit 406 performs comparison by another page in the document when there is no mismatch in the image comparison result.

  The comparison page position setting unit 4052 in FIG. 14 sets the position of the page to be compared in the document. The main control unit 40 compares the images at the page positions set by the page position setting unit 4052. When the second page is designated in the document shown in FIG. 15, the main control unit 40 compares the invoices 1502, 1504, and 1506, and stores them as one file in units of documents.

  In this way, a document composed of two pages is compared for each page of each document.

  The approximate determination unit 4053 in FIG. 14 calculates the degree of approximation of the subsequent page from the feature amount of the image with respect to the first page of the input image, and determines whether the page is an approximate page. For example, in a document as shown in FIG. 15, 1503 and 1505 approximate to the first invoice 1501 are selected as approximate pages and set as comparison pages. As the feature amount calculation method of the approximate determination unit 4053, line / contour detection, histogram, and the like are performed by the CPU or ASIC in the main control unit 40, but any method may be used. Further, the threshold value setting unit 4054 in FIG. 14 sets the feature amount of the first page and the threshold value designated by the user for determining that the other pages are approximate pages. Further, the page selection unit 406 sets not only the approximate page but also the last page in the document as a comparison target for matching / mismatching.

  FIG. 16 is a second diagram showing a specific input image. An invoice 1601 addressed to “AAA Co., Ltd.” is a set of three documents, fee breakdown statements 1602 and 1603. One bill 1604 addressed to “BBB Corporation” is one document. The invoice 1605 addressed to the “CCC engineering shop” is a set of documents including two fee breakdown documents 1606. When a document as shown in FIG. 16 is input, the page number setting unit 4051 sets the target pages 1601, 1604, and 1605 determined by the approximation determination unit 4053. The main control unit 40 compares the invoices 1601, 1604, and 1605, and stores them as one file in document units. Here, the page selection unit 406 determines that 1601 to 1603 are one document, 1604 is one document, and 1605 and 1606 are one document. Here, since it is considered that there is a standard document on the last page of each document, the page selection unit 406 also compares the last pages according to the user's specification. However, there may be a case where the position of the object to be compared is not the same position on the image as in the case where the sum of the last pages 1603 and 1606 of the document is the object to be compared. Here, the page selection unit 406 performs a comparison by matching the document portion before the trailing edge margin of the final page image with the position of the portion where the trailing edge margin occurs.

  Next, the control flow of the main control unit 40 will be described. FIG. 8 is a diagram showing a control flow in the first embodiment. The processing in each step of this flow is performed by reading a computer-executable program describing the following procedure from a ROM (not shown) onto a RAM (not shown) and then executing the program by a CPU (not shown). Implemented by executing.

  When the user selects an operation mode for digitizing a plurality of pieces of image data configured in the same form (step S101), the image input unit 10 receives the image data (step S102).

  The received image data is scanned image data if it is accompanied by optical reading, and is received data if it is input via a communication network. In step S103, the image input unit 10 determines whether all image data has been input. If the image input unit 10 determines that all image data has been input, the process proceeds to step S104.

  The input image data is input by reading a plurality of sets of originals including a set of originals composed of a plurality of pages.

  In step S <b> 104, the main control unit 40 performs character determination processing by the character determination unit 401. The character determination processing by the character determination unit 401 performs layout analysis, data extraction, feature extraction, verification, and verification result storage for each sheet input by the image input unit 10.

  If the main control unit 40 determines in step S105 that the operation mode set by the user is not to digitize a plurality of image data configured in the same form, the process proceeds to step S112. In step S112, the folder name to be generated is a predetermined name. Then, an electronic file using text data obtained by the character determination unit 401 is stored in the generated folder. When the main control unit 40 determines in step S105 that the operation mode set by the user is an operation mode for digitizing a plurality of image data configured in the same form, the process proceeds to step S120. After a flow of step S120 described later has passed and the processing target page has been determined, the process proceeds to step S106. In step S <b> 106, a match determination process is performed by the match determination unit 402. When the coincidence determination process by the coincidence determination unit 402 ends, in step S107, the display control unit 403 of the main control unit 40 performs display control of the coincidence portion and the disagreement portion.

  In step S108, when the coincidence portion is selected by the user, the process proceeds to step S109. Then, the folder generation unit 404 of the main control unit 40 generates a folder reflecting the contents of the selected matching part, and stores a single file in which intermediate files of all input image data are integrated in the folder. . On the other hand, if a mismatched portion is selected in step S108, the process proceeds to step S110. If it is determined in step S110 that a different location has been selected, the process proceeds to step S111. In step S111, the folder generation unit 404 of the main control unit 40 generates folders that reflect the contents of the selected mismatched location in each input image data, and the corresponding document is stored in each folder. Store unit intermediate files. Note that the name of the intermediate file stored in steps S109 and S111 is a name corresponding to the selection of the matching part and the mismatching part already described.

  FIG. 17 is a flow showing details of the processing executed in step S120, and is a control flow of the page selection unit 406. This control flow is executed to determine whether or not the read page is a comparison target page.

  In step S401, the main control unit 40 determines whether or not the number of pages of the document has been designated by the user. If designated, the process proceeds to step S402, and if automatic detection is designated, the process proceeds to step S403. In step S402, the main control unit 40 determines whether the current page is a target page to be compared. If the current page is the target page, the main control unit 40 proceeds to the next step. If not, the main control unit 40 proceeds to step S408. In step S403, the main control unit 40 proceeds to step S404 if a threshold value is specified, and proceeds to step S405 if no threshold value is specified. In step S404, the main control unit 40 acquires a threshold value designated by the user and proceeds to step S406. In step S405, the main control unit 40 acquires a default threshold value and proceeds to step S406. In step S406, the main control unit 40 compares feature amounts from the acquired threshold value, and proceeds to step S407. In step S407, the main control unit 40 determines whether it is an approximate page of the comparison page from the comparison result of the feature amount. If it is an approximate page, the process proceeds to the next step, and if it is determined that the page is not an approximate page, the main control unit 40 proceeds to step S408. move on. In step S408, the main control unit 40 performs primary recording as a page belonging to the document of the previous page, and reads the next page (step S409).

  As described above, in the first embodiment, when digitizing a plurality of image data in which the format of all pages is not necessarily the same, the content selected by the user (selection of coincidence portion / non-coincidence portion selection) A folder is constructed for each document in a form corresponding to the above. Furthermore, the computerized file name and file format stored in the folder are also adapted to the contents selected by the user (selection of matching part / selection of non-matching part), so that convenience for the user can be improved. I can do it.

[Second Embodiment]
In the first embodiment, the folder configuration, file configuration, and further the folder name and file name are appropriately controlled according to the content selected by the user. In the second embodiment, a description will be given of a case where the file structure and the file name are controlled according to the content selected by the user.

  The configuration of the image processing apparatus is as shown in FIG. 9 instead of FIG. 1, and in this embodiment, a file generation unit 405 is provided instead of the folder generation unit 404.

  FIG. 10 is a diagram showing a file management method for digitized image data in this embodiment. In the figure, components having the same functions as those in the first embodiment are given the same reference numerals, but the processing unit unique to this embodiment is only the file generation unit 405 configured in the main control unit 40. Therefore, the functions and operations of the character determination unit 401, the coincidence determination unit 402, and the display control unit 403 configured in the image input unit 10, the storage unit 20, the operation panel unit 30, and the main control unit 40 have been described in the first embodiment. Is the same. On the other hand, in the present embodiment, the operation after the display control by the display control unit 403 configured in the main control unit 40 is different from that in the first embodiment. That is, the control after selection of the coincidence portion and the disagreement portion by the user is a feature of the processing executed in this embodiment. For this reason, hereinafter, the control at the time of selecting the coincidence portion and the control at the time of selecting the non-match portion will be described. Further, input image data applied to the following description is assumed to be as shown in FIG.

  FIG. 10A shows a file generation control result by the file generation unit 405 when the character string “invoice” that has been determined to match is selected. The file generation unit 405 uses the selected character string as the file name to be generated in the storage unit 20 when the character string that has been determined to match is selected. For example, if the selected character string for matching determination is “invoice”, “invoice” is set as the file name (1001). In addition, the intermediate files generated by the character determination unit 401 in FIGS. 5A, 5B, and 5C are stored in an integrated form. By controlling in this way, a file name using a character string intended by the user can be easily generated.

  Next, the control of the file generation unit 405 when a mismatched part is selected will be described. FIG. 10B shows a folder generation control result by the file generation unit 405 when the character string “AAA Co., Ltd.” that has been determined to be inconsistent is selected. When a character string that has been determined to be inconsistent is selected, the file generation unit 405 uses each character string that exists at the selected character string position as a file name to be generated in the storage unit 20. The character string for mismatch determination selected in the present description is “AAA Co., Ltd.”. Therefore, the position of the character string “AAA Co., Ltd.” in each image data, that is, the character string existing before “Gochu” in each input image data is set as the respective file name (1002, 1003, 1004). . When a character string that has been determined to be inconsistent is selected, the digitized image data input by the image input unit 10 is stored as a separate file.

  That is, if the input image data is FIG. 5A, the digitized file of FIG. 5A is stored as the file name AAA. Similarly, if the input image data is FIG. 5 (b), the file name is BBB, and the electronic file of FIG. 5 (b) is stored, and the input image data is FIG. 5 (c). If there is, the computerized file shown in FIG. 5C is stored with the file name as the CCC contractor. That is, in this embodiment, the intermediate file of each input image data is renamed and stored. By controlling in this way, a file name using a character string intended by the user can be easily generated.

  Next, the control flow of the main control unit 40 will be described. FIG. 11 is a diagram showing a control flow in the present embodiment. The processing in each step of this flow is performed by reading a computer-executable program describing the following procedure from a ROM (not shown) onto a RAM (not shown) and then executing the program by a CPU (not shown). Implemented by executing.

  When the user selects an operation mode for digitizing a plurality of pieces of image data configured in the same form (step S201), the image input unit 10 receives the image data (step S202). The received image data is scanned image data if it is accompanied by optical reading, and is received data if it is input via a communication network. If the image input unit 10 determines in step S203 that all image data has been input, the process proceeds to step S204.

  The input image data is input by reading a plurality of sets of originals including a set of originals composed of a plurality of pages.

  In step S <b> 204, the main control unit 40 performs character determination processing by the character determination unit 401. The character determination processing by the character determination unit 401 is layout analysis, data cutout, feature extraction, verification, and storage of verification results for each sheet input by the image input unit 10.

  Subsequently, in step S205, the main control unit 40 determines whether or not the operation mode set by the user is a mode for digitizing a plurality of image data configured in the same form. If not, the process proceeds to step S212. In step S212, the file name to be generated is stored as a predetermined name. On the other hand, if the main control unit 40 determines in step S205 that the operation mode set by the user is an operation mode for digitizing a plurality of image data configured in the same form, the main control unit 40 proceeds to step S120. move on. After the flow of step S120 has passed and the page to be processed has been determined, the process proceeds to step S206. In step S206, the coincidence determination unit 402 performs a coincidence determination process. When the coincidence determination process by the coincidence determination unit 402 ends, the process proceeds to step S207, and the display control unit 403 of the main control unit 40 performs display control of the coincidence portion and the disagreement portion.

  Subsequently, when the coincident part is selected by the user in step S208, the process proceeds to step S209. In step S209, the file generation unit 405 of the main control unit 40 generates a file reflecting the contents of the selected matching portion. The file to be generated is a single file obtained by integrating intermediate files of all input image data. On the other hand, if it is determined in step S208 that a mismatched portion has been selected, the process proceeds to step S210. If it is determined in step S210 that the location selected by the user is a different location, the process proceeds to step S211. In step S211, the file generation unit 405 of the main control unit 40 generates files in document units that reflect the contents of the selected inconsistent position in each input image data. Note that the names of the files stored in step S209 and step S211 are names corresponding to the selections of the matching points and the mismatching points already described.

  As described above, in this embodiment, when digitizing a plurality of image data in which the format of all pages is not necessarily the same, according to the content selected by the user (selection of coincidence / non-coincidence) A file is constructed for each document in the form. Furthermore, since the file name of the stored electronic image data is also adapted to the content selected by the user (matching location selection / non-matching location selection), user convenience can be improved.

[Third embodiment]
Next, a third embodiment of the present invention will be described. In this embodiment, when digitizing a plurality of pieces of image data configured in the same form, the operation mode of whether the files to be generated are integrated (generated as a single file) or individually generated is preliminarily set. It relates to control when set to. The configuration of the image processing apparatus according to the present embodiment is the configuration illustrated in FIG. 1 and includes an image input unit 10, a storage unit 20, an operation panel unit 30, and a main control unit 40. In the following description, the image data input to the image input unit 10 is the image data shown in FIG.

  Hereinafter, the control flow in the present embodiment will be described with reference to the drawings. FIG. 12 is a diagram showing a control flow in the present embodiment. The processing in each step of this flow is performed by reading a computer-executable program describing the following procedure from a ROM (not shown) onto a RAM (not shown) and then executing the program by a CPU (not shown). Implemented by executing.

  In step S301, when the user sets an operation mode for generating a plurality of pieces of image data configured in the same form in an integrated manner or individually, the process proceeds to step S302. In step S302, the image input unit 10 receives image data. As in the first and second embodiments, the received image data is scanned image data if it is optically read, and is received data if it is input via a communication network. . The image input unit 10 continuously accepts image data until all the image data is input (No in step S303).

  If it is determined in step S303 that the image input unit 10 has input all image data, the process proceeds to step S304.

  The input image data is input by reading a plurality of sets of originals including a set of originals composed of a plurality of pages.

  In step S <b> 304, the main control unit 40 performs character determination processing by the character determination unit 401. The character determination processing by the character determination unit 401 is layout analysis, data cutout, feature extraction, verification, and storage of verification results for each sheet input by the image input unit 10.

  When the character determination by the character determination unit 401 ends, the process proceeds to step S120. After the flow of step S120 has passed and the processing target page has been determined, the process proceeds to step S305, where the match determination unit 402 of the main control unit 40 performs a match determination process. Subsequently, in step S306, the main control unit 40 proceeds to step S307 when the operation mode set by the user is an operation mode in which the digitized result of the input image data is generated. In step S307, the display control unit 403 performs display in a form in which the character string determined to be coincidence by the coincidence determination unit 402 can be selected.

  An example of the state of the operation panel unit 30 in this case is shown in FIG. In FIG. 13A, the character string indicated by shading matches the input image data, that is, FIG. 5A, FIG. 5B, and FIG. It is a character string determined to be. Note that the character string indicated by shading is selectable by the user. Moreover, the character string shown lightly is a character string that has been determined to be inconsistent in the input image data by the match determination unit 402 and cannot be selected by the user. It should be noted that the display of the character string determined to be coincident that can be selected by the user may be a color display by color display or a display form such as lighting / flashing.

  In step S308, when the user selects a character string determined to match, the process proceeds to step S309, and the main control unit 40 stores a folder with a folder name using the selected character string in the storage unit 20. Generate. Then, the intermediate files of FIGS. 5A, 5B, and 5C stored in the storage unit 20 are integrated and stored in a folder with a file name using the selected matching character string. To do. For example, when the user selects the character string “invoice” for matching, the folder name is “invoice”, and the folder name is shown in FIGS. 5 (a), 5 (b), and FIG. The file in which 5 (c) is integrated is stored under the name of invoice_001.

  On the other hand, in step S306, the main control unit 40 proceeds to step S310 when the operation mode set by the user is an operation mode for individually generating the digitized result of the input image data. In step S310, the display control unit 403 performs display in a form in which the character string that has been determined to be inconsistent by the match determination unit 402 can be selected.

  An example of the state of the operation panel unit 30 in this case is shown in FIG. In FIG. 13B, the character string indicated by shading is a character string that has been determined to be inconsistent in the input image data, that is, the input image data, by the match determination unit 402. Note that the character string indicated by shading is selectable by the user. Further, the thinly illustrated character string is a character string that is determined to be a match by the match determination unit 402 in FIG. 5 (a), FIG. 5 (b), and FIG. 5 (c) as a whole, and cannot be selected by the user. It is a thing. Note that the display of the character strings determined to be inconsistent that can be selected by the user may be color-coded by color display or may be a display form such as lighting / flashing.

  In step S311, the main control unit 40 proceeds to step S312 when it is determined by the user that the character string determined to be inconsistent has been selected. In step S312, a folder using each character string at the selected mismatched character string position in the input image data is generated in the storage unit 20, and the generated document unit file is stored in the storage unit 20.

  Specifically, the intermediate files shown in FIGS. 5A, 5B, and 5C are stored in the corresponding folders. For example, if the character string “AAA Co., Ltd.” for determining the inconsistency is selected by the user, a folder is created with the names “AAA Co., Ltd.”, “BBB Co., Ltd.”, and “CCC Contractor”. In each of the folders, the intermediate files shown in FIGS. 5A, 5B, and 5C are renamed and stored in AAA_011, BBB Co., Ltd._001, and CCC engineering company_001. .

  It should be noted that in the present embodiment, the match determination character string or the mismatch determination character string to be displayed on the display unit 301 may not be all match determination character strings or all mismatch determination character strings. For example, the storage unit 20 pre-registers the character size (font size) and the character string length to be displayed for matching and mismatching, and the matching character string and the mismatching character string corresponding to the registered contents. May be displayed only. Alternatively, keywords may be pre-registered in the storage unit 20, and only the matched character strings and unmatched character strings corresponding to the pre-registered keywords may be displayed.

  As described above, according to the present embodiment, according to a preset operation mode, a folder name and a file name candidate generated for each document are determined as a character string determined to match or as a mismatch. User convenience is improved by using a character string.
