  In the technique of Patent Document 1, it is troublesome for the user to designate file name information to be renamed in the reading order of the original document. The present invention has been made in view of such problems, and an object of the present invention is to automatically assign a file name suitable for the content of an original to an image without the user specifying the file name one by one.

  In order to solve the above problems, a file management apparatus according to the present invention includes an image acquisition unit that acquires an image of an original, an image storage that stores an image of the original, and an original from an image of the original stored in the image storage A page information extracting unit that extracts page information indicating the affiliation of the document, and a file name assigning unit that assigns a file name of the image of the document according to the page information extracted by the page information extracting unit.

  According to the present invention, since the extracted page information is added to the file name of the document image, the page number of the document can be easily understood from the file name, and a serial number is simply added to the file name to determine which image This prevents you from knowing whether or not it corresponds to a manuscript page. Also, there is no need for the user to specify an appropriate file name.

  The page information includes information indicating the number of pages of the document, information indicating the title of the document, document creator, other information sufficient to identify the affiliation of the document, or information combining a part or all of these.

  The page information extraction unit may extract page information from a character string surrounded by margins in the document image.

  Normally, it is considered that the page information is often separated from the text and surrounded by margins, so that the page information can be extracted efficiently.

  The file management apparatus further includes a page position information acquisition unit that acquires page position information that is information related to a position of page information extracted from an image of a document, and a page position storage unit that stores page position information. The page information extraction unit may extract page information from an image of another document in a predetermined area based on the page position information.

  If page information has already been extracted from an image of a certain original, it is considered that the page information is also present at substantially the same position as the position indicated by the page position information for other original images. Therefore, it is possible to extract the page information more efficiently than searching the page information for the entire area of the image.

  The file management apparatus may further include a title information extraction unit that extracts title information indicating the title of the document from the image of the document.

  The title information extraction unit may extract title information from a character string surrounded by margins in the document image.

  Normally, it is considered that the title information is often surrounded by a blank space separated from the text, so that page information can be extracted efficiently.

  The file management apparatus further includes a title candidate registration unit for registering document title candidates, and the title information extraction unit extracts character strings that match the document title candidates registered in the title candidate registration unit as title information. You may make it do.

  If the manuscript is a document having a typical content such as an in-house document, title information can be efficiently extracted from a character string if a predictable title is registered in advance as a candidate.

  The file management apparatus may further include a title designation unit that designates a desired character string to be used as title information in the extracted character string.

  In this way, even if there are a plurality of types of extracted character strings, the user can arbitrarily specify title information from among them.

  The file name assigning unit may assign the file name of the document image according to the title information.

  Since the extracted title information is added to the file name of the document image, the title of the document can be easily understood from the file name.

  The file management apparatus further includes a folder creation unit that creates a folder corresponding to the title information in the image storage unit, and a file management unit that stores an image of the document from which the title information is extracted in the folder corresponding to the title information. You may prepare.

  In this way, images can be classified by folder for each title.

  A page format determination unit that determines the format of the page information may be further provided, and the file management unit may store images having a common page information format in a common folder.

  In this way, images having page information of the same format are classified into a common folder, and documents of different formats can be prevented from being mixed in the same folder as much as possible.

  A step of acquiring a document image, a step of storing the document image, a step of extracting page information indicating the number of pages of the document from the stored document image, and a file of the document image according to the extracted page information A file management method including the step of assigning a name is also included in the present invention.

  According to the present invention, since the extracted page information is added to the file name of the document image, the page number of the document can be easily understood from the file name, and a serial number is simply added to the file name to determine which image This prevents you from knowing whether or not it corresponds to a manuscript page. Also, there is no need for the user to specify an appropriate file name.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

  FIG. 1 is a functional block diagram of a file management apparatus 10 according to a preferred embodiment of the present invention. The file management apparatus 10 includes a monitor 106 with a touch panel and a communication line interface 108 capable of transmitting and receiving necessary information via a network such as the Internet. The file management apparatus 10 is also provided with a USB interface 206 for data communication with the image acquisition apparatus 200 configured by a scanner or the like. On the monitor 106 with a touch panel, a list of images and various operation buttons are displayed.

  The file management apparatus 10 includes a central processing unit (CPU) 110 that performs overall control of the file management apparatus 10, a ROM in which a program for operating the CPU 110 is written, and a work area when the CPU 110 executes processing. A system memory 112 configured by a RAM, a display controller 114 that outputs information to be displayed on the monitor 106 with a touch panel, and an input controller 116 that receives input of various types of information by pressing applied to the monitor 106 with a touch panel. .

  In addition, the file management apparatus 10 includes a hard disk unit (HDD) 118 that temporarily stores an image from the image acquisition apparatus 200, and an HDD controller 119 that controls storage of information in the HDD 118 or reading of information from the HDD 118. Prepare.

  The image acquisition apparatus 200 includes various scanners such as a line CCD scanner, and is connected to the CPU 110 via a USB interface 206. The image acquisition apparatus 200 continuously scans a plurality of documents set on a mount (not shown) one by one, reads the documents, and converts them into image files (document images). The document image is stored in the HDD 118.

  Note that the image acquisition device 200 may be configured by various imaging devices such as a digital camera and a video camera. That is, a document may be captured by various imaging devices, and an image file obtained by the imaging may be stored in the HDD 118 as a document image.

  FIG. 2 is a main part configuration diagram of the file management apparatus 10. The CPU 110 includes, as processing units (modules), a scanner control unit 110a, a page information extraction unit 110b, a file name assignment unit 110c, a page position information acquisition unit 110d, a title information extraction unit 110e, a title candidate registration unit 110f, and a folder creation unit 110g. A file management unit 110h and a page format determination unit 110i. Each processing unit is stored in the ROM as a program. The functions of these processing units will be described later.

  The system memory 112 includes a page position storage unit 112a that is an area for storing page position information described later. The HDD 118 serves as an image storage unit that stores document images.

  Hereinafter, processing executed by the CPU 110 will be described with reference to the flowchart of FIG.

  In S <b> 1, the scanner control unit 110 a controls the image acquisition apparatus 200 to scan the document and store the document image in the HDD 118. The original image may be stored in the HDD 118 after various image processing such as density adjustment is performed. Note that serial numbers k (k = 1, 2, 3,..., N, where n is the total number of scanned documents) are provisionally assigned to the images stored in the HDD 118 as file names. Hereinafter, each original image is represented by Ik, and steps S1 to S15 are looped for k = 1 to n.

  In S2, the file management unit 110h determines whether or not page position information (information regarding the position where the page information is arranged in the document image; the same applies hereinafter) is stored in the page position storage unit 112a. If page position information is stored, the process proceeds to S3, and if not stored, the process proceeds to S5.

  The page position information is stored in S8 or S11 described later. For this reason, even if S2 is executed for at least the first original image, the page position information is not stored, and the process automatically proceeds to S5.

  In S3, the page information extraction unit 110b extracts a character string surrounded by margins from the document image Ik in a predetermined peripheral area based on the stored page position information.

  For example, there is a document image Ik as shown in FIG. 4, and a pair of diagonal points P0 (X0, Y0) and P1 (X1, Y1) in the XY plane coordinates with the lower left corner of the document image Ik as the origin O is a page. Assume that it is stored in the page position storage unit 112a as position information. In this case, the page information extraction unit 112b extracts a character string from the rectangular area R0 defined by the diagonal points P0 and P1.

  Alternatively, it is assumed that a pair of diagonal points P2 (X2, Y2) and P3 (X3, Y3) in the XY plane coordinates are stored in the page position storage unit 112a as page position information. In this case, the page information extraction unit 112b extracts a character string from the rectangular area R1 defined by the diagonal points P2 and P3.

  In S4, the title information extraction unit 110e determines whether or not title information (information indicating the title of the document; one aspect of page information) is included in the character string extracted from the region R1 of the document image Ik. This determination is performed as follows, for example. That is, when a character string matching a predetermined title character string registered in the HDD 118 by the title candidate registration unit 110f in advance is included, it is determined that the title is included. Alternatively, the title information extraction unit 110e displays the extracted character string on the touch panel monitor 106, and instructs the touch panel monitor 106 to input whether or not this character string is a title. If an instruction indicating that the title is input, it is determined that the title is included. If the title is included, the process proceeds to S8, and if the title is not included, the process proceeds to S5.

  Note that the title candidate registration unit 110f may register a title character string arbitrarily input from the touch panel 106 in the HDD 118 as a title candidate. For the title character string, for example, a comprehensive or generic character string such as “literature”, “medicine”, “science”, “business”, or an individual specific character string such as “tanka” or “poetry”. Allow multiple registrations.

  Then, when there are a plurality of predetermined title character strings that match the character string extracted from the document image Ik, the title information extraction unit 110e displays these as title candidates on the touch panel monitor 106, and any one of the title candidates is displayed. The title information may be determined by inputting a title candidate from the touch panel monitor 106.

  In S5, the page information extraction unit 112b extracts a character string from the area surrounded by the inner margin of the entire area of the document image Ik. For example, in the case of the document image Ik in FIG. 3, character strings are extracted from all of the regions R0 to R5 surrounded by the margins.

  In S6, the title information extraction unit 110e determines whether title information is included in the character string extracted from the document image Ik. This determination is the same as in S4. If the title information is included, the process proceeds to S7, and if the title is not included, the process proceeds to S10.

  In S7, the folder creation unit 110g creates a folder corresponding to the title information extracted from the document image Ik (for example, a folder assigned title information as a folder name) in the HDD 118. The file management unit 110h stores the document image Ik obtained by extracting the title information in this folder. Thereby, the document image Ik can be classified by the folder for each title information extracted from the document image.

  In S8, the page position information acquisition unit 110d acquires the page position information from the document image Ik and stores it in the page position storage unit 112a. Next, the page information extraction unit 110b determines whether or not the extracted character string includes page number information (information indicating the number of pages; one aspect of page information). This determination includes determination for simply distinguishing the number from the number of pages. For example, the numbers detected from the four corner areas or the upper, lower, left, and right peripheral areas of the document image Ik are determined as the page number information. Alternatively, when a character string in which the total page number and the corresponding page number are integrated (for example, 1/5), it is determined that page number information is included. If page number information is included, the process proceeds to S14. If page number information is not included, the process proceeds to S9.

  In S9, the file name assigning unit 110c assigns a predetermined character string including characters or symbols indicating that the title, serial number, and number of pages extracted from the document image Ik could not be extracted as the file name of the document image. . For example, if the extracted title is “Literature Collection”, the serial number is “001”, and the character or symbol indicating that the number of pages could not be extracted is “?”, The file name is “Literature Collection 001?”. It is added to the original image.

  In S10, it is determined whether or not the page number information is included in the character string extracted from the page information extraction unit 110b original image Ik. This determination is similar to S8.

  In S11, the page position information acquisition unit 110d acquires the page position information from the document image Ik and stores it in the page position storage unit 112a. Next, the page format determination unit 110i sets the format of page information extracted from the document image Ik and the format of page information extracted from another document image Ij (j ≠ k) for all other document images Ij. Compare.

  In S12, the page format determination unit 110i determines whether another document image Ij (j ≠ k) having the same format as the page information extracted from the document image Ik is stored in the HDD 118 as a result of the comparison. To do. The common page information format means that, for example, features such as the number of pages, title font, size, layout, and format are common. If another document image Ij is stored, the process proceeds to S13, and if not stored, the process proceeds to S15.

  In S13, the file management unit 110h determines whether there is only one other document image Ij instead of a plurality of document images Ij. If there is only one other document image Ij, the process proceeds to S15, and if there are a plurality of other document images Ij, the process proceeds to S14.

  In S14, the file name assigning unit 110c assigns a file name to the document image Ik according to the page information extracted from the document image Ik. For example, if the title information extracted from the manuscript image Ik is “Literature University Complete Collection” and the page number information is “50”, “Literature University Complete Collection 50” is assigned as the file name of the manuscript image Ik. The total number of pages may also be given. For example, if n = 100, “literature complete works 50/100” is assigned as the file name of the document image Ik. From this file name, you can see at a glance how many pages of which document the scanned document is.

  In S15, the file name assigning unit 110c assigns a newly generated serial number for each of the document image Ik and the other document image Ij as a file name, and stores it in a predetermined folder. The sequential number assignment order is the order of serial numbers assigned previously. As a result, serial numbers can be assigned to document images from which titles have not been extracted.

  In addition, the method and program which make CPU11 perform above-mentioned step S1-15 are also contained in this invention.
