  FIG. 1 is a schematic diagram of the overall structure of the document browsing system 1, and FIG. 2 is a block diagram showing an electrical configuration of the document browsing system. The document browsing system 1 is mainly composed of a document management server (server) 10 and a portable document browsing application terminal (terminal) 20, and a desired document file managed in the server 10 is stored in the terminal 20. It is displayed on the display means 23.

  The server 10 mainly includes a control unit 11, a document management unit 12, a text data acquisition unit 13, a bitmapping unit 14, a coordinate acquisition unit 15, a compression unit 16, and a communication unit 17. . The terminal 20 mainly includes a control unit 21, an input unit 22, a display unit 23, a display control unit 24, and a communication unit 25.

  The control means 11 and 21 control each means of the server 10 and the terminal 20, respectively. In addition, the control means 11 and 21 perform processing performed between each means, processing such as file association.

  The document management unit 12 records and manages a plurality of document files. Further, the document file (see FIG. 3) is recorded in association with the data file (see FIG. 4) in which the data obtained from the document file by the data obtaining unit 13, the bitmapping unit 14, and the coordinate obtaining unit 15 is recorded. ,to manage. The document file and the data file managed by the document management unit 12 are read by the text data acquisition unit 13, the bitmap conversion unit 14, the coordinate acquisition unit 15 and the like as necessary.

  The text data acquisition means 13 includes an area (text area) where characters are written in a display target page (document data) included in the document file, and character string data (text data) written in the text area. ) And get. Hereinafter, a document file composed of only one page. A case where doc (see FIG. 3) is displayed will be described as an example.

  Document file The text area and text data of doc are acquired by the following method, for example. When the document file is read in order from the upper left of the document file, the character string “FUJIFILM Corporation” is first recognized. Next to the character string “FUJIFILM Corporation”, a character string “2006.12.29” and a character string “Fujitaro” are recognized. Since the character strings “FUJIFILM Corporation”, “2006.12.29”, and “Fujitaro” were successively recognized, “FUJIFILM Corporation ¥ r ¥ n2006.12.29 ¥ r ¥ nFujitaro” Is obtained as text data. “¥ r ¥ n” is a character string indicating a line feed.

  At the same time, an area (text 1) in which a character string “FUJIFILM Corporation ¥ r ¥ n2006.12.29 ¥ r ¥ nFujitaro” is displayed is acquired as a text region.

  This process is performed in the document file 1. By performing this operation on the entire doc, as shown in FIG. From the doc, 32 text data and text areas are acquired. As a result, data is entered in each column of “document file”, “text region”, and “text data” in the third and subsequent lines (text 1 to text 23) of the data file shown in FIG. Then, the document file name “1.doc” is entered in the line “document file”, whereby the data shown in FIG. doc.

  The bitmapping means 14 recognizes the entire desired page (whole) of the document file and an area including all the text areas acquired by the text data acquisition means 13 (text inclusion area), and each of them as bitmap format data. Record in the document management means 12. Document file The entire bitmap format data created from the doc is named “document file 1 whole.bmp”, and the bitmap format data in the text inclusion area is called “document file 1 text inclusion area.bmp”. By giving a name, the document file 1. associated with doc. In this embodiment, the bitmap format is adopted. However, the bitmap format is not necessary as long as it can be recorded as an image file. In addition, it is not always necessary to create bitmap data for the entire and text inclusion area, and it is sufficient to create bitmap data for at least the area (text inclusion area in FIG. 3) to be displayed on the display means.

  Further, the bitmapping means 14 enlarges or reduces the created bitmap data of the whole or text inclusion area based on the resolution of the display means 23 as necessary. That is, when data indicating the resolution of the display unit 23 is input from the communication unit 17 (described later), the bitmap format of the text inclusion region is set so that the entire text inclusion region becomes the maximum size that can be displayed on the display unit 23. Are enlarged or reduced.

  The coordinate acquisition means 15 acquires the coordinates of each text area acquired by the text data acquisition means 13 and the coordinates of the whole and text inclusion areas bitmapped by the bitmapping means 14 and stores them in the data file. Record. The document file is divided into a plurality of areas, and coordinates are given to each area. In the case of FIG. 3, the upper left area in the document file is given coordinates (0, 0), and the lower right area is given coordinates (400, 600). The coordinate acquisition means 15 acquires the coordinates given to the coordinates of the uppermost left region (start point) and the lowermost right (end point) of the entire, text inclusion region, and all text regions, and the start point And the coordinates of the end point are entered in the column “text area coordinates” of the data file.

  As a result, the text area and text data acquired by the text data acquisition means 13, the entire bitmap format data and text inclusion area data created by the bitmapping means 14, and the coordinate acquisition means 15 are acquired. The coordinate data of each area is associated.

  The compression unit 16 compresses the bitmap format data of the text inclusion region created and enlarged or reduced by the bitmap unit 14.

  The communication means 17 includes the text data of the text area acquired by the text data acquisition means 13, the coordinate data of the text area and the text inclusion area acquired by the coordinate acquisition means 15, and the text inclusion area compressed by the compression means 16. Are output to the terminal 20. In addition, the communication unit 17 acquires the resolution data of the display unit 23 output from the terminal 20 and outputs the data to the bitmapping unit 14.

  The input means 22 includes a numeric keypad, a cross key (not shown), etc. exposed on the surface of the casing of the terminal 20. The operator uses the user interface (UI) displayed on the display means 23 (described later) to select the text area marked by the display control means 24 (described later). The input means 22 inputs to the display control means 24 (described later) which text area is the text area selected by the operator.

  As shown in FIG. 5, the display means 23 is mainly composed of a bitmap display area 23a and a text data display area 23b. The bitmap display area 23a displays the data in the bitmap format of the text inclusion area output from the display control means 24 (described later), and the text data display area 23b is the text input as selected by the input means 22 The text data output from the display control means 24 (described later), which is the text data of the area, is displayed.

  The display control means 24 outputs the data in the bitmap format of the text inclusion area input from the communication means 25 (described later) to the bitmap display area 23a. Further, the display control unit 24 performs marking on all the text regions based on the text inclusion region and the coordinate data of each text region input from the communication unit 25 (described later). The marking is performed by a method of enclosing each text area with a frame or displaying a highlight for each text area (see FIG. 5).

  Further, when it is inputted from the input means 22 that the text area has been selected, the display control means 24 displays the selected text area separately from the unselected text area. The selected text area is displayed by a method of displaying another color highlight in a text area surrounded by a frame or a text area where a highlight is displayed.

  The communication unit 25 acquires text data of the text area output from the server 10, coordinate data of the text area and the text inclusion area, and bitmap-format data of the compressed text inclusion area. Further, the communication unit 25 outputs the resolution data of the display unit 23 to the server 10.

  Next, a process in which the document browsing system 1 configured as described above displays the document data on the display means 23 will be described with reference to FIG.

  First, a document file created by another device such as a personal computer is acquired and recorded in the document management means 12 (step S1).

  A desired document file is read from the document management unit 12 and input to the text data acquisition unit 13, and the text data acquisition unit 13 extracts all text regions included in the document file (step S2).

  For the text region extracted in step S2, text data is acquired by the text data acquisition unit 13, and coordinate data is acquired by the coordinate acquisition unit 15 (step S3). The text data and coordinate data acquired in step S3 are written in the data file and recorded in the document management means 12.

  Based on the text area extracted in step S2 and the coordinate data acquired in step S3, the text inclusion area is recognized by the bitmapping means 14 and converted into bitmap format data (step S4). Data in the bitmap format of the text inclusion area is recorded in the document management unit 12.

  When the preparation stage (steps S1 to S4) is completed, communication processing (steps S5 to S10) is performed.

  The resolution data of the display unit 23 is output from the communication unit 25 of the terminal 20 (step S5) and acquired by the communication unit 17 of the server 10 (step S6). The resolution data acquired by the communication unit 17 is input to the bitmapping unit 14, and the bitmapping unit 14 enlarges or reduces the bitmap data in the text inclusion area according to the input resolution ( Adjusted) (step S7).

  In order to facilitate communication, the bitmap-format data of the text inclusion area enlarged or reduced in step S7 is compressed (step S8). The bitmap format data of the text inclusion region compressed in step S8 and the text data and coordinate data of the text region extracted in step S2 are output from the communication means 17 of the server 10 (step S9), and the terminal 20 Is acquired by the communication means 25 (step S10).

  When the communication processing (steps S5 to S10) is completed, display processing (steps S11 to S15) on the terminal 20 is performed.

  The bitmap-format data of the compressed text inclusion area acquired in step S10 and the text data and coordinate data of the text area are input to the display control means 24, and the display control means 24 selects the compressed text inclusion area. By decompressing the bitmap format data and outputting it to the display means 23, the bitmap format data of the text inclusion area is displayed in the bitmap display area 23a of the display means 23 (step S11). Since the bitmap format data of the text inclusion area is enlarged or reduced in accordance with the resolution of the display means 23, the entire text inclusion area can be displayed on the display means 23 with the maximum size. Further, by displaying the entire document, it is possible to easily determine the type and rough content of the displayed document.

  In the display control means 24, marking is displayed in the text area of the text inclusion area displayed in the bitmap display area 23a based on the input text area and coordinate data (step S12). Thereby, the operator can select the text area via the UI. When a desired text area is selected by the operator, the selection result is input to the display control means 24 by the input means 22.

  It is determined whether or not a text region selection result has been input by the input means 22 (step S13). If no text area selection result is input (NO in step S13), the process is terminated.

  A case where text 4 (see FIG. 3) is selected by the operator will be described as an example. When the selection result of the text area is input (YES in step S13), it is selected by the operator based on the coordinate data ((50, 150) to (250, 160)) of the text area input to the display control means 24. The text data of the selected text area (estimated as follows for the requested work) is acquired (step S14).

  By outputting the text data from the display control means 24 to the display means 23, as shown in FIG. 5, the text data “Estimate as requested for the work requested” is as follows. The data is displayed in the data display area 23b (step S15). Thereby, the character string desired by the operator is enlarged and displayed, and the contents of the document can be confirmed while confirming the entire image of the document. Even when the size of the display means is small, it is possible to prevent a problem that the contents are not known because the characters are small, and even when the size of the display means is small, the visibility of document browsing can be improved.

  In the present embodiment, since the text inclusion area has a horizontally long shape as shown in FIG. 5, as shown in FIG. 7A, a space is generated above and below the bitmap display area 23a. The bitmap format data of the text inclusion area is displayed in the bitmap display area 23a. If the text inclusion area has a vertically long shape, as shown in FIG. The bitmap data in the text inclusion area is displayed in the bitmap display area 23a in such a way that a space is left and right.

  In this embodiment, the text data in the text area selected by the operator is displayed in the text data display area 23b provided below the bitmap display area 23a. Not exclusively. For example, as shown in FIG. 8, the text data display area may not be provided, and the text data may be enlarged and displayed so as to overlap the text inclusion area.

  In the present embodiment, the process of extracting the text area, text data, coordinate data, bitmap format data, etc. from the document data is performed at the preparation stage of the process of displaying the document data on the display means 23 (see FIG. 6). However, the extraction process is performed on all document files in advance, the extracted data and the document file are associated with each other and registered in the document management unit 12, and the display process is performed from step S5 of FIG. You may do it.

  In the present embodiment, the bitmap data of the text inclusion area is enlarged or reduced in the server 10 in accordance with the resolution of the display unit 23. However, the processing may be performed by the terminal 20. . In this case, the compressed data including the bitmapped data of the text inclusion area may be decompressed by the display control unit 24 and enlarged or reduced in accordance with the resolution of the display unit and then output to the display unit 23.
