  FIG. 1 is a block diagram illustrating a configuration example of an electronic document processing apparatus 10 according to an embodiment of the present invention. The electronic document processing apparatus 10 processes the electronic document stored in the document storage unit 20. The document storage unit 20 is a storage device that stores an electronic document. The document storage unit 20 may be included in the electronic document processing apparatus 10 or may be included in another information processing apparatus connected to the electronic document processing apparatus 10 via a network. The electronic document stored in the document storage unit 20 includes, for example, text data and image data. Further, in this electronic document, a temporary image such as an empty image may be arranged at a position where an image is to be arranged.

  FIG. 2 is a diagram schematically illustrating an example of an electronic document stored in the document storage unit 20. FIG. 2 shows one page included in the electronic document 50 as an example. With reference to FIG. 2, the electronic document 50 includes a temporary image 502. The temporary image 502 is an object temporarily arranged at a position where entity data such as an image is to be arranged. The temporary image 502 is replaced with the entity data when the entity data such as an image to be arranged later becomes available. Here, as the entity data to be replaced with the temporary image 502, for example, an image such as a figure or a photo, a table, a mathematical expression object, or the like can be cited. In the following description, the term “image” refers not only to images such as general figures and photographs, but also to objects such as mathematical formulas and tables that can be inserted into an electronic document, and objects that are different from ordinary text data. .

  The temporary image 502 is arranged at a position where an image is scheduled to be arranged later on the page of the electronic document 50. Further, the size of the temporary image 502 is set to the same size as the size of an image that is scheduled to be placed at that position later. The temporary image 502 may be, for example, a blank image (blank image) that does not have substantial data content.

  The electronic document 50 is created by a user using software for creating and editing an electronic document (hereinafter referred to as “electronic document creation software”) such as a word processor. For example, in creating the electronic document 50, the user temporarily places a blank image of a desired size at a desired position (a position where an image is to be placed later) on the electronic document 50 by an operation using the electronic document creation software. Insert as an image. When the user performs an operation for inserting a temporary image, the electronic document creation software gives a unique identifier in the electronic document 50 to the temporary image. As a result of the temporary image insertion operation by the user, the electronic document 50 includes, for each temporary image, an identifier thereof and arrangement information indicating the position and size in the electronic document 50.

  Further, the electronic document creation software may have a function of accepting setting of identification information of a temporary image by a user. In this case, for example, the user can set the name of the image scheduled to be arranged at the position of the temporary image as identification information of the temporary image. An electronic document created using such electronic document creation software includes a temporary image and identification information set by the user regarding the temporary image. For example, when the image scheduled to be placed at the position of the temporary image is a figure, the user sets a figure number and a figure name for the temporary image, and as a result, the electronic document 50 is stored in the temporary image and the user. The set figure number and figure name are included.

  In addition, the electronic document creation software may have a function of setting a link that enables reference to an image from a specific character string in the electronic document 50. For example, the electronic document creation software receives an instruction to specify a character string in the electronic document 50 and a reference destination image in the electronic document 50, and refers to the reference destination image specified from the specified character string. Set possible information (link). When the electronic document 50 includes such a link setting, for example, when the electronic document 50 is displayed by software for displaying the electronic document on a display device, the user inputs a character string with the link set by a mouse or the like. When specified using the device, a page including an image set as a reference destination of the character string is displayed. In the electronic document 50, for example, for a character string representing identification information (a figure number, a figure name, etc.) of a temporary image set by a user, a link that sets the temporary image as a reference destination is set. When the temporary image is replaced with an actual image, it is possible to refer to the replaced image from the character string set with the link.

  Referring to FIG. 1 again, the electronic document processing apparatus 10 includes a temporary image information extraction unit 100, an extraction information DB (database) 110, a display processing unit 120, a display unit 130, and an allocation processing unit 140.

  The temporary image information extraction unit 100 performs processing for extracting information related to the temporary image from the electronic document 50. The temporary image information extraction unit 100 includes a basic information extraction unit 102 and an accompanying information extraction unit 104. The basic information extraction unit 102 obtains, for the temporary image in the electronic document 50, identification information for identifying the temporary image, arrangement information including the position and size of the temporary image in the electronic document 50, and the temporary image. The basic information including the link information set as the reference destination is extracted from the electronic document 50. Further, the basic information extraction unit 102 performs processing for registering the extracted basic information in the extraction information DB 110. The accompanying information extraction unit 104 uses the information extracted by the basic information extraction unit 102 to convert the accompanying information, which is information related to the content of the image scheduled to be arranged at the position of the temporary image in the electronic document 50, to the electronic document. 50, and the process of registering the extracted information in the extraction information DB 110 is performed.

  The extracted information DB 110 is a database that stores information extracted from the electronic document 50 by the temporary image information extracting unit 100. 3 and 4 show examples of data contents of the extraction information DB 110. FIG.

  FIG. 3 shows an example of the contents of data registered in the extraction information DB 110 by the basic information extraction unit 102. One line of information in the table illustrated in FIG. 3 is an information record corresponding to one temporary image included in the electronic document 50. In the example of FIG. 3, the record corresponding to each temporary image includes items of file path name, temporary image identifier, figure number, figure name, link, page, position (X, Y), and size. The file path name indicates the storage position of the electronic document 50 in the document storage unit 20 in which the electronic document 50 including the temporary image corresponding to the record is stored. The temporary image identifier is an identifier for the electronic document processing apparatus 10 to identify a temporary image corresponding to the record, and is an identifier unique within one electronic document 50. The temporary image identifier is, for example, an identifier given by the electronic document creation software when the temporary image is arranged in the electronic document 50. The figure number and the figure name are respectively a number and a name set by the user for the temporary image (an image to be arranged at the position). That is, the figure number and the figure name are identification information of the temporary image set by the user. The item of link represents whether or not the above-described link with the temporary image as a reference destination is set in the electronic document 50. In the example of FIG. 3, “TRUE” is registered as the value of the link item, and “FALSE” is registered when the link is not set. The page represents the page number where the temporary image is arranged in the electronic document 50. The position (X, Y) represents the coordinates of the arrangement position of the temporary image on the page of the electronic document 50 where the temporary image is arranged. In the example of FIG. 3, the position of the temporary image is expressed as the coordinates of the position of the upper left vertex when the shape of the range in which the temporary image is arranged is a rectangle. The size represents the size of the temporary image. In the example of FIG. 3, the size of the temporary image is represented in a format of “(number of horizontal pixels) × (number of vertical pixels)”. The page, position, and size may be registered in a format different from the expression format illustrated in FIG. 3 as long as the content indicates the layout position of the temporary image and the size of the temporary image in the electronic document.

  FIG. 4 shows an example of the contents of data stored in the extraction information DB 110 by the accompanying information extraction unit 104. One row of information in the table illustrated in FIG. 4 indicates an information record corresponding to one temporary image included in the electronic document 50. In the example of FIG. 4, the record corresponding to each temporary image includes items of a file path name, a temporary image identifier, a placeholder name, and accompanying information. Among these, the file path name and the temporary image identifier are as described above. The placeholder name is information used in a process by the placeholder creation unit 122 described later as a placeholder name corresponding to each temporary image. The placeholder name is determined based on identification information set by the user for each temporary image, for example. In the example of FIG. 4, the placeholder name is a character string generated by combining the contents registered in each item of the figure number and figure name in the table illustrated in FIG. 3. The accompanying information is information related to the content of the image scheduled to be arranged at the position of the temporary image. In the example of FIG. 4, a portion determined to refer to each temporary image in text data included in the electronic document 50 is registered as accompanying information. The accompanying information is extracted by the accompanying information extracting unit 104 using the information extracted by the basic information extracting unit 102 for the temporary image.

  In the above, the contents of the data registered in the extraction information DB 110 by the basic information extraction unit 102 and the accompanying information extraction unit 104 have been illustrated and described in two different tables (FIGS. 3 and 4). It is not always necessary to separately manage the data registered by the basic information extraction unit 102 and the accompanying information extraction unit 104 using different data tables. For example, in one data table, items associated with a pair of a file path name and a temporary image identifier are registered in association with a pair of a file path name and a temporary image identifier in the examples of FIGS. May be.

  3 and 4 show only records corresponding to the temporary images included in one electronic document 50 (file path name “C: \ pat \ abc.doc”). Records corresponding to the temporary images included in each of the plurality of electronic documents 50 may be registered.

  Referring to FIG. 1 again, the display processing unit 120 performs a process for displaying a list of information stored in the extracted information DB 110 on the display unit 130. The display processing unit 120 includes a placeholder creation unit 122. The placeholder creation unit 122 generates a placeholder corresponding to each temporary image registered in the extraction information DB 110 and stores the generated placeholder in a storage device (not shown). A placeholder is an object that does not have a substance and can be stored in a folder in a general file system. The name and related information can be set for the placeholder. The display processing unit 120 causes the display unit 130 to display a list of information on the temporary images using the placeholders generated by the placeholder creation unit 122.

  The display unit 130 is a display device that displays information of contents instructed from the display processing unit 120.

  The allocation processing unit 140 performs processing for replacing the temporary image in the electronic document 50 with the designated image. Hereinafter, this replacement process may be referred to as “appropriation process”. Upon receiving an instruction to specify one of the temporary images in the electronic document 50 and an image to be placed at the position of the temporary image, the allocation processing unit 140 receives a record of the extraction information DB 110 corresponding to the temporary image. The arrangement information is acquired from the information, and the designated image is arranged at the position of the temporary image according to the acquired arrangement information.

  Hereinafter, details of processing performed in the electronic document processing apparatus 10 will be described in detail.

  FIG. 5 is a flowchart illustrating an example of a procedure of processing performed by the temporary image information extraction unit 100 and the display processing unit 120. 5, steps S <b> 10 to S <b> 30 are processes by the temporary image information extraction unit 100, and step S <b> 40 is a process by the display processing unit 120.

  For example, the temporary image information extraction unit 100 starts the process of the procedure illustrated in FIG. 5 when the user instructs the start of the process. Hereinafter, in the processing start instruction by the user, information for specifying the electronic document to be processed (hereinafter referred to as “processing target document”) and a placeholder corresponding to each temporary image included in the processing target document are stored. It is assumed that the information for specifying the storage position in the apparatus is included.

  First, in step S10, the temporary image information extraction unit 100 refers to the document storage unit 20 and acquires a processing target document. The processing start instruction by the user includes, for example, the file path name of the document to be processed as information for specifying the document to be processed, and the temporary image information extraction unit 100 acquires the electronic document represented by the file path name from the document storage unit 20. To do.

  Next, in step S20, the basic information extraction unit 102 of the temporary image information extraction unit 100 performs a process of extracting basic information about the temporary image included in the processing target document. FIG. 6 shows an example of a detailed procedure of the basic information extraction process in step S20 of FIG. When the process of step S20 of FIG. 5 is started, the process of the procedure illustrated in FIG. 6 is started.

  With reference to FIG. 6, in step S <b> 202, the basic information extraction unit 102 determines whether or not a temporary image is included in the processing target document. Here, for example, setting information indicating what kind of image is arranged as a temporary image in the processing target document is stored in advance in a storage device (not shown), and the basic information extraction unit 102 stores the setting information. The presence or absence of a temporary image in the document to be processed is determined by referring to it. In this example, this setting information indicates that a blank image is arranged as a temporary image. If the blank image exists in the processing target document, the basic information extraction unit 102 includes the temporary image in the processing target document. It is determined that

  If it is determined in step S202 that the processing target document includes a temporary image, the process proceeds to step S204. If it is determined in step S202 that the processing target document does not include a temporary image, the basic information extraction process ends.

  In step S204, the basic information extraction unit 102 extracts identification information and arrangement information from the processing target document for one of the temporary images detected in step S202. For example, as identification information of the temporary image, the temporary image identifier given to the temporary image by the electronic document creation software, identification information (such as a figure number and a figure name) set by the user for the temporary image, Is extracted. As the arrangement information, for example, the number of pages on which the temporary image is arranged in the electronic document 50, the coordinates representing the position of the temporary image on the page, and the size of the temporary image are extracted. Further, the basic information extraction unit 102 detects the presence / absence of a link set with the temporary image as a reference destination in the processing target document.

  In step S206, the basic information extraction unit 102 stores the information extracted in step S204 in the extraction information DB 110. For example, the basic information extraction unit 102 generates a record corresponding to the temporary image in the extraction information DB 110, and includes the file path name of the processing target document, the temporary image identifier of the temporary image, the figure number, and the figure name in the generated record. Each item of the presence / absence of a link, the page where the temporary image is arranged, the position, and the size is registered.

  In step S208, it is determined whether or not processing has been completed for all temporary images in the processing target document. If it is determined that the processing has been completed for all the temporary images in the processing target document, the basic information extraction processing in FIG. 6 ends. If it is determined in step S208 that processing has not been completed for all temporary images in the processing target document, the process returns to step S204, and basic information extraction processing (step S204) and unprocessed temporary images are performed. Registration processing in the extraction information DB 110 (step S206) is performed.

  When the basic information extraction process illustrated in FIG. 6 ends, the process proceeds to step S30 in FIG. Hereinafter, a case will be described as an example in which data having the contents illustrated in FIG. 3 is registered in the extraction information DB 110 after the basic information extraction process illustrated in FIG. 6 is completed.

  Referring to FIG. 5 again, in step S30, the accompanying information extraction unit 104 performs processing for extracting accompanying information about the temporary image included in the processing target document from the processing target document. FIG. 7 shows an example of a detailed procedure of the accompanying information extraction process in step S30 of FIG. When the process of step S30 in FIG. 5 is started, the process of the procedure illustrated in FIG. 7 is started.

  Referring to FIG. 7, first, in step S302, the accompanying information extraction unit 104 refers to the extraction information DB 110 and acquires one record corresponding to the temporary image included in the processing target document. For example, the accompanying information extraction unit 104 acquires one record registered in the extraction information DB 110 in which the same file path name as the file path name of the processing target document is registered. In this example, one of the five records corresponding to the temporary image identifiers “PH01” to “PH05” in the table of FIG. 3 is acquired in step S302.

  Next, in step S304, the accompanying information extraction unit 104 generates a placeholder name. The placeholder name is generated based on identification information set by the user for the temporary image. For example, the accompanying information extraction unit 104 generates a placeholder name by combining the contents registered in the figure number and figure name items of the record acquired in step S302. For example, referring to FIG. 3, when the record corresponding to the temporary image identifier PH01 is acquired, the value “1” of the item of the figure number is combined with the content “impulse waveform” of the item of the figure name. Using a character or character string (for example, “Figure”, “Fig.”, “Figure”, etc.) set in advance in the document to be processed as a character string representing the character string “Figure 1 Impulse waveform” Generate as placeholder name. For example, when the value of the figure name item of the acquired record is “null (none)”, the placeholder name is generated using only the figure number item. For example, when the records corresponding to the temporary image identifiers PH03 and PH05 in FIG. 3 are acquired, the generated placeholder names are, for example, “FIG. 3” and “FIG. 5”, respectively.

  In step S <b> 306, the accompanying information extraction unit 104 determines whether or not a link with the temporary image as a reference destination is set in the electronic document 50 for the temporary image corresponding to the acquired record. For example, the accompanying information extraction unit 104 determines that the link is set if the value of the link item of the acquired record is “TRUE”, and if the value of the link item is “FALSE”, the link is determined. It is determined that is not set.

  If it is determined in step S306 that a link has been set, the process proceeds to step S320, and the accompanying information extraction unit 104 sets a link that refers to the temporary image corresponding to the acquired record in the processing target document. Get one sentence including the set character string. In the case where there are a plurality of character strings in the electronic document 50 to which a link with the temporary image as a reference destination is set, for example, the character existing in the position closest to the temporary image with reference to the arrangement information of the temporary image. Get a sentence containing a column. After step S320, the process proceeds to step S324.

  If it is determined in step S306 that no link is set, the process proceeds to step S308. In step S308, the accompanying information extraction unit 104 searches the entire processing target document for a keyword based on the figure number. For example, when the value of the figure number item of the acquired record is “1”, the character string preset in the processing target document as the character string representing the figure number and the value “1” of the figure number item A full-text search is performed in the processing target document using a character string (for example, “FIG. 1”, “Fig. 1”, “Figure 1”, etc.) combined with.

  In step S310, it is determined whether or not a keyword based on the figure number has been found in the processing target document as a result of the search in step S308. If a keyword based on the figure number is found, the process proceeds to step S322. If no keyword is found, the process proceeds to step S312.

  In step S312, a character string that is not explicitly specified at the position of the temporary image but is considered to refer to the image (for example, "upper figure" and "lower figure"). Is used as a keyword to search within a predetermined range including the arrangement position of the temporary image in the processing target document. In step S312, for example, the arrangement information of the corresponding temporary image is acquired from the record to be processed, and the page where the temporary image is arranged is searched.

  Next, in step S314, it is determined whether a keyword has been found as a result of the search in step S312. If a keyword is found, the process proceeds to step S322. If no keyword is found, the process proceeds to step S316.

  In step S316, “Null” is registered in the extraction information DB 110 as the accompanying information of the temporary image to be processed. After step S316, the process proceeds to step S318.

  In step S322, the accompanying information extraction unit 104 acquires one sentence including the keyword found by the search in step S308 or the search in step S312. As a result of the search, when a keyword is found at a plurality of locations in the processing target document, for example, one sentence including the keyword at the position closest to the temporary image to be processed is acquired.

  In step S324, the accompanying information extraction unit 104 registers the one sentence acquired in step S320 or step S322 in the record corresponding to the temporary image in the extraction information DB 110 as the accompanying information of the temporary image to be processed. After step S324, the process proceeds to step S318.

  In step S318, it is determined whether all the temporary images in the processing target document have been processed. That is, it is determined whether or not processing has been performed for all records in which the same file path name as that of the processing target document is registered in the extraction information DB 110. If all the temporary images have not been processed, the process returns to step S302, one unprocessed record is selected, and the processes in step S302 and subsequent steps are performed. If all the temporary images have been processed, the accompanying information extraction process illustrated in FIG. 7 ends.

  According to the accompanying information extraction processing illustrated in FIG. 7, for each temporary image included in the electronic document 50, a character string that is considered to refer to the contents of the image scheduled to be arranged at the position of the temporary image is extracted as the accompanying information. Is done. Hereinafter, a case will be described in which the data illustrated in FIG. 4 is registered in the extraction information DB 110 as a result of the accompanying information extraction processing of FIG.

  When the accompanying information extraction process (step S30 in FIG. 5 and FIG. 7) ends, the process in step S40 in FIG. 5 is performed.

  Referring again to FIG. 5, in step S <b> 40, the placeholder creation unit 122 of the display processing unit 120 performs a process of creating placeholders corresponding to the temporary images registered in the extraction information DB 110. The placeholder creation unit 122 stores a placeholder corresponding to each temporary image at a position specified by a user in a storage device (not shown). For example, when the user designates the placeholder to be stored below “Folder A” in a storage device (not shown), as illustrated in FIG. 8, the temporary image identifiers PH01 to PH05 shown in FIGS. Placeholders 40a to 40e corresponding to the temporary images are generated and stored under “folder A”. Also, the placeholder creation unit 122 stores, for example, the contents of the item “placeholder name” registered in the record corresponding to each temporary image in the extraction information DB 110 as the name of the placeholder corresponding to each temporary image. . Further, for example, the placeholder creation unit 122 stores the contents of the “accompanying information” item registered in the record corresponding to each temporary image in the extraction information DB 110 as the related information of the placeholder corresponding to each temporary image.

  When the creation of the placeholder by the placeholder creation unit 122 is finished, the process illustrated in FIG. 5 is finished.

  As described above, as a result of the processing described with reference to FIGS. 5 to 8, the extracted information DB 110 is obtained by associating identification information, arrangement information, and accompanying information of the temporary image with respect to each of the plurality of temporary images included in the electronic document. Registered in Furthermore, a placeholder corresponding to each temporary image is created.

  The display processing unit 120 causes the display unit 130 to display the placeholder created by the placeholder creation unit 122. For example, the display processing unit 120 causes the display unit 130 to display the display screen 30 illustrated in FIG. In the example of FIG. 9, the name of the placeholder corresponding to each temporary image and the accompanying information stored as the related information of the placeholder are displayed in a list in association with each other. The display processing unit 120 displays such a screen 30 on the display unit 130, so that information representing a list of what temporary images are arranged in one electronic document 50 is presented to the user. The

  The mode of the screen displayed on the display unit by the display processing unit 120 is not limited to the mode of the example of the screen 30 in FIG. For example, the display processing unit 120 may display only the placeholder names on the display unit 130 without displaying the accompanying information stored as the placeholder related information. Further, for example, the display processing unit 120 refers to the extraction information DB 110 as necessary, reads out arrangement information (page, position, and size in the example of FIG. 3) of each temporary image, and reads out the arrangement information. May be displayed in association with the name of the placeholder corresponding to each temporary image.

  For example, the user can issue an instruction to associate the temporary image in the electronic document 50 with the actual image to be replaced with the temporary image with reference to the display screen 30 as shown in FIG. For example, when an icon 32 representing image data is displayed on the display unit 130 together with the display screen 30 illustrated in FIG. 9, the user designates the icon 32 using an input device such as a mouse (not shown). By performing an operation (an operation called “drag and drop”) associated with the portion of “FIG. 1 impulse waveform” shown on the display screen 30, the name of “FIG. 1 impulse waveform” is displayed in the electronic document 50. The temporary image corresponding to the placeholder having “” can be instructed to be replaced with the image represented by the icon 32. When such an instruction is performed, the allocation processing unit 140 performs an allocation process for replacing the temporary image in the electronic document 50 with the designated image.

  FIG. 10 is a flowchart illustrating an example of a procedure of processing performed by the allocation processing unit 140. The process illustrated in FIG. 10 is started, for example, when an instruction for associating a temporary image with an image to be replaced with the temporary image is given by the user as described above.

  With reference to FIG. 10, first, in step S <b> 50, the allocation processing unit 140 acquires an image designated to be replaced with a temporary image.

  Next, in step S60, the allocation processing unit 140 refers to the extraction information DB 110, and from the record corresponding to the temporary image designated as the replacement target, the file path name of the electronic document 50 including the temporary image and the temporary image. The arrangement information (number of pages, position, size) is acquired.

  In step S70, the temporary image is deleted from the electronic document 50 having the acquired file path name, and the image acquired in step S50 is inserted instead. At this time, the acquired image is inserted into the electronic document 50 according to the number of pages, the position, and the size included in the layout information acquired for the temporary image.

  In step S80, the allocation processing unit 140 deletes the record corresponding to the temporary image that is the target of the allocation processing in step S70 from the extraction information DB 110. Furthermore, the allocation processing unit 140 deletes a placeholder corresponding to the temporary image that is the target of the allocation processing from a storage device (not shown). After step S80, the allocation process ends.

  When the allocation process illustrated in FIG. 10 is completed, the designated image is inserted into the electronic document 50 at the position where the temporary image targeted for the allocation process has been arranged. FIG. 11 shows an example of the electronic document 50 as a result of performing the assigning process by designating the image “Impulse.bmp” represented by the icon 32 of FIG. 9 for the temporary image corresponding to “FIG. 1 impulse waveform”. . Referring to FIG. 11, the designated image “Impulse.bmp” is arranged at a position 504 where the temporary image was arranged before the allocation process (the position of the temporary image 502 in FIG. 2).

  In the allocation process, if the aspect ratio (aspect ratio) of the temporary image is different from the aspect ratio of the image specified to be replaced with the temporary image, for example, the specified image is matched with the aspect ratio of the temporary image. The designated image may be arranged at the position of the provisional image after changing the aspect ratio. In another example, the designated image may be enlarged or reduced so as to fit within the size of the temporary image while the aspect ratio of the designated image is fixed. Also, for example, when the difference between the aspect ratio of the temporary image and the aspect ratio of the specified image exceeds a predetermined threshold, information indicating that is displayed, indicating whether the user wants to continue the allocation process. You may be prompted to input instructions. When the user inputs an instruction to continue the allocation process, the allocation processing unit 140 changes the aspect ratio of the specified image in accordance with the aspect ratio of the temporary image, or the aspect ratio of the specified image. The appropriation process is executed after enlarging or reducing the image while fixing the. When the user inputs an instruction not to continue the allocation process, the allocation processing unit 140 ends the process without replacing the image.

  In the allocation process described with reference to FIG. 10, the designated image is inserted into the electronic document 50 at the position where the temporary image is arranged. In another example of the allocation process, the specified image file is duplicated, the placeholder corresponding to the provisional image that is the target of the allocation process is deleted in the storage device, and the placeholder is stored at the position where the placeholder is stored. In the electronic document 50, information indicating the storage position of the image file in the storage device may be inserted into the temporary image layout position. For example, the electronic document 50 designates the storage location of the image file in the electronic document, such as an electronic document described in a markup language such as XML (Extensible Markup Language), HTML (HyperText Markup Language), or TeX. In the case of an electronic document that can display the image by including the description, the description in the electronic document may be rewritten to be a description indicating the storage location of the image file.

  As described above, in the processing of the embodiment described with reference to FIGS. 5 to 10, placeholders corresponding to the temporary images included in the electronic document 50 are created and displayed by the display processing unit 120 using the placeholders. , And processing by the allocation processing unit 140 is performed. In another embodiment, the placeholder creation process (step S40) may be omitted in the process illustrated in FIG. In the case of this example in which no placeholder is created, the display processing unit 120 generates a display screen 30 as illustrated in FIG. 9 using information registered in the extraction information DB 110 as illustrated in FIG. Are displayed on the display unit 130. Also in this example, the user refers to the display screen 30 as shown in FIG. 9 and issues an instruction to associate the temporary image with the replacement target image by, for example, drag and drop processing. Can do. Further, the allocation processing unit 140 can perform the allocation processing illustrated in FIG. 10 according to the instruction.

  In the embodiment described above, all the temporary images included in the electronic document 50 correspond to the figure. However, the electronic document 50 is not limited to the temporary image corresponding to the figure, but includes a mathematical expression or a table. A temporary image corresponding to the object may be included. In this case, for example, in the basic information extraction process, an identifier representing the type of object (such as a diagram, a table, and a mathematical expression) that is replaced with each temporary image is extracted and registered in the record corresponding to the temporary image in the extraction information DB 110. In addition, in the accompanying information extraction process, a search is performed in the processing target document using a keyword (for example, a character string such as “Table 1” or “Formula 1”) corresponding to the type of object corresponding to each temporary image. Thus, the accompanying information of each temporary image is extracted.
