  The present invention relates to a data conversion device that receives the output data from an information processing device that holds the output data and transmits the output data to an output processing device that performs output processing based on the output data, a method for controlling the data conversion device, and data conversion Apparatus control program, recording medium recording data conversion apparatus control program, output processing apparatus, output processing apparatus control method, output processing apparatus control program, output processing apparatus control program recording medium, and data transfer About the system.

  In recent years, it has become possible to browse information on the Internet or information such as e-mail from outside while using a terminal device such as a mobile phone. In addition, when browsing information from outside, the functions and / or display capabilities of applications and the like of both devices may differ between the information providing device and the terminal device that receives the information. .

  For example, an example of data transmission / reception between devices having different functions and / or display capabilities includes data transfer between a personal computer (PC) and a terminal device described below. That is, the document data created on the PC or the like is transmitted to the terminal device through a wireless network or the like as an attached file of an electronic mail. Then, the terminal device displays the received document data and enables browsing.

  By the way, for example, document data transmitted / received between devices having different functions and / or display capabilities includes documents such as posters and advertisement designs as well as standard documents such as business reports and price estimates. . Such document data is desired to be displayed on a device that has received the document data in a layout or design as intended by the creator.

  Therefore, for example, in Patent Document 1 and Patent Document 2, there is a technique for performing data transmission / reception between devices having different functions and / or display capabilities as described above, and enabling data to be displayed on a receiving device. It is disclosed.

  More specifically, in Japanese Patent Application Laid-Open No. H10-228867, the receiving terminal that is the data receiving destination determines the capability that can be handled, such as the file size, the maximum pixel size, and the maximum number of colors, and the data is in a format that matches the capability. An information processing apparatus for converting the information is disclosed. On the other hand, Patent Document 2 discloses an information providing apparatus that divides transmission information for each format, converts the divided data so as to conform to the format of the transmission destination, and provides the transmission destination with the converted data.

In addition, devices that are portable, such as the terminal devices described above, and that receive information while away from home are designed to be “portable”, so a large display area for displaying received data is secured. Can not do it. For this reason, when the received information is fine and complicated information, the browsing of the information is limited. Therefore, it is preferable that this information received by the terminal device can be printed while maintaining a desired layout and design even in a printing device, for example.

The storage unit 103 also temporarily stores document data (or compressed document data) 114 received by the transmission / reception unit 102. The storage unit 103 also stores font information 113 that is referred to in order to determine the font of text data included in the document data to be transmitted.

  The attribute information storage unit 112 is a readable / writable recording medium, and stores, for example, attribute information 115 as shown in FIG. The storage unit 103 and the attribute information storage unit 112 may be physically provided separately or may be provided integrally.

  The said conversion control part 101 is comprised from CPU etc., for example, and performs various control of each part with which the conversion server 1 is provided. The conversion control unit 101 includes, as functional blocks, a document data analysis unit 104, a text analysis unit 105, a graphics analysis unit 106, an image processing unit 107, a layout information conversion unit 108, a document data generation unit 109, a document data management unit 111, And a compression unit 110.

  The document data analysis unit 104 analyzes document data (compressed document data) 114 received through the gateway 3a. The document data analysis unit 104, based on the received document data 114, text data including character strings, graphics data including graphics such as circles and rectangles, image data including images, and the text data and graphics data. And layout information (location information), which is localization information indicating the layout in the document data, for each of the image data.

  Then, the document data analysis unit 104 lays out the extracted text data in the text analysis unit 105, the extracted graphics data in the graphics analysis unit 106, the extracted image data in the image processing unit 107, and the extracted layout information. Each is transmitted to the information converter 108.

  More specifically, for example, it is assumed that the conversion server 1 receives data of a document 1001a including a text portion, a graphic portion, and an image portion as shown in FIG. . In this case, the document data analysis unit 104 extracts text data, graphics data, image data, and layout information of these data from this data. FIG. 3 is a diagram showing an example of a document 1001 according to this embodiment.

  For example, when the document data analysis unit 104 extracts text data from the received document data, the display based on the extracted text data is a text 1002 shown in FIG. When the document data analysis unit 104 extracts image data from the received document data, the display based on the extracted image data is, for example, an image 1003 shown in FIG. 4B. The image 1003 is composed of a raster-format still image or moving image. The image 1003 is expressed in units of pixels, and the vertical and horizontal pixel numbers of the image and the color information of each pixel are recorded as information expressing the image 1003.

  When the document data analysis unit 104 extracts a graphics data portion from the received document data 114, the display based on the extracted graphics data is, for example, a graphics 1004 shown in FIG. Become.

  FIG. 4 is a diagram showing an example of a display state based on the data extracted by the document data analysis unit 104 included in the conversion control unit 101 according to the present embodiment, and FIG. FIG. 6B is a diagram showing an example of text 1002 displayed based on the text data, FIG. 5B is a diagram showing an example of image 1003 displayed based on the extracted image data, and FIG. It is a figure which shows an example of the graphics 1004 displayed based on the extracted graphics data.

  When the text analysis unit 105 receives the text data extracted by the document data analysis unit 104, the text analysis unit 105 further analyzes the text data. That is, the text analysis unit 105 analyzes the text data into data including text content itself, data including font design, character decoration, and the like.

  More specifically, for example, as shown in FIG. 5, the text analysis unit 105 further extracts a text portion 1101 from the text 1002 extracted by the document data analysis unit 104. In this case, the text analysis unit 105 uses the extracted text portion 1101 as components of the text portion 1101, that is, the text content 1112, the character size 1113, the character design name 1114, and the character design (font ) It is classified into 1111. FIG. 5 is a diagram illustrating an example of a result obtained by further analyzing the text 1003 by the text analysis unit 105 included in the conversion control unit 101 according to the present embodiment.

  Further, the text analysis unit 105 refers to the attribute information 115, and among the classified constituent elements, the constituent elements necessary for performing the same display as the display device 2a on the display device 2b, Categorize as non-component. In the present embodiment, as described above, based on the attribute information 115 acquired from the display device 2b that is the transmission destination of the document data, it is transmitted to the display device 2b in order to display it in the same display state as the display device 2a. A component determined to be necessary is referred to as basic data. Then, the text analysis unit 105 converts the component classified as the basic data into an expression format as a simple drawing command with a smaller data amount.

  For example, the text analysis unit 105 converts the character size 1113, the character design name 1114, and the like into the descriptions shown in the 007th line, the 013th line, and the 030th line shown in FIG. Or the description shown in lines 010 to 011 and lines 012 to 014. Note that the above-described conversion regarding the basic text data and correction data by the text analysis unit 105 may not be necessary depending on an output destination device that outputs the text data.

  As described above, the text analysis unit 105 transmits to the document data generation unit 109 data representing the components classified as basic text data as simple drawing commands as described above.

  In addition, when the processing device for the document data 114 is a printing device, the text analysis unit 105 also generates, for example, the following correction data according to the performance of the printing device 4 and the like. That is, for example, when an instruction is received from the printing apparatus 4 that font data for printing out the characters “sentence”, “character”, and “column” in the Mincho style is not held, The information indicating this typeface is created by vector expression so that “sentence”, “character”, and “column” can be printed out. Then, the created information is transmitted as correction data to the printing apparatus 4 so that “text”, “character”, and “column” can be printed out in the Mincho style. As described above, the data prepared so that the same display as the display device 2a on the transmission side of the document data can be printed out according to the performance of the printing device 4 on the reception side of the document data is the correction data. Called. That is, the correction data is data that is newly required when the printing apparatus 4 performs a printing process based on the transmission data via the display apparatus 2b that performs display based on the received document data. In other words, the correction data is data that is the difference between the drawing data 415 required for display on the display device 2b and the printing data required for printing on the printing device 4. .

  When the graphics analysis unit 106 receives the graphics data extracted by the document data analysis unit 104, the graphics analysis unit 106 further analyzes the graphics data. That is, the graphics analysis unit 106 further analyzes the graphics data, for example, data including basic drawing commands such as lines, rectangles, circles, ellipses, and free lines, and information on tone effects such as gradation, transparency, and embossing. Into data that contains

Then, the graphics analysis unit 106 further refers to the attribute information 115 and classifies the classified components into basic data and non-basic data. The graphics analysis unit 106 converts the components classified as the basic data into an expression format as a simple drawing command with a smaller data amount. For example, the graphics analysis unit 106 converts the expression format of components such as the basic rendering command 1141 and the color tone effect information 1142 classified as basic data into a vector format. The vector format is a format for representing an image as a set of graphics, and records the coordinates, size, direction, and the like of each graphic.

  For example, when the attribute information 115 includes information indicating that gradation display can be performed as a color tone effect that can be displayed by the display device 2b, the graphics analysis unit 106 can be described as follows. That is, for example, “a circle with a radius of 2 and a line color of 100% red” are set for a portion not subjected to gradation processing. On the other hand, for the part to be subjected to gradation processing, “the fill color is a gradation of red and white, the beginning of the gradation processing is 100% red and the end point is 20% white”, “the direction of gradation processing is the top of the graphics From the bottom. "

  In addition, when the processing apparatus for the document data 114 is the printing apparatus 4, the graphics analysis unit 106 generates correction data such as the following according to the performance of the printing apparatus 4, for example. That is, when an instruction that gradation processing cannot be performed from the printing apparatus 4 is received, the printing apparatus 4 uses, as correction data, data created by changing part of the description content of the graphic data as follows, for example. Send to. The printing apparatus 4 can perform printing with an expression that can realize a color tone effect equivalent to gradation processing.

  That is, the graphics analysis unit 106 describes the drawing command as “a circle with a radius of 2 and a line color of 100% red” in a portion where gradation processing is not performed. On the other hand, for the portion subjected to the gradation process, the graphics analysis unit 106 “length 0.5, width 0.1 line, line color 100% red”, “length 0.51, width 0.1 line, line color red 99%, white 1% ", ..." length 0.5, width 0.1 line, line color white 100% "," the direction of the gradual change in color is “From top to bottom”.

  FIG. 6 shows an example of the display of the graphics 1004 extracted from the text 1002, FIG. 6A shows an example of the display of the graphics 1004, and FIG. 6B shows the graphics. An example of the display of the basic rendering command 1141 extracted from the graphics data for displaying 1004 and the color tone effect information 1142 extracted from the graphics data of the graphics 1004 is shown.

  When the image processing unit 107 receives the image data extracted by the document data analysis unit 104, the image processing unit 107 performs a reduction process of the image data.

For example, if the compressed image 1131 based on the compressed image data is displayed, the image is displayed as shown in FIG.

  The image processing unit 107 transmits basic data obtained as a result of analysis with reference to the attribute information 115 to the document data generation unit 109. For example, when compressed image data can be used as basic data, the compressed image data is transmitted to the document data generation unit 109.

  When image data generated by the image processing unit 107 and subjected to compression processing is used as basic data, the basic data to be transmitted may include the following information as necessary. For example, in the case where basic data is obtained by changing the size of the image 1003 to 1/2 of the vertical and horizontal directions, information for instructing to display the image 1131 in double the vertical and horizontal directions is included.

  In addition, when the processing based on the document data 114 is performed by the printing apparatus 4, the image processing unit 107 outputs, for example, correction data to the document data 114 so that the printing apparatus 4 can output image data with high reproducibility. It also holds the original image data included. That is, when receiving an instruction from the printing apparatus 4 to perform printing based on the image data, the image processing unit 107 transmits the original image data to the printing apparatus 4 as correction data.

The printing performance information stored in the printing device performance information storage unit 410 may be stored in advance when the printing device 4 is manufactured, or may be input by operating the input unit 403 by the user of the printing device 4. The configuration may be stored in the performance information storage unit 410.

  The print output unit 413 performs print output on a sheet based on a print processing language that is a processing result of a print language conversion unit 412 described later in accordance with an instruction from the print control unit 401.

  The print control unit 401 executes various controls of each unit included in the printing apparatus 4 and can be realized by, for example, a CPU. The print control unit 401 includes a compressed document file decompression unit 405, a basic document data analysis unit 406, a corrected document data analysis unit 407, a print drawing unit 408, a correction information synthesis unit 411, and a print language conversion unit 412 as functional blocks. Prepare.

The compressed document file decompressing unit 405 decompresses the reversibly compressed converted document data 214 received from the display device 2b, that is, basic document data or corrected document data.
The compressed document file decompression unit 405 reads the converted document data 214 from the printing device storage unit 404 and decompresses the converted document data 214. The compressed document file decompression unit 405 transmits basic document data of the decompressed converted document data 214 to the basic document data analysis unit 406, and transmits corrected document data to the corrected document data analysis unit 407.

  The basic document data analysis unit 406 decodes encoded basic document data in the converted document data 214 received from the compressed document file decompression unit 405. The basic document data analysis unit 406 transmits the decrypted basic document data to the correction information synthesis unit 411.

  The corrected document data analysis unit 407 decodes and analyzes the encoded corrected document data in the converted document data 214 received from the compressed document file decompression unit 405. Then, the corrected document data analysis unit 407 transmits the analysis result to the print drawing unit 408.

  The correction information combining unit 411 generates converted document data, that is, correction information combined document data 415 to which correction information at the time of drawing processing or printing processing is added based on the decoded basic document data and corrected document data. is there. The correction information composition unit 411 temporarily stores the generated correction information composition document data 415 in the printing apparatus storage unit 404.

  The layout analysis unit 416 extracts and analyzes layout information from the correction information synthesis document data 415 generated by the correction information synthesis unit 411 for drawing processing by the print drawing unit 408 described later. The layout analysis unit 416 transmits the analyzed result to the print drawing unit 408.

  When image data is encoded and included as a character string in the correction information composite document data 415 used for the drawing process or the printing process, the image decoding unit 417 performs a decoding process on the image data. The result of the decryption process is transmitted to the print drawing unit 408.

  The print drawing unit 408 performs drawing on the printing device display unit 409 based on the layout information received from the layout analysis unit 416 and the printing performance information 414 stored in the printing device performance information storage unit 410.

  The print language conversion unit 412 converts the correction information composite document data 415 into a format that can be printed by the print output unit 413, that is, a print language, in accordance with a print start instruction received by the print input unit 403. Then, the print language conversion unit 412 transmits the converted print language to the print output unit 413 and instructs to execute the printing process.

(Document data conversion process)
Next, a specific example of the conversion process of the document data 114 performed in the conversion server 1 will be described with reference to FIG. FIG. 29 shows an example of various information related to the document data conversion process in the conversion server 1 according to the present embodiment. FIG. 29A shows an example of the attribute information 115, and FIG. ) Is a component included in the text portion, graphics portion, and image portion of the document data 114, data to be transmitted as basic document data, and data to be transmitted as corrected document data from among the components of the document data 114. It is a figure which shows an example.

  For example, it is assumed here that the attribute information 115 stored in the attribute information storage unit 112 has the contents shown in FIG. In other words, the font family that can be handled in the display device 2b is A font (A is an arbitrary font), the font sizes that can be handled are 12 points (pt), 16pt, and 24pt, and the displayable display colors are 256 colors. It is. In addition, the display device 2b does not have a function capable of realizing gradation processing, the color tone expression is solid, the usable image format is PNG, the displayable image size is vertical / horizontal, 200 dots (dot). It is assumed that 200 dots (dots) and 256 colors can be displayed.

  Here, the display device 2b can handle only the A font for the font family of elements included in the document data 114 (A font, B font (both A and B are arbitrary fonts)). Therefore, for “ka” and “na” written in A style, in addition to the description of the font family showing A style, a text rendering command was written to draw “ka” and “na” in A style. Things are classified as basic data.

  On the other hand, with respect to “sentence”, “character”, and “column” written in B style, the description of the font family indicating B style is used as basic data, and “sentence”, “character”, and “column” are drawn in B style. The text rendering commands described in vector typeface are classified as correction data. Further, since the font size of the component included in the document data 114 is 12 pt and the display device 2b can handle this font size, a description indicating the font size is used as basic data.

  In the display device 2b, as shown in FIG. 29B, the display colors correspond to 256 colors, and therefore correspond to the fill colors designated by the document data A, red and white. Therefore, the description of the drawing command including the information indicating the fill color is classified as basic document data. Further, since the display device 2b does not have a function capable of realizing gradation processing as a color tone effect, a gradation drawing command (information for instructing to implement a gradation effect in which the hue decreases by 20% in the upward direction) is basically used. In addition to classifying as data, a description command including a paint drawing instruction for instructing that a display equivalent to the case where gradation processing is performed is classified as correction data.

  Further, the image included in the document data 114 is 600 dots long and 480 dots wide and the image format is PNG. However, in the display device 2b which is the transmission destination of the converted document data 214, the image is 200 dots long and 200 dots wide. Can be displayed. Therefore, data obtained by reducing the image size to 200 dots vertically and 200 dots horizontally according to the attribute information 115 is used as basic data. On the other hand, in the printing process in the printing apparatus 4, original image data that has not been reduced is necessary to output information displayed on the display apparatus 2a with high reproducibility. Therefore, this original also classifies image data as correction data.

  As described above, the conversion server 1 according to the present embodiment, with respect to the document data 114 received from the display device 2a, data to be transmitted to the display device 2b based on the attribute information 115, that is, basic document data, Information for supplementing the basic document data for printing in a state similar to the display state in the display device 2a, that is, the corrected document data can be classified and data to be transmitted can be determined according to the transmission destination.

  For this reason, it is only necessary to transmit only basic document data to the display device 2a, and additional corrected document data to the printing device 4, which reduces the amount of data to be transmitted and shortens the time required to transmit this data. Can be made.

  Next, details of the document data conversion process performed in the conversion server 1 will be described with reference to the flowchart shown in FIG. FIG. 13 is a flowchart showing an example of document data conversion processing in the conversion server 1 according to this embodiment.

  The process shown in the flowchart of FIG. 13 is realized by the conversion control unit 101 included in the conversion server 1 reading and executing the program stored in the storage unit 103.

  First, in the conversion server 1, the transmission / reception unit 102 acquires document data (compressed document data) 114 to be transmitted to the display device 2b from the display device 2a via the gateway 3a (step S11, hereinafter S11). As follows). The conversion server 1 may receive this document data from the display device 2a via the gateway A3a in the form of being attached to an e-mail, or may receive only the document data 114 itself. Also good.

  When the transmission / reception unit 102 receives the document data 114, the transmission / reception unit 102 temporarily stores the received document data 114 in the storage unit 103. As described above, when the document data 114 is acquired, in the conversion server 1, the transmission / reception unit 102 acquires the attribute information 115 from the display device 2b on the receiving side of the document data 114 via the gateway 3b (S12).

  When the document data 114 and the attribute information 115 are acquired in this way, in the conversion server 1, the document data analysis unit 104 reads the document data 114 temporarily stored in the storage unit 103 and performs analysis (S13). That is, the document data analysis unit 104 extracts text data, graphics data, and image data from the document data 114. Further, the document data analysis unit 104 also extracts layout information of each of the text data, graphics data, and image data.

  More specifically, in the analysis process of the document data 114 in the above-described step S13, for example, from the document 1001a shown in FIG. 3, as shown in FIGS. Image data, graphics data of the graphics 1004, and layout information of these data.

  The text data extracted in step S13 is transmitted from the document data analysis unit 104 to the text analysis unit 105. When this text data is received, the text analysis unit 105 reads the attribute information 115 acquired in step S12 from the attribute information storage unit 112, and further analyzes the extracted text data (S14). In addition to the basic data, in order to print the text data with basic data that needs to be transmitted to the display device 2b and the display state of the display device 2a with high reproducibility in the printing process in the printing device 4, further The data is classified into necessary correction data.

  More specifically, for example, as shown in FIG. 5, the text analysis unit 105 includes a text portion 1101 from a text 1002 that is an element constituting the document data 114 extracted by the analysis processing of the document data 114 in step S13 described above. Is extracted. Then, the text analysis unit 105 further extracts the text content 1112, the character size 1113, the character design name 1114, and the character design (font) 1111 from the text portion 1101. Then, the text analysis unit 105 refers to the attribute information 115 and, for example, in the attribute information 115, the display device 2b does not have data corresponding to the character design 1111.

  In such a case, the text analysis unit 105 uses the text information 1112, the character size 1113, the character design name 1114, and the layout information included in the document data 1002 as basic data, and uses the character design 1111 as the basic data. Classify as correction data.

  On the other hand, the graphics data extracted by the analysis process of the document data 114 in step S 13 is transmitted from the document data analysis unit 104 to the graphics analysis unit 106. When the graphics data is received, the graphics analysis unit 106 reads out the attribute information 115 acquired in step S12 from the attribute information storage unit 112, and further analyzes the extracted graphics data (S15). Referring to the attribute information 115 here, for example, it is assumed that the display device 2b does not have functions corresponding to gradation, transparency adjustment, and emboss processing as color tone effects that can be realized. In such a case, the graphics analysis unit 106 refers to this graphics data with reference to the attribute information 115, for example, a basic drawing command for instructing drawing of a line, rectangle, circle, ellipse, or free line, as basic data. As separate. In addition, the graphics analysis unit 106 classifies the prepared data as correction data so that it can be output with a color tone effect equivalent to a tone effect such as gradation, transparency adjustment, and embossing.

  Specifically, as shown in FIG. 6A and FIG. 6B, the graphics analysis unit 106 converts the graphics 1004 extracted by the analysis processing of the document data 114 described above into lines, circles, and free. They are classified into basic drawing commands 1141 such as lines and alternative data that can be output with a color tone effect equivalent to the color tone effect information 1142, for example, gradation processing.

  The basic drawing command 1141 and the tone effect information 1142 are preferably expressed in a vector format, but the present invention is not limited to this. The vector format is a format for expressing an image as a set of graphics, and the coordinates, size, direction, and the like of each graphic can be recorded.

  Further, the image data extracted by the analysis processing of the document data (compressed document data) in step S13 is further compressed and encoded by the image processing unit 107 with reference to the attribute information 115 acquired in step S12, for example. The performed image is classified as basic data, and the extracted original image data is classified as correction data (S16).

  More specifically, for example, as shown in FIGS. 7A and 7B, the image processing unit 107 reduces the number of colors or reduces the size of the extracted image data (image 1003). An image 1131 is generated by performing compression processing to be changed, and data of the image 1131 is output as basic data.

  Further, the image processing unit 107 outputs the extracted image data (image 1003) as correction data as it is.

  Further, the layout information in the document data of the text data, graphics data, and image data extracted in step S13 is transmitted from the document data analysis unit 104 to the layout information conversion unit 108. Then, the layout information conversion unit 108 performs the layout information conversion process based on the received layout information (S17).

  In the document data conversion process (the flowchart shown in FIG. 13), the processes in steps S14 to S17 are performed sequentially. However, the order of the processes in steps S14 to S17 is limited to this. For example, the configuration may be such that step S14, step S16, and step S17 are executed after the process of step S15 is executed. Moreover, you may perform each process of step S14-S17 in parallel.

  Next, in step S18, based on the basic data and correction data obtained from each process of steps S14 to S17, the document data generation unit 109 can associate the basic document data and the corrected document data with each other. Are generated (S18).

  As described above, the document data generation unit 109 generates the basic document data and the corrected document data from each of the basic data and the correction data generated in the processes of steps S13 to S16. Thus, when generating the basic document data and the corrected document data, the image data (image 1003) output as the correction data and the compressed image data (compressed image 1131) output as the basic data are base64. It is preferable that the basic document data and the corrected document data are included in the form converted into a character string by the encoding method.

  Note that the constituent elements included in the basic data and the constituent elements included in the correction data are classified for convenience in order to specifically describe them, and the classification of these constituent elements is not limited to this. Absent.

  As described above, when the document data generation unit 109 generates the basic document data and the corrected document data, the generated basic document data and the corrected document data are transmitted to the compression unit 110.

  Note that the correspondence between the basic document data and the corrected document data may be associated with a file name that is named according to a predetermined rule, or the document data management unit 111 described later uses an ID or the like. It may be attached.

  When the compression unit 110 receives the basic document data and the corrected document data from the document data generation unit 109, the compression unit 110 reversibly compresses the basic document data and the corrected document data (S19). Further, the compression processing method in step S19 can be realized by, for example, a file compression format employing a reversible compression algorithm such as LZH, ZIP, GZIP or the like.

  Further, the compression rate in the compression processing in step S19 may be determined in advance in the conversion server 1, and can be adjusted according to designation from the display device 2a on the document data transmission side. Also good. Or it may be adjustable according to the designation from the gateway 3b.

  Further, the compression rate is determined by the attribute information 115 of the display device 2b such as the screen size stored in the attribute information storage unit 112 or the usable font size, the attribute information set in advance in the conversion server 1, or the data conversion system 100. It may be determined according to attribute information defined based on the communication volume that can be communicated.

  When the compression unit 110 compresses the basic document data and the corrected document data, the compressed basic document data and the corrected document data are transmitted to the document data management unit 111. The document data management unit 111 assigns IDs to these compressed basic document data and corrected document data, and registers them so that a combination of the compressed basic document data and corrected document data can be specified (S20).

  When the document data management unit 111 completes registration of the basic document data and the corrected document data as described above, the basic document data is transmitted to the transmission / reception unit 102 and is output to the display device 2b on the receiving side via the gateway 3b. To instruct. In response to the instruction from the document data management unit 111, the transmission / reception unit 102 outputs the basic document data and the corrected document data to the display device 2b through the gateway 3b (S21).

  By the way, in step S21, the compressed basic data is configured to be transmitted from the transmission / reception unit 102 to the display device 2b on the reception side through the gateway 3b. However, the display device 2a on the transmission side is further transmitted through the gateway 3a. It may be configured so that it can also be transmitted.

(Text analysis processing)
Details of the text data analysis processing performed by the text analysis unit 105 will be described with reference to FIG. FIG. 14 is a flowchart showing an example of text data analysis processing in the conversion server 1 according to the present embodiment.

  When the text analysis unit 105 receives text data to be analyzed from the document data analysis unit 104, the text analysis unit 105 extracts components such as a font design (font family) and a font size for each text part from the text data. (S31). In this way, the text analysis unit 105 classifies the text part and various components included in the text part from the text data.

  Then, the text analysis unit 105 compares the component of the text part extracted in step S31 with the attribute information 115 already acquired in step S12 of FIG. As a result of this comparison, the component of the extracted text part is referred to the attribute information 115 of the display device 2b to determine whether or not an alternative description is necessary to perform the same display as the display device 2a. (S32).

  That is, this alternative description is the correction data described above. That is, it is not particularly necessary when displaying on the display device 2b based on the document data. However, when the document data is printed on the printing device, it is substantially the same as the display based on the document data on the display device 2a. This information is necessary for printing.

  Here, in the component extracted from the text portion of the document data 114, when the text analysis unit 105 determines that an alternative description is necessary ("YES" in S32), the text includes the component that needs the alternative. Is extracted (S33).

  Then, the text analysis unit 105 refers to the font information 113 stored in the storage unit 103 and inquires about the font information of the component that needs this substitution (S34).

  When the font information 113 is acquired from the storage unit 103 in this way, the text analysis unit 105 executes a font conversion process such as converting a font outline into a different expression format such as a vector expression based on this information. (S35). Then, the text analysis unit 105 temporarily stores the data obtained by this conversion processing as correction data in the storage unit 103 (S36).

  After the correction data is generated and temporarily stored, or when the result of determination in step S32 is “NO”, the text analysis unit 105 generates basic data of the text portion for the component extracted in step S31, and stores the storage unit 103. (S37). As described above, the conversion server 1 executes text data analysis processing.

(Graphics analysis processing)
Here, with reference to FIG. 27, the details of the graphics data analysis processing by the graphics analysis unit 106 will be described. FIG. 27 is a flowchart showing an example of an analysis process of graphics data in the conversion server 1 according to this embodiment.

  The graphics analysis unit 106 collects a set of drawing points for expressing the graphics portion from the graphics data to be analyzed, and various types of information included in the graphics portion (for example, the color of the border or the fill color, gradation, or The color tone effect (such as transparency) is extracted as a component (S201).

  Then, the graphics analysis unit 106 compares the components of the graphics portion extracted in step S201 with the attribute information 115 already acquired in step S12 of FIG. As a result of the comparison, it is determined whether or not an alternative description is necessary for performing the same display as the display device 2a in the extracted graphics data component (S202).

  That is, this alternative description is the correction data described above. Here, in the component extracted from the graphics data of the document data 114, when the graphics analysis unit 106 determines that an alternative description is necessary ("YES" in S202), the component that needs to be substituted is selected. The included graphics data is extracted (S203). Then, the graphics analysis unit 106 refers to the color tone effect information 116 stored in the storage unit 103 and inquires about the color tone information of the component that needs to be replaced (S204).

  Here, based on the acquired color tone effect information 116, the graphics analysis unit 106 converts the color tone effect into, for example, a set of different single color lines so that a gradation can be expressed as a result equivalent to the gradation. Suppose you need to convert. In this case, the graphics analysis unit 106 executes a tone effect conversion process for the component that needs to be replaced in the graphics data (S205). Then, the graphics analysis unit 106 temporarily stores the data obtained by this conversion processing as correction data in the storage unit 103 (S206).

  After the correction data is generated and temporarily stored, or when the result of determination in step S202 is “NO”, basic data of graphics data is generated and stored in the storage unit 103 for the components of the graphics data extracted in step S201. Temporarily store (S207). As described above, the conversion server 1 executes the graphics data analysis process.

(Image analysis processing)
As described above, in the image processing unit 107, based on the attribute information 115, the image data compression rate or the vertical / horizontal image size changed is used as the basic data, and the original image (included in the document data before conversion) Original image data) is transmitted to the document data generation unit 109 as correction data.

  More specifically, for example, the information shown in FIG. 28 is described in the attribute information 115 stored in the attribute information storage unit 112. FIG. 28 is a diagram showing an example of attribute information 115 relating to image data. That is, it is assumed that PNG (Portable Network Graphics) is used as the image format for the attribute information 115 regarding the image data, the height and width of the displayable image are 200 dots, and the color of the image is 256 colors.

  Here, the image processing unit 107 sets the image data of the image part included in the document data 114 before conversion within the range of the condition described in the attribute information 115, that is, the range of 200 dots in both the height and width of the image. The image data is reduced so that it can be displayed.

  Then, the image processing unit 107 classifies the image data reduced according to the displayable range of the display device 2b that is the transmission destination of the document data as basic data, and temporarily stores it in the storage unit 103. The image processing unit 107 classifies the original image data as correction data and temporarily stores it in the storage unit 103, which is necessary when the display state by the display device 2a based on the document data 114 is output with high reproducibility in the printing process. Let me.

  Next, description examples of basic document data and corrected document data output from the conversion server 1 will be described with reference to FIGS. FIG. 15 is a diagram illustrating an example of a document 1001b displayed based on document data. FIG. 16 is a diagram showing an example when the basic document data of the document shown in FIG. 15 is expressed in the SVG format. FIG. 17 is a diagram showing an example when the corrected document data of the document shown in FIG. 15 is expressed in the SVG format.

  As shown in FIG. 15, in the conversion server 1 according to the present embodiment, the basic document data is described in the SVG format. Then, as shown in FIG. 15, the conversion server 1 describes not only the contents of text data, graphics data, and image data but also layout information of each data in the basic document data. Further, as shown in FIG. 17, the conversion server 1 according to the present embodiment also describes the corrected document data corresponding to the basic document data in the SVG format.

(Basic document data)
First, a specific description example of basic document data related to the document 1001b will be described with reference to FIGS.

  The description of the basic document data shown in FIG. 16 defines the following contents. That is, between the <desc> </ desc> tags on the 004 line in the portion sandwiched between the tag <g> on the 003 line and the tag </ g> on the 005 line corresponds to this basic document data. It specifies the corrected document data. That is, the description in the 004 line defines that the corrected document data corresponding to the basic document data is “abc_001-append.svgz”. In the description between the <desc> </ desc> tags on the next 005 line, it is defined that the correction content of the corrected document data is a character design and a color tone effect.

  In addition, between the <desc> </ desc> tags on the 004 line, the corrected document data corresponding to the basic document data is indicated by describing the file name of the corrected document data. For example, it may be specified by address information that can be uniquely specified on the Internet, such as a URL. Also, the use of the <desc> tag described above is merely an example, and other tags that represent metadata can also be described.

  Between the <g> </ g> tags sandwiched between the tag <g> on the 007 line and the tag </ g> on the 010 line, the text in the area 1201 shown in FIG. 15 is described. Further, a region 1202 shown in FIG. 15 is described between <g> </ g> tags sandwiched between a tag <g> on the 011 line and a tag </ g> on the 017 line. More specifically, the image data of the tomato image shown in FIG. 15 and the text data sandwiched between the tag <g> on the 013 line and the tag </ g> on the 016 line as a child element of this image data. ("Tomato 98 yen") are mixed and described so as to be distinguishable.

  A region 1203 shown in FIG. 15 is described between <g> </ g> tags sandwiched between a tag <g> on the 018th line and a tag </ g> on the 033th line. That is, graphics data by a free line <path> and a straight line <line> sandwiched between a tag <g> on line 019 and a tag </ g> on line 029, and child elements of this graphics data, Text data sandwiched between the tag <g> on the 030 line and the tag </ g> on the 032 line are described in a mixed manner so as to be distinguishable.

  As described above, in the basic document data format handled by the conversion server 1 according to the present embodiment, text data, image data, and graphics data are described using one type of tag <g>. . In other words, in the portion sandwiched between the tag <g> and the tag </ g>, the text data, the image data, and the graphics data are described including area information that can be distinguished.

  As described above, in the conversion server 1 according to the present embodiment, the basic document data can be described in a simple format, so that complicated processing is not required for the analysis of the basic document data. It can be said that it is suitable for such a display device that requires miniaturization.

  An ID attribute can be assigned to the <g> tag, and the file name assigned to the basic document data and the ID of the <g> tag included in the basic document data are used. The predetermined area in the document data can be specified.

  Furthermore, by applying, for example, a <des> tag that can handle <g> tags and metadata, it is possible to embed the presence / absence of corrected document data, the file name of corrected document data, and correction contents. Therefore, by using metadata in the basic document data, it is possible to specify the corrected document data corresponding to the basic document data and the correction contents described in the corrected document data.

(Corrected document data)
Next, a specific description example of basic document data related to the document 1001b will be described with reference to FIG. In FIG. 17, the corrected document data corresponding to the basic document data is expressed in the SVG format.

  In this embodiment, it is assumed that the printing apparatus 4 has the following functions as a premise. That is, it is assumed that the printing apparatus 4 does not have a character design (font) of “maru Gothic” regarding text data. For this reason, in order to perform a printing process with the same design and layout as the converted document data 114 held by the display device 2a, it is necessary to correct the design of characters included in the text portion.

  Further, it is assumed that the printing apparatus 4 cannot perform processing related to a tone effect called gradation in print output processing. For this reason, in order to perform the printing process with the same design and layout as the converted document data 114 held by the display device 2a, it is necessary to perform correction so as to obtain a color tone effect equivalent to the color tone effect included in the graphics unit. is there.

  Based on the above assumptions, the corrected document data can be described as follows.

  Here, in the description of the corrected document data shown in FIG. 17, the following contents are defined. That is, between the <desc> </ desc> tags on the 004 line in the portion sandwiched between the tag <g> on the 003 line and the tag </ g> on the 005 line corresponds to the corrected document data. Provides basic document data. That is, the description in the 004 line defines that the basic document data corresponding to the corrected document data is “abc — 001.svgz”.

  Also, in the portion sandwiched between the tag <font> on the 007 line and the tag </ font> on the 27th line, the design name “Maru Gothic” used in the area 1202 of the document 1001b is described. . More specifically, in the area 1202, the actual character design of the character string to which the character design is applied is described using a tag <glyph Unicode = “”>.

  In addition, in the portion sandwiched between the tag <font> on the 007 line and the tag </ font> on the 27th line, the design name of the target character is designated by <font-face font-family = “maru gothic”>. specify. Then, the target character is designated by <glyph unicode = "(arbitrary character)">. In this way, it is possible to specify the design name of the character to be corrected included in the basic document data and the association with the character.

  Further, in the portion sandwiched between the tag <radialGradient> on the 28th line and the tag </ radialGradient> on the 031st line, the color tone correction unit data relating to the region 1203 is described. That is, information about gradation, which is a tone effect of the graphics data, is included between <radialGradient> and </ radialGradient>.

  Further, by giving an ID attribute “id =“ gd — 0 ”in the <radialGradient> tag, the association with the graphics data to be corrected included in the basic document data or each element included in the graphics data is indicated. be able to.

  As described above, in the display device 2a that transmits / receives information to / from the conversion server 1, and also in the printing device 4, the information to be transmitted / received can be expressed by text, so the information to be transmitted / received (basic document data and correction document Data) can be reduced, and display processing and printing processing can be executed. The information included in the corrected document data is not limited to the information described above.

  In the conversion server 1 according to the present embodiment, the basic document data and the corrected document data are described in the SVG data format as shown in FIGS. 16 and 17, but the data format is not limited to this. Absent.

  For example, like the layout information shown in FIGS. 26A and 26B, the basic document data and the corrected document data may be expressed as an array of data, or may be expressed as a function and its input value. .

  As described above, the conversion server 1 according to the present embodiment can convert the document data 114 received from the display device 2a into the basic document data expressed in the SVG format described above. For this reason, it is created by various document data creation applications such as Microsoft Word (registered trademark), Microsoft Excel (registered trademark), PDF (Portable Document Format) (registered trademark), and is described in a data format unique to the application. Document data can be converted into a data format independent of this application.

  For this reason, the display device 2b on the receiving side of the document data 114 does not need to prepare various software so as to correspond to various applications. In other words, the display device 2b may be configured to be able to analyze information related to the received document data 114 and to display this information. When the display device 2b is configured in this way, it is possible to display document data in various data formats transmitted from the display device 2a.

  Further, the conversion server 1 can convert the document data 114 received from the display device 2a into the basic document data expressed in the above SVG format. For example, the image data is described in a vector image instead of the bitmap format. be able to.

  In this way, in the conversion server 1, image data to be output to the display device 2b can be described in particular as a vector image. Therefore, the amount of image data to be output to the display device 2b is described in a bitmap format. Compared with the case where it exists, it can reduce greatly. Therefore, document data can be efficiently transmitted to the display device 2b, and the received document data 114 can be smoothly read in the display device 2b.

  Further, the conversion server 1 according to the present embodiment is configured to classify into basic document data and corrected document data based on the attribute information 115 acquired from the attribute information storage unit 112. For this reason, the conversion server 1 can perform display processing that maintains the same layout and design as the original document data on the display device 2b with the minimum amount of data and communication traffic. Can be printed while maintaining the same layout and design as the document data.

  For example, it is assumed that the display device 2b that is the transmission destination of the document data is a device that can display text by “square POP body”. Then, the basic document data of the document 1002 shown in FIG. 5 is transmitted from the conversion server 1 to the display device 2b.

  Under such a premise, conventionally, for example, the content 1112 of text included in the document 1002 shown in FIG. Character size 1113, character design name 1114, character design (font) 1111 for all used characters, color tone information, layout information indicating text localization, etc. need to be output to the destination device was there.

  However, in the conversion server 1 according to the present embodiment, the text analysis unit 105, the graphics analysis unit 106, and the image processing unit 107 refer to the attribute information 115 included in the transmission destination device and convert the document data 114 into basic data. And correction data. The document data generation unit 109 generates basic document data based on the generated basic data.

  Therefore, for example, if the display device 2b that is the transmission destination of the document data of the document 1002 is a device that can handle the square POP body, and already holds the character design 1111 related to the “corner POP body”, the conversion is performed. The server 1 can output by omitting the information indicating the character design 1111. In other words, the conversion server 1 according to the present embodiment maintains the text, graphics, and image layout of the document data in the display device 2b, and the information for preventing the shape and color of the document from being lost. Only necessary information can be selected and output according to the attribute information 115 of the display device 2b that is the data transmission destination.

  Therefore, the conversion server 1 can perform display processing while maintaining almost the same layout and design as the original document data on the display device 2b with a minimum amount of data and communication traffic.

(Display processing)
Next, document data display processing in the display device 2b according to the present embodiment will be described with reference to the flowchart of FIG. FIG. 18 is a flowchart showing an example of document data display processing in the display device 2b according to the present embodiment. Each process shown in this flowchart is realized by the display control unit 201 included in the display device 2b reading and executing a program stored in the storage unit 205.

  First, the transmitting / receiving unit A202 receives the reversibly compressed converted document data 214 (S41). The transmission / reception unit A202 may receive the reversibly compressed converted document data 214 attached to an e-mail, or may receive only the converted document data 214 alone. The transmission / reception unit A202 temporarily stores the received reversibly compressed basic document data in the storage unit 205.

  Here, it is assumed that the received converted document data 214 is only basic document data. That is, when the display device 2b on the receiving side of the converted document data 214 does not have a function of correcting and displaying based on the received converted data, it can be displayed based only on the basic document data.

  When the input unit 204 receives a display instruction based on the basic document data from the user, the input unit 204 notifies the compressed document data expansion unit 206 of the instruction. When receiving the display instruction from the input unit 204, the compressed document data decompression unit 206 reads the converted document data 214 from the storage unit 205 and performs decompression processing (S42).

  The decompression processing method in step S42 is decompression processing for the algorithm applied to the compression processing of the converted document data 214, and examples thereof include lossless compression algorithms such as LZH, ZIP, and GZIP.

  In step S 42, when the compressed document data decompression unit 206 executes decompression processing of the converted document data 214, the decompressed converted document data 214, that is, basic document data is transmitted to the basic document data analysis unit 207.

  The basic document data analysis unit 207 extracts and analyzes the layout information together with text data, graphics data, and image data from the expanded basic document data. Then, the basic document data analysis unit 207 transmits this analysis result to the drawing data generation unit 215. Thus, the display device 2b according to the present embodiment analyzes the converted document data 214 (S43).

  When receiving the basic document data analysis processing result from the basic document data analysis unit 207, the drawing data generation unit 215 reads and acquires the attribute information 115 from the display device attribute information storage unit 210 (S44). As described above, when the drawing data generation unit 215 acquires the attribute information 115, the drawing data 415 is referred to based on the text data, the graphics data, the image data, and the layout information with reference to the attribute information 115. Is generated (S45). As described above, when the drawing data generation unit 215 generates the drawing data 415, the generated drawing data 415 is temporarily stored in the storage unit 205.

  In the drawing data 415 stored in the storage unit 205, when the image data is included as a character string encoded in the basic document data, the image decoding unit 217 performs a decoding process on the image data, The image data after the decoding process is transmitted to the drawing unit 209. The layout information included in the basic document data is analyzed by the layout analysis unit 216 and the analysis result is passed to the drawing unit 209.

  When the drawing unit 209 acquires the drawing data 415 from the storage unit 205 via the layout analysis unit 216 and the image decoding unit 217, the drawing unit 209 controls to perform display based on the drawing data 415. Then, the display unit 211 displays the drawing data 415 in accordance with an instruction from the drawing unit 209 (S46). Note that the order of step S43 and step S44 may be reversed, or may be executed in parallel. When the order of step S43 and step S44 is reversed, the drawing data generation unit 215 has acquired the text data, graphics data, and image data from the basic document data analysis unit 207 in a state where the attribute information 115 has already been acquired. And the layout information is acquired. When step S43 and step S44 are executed in parallel, when the compressed document data decompression unit 206 transmits the decompressed basic document data to the basic document data analysis unit 207, a drawing data generation unit It also instructs 215 to acquire the attribute information 115.

  Note that the display processing in the display device 2b described above is configured to display a document based on the basic document data received from the conversion server. However, in the display device 2b, when the same display as that of the display device 2a is desired, the display device 2b further receives the corrected document data as the converted document data 214, and performs display processing based on these data. It may be configured. In such a configuration, the display device 2b further includes a corrected document data analysis unit 208 between the compressed document data decompression unit 206 and the drawing data generation unit 215, as shown in FIG. FIG. 33 shows another embodiment of the present invention, and is a block diagram showing a main configuration of the display device 2b.

  The corrected document data analysis unit 208 is, for example, encoded data included in the received converted document data (corrected document data) in accordance with an instruction from the compressed document data decompression unit 206, for example, image data, text data, Alternatively, the graphics data is decoded. When the display instruction based on the display data is input via the input unit 204, the corrected document data analysis unit 208 transmits the corrected document data obtained by decoding to the drawing data generation unit 215.

  Hereinafter, a case where the display device 2b displays document data based on the basic document data and the corrected document data will be described with reference to FIGS.

  FIG. 22 is a flowchart showing an example of document data display processing in the display device 2b according to the present embodiment. Each process shown in FIG. 22 is realized by the display control unit 201 included in the display device 2b reading and executing a program stored in the storage unit 205.

  First, it is assumed that the display device 2b has already acquired basic document data as converted document data 214 as shown in FIG. Then, the display device 2b analyzes the text, graphics, and image data included in the basic document data in the same manner as the processing in steps S41 to S44 shown in FIG. The display device 2b acquires the attribute information 115 from the display device attribute information storage unit 210 so that the result analyzed in step S43 and the attribute information 115 acquired in step S44 can be referred to.

  That is, the basic document data analysis unit 207 extracts and analyzes the layout information together with text data, graphics data, and image data from the expanded basic document data. Then, the basic document data analysis unit 207 transmits this analysis result to the drawing data generation unit 215. When the drawing data generation unit 215 receives the analysis result of text data, graphics data, and image data and the layout information of each data from the basic document data analysis unit 207, the drawing data generation unit 215 receives the attribute information from the display device attribute information storage unit 210. 115 is read and acquired (S44).

  Next, in step SA of FIG. 18, processing after step SA shown in FIG. 22 is performed. Specifically, based on the analysis results of text data, graphics data, and image data received by the drawing data generation unit 215 from the basic document data analysis unit 207, whether or not correction processing is necessary for displaying document data. Figure out. That is, the basic document data describes the necessity of correction processing and the corresponding correction document data information, and the drawing data generation unit 215 refers to the described information to determine whether correction processing is necessary. It is possible to grasp sex.

  If the drawing data generation unit 215 needs to perform correction processing, can the display device 2b synthesize and display the basic document data and the corrected document data from the read attribute information 115? It is determined whether or not (S81).

  In the determination in step S81, when the drawing data generation unit 215 determines that the basic document data and the corrected document data can be combined and displayed (“YES” in S81), the drawing unit 209 causes Instructing the display unit 211 causes the display unit 211 to inquire whether or not to perform correction display reflecting the correction document data (S82). Then, the display device 2b prompts the user whether or not to perform correction display by the display by the display unit 211, and waits for input of a correction display instruction.

  On the other hand, as a result of the determination in step S81 described above, when the corrected document data is synthesized and corrected display processing cannot be performed (in the case of “NO” in S81), or the input unit 504 instructs the user not to perform corrected display. Is received (in the case of “NO” in S82), the drawing data 415 is generated based on the analysis results of the text, graphics, and image only according to the analysis result of the basic document data ( S45).

  Here, when an instruction to perform correction display is received from the user (in the case of “YES” in S82), the drawing data generation unit 215 corrects the correction associated with the basic document data already acquired in step S41. Document data is acquired (S83). The corrected document data can be acquired as follows. That is, the transmitting / receiving unit A202 requests the conversion server 1 to transmit the corrected document data corresponding to the basic document data acquired in step S41. When the corrected document data is transmitted from the conversion server 1 in response to this request, the transmission / reception unit A202 temporarily stores the corrected document data in the storage unit 205 in association with the basic document data acquired previously. When the input unit 204 of the display device 2b receives an instruction from the user to perform correction display, the compressed document data decompression unit 206 reads the corrected document data from the storage unit 205.

  When the compressed document data decompression unit 206 acquires the corrected document data, the decompressed compressed document data is decompressed in the same manner as the basic document data (S84). Then, the compressed document data expansion unit 206 transmits the expanded corrected document data to the corrected document data analysis unit 208. When the corrected document data analysis unit 208 receives the expanded corrected document data, it analyzes the text, graphics, and image data included in the corrected document data (S85). Then, the corrected document data analysis unit 208 transmits the result analyzed in step S85 to the drawing data generation unit 215.

  When the drawing data generation unit 215 receives the analysis result of the basic document data from the basic document data analysis unit 207 and the analysis result of the correction document data from the correction document data analysis unit 208, the drawing data generation unit 215 performs a synthesis process of these and performs layout information Update (S86). Then, the drawing data generation unit 215 generates the drawing data 415 based on the processing result obtained by synthesizing the analysis result of the basic document data and the analysis result of the corrected document data and the layout information (S45). The description regarding the subsequent processing is the same as the processing after step S45 shown in FIG.

  As described above, the display device 2b according to the present embodiment can perform display processing including correction using not only basic document data but also corrected document data. The difference between the display example when the display is performed based only on the basic document data and the display example when the above correction is included will be described with reference to FIGS. 23 (a) and 23 (b).

  FIG. 23 shows an example of document data display on the display device 2b according to the present embodiment. FIG. 23A shows an example of display based only on basic document data, and FIG. ) Shows an example of display based on basic document data and corrected document data.

  As shown in FIGS. 23A and 23B, the layout of the text portion, the graphics portion, and the image portion is maintained so as to match in both the document 1001c and the document 1001d. However, in the document 1001c displayed based on the basic document data, the display state of the text portion 1503 is different from the document 1001d displayed by combining the corrected document data.

  That is, it is assumed that the text portion 1503 is designated in the basic document data to be displayed as “Maru Gothic”, but the display device 2b does not have font data corresponding to “Maru Gothic”. For this reason, in the display of the document 1001c based on the basic document data, the text portion 1503a is displayed in a font that can be used in the display device 2b.

  On the other hand, when the document 1001d is displayed by combining the basic document data and the corrected document data, the display device 2b acquires character design information (round Gothic information) as the corrected document data. For this reason, even if the display device 2b does not use round Gothic, as shown in the text portion 1503b of the document 1001d, the character design information acquired as corrected document data is used to The document can be displayed as instructed by the document data.

  In addition, the display state of the graphics portion 1505a is different in the document 1001c compared to the document 1001d. Specifically, since the basic document data does not include information on the color tone effect on the graphics, the graphics portion 1505a in the document 1001c is displayed in white as an alternative color. That is, when the amount of data that can be processed by the display device 2b is small, the basic document data does not include information on the color tone effect of graphics so that the amount of data to be transmitted can be reduced according to the amount of processing.

  On the other hand, in the document 1001d displayed by combining the basic document data and the corrected document data, since the corrected document data includes information on the above-described graphics tone effect, the graphics portion as shown in FIG. 1505b is displayed by reflecting a predetermined color tone effect.

(Print instruction processing)
Next, in the data conversion system 100 according to the present embodiment, FIG. 19 shows a print instruction process in which the display apparatus 2b instructs the printing apparatus 4 to perform a printing process based on the basic document data and the corrected document data. The description will be given with reference.

  FIG. 19 is a flowchart showing an example of the print instruction process of the display device 2b in the data conversion system 100 according to the present embodiment. Each process of the flowchart shown in FIG. 19 can be realized by the display control unit 201 of the display device 2b reading and executing a program from the storage unit 205.

  In the display device 2b, when receiving a print instruction from the printing device 4, the transmission / reception unit A202 requests the conversion server 1 to transmit corrected document data corresponding to the basic document data already acquired. In response to this request, the corrected document data is transmitted from the conversion server 1, and in the display device 2b, the transmission / reception unit A202 acquires the corrected document data (S51). The transmitting / receiving unit A202 stores the acquired corrected document data as converted document data 214 in association with the already acquired basic document data.

  When the corrected document data is acquired from the conversion server 1 in this way, the document data configuration unit 212 reads the converted document data 214 from the storage unit 205 and packages the corresponding basic document data and the corrected document data (S52). .

  The packaging process of the basic document data and the corrected document data can be realized as follows, for example. That is, the document data configuration unit 201 generates an index file 1301 describing the package contents as shown in FIG. Then, the generated index file 1301 associates the basic document data 1302 and the corrected document data 1303 shown in FIG. 20 so that it can be logically processed as a package, that is, a data set. FIG. 20 is a diagram showing an example of an index file 1301 for associating basic document data and corrected document data.

  Of course, the document data configuration unit 212 may employ a reversible compression algorithm such as LZH or ZIP, and package the basic document data and the corrected document data by archiving them. Furthermore, the index file 1301, the basic document data, and the corrected document data may be archived into the basic document data and the corrected document data by using a reversible compression algorithm such as LZH or ZIP.

  Note that the packaging processing method in step S52 is not limited to the above-described method, and the basic document data and the corrected document data need not be physically one piece of data.

  When the basic document data and the corrected document data are packaged, the document data configuration unit 201 outputs the packaged document data (package data) to a transmission memory (not shown) provided in the transmission / reception unit B203 (S53). ). Then, the document data configuration unit 212 instructs the transmission / reception unit B203 to cause the printing apparatus 4 to transmit the package data and also instructs the printing process based on the package data. In response to an instruction from the document data configuration unit 212, the transmission / reception unit B203 reads the package data from the transmission memory and transmits the package data to the printing apparatus 4, and also transmits information instructing the printing process (S54).

  The above is the print instruction process for the printing device 4 in the display device 2b according to the present embodiment. Next, FIG. 21 shows a printing process executed in the printing apparatus 4 based on the basic document data and the corrected document data that are packaged and transmitted as described above via the display device 2b according to the present embodiment. It explains using. FIG. 21 is a flowchart illustrating an example of a printing process in the printing apparatus 4 according to the present embodiment. The processing shown in the flowchart of FIG. 21 can be realized by reading and executing a program stored in the printing device storage unit 404 by the printing control unit 401 included in the printing device 4.

(Printing process)
First, the print transmitting / receiving unit 402 receives packaged basic document data and corrected document data to be printed from the display device 2b (S61). The packaged basic document data and the corrected document data are received by the print transmitting / receiving unit 402 by wireless communication such as infrared or Bluetooth, but the present invention is not limited to this. For example, an SD memory card or a compact flash (registered trademark) card is used. Alternatively, a configuration may be adopted in which reception is performed via a recording medium such as a USB memory stick.

  Then, when receiving the packaged basic document data and the corrected document data from the display device 2b, the print transmission / reception unit 402 once records them in the printing device storage unit 404. Further, the compressed document file decompression unit 405 is instructed to read the received converted document data 214 in accordance with the information indicating the print processing instruction received from the display device 2b.

  The compressed document file decompression unit 405 reads the packaged basic document data and the corrected document data from the printing apparatus storage unit 404 in response to an instruction from the print transmission / reception unit 402, and performs decompression processing of this packaging (S62). . That is, the display device 2b according to the present embodiment packages the basic document data and the corrected document data in association with each other as described above and transmits the packaged data to the printing device 4. Therefore, the compressed document file decompression unit 405 decompresses the packaged basic document data and the corrected document data to separate the basic document data and the corrected document data.

  Note that the decompression process in step S62 is performed according to an algorithm applied to packaging of the converted document data 214 performed in the display device 2b described above, for example. Subsequently, the compressed document file decompression unit 405 performs the decompression process of the basic document data obtained by the decompression process in step S62 (S63) and the decompression process of the corrected document data (S65). The decompression processing in step S63 and step S65 performs processing for the algorithm applied to the compression processing of the basic document data and the corrected document data. For example, when the basic document data and the corrected document data are encoded by the above-described LZH, ZIP, GZIP or the like, the lossless compression algorithm is executed to perform the decompression process. The compressed document file decompression unit 405 transmits the decompressed basic document data to the basic document data analysis unit 406 and the decompressed corrected document data to the correction document data analysis unit 407, respectively.

  The basic document data analysis unit 406 performs analysis processing (S64) on the received basic document data. That is, when basic document data is received from the compressed document file decompression unit 405, the basic document data is analyzed to extract basic data for each of text data, graphics data, image data, and layout information. On the other hand, the corrected document data analysis unit 407 performs an analysis process (S66) on the received corrected document data. That is, when the corrected document data is received from the compressed document file decompression unit 405, the corrected document data is analyzed to extract correction data for each of text data, graphics data, image data, and layout information.

  Subsequently, the correction information synthesizing unit 411 uses the text data, graphics data, image data, and analysis results regarding these layout information for the basic document data and the corrected document data in step S64 and step S66, and the basic document data and The correction document data is combined, the layout information is updated as necessary, and the drawing data (correction information combined document data) 415 is generated (S67). The correction information combining unit 411 temporarily stores the generated drawing data (correction information combined document data) 415 in the storage unit 404.

  In addition, although the process of said step S63, S64 and step S65, S66 is processed in parallel in a present Example, you may carry out in order of step S65, step S66, step S67, and step S68. When the generation of the drawing data (correction information composite document data 415 is completed in step 67), the layout analysis unit 416 analyzes the generated correction information composite document data 415 (S68). The print drawing unit 408 generates drawing data based on the result of the analysis processing by the layout analysis unit 416 and the printing performance information 414 stored in the printing apparatus performance information storage unit 410, and stores the drawing data in a drawing memory (not shown). Store (S69).

  When the drawing data (correction information composite document data) 415 includes image data as an encoded character string, the image decoding unit 417 performs decoding processing on the image data and outputs it to the print drawing unit 408. To do. After the drawing data is temporarily recorded in the drawing memory in step S69, the contents drawn in the drawing memory are displayed on the printing device display unit 409 (S70). In other words, when the drawing data is stored in the drawing memory, the printing / drawing unit 408 controls the printing apparatus display unit 409 to perform display based on the stored drawing data.

  In the state where the display based on the drawing data is being performed on the printing apparatus display unit 409 in this way, the printing apparatus 4 waits for a print processing start instruction from the user to the print input unit 403 (S71). Note that in the printing apparatus 4 according to the present embodiment, the printing apparatus display unit 409 performs drawing for the printing state of the document data to be printed by the processing shown in steps S68 to S70 so that the printing state can be confirmed in advance. The data (correction information composite document data) 415 is displayed. However, if it is not necessary to confirm the print state of the document data in advance, or if the printing apparatus 4 does not include the print drawing unit 408 and the printing apparatus display unit 409, the processes from step S68 to step S70 are performed. Can be omitted.

  Here, when the print input unit 403 receives a print instruction for the drawing data (correction information composite document data) 415 being displayed in step S 70, the print language conversion unit 412 is notified of the instruction. In response to the instruction from the user, the print language conversion unit 412 reads the drawing data (correction information composite document data) 415 and converts it into a print language that is a printable expression format (S72). Most of the print languages are information indicating drawing commands for the print output unit 413. Note that when the drawing data (correction information composite document data) 415 is described in the SVG format as in the present embodiment, the SVG format can also be regarded as one of the drawing commands. Therefore, the print language conversion unit 412 can easily convert the drawing data (correction information composite document data) 415 described in the SVG format into the print language. In step S 72, when the print language conversion unit 412 converts the drawing data (correction information composite document data) 415 into a print language, the converted drawing data (correction information composite document data) 415 is output to the print output unit 413. . Then, the print output unit 413 performs a printing process on a predetermined sheet based on the drawing data (correction information composite document data) 415 output from the print language conversion unit 412 (S73).

  As described above, the printing apparatus 4 according to the present embodiment performs document data printing processing based on the drawing data (correction information composite document data) 415 received from the display apparatus 2b.

  In the above-described print instruction process in the display device 2b, when a print instruction is received from the input unit 204, correction document data is acquired in step S51. However, if only the basic document data is acquired and the corrected document data cannot be acquired due to, for example, a malfunction in the conversion server 1 or the gateway 3b, the display device 2b omits step S52, and the basic document data. Are transmitted to the printing apparatus 4 only.

  When only the basic document data is transmitted from the display device 2b to the printing device 4b as described above, the printing device 4 receives only the basic document data from the display device 2b in the step S62 shown in the flowchart of FIG. I understand that. Therefore, the printing apparatus 4b decompresses the received basic document data (S63), analyzes it (S64), and uses the obtained result to convert the corrected document data corresponding to the basic document data to the conversion server 1. To request.

  As shown in FIG. 11, when the display device 2b according to the present embodiment instructs the printing device 4 to perform print processing based on the received document data, the converted document data 214 received from the conversion server 1 is more accurately displayed. The configuration is such that the packaged basic document data and the corrected document data are transmitted to the printing apparatus 4 by the transmission / reception unit B203.

  However, the display device 2b generates corrected information combined document data as drawing data 415 obtained by combining the basic document data received by the drawing unit 209 from the conversion server 1 and the corrected document data, and the corrected information combined document data. Is stored in the storage unit 205. When the printing apparatus 4 is instructed to execute the printing process, the drawing data (correction information composite document data) 415 stored in the storage unit 205 is output to the printing apparatus 4 by the transmission / reception unit B203. There may be.

  When the display device 2b is configured in this way, the printing device 4 side that executes the printing process can omit the synthesis process of the basic document data and the corrected document data, and thus includes a correction information synthesis unit 411. There is no need.

  In the following, FIG. 24 shows a print processing instruction in the display device 2b for outputting the data obtained by combining the basic document data and the corrected document data to the printing device 4 as the drawing data (correction information combined document data) 415 as described above. The description will be given with reference. FIG. 24 is a flowchart illustrating an example of a print processing instruction of the display device 2b when the correction information composite document data is generated and output to the printing device 4. In this way, in the case of the configuration for generating the correction information composite document data as the print processing data, the display device 2b has the configuration shown in FIG.

  In the display device 2b, when the input unit 204 receives a print instruction from the user, the document data composition unit 212 combines the corrected document data with the basic document data after the contents of the drawing data 415 instructed to be printed. It is determined whether the data is the basic data or only the basic document data (S91). In this determination, when it is determined that the drawing data 415 is the data after combining the corrected document data, the drawing data 415 is read from the storage unit 205, and a transmission memory (not shown) provided in the transmission / reception unit B203. (S97). On the other hand, when the document data configuration unit 212 determines that the drawing data 415 stored in the storage unit 205 is only basic document data (“NO” in S91), the corrected document data corresponding to the basic document data Is acquired (S92). That is, the document data configuration unit 212 instructs the transmission / reception unit A202 to request the conversion server 1 to transmit the corrected document data. Then, the corrected document data transmitted from the conversion server 1 in response to this request is temporarily stored in the storage unit 205.

  The determination process in step S91 can be executed as follows. That is, when the print instruction received from the user is for the document data being displayed on the display unit 211 of the display device 2b, when the document data is displayed, the document data is the basic document data and the corrected document data. For example, bit information indicating whether or not the information is based on the correction information synthesized document data synthesized based on the above is recorded. The document data configuration unit 212 can make the determination in step S91 by referring to the bit information.

  Alternatively, when the document data to be printed is described in the SVG format, it is determined whether or not the document data is correction information composite document data in the document data by using the <desc> tag, for example. Show metadata embedded. Then, the document data configuration unit 212 can make a determination with reference to information embedded in the metadata.

  Further, when a print request is instructed from a user by specifying a file name indicating document data, information indicating whether the document data is correction information composite document data in the instructed file name or extension Is included. Then, the document data configuration unit 212 can determine whether or not the document data to be printed is correction information composite document data with reference to the file name or extension.

  Next, the document data configuration unit 212 reads out the attribute information 115 together with the corrected document data, and can refer to the attribute information 115 to perform the synthesis process of the basic document data and the corrected document data in the display device 2b. Whether or not (S93). When combining processing of the basic document data and the corrected document data is possible (in the case of “YES” in S93), the compressed document data decompression unit 206 responds to an instruction from the document data configuration unit 212 and the corrected document data The decompression process is performed (S94), and the decompressed corrected document data is transmitted to the corrected document data analysis unit 208.

  The corrected document data analysis unit 208 analyzes the correction information regarding the text, graphics, and image portions included in the received corrected document data (S95), and passes them to the drawing data generation unit 215. When receiving the analyzed corrected document data from the corrected document data analysis unit 208, the drawing data generation unit 215 performs composition processing with the already analyzed basic document data and updates the layout information as necessary. (S96). Then, the drawing data generation unit 215 stores the drawing data (correction information combined document data) 415 obtained by synthesizing the basic document data and the corrected document data in the storage unit 205 and also causes the document data configuration unit 212 to display the drawing data. Instructs the printing apparatus 4 to output the business data 415.

  In response to an instruction from the drawing data generation unit 215, the document data configuration unit 212 reads the drawing data 415 from the storage unit 205 and outputs the drawing data 415 to the transmission / reception unit B203 (S97). Then, control is performed so that the drawing data 415 is transmitted to the transmission / reception unit B to the printing apparatus 4 (S98).

  If the determination in step S93 is “NO”, that is, if the display device 2b cannot synthesize the basic document data and the corrected document data, the drawing data generation unit 215 displays the basic document data analysis unit. The basic document data analyzed by 207 and the corrected document data analyzed by the corrected document data analysis unit are packaged and stored in the storage unit 205. Then, it instructs the document data configuration unit 212 to output the packaged basic document data and the corrected document data to the printing apparatus 4.

  As described above, the basic document data and the corrected document data can be combined in advance on the display device 2b side and output to the printing device 4. Then, the processing in the printing apparatus 4 in the case where the corrected document data and the basic document data are combined and transmitted to the printing apparatus 4 as described above, or packaged and transmitted to the printing apparatus 4 will be described with reference to FIGS. This will be described with reference to FIG.

  FIG. 25 shows a process of printing by the printing apparatus 4 according to the present embodiment based on drawing data 415 that is synthesized or packaged with basic document data and corrected document data as document data to be printed. It is a flowchart which shows an example.

  First, as shown in step S61 of FIG. 21, the print transmission / reception unit 402 synthesizes document data to be printed, that is, packaged basic document data and corrected document data, or these data from the display device 2b. The rendered drawing data (correction information composite document data) 415 is received (S61). In step SB, as shown in FIG. 25, the compressed document file decompression unit 405 determines whether the received document data type is packaged basic document data and corrected document data. It is determined whether it is the combined drawing data (correction information combined document data) 415 (S101).

  If the document data received in the determination in step S101 is the drawing data (correction information composite document data) 415, the process proceeds to step SC in FIG. 21, and the processes in and after step S68 are performed. That is, in this case, the processing from step S62 to step S67 can be omitted.

  On the other hand, if it is determined in step S101 that the received document data is packaged basic document data and corrected document data, the process proceeds to step S62 shown in FIG. And the process after step S62 is performed as mentioned above.

As described above, the printing apparatus 4 according to the present embodiment can perform print processing by determining the type of received document data to be printed. For this reason, the printing apparatus 4 according to the present embodiment determines whether the received document data is correction information composite document data obtained by combining the basic document data and the correction document data, or packaged basic document data and correction document. It is possible to appropriately perform the printing process depending on whether the data.

  In the data conversion system 100 according to the present embodiment described above, the conversion processing of the document data is executed in the conversion server 1, but the present invention is not limited to this. For example, the display device 2a, the gateway 3a, or the gateway 3b on the document data transmission side has the same function as that of the conversion server 1, and each function realized by the conversion server 1 is displayed on the display device 2a, The gateway 3a or the gateway 3b may have a configuration.

  In this embodiment, the document data is received by the conversion server from the display device 2a via the gateway 3a and is converted. However, the document data to be transmitted is not limited to a WEB server. The conversion process may be performed in the server via the server. Moreover, the gateway 3a, the gateway 3b, and the conversion server 1 may be the same server, and the structure performed in this server may be sufficient.

  Also, the conversion server 1 according to the present embodiment has a configuration in which the attribute information 115 of the display device 2 that is the display destination of the document data is stored in advance in the attribute information storage unit 112. However, the present invention is not limited to this, and the attribute information 115 may be acquired from the display device 2b and stored at a predetermined timing in the conversion process described below. That is, when the conversion server 1 receives the document data 114 to be transmitted to the display device 2b from the display device 2a via the gateway 3a, the conversion server 1 converts the received document data. And the conversion server 1 may be the structure which acquires the attribute information 115 of the display apparatus 2b from the display apparatus 2b via the gateway 3b or the gateway 3b as needed at the time of this conversion process.

  In the conversion server 1 according to the present embodiment, when the document data (compressed document data) is received from the display device 2a, the transmission / reception unit 102 requests the attribute information 115 from the display device 2b. However, the present invention is not limited to this.

  For example, the conversion server 1 further includes input means for receiving an input from a user who operates the conversion server 1. When the input unit receives an instruction to convert the document data 114 to be transmitted to the display device 2b, the transmission / reception unit 102 acquires the attribute information 115 from the display device 2b according to the instruction. Also good.

  The conversion server 1 is configured to acquire the attribute information 115 from the display device 2b that is the transmission destination of the document data 114, but is not limited thereto. For example, when the transmission destination of the document data 114 is always a predetermined display device, the attribute information of this display device may be recorded in the attribute information storage unit 112 in advance.

  Further, the attribute information 115 may be information set in advance in the conversion server 1 according to information such as an appropriate communication amount of data transmitted and received in the data conversion system 100 according to the present embodiment. Good.

  In the printing apparatus 4 according to the present embodiment, the processing result of the correction information combining unit 411 and the printing apparatus performance information storage unit are provided so that a user who instructs printing can check document data to be printed in advance. In accordance with the print performance information 414 stored in 410, the print drawing unit 408 can draw and display on the printer display unit 409.

  However, for example, when it is not necessary to check the print state before the display data is printed, it is not necessary to display the document data to be printed. For this reason, in such a case, the printing apparatus 4 may not include the print drawing unit 408 and the printing apparatus display unit 409.

  Further, the printing apparatus 4 according to the present embodiment is configured to execute drawing or printing processing based on the correction information combined document data generated by the correction information combining unit 411. However, the printing apparatus 4 may be configured as follows.

  That is, the printing apparatus 4 does not include the correction information combining unit 411, and the print drawing unit 408 refers to the print performance information and receives the basic document data received from the basic document data analysis unit 406 and the correction document data analysis unit. The converted document data 215 may be displayed based on the corrected document data received from 407. In addition, the print language conversion unit 412 can print the converted document data 215 based on the basic document data received from the basic document data analysis unit 406, the corrected document data received from the corrected document data analysis unit 407, and the print performance information. It may be configured to convert to the format.

  The display device 2b according to the present embodiment is configured to temporarily store the basic document data received through the gateway B3b in the storage unit 205. However, the display device 2b is not temporarily stored in the storage unit 205, but is compressed from the transmission / reception unit A202. It may be configured to be transmitted to the data decompression unit 206. In such a configuration, the trigger for starting decompression of the compressed basic document data by the compressed document data decompression unit 206 is not the display instruction from the user but the reception of the basic document data from the conversion server 1. It becomes.

  Further, in the conversion server 1 described above, for example, as shown in FIGS. 29A and 29B, it is determined whether or not each element included in the document data 114 to be transmitted is necessary based on the attribute information 115. Thus, the configuration of the converted document data to be transmitted to the display device 2b is determined. Thus, since there is no need to transmit unnecessary data in the display device 2b, the amount of data transmitted from the display device 2a to the display device 2b can be reduced.

  By the way, the method of reducing the amount of data to be transmitted by the conversion server 1 is not limited to this, and for example, the information of each element constituting the converted document data itself can be reduced as follows. . That is, it is possible to further reduce the data amount of the converted document data to be transmitted to the display device 2b by the layout information that is localization information and the drawing point deletion process in the graphics portion.

  For example, as a description method of layout information, for example, a description shown in FIG. 30A and a description including even information below a decimal point as shown in FIG. 30B can be performed. The layout information defined by the description shown in FIG. 30 (a) and the layout information defined by FIG. 30 (b) are different in arrangement between the two by a difference after the decimal point. FIG. 30A and FIG. 30B are diagrams illustrating an example of a layout information description method.

  However, in the display device 2 having a screen size of 240 dots in the width direction and 320 dots in the vertical direction, the arrangement is defined based on the layout information shown in FIGS. 30 (a) and 30 (b). In the case of drawing, etc., the difference in arrangement due to both the layout information shown in FIGS. 30A and 30B falls within 1 dot. For this reason, in the display device 2 having the above-described screen size, the drawing display position defined by the layout information of both of them can be regarded as the same position.

  Therefore, even if the layout information included in the document data 114 received from the display device 2a is described to the decimal point as shown in FIG. 30B, the display device 2b that is the transmission destination of the converted document data. For example, when the screen size is 240 dots in the width direction and 320 dots in the vertical direction, the amount of data describing the layout information can be reduced by rounding off the decimal part.

  Whether or not the data amount in the layout information is reduced can be determined as follows. That is, the layout information conversion unit 108 can determine whether to round off information after the decimal point by referring to the attribute information 115 and assuming the display capability of the display device 2b.

  In addition, when the graphics portion included in the document data 114 is expressed by a set of a large number of drawing points, the converted document data data to be transmitted to the display device 2b by thinning out some of the drawing points. The amount can be reduced.

  Specifically, for example, a part of the graphics part is described as shown in FIG. 31, and by this description, a line connecting the coordinates (1, 1) and the coordinates (2.02, 2.02) It is assumed that a line connecting coordinates (2.02, 2.02) and coordinates (3, 3) can be drawn. Then, according to the description shown in FIG. 31, the graphics portion is displayed on a display device having a screen size of 240 dots wide and 320 dots high.

  In this case, a line connecting the coordinates (1, 1) and the coordinates (2.02, 2.02) and a line connecting the coordinates (2.02, 2.02) and the coordinates (3, 3) The slope of the straight line is different. However, when the graphics portion drawn by these coordinates is displayed on the display device having the above-mentioned screen size, the display result is the case where it is expressed by a straight line connecting the coordinates (1, 1) and the coordinates (3, 3). There is no difference.

  When there is no difference in the display results as described above, the description shown in FIG. 31 can be changed to the description shown in FIG. 32, and unnecessary drawing points can be thinned out. The determination as to whether or not to thin out the drawing points can be realized as follows. That is, the graphics analysis unit 106 can determine the drawing points that can be thinned out by referring to the attribute information 115 and assuming the display capability of the display device 2b.

Finally, each block provided in the conversion server 1, the display device 2b, and the printing device 4 in the data conversion system 100 according to the present embodiment, particularly the conversion control unit 101 provided in the conversion server 1,
