Description

  The present invention relates to a document creation device that creates a printed material on which an original image and an auxiliary image that is a code image are displayed, and a searchable file creation device that creates a searchable file by reading the printed material.

  An MFP (Multi Function Printer) can read a document with a scanner and convert it to an electronic file. Using this function, a searchable PDF (Portable Document Format) file, which is a type of searchable file, can be converted. There is something that can be created. Here, the searchable file is a file to which text search is possible by adding invisible text data (character code data). In such an apparatus, the searchable PDF file uses OCR (Optical Character Recognition) technology to extract text information described in a document, and the scanned image and text data are stored in the PDF file. Created by embedding in. In this searchable PDF file, not only can the scanned image be viewed, but also the text data is embedded, so it is possible to perform electronic searches using text data and to easily copy and paste text data. Or

  In Patent Document 1, when creating a searchable file (generic name including a searchable PDF file, a searchable XPS (XML Paper Specification) file, etc.), the user can arbitrarily set the character recognition level and the character extraction accuracy ( (Recognition accuracy) can be confirmed, and an image forming apparatus and an image forming program that can generate a high-quality searchable file smoothly by repeating these processes are described.

  The character recognition rate (recognition accuracy) by the OCR technology has a limit, and depending on the shape and type of the character, it may not be recognized correctly. In this case, if it is misrecognized as content that does not hold as a sentence, it is easy to detect misrecognition. However, there are various misrecognition results. For example, sentences themselves are connected without a sense of incongruity, but sentences having completely opposite meanings may be generated. In the case of a searchable PDF file, the content displayed in the viewer is not text data recognized by OCR but is read as an image, and is not affected by erroneous recognition at this point. However, when misrecognition by OCR has occurred, search omissions occur during electronic search using text data, and erroneous contents are copied when text data is copied. For this reason, depending on the intended use, it is necessary for humans to compare the original document with the generated document and correct the erroneous part.

  As another problem, when a searchable PDF is created by the MFP, the text portion of the document is not replaced with a character code but held as image data. For this reason, there is a problem that the file size becomes larger than that of a PDF file in which a PDF file is directly created on a computer and a text portion is stored as character code data.

  The present invention has been made in view of the above-described problems. A document creation apparatus that creates a printed material that can easily create a searchable file and that can reduce the file capacity, and a searchable that creates a searchable file from the printed material. An object is to provide a file creation device.

In order to solve the above problems, a text display surface on which a document image is displayed based on document data, and an auxiliary material display surface on which an auxiliary image in which auxiliary data including at least a part of the document data is converted into a code image are displayed. A document creation apparatus for creating a printed matter comprising: auxiliary data generation means for generating the auxiliary data from the document data; and an image of the auxiliary image from the auxiliary data generated by the auxiliary data generation means Image conversion means for generating data;

  Hereinafter, modes for carrying out the present invention will be described. The present invention has the following characteristics in order to make it possible to create a searchable file, which is an electronic file that can be electronically searched, from a printed material on which an original image is printed. That is, according to the present invention, when creating a body sheet on which an original image is recorded as a printed matter, an auxiliary material sheet, which is a recording medium for displaying an auxiliary image in which digital information lost by printing is converted into a code image, is created. A sheet and an auxiliary material sheet are handled as one set.

Hereinafter, a printed matter, a document creation device, and a searchable file creation device according to embodiments will be described.
First, a procedure from creation of a printed material according to the embodiment to creation of a searchable file from the printed material will be described. FIG. 1 is a schematic diagram showing a flow from creation of a printed matter to searchable file creation in the embodiment of the present invention.
In order to create the printed matter 10, the document creation device 100 is used. The document creation apparatus 100 includes a computer 200 and an MFP (Multi Function Printer) 300.
In addition, the searchable file creation device 400 is used to create a searchable file from the printed material 10. The searchable file creation device 400 includes a computer 500 and an MFP 600.
In this example, the printed material 10 is a sheet-like recording medium such as printing paper, and the body sheet 20 on which the original image 30 is printed and the auxiliary material sheet 40 on which the auxiliary image 50 is printed are handled as one set. It is. The auxiliary image 50 is obtained by converting a part of document data for printing the document image 30 into a code image.

In addition, one auxiliary material sheet 40 is set as one set for one body sheet 20, and a plurality of auxiliary material sheets 40 can be set as one body sheet 20. Further, one auxiliary material sheet 40 can be paired for a plurality of printed materials 10. Furthermore, the original image 30 and the auxiliary image 50 can be printed on both sides of one recording medium, and the original image 30 and the auxiliary image 50 can be printed on one side of one recording medium. . As described above, it is sufficient that the document image 30 is displayed on the portion (text display surface) where the text is displayed in the sheet-like recording medium. Similarly, it is sufficient that the auxiliary image 50 is displayed on a portion (auxiliary material display surface) for displaying auxiliary data in the sheet-like recording medium.
How to form the original image 30 and the auxiliary image 50 on the sheet-like recording medium may be appropriately selected according to the usage mode of the printed matter 10.

  In the document creation apparatus 100, document data having contents to be printed on the body sheet 20 is created by document creation software (word processor software) stored in the computer 200, and this is printed on the body sheet 20 by the MFP 300. At this time, creation of the auxiliary material sheet 40 that facilitates creation of the searchable file is instructed by the user's specification. Then, the computer 200 creates auxiliary data for printing the auxiliary material sheet 40 in addition to the original data for printing the body sheet 20 created by the user. Based on these data, the MFP 300 prints the original image 30 on the body sheet 20 and the auxiliary image 50 on the auxiliary material sheet 40.

To create a searchable file from the printed material 10, the text sheet 20 and the auxiliary material sheet 40 are optically read by the MFP 600 of the searchable file creation device 400 as a set, and image data of the original image 30 and the auxiliary image 50 To get. Then, auxiliary data is decoded from the auxiliary image 50. Thus, in MFP 600, an electronic file in which text or the like is replaced as auxiliary data from auxiliary image 50 of auxiliary material sheet 40 is created and transmitted to computer 500 together with image data of body sheet 20. In response to this, the computer 500 can use the description content of the body sheet 20 by searching for characters using an electronic file, or pasting the content of text or the like in another document by cut-and-paste processing.
Next, the printed matter according to the embodiment will be described. FIG. 2 is a schematic diagram showing a document sheet and an auxiliary material sheet that are printed matter according to the embodiment of the present invention. The printed material 10 includes a body sheet 20 and an auxiliary material sheet 40. On the body sheet 20, as a document image 30, a table 28 is printed as a document image 30 in addition to image data such as desired character strings 21, 22, 23, 26, 27 and 29, photographs 24 and 25.

  On the other hand, an auxiliary image 50 is displayed on the auxiliary material sheet 40. In this example, the auxiliary material sheet 40 displays a character string 41 as a title. The auxiliary image 50 is a code image obtained by encoding (encoding) selected digital data of the body sheet 20 in a predetermined format. The contents to be encoded include, for example, text content information of character strings, vector information of graphics, information on image data reference locations, and the like.

  Here, an example of the contents of the auxiliary material is shown. It is assumed that (1) a character string (text), (2) a graph, and (3) a photograph are included. Digital data representing the print content characteristics of such a document includes (1) ASCII code of text, size, start position, character spacing, font name, (2) vector information for creating graph contents, (3) The position where the photo is printed in the text. These digital data are converted into corresponding image data by the image converter and printed on the auxiliary material sheet 40. In addition, (3) the position where the photo is printed in the text means that the photo in the text is referred to (used) when digitized, and the contents constituting the photo itself in the auxiliary material sheet Is not included. This can be selected according to the amount of information allowed in the auxiliary material sheet. (2) For vector information for creating the graph contents, it is possible to refer to the figure in the text instead of the vector information. good.

  As described above, the printed material including the text sheet and the auxiliary material sheet as a set can be distributed at low cost because it is paper. For example, when this printed matter is a seminar text, it can be easily distributed at a lower cost than when it is distributed on a CD (Compact Disc) or other medium. In addition, if this printed matter is an advertising medium, it can be expected to be stored as electronic data by adding information that is beneficial to the user along with the text sheet in the auxiliary material sheet. is there. In addition, when a searchable file is created from this printed matter, accuracy during data conversion can be expected.

Next, the configuration of the document creation device 100 and the searchable file creation device 400 will be described. First, the document creation apparatus 100 will be described. FIG. 3 is a block diagram showing the configuration of the document creation apparatus. The document creation apparatus 100 includes a computer 200 and an MFP 300.
The computer 200 has a known configuration including a CPU, a ROM, a RAM, and the like. Further, the computer 200 includes a document creation unit 210 such as word processor software. The document creation unit 210 creates document data by a known method by a user operation. An input device 220 such as a keyboard and a mouse and a display device 230 such as a liquid crystal monitor are connected to the computer 200. The user creates a document by the document creation unit 210 using the input device 220 and the display device 230.

  In addition, the MFP 300 includes a display data generation unit 310 and an image conversion unit 320 in addition to an image forming unit 330 that forms an image by electrophotography. The display data generation unit 310 selects auxiliary data to be displayed on the auxiliary material sheet 40 from the generated document data. The image conversion unit 320 converts the data selected by the display data generation unit 310 into a code image and generates image data for generating the auxiliary image 50 of the auxiliary material sheet 40.

  The image forming unit 330 prints the original image 30 of the body sheet 20 based on the original data created by the document creating unit 210, and the auxiliary image of the auxiliary material sheet 40 based on the image data formed by the image forming unit 330. 50 is printed. Although the text sheet 20 and the auxiliary material sheet 40 form a pair, one or two or more auxiliary material sheets 40 can be formed on one text sheet 20. The number of auxiliary material sheets 40 depends on the amount of data generated by the display data generation unit 310. As a result, the text sheet 20 and the auxiliary material sheet 40 are output as the printed matter 10. Also, one auxiliary material sheet 40 can be created for a plurality of body sheets.

  In this example, the display data generation unit 310 and the image conversion unit 320 are arranged in the MFP 300, but the display data generation unit 310 and the image conversion unit 320 can be arranged in the computer 200. In this case, a printer having only a printing function can be used in place of the MFP 300.

  Next, the searchable file creation device 400 will be described. FIG. 4 is a block diagram showing the configuration of the searchable file creation apparatus. The searchable file creation apparatus 400 includes a computer 500 and an MFP 600. The computer 500 includes a searchable file storage unit 510 in addition to a known configuration such as a CPU, a ROM, and a RAM. The computer 500 is connected to an input device 520 such as a keyboard and a mouse, and a display device 530 such as a liquid crystal monitor. The searchable file storage unit 510 includes a search data storage unit 511 and an image data storage unit 512. The searchable file storage unit 510 is composed of, for example, an HDD (Hard Disc Drive).

  The MFP 600 includes a scanner 610, a data extraction unit 620, and an electronic file creation unit 630. The scanner 610 scans the text sheet 20 and the auxiliary material sheet 40 that are the printed matter 10 to acquire image data. The data extraction unit 620 extracts electronic data from the acquired image data of the auxiliary material sheet 40. The electronic file creation unit 630 processes the acquired electronic data into a searchable file. The image data of the body sheet 20 obtained by the scanner 610 is stored in the image data storage unit 512 of the computer 500, and the electronic file created by the electronic file creation unit 630 is stored in the search data storage unit 511. These data can be used as searchable files.

  In this example, the data extraction unit 620 and the electronic file creation unit 630 are arranged in the MFP 600, but the data extraction unit 620 and the electronic file creation unit 630 can be arranged in the computer 500. In this case, instead of the MFP 600, a scanner having only a scan function can be used.

  Next, the controller unit of the MFP 300 will be described. The MFP 300 will be described as being commonly used by the document creation apparatus 100 and the searchable file creation apparatus 400. FIG. 5 is a block diagram illustrating a controller unit of the MFP used in the document creation apparatus and the searchable file creation apparatus according to the embodiment. The MFP 300 includes a CPU (Central Processing Unit) 301, a bus 302, a RAM (Random Access Memory) 303, a ROM (Read Only Memory) 304, an HDD (Hard Disc Drive) 305, a network IF controller 306, a scanner I / F 307, a printer I. / F308, an operation unit 309, and a display data generation unit 310.

  A CPU 301 controls the entire MFP 300. A bus 302 connects each unit. The RAM 303 is used as a working memory when the CPU 301 performs each process. The ROM 304 stores nonvolatile data. The HDD 305 stores an OS (Operating System), programs, data, and the like. A network IF controller 306 connects the network and the MFP 300. A scanner I / F 307 is an interface to which a scanner 610 is connected. A printer I / F 308 is an interface to which the image forming unit 330 is connected. The operation unit 309 constitutes a man-machine interface for the user to operate the MFP 300.

  The above configuration is the same as the configuration of a controller unit of a general MFP conventionally used. The MFP 300 used in the present embodiment has a characteristic function to be used for the document creation apparatus 100 and the searchable file creation apparatus 400. That is, the MFP 300 includes a digital data / image data encoding unit 311, an image data / digital data decoding unit 312, and a searchable file creation unit 313.

  Display data generation unit 310 generates auxiliary data obtained by extracting digital data representing the content of document image 30 to be printed by MFP 300 from the document data. Specifically, a text code, font name, font size, drawing position, drawing position of an image handled as image data, vector information of a figure, and the like are extracted.

The digital data / image data encoding unit 311 converts the digital data extracted by the display data generation unit 310 into code image image data corresponding to the content. The digital data / image data encoding unit 311 corresponds to the image conversion unit 320 in FIG. Here, the digital data / image data encoding unit 311 handles an image as image data, and does not encode the image data itself. Therefore, the amount of information to be converted into the auxiliary image 50 can be reduced, and the number of auxiliary material sheets 40 can be reduced.
Note that when encoding to image data, an encoding parameter (conversion parameter) can be set from the user via the operation unit or the PC. That is, the digital data / image data encoding unit 311 also functions as an encoding parameter setting unit (conversion parameter setting unit) for setting an encoding parameter.

The generated code image is printed on the auxiliary material sheet 40 by the image forming unit 330 as the auxiliary image 50. As described above, since the encoding parameter can be set by the user, even when the same data created by the computer 200 is printed, changing the parameter setting changes the encoding method. Different auxiliary images 50 are printed. Therefore, only the person who knows the parameters can use the auxiliary material sheet 40 normally, and a kind of encryption can be applied.
The parts of the auxiliary image 50 that can be changed by the encoding parameter are, for example, (1) the presence / absence of the guide of the block area edge part and the size difference, (2) the difference in the vertical / horizontal number of the sub-block, The presence or absence of surrounding guides and the difference in size, (4) the difference in size of one matrix, and the like can be mentioned. Note that these appear as a format difference in the auxiliary image in appearance.

The image data / digital data decoding unit 312 performs the reverse process of the digital data / image data encoding unit 311 described above, and decodes (decodes) the auxiliary image 50 obtained by scanning the auxiliary material sheet 40 with the MFP 600. Extract auxiliary data. The image data / digital data decoding unit 312 corresponds to the data extraction unit 620 of FIG.
The searchable file creation unit 313 generates a searchable file using the auxiliary data extracted by the image data / digital data decoding unit 312 and the scanner result of the body sheet 20 by the scanner 610 connected to the scanner I / F 307. To do. The searchable file creation unit 313 corresponds to the electronic file creation unit 630 in FIG.

  The searchable file creation unit 313 replaces a part of the scanner result (image data) with electronic data when generating a searchable file. That is, the searchable file creation unit 313 uses the information included in the auxiliary data portion to convert a searchable file obtained by replacing text code, font name, font size, drawing position, graphic vector information, etc. with electronic data. Generate. As a result, the file size of the searchable file can be reduced as compared to the case where data that can be replaced with electronic data is held as image data. Moreover, since these can be handled as electronic data, the handleability and convenience of searchable files are improved. The searchable file creation unit 313 extracts the image in the text sheet with reference to “the drawing position of the image handled as image data” included in the auxiliary image 50, and holds it as image data in the searchable file.

  Note that when decoding the auxiliary image 50, a decoding parameter (extraction parameter) can be set by the user via the operation unit or the PC. In other words, the image data / digital data decoding unit 312 also functions as decoding parameter setting means (extraction parameter setting unit) for setting decoding parameters. Of course, the user cannot normally decode the auxiliary image 50 unless the decoding parameter corresponding to the encoding parameter applied to the auxiliary image 50 is set. That is, the range of users who can use the information included in the auxiliary image 50 can be limited.

  Next, the auxiliary image 50 of the auxiliary material sheet 40 will be described. FIG. 6 is a schematic diagram showing the format of the auxiliary image drawn on the auxiliary material sheet. FIG. 7 is a diagram showing data stored in the auxiliary image of the auxiliary material sheet corresponding to the body sheet shown in FIG. The auxiliary image 50 shown in FIG. 6 is a kind of two-dimensional code image.

  As shown in FIG. 6A, the auxiliary image 50 formed on the auxiliary material sheet 40 is displayed with guides 51 shown as vertical lines and horizontal lines around it. One rectangular area surrounded by the guide 51 is a block 52. The guide 51 is used as a reference position when the auxiliary image 50 is decoded into auxiliary data. In one block 52, a sub-block 53 composed of a matrix of 8 rows and 8 columns is arranged (FIGS. (B) and (c)). White and black are selected and printed for each matrix unit. As a result, each of the 64 areas of each block 52 displays 1-bit information, and the information of “8 Bytes” can be displayed in one block 52 ((c) in the figure). In the present embodiment, the auxiliary image 50 enables printing corresponding to the digital data content.

As the auxiliary image 50 of the auxiliary material sheet 40, the bit corresponding to the binary number 1 is drawn in black, the bit corresponding to the binary number 0 is drawn as white in units of 8 bits = 1 byte from the upper left block 52. In the example shown in FIG. 6, one matrix is configured with 300 dpi pixels. In this case, a matrix of about 270 blocks in width and 380 blocks in length can be arranged in A4 vertical size, and information for 8 bytes can be displayed in one block. In this example, 270 × 380 × 8/1024 = 801 kBytes of information can be expressed. This drawing method is an example, and drawing can be performed with redundancy according to a user instruction, or drawing can be performed after scrambled digital data by a known method based on given parameters. .
As the auxiliary image 50, other types of one-dimensional code images (eg, one-dimensional barcode), two-dimensional code images (eg, two-dimensional barcode), and the like can be used. The format of the auxiliary image 50 can be appropriately selected according to the amount of information included in the auxiliary image. Further, the code image embodied as the auxiliary image 50 is an image that can be mechanically decoded with 100% accuracy, and does not cause erroneous recognition like OCR.

  Next, an example of the body sheet 20 and data stored in the auxiliary image 50 corresponding to the document image 30 of the body sheet 20 will be described. FIG. 7 is a diagram showing data stored in the auxiliary image of the auxiliary material sheet corresponding to the body sheet shown in FIG. In the example shown in FIG. 7, the text sheet 20 of FIG. 2 includes the image data such as desired character strings 21, 22, 23, 26, 27, 29, photographs 24, 25, etc. 28 is printed as a document image 30.

  The auxiliary image 50 of the auxiliary material sheet 40 is created based on the selected data among the data representing the document image 30. That is, the auxiliary image 50 is drawn based on the following data. As shown in FIG. 7, these are the positions of character strings 21, 22, 23, 26, 27, font, font size, text data, the position of the character string represented by Table 28, font, font size, text data, character The position of the column 29, the font, the font size, the text data, the positions of the photographs 24 and 25, and the position of the ruled line in the table 28 are included. In this example, the displayed data is 2 Kbytes, which can be sufficiently stored in one auxiliary material sheet.
