  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, a preferred embodiment of the invention will be described in detail with reference to the drawings.

  FIG. 1 is a diagram showing an overall configuration of an image processing system according to an embodiment of the present invention. As shown in FIG. 1, the image processing system 10 includes a client device 20 configured by, for example, a personal computer, and a multifunction machine 30 having a print function and a scanner function. The client device 20 and the multifunction device 30 are connected to the communication network 12 and can exchange data with each other.

  The client device 20 includes a control unit 21, a storage unit 22, a network interface (network I / F) 23, and a display unit 24. The control unit 21 operates according to a program stored in the storage unit 22 and executes, for example, processing for causing the multifunction device 30 to print document data. The storage unit 22 is configured by a computer-readable recording medium and stores a program executed by the control unit 21. The storage unit 22 also operates as a work memory that stores various data required in the process of the control unit 21. The network I / F 23 is an interface to the communication network 12. The network I / F 23 outputs data received from the communication network 12 to the control unit 21. The network I / F 23 outputs various data to the communication network 12 in accordance with instructions input from the control unit 21. The display unit 24 is, for example, a display, and displays information according to instructions input from the control unit 21.

  When document data is printed from the client device 20 to the multifunction device 30, the client device 20 converts the document data into document data (PDL data) described in PDL (Page Description Language) by a built-in printer driver. Then, the PDL data is transmitted to the multi function device 30 via the communication network 12. In the multi function device 30, the received PDL data is converted into a raster image and printed out.

  The multifunction device 30 includes a network interface (network I / F) 31 for the communication network 12, a control unit 32 that controls the entire multifunction device 30, a control panel 33 that displays information to the user, key inputs, and the like, and reads a document. An image reading unit 34 for acquiring image data, an image processing unit 35 for performing predetermined image processing on the read image data and image data generation based on the control of the control unit 32, and image data output from the image processing unit 35 as printing paper The image forming unit 36 is configured to print out on an image recording medium such as the above. The network I / F 31 receives PDL data from the client device 20 through the communication network 12 and communicates with other network connection devices.

  As described above, the multifunction machine 30 has a printer mode and a scanner mode. In the printer mode, the image processing unit 35 receives the PDL data from the control unit 32 and generates document image data corresponding thereto. The document image data is output to the image forming unit 36. In the scanner mode, the image reading unit 34 reads a document image formed on a recording medium such as paper and generates image data. This image data is stored in a page buffer (memory) provided in the image processing unit 35. The read image stored in the page buffer is transferred to the control unit 32 and transmitted to the client device 20 in accordance with an instruction from the control unit 32.

  In the client device 20 according to the present embodiment, a document application for creating and printing a document is executed. This document creation application has a function (additional writing function) for adding additional information at an arbitrary position to an existing document. With this additional recording function, for example, a person other than the creator of the document can additionally add a comment, a specific mark, or the like at a predetermined position of the document.

  FIG. 2 shows an example of a document displayed on the screen of the document application. In the figure, an additional mark 41 is added to the original document (document body) by the additional function of the document application.

  The document application manages data related to the additional mark 41 (additional data) in association with the data of the document body. In other words, data including document main body data and additional data related to the additional recording mark 41 is managed as document data. Note that the postscript data related to the postscript mark 41 includes, for example, image data of the postscript mark 41, data indicating the position and size when the postscript mark 41 is displayed on the document, attribute data of the postscript mark 41, and the like. The attribute data of the postscript mark 41 includes data indicating the person who added the postscript mark 41 and the date of addition.

  In the image processing system 10, when document data of a document application is printed, additional data included in the document data can be embedded in an image (print image) formed on a print medium such as paper. ing. When a print image is read by a scanner or the like, additional data can be extracted from the read image. In particular, the image processing system 10 can facilitate the extraction of the postscript data from the read image, and can suitably restore the document data from the read image. Yes.

  FIG. 3 shows an example of an image formed on a print medium such as paper when document data of a document application is printed out by the image processing system 10. This figure shows an example in which the document shown in FIG. 2 is printed out. As shown in the figure, an additional data code image 42 and a decoding condition guide image 43 are formed in the print image together with an image representing the document body.

  The additional recording data code image 42 is an image corresponding to the additional recording mark 41, and is an image generated based on the image data related to the additional recording mark 41. As shown in the figure, the postscript data code image 42 is formed at a position on the print image corresponding to the display position of the postscript mark 41 in the document.

  Further, the attribute data related to the additional recording mark 41 is embedded in the additional recording data code image 42 so as to be readable by a computer. More specifically, the additional record data code image 42 is an image obtained by translucently combining the code image of the attribute data related to the additional record mark 41 with the image data related to the additional record mark 41. Here, the code image of the attribute data related to the write-once mark 41 is, for example, an image in which unit pattern images respectively representing “0” and “1” are arranged to indicate the encoded data of the attribute data related to the write-once mark 41 It is. Unit pattern images representing “0” and “1” are images having different brightness patterns, for example. In the figure, the additional recording data code image 42 is shown so as to be distinguishable from the additional recording mark 41 in FIG. 2, but in actuality, it is formed so as to be difficult to distinguish with the naked eye.

  FIG. 4 is an enlarged view of the area where the additional data code image 42 and the decoding condition guide image 43 are displayed in the print image. As shown in the figure, the decoding condition guide image 43 is formed so that the upper right pixel thereof is adjacent to the upper left pixel of the additional data code image 42. The decoding condition guide image 43 is an image in which the up / down (left / right) direction can be discriminated, and is formed so that the upright direction coincides with the upright direction of the postscript data code image 42. In FIGS. 3 and 4, the decoding condition guide image 43 is shown so that it can be identified, but in practice, it is formed so that it is difficult to identify with the naked eye.

  When such a print image is read by a scanner or the like and additional record data is extracted from the read image, the decoding condition guide image 43 is detected and its position and orientation are acquired, whereby the additional record data code image 42 in the read image is obtained. It becomes possible to identify the position and orientation of the camera relatively easily. As described above, the decoding condition guide image 43 plays a role of indicating the position and orientation of the additional data code image 42 depending on the position and orientation thereof.

  In the print image, the decoding condition guide image 43 may be formed in a part of a region where the additional data code image 42 is formed. For example, as shown in FIG. 5, the decoding condition guide image 43 may be semitransparently combined with the postscript data code image 42 so that the position of the upper right pixel and the upright direction of each other coincide. That is, the decoding condition guide image 42 is translucently combined with the image data related to the postscript mark 41 so that the upper right pixel and the upright direction of each other coincide with each other. A semi-transparent composite image may be formed on a printed image. Thus, even if the additional record data code image 42 and the decoding condition guide image 43 are formed on the print image, the position and orientation of the additional record data code image 42 in the read image can be easily specified.

  Further, for example, a code image in which position data for specifying a region in which the additional record data code image 42 is formed may be formed on the print image as the decoding condition guide image 43. That is, position data indicating the position of the additional record data code image 42 on the print image is acquired, the position data is encoded, a code image is generated based on the code data, and the code image is referred to as the decoding condition guide image 43. You may make it do. In this case, for example, as shown in FIG. 6, the decoding condition guide image 43 may be formed at a predetermined position (fixed position) of the print image. Here, when an image that can be detected from a print image, such as a two-dimensional barcode image, by a known method is used as the decoding condition guide image 43, the decoding condition guide image 43 is placed at an arbitrary position. You may make it form. Even in the above-described manner, the position of the additional data code image 42 in the read image can be specified by detecting the decoding condition guide image 43 and acquiring the position data embedded therein. As described above, the decoding condition guide image 43 may play a role of indicating the position of the additional data code image 42 in the read image depending on the information content held. Even in this case, it is preferable that the decoding condition guide image 43 is an image in which the vertical (left / right) direction can be determined.

  Next, functional blocks realized by the image processing system 10 will be described. FIG. 7 is a diagram mainly showing those related to the present invention among the functional blocks realized in the image processing system 10. As shown in the figure, the image processing system 10 includes an additional write data acquisition unit 51, an additional write data code image generation unit 52, an additional write data code image formation unit 53, a decoding condition guide image formation unit 54, an image reading unit 55, and a decoding condition. It includes a guide image detection unit 56, a postscript data extraction unit 57, and a process execution unit 58. These functions are realized by a computer executing a program supplied by a computer-readable information storage medium or a communication network.

  The additional data acquisition unit 51 (related data acquisition unit) acquires additional data (related data) related to the document body data (document data) when printing of the document data of the document application is executed. In the case of the present embodiment, the postscript data acquisition unit 51 reads the postscript data stored in association with the document body data.

  The additional write data code image generation unit 52 (related data code image generation unit) encodes at least a part of the additional write data acquired by the additional write data acquisition unit 51. Then, based on the code data, a computer readable additional data code image is generated. In the present embodiment, a recordable data code image 42 as shown in FIG. 3 or the like is generated based on code data obtained by encoding the attribute data included in the recordable data and image data included in the recordable data.

  The additional data code image forming unit 53 (related data code image forming unit) forms the additional data code image generated by the additional data code image generation unit 52 in a part of the print image. In the present embodiment, the additional data code image forming unit 53 determines the position of the additional data code image in the print image based on the position data included in the additional data. More specifically, an additional write data code image is formed at a position on the print image corresponding to the position of the additional write mark 41 in the document.

  The decoding condition guide image forming unit 54 forms a decoding condition guide image for guiding the decoding conditions of the additional data code image on the print image. For example, a decoding condition guide image that guides decoding conditions such as the position of the additional recording data code image (area where the additional recording data code image is formed) and the direction is formed.

  For example, the decoding condition guide image forming unit 54 uses a predetermined image capable of discriminating the vertical direction and the left and right direction as the decoding condition guide image (see FIGS. 3 to 5).

  Further, for example, the decoding condition guide image forming unit 54 determines the position of the decoding condition guide image based on the position of the additional data code image. For example, as shown in FIG. 4, the decoding condition guide image may be formed so as to be adjacent to the additionally recorded data code image. Further, for example, as shown in FIG. 5, the decoding condition guide image may be formed in a part of the area where the additional data code image is formed.

  Further, for example, the decoding condition guide image forming unit 54 determines the direction of the decoding condition guide image based on the direction of the additional data code image formed on the print image, and forms the decoding condition guide image in that direction. For example, as shown in FIGS. 4 and 5, the decoding condition guide image may be formed such that its upright direction (reference direction) matches the upright direction (reference direction) of the additionally recorded data code image. .

  For example, as shown in FIG. 6, the decoding condition guide image forming unit 54 forms a code image indicating position information for specifying an area where the additional data code image is formed as a decoding condition guide image. Also good.

  Here, the additional recording data acquisition unit 51, the additional recording data code image generation unit 52, the additional recording data code image formation unit 53, and the decoding condition guide image formation unit 54 are the client device 20 (image processing device) and the multifunction device 30 (image processing device). ) May be realized.

  For example, when a document application executes printing of document data, print document data on which a postscript data code image or a decoding condition guide image is formed is generated based on the document data, and the print document data is printed on a printer. You may make it supply to a driver. Alternatively, when the printer driver converts the document data into PDL data, a write-once data code image or a decoding condition guide image may be formed. As described above, the additional recording data acquisition unit 51, the additional recording data code image generation unit 52, the additional recording data code image formation unit 53, and the decoding condition guide image formation unit 54 may be realized by the client device 20.

  Further, for example, when the multifunction device 30 performs conversion from PDL data to a raster image, a write-once data code image or a decoding condition guide image may be formed. As described above, the additional recording data acquisition unit 51, the additional recording data code image generation unit 52, the additional recording data code image formation unit 53, and the decoding condition guide image formation unit 54 may be realized by the multifunction machine 30.

  As described above, when document data of a document application is printed by the image processing system 10, additional data associated with the document is printed on the printed material so as to be readable by a computer. For this reason, when this printed matter is read by a scanner or the like, additional data can be acquired from the read image. In particular, the printed matter printed by the image processing system 10 is printed with the additional data code image in which the additional data is embedded and the decoding condition guide image for guiding the decoding conditions of the additional data code image. It is possible to obtain additional data relatively easily.

  Next, a configuration for reading a printed matter in which additional recording data is embedded and acquiring additional recording data from the read image will be described.

  The image reading unit 55 reads a printed material on which a print image as shown in FIG. 3 is formed, for example, and generates the image data.

  The decoding condition guide image detection unit 56 detects the decoding condition guide image from the read image data generated by the image reading unit 55. That is, the decoding condition guide image detection unit 56 scans the entire read image and searches for the decoding condition guide image. When the decoding condition guide image is detected, the decoding condition guide image detecting unit 56 determines the nature of the decoding condition guide image (for example, the position and orientation of the decoding condition guide image in the print image, or the pattern image formed on the decoding condition guide image). ) To get.

  For example, when the decoding condition guide image is formed as shown in FIGS. 4 and 5, that is, the decoding condition guide image is formed so as to guide the position and orientation of the additional data code image according to the position and orientation of the decoding condition guide image. In this case, the decoding condition guide image detection unit 56 determines the position (reference position) of the reference pixel of the decoding condition guide image in the read image (for example, the upper right pixel or the upper left pixel when the decoding condition guide image is erected). To get. In addition, the direction of the decoding condition guide image in the read image, that is, the angle (rotation direction) of the erecting direction of the decoding condition guide image with respect to the erecting direction of the read image is acquired.

  For example, when the decoding condition guide image is formed as shown in FIG. 6, that is, when the decoding condition guide image is formed so as to guide the position and orientation of the additional data code image based on the information held in the decoding condition guide image. The decoding condition guidance image detection unit 56 acquires information held in the decoding condition guidance image. For example, by detecting the pattern image formed in the decoding condition guide image, the code data embedded in the decoding condition guide image is acquired, and by decoding such code data, the position and orientation of the additional data code image are determined. Get information to identify.

  The additional recording data extraction unit 57 extracts additional recording data from the read image data based on the properties of the decoding condition guide image detected by the decoding condition guide image detection unit 56.

  First, the additional recording data extraction unit 57 specifies an area where the additional recording data code image is displayed. For example, when the decoding condition guide image is formed as shown in FIGS. 4 and 5, the additional data code image is based on the position of the reference pixel of the decoding condition guide image and the direction of the decoding condition guide image in the read image. The area where is displayed can be specified. For example, the additional record data extraction unit 57 performs scanning in a predetermined direction based on the direction of the decoding condition guide image from the position of the reference pixel of the decoding condition guide image. Then, the range in which the unit pattern image corresponding to “0” or “1” used when the additional recording data code image is generated is specified as the region where the additional recording data code image is displayed.

  On the other hand, for example, when the decoding condition guide image is formed as shown in FIG. 6, when the decoding condition guide image is formed at a fixed position of the print image, the additional data extraction unit 57 sets the predetermined area of the read image. The additional data code image is detected by scanning. In addition, when a two-dimensional barcode image is used as the decoding condition guide image and is formed at an arbitrary position of the print image, the additional data extraction unit 57 performs a two-dimensional bar code on the entire print image by a known search method. Search for code images. When the decoding condition guide image is detected, the code data held therein is extracted and decoded to acquire information for specifying the display area of the additional data code image.

  After specifying the display area of the additional data code image, the additional data extraction unit 57 detects a pattern image (an array of unit pattern images representing “0” or “1”) formed in the area, and the encoded data To get. Then, by decoding this, the attribute data of the additional write data is acquired. Further, the additional write data extraction unit 57 acquires the image data of the additional write data by cutting out the image of the area from the read image.

  As described above, the image data and the attribute data of the additional write data are extracted from the read image. Further, since the display area of the additional write data code image is specified, the position data of the additional write data is also acquired.

  The process execution unit 58 executes a predetermined process based on the additional write data extracted by the additional write data extraction unit 57. For example, the process execution unit 58 converts the read image into a document application data format. That is, the read image is converted into document body data of the document application. Then, the process execution unit 58 generates additional write data based on the image data, the position data, and the attribute data extracted by the additional write data extraction unit 57, and stores the additional write data in association with the document body data. As described above, the process execution unit 58 may generate document data of the document application based on the additional write data extracted by the additional write data extraction unit 57.

  The image reading unit 55 mainly includes the image reading unit 34 of the multifunction machine 30. On the other hand, the decoding condition guide image detection unit 56, the additional write data extraction unit 57, and the process execution unit 58 may be realized by any of the client device 20 (image processing device) and the multifunction device 30 (image processing device). Good. That is, the processing executed by these functional blocks may be executed by the client device 20 that has received the read image data from the multi-function device 30 or may be executed by the multi-function device 30 itself. .

  Here, it has been described that the postscript data code image is cut out from the read image of the print image, and this is used as image data of the postscript data to generate document data. However, the postscript data code image is obtained by translucently combining a predetermined code image with the original image data (see FIG. 3). Therefore, when printing document data, the image data of the additional data is stored in a server connected to the communication network 12, and information necessary for reading the image data is held in the additional data code image. It may be. When document data is generated from the read image, the image data stored in the server may be read. Similarly, when printing document data, the document body data may be stored in the server. In this way, even if the additional record data code image overlaps the document body in the print image, the original document of the overlapping portion can be referred to in the document data generated from the read image.

  As described above, in the image processing system 10, when document data is printed, additional data associated with the document is embedded in the printed matter. Then, the additional write data can be extracted from the read image obtained by reading the printed matter. In particular, in the image processing system 10, additional record data is embedded at an unspecified position of a printed matter, but extraction of the additional record data can be realized by a relatively simple process. In the image processing system 10, the original document data can be suitably reproduced from the read image.

  The present invention is not limited to the embodiment described above.

  For example, the case where one additional record data is associated with the document body data has been described above as an example, but a plurality of additional record data may be associated with the document body data. In this case, the additional recording data code image may be formed for each additional recording data. As for the decoding condition guide image, a decoding condition guide image is formed for each additional write data in the case as shown in FIGS. 4 and 5, and in the case shown in FIG. A decoding condition guide image may be formed.

  Further, for example, the case where printing is performed by embedding additional writing data stored in association with the document body data has been described above. However, additional writing data (related data) is input by the user when printing the document data. It may be.
