Description

  The present invention relates to an image processing apparatus that performs at least one of image printing output and optical image reading, and more particularly, to an image reading apparatus that performs printing output or image reading on a paper in which a wireless tag is embedded. Furthermore, the present invention relates to a wireless tag embedded sheet used in such an image processing apparatus.

  In recent years, wireless tags that can read and write personal authentication information and article management information in a non-contact manner are being used in various forms. As a wireless tag, for example, an RFID (Radio Frequency Identification) tag is widely known. An RFID tag is a wireless IC chip capable of recording information, and has a function of transmitting and receiving information to and from a dedicated reader using radio waves, and is used for identifying an object to be embedded by embedding the RFID tag. There are various shapes such as a label type, a card type, a coin type, and a stick type, and the communication distance ranges from several millimeters to several meters. Furthermore, there is a battery that can be used semipermanently without a battery by a non-contact power transmission technique from the antenna side.

  It has been proposed that a wireless tag typified by such an RFID tag is used also in the field of image processing apparatuses such as a printer device, a scanner device, and a copying machine. In other words, some image processing apparatuses perform print output or image reading on a paper in which a wireless tag is embedded. Specifically, print setting information, image processing parameter information, image area information, attribute information, and the like are stored in a wireless tag embedded in paper, and information is also read from the wireless tag when reading an image. Some control image processing operations on image data obtained by image reading while following information read from the wireless tag (see, for example, Patent Documents 1 to 3).

JP 2004-88580 A JP 2004-88583 A JP 2004-88585 A

By the way, as an image processing apparatus, an apparatus having an automatic paper reversing mechanism and capable of performing print output or image reading on both surfaces (front and back surfaces) of the paper is widely used.
However, in an image processing apparatus capable of processing both sides of a sheet, when a sheet with a wireless tag embedded is used as a processing target, information stored in the wireless tag is information on either the front surface or the back surface of the sheet. Therefore, it is not always possible to properly use the stored information in the wireless tag. That is, there is a possibility that the stored information in the wireless tag cannot be effectively used unless the image processing apparatus performs processing only on one side of the sheet.
This is not only when processing is performed on both sides of a sheet, but when, for example, a bundle of sheets loaded with a plurality of sheets is stored information is read from the wireless tags of each sheet constituting the bundle of sheets at once. And the same is true. This is because it is impossible to determine which side of each sheet the information read from the wireless tag is.

  Accordingly, the present invention provides an image processing apparatus and a wireless tag embedded paper that can associate each side of the paper with information in the wireless tag when the wireless tag is embedded in the paper to be processed. For the purpose.

  The present invention is an image processing apparatus devised to achieve the above object, and communicates with an image output means for printing out an image on paper and a wireless tag embedded in the paper in a non-contact manner. A communication unit that writes information to the wireless tag, and the communication unit includes management information about an image printed by the image output unit and surface identification information about the paper on which the image is printed. Are written in the wireless tag in association with each other.

  The present invention also provides an image processing apparatus designed to achieve the above object, an image reading means for optically reading an image drawn on a sheet, and a wireless tag embedded in the sheet. A communication unit that communicates in a non-contact manner and reads management information about the image and surface identification information about the paper from the wireless tag; an image read by the image reading unit based on the surface identification information read by the communication unit; And determining means for associating with the management information read by the communication means.

  In addition, the present invention is an RFID tag embedded paper devised to achieve the above object, and is used in an image processing apparatus that performs at least one of image printing output and optical image reading, and by non-contact communication. A wireless tag-embedded paper in which a wireless tag capable of transmitting / receiving stored information to / from the outside is embedded, wherein the wireless tag has management information about a drawn image and a surface identification of a drawing surface of the drawn image Information is stored and held in association with each other.

  According to the image processing apparatus and the wireless tag embedded paper configured as described above, the wireless tag embedded in the paper stores the surface identification information about the paper in addition to the management information about the image drawn on the paper. . Here, “management information” is information for managing processing on an image, and specifically includes processing parameter information, image attribute information, and the like. The “surface identification information” is information for identifying each surface (for example, front / back) of the paper. By storing such surface identification information in the wireless tag, the storage information in the wireless tag, in particular, the management information about the image drawn on each surface of the paper is associated with the surface of the paper to be processed. It becomes possible.

  As described above, in the image processing apparatus and the wireless tag embedded paper according to the present invention, when the wireless tag is embedded in the paper, each surface of the paper and the wireless tag are stored by storing the surface identification information in the wireless tag. It is possible to associate with the information inside. Therefore, for example, even when the wireless tag stores different management information on the front and back sides of the sheet, the process specified by the management information can be appropriately executed for each of the front and back sides. That is, even when a plurality of surfaces of a sheet are to be processed, processing can be performed by appropriately using information stored in a wireless tag embedded in the sheet.

  Hereinafter, an image processing apparatus and a wireless tag embedded sheet according to the present invention will be described with reference to the drawings.

[Description of Configuration Example of Image Processing Device]
First, the configuration of the image processing apparatus will be described.

  FIG. 1 is an explanatory diagram showing an example of a schematic configuration of an image processing apparatus according to the present invention. An image processing apparatus 10 described as an example here is used as a copier or a multifunction machine that integrates a scan function, a print function, a FAX function, and the like. A unit 12, a printer unit 13, an information reader unit 14, a UI (User Interface) unit 15, and a control unit 16.

  The scanner unit 11 includes an image sensor including a CCD (Charge Coupled Device) and the like, and optically reads an image drawn on a sheet to obtain image data. The paper to be read by the scanner unit 11 includes a paper in which a wireless tag is embedded. Examples of the wireless tag include an RFID tag capable of recording n-bit digital information. However, the present invention is not necessarily limited to the RFID tag, and any other tag may be used as long as it can exchange information with the outside using wireless communication. Of course, the scanner unit 11 can cope with image reading from a sheet in which a wireless tag is not embedded.

  The document conveying unit 12 is composed of a DADF (Duplexing Automatic Document Feeder), and performs automatic feeding and automatic reversal of a sheet to be read by the scanner unit 11. By feeding the paper in the document conveying unit 12, the scanner unit 11 can read images from both sides of the paper. Images can be continuously read from a bundle of sheets made up of a plurality of sheets. In addition, the scanner unit 11 can also read images from both sides of the sheet by reversing the sheet in the document conveying unit 12.

  The printer unit 13 includes a printer engine that forms an image using a known electrophotographic technique, and prints out an image on a sheet. In addition, the printer unit 13 has a function of automatically feeding and automatically reversing a sheet to be printed, and these functions can perform print output on both sides of the sheet. . Note that the paper to be printed out by the printer unit 13 includes a paper in which a wireless tag is embedded, but the paper in which the wireless tag is not embedded can be printed out by the printer unit 13. Of course.

  The information reader unit 14 performs non-contact communication with a wireless tag embedded in the paper for which the scanner unit 11 reads an image or for a print output by the printer unit 13. Information is exchanged with the wireless tag. Specifically, it is conceivable to use an RFID reader that exchanges digital information with an RFID tag in a contactless manner. Examples of the location where the information reader unit 14 is provided include the vicinity of a document table (platen glass) included in the scanner unit 11 and the vicinity of a paper conveyance path included in the printer unit 13. However, it is not limited to these places, and any place in the image processing apparatus 10 may be used. This is because, depending on the communication capability (communication possible distance) of the information reader unit 14, information can be exchanged with the wireless tag embedded in the paper regardless of the arrangement location.

  The UI unit 15 is used by the user of the image processing apparatus 10 to perform an operation for inputting information or to output information to the user.

  The control unit 16 includes a CPU (Central Processing Unit) that executes a predetermined program, and performs operation control of the above-described units 11 to 15 and the entire image processing apparatus 10.

  Note that the scanner unit 11, the document conveying unit 12, and the printer unit 13 are not necessarily provided with both of them, and it is sufficient that at least one of them is provided. Therefore, the image processing apparatus 10 may be used as a scanner apparatus or a printer apparatus.

[Description of configuration example of wireless tag embedded paper]
Subsequently, a sheet handled by the image processing apparatus 10 having the above configuration, particularly a sheet in which a wireless tag is embedded will be described.

  As described above, n-bit digital information can be recorded on the wireless tag, but one of the contents of the digital information (stored information) is on the paper in which the wireless tag is embedded. There is management information about the image to be drawn. “Management information” is information for managing processing on an image. Specifically, parameter information, image attribute information, and other various setting information used when performing processing (data processing, print output processing, etc.) on image data obtained by reading an image on a sheet. In addition, security information for instructing whether or not to process image data, personal authentication information about a user, and the like may be used as management information.

  By the way, the stored information in the wireless tag is read out by the information reader unit 14 in a non-contact manner, but can be read from either the front or back side of the sheet because of wireless communication. Therefore, for example, when images are drawn on both sides of the paper, the management information read by the information reader unit 14 from the wireless tag embedded in the paper is the information about the image drawn on either side of the paper. It may become unclear whether it is a thing.

  Therefore, in addition to the management information described above, the wireless tag described in the present embodiment stores and holds surface identification information about the drawing surface of the drawn image in association with the management information. “Surface identification information” is information for identifying a drawing surface of a sheet. Specifically, information for discriminating the front and back surfaces of the paper is mentioned. However, it is not necessarily a distinction between the front and back surfaces, but may be information that identifies the drawing surface and the non-drawing surface of the image, or the print output surface of each sheet (both double-sided or single-sided) However, it may be information for specifying.

  Therefore, for example, in the case where images are drawn on both sides of the paper, the wireless tag has at least management information about the image drawn on one side and management about the image drawn on the other side. Information and surface identification information for identifying which surface the management information is for are stored and held. For example, if an image is drawn only on one side of the paper, at least the management information about the image drawn on the one side and whether the management information is for the front or back side The surface identification information for identifying is stored and held.

  Here, the surface identification information stored and held in the wireless tag will be described in more detail with a specific example.

[Description of first specific example of surface identification information]
FIG. 2 is an explanatory diagram illustrating a specific example of a drawn image. In the illustrated example, different images are drawn on the front and back surfaces of the paper 20. As the surface identification information about the paper 20 on which such an image is drawn, it is conceivable to use information relating to the characteristics of the image on the paper 20 that differs depending on the surface of the paper 20.

  The “information relating to image characteristics” includes information for specifying a characteristic attribute (for example, text / image classification, drawing time, etc.) and a characteristic layout configuration (for example, object arrangement) of the drawn image. Can be mentioned. Further, it may be information relating to the feature amount (for example, total data amount, data compression rate, average density value, dynamic range, existing edge amount, frequency component, number of types of existing color values) of the drawn image. Furthermore, if the drawing image includes text, the result of character recognition of the text (character information) may be used. Furthermore, it is also conceivable to use image data for thumbnail images obtained by reducing the entire drawn image or a part thereof. Of course, the information may be appropriately combined.

  In addition, “information relating to image characteristics” may be extracted from the entire drawing surface of the drawing image, but it is also possible to focus on a part of the drawing surface and extract from only that region. As the “partial region”, for example, a region where the density difference between pixels constituting the region is not large may be selected. Specifically, it is conceivable to select the image area 21 of the drawn image. If the density difference between pixels is small, such as the image area 21, the feature amount for each image tends to be clarified compared to a text area where the density difference between pixels is large. This is because the influence and the influence of image show-through can be suppressed. Furthermore, the “partial area” may be the specific area 22 in the image area 21. Specifically, the drawing images on the front and back surfaces of the paper or each surface of the paper constituting the paper bundle, particularly the image areas 21 in the drawing image are compared, and a difference (for example, a difference in density value) is found from the comparison result. It is conceivable to extract and select a remarkable area as the specific area 22. The size of the specific area 22 may be set in advance as a predetermined size. Further, in the case of limiting to the specific area 22, position information (for example, coordinate information) for specifying the position is managed together with “information regarding image characteristics” in the specific area 22. This means that a region having a remarkable feature can be selected as the specific region 22 without being limited in position.

[Description of second specific example of surface identification information]
FIG. 3 is an explanatory diagram showing another specific example of the surface identification information.
As the surface identification information, it is conceivable to use information related to the identification symbol 23 given in a different manner for each surface of the paper 20. Specifically, as shown in the figure, the identification symbol 23 having a different graphic shape is given to each front and back of the paper 20 or each surface of the paper 20 constituting the paper bundle, and the identification symbol 23 and the given surface are given. Information identifying the correspondence relationship is used as surface identification information. The identification symbol 23 is not limited to a graphic symbol as shown in the figure as long as it is given in a different manner depending on the surface of the paper 20, and other symbols (for example, an image represented by a barcode). Code).

  Such an identification symbol 23 is given to an area on the paper 20 that does not interfere with the drawn image in order to suppress the influence on the drawn image on the paper 20 as much as possible. Specifically, a header part (upper margin part) or a footer part (lower margin part), which is an area where an image is not drawn on the paper 20, can be considered as an application area of the identification symbol 23. Such a provision region and a provision position of the identification symbol 23 in the region are determined based on a preset setting. However, instead of setting a preset area as the grant area, the grant area may be determined in relation to the drawn image every time the identification symbol 23 needs to be given. That is, it is also conceivable to analyze the image data of the drawn image, extract a region having a predetermined area or more constituted by white pixel values, for example, as a region where no image exists, and determine the extraction region as the added region. In either case, the identification symbol 23 on the paper 20 is given to an inconspicuous area.

[Description of the third specific example of surface identification information]
FIG. 4 is an explanatory diagram showing still another specific example of the surface identification information.
As the surface identification information, it may be possible to use information related to the embedded position of the wireless tag 24 as viewed from the processing target surface of the paper 20. Specifically, as shown in the figure, if there is only one wireless tag 24 embedded in the paper 20, the embedded position of the wireless tag 24 is the paper as viewed from the front surface of the paper 20. Information identifying the lower left side of the paper 20 and information identifying the lower right side of the paper 20 as viewed from the rear side of the paper 20 are used as the surface identification information. For example, it is conceivable to specify the embedded position of the wireless tag 24 based on coordinate values on a sheet. However, as long as the drawing surface of the paper 20 can be identified and high accuracy is not required for position specification, the paper 20 is divided into a plurality of (for example, four) areas, and the divided areas (for example, the upper left) The embedded position of the wireless tag 24 may be specified depending on which region of the region, upper right region, lower left region, lower right region) the wireless tag 24 belongs to. Even when a plurality of wireless tags 24 are embedded in one sheet 20, it is possible to specify the embedded position of each wireless tag 24 by associating an identifier for identifying each wireless tag 24. Is possible.

FIG. 5 is an explanatory diagram showing a modification of the third specific example of the surface identification information.
As described above, when information related to the embedded position of the wireless tag 24 is used, in addition to the embedded position, information related to the drawing direction of the image on the paper 20 may be used as the surface identification information. Specifically, as information relating to the drawing direction of the image, information specifying whether the image is horizontally written (SEF) or vertically written (LEF) on the paper 20 as shown in the figure is used. As a result, the relationship between the vertical (top / bottom) direction of the drawing image on the paper 20 and the embedded position of the wireless tag 24 on the paper 20 becomes clear, so that the paper 20 is set when processing the paper 20 is performed. Regardless of the direction, the embedded position of the wireless tag 24 on the paper 20 can be correctly determined, and as a result, the drawing surface of the paper 20 can be accurately identified.

[Description of processing operation example in image processing apparatus]
Next, an example of a processing operation when the image processing apparatus 10 performs processing on the paper 20 in which the wireless tag 24 is embedded will be described.

First, an example of processing operation when the printer unit 13 prints an image on the paper 20 will be described.
In the image processing apparatus 10, a copy job in a mode corresponding to the wireless tag 24 is set after the paper 20 in which the wireless tag 24 is embedded (hereinafter referred to as “wireless tag embedded paper”) 20 is set in the paper feed tray of the printer unit 13. When a print job or FAX job is issued, the printer unit 13 receives image data relating to the job and prints out the image data. That is, the printer unit 13 forms an image based on the received image data, and prints the formed image onto the wireless tag embedded paper 20.
At this time, the information reader unit 14 prints out an image printed on the wireless tag embedded paper 20 with respect to the wireless tag 24 embedded in the wireless tag embedded paper 20 to be printed by the printer unit 13. Management information is written, and surface identification information about the RFID tag embedded paper 20 is written. The surface identification information may be performed by the control unit 16 that has received information from the printer unit 13 (for example, information on the image drawing surface of the paper).
As a result, the printer unit 13 prints out the image relating to the job, and the wireless tag embedded paper 20 in which the management information and the surface identification information of the image are written in the wireless tag 24 is discharged. . That is, the management information about the printed image and the print output surface of the image are output in association with each other by the stored information in the wireless tag 24.

Next, an example of processing operation when the scanner unit 11 reads an image from the wireless tag embedded paper 20 will be described.
In the image processing apparatus 10, the wireless tag embedded paper 20 is set on the document table of the scanner unit 11 or the paper feed tray of the document transport unit 12, and a copy of the image drawn on the wireless tag embedded paper 20 is copied. When a job or a scan job is issued, the scanner unit 11 performs optical image reading on the RFID tag embedded paper 20 and acquires image data from the paper 20.
At this time, the information reader unit 14 communicates with the wireless tag 24 embedded in the wireless tag embedded paper 20 to be scanned by the scanner unit 11, and reads stored information from the wireless tag 24. Do. That is, the information reader unit 14 reads management information and surface identification information from the wireless tag 24.
When the scanner unit 11 reads an image and the information reader unit 14 reads information, the control unit 16 scans the scanner based on these reading results, particularly the surface identification information read by the information reader unit 14. The image read by the unit 11 is associated with the management information read by the information reader unit 14.

The association may be performed as follows.
For example, in the case of the first specific example described above, the information relating to the feature of the image is used as the surface identification information. Therefore, the control unit 16 extracts the feature of the image from the image reading result by the scanner unit 11. Thus, the surface identification information that matches the extracted feature is searched for from the information reading result in the information reader unit 14. Then, the management information stored in the wireless tag 24 in association with the matched surface identification information is determined as the management information for the image read by the scanner unit 11.
Further, for example, in the case of the second specific example described above, since the identification symbol 23 is used as the surface identification information, the control unit 16 gives the drawing surface of the image from the image reading result by the scanner unit 11. The identified identification symbol 23 is extracted by a known pattern recognition technique or the like, and the surface identification information that matches the extracted identification symbol 23 is searched from the information reading result in the information reader unit 14. Then, the management information stored in the wireless tag 24 in association with the matched surface identification information is determined as the management information for the image read by the scanner unit 11.
Further, for example, in the case of the third specific example described above, since the embedded position information of the wireless tag 24 is used as the surface identification information, the control unit 16 is based on the information read result by the information reader unit 14. The embedded position of the wireless tag 24 on the paper 20 is recognized, and the surface identification information that matches the recognized embedded position is found from the information reading result by the information reader unit 14. Then, the management information stored in the wireless tag 24 in association with the matched surface identification information is determined as the management information for the image read by the scanner unit 11.

In the third specific example described above, if the information about the drawing direction of the image is used as the surface identification information in addition to the embedded position information of the wireless tag 24, the control unit 16 uses the image in the scanner unit 11. The drawing direction of the image is recognized from the read result. For example, in the case of an image including text, it is conceivable that this recognition is performed through determination of the image vertical (top / bottom) direction based on whether or not character recognition can be performed correctly. However, other known techniques may be used. When the drawing direction of the image is recognized, the matching surface identification information is searched based on both the recognition result and the recognition result of the embedded position of the wireless tag 24.
In this way, for example, the embedded position of the wireless tag 24 can be correctly recognized even when the wireless tag embedded paper 20 set in the scanner unit 11 or the document conveying unit 12 is upside down. There is no mistake in associating the drawing surface with the management information. The same applies to the case where the SEF output and the LEF output are mixed on the front and back surfaces of the paper 20 or on each surface of the paper 20 constituting the paper bundle. That is, if information relating to the drawing direction of the image is included as the surface identification information, it is very effective in improving the accuracy of associating the drawing surface of the image with the management information.

  Then, after associating the drawing surface of the image with the management information, the control unit 16 performs the image processing operation so as to perform the image processing operation on the image data obtained by reading the image with the scanner unit 11 while following the management information. Operation control of each part in the apparatus 10 is performed.

  As described above, according to the image processing apparatus 10 and the wireless tag embedded paper 20 in the present embodiment, in addition to the management information about the drawn image, the surface identification information about the image drawing surface is stored in the wireless tag 24. Since the information is stored, the storage information in the wireless tag 24, particularly the management information about the image drawn on each surface of the paper 20, and the surface of the paper 20 to be processed can be associated with each other.

Therefore, for example, even when the wireless tag 24 stores different management information on the front and back surfaces of the paper 20, it can be determined whether each management information is information on the front surface or the back surface of the paper 20. The process specified by the management information can be appropriately executed for each of the front and back surfaces.
Further, for example, even when the management information is read from each wireless tag 24 embedded in each sheet 20 constituting the sheet bundle, the association between each management information and each surface of each sheet 20 Therefore, appropriate processing can be executed for each surface. This means that even if information is simultaneously read from each wireless tag 24 on each sheet 20, appropriate processing can be executed on each side. Therefore, speeding up of information reading from the wireless tag 24 can be expected.
Further, for example, if timing control is performed so that information is read from the wireless tag 24 prior to image reading by the scanner unit 11, an image reading surface of the scanner unit 11 is an image drawing surface. It is also possible to determine whether or not. Therefore, unnecessary processing operations in the scanner unit 11 can be omitted, and it is possible to realize speeding up of processing and improvement of productivity.

  That is, according to the image processing apparatus 10 and the wireless tag embedded paper 20 described in the present embodiment, even when a plurality of surfaces of the paper 20 are to be processed, each surface of the paper 20 and the wireless tag 24 Since it can be associated with information, image processing can be performed by appropriately using the stored information in the wireless tag 24.

  In addition, although this embodiment demonstrated the suitable Example of this invention, this invention is not limited to the content. For example, as for the surface identification information, the first to third specific examples have been described, but it is also conceivable to use them in combination as appropriate. Thus, the present invention can be modified as appropriate without departing from the scope of the invention.
