Abstract

PROBLEM TO BE SOLVED: To provide a function which copies information on a surface of paper document being set to display related information but suppresses the succession of the display of the related information.SOLUTION: A system which copies a document comprises: scan means for obtaining scan data by scanning a manuscript of the document; storage means for storing management information which manages AR contents referred to by the document and electronic document data corresponding to the document; inspection means for inspecting whether or not the reference to the AR contents is set in the scan data; reference suppression means for suppressing the reference to the AR contents by the electronic document data when the inspection means detects that the reference to the AR contents is set in the scan data; and print means for printing out the electronic document data whose reference to the AR contents is suppressed.

Description

  The present invention relates to a document processing apparatus, a document processing system, a document processing method, and a document processing program.

A technique is known in which information related to a subject imaged by a camera is searched using a tablet terminal, a smartphone, or the like (hereinafter also referred to as a smart terminal), and the searched related information is displayed on the screen of the smart terminal. In augmented reality technology called Augmented Reality (hereinafter also referred to as AR), information related to the subject is searched and referenced from markers on the subject at the time of imaging, and the referenced content is converted into a real-world object imaged by the camera. Superimposed display.
If the technique is applied to a paper document as a subject, related information that is not written on the paper can be superimposed and displayed on the paper document by imaging the paper document. The superimposed display can reproduce a moving image (content that changes with time), and can express related information that cannot be provided by a paper document alone.

  As described above, when a paper document is used as a medium for displaying related information (content) that does not exist on the paper surface, the function performed by the copier must be changed. For example, a copy of a paper document also means a copy of related information superimposed on the paper document. Therefore, the copying machine determines whether the related information can be copied and suppresses the copy as necessary. It is expected to assume the function.

  Such a copy suppression function has been proposed in the past. Patent document 1 is one of them. Whether or not visualization output is possible in units of components such as figures and photographs is determined based on the data contents, and components determined to be prohibited from output are excluded from output targets.

JP 2010-130667 A

The technique disclosed in Patent Document 1 determines whether or not a component of a document can be printed on the basis of data contents, and prohibits printing in the case of failure. Components that are prohibited from printing are missing from the document, and the information itself is missing. If the information itself may be missing, this processing method is also appropriate, but there are cases where it is desired to suppress the copying of related information but to copy the data content itself.
For example, if the registration information is displayed as AR as related information from the driver's license, it is difficult to copy the information written on the driver's license to the AR display function of the registration information. Such as the case. In such a case, a copy function that copies only the information of the driver's license and does not take over the AR display function of the registration information is required. I do not want to suppress the copy of the driver's license information itself.
The present invention has been made in view of such problems, and an object thereof is to provide a function of copying information existing on a paper surface while suppressing inheritance of a related information display function.

  Accordingly, the present invention is a document processing apparatus, a scanning unit that scans a document to obtain scan data, an inspection unit that inquires an external device whether or not a reference to AR content is set in the scan data, Output means for outputting a document in which reference to the AR content is suppressed when it is detected by the inspection means that the reference to the AR content is set in the scan data.

  According to the present invention, it is possible to provide a document copying function that suppresses inheritance of related information display while copying information written on a paper document to a paper document set to display related information. Can do.

FIG. 1 is a diagram illustrating an example of a hardware configuration of a document processing system.
A document processing device 1016 is a device for processing a document such as a copying machine, and performs processing such as manuscript copying.

The CPU 101 is a microprocessor that performs operations for document copy processing, screen transition processing, printing processing, etc., logical determination, and the like, and controls each device connected to the bus.
The bus 107 transfers an address signal and a control signal for instructing each device to be controlled by the CPU 101. The bus 107 performs data transfer between devices.

The input unit 102 is a button, a touch panel, or the like, and the operator gives various instructions.
The display unit 103 is a liquid crystal display or the like, and displays a screen and the like described later.
The printing unit 104 is a printer or the like, which converts instructed data into various control languages or image data and outputs the converted data.
The scanner 105 performs processing such as reading and digitizing a paper document as a document.

The communication unit 106 is a network controller. Data exchange with the outside is performed via a wired or wireless communication path.
The ROM 108 is a read-only nonvolatile memory. The ROM 108 stores a boot program by the CPU 101, a system control program, various initial data referred to in various processes, and the like. The CPU 101 loads initial data into the RAM 109 when the system is started based on the boot program. Thereafter, the CPU 101 executes processing based on the control program. When the CPU 101 executes processing based on the control program, the function of the document processing system described later and the processing related to the flowchart described later are realized.

A RAM 109 is a readable / writable random access memory, and is used as a main memory for temporarily storing various data from each device. The RAM 109 stores various work areas for storing data necessary for processing, a stack necessary for processing, and various data whose values are changed during processing.
The DISK 1010 is a mass storage device and stores a large amount of data in a changeable manner. The DISK 1010 is composed of, for example, a hard disk. The control program executed by the CPU 101 and various initial data may be stored in the DISK 1010. In this case, the control program and various initial data are loaded into the RAM 109 used as the main memory as needed and executed or referred to. In this way, the program and initial data can be modified in the middle without being fixed, and a flexible system can be realized.

The server 1011 manages a document for performing AR display. The server 1011 is connected to the communication unit 106 via a wired or wireless communication path, and exchanges data as necessary. A server CPU 1012 and a server DISK 1013 exist in the server 1011.
The server CPU 101 is a microprocessor, and performs various operations such as AR content presence inspection processing, logical determination, and the like.

The server DISK 1013 is a mass storage device and stores a large amount of data in a changeable manner. The DISK 1013 is composed of, for example, a hard disk. A document management table, an object management table, an electronic document database, and the like, which will be described later, are stored in the server DISK 1013, and the contents are changed as needed.
A terminal 1014 is a terminal such as a tablet terminal that captures an image of a subject and AR-displays related information. The terminal 1014 is connected to the server 1011 via a wired or wireless communication path, and exchanges data as necessary. A terminal CPU 1015 exists in the terminal 1014.
The terminal CPU 1015 is a microprocessor, and performs various operations such as AR content presence inspection processing and screen transition processing, logical determination, and the like.

  The document processing system including such devices operates in response to various events from the input unit 102 or the like. When an interrupt from the input unit 102 or the like is supplied, an interrupt signal is sent to the CPU 101. Along with that, an event occurs, and the CPU 101 reads out various commands stored in the ROM 108 or RAM 109 in accordance with the event, and various controls are performed by the execution of the CPU 101.

Note that the CPU 101 of the document processing system according to the first embodiment functions as various units by executing a program. A control circuit such as an ASIC that operates in cooperation with the CPU 101 may function as these means. Further, these means may be realized by the cooperation of the CPU 101 and the control circuit. Further, the CPU need not be a single one, and may be a plurality.
In this case, a plurality of CPUs execute processing in a distributed manner. The plurality of CPUs may be arranged in a single computer, or may be arranged in a plurality of physically different computers. Note that the means realized by the CPU 101 executing the software may be realized by a dedicated circuit.

[Augmented reality display state]
FIG. 2 is an explanatory diagram of a state where a terminal such as a tablet terminal is performing augmented reality display. The related information (AR content) is referred to the image of the printed matter imaged by the imaging device using the marker (identification information) on the paper as a trigger, and is displayed superimposed on the electronic images 201 and 202. In this example, information related to a printed chart is displayed in a pop-up manner.

  The identification information on paper as a trigger is first considered a visualization marker such as a barcode or QR code (registered trademark), but is not limited thereto. Identification information for invisible information such as image feature information for individual objects on paper, image watermark information, text feature information for text objects, and layout information on how objects are laid out and configured over the entire page It can also be used as

  When invisible information is used, it is possible to configure a paper document that can display AR contents while maintaining the quality of the paper document, such as the artistry. The position where the related information is displayed is also shown here as an example of pop-up display, but it can also be configured to be displayed on an object on paper. When configured to display on paper, a display space for displaying related information can be saved.

[Use cases for document processing systems]
FIG. 3 is a diagram illustrating an example of a use case of the document processing system. When a paper document 301 is instructed to be copied to a document processing apparatus (illustrated by the multifunction machine 302), the document is scanned and digitized, and digitized data (hereinafter also referred to as electronic scan data) is stored in the server 303. To be sent for inspection. The server 303 checks whether there is a trigger (identification information) for displaying the AR content in the electronic scan data by searching the database 304 storing the document management information.

  If the identification information exists and the AR content indicated by the identification information is to be copy-suppressed, electronic document data corresponding to the electronic scan data is acquired from the database 304. The identification information of the electronic document data is modified, and the electronic document data is further rendered and returned as a document 305 to the MFP 302. The multifunction machine 302 prints out the document 306 that is not AR-displayed.

When the same paper document 301 as that scanned by the MFP 302 is imaged by the tablet terminal 307, the tablet terminal 307 requests the server 303 to inspect, and displays the AR by referring to the AR content stored in the database 304.
On the other hand, even if a document 306 not displayed on the AR is imaged on the tablet terminal 308 in the same manner and requested to be examined by the server 303, the AR content is not returned as a search result and the AR is not displayed.

[Example of document modification]
FIG. 4 is a diagram illustrating an example of document modification in the document processing system.
A document 401 is an example of a document. Objects such as text, images, and graphs are arranged in the document.
The document 402 is a modification example in the case where the AR display of the original document is performed using the watermark of the image as identification information. It is assumed that watermark information in the image of the document 402 has been modified from the document 401. However, the human eye cannot be identified as altered.
The document 403 is obtained by adding an extra object (in this case, a QR code (registered trademark)) to the document, assuming that the AR display of the original document is performed using the layout configuration of the entire document as identification information. This is an example. By intentionally adding extra objects in this manner, the layout of the entire document changes from the original layout, and the reference to the AR content is disconnected.
The document 404 also assumes a case where the AR display of the original document is performed using the layout configuration of the entire document as identification information. The layout is changed by intentionally deleting an extra object that has no information amount on the page. As a result, the layout configuration of the entire document changes, and the reference to the AR content is disconnected.
The document 405 also assumes that the layout configuration of the entire document is AR-displayed as identification information, but this does not increase or decrease the information amount of the paper document, but only changes the positional relationship between objects. In this example, the layout is changed. By changing the layout of the document in this way, it is possible to cut the reference to the AR content and suppress the display of the AR content (also referred to as reference suppression).

[Document Management Table and Object Management Table]
FIG. 5 is a diagram showing an example of the configuration of the document management table and the object management table in the document processing system.
FIG. 5A is a document management table. It manages a document, a reference relationship of AR contents to be displayed / reproduced from the document, and a method of suppressing the reference relationship. A document ID 501, a document feature amount 502, a suppression method 503, a content ID 504, an electronic document ID 505, and an object ID 506 are stored in association with each other. If the document ID 501 is specified, the document feature quantity 502, the suppression method 503, the content ID 504, the electronic document ID 505, and the object ID 506 corresponding to the document ID 501 are specified.
The document ID 501 stores ID information that uniquely identifies each document.
The document feature amount 502 stores a feature amount that characterizes each document. The document is identified by matching the stored feature quantity with the feature quantity extracted from the document imaged as a subject at the time of imaging.

  In the case of identifying by object rather than by document, the suppression method 503 describes a method of suppressing the AR content display of each document. For example, “layout change” for a document with document ID = 1, “dummy addition” for a document with document ID3, and “delete document” for a document with document ID = 5 are described as corresponding. ing.

In the suppression method, not only a method is specified, but a specific application method of the suppression method is described. For example, when the suppression method is “layout change”, it describes up to which object is arranged and how the layout is changed.
In the case where management is performed in units of objects rather than in units of documents (in the case of document ID = 2, 4, 6), information “every object” is stored in the suppression method 503.

  The content ID 504 stores the ID of the AR content displayed when identified by the identification information. Based on this information, the AR content is referred to and displayed or reproduced. When there is no corresponding content as a document, “0” is stored. When managed in object units, the value “0” is stored as the content ID of the document management table (in the case of document IDs-2, 4, and 6).

An electronic document ID 505 describes an ID in the electronic document database of electronic document data corresponding to the document. This links to the target electronic document data in the electronic document database. The electronic document data has a format that can be freely edited (changed) such as addition / deletion of an object, change of position / size, and the like. Also, it can be converted into printable data (rendering data) by rendering.
An object ID 506 stores an ID of an object included in the document on an object management table (described later). The object management table is drawn based on this information. Object IDs are stored for the number of objects included in the document.

FIG. 5B is an object management table. It manages the objects existing in the document, the reference relationship of AR contents displayed / reproduced in object units, and the method of suppressing the reference relationship.
The object ID 507 stores ID information that uniquely identifies each object. The object feature quantity 508 stores a feature quantity (such as an image feature quantity) that characterizes each object. The object is identified by matching the stored feature amount with the feature amount extracted from the object imaged as the subject at the time of imaging.

The suppression method 509 describes a method for suppressing the AR content display corresponding to each object.
For example, “Change watermark” for an object with object ID = 1, “Delete object” for an object with object ID = 2, and “Delete content” for an object with object ID = 3. Suppress display of AR content.
“Watermark change” means that watermark information such as an image is changed. “Delete object” means that the corresponding object is deleted from the document. “Content deletion” means that reference information from the object to the AR content is deleted from the object management table.
The suppression method is not limited to simply specifying a method, but specifically describes how the suppression method is applied. For example, when the suppression method is “change watermark”, it describes up to what value the watermark of which object is changed.

The content ID 5010 stores the ID of content to be AR displayed / reproduced from each object. If the ID information is deleted from this column, the content cannot be referred to. The “content deletion” means that the information in this column is cleared.
The above operation will be described below with reference to a flowchart.

[Operation of document processing device]
FIG. 6 is a flowchart showing an example of the operation of the document processing apparatus of the document processing system.
In step S601, the CPU 101 performs system initialization such as initialization of various parameters and display of an initial screen.
In step S602, the CPU 101 waits for an event to occur from the input unit 102 such as a touch panel.

When an event occurs, in step S603, the CPU 101 determines this event and branches to various processes depending on the type of event.
In step S604, the CPU 101 executes various processes according to the type of event. In FIG. 6, a plurality of branch destination processes corresponding to various events are collectively expressed in the form of step S604. The document copy process described in detail in FIG. 7 is a part of this branch destination. As other processing, although details are not described, there are generally widely performed processing such as screen control processing and printing processing.
In step S605, the CPU 101 notifies the processing result of each of the above processes and the end of the process, and displays the screen according to the instruction of each process. The processing in step S605 is processing that is normally performed widely, such as reflection on the screen display when normal processing is performed.

[Event response processing]
FIG. 7 is a flowchart illustrating an example of a document copy process that is a part of step S604. This process is performed when a paper document is placed on the document table and the operator instructs copying.
In step S <b> 701, the CPU 101 scans a paper document on the document table (also referred to as document scanning) and converts it into electronic data (electronic scan data).

  In step S702, if the document of the electronic scan data generated by scanning has the AR content identification information, the CPU 101 requests the server for the AR content inspection process described in detail in FIG. The server that has received this request process searches the electronic document data corresponding to the identification information in the electronic scan document, and if modification is necessary, the modified electronic document data is modified if modification is not necessary. Render the missing electronic document data and return the rendering data.

In step S703, the CPU 101 receives rendering data from the server. At this point, the rendering data is rendered data in which display / reproduction of the AR content is suppressed by modifying the management table or modifying the electronic document data as necessary.
In step S704, the rendering data is printed and output in the form of a paper document.

A flowchart showing an example of the operation of the server 1011 of the document processing system is shown in the same flowchart as FIG.
Differences from the description of FIG. 6 are the following three points.
The execution of each step is executed by the server CPU 1012.
The event that occurs in step S602 is various requests that occur via the network, such as AR content inspection processing.
An example of the process cited in step S604 is the AR content inspection process described in detail in FIG.

[Server operation]
FIG. 8 is a flowchart illustrating an example of the AR content inspection process, which is a process when the server 1011 receives electronic scan data. This is a process for checking whether or not AR content to be displayed / reproduced is set for the received electronic scan data, and if present, suppresses display / reproduction of the AR content.

In step S801, the server CPU 1012 inspects whether or not the reference to the AR content to be displayed / reproduced is set for the electronic scan data by performing the AR content presence inspection process described in detail in FIG. . If AR content exists, that is, if it can be detected, an electronic document ID is acquired.
In step S802, it is determined whether or not electronic document data exists. If the electronic document data does not exist, that is, if the electronic document ID = 0, the electronic scan data is returned as it is and returned. If the electronic document data exists, that is, if the electronic document ID is not 0, the process proceeds to step S803.

In step S803, the server CPU 1012 acquires electronic document data from the electronic document database based on the electronic document ID (also referred to as electronic document data acquisition).
In step S804, the server CPU 1012 determines whether AR content exists. If AR content does not exist, the process branches to step S8016. If AR content exists, the process proceeds to step S805.

In step S805, the server CPU 1012 sends information necessary for displaying a warning that there is AR content on the display unit 103 to the communication unit 106, and the CPU 101 displays the warning on the display unit 103 and gives an operator response. wait.
In step S <b> 806, the server CPU 1012 determines whether or not to suppress AR content based on an operator response input from the input unit 102 and sent from the communication unit 106. If it is not necessary to suppress, the process branches to step S8016. If it is necessary to suppress, the process proceeds to step S807. The number of confirmations of the presence of AR content from a printing device or the like is counted, and when the number exceeds a predetermined number, the association between the identification information and the AR content is changed to suppress display / reproduction of the AR content Also good.

In step S807, the server CPU 1012 refers to the document management table to check whether the suppression method in the document is for each object. If it is for each object, the process branches to step S808; otherwise, the process branches to step S8012.
In step S808, the server CPU 1012 refers to the document management table and identifies an object in the document.

In step S809, the server CPU 1012 refers to the object management table and acquires a suppression method for each object.
In step S8010, the server CPU 1012 modifies the document management table and the object management table as necessary in order to suppress the display / playback of the AR content according to the specified suppression method.
Specifically, for example, processing corresponding to “content deletion” is performed. “Content deletion” deletes the reference information (content ID 5010 in FIG. 5) from the corresponding object to the AR content from the object management table.

In step S8011, the server CPU 1012 performs processing for modifying electronic document data as necessary in order to suppress display / playback of AR content according to the specified suppression method.
Specifically, for example, the processing for modification is processing corresponding to “object deletion” and “watermark change”. If it is “delete object”, the corresponding object in the electronic document data is deleted from the document. If “change watermark”, the watermark information of an object such as an image in the electronic document data is changed. Thereafter, the process proceeds to step S8016.

In step S8012, the server CPU 1012 determines whether the suppression method specified in the document is “change layout”. If the layout is changed, the process advances to step S8013. If not, the process branches to step S8014.
In step S8013, the server CPU 1012 changes the layout of the electronic document data as specified in the suppression method, and branches to step S8016.

In step S <b> 8014, the server CPU 1012 corrects the document management table as necessary according to the suppression method. For example, when the suppression method is “document deletion”, the document with the corresponding document ID is deleted from the document management table.
In step S8016, the server CPU 1012 renders the electronic document data modified (or not modified) in this way, returns the rendered data (rendering data), and returns.

[AR content existence inspection process]
FIG. 9 is a flowchart illustrating an example of the AR content presence inspection process in step S801 in the server 1011. This is a process for inspecting whether AR content to be displayed / reproduced is designated in a document of designated electronic scan data.
In step S901, the server CPU 1012 extracts a document feature amount from the electronic scan data.

In step S902, the server CPU 1012 searches the document management table using the document feature amount as a query.
In step S903, the server CPU 1012 determines whether it is registered in the document management table. If registered, the process branches to step S905. If not registered, the process branches to step S904.

In step S904, the server CPU 1012 determines that there is no AR content. In step S905, the server CPU 1012 sets electronic document ID = 0 because no electronic document is found, and returns.
In step S906, the server CPU 1012 determines that there is AR content. In step S907, the server CPU 1012 acquires and outputs the electronic document ID of the found document. Then return.
