Abstract

To enable protection of privacy when a scanning result of a document is viewed, without complicated work.SOLUTION: An MFP cooperation service 120 acquires a history which becomes an editing object of a learning content, of the history indicating a scanning result of a document with which a result of form learning is associated. The MFP cooperation service 120, when a user who becomes an editor, and the user who has instructed the scan of the document indicated by the history which becomes an object coincide with each other, based on the acquired history, extracts an image of the document corresponding to the scanning result indicated by the history. The MFP cooperation service 120, when the user who becomes the editor, and the user who has instructed the scan do not coincide with each other, extracts the image of the document saved in a storage destination in which the user who becomes the editor has an access right, of the storage destination in which the image of the document corresponding to the scanning result indicated by the history is saved. The MFP cooperation service 120 is controlled so that the image of the extracted document is outputted to a predetermined output destination.SELECTED DRAWING: Figure 19

Description

This disclosure relates to an image processing system, a control method for an image processing system, and a program.

There is a known technology that recognizes the format of a document scanned by an image processing device such as an MFP by applying a process such as OCR (Optical Character Recognition) to the document. As a function that uses such a technology, a function has been proposed that extracts the components such as characters that make up the document to be scanned according to the format of the document, and assigns information indicating the components as file attributes (attribute values) to data corresponding to the scan results and manages them. As a function related to such a function, a function for editing the file attributes assigned to the data has also been proposed. Such a function may be provided with an additional function of displaying an image of the document to be scanned on a screen so that the user can visually confirm the document.

On the other hand, there may be a situation where the documents to be scanned contain information that should be kept confidential. In such a situation, it may be desirable to appropriately manage the confidential information. Patent Document 1 discloses a technique for saving a document template, setting the area to be extracted in the template as metadata, and then setting access rights to the metadata. With this mechanism, when a user who does not have access rights to the metadata views the document data, it is possible to prevent the user from viewing the area where the metadata is set by masking the metadata.

JP 2019-082887 A

On the other hand, the method disclosed in Patent Document 1 requires users to register templates in advance and then set access rights to metadata one by one, which is time-consuming for users.

In consideration of the above problems, the present invention aims to make it possible to protect privacy when the results of a document scan are viewed without the need for cumbersome work.

The image processing system according to the present invention includes an acquisition means for acquiring a history showing a scan result of a document associated with a learning result of the document format, the history being the subject of editing of the learning content, an extraction means for extracting an image of the document to which a first user who is the subject of the editing has access rights based on the acquired history, and an output control means for controlling the output of the extracted image of the document to a predetermined output destination, the history including information indicating a second user who instructed the scan of the document corresponding to the scan result indicated by the history, the extraction means extracting an image of the document corresponding to the scan result indicated by the history when the first user and the second user whose information is included in the target history match, and extracting an image of the document stored in a storage destination to which the first user has access rights from among the storage destinations in which the image of the document corresponding to the scan result indicated by the acquired history is stored when there is no history in which the first user and the second user match.

The present invention makes it possible to protect privacy when scanning a document without the need for cumbersome procedures.

A preferred embodiment of the present disclosure will be described in detail below with reference to the attached drawings. Note that in this specification and drawings, components having substantially the same functional configuration are designated by the same reference numerals to avoid redundant description.

<Definition of terms>
Among the terms used in this disclosure, definitions of particularly characteristic terms are summarized below.
The term "scan job" refers to a job for processing image data generated as a result of scanning an original document using an image processing device such as an MFP (Multifunction Peripheral).
The term "file attribute" refers to attribute values of an output file, such as a file name or metadata, that are assigned to an output file generated by various jobs including a scan job.
"Form learning" refers to an information processing device learning the characteristics of a form format (template) such as a ledger or a slip. By performing form learning, the information processing device determines whether a format similar to (e.g., having similar characteristics) a format applied to a document previously processed is applied to a newly input document (form). In addition, the information processing device learns, through form learning, coordinates indicating the position and size of characteristic parts (e.g., parts defined as file attributes) of a format applied to a document previously processed, which are extracted from the document previously processed.

First Embodiment
A first embodiment of the present disclosure will be described below. For convenience, in this embodiment, it is assumed that the MFP scans a document in response to an instruction from a user, extracts file attributes, and transmits the file attributes to a predetermined storage destination, and then performs form learning based on the extraction results. It is also assumed that the content of form learning related to the extraction of file attributes from the document scan results is edited in response to an instruction from an administrator user.

(overall structure)
An example of the overall configuration of an image processing system according to the present embodiment will be described with reference to FIG. 1. The image processing system includes an MFP 110, an MFP linkage service 120, a cloud storage 130, and a PC (Personal Computer) 140. Each of the MFP 110 and the PC 140 is connected to the Internet via a LAN (Local Area Network). This allows each of the MFP 110 and the PC 140 to access a server that provides various network services on the Internet. Note that the network configuration shown in FIG. 1 is merely an example, and as long as each component of the image processing system according to the present embodiment is connected to be able to communicate with each other, the network configuration for this purpose is not particularly limited.

The MFP 110 is a schematic representation of a multifunction peripheral having multiple functions such as a scanner, a printer, etc. The MFP 110 corresponds to an example of an image processing apparatus according to the present embodiment.
The MFP cooperation service 120 is a schematic representation of a service having a function of holding image data corresponding to the results of scanning an original (e.g., a document) by an MFP, and a function of transferring the image data to another service capable of storing data, such as a so-called storage service, etc. In the image processing system according to this embodiment, the MFP cooperation service 120 also edits the contents of the form learning related to the extraction of file attributes from the results of scanning a document.
Cloud storage 130 is a schematic representation of a service having a function of acquiring and storing various data (various files) from other devices via a network such as the Internet. Cloud storage 130 may also provide an interface for accessing the stored data (e.g., for referencing the data) via a web browser or the like.
The PC 140 is a schematic representation of a terminal device that enables a user to utilize the MFP linkage service 120. The PC 140 can be realized by an information processing device that is capable of communicating with other devices via a network, such as a PC, a tablet terminal, or a smartphone.

The configuration shown in FIG. 1 is merely an example, and does not necessarily limit the configuration of the image processing system according to this embodiment. As a specific example, the MFP 110 may also serve as the MFP linkage service 120. The MFP linkage service 120 may also be realized by a server on a network other than the Internet, such as a LAN. The cloud storage 130 may be replaced by a mail server, etc., so that image data corresponding to the results of scanning a document can be attached to an email and transferred to another device. In the example shown in FIG. 1, the PC 140 is connected to a LAN, but may also be connected to the Internet.

(MFP Hardware Configuration)
2, an example of the hardware configuration of the MFP 110 will be described. The MFP 110 includes a control unit 210, an operation unit 220, a printer unit 221, a scanner unit 222, and a modem 223.
The control unit 210 is a schematic diagram of components that control the MFP 110. The control unit 210 includes a central processing unit (CPU) 211, a read only memory (ROM) 212, and a random access memory (RAM) 213. The control unit 210 also includes a hard disk drive (HDD) 214, an operation unit I/F 215, a printer I/F 216, a scanner I/F 217, a modem I/F 218, and a network I/F 219. The above-mentioned series of components of the control unit 210 are connected to each other via a bus so as to be able to transmit and receive information to and from each other.

The CPU 211 controls the overall operation of the MFP 110. As a specific example, the CPU 211 reads out a control program stored in the ROM 212, and executes processes related to the realization of various functions of the MFP 110, such as reading, printing, and communication, and controls the functions. The RAM 213 is used as a temporary storage area such as the main memory or work area of the CPU 211. Note that in this embodiment, one CPU 211 uses one memory (RAM 213 or HDD 214) to realize the processes described below with reference to Figures 5, 17, 19, and 20, but this does not necessarily limit the configuration of the MFP 110. As a specific example, each process may be realized by having multiple CPUs and multiple memories work together.

The HDD 214 serves as a storage area for storing various data such as image data, various programs, etc. Note that instead of the HDD 214, other auxiliary storage devices such as a solid state drive (SSD) may be used.
The operation unit I/F 215 is an interface that connects the operation unit 220 and the control unit 210. The operation unit 220 is an input interface for receiving operations, inputs, and instructions from a user. The operation unit 220 can be realized by an input device such as a touch panel or a keyboard, for example.
The printer I/F 216 is an interface that connects the printer unit 221 and the control unit 210. Image data used for printing is transferred from the control unit 210 to the printer unit 221 via the printer I/F 216. The printer unit 221 prints an image indicated by the transferred image data on a recording medium such as paper.
The scanner I/F 217 is an interface that connects the scanner unit 222 and the control unit 210. The scanner unit 222 reads an original placed on an original tray or an ADF (Auto Document Feeder) (not shown) to generate image data, and inputs the image data to the control unit 210 via the scanner I/F 217.
The MFP 110 can realize a so-called copy function by printing out image data generated by a scanner unit 222 from a printer unit 221 .

Furthermore, the MFP 110 is also capable of transmitting image data generated by the scanner unit 222 as a file or by email.
The modem I/F 218 is an interface that connects the modem 223 to the control unit 210. The modem 223 transmits and receives image data by facsimile communication with a facsimile device on a PSTN (Public Switched Telephone Network).
The network I/F 219 is an interface for connecting the control unit 210 (MFP 110) to a network such as a LAN. By using the network I/F 219, the MFP 110 transmits various data such as image data and various information to each service on a network such as the Internet, and receives various data and information from the service.

(Hardware configuration of server providing MFP linkage service)
An example of the hardware configuration of a server that provides the MFP collaboration service will be described with reference to Fig. 3. The server that provides the MFP collaboration service 120 includes a control unit 310 that controls the operation of the server.

The control unit 310 includes a CPU 311, a ROM 312, a RAM 313, a HDD 314, and a network I/F 315. The above-mentioned series of components of the control unit 310 are connected via a bus so as to be able to transmit and receive information to and from each other.
The CPU 311 controls the overall operation of the server, including operations related to the realization of the MFP linkage service 120. As a specific example, the CPU 311 reads out a control program stored in the ROM 312, and executes processes related to the realization of various functions of the server (for example, functions provided by the MFP linkage service 120) and controls the functions. The RAM 313 is used as a temporary storage area such as the main memory or work area of the CPU 311.
The HDD 314 serves as a storage area for storing various data such as image data, various programs, etc. Instead of the HDD 314, other auxiliary storage devices such as an SSD may be used.

The network I/F 315 is an interface for connecting the control unit 310 (a server that provides the MFP cooperation service 120) to a network such as the Internet.
The server that provides the MFP cooperation service 120 accepts processing requests from other devices (such as the MFP 110) via the network I/F 315, and transmits and receives various data and information to and from the devices.

The hardware configuration shown in FIG. 3 is not limited to the MFP linkage service, but can also be applied to servers related to the provision of other services, such as cloud storage 130.

(Software configuration of image processing system)
An example of the software configuration of the image processing system according to the present embodiment will be described with reference to FIG. 4, focusing in particular on the configuration of the MFP 110 and the MFP cooperation service 120.

First, an example of the software configuration of the MFP 110 will be described. The components of the MFP 110 are mainly divided into a native function unit 410 and an additional function unit 420. The components included in the native function unit 410 may correspond to components corresponding to functions that are standardly provided in the MFP 110. In contrast, the components included in the additional function unit 420 may correspond to components corresponding to functions added to the MFP 110 (for example, additionally installed applications, etc.). The additional function unit 420 is realized by, for example, an application based on a program language such as JAVA (registered trademark), making it possible to easily add functions to the MFP 110. In addition, the MFP 110 may be provided with other additional functions not shown.

The native function unit 410 includes a scan execution unit 411 and an image data storage unit 412. The additional function unit 420 includes a display control unit 421, a scan instruction unit 422, and a linkage service request unit 423.

The display control unit 421 displays a UI (User Interface) screen for accepting operations from a user on a predetermined output device such as a liquid crystal display unit having a touch panel function of the operation unit 220 in the MFP 110. The UI screen is used, for example, to input authentication information used for accessing the MFP linkage service 120, to specify scan settings, to accept an operation to start scanning, to display a preview image, and the like.
The scan instruction unit 422 requests the scan execution unit 411 to execute a scan process of an original (document) in response to an instruction from the user received via the UI screen. At this time, the scan execution unit 411 may notify the scan execution unit 411 of information indicating the scan settings specified by the user.

The scan execution unit 411 receives a scan request from the scan instruction unit 422. At this time, the scan execution unit 411 may obtain information indicating scan settings from the scan instruction unit 422. The scan execution unit 411 controls the scanner unit 222 via the scanner I/F 217 in accordance with the received scan request, thereby causing the scanner unit 222 to execute processing related to scanning an original (document). As a result, for example, an original placed on a platen glass is read (scanned) by the scanner unit 222. The scan execution unit 411 generates data of an image of the original (hereinafter also referred to as scanned image data) based on the result of reading the original (scan result) by the scanner unit 222. The scan execution unit 411 outputs the generated scanned image data to the image data storage unit 412. The scan execution unit 411 also notifies the scan instruction unit 422 of an identifier (hereinafter also referred to as scanned image identifier) for uniquely identifying the generated scanned image data. The scanned image identifier is information capable of uniquely identifying an image corresponding to the result of scanning a document by the MFP 110, and may be composed of, for example, numbers, symbols, alphabets, and the like.
The image data storage unit 412 stores the scan image data output from the scan execution unit 411 in a predetermined storage area (for example, the HDD 214).

The scan instruction unit 422 uses the scan image identifier notified by the scan execution unit 411 to obtain the scan image data corresponding to the scan image identifier from the image data storage unit 412. The scan instruction unit 422 requests the cooperation service request unit 423 to request the MFP cooperation service 120 to process the obtained scan image data.

The linked service request unit 423 requests various processes from the MFP linkage service 120. As a specific example, the linked service request unit 423 may request the linked service request unit 423 to log in, analyze a scanned image, transmit a scanned image, and the like. Note that as long as it is possible to realize an exchange between the MFP 110 (linkage service request unit 423) and the MFP linkage service 120, the method for doing so is not particularly limited. As a specific example, the exchange between the MFP 110 and the MFP linkage service 120 may be realized by an architecture called REST (Representational State Transfer). In this case, a protocol called SOAP (Simple Object Access Protocol) may be used for the exchange between the MFP 110 and the MFP linkage service 120.

Next, an example of the software configuration of the MFP collaboration service 120 will be described. The MFP collaboration service 120 includes a request control unit 431, an image processing unit 432, a cloud storage access unit 433, a data management unit 434, and a display control unit 435. The MFP collaboration service 120 may also include an email sending unit 436.

The request control unit 431 executes various processes related to receiving requests from external devices. For example, the request control unit 431 waits in a state in which it can receive requests from external devices, and upon receiving a processing request, instructs the image processing unit 432, cloud storage access unit 433, data management unit 434, etc. to perform processing as appropriate in response to the request.

The image processing unit 432 performs image recognition and processing such as character region analysis, OCR (Optical Character Recognition), similar form determination, image rotation and tilt correction, etc. The similar form determination will be described in detail later in conjunction with the explanation of FIG. 5.

The cloud storage access unit 433 makes processing requests to the cloud storage. Cloud services generally expose a variety of interfaces for saving data in cloud storage and accessing saved data using an architecture called REST or a protocol called SOAP. The cloud storage access unit 433 uses the exposed cloud storage interface to operate the cloud storage.

The data management unit 434 holds various information (e.g., user information) and various data (e.g., setting data, etc.) that are managed by the MFP collaboration service 120. The data management unit 434 also holds the scan history, which will be described later.

The display control unit 435 presents various information to the user via a terminal device (e.g., a PC or a mobile terminal) connected via a network such as the Internet. As a specific example, the display control unit 421 receives a request from a web browser running on the terminal device and returns screen configuration information (HTML, CSS, etc.) used by the web browser to display a screen to the web browser. The web browser forms a screen using the screen configuration information returned from the display control unit 435 and displays the screen in a specified output area. This configuration allows the user to check user information registered in the MFP linkage service 120 and change settings when scanning a document via the screen displayed by the web browser.

The email sending unit 436 sends various information and data to other devices by using email. For example, the email sending unit 436 may send at least a portion of the various information and data managed by the MFP collaboration service 120 to other devices by using email.

(Overall processing flow)
With reference to Figures 5 to 16, an example of the overall processing flow of the image processing system according to this embodiment will be described, focusing on the processing flow between each device when image data of a document scanned by MFP 110 is converted into a file and sent to cloud storage.

In a normal state (e.g., immediately after startup or in a standby state), MFP 110 displays a main screen in a specified output area (e.g., on a touch panel) for receiving from the user the specification of a function to be used from a series of functions provided by MFP 110. For example, buttons corresponding to each function are displayed in an array on the main screen, and when a certain button is operated by the user, a process corresponding to the function associated with that button is executed.

For example, FIG. 6 is a diagram showing an example of a main screen 600 of the MFP 110. In the example shown in FIG. 6, buttons corresponding to the respective functions of "copy," "scan," and "scan and save to cloud storage" are displayed on the main screen 600. The copy function and the scan function correspond to functions that are standardly provided in the MFP 110. In contrast, the scan and save to cloud storage function corresponds to an additional function, and is added, for example, by installing an additional application (hereinafter also referred to as a scan app). In addition, by adding the scan and save to cloud storage function with the installation of the scan app, a button 601 corresponding to the function is displayed on the main screen 600. Note that when the button 601 is pressed, the series of processes shown in FIG. 5 is started.

In S501, the scan application displays a login screen for receiving input of authentication information for accessing the MFP cooperation service 120 from the user in a predetermined display area.
7 is a diagram showing an example of a login screen 700 displayed on the MFP 110. The login screen 700 displays a login button 701 and input areas 702 and 703. The input area 702 is an interface for accepting, from the user, an input of a user name to be used in the login process. The input area 703 is an interface for accepting, from the user, an input of a password to be used in the login process. The login button 701 is an interface for accepting, from the user, an instruction to execute login processing using the user name input in the input area 702 and the password input in the input area 703.

When the login button 701 is pressed, the login process shown as S502 in FIG. 5 is executed based on the user name entered in the input area 702 and the password entered in the input area 703.
Specifically, in step S<b>502 , the MFP 110 transmits a login request including the user name input in the input field 702 and the password input in the input field 703 to the MFP cooperation service 120 .
In S503, the MFP cooperation service 120 verifies whether or not the user name and password included in the login request received from the MFP 110 match the user name and password of the user registered in the MFP cooperation service 120. When the MFP cooperation service 120 confirms that the user name and password included in the login request match the user name and password of the registered user, it returns an access token associated with the user name to the MFP 110. Thereafter, when various requests are made from the MFP 110 to the MFP cooperation service 120, the access token is sent together, and the user to be processed is identified by the access token. Note that the method of user authentication is not particularly limited, and it is possible to apply a generally known method such as Basic authentication, Digest authentication, and authorization using OAuth.

In S504, the MFP 110 displays a scan setting screen in a predetermined display area.
8 is a diagram showing an example of a scan setting screen 800 displayed on the MFP 110. The scan setting screen 800 includes a scan start button 801 and input areas 802 and 803. The input areas 802 and 803 are interfaces for receiving designation of settings related to scanning an original from a user. Specifically, the input area 802 is an input area for receiving designation of a setting for scanning an original in black and white or in color (hereinafter also referred to as color setting). Furthermore, the input area 803 is an input area for receiving designation of a resolution setting when scanning an original.

When the scan start button 801 is pressed, scanning of the document is executed based on the settings specified in the input areas 802 and 803, as shown in S505 in FIG.
Specifically, in S505, the MFP 110 scans an original (document) placed on the platen glass or the ADF to generate scanned image data that is a digitalized version of the original.
In S506, the MFP 110 transmits the scan image data generated in S505 to the MFP cooperation service 120, and requests the MFP cooperation service 120 to analyze the scan image indicated by the scan image data.
With this, the processing on the MFP 110 is completed.

When the MFP collaboration service 120 receives the request to analyze the scanned image in S506, the MFP collaboration service 120 starts analyzing the scanned image that is the target of the analysis request in S507. The analysis of the scanned image is performed by the image processing unit 432. The MFP collaboration service 120 also holds identification information (e.g., processId) for uniquely identifying the analysis performed by the image processing unit 432 without waiting for the image analysis process to end. For example, FIG. 9 is a diagram showing an example of the identification information. Note that in the following description, it is assumed that the processId shown in FIG. 9 is used as the identification information.
As shown in S508, the MFP cooperation service 120 uses the processId held in S507 to check the status of the image analysis process executed by the image processing unit 432.

In S509, the image processing unit 432 of the MFP cooperation service 120 analyzes an area of text information (hereinafter also referred to as a text area) that exists in the image to be analyzed.
In S510, the image processing unit 432 executes processing related to recognition of characters in the character area analyzed in S509 (hereinafter, also referred to as character recognition processing).
In S511, the image processing unit 432 compares the layout information indicating the position and size of the character area in the image to be analyzed (in other words, in the scanned document) with the layout information of the image of a document scanned in the past. Based on the result of the comparison, the image processing unit 432 determines whether a document having a similar layout of character areas to the image corresponding to the current scan result has been scanned in the past. This process is also called similar form determination. Note that the information of the scanned image corresponding to the past scan result used in the similar form determination is saved by the process of S520 (described later) executed in the past (i.e., the process equivalent to S520 executed previously).

In S508, the MFP cooperation service 120 uses the processId held in S507 to check the processing status of the image analysis by the image processing unit 432. This checking of the processing status of the image analysis by the image processing unit 432 is performed periodically (e.g., at intervals of several hundred milliseconds to several milliseconds) until the image analysis by the image processing unit 432 is completed (e.g., until a response indicating the completion of image processing is obtained), for example.
When the image processing unit 432 receives the request to check the processing status in S508, it checks the status of the processing corresponding to the specified processId. If the target processing is currently being executed, the image processing unit 432 returns a response indicating that the processing is currently being executed to the request source.

For example, Fig. 10A is a diagram showing an example of a response returned from the image processing unit 432 when the process corresponding to the specified processId is being executed (i.e., a response indicating that the process is being executed), and Fig. 10B is a diagram showing an example of a response returned from the image processing unit 432 when the process corresponding to the specified processId has been completed (i.e., a response indicating that the process has been completed).
In the example shown in FIG. 10, information (e.g., a character string) indicating the processing status is stored as the value of the "status" attribute for the response. Specifically, as shown in FIG. 10(A), when the value of the "status" attribute is "processing", it indicates that the target processing is being executed. As another example, as shown in FIG. 10(B), when the value of the "status" attribute is "completed", it indicates that the target processing is in a completed state. As another example, when the target processing is abnormally terminated due to the occurrence of an error or the like, "failed", indicating that an error has occurred, may be stored as the value of the "status" attribute.
When the process is completed (status is completed), the response sent back includes information such as the results of analyzing the scanned image as well as the status.

In S512, when the MFP collaboration service 120 detects the completion of the image analysis process by the image processing unit 432, in S513, it acquires information indicating the result of the image analysis (hereinafter also referred to as result information) based on the information included in the response. As a specific example, in the case of the example shown in FIG. 10(B), it is possible to acquire the result information from a URL ("ocrResultUrl" or "matchingResultUrl") included in the response.

In S514, the PC 140 accesses the MFP linkage service 120 based on instructions received from the user via a web browser, etc. This enables the user to, for example, check the scan job processed in S507 to S513 via the PC 140 and to set file attributes, which will be described later, etc.
Specifically, in S<b>514 , the PC 140 accepts input of authentication information such as a user name and password from the user, and transmits a login request including the authentication information to the MFP cooperation service 120 .
In S515, the MFP collaboration service 120 verifies whether or not the authentication information included in the login request received from the PC 140 matches the authentication information of a user registered in the MFP collaboration service 120. If the MFP collaboration service 120 confirms that the authentication information included in the login request matches the authentication information of the registered user, it returns an access token associated with the user name to the PC 140. Thereafter, when various requests are made from the PC 140 to the MFP collaboration service 120, this access token is sent together, and the user to be processed is identified by the access token.

In S516, PC 140 sends a request to MFP collaboration service 120 to obtain a scan job from MFP collaboration service 120. MFP collaboration service 120 returns a list of stored scan jobs to PC 140 as a response to the request from PC 140. In the example shown in FIG. 5, the scan job for which image processing has been completed in S508 to S513 is stored in MFP collaboration service 120, and therefore the scan job is included in the list of scan jobs returned to PC 140. PC 140 then presents the list of scan jobs obtained from MFP collaboration service 120 to the user.

Figure 18 is a diagram showing an example of a scan job list screen 1800 displayed via PC 140 as a result of the processing of S516. The scan job list screen 1800 includes a display area 1801. Display area 1801 displays list items corresponding to one scan job. One item is configured to include information such as a thumbnail image, scan date, and storage destination. This information is generated, for example, based on the results of image processing performed on an image corresponding to the document scan results and the results of past form learning. The processing related to the generation of this information will be explained in detail below.

Figure 13 shows an example of an image represented by scanned image data. In the following, various explanations will be given based on the scanned image data corresponding to the image shown in Figure 13. Table 1 shown below shows the coordinates of the area of each recognized character and the data (character string) of the character when character area analysis and character recognition are performed on the scanned image data corresponding to the image shown in Figure 13.

14 is a diagram showing an example of data indicating the result of character recognition obtained from the MFP cooperation service 120. "ImageWidth" indicates the position in the X direction (horizontal direction) of the image to be analyzed in terms of the number of pixels. "ImageHeight" indicates the position in the Y direction (vertical direction) of the image to be analyzed in terms of the number of pixels. "Regions" includes coordinate information of the character region extracted from the image to be analyzed and an array of character information.
"Rect" indicates the coordinates of each extracted character area. "x" and "y" indicate the X and Y coordinates of the upper left corner of the area in pixels. "Width" and "Height" indicate the X and Y widths of the area in pixels. "Text" indicates characters extracted as a result of character recognition performed by OCR on the character area of "rect". This "rect" and "text" information is included for all character areas in the analyzed scanned image (some parts are omitted in FIG. 14).

FIG. 15 is a diagram showing an example of data showing the result of similar form determination obtained from the MFP linkage service 120. "matched" stores a value indicating whether or not an image of a previously scanned form similar to the image to be analyzed was extracted by the similar form determination. "formId" stores a value that uniquely indicates the form when a similar form image is extracted, and stores a value used when learning the input information of the image corresponding to the scan result in S518 when a similar form image is not extracted. "matchingScore" stores a value indicating how similar the image of a similar form was when it was extracted. "matchingScore" represents the degree of match between the image arrangement information corresponding to the past scan result and the image arrangement information corresponding to the current scan result as a real value ranging from 0 to 1, and the larger the value, the more similar the form is. In the following, the value set in "matchingScore" is also referred to as "confidence level". In other words, the confidence level is an index that indicates the degree of certainty that the format of the target document (form) matches the format of the document (form) being compared.

"rectInfoArray" stores information indicating the character area of the image to be analyzed this time, which corresponds to the character area used by the user when setting the file name for a similar form. In the example shown in FIG. 15, it is assumed that the file name is set using the words "quote" and "Shinagawa Co., Ltd." for the scanned image data based on the scan result executed in the past illustrated in FIG. 13, and then form learning is performed. In addition, it is assumed that the scanned image data based on the scan result executed this time illustrated in FIG. 16 and the scanned image data illustrated in FIG. 13 are subjected to similar form determination, and the scanned image data illustrated in FIG. 16 is determined to correspond to the similar form of the scanned image data illustrated in FIG. 13. In addition, the example shown in FIG. 15 shows a state in which the information input to the scanned image data illustrated in FIG. 13 is stored as information to be automatically input.
First, from the information stored in the data management unit 434 of the MFP linkage service 120 by the form learning, the coordinate information of the character area corresponding to the previously set "Estimate" and "Shinagawa Co., Ltd." and the character area that partially overlaps are identified. For example, Fig. 12 is a diagram showing an example of information used in the above form learning. As shown in Fig. 12, the coordinate information of the partially overlapping character area and the characters are stored in "text" in "rectInfoArray" (to be described later).

"Key" stores a value that uniquely indicates the character area used for automatic input. "Region" stores coordinate information for the character area and the characters extracted as a result of character recognition targeting that character area. "Rect" indicates the coordinates of one extracted character area. "X" and "Y" indicate the X and Y coordinates of the upper left corner of the area in pixels. "Width" and "Height" indicate the X and Y widths of the area in pixels. "Text" indicates the characters extracted as a result of character recognition performed by OCR on the character area indicated by "Rect".

In "metadataArray", information indicating the order of character areas used for file attributes for automatically inputting file attributes and information indicating where delimiters are inserted are stored. In "key", a value that uniquely indicates the setting value set for the document to be scanned is stored. In "keyType", a value indicating the type of setting value specified in "key" is stored. For example, when used for a file name, "filename" is stored as the value for "key", and "filename" is stored as the value for "keyType". In "value", information on character areas and delimiters used for the value of "key" is stored. That is, in the example shown in FIG. 15, it is shown that the file name is automatically input in the following order: the area with "key" in "fileRegion0" in "rectInfoArray", the delimiter, and the area with "key" in "fileRegion1".

Then, in S517, the PC 140 uses the scan job acquired in S516 to display a file attribute setting screen for setting file attributes in a predetermined display area.
Here, an example of a process related to setting file attributes in response to an instruction from a user via a file attribute setting screen will be described with reference to Fig. 17. The series of processes shown in Fig. 17 are realized in the control unit 310 by the CPU 311 expanding and executing a control program stored in the HDD 314.

In S1701, the display control unit 435 of the MFP linkage service 120 generates initial file attributes (hereinafter also referred to as initial file attributes). The initial file attributes are generated based on the initial values of the file attributes acquired as result information at the time of completion of the target process in the process of S512. As a specific example, if the "value" of "formKeys" indicating the initial value is the value "scan", "scan" is added to the beginning of the initial file attributes. Also, in the result of the similar form determination acquired in S513, the value of "matched" is "true" and the "matchingScore" is a numerical value equal to or greater than a certain number (in this example, it is determined that similarity occurs when the value is 0.6 or greater). In this case, the initial file attributes are generated using the information of "rectInfoArray" in the order of "value" of "metadataArray".

In the example shown in FIG. 15, "metadataArray" is "fileRegion0", "separator", and "fileRegion1". Furthermore, in "rectInfoArray", "quotation" is stored as the value of "text" with "key" being "fileRegion0". Furthermore, "_" is stored as the value of "separator" in the result information acquired in S512. Furthermore, in "rectInfoArray", "Shimomaruko Co., Ltd." is stored as the value of "text" with "key" being "fileRegion0". Therefore, the character strings "quotation", "_", and "Shimomaruko Co., Ltd." are concatenated to generate an initial file attribute of "quotation_Shimomaruko Co., Ltd.".
If the value set as the initial value is "scan_", then the value "scan_quote_Shimomaruko Co., Ltd." with the characters indicated as the value added to the beginning becomes the value of the initial file attribute.
On the other hand, if the value of "matched" is "false" and the "matchingScore" is less than a certain number and there is no similar file, the initial value of the file attributes obtained at the completion of processing in S513 becomes the initial file attribute.

In S1702, the display control unit 435 executes processing related to displaying the file attribute setting screen based on the processing result in S1701.
11 is a diagram showing an example of a file attribute setting screen 1100 displayed via the PC 140. The file attribute setting screen 1100 includes a file attribute area 1101 and a preview area 1102.

The file attribute area 1101 is an area where file attributes such as the file name set in response to a user's specification are displayed. The preview area 1102 is an area where the scanned image is displayed. For example, in the initial state, the preview area 1102 displays an image corresponding to the first page of a series of scanned images.

In the example shown in FIG. 11, a character area in the scanned image displayed in the preview area 1102 can be selected by a touch operation or the like, and the selected character area can be added to the file attributes. At this time, a control for notifying the user that the target character area (or a character string corresponding to the character area) has been selected may be applied. As a specific example, the display mode such as the shape and color of the line or frame indicating the selected character area may be controlled to notify the user that the character area is the selection target. In addition, when multiple character areas are selected, a control for changing the display mode such as color and shape may be applied so that the user can distinguish between the respective areas. In addition, the above-mentioned control may be selectively switched whether to be applied or not depending on an instruction from the user via an interface such as a button. In addition, when an operation for changing the position of the target such as a swipe operation is performed on the preview area 1202, a control for changing the position of the image displayed in the preview area 1202 may be applied.

In addition, a send button 1103 is displayed in the file attribute area 1101. When the send button 1103 is pressed, the file attributes specified via the file attribute setting screen 1100 and the scanned image data for which the file attributes are to be set are sent to the MFP collaboration service 120.

In S1703, PC 140 waits for detection of an operation from the user. For example, when the user performs some operation such as a touch operation on the screen, the operation is detected. Note that, for the sake of convenience, in the example shown in FIG. 17, it is assumed that the user performs a touch operation on the screen to select a part of the screen. When this touch operation from the user is detected, PC 140 checks the area where the touch operation was performed in S1703, and determines what processing to execute in response to the operation.

Specifically, in S1704, the PC 140 determines whether the detected touch operation is an operation targeting a character area. This determination is made, for example, based on whether the coordinates of the position where the touch operation was performed are converted into coordinates indicating a position in the scanned image, and whether the converted coordinates are within the character area indicated in the result information acquired in S513.
If the PC 140 determines in S1704 that the touch operation detected is an operation directed to the character area, the PC 140 advances the process to S1706.
On the other hand, if the PC 140 determines in S1704 that the touch operation detected is not an operation targeting a character area, the PC 140 advances the process to S1705.

In S1706, the PC 140 adds information indicating characters corresponding to the selected character area to the file attribute, and updates the display of the file attribute area 1101 on the file attribute setting screen 1100 based on the file attribute to which the information has been added. The PC 140 also changes the display state to indicate that the character area has been selected, and records information indicating that the character area has been used in the file attribute. If information indicating characters corresponding to another character area has already been added to the file attribute, the PC 140 adds a delimiter and then adds information indicating characters corresponding to the selected character area. At this time, the PC 140 also records information indicating that a delimiter has been inserted, such as "character area 1", "delimiter", and "character area 2", as input information in the file attribute. As a specific example, the example shown in FIG. 11 shows a state after a character area indicating the characters "Shinagawa Limited Company" and a character area indicating the characters "R12-3456" are selected in the scanned image.
Then, after executing the process of S1706, the PC 140 advances the process to S1703. In this case, the processes from S1703 onwards are executed again.

In S1705, the PC 140 determines whether or not it has detected that the send button 1103 has been pressed.
If the PC 140 determines in S1705 that the send button 1103 has not been pressed, the process proceeds to S1703. In this case, the process from S1703 onwards is executed again.
On the other hand, if the PC 140 determines in S1705 that the send button 1103 has been pressed, the PC 140 ends the series of processes shown in Fig. 17. That is, in this case, the PC 140 advances the process to S518 shown in Fig. 5.

Here, the process from S518 onwards will be described with reference to FIG.
When the send button 1103 is pressed with the attribute values of the file attributes set for the scanned image data corresponding to the scan result of the target document on the file attribute setting screen 1100 shown in Fig. 11, the process of S518 is executed. In S518, the PC 140 transmits a form learning request including information indicating the character area specified when setting the file attributes (for example, the information shown in Fig. 12) to the MFP cooperation service 120.
When the request control unit 431 of the MFP cooperation service 120 accepts the request transmitted from the PC 140 in S518, the request control unit 431 requests the image processing unit 432 to perform form learning using the information included in the request as input in S519.
In S520, the image processing unit 432 saves information on the character regions in the entire target image and information on the character regions specified by the user as file attributes, which is included in the request accepted in S518.

In S<b>521 , the PC 140 transmits to the MFP cooperation service 120 the scanned image data and file attributes such as a file name that are set after the scanned image data is converted into a file.
When the MFP cooperation service 120 accepts the request sent from the PC 140 in S521, it starts processing related to file generation of the scanned image data in S522. The MFP cooperation service 120 also returns a response indicating that the request was accepted normally to the PC 140. When the PC 140 receives the response, it ends the series of processes on the PC 140 side shown in FIG.
In S522, the MFP collaboration service 120 acquires information on the file format to be sent to the cloud storage 130 from the previously registered scan settings. The MFP collaboration service 120 generates a file from the scanned image data in accordance with the acquired file format.
In S523, the MFP collaboration service 120 associates the information (attribute value) specified as the file attribute included in the request accepted in S521 with the file generated in S522, and then transmits the file to the cloud storage 130. Furthermore, upon completing transmission of the file to the cloud storage 130, the MFP collaboration service 120 saves a scan history. The scan history includes at least the "formId" of the target form, the user who instructed the scan, the transmission destination, and information on the confidence level.

As a result, a user can have the MFP 110 scan a document, set file attributes such as a file name to the scanned image data according to the scan results via the MFP collaboration service 120, and then store the data in cloud storage 130.

After the above-mentioned process has performed form learning based on the scan results of the target document, the learning content may be edited in response to instructions from the user. When editing the learning content, it is desirable to display an image of the target document (an image corresponding to the scan results) so that the user can visually understand the learning content. On the other hand, from the perspective of privacy, it may be undesirable for other users to freely view the image corresponding to the scan results. Therefore, an example of a process for selecting images that meet certain conditions from the scan history while taking privacy into consideration is described below.

In the above-mentioned process, the scanned image data of the document (form) on which form learning has been performed is uniquely assigned identification information, exemplified as "formId". The administrator user who is the main editor can edit the learning content linked to this "formId". Now, with reference to FIG. 19, an example of a process in which the MFP collaboration service 120 selects the target scanned image data file (i.e., the file used to display the scanned image) when the administrator user edits the learning content will be described. Note that in the example shown in FIG. 19, the administrator user who is the editor corresponds to an example of a "first user".

In S1901, the MFP collaboration service 120 checks the scan history linked to the target "formId". In the processing of S524 in FIG. 5, at least the "formId", the user who instructed the scan, the destination, and information on the confidence level are saved as the scan history. The MFP collaboration service 120 extracts a series of scan histories related to the target "formId", and executes processing according to the contents of the scan history in the processing from S1902 onwards, which will be described later.

In S1902, the MFP collaboration service 120 determines whether the series of scan histories acquired in S1901 includes a scan history in which information about an administrator user who is an editor is stored. Specifically, the MFP collaboration service 120 determines whether a scan history exists in which the administrator user matches the user who is the subject of the scan instruction indicated by the information stored in the scan history. In this case, the user who is the subject of the scan instruction indicated by the information stored in the scan history corresponds to an example of a "second user."
If the MFP cooperation service 120 determines in step S1902 that a scan history in which information about the administrative user is saved is included in the series of scan histories to be processed, the MFP cooperation service 120 advances the process to step S1903.
On the other hand, if the MFP cooperation service 120 determines in step S1902 that the series of scan histories does not include a scan history in which information about the administrator user is saved, the MFP cooperation service 120 advances the process to step S1906.

In S1903, the MFP cooperation service 120 determines, based on the scan history in which the administrative user information is stored, whether or not there are multiple images corresponding to the scan results based on the instruction from the administrative user.
If the MFP cooperation service 120 determines in S1903 that there are multiple image candidates corresponding to the scan results based on the instruction from the administrator user, the MFP cooperation service 120 advances the process to S1905.
On the other hand, if the MFP cooperation service 120 determines in S1903 that there are not multiple images corresponding to the scan results based on the instruction from the administrator user, the MFP cooperation service 120 advances the process to S1904.

The processing of S1904 is executed when there is one candidate image corresponding to the scan results based on instructions from the administrator user, as described above, in other words, when there is one candidate scan history in which the administrator user's information is saved. In this case, the MFP collaboration service 120 selects the target image (scanned image) as the image to be displayed. In other words, if the image is based on the results of a scan performed in response to instructions from the administrator user himself, there is no privacy issue, and so the MFP collaboration service 120 selects that image as the image to be displayed.

The process of S1905 is executed when there are multiple candidates for the image corresponding to the scan result based on the instruction from the administrator user, as described above, in other words, when there are multiple candidates in the scan history in which the administrator user information is saved. Therefore, in this case, the MFP collaboration service 120 selects an image with a higher degree of certainty in order to uniquely identify the target image. As described above, the degree of certainty is a numerical representation of the degree of match between the layout information of the image corresponding to the past scan result (the image of the document linked to the "formId") and the layout information of the image corresponding to the current scan result. In other words, the higher the degree of certainty, the more the image corresponds to the scan result of the document that matches the character string layout (in other words, the document format) of the target document (form). Therefore, in the example shown in FIG. 19, the MFP collaboration service 120 selects the image with a higher degree of certainty (for example, the image with the highest degree of certainty) as the image to be displayed.

The processing of S1906 is executed when the scan history linked to "formId" does not include a scan history in which information about the administrator user is saved, as described above. In this case, since it is difficult for the MFP collaboration service 120 to display an image of a document scanned in response to an instruction from the administrator user, the MFP collaboration service 120 determines an image that can be viewed by the administrator user from among images of documents scanned in response to an instruction from another user. Therefore, in S1906, the MFP collaboration service 120 checks the storage location of the file of the scanned image data corresponding to each scan history.

In S1907, the MFP cooperation service 120 determines whether or not there is a storage destination to which the administrator user, who is the editor, has access rights among the storage destination candidates confirmed in S1906. If the administrator user has access rights to the folder in which the file of the target document is stored, the administrator user has the authority to view the document, and therefore it is considered that there is no privacy problem even if the scanned image of the document is viewed.
If the MFP cooperation service 120 determines in step S1907 that a storage destination to which the administrator user has access rights exists, the process proceeds to step S1909.
On the other hand, if the MFP cooperation service 120 determines in step S1907 that there is no storage destination to which the administrator user has access rights, the process proceeds to step S1908.

As described above, the process of S1908 is executed when the administrator user does not have access rights to the storage destination of the scan history. In this case, the administrator user does not have the authority to view the file of the scanned image data saved in the storage destination, and therefore, from the viewpoint of privacy, it is undesirable to present the administrator user with a scanned image of the document corresponding to the scanned image data. Therefore, the MFP collaboration service 120 determines that it is not possible to display the scanned image of the target document. In this case, the MFP collaboration service 120 does not display the scanned image of the target document on the editing screen for editing the learning content, but instead displays the storage destination and file name of the file of the scanned image data of the document.

As described above, step S1909 is executed when the administrator user has the access right to the storage destination of the scan history. In this case, the MFP cooperation service 120 determines whether there are multiple candidates for the image whose file is saved in the storage destination to which the administrator user has the access right.
If the MFP cooperation service 120 determines in step S1909 that multiple candidates exist, the process proceeds to step S1911.
On the other hand, if the MFP cooperation service 120 determines in S1909 that there are not multiple candidates, the process proceeds to S1910.

The process of S1910 is executed when there is one candidate scanned image to which the administrator user has access rights, as described above. In this case, the MFP collaboration service 120 selects the target image (scanned image) as the image to be displayed.

As described above, the process of S1911 is executed when there are multiple candidate scanned images to which the administrator user has access rights. In this case, the MFP collaboration service 120 selects the image with the higher degree of certainty as the image to be displayed in order to uniquely identify the target image. Note that, as described above, the higher the degree of certainty, the more the image corresponds to the scanned document result that more closely matches the character string arrangement (in other words, the document format) of the target document (form).

By applying the above-mentioned control, it becomes possible to select an image based on the scan history that is more similar to the target document (form) in terms of text arrangement (in other words, document format) according to the scan results while respecting privacy. The selected image can also be presented to the user (e.g., administrator user) who will be the editor as a preview image by using, for example, an API or the like published in the cloud storage 130 where the image is stored.

Second Embodiment
A second embodiment of the present disclosure will be described below. In this embodiment, an example of a case where, when editing learning content in the first embodiment, a series of scan histories does not include a scan history in which information of an administrator user is saved, and processing is delegated to another administrator user will be described. Note that, in this embodiment, the description will focus on the parts that are different from the first embodiment, and detailed descriptions of parts that are substantially similar to the first embodiment will be omitted.

For example, in the process of S1908 shown in FIG. 19, if there are no images to which the administrator user has access rights, it is determined that the image cannot be displayed. In contrast, in this embodiment, if there are no images to which the administrator user has access rights, the process of editing the learning content corresponding to the scan history is delegated to another administrator user who can view the image (scanned image) indicated by the target scan history.

Figure 20 illustrates an example of processing in which, when there are no images to which the administrator user has access, the process of editing the learning content corresponding to the scan history is delegated to another administrator user who can view the images indicated by the target scan history.
In S2001, the MFP cooperation service 120 determines whether or not a series of scan histories to be processed includes a scan history in which information of an administrator user other than the editor user is stored.
If the MFP collaboration service 120 determines in S2001 that the scan history does not contain information about other administrative users, there is no user to which the processing can be transferred, and therefore the series of processing steps shown in FIG. 20 is terminated.
On the other hand, if the MFP cooperation service 120 determines in S2001 that the scan history includes information about another administrative user, the MFP cooperation service 120 advances the process to S2002.

In S2002, the MFP collaboration service 120 delegates the process of editing the learning content corresponding to the scan history to another administrator user whose information is included in the target scan history in S2001. The user to whom the process of editing the learning content has been delegated has access rights to the file of the scanned image data indicated by the target scan history, and is therefore able to view the image indicated by the scanned image data. Therefore, in this case, when the editing is performed by the user to whom the process of editing the learning content has been delegated (i.e., when the user is logged in), the MFP collaboration service 120 will display the image on the editing screen.

As described above, in the image processing system according to this embodiment, if there are no images that the administrator user can view when editing the learning content, the process of editing the learning content is delegated to another administrator user. With this mechanism, even if the administrator user does not have access rights to the image indicated by the target scan history, the work related to editing the learning content can be continued by transferring the access rights to the image to another administrator user who has access rights to the image.
