In the system according to the present embodiment, the MFP 110 is used as a client terminal that displays and operates an operation screen of a Web application using a Web browser. Further, the MFP 110 can print an image acquired from the Web application using the printer unit 113 or send an image scanned using the scanner unit 112 to the Web application according to an instruction from the Web application. In the present embodiment, an identifier called a device ID is assigned to the MFP 110, and an individual can be uniquely identified.

  The web application server 120 is a server that executes a web application. Note that the number of these component devices is an example, and other devices may be included, or a plurality of devices may be included.

[Hardware configuration]
FIG. 2 shows an example of the hardware configuration of the MFP 110 shown in FIG. The operation unit 111 includes a touch panel display and the like, and has a function of displaying information to the user and receiving input from the user. The scanner unit 112 performs an operation of reading an image on a document placed at a predetermined position, and creates image data. The printer unit 113 forms the image data received from the controller unit 200 as a print image on a recording medium such as paper.

  The controller unit 200 is electrically connected to the operation unit 111, the scanner unit 112, and the printer unit 113, and is also connected to the LAN 100 via the network I / F 206. As a result, the MFP 110 can communicate using a communication protocol such as TCP / IP.

The Web content drawing unit 303 calls the WebView 304 as necessary, and executes Web content drawing processing. A WebView 304 is a UI component that displays Web content. The WebView 304 transmits a request to the Web application server 120 using HTTP (HyperText Transfer Protocol). Then, the WebView 304 renders an HTML (Hyper Text Markup Language) document received as the response and displays it on the operation unit 111. When the Web content setting information is changed, the WebView 304 transmits event information including the changed setting information.

  The initial value determination unit 305 is a software module that determines whether or not Web content setting information is different from that at the time of initial display. The setting information event receiving unit 306 is a software module that receives event information transmitted from the WebView 304. The Web content presence determination unit 307 is a software module that determines whether the GUI application 301 displays Web content. The setting information changing unit 308 is a software module that provides setting information changing means to the user. The setting information control unit 309 is a software module that stores and updates setting information. The condition determination unit 310 is a software module that determines whether to store stored information.

  The MFP 110 also includes a setting information management table 311 and a storage condition table 312 that are used by the Web content drawing application 302. These tables are held in the HDD 204, for example.

  The setting information management table 311 is a database table for storing Web content setting information for each user, GUI application 301, and Web content. Table 1 shows a configuration example of information recorded in the setting information management table 311 of the database.

  The user ID indicates an ID (identifier) for uniquely identifying the user who operates the Web content. The application ID indicates an ID (identifier) for uniquely identifying the GUI application 301 that displays Web content. The Web content URL indicates the URL (Uniform Resource Locator) of the Web content to be displayed. The setting information indicates binary data of setting information of the Web content to be stored. In addition, about setting information, the information contained may differ according to the content of Web content.

  The storage condition table 312 is a database table in which conditions for storing Web content setting information are recorded. Table 2 shows a configuration example of information recorded in the storage condition table 312 of the database.

  The user ID indicates an ID for uniquely identifying an operating user as a condition for storing Web content setting information. The application ID indicates an ID for uniquely identifying the GUI application 301 displaying the Web content as a condition for storing the Web content setting information. The web content URL indicates the URL of the web content for which setting information is stored, and the web content is specified by this URL.

  In the present embodiment, the administrator of the MFP 110 registers each record (condition) in the storage condition table 312 in advance. In the present embodiment, the case where the user ID, the application ID, and the URL of the Web content all match is set as a recording condition. However, the present invention is not limited to this. For example, the setting information may be stored when the combination of the user ID and the application ID matches.

[Screen configuration of GUI application]
FIG. 4 shows an example of the screen configuration of the GUI application 301 displayed on the operation unit 111. A display area 401 is a display unit of the GUI application 301. A display area 402 is a display unit for Web content drawn by the Web content drawing application 302. That is, a part of the screen of the GUI application 301 is configured as a Web content display unit.

  A part 403 is a GUI component for the user to change setting information in the display area 401 of the GUI application 301 excluding the display area 402 of the Web content. A part 404 is a GUI component for the user to change the setting information of the display area 402 of the Web content. In the present specification, for convenience, the part 404 is also referred to as a first receiving unit, and the part 403 is also referred to as a second receiving unit.

[Processing flow]
The setting information storage process related to the display according to the present embodiment will be described below. In addition, although the example of four processes is shown below, these are not exclusive, respectively, and suppose that it can process combining the characteristic as needed.

(Setting information storage processing when initial value judgment is performed)
A process for storing Web content setting information in the case where initial value determination is performed according to the present embodiment will be described. FIG. 5 is a flowchart showing a storage process of Web content setting information when initial value determination is performed. This processing flow is realized by the CPU 201 of the MFP 110 reading and executing various programs stored in the HDD 204 or the like.

  In S501, the MFP 110 transitions to a login state by a user login operation. The login operation here is executed by performing a general authentication process using, for example, a user ID and a password, but is not particularly limited.

  In step S <b> 502, the GUI application 301 calls the web content drawing application 302, and the web content drawing application 302 calls the web content drawing unit 303. Further, the web content drawing unit 303 calls the web view 304 and acquires the initial value of the web content setting information.

  In step S <b> 503, the Web content drawing application 302 calls the setting information control unit 309 and searches the setting information management table 311. The setting information control unit 309 searches the setting information management table 311 for a record that matches the user ID of the logged-in operating user, the application ID of the GUI application 301, and the URL of the Web content. As a result of the search, if it is detected that a matching record exists (YES in S503), the process proceeds to S504. If there is no matching record (NO in S503), the process proceeds to S505.

  In step S504, the Web content drawing application 302 calls the Web content drawing unit 303, and the Web content drawing unit 303 calls the WebView 304. The WebView 304 uses the setting information acquired from the records that existed in the setting information management table 311 to render Web content. Thereafter, the process proceeds to S506.

  In step S <b> 505, the web content drawing application 302 calls the web content drawing unit 303, and further the web content drawing unit 303 calls WebView 304. WebView 304 renders Web content. At this time, unlike the processing in S504, the WebView 304 renders the Web content with the initial value of the setting information acquired in S502.

  In step S506, the setting information change unit 308 receives a change in setting information from the user. Note that the setting information here is not necessarily changed, and is accepted only when there is a user operation.

  In S507, the MFP 110 transitions to a logout state by a user logout operation. The logout operation is performed, for example, when the user presses a logout button (not shown) on the screen, thereby executing logout processing, but is not particularly limited.

  In step S <b> 508, the web content drawing application 302 calls the web content drawing unit 303, and the web content drawing unit 303 calls the web view 304 to obtain the latest web content setting information. The latest Web content setting information here corresponds to the setting information changed by the user in S506. The Web content drawing application 302 calls the initial value determination unit 305 and compares the initial value of the Web content setting information acquired in S502 with the latest Web content setting information. If the setting information is different as a result of the comparison (YES in S508), the process proceeds to S508. If the setting information is the same (NO in S508), the process flow ends.

  In step S509, the Web content drawing application 302 calls the setting information control unit 309. The setting information control unit 309 registers the latest Web content setting information in the setting information management table 311 with the user ID, the application ID of the GUI application 301, and the Web content URL as keys. If a record with the same key already exists in the setting information management table 311, the setting information control unit 309 updates the setting information of the corresponding record by overwriting. Thereafter, this processing flow ends.

(Storage processing of setting information when determining storage conditions)
A storage process of Web content setting information when determining storage conditions according to the present embodiment will be described. FIG. 6 is a flowchart showing a storage process of Web content setting information when the storage condition is determined. This processing flow is realized by the CPU 201 of the MFP 110 reading and executing various programs stored in the HDD 204 or the like.

  In step S601, the MFP 110 transitions to a login state by a user login operation. The login operation is assumed to be the same as S501 in FIG.

  In step S <b> 602, the GUI application 301 calls the web content drawing application 302, and the web content drawing application 302 calls the setting information control unit 309. The setting information control unit 309 searches the setting information management table 311. The setting information control unit 309 searches the setting information management table 311 for a record that matches the user ID of the logged-in operating user, the application ID of the GUI application 301, and the URL of the Web content. If there is a matching record (YES in S602), the process proceeds to S603. If there is no matching record (NO in S602), the process proceeds to S604.

  In step S <b> 603, the web content drawing application 302 calls the web content drawing unit 303, and the web content drawing unit 303 calls the WebView 304. The WebView 304 uses the setting information acquired from the records that existed in the setting information management table 311 to render Web content. Thereafter, the process proceeds to S605.

  In step S <b> 604, the web content drawing application 302 calls the web content drawing unit 303, and the web content drawing unit 303 calls the WebView 304. WebView 304 renders Web content. At this time, unlike the processing of S603, the WebView 304 renders the Web content with the initial value of the Web content.

  In step S605, the setting information change unit 308 receives a change in setting information from the user. Here, the setting information is not necessarily changed, but is accepted when a user operation is performed.

  In S606, MFP 110 transitions to a logout state by a user logout operation. The logout operation is the same as S507 in FIG.

  In step S <b> 607, the web content drawing application 302 calls the condition determination unit 310. The condition determination unit 310 searches the storage condition table 312 for a record that matches the user ID of the operating user who performed the logout operation in S606, the application ID of the GUI application 301, and the URL of the Web content. If there is a matching record (YES in S607), the process proceeds to S607. If there is no matching record (NO in S607), the process flow ends.

  In step S <b> 608, the web content drawing application 302 calls the web content drawing unit 303, and the web content drawing unit 303 calls the WebView 304. The WebView 304 acquires the latest Web content setting information. The latest Web content setting information here corresponds to the setting information changed by the user in S605. Further, the Web content drawing application 302 calls the setting information control unit 309. The setting information control unit 309 registers the latest Web content setting information in the setting information management table 311 using the user ID, the application ID of the GUI application 301, and the URL of the Web content as keys. If a record with the same key already exists, the setting information control unit 309 overwrites and updates the setting information of the corresponding record. Thereafter, this processing flow ends.

(Storing processing of setting information when storing when changing setting information)
A process for storing Web content setting information when storing the setting information when the setting information is changed will be described. FIG. 7 is a flowchart showing the storage processing of the Web content setting information when it is stored when the setting information is changed. This processing flow is realized by the CPU 201 of the MFP 110 reading and executing various programs stored in the HDD 204 or the like.

  In step S <b> 701, the web content drawing application 302 sets the event information transmitted from the web view 304 so that the setting information event reception unit 306 receives the event information. The setting process here can be performed, for example, by registering a listener for receiving event occurrence. Since S702 to S705 are the same processes as S601 to S604, respectively, description thereof will be omitted. After the process of S704 or S705, the process proceeds to S706.

  In step S <b> 706, the setting information change unit 308 determines whether a change in Web content setting information has been received from the operation user. If the setting information has been changed (YES in S706), WebView 304 transmits event information indicating that the setting information of the Web content has been changed to setting information event reception unit 306. The setting information event receiving unit 306 receives event information transmitted from the WebView 304. If the Web content setting information has been changed (YES in S706), the process proceeds to S707. If the Web content setting information has not been changed (NO in S706), the process flow ends.

  In S707, the setting information event reception unit 306 calls the setting information control unit 309. The setting information control unit 309 uses the user ID of the logged-in operation user, the application ID of the GUI application 301, and the URL of the Web content as keys, and the changed Web content included in the event information transmitted from the WebView 304 Are registered in the setting information management table 311. If a record with the same key already exists, the setting information control unit 309 updates the setting information of the corresponding record. Thereafter, this processing flow ends.

(Setting information storage processing when setting information is inherited)
A process for storing setting information of Web content when the setting information is transferred from the GUI application 301 (parent) to the Web content (child) according to the present embodiment will be described. As a premise, the GUI application 301 is defined as a parent, and Web content to be rendered in the display area (specifically, the display area 401 in FIG. 4) of the GUI application 301 is defined as a child.

  FIG. 8 is a flowchart showing the storage processing of the web content setting information when the GUI application 301 takes over the setting information from the GUI content. This processing flow is realized by the CPU 201 of the MFP 110 reading and executing various programs stored in the HDD 204 or the like.

  In step S801, the MFP 110 transitions to a login state by a user login operation. The login operation is assumed to be the same as S501 in FIG.

  In step S <b> 802, the GUI application 301 calls the web content drawing application 302. When calling, setting information of the GUI application 301 is passed to the Web content drawing application 302. The web content drawing application 302 calls the web content presence determination unit 307, and the web content presence determination unit 307 determines whether the web content is displayed in the display area of the GUI application 301. If Web content is being displayed (YES in S802), the process proceeds to S803. If the Web content is not displayed (NO in S802), the process proceeds to S804.

  In step S803, the web content drawing application 302 calls the web content drawing unit 303, and the web content drawing unit 303 calls the web view 304. The WebView 304 renders the Web content using the setting information of the GUI application 301 acquired by the Web content rendering application 302 in S802. Then, the process proceeds to S804. At this time, settings that are not specified in the setting information of the GUI application 301 may be displayed using the initial value of the Web content.

  In step S804, the setting information changing unit 308 receives a setting information change from the user. Here, the setting information is not necessarily changed, but is accepted when a user operation is performed. The setting change here is not limited to the setting change using the part 404 for the display area 402 for displaying the Web content shown in FIG. That is, the change of the setting information here may reflect the setting change using the part 403 for the display area 401 of the screen of the GUI application 301.

  In step S805, the MFP 110 transitions to a logout state by a user logout operation. The logout operation is the same as S507 in FIG.

  In step S806, the web content drawing application 302 calls the web content drawing unit 303, and the web content drawing unit 303 calls the web view 304 to acquire the latest web content setting information. Here, the latest Web content setting information corresponds to the setting information changed by the user in S804. Further, the Web content drawing application 302 calls the setting information control unit 309. The setting information control unit 309 registers the latest Web content setting information in the setting information management table 311 using the user ID that performed the logout operation in S805, the application ID of the GUI application 301, and the URL of the Web content as keys. To do. If a record with the same key already exists, the setting information control unit 309 updates the setting information of the corresponding record. Thereafter, this processing flow ends.

  In the processing flow shown in FIG. 8, the configuration information is uniformly inherited for the Web content displayed on a part of the screen of the GUI application 301. However, the present invention is not limited to this. For example, a GUI application provided in the MFP and a predetermined Web content are defined in association with each other as a parent-child relationship. Then, only when the defined parent-child relationship is established at the time of rendering the Web content, the setting information for displaying the screen of the parent GUI application is inherited as the setting information for rendering the Web content that is the child. Also good.

  According to the present embodiment, by providing conditions regarding the type and state of the Web content, it is possible to store only necessary Web content setting information that matches the conditions. As a result, even in an information processing apparatus such as an MFP that is assumed to have a limited storage area capacity, consumption of the storage area can be suppressed.
