However, in the present embodiment, the information processing terminal 20 may not have the wireless communication device 205.

  FIG. 4 is a diagram illustrating a functional configuration example of each apparatus according to the first embodiment. In FIG. 4, the information processing terminal 20 includes an authentication UI unit 21, an input support unit 22, a determination unit 23, an image output unit 24, an operation control unit 25, and the like. Each of these units is realized by processing that one or more programs installed in the information processing terminal 20 cause the CPU 201 to execute. The information processing terminal 20 also uses the image storage unit 26.

  The image storage unit 26 stores image data that is display content on the display device 211. In other words, the content drawn on the image storage unit 26 is displayed on the display device 211. For example, a VRAM may be used as the image storage unit 26. The VRAM may be realized using, for example, the memory 202 or may be realized using a dedicated memory different from the memory 202.

  In order to authenticate the operator (user) of the image forming apparatus 10 in a state where the image forming apparatus 10 is not logged in, the authentication UI unit 21 identifies information (hereinafter referred to as “personal”, such as a user ID and a password). A login screen for accepting input of “specific information” is displayed on the display device 211. Authentication is performed for the purpose of document management and protection of confidential information, for example. The login screen is displayed by drawing an image indicating the login screen in the image storage unit 26.

  FIG. 5 is a diagram illustrating a display example of a login screen. As shown in FIG. 5, the login screen 510 has a user ID and password input area.

  The input support unit 22 supports character input on various screens. For example, when any input area is touched on the login screen 510 and the start of character input is instructed, the input support unit 22 draws the virtual keyboard in the image storage unit 26. As a result, the virtual keyboard is displayed on the display device 211.

  FIG. 6 is a diagram illustrating a display example of the virtual keyboard. FIG. 6 shows an example in which a virtual keyboard 520 is displayed superimposed on the lower side of the login screen 510. The virtual keyboard 520 is a screen on which a list of keys corresponding to characters (symbols) as input candidates is arranged.

  When the user selects any key on the virtual keyboard 520, the input support unit 22 changes (for example, highlights) the display mode of the selected key, and also displays a character corresponding to the selected key. , Reflect (transcribe) the input area to be operated. At this time, if the input area is an input area corresponding to highly confidential information such as a password, the input support unit 22 selects a character selected to prevent erroneous input for a certain period immediately after the input. Although it is displayed as it is, the character is masked by replacing the character with a symbol such as “●” or “*” after a certain period of time to prevent peeping from others.

  FIG. 7 is a diagram illustrating a state where an input character is masked. FIG. 7 shows an example in which the password input area of the login screen 510 is an operation target. In the input area, a character that has passed for a fixed time after being input is replaced with “●”, and a character before the fixed time has passed (“M” in FIG. 7) is displayed as it is.

  The input support unit 22 deletes the virtual keyboard 520 from the image storage unit 26 when the input of the character string is completed. As a result, the virtual keyboard 520 is hidden.

  The determination unit 23 determines whether or not the virtual keyboard 520 is displayed on the display device 211.

  In response to a request from the external device 30, the image output unit 24 outputs (transmits) the image data (whether a still image or a moving image) stored in the image storage unit 26 to the external device 30 via the network. . That is, the image output unit 24 outputs a captured image of the content displayed on the display device 211 to the external device 30.

  The operation control unit 25 causes the image forming apparatus 10 to execute processing corresponding to an operation (that is, remote operation) performed on the screen related to the captured image output to the external device 30.

  The controller 11 includes a web page management unit 121, an authentication unit 122, and the like. Each of these units is realized by processing that one or more programs installed in the controller 11 cause the CPU 111 to execute.

  The web page management unit 121 manages web pages that can be provided by the image forming apparatus 10. The authentication unit 122 executes user authentication processing of the image forming apparatus 10.

  On the other hand, the external device 30 includes an image output request unit 31, an output image display unit 32, and the like. Each of these units is realized by a process in which one or more programs installed in the external device 30 are executed by the CPU of the external device 30.

  The image output request unit 31 transmits an output request for image data (that is, a captured image) indicating the display content of the display device 211 to the image forming apparatus 10, and receives the image data from the image forming apparatus 10.

  The output image display unit 32 displays the image data received by the image output request unit 31 on the display device of the external device 30. In the present embodiment, the image forming apparatus 10 has a Web server function, and the image output request unit 31 and the output image display unit 32 are realized by a Web browser (hereinafter simply referred to as “browser”) of the external device 30. Although an example will be described, the image output request unit 31 and the output image display unit 32 may be implemented as a dedicated application program.

  Hereinafter, a processing procedure executed in the information processing system 1 will be described. FIG. 8 is a sequence diagram for explaining an example of a processing procedure executed by the information processing system according to the first embodiment.

  In step S110, when the user operating the external device 30 instructs to start the browser, the image output request unit 31 displays a browser screen (hereinafter referred to as “browser screen”).

  Subsequently, address information (for example, URL (Uniform Resource Locator) for a Web page on which a user displays a captured image display screen (hereinafter referred to as “display screen”) including the IP address of the image forming apparatus 10. )) Is input to the browser screen (S120), the image output request unit 31 transmits an acquisition request for the Web page to the image forming apparatus 10 associated with the IP address (S130). The acquisition request is received by the Web page management unit 121 of the controller 11 of the image forming apparatus 10. Since the Web page has an authentication function, the Web page management unit 121 returns a response including an input request for personal identification information (S140). In response to the response, the image output request unit 31 displays a screen for inputting personal identification information.

  When the personal identification information is input by the user (S150), the image output request unit 31 transmits an authentication request for the personal identification information to the web page management unit 121 of the controller 11 (S160). The web page management unit 121 requests the authentication unit 122 to perform authentication processing of the personal identification information. The authentication unit 122 performs an authentication process on the personal identification information and returns an authentication result to the Web page management unit 121. If the authentication is successful, the Web page management unit 121 returns a Web page that displays a display screen (S170). If authentication fails, the Web page is not returned.

  When receiving the Web page, the image output request unit 31 displays a display screen based on the Web page. The display screen is a screen including a button for receiving a capture image acquisition instruction, a capture image display area, and the like.

  When a capture image acquisition instruction is input by the user of the external device 30 via the display screen (S180), the image output request unit 31 sends a capture image acquisition request to the Web page that is the response source of the Web page. It transmits to the management part 121 (S190). The web page management unit 121 transmits the acquisition request to the information processing terminal 20 connected to the controller 11 (S200).

  In response to the acquisition request, the determination unit 23 determines whether the virtual keyboard 520 is currently displayed on the display device 211 (S210). The determination of whether or not the virtual keyboard 520 is displayed may be performed by checking whether an application program process that displays the virtual keyboard 520 is activated at that time, or by an inquiry to the input support unit 22. May be. Alternatively, it may be performed based on a notification of display or non-display of the virtual keyboard 520 from the input support unit 22. In this case, the input support unit 22 notifies the determination unit 23 that the virtual keyboard 520 is displayed when the virtual keyboard 520 is displayed, and the virtual keyboard 520 is not displayed when the virtual keyboard 520 is hidden. What is necessary is just to notify the determination part 23. In addition, the determination unit 23 refers to the image data stored in the image storage unit 26 and determines whether or not the virtual keyboard 520 is present based on whether or not the image data includes an image indicating the virtual keyboard. Also good.

  When the determination unit 23 determines that the virtual keyboard 520 is displayed, that is, the virtual keyboard 520 is being displayed, the image output unit 24 determines that the captured image cannot be transmitted, and an error message ( For example, if “current screen cannot be acquired” is included, dummy image data is transmitted (output) to the Web page management unit 121 (S220).

  On the other hand, when the determination unit 23 determines that the virtual keyboard 520 is not displayed, that is, the virtual keyboard 520 is not displayed, the image output unit 24 stores the image data stored in the image storage unit 26 (that is, , The captured image) is transmitted (output) to the Web page management unit 121 (S230). Note that the captured image may be a still image or a moving image.

  Subsequently, the Web page management unit 121 transmits the image data transmitted from the image output unit 24 to the external device 30 that is the transmission source of the capture image acquisition request (S240). The output image display unit 32 of the external device 30 displays the image data on the display screen. Accordingly, dummy image data is displayed if the virtual keyboard 520 is displayed on the information processing terminal 20, and a captured image is displayed if the virtual keyboard 520 is not displayed on the information processing terminal 20. In this case, the user of the external device 30 can view the captured image or save it in the external device 30.

  Further, the user of the external device 30 can remotely operate the screen related to the captured image. For example, when the user operates a component such as a button or icon on the screen, the output image display unit 32 transmits an operation event for the component to the information processing terminal 20. The operation control unit 25 of the information processing terminal 20 causes the information processing terminal 20 to execute processing according to the operation event.

  On the other hand, even when dummy image data is transmitted to the external device 30, that is, during the period when the virtual keyboard 520 is displayed, even if an operation event for the screen related to the dummy image data is received by the information processing terminal 20. The operation control unit 25 ignores the operation event. That is, the process corresponding to the operation event is not executed.

  As described above, according to the first embodiment, during the period in which the virtual keyboard 520 is displayed on the information processing terminal 20 (that is, while characters are being input), the captured image of the display content on the information processing terminal 20 is It is not output externally. When highly confidential security information such as a password is input, the virtual keyboard 520 is likely to be displayed. Therefore, according to the first embodiment, it is possible to prevent a decrease in security due to an image being displayed being output to the outside.

  In the present embodiment, whether or not a captured image can be output is determined regardless of whether or not the character string being input using the virtual keyboard 520 includes security information. Therefore, each application program that provides a screen to which a character string input using the virtual keyboard 520 is input needs to register whether each input item on the screen is an item to which security information is input. It can be easily realized.

  Next, a second embodiment will be described. In the second embodiment, differences from the first embodiment will be described. Therefore, points not particularly mentioned may be the same as those in the first embodiment.

  In the second embodiment, when the identification information (personal identification information) of the user who operates the image forming apparatus 10 matches the identification information (personal identification information) of the user who operates the external apparatus 30, the external apparatus Output of the captured image to 30 is permitted.

  FIG. 9 is a diagram illustrating a functional configuration example of each device according to the second embodiment. 9, parts that are the same as the parts shown in FIG. 4 are given the same reference numerals, and explanation thereof is omitted. As illustrated in FIG. 9, the information processing terminal 20 may not have the determination unit 23. On the other hand, the Web page management unit 121 included in the controller 11 inquires of the authentication unit 122 whether or not the user of the image forming apparatus 10 and the user of the external apparatus 30 are the same.

  FIG. 10 is a sequence diagram for explaining an example of a processing procedure executed by the information processing system according to the second embodiment. 10, the same steps as those in FIG. 8 are denoted by the same step numbers, and the description thereof is omitted as appropriate.

  In step S 101, a user who directly operates the image forming apparatus 10 (hereinafter referred to as “local user”) performs a login operation via the information processing terminal 20. For example, the local user inputs personal identification information on the login screen displayed by the authentication UI unit 21 on the display device 211 of the information processing terminal 20.

  Subsequently, the authentication UI unit 21 requests the authentication unit 122 of the controller 11 to perform authentication processing of the input personal identification information (S102). The authentication unit 122 executes an authentication process on the personal identification information, and returns a result of the authentication process to the authentication UI unit 21 (S103). If the authentication is successful, the authentication unit 122 stores the personal identification information in the RAM 112, for example, as identification information of the local login user to the image forming apparatus 10. That is, the identification information of the local login user is specified by the authentication unit 122. When the response from the authentication unit 122 indicates that the authentication is successful, the authentication UI unit 21 deletes the login screen and enables the image forming apparatus 10 to operate (S104). Thereafter, the local login user operates the image forming apparatus 10 via the information processing terminal 20 (S105-1 to S105-n). For example, any application program installed in the image forming apparatus 10 may be used.

  Subsequently, steps S110 to S190 are executed in response to an operation of the external device 30 by a user of the external device 30 (hereinafter referred to as “external user”). In the authentication process in response to the authentication request in step S160, when the authentication is successful, the authentication unit 122 stores the personal identification information of the external user as the identification information of the external login user, for example, in the RAM 112. That is, the identification information of the external login user is specified by the authentication unit 122.

  In response to the capture image acquisition request transmitted from the external device 30 in step S190, the web page management unit 121 inquires of the authentication unit 122 whether the external login user and the local login user are the same. In response to the inquiry, the authentication unit 122 compares the identification information (individual identification information) of the external login user with the identification information (individual identification information) of the local login user, and returns a comparison result to the web page management unit 121. (S191). The comparison result is information indicating whether or not the compared identification information is the same.

  If the comparison results indicate the same, steps S200, S230, and S240 are executed, and the captured image is output (transmitted) to the external device 30.

  On the other hand, when the comparison results indicate that they are not the same, the Web page management unit 121 outputs (transmits) dummy image data to the external device 30 (S250).

  In the second embodiment as well, even if an operation event for a screen related to dummy image data is received by the information processing terminal 20, the operation control unit 25 ignores the operation event.

  As described above, according to the second embodiment, the captured image is output to the external device 30 only when the user identification information of the image forming apparatus 10 matches the user identification information of the external device 30. Is done. Therefore, according to the second embodiment, it is possible to prevent a decrease in security due to an image being displayed being output to the outside.

  Note that the case where the identification information of the user of the image forming apparatus 10 and the identification information of the user of the external apparatus 30 match is in addition to the case where the user of the image forming apparatus 10 and the user of the external apparatus 30 are the same person. This also includes cases where the persons share account information (personal identification information). For example, when account information of the group is shared by a plurality of persons belonging to the same group for business purposes, the account information of the user A belonging to the group at the time of logging in to the image forming apparatus 10 from the information processing terminal 20 When the user B belonging to the group inputs the account information when logging in from the external device 30, the user identification information compared in step S191 matches. Therefore, even in such a case, output of the captured image to the external device 30 is permitted. The operation performed when logging in with the account information of the group is an operation performed within the scope of the authority of the group, and information displayed on the display device 211 of the information processing terminal 20 in response to such operation is This is because there is a high possibility that sharing by the members of the group is permitted.
