This completes the description of the various processing functions that make up the controller unit 12.

  Next, the operation of the image processing system shown in FIG. 1 will be described with reference to FIG. Here, the flow of operations when accessing the Web server B using the Web browser 10a on the copying machine 10 will be described. In addition, when accessing the Web server A and the internal server 61, the operation described in FIG.

  In this process, first, the access destination is designated by the user. The designation of the access destination is performed by a method of directly inputting an access destination address, a method of selecting from a pre-registered access destination list, or the like.

  Here, when an access destination is specified (step S101) and an instruction to start access to the access destination is issued (step S102), the web browser function unit 62 that has received this instruction accesses the access destination. Prior to this, first, the screen transition prohibition necessity determination unit 48 determines whether to prohibit screen transition based on an operation from the menu bar. This determination is made based on the browser setting information held in the setting information holding unit 42 (step S103).

  As a result of the determination, when the screen transition based on the operation from the menu bar is not prohibited (NO in step S104), the web browser function unit 62 displays a web browser screen having a normal menu bar configuration in the display processing unit 45. While being displayed on the display unit 11b (step S105), the Web content acquisition unit 43 acquires Web content from the Web server B that is the access destination. That is, a request is transmitted to the Web server B (Step S106), and a response from the Web server B to the request is received.

  When a response to the request is sent, the Web browser function unit 62 receives the response at the Web content acquisition unit 43 and displays a progress bar and an hourglass indicating the progress status at the display processing unit 45. (Step S107). Then, the web page rendering processing unit 44 renders a web page based on the response, and the display processing unit 45 displays the rendered web page in the web page display area of the web browser screen (step S108). . Note that the display mode of the Web browser screen from step S105 to step S108 is as shown in FIG.

  Further, as a result of the determination in step S103, when the screen transition based on the operation from the menu bar is prohibited (YES in step S104), the web browser function unit 62 hides the menu bar in the display processing unit 45. The Web browser screen thus displayed is displayed on the display unit 11b (step S109), and the Web content acquisition unit 43 acquires Web content from the Web server B that is the access destination. That is, a request is transmitted to the web server B (step S110), and a response from the web server B to the request is received.

  When a response to the request is sent, the web browser function unit 62 receives the response at the web content acquisition unit 43 (step S111). At this time, the progress bar and hourglass indicating the progress of the response are not displayed. Then, the web page rendering processing unit 44 renders a web page based on the response, and the display processing unit 45 displays the rendered web page in the web page display area of the web browser screen (step S112). . The display mode of the web browser screen from step S109 to step S112 is as shown in FIG. In this case, since the menu bar, progress bar, and hourglass are not displayed, it is not necessary for the user to be aware that the user is accessing the outside of the copier 10, and the user is given the illusion of operating the device UI. It is done.

  Further, when the Web server is provided in the inside, that is, for example, the Web content for setting the processing conditions of the copying machine itself stored in the internal server 61 is displayed, and the operation setting based on the display content In this case, it is not necessary for the user to recognize that the user is operating the web browser, and it is rather unnecessary for the user to perform the setting operation while feeling that the user is operating the normal device UI. You don't have to give it. For this reason, it is preferable not to display a menu bar, a progress bar, an hourglass, or the like in a case where an operation screen for processing condition input stored in the internal server is displayed.

  Further, when the screen for performing the setting operation of the device stored in the internal server 61 is displayed, the setting that has been displayed inadvertently while the processing condition setting operation is being performed. If the screen transition that allows you to return to the screen is allowed, inconsistencies may occur between the settings that have been made so far and the settings that were previously displayed on the settings screen, or the effectiveness of the settings may be unclear. Thus, there is a possibility that a process unexpected by the copying machine is executed and a malfunction occurs. Also from this point of view, when displaying the content stored in the internal server, particularly the operation screen for setting the device, the control for prohibiting the screen transition is effective.

  The above is the description of the first embodiment. In the first embodiment, when the menu display is off, the display of the menu bar is not displayed and the display of the progress bar and the hourglass is also not displayed. When is off, only the menu bar may be hidden.

  The progress bar and hourglass described in the first embodiment are an example of a display that makes the user aware of access to the outside of the copying machine 10, and external access is provided to the user even in other displays. The display that makes you conscious is the same as the progress bar and hourglass. For example, a display indicating that the network is being accessed is a non-display target, similar to the progress bar and hourglass.

  Further, in the first embodiment, the case has been described in which the screen transition based on the operation from the menu bar is prohibited by controlling the display of the menu bar to be non-displayed in the non-display processing unit 49a. In 49b, screen transition based on the operation from the menu bar may be prohibited by invalidating the operation from the menu bar.

  Next, Example 2 will be described. In the second embodiment, an operation when a part of the function (button, display area, etc.) of the menu bar on the Web browser screen is hidden will be described. Here, as an example of the case where some functions of the menu bar are hidden, an operation when only the back button and the forward button are hidden and the screen transition based on the operation from the menu bar is prohibited will be described. Note that the overall configuration of the second embodiment and the configuration of the copying machine 10 are substantially the same as those of FIGS.

  Here, the operation of the image processing system according to the second embodiment will be described with reference to FIG. Here, the flow of operations when accessing the Web server B using the Web browser 10a on the copying machine 10 will be described. Note that when accessing the Web server A and the internal server 61, the operation described in FIG.

  In this process, first, the access destination is designated by the user. The designation of the access destination is performed by a method of directly inputting an access destination address, a method of selecting from a pre-registered access destination list, or the like.

  Here, when an access destination is specified (step S201) and an instruction to start access to the access destination is given (step S202), the web browser function unit 62 that has received this instruction accesses the access destination. Prior to this, first, the screen transition prohibition necessity determination unit 48 determines whether to prohibit screen transition based on an operation from the menu bar. This determination is made based on the browser setting information held in the setting information holding unit 42 (step S203).

  As a result of the determination, when the screen transition based on the operation from the menu bar is not prohibited (NO in step S204), the web browser function unit 62 displays a web browser screen having a normal menu bar configuration in the display processing unit 45. While being displayed on the display unit 11b (Step S205), the Web content acquisition unit 43 acquires Web content from the Web server B that is the access destination. That is, a request is transmitted to the Web server B (step S206), and a response from the Web server B to the request is received.

  When a response to the request is sent, the web browser function unit 62 receives the response at the web content acquisition unit 43 (step S207). Then, the web page rendering processing unit 44 renders a web page based on the response, and the display processing unit 45 displays the rendered web page in the web page display area of the web browser screen (step S208).

  Further, as a result of the determination in step S203, when the screen transition based on the operation from the menu bar is prohibited (YES in step S204), the web browser function unit 62 uses the return button and the forward button in the display processing unit 45. The hidden web browser screen is displayed on the display unit 11b (step S209), and the web content acquisition unit 43 acquires the web content from the web server B that is the access destination. That is, a request is transmitted to the Web server B (step S210), and a response from the Web server B to the request is received.

  When a response to the request is sent, the web browser function unit 62 receives the response at the web content acquisition unit 43 (step S211). Then, the web page rendering processing unit 44 renders a web page based on the response, and the display processing unit 45 displays the rendered web page in the web page display area of the web browser screen (step S212).

  The above is the description of the second embodiment. In the description of FIG. 9, the display of the progress status of the response received from the Web server B is not particularly mentioned, but here, whether or not the progress status is displayed is not particularly specified. There may be.

  In the description of FIG. 9, a case where screen transition based on an operation from the menu bar is prohibited by controlling some functions (buttons, display area, etc.) of the menu bar on the Web browser screen to be hidden is described. However, screen transition based on the operation from the menu bar may be prohibited by invalidating a part of the operation from the menu bar. For example, if the pressing of the back button and the forward button is disabled, the same processing as described above can be performed.
