[Exemplary Processing on Individual Portions at Remote Access]

FIGS. 5 to 7 are sequence diagrams illustrating exemplary flows of processing of the image forming apparatus 1, the terminal apparatus 2, and the web server 3, at remote access. FIG. 8 is a diagram illustrating an exemplary menu screen 61. FIG. 9 is a diagram illustrating an exemplary large-sized web page 62. FIG. 10 is a diagram illustrating an exemplary small-sized web page 63. FIGS. 11A to 11C are diagrams for illustrating exemplary web page adjustment processing.

Next, processing on individual portions in FIG. 4 will be described more specifically with an exemplary case where the terminal apparatus 2 remotely accesses the image forming apparatus 1 and uses the web browser of the image forming apparatus 1.

A user starts the client program 2P1 on the terminal apparatus 2 in advance. Subsequently, the user inputs an identifier (for example, IP address) of the image forming apparatus 1 and a remote access command.

In response to this, a remote access request is issued from the terminal apparatus 2 to the image forming apparatus 1 (#731 and #701 in FIG. 5), and thus, the image forming apparatus 1 and the terminal apparatus 2 establish (#702 and #732) connection (remote connection) with each other in a known method.

Once the connection is established, the touch panel display 10e is locked (#703) in parallel with remote operation of the image forming apparatus 1. With this mechanism, the touch panel display 10e stops receiving operation until it is unlocked.

The screen data generation unit 102 transmits, as screen data 5B, screen data for displaying a predetermined screen, to the terminal apparatus 2. In the present embodiment, the screen data of the menu screen 61 are transmitted (#704). As illustrated in FIG. 8, buttons 611 are arranged on the menu screen 61. The buttons 611 are used to select from the functions included in the image forming apparatus 1, such as copier, a fax machine, and a web browser.

On the terminal apparatus 2, the display processing unit 202 receives the screen data 5B (#733), and thereafter, displays the menu screen 61 on the touch panel display 20e (#734) on a basis of the screen data 5B. The user touches the button 611 that corresponds to the web browser.

In response to this, the operation data transmission unit 201 receives the operation details (#735), and transmits data indicating the operation to the image forming apparatus 1 (#736) as operation data 5A. In this case, data indicating the touch and the position of the touch are transmitted.

Upon receiving the operation data 5A (#705), the remote operation handling unit 101 on the image forming apparatus 1 handles user operation on a basis of the operation data 5A. In this case, the web browser program 1P2 is started (#706).

In a case where the web browser program 1P2 is started in response to the user operation on another apparatus (terminal apparatus 2 in the present embodiment) that is executing remote access, the mode switching unit 122 and the user agent data acquisition unit 123 execute the following processing.

The mode switching unit 122 switches a display mode to the mode displayed as the default mode data 5D (#707). Specifically, in a case where the remote access mode is displayed as the default mode data 5D, the current mode data 5C is updated to display the remote access mode. In a case where the adjustment mode is displayed, the current mode data 5C is updated to display the adjustment mode.

The user agent data acquisition unit 123 issues a request for the user agent data 5E to the terminal apparatus (#708), and receives the requested data (#709).

On the terminal apparatus 2, when the user agent data transmission unit 203 receives a request for the user agent data 5E from the image forming apparatus 1 (#737), the user agent data transmission unit 203 transmits the requested data (#738). The user agent data 5E indicates the product name and the version of the web browser of the terminal apparatus 2, an IP address of the terminal apparatus 2, together with resolution and pixel density of the touch panel display 20e. The unit of pixel density is “PPI” representing “pixel per inch”.

In a case where no remote access is being executed, the display mode remains to be the normal mode. In this case, the user agent data 5E are not obtained.

On the image forming apparatus 1, the web page data acquisition unit 124 obtains a web page file from the web server 3 in a manner described below.

The web page data acquisition unit 124 issues a request for a web page to the web server 3 (#710 in FIG. 6) according to the URL. Specifically, in a case where, immediately after the start of the web browser program 1P2, there is a web page set as a homepage, the web page data acquisition unit 124 issues a request for this web page, to the web server 3. In another case where there is no web page set as a homepage, the web page data acquisition unit 124 issues a request, to the web server 3, for a web page specified with URL, or the like, later by the user by operating the terminal apparatus 2. Although not illustrated in the sequence diagrams in FIGS. 5 to 7, data indicating operation details are transmitted, as the operation data 5A, from the terminal apparatus 2 to the image forming apparatus 1 and request for this web page is issued to the web server 3.

A web page request is issued with a known method. For example, the web page data acquisition unit 124 transmits a hypertext transfer protocol (HTTP) request to the web server 3. The HTTP request indicates a web page address, a user agent of the client, or the like. In a case where the user agent data 5E has been obtained by the user agent data acquisition unit 123, the web page data acquisition unit 124 writes the user agent indicated on the user agent data 5E, into the HTTP request. With this operation, a portion or whole of the user agent data 5E would be transmitted to the web server 3. In a case where the user agent data 5E has not been obtained by the user agent data acquisition unit 123, the web page data acquisition unit 124 writes the user agent of the image forming apparatus 1 itself, into the HTTP request.

When the web server 3 receives the HTTP request (#751), the web server 3 issues a request (#752) toward the request-originating side for other information that is not indicated in the HTTP request, and obtains the information (#753), as required.

The web page data acquisition unit 124 receives the request (#711), and then, returns attribute data 5F indicating requested information, to the web server 3 in the following manner (#712). In a case where the user agent data 5E has been obtained by the user agent data acquisition unit 123, the web page data acquisition unit 124 transmits data indicating information indicated on the user agent data 5E to the web server 3, as the attribute data 5F. In other cases, the web page data acquisition unit 124 transmits data indicating the attribute of the image forming apparatus 1, as the attribute data 5F.

By steps #710 to #712 and steps #751 to #753, information, particularly on the web page address, and on display resolution, is issued for notification from the image forming apparatus 1 to the web server 3. Hereinafter, the resolution notified from the image forming apparatus 1 will be referred to as “resolution Ra”.

Subsequently, the web server 3 transmits a file 5G of the web page according to the HTTP request to the image forming apparatus 1 (#754) in the following manner, and then, the web page data acquisition unit 124 of the image forming apparatus 1 receives the file 5G (#713).

When the web server 3 receives a request for a web page for managing data stored in a cloud storage, for example, the web server 3 transmits a file for displaying a large-sized web page 62 illustrated in FIG. 9, as the file 5G, in a case where the resolution Ra is predetermined resolution Rb (for example, 600×480 pixel) or more. In contrast, in a case where the resolution Ra is below the predetermined resolution Rb, the web server 3 transmits a file for displaying the small-sized web page 63 as illustrated in FIG. 10, as the file 5G.

The large-sized web page 62 is designed to match the resolution of the display of a personal computer or a tablet computer, and the small-sized web page 63 is designed to match the resolution of the display of a smartphone. Accordingly, there are more objects arranged on the large-sized web page 62 than the case of the small-sized web page 63.

With the above-described processing, in the normal mode or adjustment mode, the web page data acquisition unit 124 obtains a file of the large-sized web page 62, as the file 5G, from the web server 3. In the remote access mode, the web page data acquisition unit 124 obtains a file of the small-sized web page 63, as the file 5G.

When the file 5G has been obtained by the web page data acquisition unit 124 on the image forming apparatus 1 and in a case where the display mode is the adjustment mode, web page adjustment processing is executed by the web page adjustment unit 125 (#714). This processing will be described with an exemplary case of adjusting the web page 64 in FIG. 11A.

The web page adjustment unit 125 rewrites the file 5G so as to enlarge the web page 64. Magnification of enlargement may be preset or may be set to (Db/Da) times. where, “Da” represents the pixel density of the touch panel display 10e of the image forming apparatus 1, and “Db” represents the pixel density of the touch panel display 20e of the terminal apparatus 2.

For example, in a case where (Da/Db) is “4”, the web page adjustment unit 125 rewrites the file 5G such that the web page 64 is vertically and horizontally enlarged four times, as illustrated in FIG. 11B. Hereinafter, the enlarged web page 64 will be referred to as a “web page 65”.

Alternatively, it is allowable to enlarge the web page 64 according to individual resolution of the touch panel display 10e and the touch panel display 20e. For example, in a case where the resolution of the touch panel display 10e is (Wa×Ha) and the resolution of the touch panel display 20e is (Wb×Hb), it is allowable to vertically and horizontally enlarge a button 641 (Wa/Wb) times. Alternatively, it is allowable to enlarge the size (Ha/Hb) times. Still alternatively, it is allowable to vertically enlarge the size (Wa/Wb) times, and horizontally enlarge the size (Ha/Hb) times.

Returning to FIG. 6, the screen data generation unit 102 generates the screen data 5B in the following manner (#715).

In a case where the display mode is the remote access mode, the screen data generation unit 102 generates bitmap data by rendering the web page on a basis of the file 5G obtained by the web page data acquisition unit 124. In a case where the display mode is the adjustment mode, the screen data generation unit 102 generates bitmap data by rendering the web page on a basis of the file 5G rewritten by the web page adjustment unit 125. The data generated in this manner are the screen data 5B.

Subsequently, the screen data transmission unit 103 transmits the screen data 5B to the terminal apparatus 2 (#716).

On the terminal apparatus 2, the display processing unit 202 receives the screen data 5B (#739), and then, displays the web page on the touch panel display 20e (#740) on the basis of the screen data 5B.

At this time, in a case where the display mode is the remote access mode, a web page for the smartphone, such as the small-sized web page 63 (refer to FIG. 10) is displayed on the touch panel display 20e.

In contrast, in a case where the display mode is the adjustment mode, an enlarged web page, such as the web page 65 (refer to FIG. 11B), is displayed on the touch panel display 20e. Since it is enlarged, merely a portion of the web page might be displayed at a time in some cases, as illustrated in FIG. 11C. In this case, the user can display the remaining portions by scrolling the web page 65 with drag or flick operation.

Thereafter, each time the user specifies a web page by selecting a hyperlink, or with other methods, data for the operation details are transmitted as the operation data 5A from the terminal apparatus 2 to the image forming apparatus 1. Subsequently, the selected web page is requested from the image forming apparatus 1 to the web server 3, a web page corresponding to the current display mode (one of the remote access mode and the adjustment mode) is provided to the terminal apparatus 2.

When finishing the remote access, the user inputs a disconnect instruction into the terminal apparatus 2. When the terminal apparatus 2 receives the instruction (#741), the image forming apparatus 1 and the terminal apparatus 2 disconnect (#717 and #742) connection (remote connection) established in steps #702 and #732.

In response to this, the mode switching unit 122 switches, on the image forming apparatus 1, the display mode to the normal mode (#718).

After disconnection, remote operation toward the image forming apparatus 1 by the terminal apparatus 2 is finished, and then, the touch panel display 10e is unlocked (#719 in FIG. 7).

The web page data acquisition unit 124 issues a request for the web page being displayed on the terminal apparatus 2 immediately before disconnection, to the web server 3 (#720). Thereafter, the web page data acquisition unit 124 and the web server 3 execute processing (#722 to #724, and #755 to #758) similar to steps #711 to #713 and steps #751 to #754, respectively.

Note that the image forming apparatus 1 issues a notification of resolution of the touch panel display 10e of the image forming apparatus 1 itself, instead of the resolution of the touch panel display 20e of the terminal apparatus 2, to the web server 3. In response to this, the web server 3 transmits, to the image forming apparatus 1, a web page file for a personal computer, such as the large-sized web page 62 (refer to FIG. 9) instead of the web page file for a smartphone, such as the small-sized web page 63 (refer to FIG. 10).

Then, when the web page data acquisition unit 124 receives the web page file (#723) on the terminal apparatus 2, the web page display unit 126 displays the received web page on the touch panel display 10e as usual according to the file (#724).

FIG. 12 is a flowchart illustrating an exemplary processing flow based on the server program 1P1. FIGS. 13 to 14 are flowcharts illustrating exemplary processing flows based on the web browser program 1P2.

Next, an overall processing flow of the image forming apparatus 1 will be described with reference to the flowchart.

As illustrated in FIG. 12, the image forming apparatus 1 executes processing of providing a remote access service to the terminal apparatus 2 on a basis of the server program 1P1.

After receiving request for remote access from the terminal apparatus 2 (#11: Yes), the image forming apparatus 1 establishes connection with the terminal apparatus 2 (#12). Subsequently, the image forming apparatus 1 transmits data for displaying the menu screen 61 (refer to FIG. 8) as the screen data 5B, to the terminal apparatus 2 (#13), and together with this, locks the touch panel display 10e (#14).

Connected with the terminal apparatus 2, the image forming apparatus 1 receives the operation data 5A from the terminal apparatus 2 (#15: Yes), and executes the processing in the following manner according to the information indicated by the operation data 5A.

In a case where the operation data 5A indicates the pressing of the button 611 that starts the web browser (#16: Yes), the image forming apparatus 1 starts the web browser program 1P2 (#17). The image forming apparatus 1 subsequently executes the web browser program 1P2 in parallel with the server program 1P1. The processing flow executed by the web browser program 1P2 will be described below with reference to FIGS. 13 to 14.

Alternatively, in a case where information displayed as the operation data 5A is related to operation of the web browser (#18: Yes), the operation data 5A is passed to the web browser program 1P2 (#19).

In a case where the file 5G of the web page is obtained by the web browser program 1P2 (#20: Yes) after processing of step #17 or step #19, and when remote access is not being executed by the terminal apparatus 2 (#21: No), this web page is displayed by the touch panel display 10e on a basis of the file 5G (#22). In contrast, when remote access is being executed by the terminal apparatus 2 (#21: Yes), bitmap data of this web page is generated on a basis of the file 5G (#23), and the data is transmitted as the screen data 5B to the terminal apparatus 2 (#24).

In a case where connection established in step #12 is disconnected (#25: Yes), the image forming apparatus 1 issues a notification of disconnection to the web browser program 1P2 (#26), and together with this, unlocks the touch panel display 10e (#27).

While providing remote access service, the image forming apparatus 1 appropriately executes processing of steps #11 to #26.

Moreover, the image forming apparatus 1 executes processing in the following manner with a method illustrated in FIGS. 13 to 14 on the basis of the web browser program 1P2.

After starting of the web browser program 1P2 (#31: Yes), in a case where the image forming apparatus 1 is remotely accessed by the terminal apparatus 2 (#32: Yes), the image forming apparatus 1 issues a request for the user agent data 5E, to the terminal apparatus 2 (#33), and receives the requested data (#34). Then, the image forming apparatus 1 switches the display mode to one of the remote access mode and the adjustment mode (#35).

In a case where a homepage is set on the web browser program 1P2 (#36: Yes), the image forming apparatus 1 issues a request for the web page as the homepage, to the web server 3 (#37).

The image forming apparatus 1 transmits a user agent, or the like, to the web server 3 at the time of issuance of the request for the web page, or in response to the request from the web server 3 (#40 to #42). Specifically, in a case where the display mode is the remote access mode (#40: Yes), the image forming apparatus 1 transmits (#41) a user agent (at least resolution of the touch panel display 20e in the present embodiment) of the terminal apparatus 2, received in step #34. In a case where the display mode is not the remote access mode (#40: No), the image forming apparatus 1 transmits (#42) a user agent of itself (at least resolution of the touch panel display 10e in the present embodiment).

The image forming apparatus 1 receives the file 5G of the requested web page, from the web server 3 (#43).

In a case where the display mode is the adjustment mode (#44: Yes in FIG. 14), the image forming apparatus 1 rewrites the received file 5G (#45) to adjust the web page. Exemplary adjustment methods are as described in FIGS. 11A to 11C.

The file 5G is rewritten as required and thereafter is used by the server program 1P1 so as to display the web page onto the touch panel display 10e, or onto the touch panel display 20e of the terminal apparatus 2 (#46). The usage is as described in steps #21 to #24 in FIG. 12.

Processing in steps #32 to #34 is executed merely once after the start of the web browser program 1P2. Automatic access to a homepage (#37 to 46) is fundamentally executed merely once after the start of the web browser program 1P2.

Alternatively, when the operation data 5A is given from the server program 1P1, and in a case where operation to move from a current web page (or, a blank page) to other web page is indicated in the operation data 5A (#38: Yes), the image forming apparatus 1 issues a request for the other web page, to the web server 3 (#39). Thereafter, processing is similar to the processing in accessing to the homepage (#40 to #46).

Alternatively, when disconnection of the connection is notified from the server program 1P1 (#47: Yes), the image forming apparatus 1 switches the display mode to the normal mode (#48). Subsequently, the image forming apparatus 1 issues a request for the web page being displayed by the touch panel display 20e of the terminal apparatus 2 immediately before disconnection of the connection, to the web server 3 (#49). Thereafter, processing is similar to the processing in accessing to the homepage (#40 to #46). As a result, the web page is displayed on the touch panel display 10e of the image forming apparatus 1 itself, as usual.

Processing in steps #38 to #49 is appropriately executed until the web browser program 1P2 is finished.

According to the present embodiment, it is possible to provide web content more suitably than before to the terminal apparatus 2 in a case where the terminal apparatus 2 remotely accesses the image forming apparatus 1 to use the web browser of the image forming apparatus 1.

In the present embodiment, the server program 1P1 and the web browser program 1P2 are configured as independent programs. It is, however, allowable to configure them as one program.

In the present embodiment, the image forming apparatus 1 issues a notification of display resolution to the web server 3, and the web server 3 provides the file 5G of the web page corresponding to the resolution. Alternatively, however, it is also allowable to configure such that the image forming apparatus 1 issues a notification of another attribute and the web server 3 provides the file 5G of the web page corresponding to that attribute.

For example, the image forming apparatus 1 issues a notification of the name of the operating system (OS) of the terminal apparatus 2 in a case where the mode is the remote access mode, and issues a notification of the name of the OS of the image forming apparatus 1 itself in cases where the mode is other than the remote access mode. The web server 3 determines whether the OS is for a smartphone on a basis of the notified name of the OS. In a case where the OS is for a smartphone, the web server 3 transmits the file 5G of a web page for a smartphone (for example, the small-sized web page 63 in FIG. 10). In a case where the OS is not for smartphones, the web server 3 transmits the file 5G for a web page for a personal computer (for example, the large-sized web page 62 in FIG. 9).

Alternatively, the image forming apparatus 1 issues a notification of the size (inch) of the touch panel display 20e of the terminal apparatus 2 in a case where the mode is the remote access mode, and issues a notification of the size of the touch panel display 10e of the image forming apparatus 1 itself in cases where the mode is other than the remote access mode. In a case where the size is below a predetermined size, the web server 3 transmits the file 5G of a web page for a smartphone. In a case where the size is the predetermined size or above, the web server 3 transmits the file 5G for a web page for a personal computer.

In the present embodiment, the web page adjustment unit 125 executes web page adjustment processing in the adjustment mode alone. It is, however, allowable to configure such that the web page adjustment unit 125 executes the processing in a case where remote access is being executed and resolution of the touch panel display 20e of the terminal apparatus 2 is below predetermined resolution (for example, resolution of the touch panel display 10e).

In the present embodiment, the touch panel display 10e of the image forming apparatus 1 is locked during a period of remote access by the terminal apparatus 2 to the image forming apparatus 1. Alternatively, the touch panel display 10e need not be locked. In this case, it would be appropriate to display the web page also on the touch panel display 10e.

In the present embodiment, the web server 3 distributes a web page, as web content, to the image forming apparatus 1. The present invention is also applicable to the case where a moving image, or the like, is distributed as web content.

Other than the above, it is possible to appropriately modify a configuration, processed content, processing order, screen configuration, or the like, of overall portions or an individual portion of the web page browsing system 100, the image forming apparatus 1, and the terminal apparatus 2, according to the scope of the present invention.

Although the present invention has been described and illustrated in detail, it is clearly understood that the same is by way of illustrated and example only and is not to be taken by way of limitation, the scope of the present invention being interpreted by terms of the appended claims.
