Description

  The present invention relates to an information processing apparatus and a program.

  Conventionally, in each terminal device (PC terminal) connected to a network such as an in-house LAN, the individual terminal device independently activates and executes an application such as document creation or table creation, and various types generated in accordance with this. The file is also stored in its own storage device in the terminal device, or is stored in an external storage medium such as a magnetic disk, optical disk, or small semiconductor memory, or transferred to a storage device managed by a server device on the network and stored. Yes.

  In such a conventional server / client system, the generated file is managed in each terminal device itself. Therefore, if the terminal device is lost or illegally taken out and put into the hands of a third party, the saved file is stored. May be read out and important information and confidential information may be leaked.

  In addition, if each terminal device starts and executes an application independently, it is necessary to update, change, and add the application for each terminal device, which is cumbersome and expensive. .

  For this reason, in recent server-client systems, all applications that are input / output / displayed on each terminal device are started and executed on the server device, and all generated files associated therewith are also managed on the server device side. SBC (Server Based Computing) system has been introduced (see, for example, Patent Document 1 and Patent Document 2).

  In such a server-based computing system, drawing data of application software executed on the server device side is transferred to a terminal device (client device), and the drawing data is displayed on the client device ( For example, see Patent Document 3.)

  Recently, even in this server-based computing system, it is considered to use a mobile terminal having a small display screen as a client device, such as a mobile phone (see, for example, Patent Document 4).

  The CPU 11 stores a system program stored in the memory 12 in advance, or read and stored in the memory 12 from the external storage medium 18a, or read and stored in the memory 12 from a program server on the network N. In accordance with various application programs, the storage unit 13 is used as a working memory to control the operation of each part of the circuit. The client device 20 (20P, 20M) is received via the key input signal from the input unit 16 or the transmission / reception control unit 14. ),... Are started and executed in response to a processing command signal corresponding to a user operation (input event).

  In the server device 10, various data generated in accordance with an application program that is activated and executed in response to an input event signal from the client device 20 is stored in the memory 12 in association with the user ID, for example. Further, the drawing data for display is written in the virtual frame buffers (FB) 12a, 12b,... Prepared in the memory 12 corresponding to the client devices 20. Then, it is converted into transfer drawing data obtained by extracting an image change portion (difference) between the previous drawing data and the current drawing data, transferred from the transmission / reception control unit 14 to the client device 20 and displayed.

  FIG. 3 is a block diagram showing a circuit configuration of the client device 20 (20P, 20M) in the server-based computing system.

  The client device 20 includes a CPU 21 as a computer. The CPU 21 includes a memory 22 formed of a flash ROM, a storage unit 23 formed of a RAM, a transmission / reception control unit 24 with the server device 10, and a display controller 25a via a bus 27. A storage medium read / write unit 28 for reading / writing data is connected to the display unit 25, the input unit 26, and an external storage medium 28a such as a memory card.

  The display controller 25a includes a frame buffer (FB) 25b, and the frame buffer (FB) 25b is generated and transferred by the server device 10 and decompressed, for example, a VGA (Video Graphics Array) size drawing. Data is stored. The display controller 25 a cuts out drawing data stored in the frame buffer (FB) 25 b at a display position corresponding to a user operation and an area corresponding to the display screen size of the display unit 25, and displays it on the display unit 25. Let

  The CPU 21 stores the memory 23 in accordance with a system program (client control program) stored in the memory 22 in advance, or read from the external storage medium 28a into the memory 22 or read from the program server on the network N into the memory 22. Is used as a working memory to control the operation of each part of the circuit. A key input signal from the input unit 26, an application response signal received from the server device 10 via the transmission / reception control unit 24, transfer drawing data, display position / The client control program is activated and executed according to the area information.

  In this server-based computing system, drawing data generated by the server device 10 in response to an event such as a key input from the client device 20 is updated after each drawing data is generated and updated. The difference area is extracted and transferred to the client device 20 as transfer drawing data. Then, with respect to the drawing data already stored and displayed in the frame buffer (FB) 25b in the client device 20, only the image change area is sequentially rewritten and displayed and updated. As a result, the amount of data transferred from the server device 10 to the client device 20 is greatly reduced.

  Next, in the server device 10 of the server-based computing system having the above configuration, when a text input area is included in the drawing data generated in response to an input event from the client device 20, the drawing data A text input area size changing function for changing the size of the text input area so as to eliminate the useless blank portion and updating the drawing will be described.

  FIG. 4 shows the drawing data G generated by the server device 10 in response to an input event of the client device 20, the text input area TA existing on the drawing data G, and the client device 20 in the server-based computing system. It is a figure which shows the relationship with the display screen area | region E cut out and displayed according to user operation of.

  The drawing data G generated by the server device 10 is generated, for example, in a VGA size and written into the frame buffer (FB) of the client device 20. In the client device 20 having a small display screen (25) such as a cellular phone, the display screen area E is vertically and horizontally based on the display start point coordinates (DX, DY) moved to an arbitrary position according to a user operation. The display screen area E is set by the width (DH × DW) and is cut out from the drawing data G and displayed on the display unit 25.

  Here, when the text input area TA is included in the drawing data G generated by the server device 10 and no character is input in the text input area TA as shown in FIG. 4A, for example. The server device 10 changes the size by leaving the text input area TA of the drawing data G, for example, as shown in FIG. 4B, and changes the size in the display screen area E of the client device 20. The drawing is updated so that more information OA is included.

  FIG. 5 is a flowchart showing server control processing by the server device 10 of the server-based computing system.

  FIG. 6 is a flowchart showing event processing accompanying server control processing of the server device 10.

  FIG. 7 is a flowchart showing text area size change processing accompanying server control processing and event processing of the server device 10.

  FIG. 8 is a flowchart showing client control processing by the client device 20 of the server-based computing system.

  First, in the client device 20, when a connection request to the server device 10 is instructed by a user operation of the input unit 26, a connection establishment processing request is transmitted from the transmission / reception control unit 24 to the server device 10 (step C1 in FIG. 8). ) And a connection establishment process based on an authentication process with the server device 10 is executed (step C2).

  When the server apparatus 10 receives the connection establishment process request transmitted from the client apparatus 20 (step S1 in FIG. 5), it is based on the authentication process with the client apparatus 20 that is the connection request source. A connection establishment process is executed (step S2).

  As a result, when a connection between the server device 10 and the client device 20 is established, an input event such as opening an arbitrary Web page is accepted in response to a user input on the client device 20 (step in FIG. 8). C3 (YES)), the input event is transmitted to the server device 10 (step C4).

  When the server device 10 receives an input event for opening, for example, a Web page transmitted from the client device 20 (step S3 (YES) in FIG. 5), the server device 10 responds to an application program such as a Web browser. An operation signal corresponding to the input event is transmitted (step S4).

  Here, processing corresponding to the input event is performed by the application program corresponding to the input event, in this case, a user-specified Web page written in HTML is opened, and the drawing data G is the client device of the event input source 20 is read into the frame buffer (FB) 12a in the memory 12 corresponding to 20 (step S5 (YES) → S6), it is determined whether or not the text input area TA is included in the drawing data G (step S5). S7).

  When it is determined that the text input area TA is not included in the HTML drawing data G read this time (step S7 (NO)), the drawing data G is converted into transfer drawing data and the event input source. To the client device 20 (step S10).

  When the client device 20 receives, for example, the drawing data G of the Web page transmitted from the server device 10 (step C5 (YES) in FIG. 8), the previous data already stored in the frame buffer (FB) 25b is received. The difference image with the drawing data G is written in the frame buffer (FB) 25b. Then, the display controller 25a cuts out the display screen area E corresponding to the display start point coordinates (DX, DY) according to the user operation and the vertical / horizontal length (DH × DW) according to the display screen size of the display unit 25, The data is output and displayed on the display unit 25 (step C6).

  For example, in the initial stage of opening a web page, drawing data of the entire page is received as a difference image and written to the frame buffer (FB) 25b, and thereafter the drawing content of the web page is updated. Only the difference image of the drawing updated part is received together with the position information, and the drawing data G stored in the frame buffer (FB) 25b is updated.

  Thus, in a state where the drawing data G generated and transferred by the server device 10 is displayed on the display unit 25 of the client device 20 according to the display screen area E, an input event corresponding to a user operation on the drawing data G is received. If it is transmitted to the server device 10 (step C3 (YES) → C4), the event processing in FIG. 6 is started in the server device 10 in response to the input event from the client device 20 (FIG. 5). Steps S3 to S5 (NO) → SA).

  In the event processing of the server device 10 shown in FIG. 6, the content of the input event from the client device 20 is an input event with focus F on the text input area TA on the drawing data G, or It is determined whether the event is an input event in which the focus F is removed from the text input area TA or other than that (steps A1 and A2).

  Here, when it is determined that the input event from the client device 20 is not an input event for applying or removing the focus F to the text input area TA on the drawing data G (step A1 (NO) → A2 (NO)), other processing corresponding to the input event is executed (step A3). If the content of the drawing data G is changed by the process according to the input event (step A4), the previous drawing data written in the frame buffer 12a corresponding to the client device 20 that is the event input source. G is updated (step A5), and the difference image data is transmitted to the client device 20 (step A6).

  Thus, the drawing data G generated and transferred by the server device 10 in response to a user input event in the client device 20 is stored in the frame buffer (FB) 25b while being updated sequentially, and a display screen area corresponding to a user operation E is displayed on the display unit 25.

  On the other hand, when the server device 10 receives an input event such as opening a new Web page from the client device 20 (step S3 (YES) in FIG. 5), the Web page specified by the user described in HTML is displayed. When the drawing data G is opened and read into the frame buffer (FB) 12a corresponding to the client device 20 that is the event input source (steps S4, S5 (YES) → S6), the drawing data G contains text If it is determined that the input area TA is included (step S7 (YES)), the process proceeds to the text area size changing process in FIG. 7 (step SB).

  When the text area size changing process shown in FIG. 7 is started, an acquisition process of the character string input to the text input area TA on the drawing data G is executed (step B1), and the text input area TA It is determined whether or not a character has been input (step B2).

  Here, for example, as shown in FIG. 4A, when it is determined that no character is input in the text input area TA on the drawing data G (step B2 (YES)), for example, FIG. As shown in (B), the height in the line direction of the text input area TA is changed to be small corresponding to the height of one line, and unnecessary blank portions are reduced to the minimum (step B3).

  On the other hand, if it is determined that characters have already been input in the text input area TA on the drawing data G (step B2 (NO)), the number of all the input characters is multiplied by the font size. Is divided by the horizontal width of the text input area TA, and the rounded-up value of the division result is calculated as the number of lines in the text input area TA after the change (step B4). ).

  Then, the height of the text input area TA in the line direction is changed to be small corresponding to the number of lines necessary for the current number of input characters calculated in the step B4, and the useless blank space is minimized. (Step B5).

  The series of text area size change processing (step SB in FIG. 5) is sequentially executed for all text input areas TA existing in the drawing data G (steps SB → S8 → SB). ).

  Thus, when the resize processing for compressing the useless blank portion is executed for all the text input areas TA existing in the drawing data G (step S8 (YES)), the resize of the text input area TA is changed. A drawing update process for re-laying out other information OA is executed for the subsequent drawing data G (step S9), and the drawing data G after the drawing update is transmitted to the event input source client device 20 (step S10). ).

  As a result, the text input area TA on the drawing data G displayed on the display unit 25 of the client device 20 is displayed with its useless blank portion compressed to a minimum, and the text input area TA. More other information OA is displayed in accordance with the area where has become smaller, and the amount of information obtained by the user can be increased.

  Thereafter, in the client device 20, the text input area TA on the drawing data G displayed on the display unit 25 is focused on by the user operation of the input unit 26, and the input event signal is sent to the server device 10. (Step C3 (YES) → C4 in FIG. 8), the server device 10 proceeds to the event processing in FIG. 6 (steps S3 to S5 (NO) → SA).

  Then, in this event processing, first, it is determined that the content of the input event from the client device 20 is an input event having the focus F with the text input area TA on the drawing data G as the operation target (see FIG. 6 (step A1 (YES)), it is determined whether or not there is a guidance display of “character input present” to be described later in the text input area TA (step A7).

  Here, when it is determined that there is a guidance display of “character input present” (step A7 (YES)), the guidance display is deleted from the text input area TA (step A8), and then the text input is performed. The font size of characters in the area TA is increased by N points (for example, 2 points) (step A9), and the text input area TA is resized according to the increase in font size (step AB). ).

  That is, in the text area size changing process, as described above, when no character is input in the text input area TA with the focus F, the size of the area TA is set to the height of one line. In the case where a character is input, the size of the area TA is set to a height corresponding to the number of lines in which the character string obtained by increasing the font size by N points is accommodated (step B1 to B3 in FIG. 7). It is greatly changed (step B2 (NO) → B4, B5).

  When it is determined that the content of the drawing data G has been changed by changing the size of the text input area TA by the size changing process of the text input area TA (step A4 in FIG. 6). (YES)), the drawing data G is updated with the other information OA re-laid in accordance with the size change of the text input area TA (step A5), and the difference image data is transmitted to the client device 20 (step A5). Step A6).

  Thereby, when the focus F is focused on the text input area TA on the drawing data G displayed on the display unit 25 of the client device 20, the font size in the text input area TA is increased and changed. At the same time, the size of the area TA is changed in accordance with the increase in the font size, and the characters in the area TA are further reduced while minimizing unnecessary blank portions of the text input area TA. It can be displayed easily.

  On the other hand, when the focus F is focused on the text input area TA on the drawing data G displayed on the display unit 25 of the client device 20, the focus F is removed by the user operation of the input unit 26, and the input is performed. When the event signal is transmitted to the server device 10 (step C3 (YES) → C4 in FIG. 8), the server device 10 again proceeds to the event processing in FIG. 6 (steps S3 to S5 (NO) → SA). ).

  Then, in this event processing, first, it is determined that the content of the input event from the client device 20 is an input event in which the focus F is out of the text input area TA on the drawing data G (step A2 (YES) )), The font size of the character in the text input area TA is changed by N points (for example, 2 points) lower (step A10), and the text input area TA size changing process is performed in accordance with the lowering of the font size. It is executed (step AB).

  That is, in the text area size changing process, as described above, when no character is input in the text input area TA with the focus F, the size of the area TA is set to the height of one line. If a character is input, the size of the area TA is set to a height corresponding to the number of lines in which a character string obtained by lowering the font size by N points fits. Small change is made (step B2 (NO) → B4, B5).

  Then, a guidance display of “character input present” indicating that a character is described in the area TA is set by overwriting with respect to the small-sized text input area TA (step A11 in FIG. 6). ).

  When it is determined that the contents of the drawing data G have been changed by changing the size of the text input area TA by the size changing process of the text input area TA (step A4 (YES)) In accordance with the change in the size of the text input area TA, the drawing data G is updated to other information OA (step A5), and the difference image data is transmitted to the client device 20 (step A6). .

  As a result, when the focus F is removed from the text input area TA on the drawing data G displayed on the display unit 25 of the client device 20, the font size in the text input area TA is reduced and changed. In accordance with the change in the font size, the size of the area TA is changed and the guidance display “character input is present” is performed. Therefore, when the text input area TA is not an operation target, the occupation ratio of the display screen area E by the area TA can be suppressed as much as possible, and more other information OA can be displayed. Even if the characters cannot be read, the presence of the text can be easily confirmed by the guidance display “character input is present”.

  Thereafter, when an operation to end the connection with the server device 10 is performed in the client device 20 (step C7 (YES) in FIG. 8), a connection end processing signal is transmitted to the server device 10 ( Step C8). When the server device 10 receives the connection end processing signal transmitted from the client device 20 (step S11 (YES) in FIG. 5), the connection with the client device 20 is ended (step S12). .

  Therefore, according to the size changing function of the text input area TA by the server device 10 of the server-based computing system having the above-described configuration, the text input area TA is added to the drawing data G generated in response to the input event from the client device 20. Is included, it is determined whether or not a character is input in the text input area TA, and the margin portion of the text input area TA in the drawing data G is reduced according to the determination result of the character input. Resize as follows. Specifically, if there is no character input, the size is changed to leave the height of one line, and if there is character input, the size is changed to leave the height corresponding to the number of lines necessary to display the character. . Then, the drawing data G is updated in a state where the size of the text input area TA has been changed, and transmitted to the event input source client device 20.

  As a result, the client device 20 can compress the useless blank portion of the text input area TA, and can obtain drawing data G in which more information OA has been laid out again in the compressed portion. Even if the client device 20 is a portable terminal having a small display screen area E, the desired information can be easily displayed without the display screen (25) being occupied by the text input area TA.

  Further, according to the size changing function of the text input area TA by the server device 10 of the server-based computing system having the above-described configuration, the input specifying the text input area TA on the drawing data G from the client device 20 as an operation target. When an event is received, the font size of the text input area TA is increased by N points, and the text input area TA is increased by the number of lines necessary for displaying the character with the increased font size accordingly. Resize to leave Then, the drawing data G is updated in a state where the size of the text input area TA has been changed, and transmitted to the event input source client device 20.

  As a result, the client device 20 can display characters in the area TA in an easy-to-read manner while minimizing a useless blank portion of the text input area TA to be operated.

  Further, according to the size change function of the text input area TA by the server device 10 of the server-based computing system having the above configuration, the client device 20 can designate the text input area TA on the drawing data G as an operation target. When a removed input event is received, the font size of the text input area TA is reduced by N points, and the number of lines necessary for displaying the text input area TA with the font size reduced accordingly. Resize leaving only the height. Then, the drawing data G is updated in a state where the size of the text input area TA has been changed, and transmitted to the event input source client device 20.

  Thereby, in the client device 20, when the text input area TA is not an operation target, the occupation ratio of the display screen area E by the area TA can be suppressed as much as possible, and more other information OA can be displayed.

  Further, when the font size in the area TA is reduced and the area TA is resized because the text input area TA is excluded from the operation target, the guidance “character input is present” is set in the area TA. Therefore, even if characters in the area TA whose size has been changed to a small size cannot be read, the presence of the text can be easily confirmed by the guidance display “character input is present”.

  The server-based computing system of the above embodiment transfers the drawing data G generated by the server device 10 in response to an input event from the client device 20 from the server device 10 to the event input source client device 20. The client device 20 is configured to cut out and display on the display screen area E corresponding to the display unit 25.

  On the other hand, as another form of server-based computing system, the client device 20 sends the current event on the drawing data G generated by the server device 10 each time the input event is transmitted to the server device 10. The position and size information (DX, DY, DW, DH) of the display screen area E of the current display screen area E is transmitted from the drawing data G generated in response to the input event. Some of the drawing data corresponding to the position and size information (DX, DY, DW, DH) is cut out, transferred to the client device 20 that is the event input source, and displayed on the display unit 25.

  Even in such other forms of server-based computing systems, the text input area TA is included in the drawing data G generated in response to an input event from the client apparatus 20 in the server apparatus 10 as in the previous embodiment. In this case, it is determined whether or not a character is input in the text input area TA, and the size of the text input area TA in the drawing data G is reduced according to the determination result of the character input. change. Then, the drawing data G is updated while the size of the text input area TA is changed, and drawing data corresponding to the position and size information (DX, DY, DW, DH) of the display screen area E is updated. By cutting and transferring to the client device 20 that is the event input source, even if the client device 20 is a portable terminal having a small display screen area E, the display screen (25) is occupied by the text input area TA. It is possible to easily display desired information without causing any trouble.
