Description

  The present invention relates to an image display control device for a multi-display.

  In recent years, users of personal computers are increasingly performing work in parallel while displaying many windows on a display. Various techniques have been proposed that allow the user to smoothly perform work in such a situation.

  For example, a technique for switching a window displayed on a screen by a dial operation has been devised (see Patent Document 1). According to this technique, the user can quickly and reliably switch the display window by a dial operation.

  In addition, for example, a technique has been devised in which a child window is shared between a plurality of parent windows, and an operation performed on one of the plurality of windows displayed on the screen is reflected on the other windows. (See Patent Document 2). According to this technique, it is not necessary to operate each child window independently, so that it is possible to eliminate waste of user operations.

  By the way, some recent PC operating systems (OS) have a multi-display function in which a screen of one personal computer is divided and displayed on each display screen of a plurality of displays constituting the multi-display system. In a multi-display environment, since the screen of one personal computer is divided and displayed on a plurality of displays, the user can view a plurality of windows displayed in a large display area at the same time. Work efficiency is improved.

FIG. 3 is a diagram illustrating a configuration related to window display control in the image display control apparatus 1. In the image display control apparatus 1, the program 100 stored on the fixed disk 14 is executed by the control unit 11, thereby creating / ending instruction receiving unit 101, window display state determining unit 102, window creating unit 103, window end Functions of the unit 104, the position detection unit 105, and the final display state table management unit 106 are realized.

  The creation / end instruction reception unit 101 receives an instruction to create a window and an instruction to close the created window among various input operations performed by the user via the operation unit 19. For example, when the user inputs an instruction to create a window for displaying / editing the file based on the designation of the file name or an instruction to close the window after ending the file being displayed / edited, The instruction is accepted. In addition, when the user inputs an instruction to create a window for displaying data existing on the network based on the address designation or an instruction to end the data display and close the window, the instruction is given. Accept. Furthermore, an instruction to create a child window based on the previously created parent window is accepted.

  When the creation / termination instruction reception unit 101 receives an instruction to create a window, the window display state determination unit 102 determines the display state of a newly created window in response to the instruction. The window display state determination unit 102 includes a display display selection unit 121.

  The display display selection unit 121 selects a display device that displays a newly created window from the plurality of display devices 21A and 21B included in the multi-display system 100. In other words, it is a processing unit that selects whether to display a newly created window in the display area 211A or the display area 211B. Hereinafter, a display device that displays a window in its display area is referred to as a “display display” of the window. That is, the display display selection unit 121 determines a display display for a newly created window.

  The window creation unit 103 gives an instruction to display the windows in the display areas 211A and 211B in a predetermined display state (that is, the display state determined by the window display state determination unit 102) to the display controllers 17A and 17B.

  The window end unit 104 gives an instruction for closing the windows displayed in the display areas 211A and 211B to the display controllers 17A and 17B.

  The position detection unit 105 detects the position of the window displayed in the display areas 211A and 211B, and the window is displayed on any of the display devices 21A and 21B included in the multi-display system 100. To identify. That is, the position detection unit 105 specifies the display display of the displayed window. Note that information specifying the display display of the window is hereinafter referred to as “display display information D”.

  The final display state table management unit 106 manages the final display state table T stored in the RAM 12. More specifically, the final display state is obtained by associating the display display information D acquired from the position detection unit 105 (more specifically, “final display display information DL” described later) with the file name or web page address. Processing to store in the table T is performed.

  However, when the window is closed (more specifically, when the creation / end instruction receiving unit 101 receives a window end instruction), the display device that displays the window in the display area is referred to as the window. Is called the “final display”. Information for specifying the final display display of the window is referred to as “final display information DL”.

  Here, the final display state table T will be described. In the final display state table T, the final display information DL is associated with information about the data displayed in the window (more specifically, the file name or web page address of the file displayed / edited in the window). 4 and FIG. 4A and FIG. 4B respectively show specific configuration examples. However, in the final display state table T shown in FIG. 4, when the final display is the first display device 21A, “1” is set as the final display information DL, and in the case of the second display device 21B. Is set to “2”. Also, here, a final display state table T (FIG. 4A) storing final display display information DL associated with a file name, and a final display storing final display display information DL associated with an address. Although the state table T (FIG. 4B) is illustrated as a separate table, the information stored in these two tables may be stored in one table.

<2. Processing action>
<2-1. Window closing process>
FIG. 5 is a flowchart showing the window end processing operation in the image display control apparatus 1 according to this embodiment. Unless otherwise specified, the following operations are performed under the control of the control unit 11.

  When it is determined that the user has input an instruction to close the window via the operation unit 19, the creation / end instruction receiving unit 101 receives the input operation (step S11).

  Subsequently, the position detection unit 105 detects the final display position of the window instructed to end in step S11, specifies the final display display of the window, and outputs the final display information DL (step S12).

  Subsequently, the final display state table management unit 106 uses the final display display information DL output in step S12 as information (file name and web page address) regarding the data displayed in the window instructed to end in step S11. The associated information is stored in the final display state table T (step S13). For example, in step S11, the creation / end instruction receiving unit 101 receives a command to close the window displaying the file name “document4.doc”, and in step S12, the position detecting unit 105 outputs “1” as the final display information DL. In this case, the final display position table management unit 142 stores final display information DL = “1” in association with the file name “document4.doc”. When the final display information DL is already stored for the file name “document4.doc”, the final display information DL for “document4.doc” is updated. For example, if the final display information DL = “2” is stored in association with the file name “document4.doc”, “1” is set instead of “2”.

  Subsequently, the window end unit 104 gives an instruction to the display controllers 17A and 17B to close the window that is instructed to end in step S11 (step S14).

  By performing the above processing when closing the window, the final display information DL for the window once created in the final display state table T can be accumulated. Further, the final display information DL can be always updated to the latest state. For example, as shown in FIG. 9, when the window W1 displaying the file f1 is closed, the final display display information DL = “1” of the window W1 is acquired and stored in the final display state table T. As a result, it is possible to store in the final display state table T information specifying which display was the last displayed window for displaying the file f1.

<2-2. Window creation process>
<When a file name is specified>
FIG. 6 is a flowchart showing the processing operation when creating a window for displaying the file based on the designation of the file name. Unless otherwise specified, the following operations are performed under the control of the control unit 11.

  When it is determined that the user inputs an instruction to create a window for displaying the file based on the file name via the operation unit 19, the creation / end instruction receiving unit 101 receives the input operation (step S21).

  Subsequently, the display display selection unit 121 determines a display display for a newly created window. More specifically, this processing is performed as follows.

  First, it is determined whether or not final display information DL for the file name acquired in step S21 is stored in the final display state table T (step S22).

  If it is determined in step S22 that the final display information DL for the file name is stored, the display specified by the final display information DL is determined as the display for the window to be newly created (step S23). ). For example, when an instruction to create a window for displaying the file with the file name “document1.doc” is received in step S21, the display display selection unit 121 refers to the final display state table T illustrated in FIG. Then, the final display information DL = “1” is read, and the display device 21A specified by the final display information DL = “1” is determined as the display display device of the newly created window.

  If it is determined in step S22 that the final display display information DL for the file name is not stored, a predetermined display device determined in advance is determined as a display display for a newly created window (step S22). S24).

  Subsequently, the window creation unit 103 instructs the display controllers 17A and 17B to display a window for displaying the file having the file name acquired in step S1 in the display area of the display display determined in step S23 or step S24. (Step S25). In response to the instruction, the display controllers 17A and 17B display a window in a display area of a predetermined display.

  In other words, in the above processing, as shown in FIG. 9, the user who was editing the file f1 once closed the window W1, and then tried to open the window W2 displaying the same file f1 again. In this case, the window W2 is displayed in the display area of the same display device as the display device in which the file f1 was last displayed. In other words, since the window is displayed in the display area of the display device that displayed the window when the user interrupted the operation (that is, a screen on which the user can easily work), the user can change the created window to a screen on which the user can easily work. There is no need to perform the operation of moving. Therefore, the work can be resumed smoothly.

<When an address is specified>
FIG. 7 is a flowchart showing the processing operation when creating a window for displaying data existing on the network based on the designation of the address. Unless otherwise specified, the following operations are performed under the control of the control unit 11.

  If it is determined that the user inputs an instruction to create a window for displaying data existing on the network based on the designation of the address via the operation unit 19, the creation / end instruction receiving unit 101 inputs the input An operation is accepted (step S31).

  Subsequently, the display display selection unit 121 determines a display display for a newly created window. More specifically, this processing is performed as follows.

  First, it is determined whether or not final display information DL for the address acquired in step S31 is stored in the final display state table T (step S32).

  If it is determined in step S32 that the final display information DL for the address is stored, the display specified by the final display information DL is determined as the display for the window to be newly created (step S33). ). For example, when an instruction to create a window for displaying the web page at the address “http://www.A.co.jp” is received in step S31, the display display selection unit 121 displays the information shown in FIG. ) Is read, the final display information DL = “1” is read out, and the display device 21A that is specified by the final display information DL = “1” is newly created. Determined as a device.

  If it is determined in step S32 that the final display display information DL for the address is not stored, a predetermined display device determined in advance is determined as the display display of the window to be created (step S34). .

  Next, the window creation unit 103 instructs the display controllers 17A and 17B to display the window for displaying the web page at the address acquired in step S31 in the display area of the display display determined in step S33 or step S34. (Step S35). In response to the instruction, the display controllers 17A and 17B display a window in a display area of a predetermined display.

  That is, in the above processing, as shown in FIG. 9, after a user who has browsed a certain web page p1 closes the window W3, the user tries to open the window W4 displaying the web page p1 with the same address again. In this case, the window W4 is displayed within the display area of the same display device as the display device on which the web page p1 was last displayed (that is, a screen suitable for the user to browse the web page). Therefore, the user does not need to perform an operation of moving the created window to a screen suitable for browsing. Therefore, browsing of the web page can be resumed smoothly.

<When creating a child window>
FIG. 8 is a flowchart showing a processing operation when a child window is created based on a child window creation instruction based on the parent window created earlier. Unless otherwise specified, the following operations are performed under the control of the control unit 11.

  When it is determined that the user has input an instruction to create a child window based on the previously created parent window via the operation unit 19, the creation / end instruction receiving unit 101 receives the input operation. (Step S41).

  Next, the position detection unit 105 detects the display position of the parent window from which the child window is created, and outputs the display display information D of the parent window (step S42).

  Subsequently, the display display selection unit 121 determines that the display specified by the display display information D output in step S42 is the display display of the child window to be newly created (step S43). For example, when the display display information D “2” of the parent window is output in step S42, the display display selection unit 121 sets the display device 21B specified by the display display information D as the display display of the child window to be newly created. decide.

  Subsequently, the window creation unit 103 gives the display controllers 17A and 17B an instruction to display the designated child window in the display area of the display display determined in step S43 (step S44). In response to the instruction, the display controllers 17A and 17B display the child window in the display area of a predetermined display.

  That is, in the above processing, as shown in FIG. 10, when a child window Wb is created based on the parent window Wa created earlier, the child window Wb is the same as the display device on which the parent window Wa is displayed. It will be displayed in the display area of the display device. Therefore, the user can access the child window Wb without straddling the display screen area of each display device. That is, when accessing the created child window Wb, it is not necessary to move the mouse pointer greatly across the display, and work efficiency is improved.

<3. Modification>
[Modification 1]
In the above embodiment, in the final display state table T, the final display information DL is stored in association with information on the data displayed in the window (the file name of the file displayed in the window and the address of the web page). However, instead of (or in addition to) the final display information DL, information indicating the display position of the window when the window is closed (hereinafter referred to as “final display position information PL”) is stored. It is good also as a structure. FIG. 11A is a diagram showing a specific configuration example of the final display state table T1 in the first modification.

  In the case of the first modification, the processing unit corresponding to the final display state table management unit 106 in the above embodiment acquires the final position information PL from the position detection unit 105 and corresponds to the file name and the web page address. In addition, a process of storing in the final display state table T1 is performed. Alternatively, a processing unit that performs such processing is further provided.

This processing unit performs the following processing as processing corresponding to step S23 and step S33 in the above-described embodiment (or after the processing of steps S23 and S22). That is, when it is determined that the final position information PL for the file name and address for the newly created window is stored in the final display state table T1, the position indicated by the final position information PL is newly set. Determine the display position of the window to be created. For example, when a window for displaying a file with the file name “document1.doc” is created, the final display position information PL = “(10, 50)” with reference to the final display state table T1 shown in FIG. And the position specified by the final display position information PL is determined as the display position of the newly created window.

  In the first modification, when a user who has been editing a file once closes the window and then tries to open a window that displays the same file again, the file is displayed last in the window. It is displayed at the position where it was (that is, the position suitable for the user to work on the file). Therefore, the user does not need to perform an operation of moving the created window to a position suitable for work. Therefore, the work can be resumed smoothly.

  In addition, when a user tries to display a web page that the user has browsed before, the window is the position where the window displaying the web page was last displayed (that is, suitable for viewing the web page for the user). Displayed). Therefore, the user does not need to perform an operation of moving the created window to a position suitable for browsing. Therefore, browsing of the web page can be resumed smoothly.

[Modification 2]
In the first modification, the final display position information PL is stored in the final display state table T1. However, in addition to (or in place of) the final display position information PL, the window when closing the window is displayed. The information indicating the display size (hereinafter referred to as “final display size information SL”) may be stored. FIG. 11B is a diagram showing a specific configuration example of the final display state table T2 in the second modification.

  In the case of the second modification, the processing unit corresponding to the final display state table management unit 106 in the above-described embodiment acquires the final display size information SL from the position detection unit 105, and acquires the file name and the web page address. Corresponding storage processing is performed in the final display state table T2. Alternatively, a processing unit that performs such processing is further provided.

  The processing unit corresponding to the window display state determination unit 102 further includes a processing unit that determines the window size of a newly created window. This processing unit performs the following process after the process corresponding to step S23 or step S33 in the above embodiment. That is, when it is determined that the final display size information SL for the file name and address for the newly created window is stored in the final display state table T2, the display size indicated by the final display size information SL is changed. The display size of the newly created window is determined. For example, when a window for displaying the file with the file name “document1.doc” is created, the final display size information SL = “width = 30, height” is referred to with reference to the final display state table T2 shown in FIG. = 80 ”is read, and the window size indicated by the final display size information SL is determined as the display size of the newly created window.

  In the second modification, when a user who has been editing a file once closes the window and then tries to open a window displaying the same file again, the file is displayed last in the window. The window is displayed in the same size as the window size (that is, the window size that is easy for the user to work). Therefore, the user does not need to perform an operation of changing the created window to a size that is easy to work on, so the work can be resumed smoothly.

  In addition, when a user tries to display a web page that the user has browsed before, the window is the window size in which the window displaying the web page was last displayed (that is, the user browses the web page). The window size is suitable for the same size). Therefore, since the user does not need to perform an operation of changing the created window to a size suitable for browsing, browsing of the web page can be smoothly resumed.

[Modification 3]
In the above embodiment, if the final display state table T does not store the final display information DL about the file name or address of the data to be displayed in the window to be created, a predetermined predetermined value is stored. The display device is determined to be the display display of the window to be created (step S24 in FIG. 6 and step S34 in FIG. 7). However, instead of the processing in step S24 and step S34, the following treatment may be performed. Good.

  For example, if it is determined in step S22 that the final display information DL is not stored, is the final display information DL stored for the file name associated with the file name acquired in step S21 subsequently stored? Judge whether or not. The file names related to each other are, for example, file names indicating the same type of files or file names including the same keyword, and the user can freely set what file names are associated with each other. And

  When it is determined that the final display display information DL for the associated file name is stored, the display device specified by the final display display information DL is determined as the display display of the newly created window.

[Other variations]
In the above embodiment, in the final display state table T, the final display information DL is stored in association with the information related to the data displayed in the window, and as the information related to the data displayed in the window Although the file name of the file displayed in the window and the address of the web page are used, various other information can be used. For example, a window caption may be used.
