  The mobile phone 1 has a multitasking function that can execute a plurality of applications. The mobile phone 1 further has a function of simultaneously displaying a plurality of execution screens of the activated application on the display surface 3.

The screen control process is a process for the display processing unit 31 to change the arrangement of the execution screen of the application based on the detection processing unit 32 detecting an operation (screen changing operation) that satisfies a predetermined condition on the display surface 3. is there.

  FIG. 3A is a flowchart showing screen control processing according to the present embodiment. FIG. 4A and FIG. 4B are diagrams showing an example of transition of the screen displayed on the display surface 3 when the screen control process is executed. In the screen control process shown in FIG. 3, an application is started based on a predetermined operation by the user, and a plurality (two) of execution screens based on the application as shown in FIG. 4A are displayed on the display surface 3. When executed.

  Hereinafter, for the sake of brevity, an execution example of the screen control process when the execution screens of the two applications (A1, A2) are displayed adjacent to each other on the display surface 3 will be described. Although description is omitted, when three or more execution screens are displayed on the display surface 3, it is possible to execute the screen control process for the execution screens adjacent to each other with the boundary interposed therebetween.

When the execution of the screen control process shown in FIG. 3A is started, the display processing unit 31 executes an initial display process (S101). On the display surface 3, the display processing unit 31 displays the first execution screen 41 in the first region R1, and the second execution screen 42 in the second region R2 adjacent to the first region R1 with the boundary B interposed therebetween. indicate. The first execution screen 41 and the second execution screen 42 are execution screens of the activated applications A1 and A2, respectively. The first execution screen 41 and the second execution screen 42 are adjacent to each other across the boundary B.

  The display processing unit 31 displays an image showing the boundary B, such as an image of a line along the boundary B, on the display surface.

  The display processing unit 31 determines the position of the boundary B between the first region R1 and the second region R2 based on the parameter V. The parameter V indicates the Y coordinate of the boundary B, and is set to a predetermined initial value in advance prior to the initial display process.

  Here, the coordinates on the display surface 3 are determined by the X axis (horizontal direction) and the Y axis (vertical direction) shown in FIG. Each unit of the X-axis coordinate and the Y-axis coordinate is, for example, a pixel. The origin (0, 0) corresponds to the upper left corner of the display surface 3, and the coordinates corresponding to the position of the left end of the boundary B on the display surface 3 are (0, V).

  The display processing unit 31 defines a first region R1 and a second region R2 based on the boundary B. The first region R1 is a region whose Y coordinate is less than V. The second region R2 is a region whose Y coordinate is V or more.

  The parameter V is changed in accordance with the movement of the boundary B, and the first area R1 and the second area R2 change with the movement. The change that increases the parameter V corresponds to the downward movement of the boundary B (Y-axis positive direction). With the movement, the first region R1 is enlarged and the second region R2 is reduced. Conversely, a change that decreases the parameter V corresponds to a movement of the boundary B in the upward direction (Y-axis negative direction). With the movement, the first region R1 is reduced and the second region R2 is enlarged. The first region R1 and the second region R2 after the change are adjacent to each other across the region B after the movement.

  After the initial display process (S101), when the control unit 11 detects a touch operation on the display surface 3 based on the position signal from the operation input unit 14 (S102: YES), the detection processing unit 32 performs the detection process (S103). Execute.

  FIG. 3B is a flowchart showing the detection processing routine. The detection process routine shows the contents of the detection process in step S103. The detection process is a process for detecting a screen change operation. When the initial input position (start position) of the touch operation is on the boundary B, the detection processing unit 32 sets “1” in the flag F, assuming that the screen change operation is detected (S110), and the detection processing routine. Exit. If the initial input position of the touch operation is not on the boundary B, the detection processing unit 32 sets “0” to the flag F, assuming that the screen change operation is not detected (S110), and ends the detection processing routine.

  Here, the initial input position (start position) of the touch operation refers to the input position of the touch operation detected in step S102. If the Y coordinate of the initial input position is substantially equal to the parameter V, “1” is set in the flag F (F = 1, S110). The Y coordinate of the input position of the touch operation is acquired based on the position signal from the operation input unit 14. When the Y coordinate of the initial input position is not substantially equal to the parameter V, “0” is set in the flag F (F = 0, S111).

  In the screen control process, the detection process (S103) for setting the flag F is executed only once after the touch operation is started (S102: YES) to the end (S107: NO). For this reason, the flag F is not changed once it is set to “0” or “1” while a series of touch operations continues.

  If F = 0 (S104: NO), the process of step S107 is executed. In step S107, the control unit 11 executes processing for determining whether or not the touch operation is continued. If it is determined as NO in step S107, the determination process in step S104 is executed again. While the touch operation (F = 0) that is not regarded as a screen change operation continues, the processes in steps S104 and S107 are repeatedly executed, and the movement of the boundary B (S105) and the screen (first execution screen 41, second execution) described later are performed. The process for updating (S106) of screen 42) is not executed. That is, the position of the boundary B is fixed while the touch operation (F = 0) that is not detected as the screen change operation continues.

  When F = 1, that is, when a screen change operation is detected by the detection processing unit 32 (S104: YES), the display processing unit 31 executes the processes of steps S105 to S107.

  For example, as shown in FIG. 4A, when the user performs a touch operation on the display surface 3 (S102: YES) and the initial input position of the touch operation is on the boundary B (S109: YES). ), The flag F is set to “1” (S110 → S104: YES). In this case, the display processing unit 31 executes the processes of steps S105 to S107.

  The process in step S105 is a process for moving the boundary B up and down in response to an increase or decrease in the Y coordinate of the input position of the acquired touch operation. The increase and decrease of the Y coordinate of the input position of the touch operation correspond to the downward and upward movement of the boundary B, respectively.

  In step S0105, the display processing unit 31 sets the parameter V to the Y coordinate Y1 of the current input position of the touch operation. As described above, the boundary B is moved based on the set parameter V. In step S106, the display processing unit 31 updates the first execution screen 41 and the second execution screen 42 so as to match the first region R1 and the second region R2 that have changed as the boundary B moves.

  When the control unit 11 determines that the touch operation detected in step S102 is continuing (S107: YES), the display processing unit 31 executes the processes in steps S104 to S106 again. That is, the display processing unit 31 repeats the processes of steps S104 to S106 until it is determined NO in step S107 based on the end of the touch operation performed by the user (the finger is released from the display surface 3). Run.

  The update of the execution screen (41, 42) is, for example, an update by enlargement or reduction of an image according to a change in the size of the area (R1, R2) of the execution screen, a layout update, or the like. The execution screen may be updated so that further detailed information or summary information of the information displayed on the execution screen is displayed in response to the area being enlarged or reduced.

  As shown in FIG. 4A, when the input position of the touch operation moves from the initial input position P in the direction of the arrow pointing to the lower left, the Y coordinate Y1 of the input position gradually increases. Since the parameter V is set to the gradually increasing Y coordinate Y1 (S105), the boundary B is gradually moved downward. As the boundary B moves, the first region R1 and the second region R2 change so as to be adjacent at the moving boundary B. In the display processing unit 31, the first execution screen 41 and the second execution screen 42 are updated so as to adapt to the changing first region R1 and second region R2, respectively. While the current input position is detected by continuing the touch operation, the first execution screen 41 and the second execution screen 42 are continuously updated so as to be adjacent at the boundary B passing through the current input position.

After the input position of the touch operation is moved to a desired position by the user, when the current input position Q shown in FIG. 4 (a) is detected by the operation input unit 14, as shown in FIG. 4 (b), The parameter V is set to the Y coordinate Y1 of the current input position Q (S105). The boundary B is moved to the current input position Q. Then, the first execution screen 41 and the second execution screen 42 are displayed on the display surface 3 so as to be adjacent to each other with the boundary B after being moved.

  When the touch operation is not detected when the current input position Q is detected (S107: NO), the control unit 11 proceeds to the process of step S108 as described above. In step S108, the control unit 11 determines whether or not the application A1 or the application A2 is terminated. When the two applications A1 and A2 are not finished (S108: NO), the process of step S102 is executed to detect the touch operation on the display surface 3 again.

  When the application A1 or the application A2 is finished (S108: YES), the screen control process shown in FIG. 3A is finished. When one application (A1 or A2) has not ended, an execution screen (41 or 42) corresponding to the application is displayed on the entire display surface 3 after the screen control process ends. When both the applications A1 and A2 are finished, a predetermined screen (home screen or the like) is displayed on the display surface 3.

  FIG. 5A and FIG. 5B are diagrams showing an example of transition of the screen displayed on the display surface 3 when the screen control process is executed. In contrast to the touch operation described with reference to FIGS. 4A and 4B, when a touch operation such as a slide operation in which the Y coordinate of the input position decreases is detected, FIG. , (B), the boundary B is moved upward.

  For example, as shown in FIG. 5A, a touch operation in which the input position moves upward from the initial input position P to the current input position Q can be detected. In the case of FIG. 5A, since the initial input position P is on the boundary B, the detection processing unit 32 detects the touch operation as a screen change operation. As a result, the display processing unit 31 moves the boundary B to the current input position Q.

  As described above, according to the present embodiment, the boundary B is moved in the direction corresponding to the screen change operation by the user, and the region size is changed in accordance with the movement of the boundary B, respectively. The first execution screen 41 and the second execution screen 42 are updated so as to be adjacent to each other across the boundary B after the movement.

  The user can move the boundary B in the direction corresponding to the moving direction by moving the position of the finger touching the display surface 3 by the screen changing operation. For example, the user expands the display area of the desired execution screen, thereby improving the convenience of browsing and operating the execution screen. The touch operation as the screen change operation performed by the user does not require procedures such as opening the setting screen and selecting a desired item on the menu screen.

  Therefore, according to the present embodiment, when a plurality of execution screens based on the application are displayed on the display surface, the user can change the display area of the execution screen to a desired size.

  Furthermore, in the present embodiment, the screen change operation detected by the detection processing unit 32 is a touch operation that moves the input position, such as a slide operation or a flick operation. The direction in which the boundary B is moved corresponds to the direction of the component orthogonal to the boundary B of the input position movement. Therefore, the user can intuitively recognize the movement of the boundary B accompanying the touch operation.

Furthermore, in the present embodiment, when the initial input position of the touch operation, that is, the start position of the touch operation is on the boundary B, the touch operation is detected as the screen change operation. When the user wants to change the size of the display area of the execution screen, the user simply touches the boundary B displayed on the display surface 3 with his / her finger and moves the fingertip to move the first execution screen 41 and the second execution screen 42. Since the arrangement of can be changed, the operation is simple.

<Modification 1>
According to the configuration of the first modification example, when the input position of the touch operation moves from one area to the other area beyond the boundary B, the boundary B is moved in a direction corresponding to the touch operation.

  FIG. 6A is a flowchart showing the screen control process according to the present modification example. FIG. 6B is a flowchart showing the detection processing routine. The detection process routine shown in FIG. 3B shows the contents of the detection process in step S103 shown in FIG.

  In the flowchart of FIG. 6A, if NO is determined in step S107 (processing for determining the continuation state of the touch operation) in FIG. 3A, step S103 is executed instead of step S104. That is, in the above-described embodiment, the detection process is executed once for each touch operation. In the present modification, the detection process is repeatedly executed while the touch operation continues.

  As a result of repeatedly executing the detection process while the touch operation continues, as will be described later, the detection processing unit 32 detects the touch operation as a screen change operation while one touch operation is being performed. In some cases, the screen change operation is not detected.

  In the flowchart of FIG. 6B, the process of step S109 in FIG. 3B is replaced with the processes of steps S121 and S122.

  The detection processing routine (FIG. 6B) according to this modification will be described below.

  In step S121, the detection processing unit 32 determines whether or not the initial input position of the touch operation is in one of the first region R1 and the second region R2.

  When it is determined YES in step S121, the detection processing unit 32 determines whether or not the input position of the current touch operation is on the other region different from the one region. If the detection processing unit 32 determines YES in step S121, the detection processing unit 32 sets “1” to the flag F on the assumption that the user has performed a screen change operation (F = 1, S110). The detection processing routine ends.

  The processes in steps S121 and S122 are executed based on the magnitude relationship between the Y coordinate of the input position of the touch operation and the parameter V.

  When it is determined NO in step S121 or S122, the detection processing unit 32 sets “0” in the flag F (F = 0, S111), assuming that the screen change operation is not performed by the user, and ends the detection processing routine. To do.

  FIG. 7A to FIG. 7C are diagrams illustrating transition examples of screens displayed on the display surface 3 when the screen control process is executed. According to FIG. 7A, the initial input position P of the touch operation is in the first region R1. In the determination process of step S121, the detection processing unit 32 determines YES because the input position is in the first region R1, and therefore the determination process of step S122 is executed.

When the contact position of the user's finger on the display surface 3 remains at the initial input position P, the detection processing unit 32 assumes that the current input position (P) is not on the second region R2 (the other region). In step S122, NO is determined. At this time, the detection processing unit 32 does not detect a screen change operation (F = 0).

  Thereafter, when the current input position P1 shown in FIG. 7A is detected, the detection processing unit 32 performs the screen change operation because the current input position P1 is on the other area (S122: YES). Detect (F = 1, S110).

  In the screen control process, when it is detected that F = 1, the display processing unit 31 sets the parameter V to the Y coordinate Y1 of the current input position P1 of the touch operation (S105). As shown in FIG. 7B, the boundary B is moved to the current input position P1. When the touch operation is detected as the screen change operation, the boundary B is continuously moved following the current input position. As the boundary B moves, the execution screen of the application A1 is enlarged and the execution screen of the application A2 is reduced.

  The current input position P1 can be moved to a new current input position Q shown in FIG. In this case, the current input position Q is in the first area R1 (one area) to which the initial input position P belongs. In this case, the boundary B remains at the position shown in FIG. 7B based on the screen control process and the detection process routine.

  That is, since the current input position Q is not on the other region (second region R2) (S122: NO), the detection processing unit 32 does not detect the screen change operation (F = 0). In this case, since the process for setting the parameter V is not executed, the parameter V is maintained at the value set in the state shown in FIG. 7B, as shown in FIG. 7C. Therefore, the boundary B remains at the position shown in FIG.

  As shown in FIGS. 7A to 7C, the user can move the boundary B so as to push it down from the first region R1 side.

  The user can reduce the first area R1 by performing a touch operation so that the second area R2 is set to the initial touch position and moving the boundary B so as to push up from the second area R side.

  That is, the screen control process also detects a screen change operation for moving the boundary B upward (Y-axis negative direction). When an operation that moves in the direction opposite to the direction of the arrow shown in FIG. 7A, that is, a touch operation in which the initial input position is P1 and the current input position is P, is detected. 32 detects a screen change operation (F = 1). In this case, the boundary B is moved upward from a predetermined position where the Y coordinate is V to the current input position P.

  As described above, according to this modified example, when a touch operation that continues from the first region R1 to the second region R2 is performed on the display surface 3, that is, the touch operation starts from one region, and When the detection processing unit 32 continues to enter the other region beyond the boundary B, the detection processing unit 32 detects the touch operation as a screen change operation. When one region is the first region R1, the other region is the second region R2. When one region is the second region R2, the other region is the first region R1.

  By detecting the screen changing operation according to this modification example, the user can move the boundary B so as to push it out from the inside of one region.

The configuration of this modified example can be combined with the configuration of the above embodiment. In this case, when the initial input position of the touch operation is on the boundary B, the screen control process and the detection process routine described in the above embodiment are executed, and further, the initial input position of the touch operation is the first input position. When in the area R1 or the second area R2, the screen control process and the detection process routine described in the present modification are executed.

<Modification 2>
FIG. 8A is a flowchart showing a screen control process according to this modification. FIG. 8B and FIG. 8C are diagrams showing a transition example of the screen displayed on the display surface 3 when the screen control process is executed according to the present modification example.

  The screen control process in the present modification is substantially the same as the screen control process in the first modification. However, the screen control process in the present modified example is different from the screen control process in the modified example 1 in that the process in step S105 is replaced with the process in step S131 as shown in FIG.

  In the process of step S131, the operation when the process is executed for the first time with respect to the continuing touch operation is different from the operation of the process of step S105, and the operation of the process after the second time is the same as the process of step S105. .

  When the process of step S131 is executed for the first time with respect to the touch operation currently being performed, the display processing unit 31 sets the parameter V to V + ΔV or V−ΔV. Here, ΔV is a positive predetermined value. The display processing unit 31 determines the sign (+ or −) related to the predetermined value ΔV so that the boundary B moves in a direction suitable for the touch operation.

  That is, the input position of the touch operation is changed from the first area R1 (initial input position P) as shown in FIG. 8A to the boundary B (current input position P1) as shown in FIG. 8B. When moving up for the first time, the display processing unit 31 sets V = V + ΔV. As the value of the parameter V increases by ΔV, the boundary B is discontinuously moved downward by a predetermined distance corresponding to the predetermined value ΔV as shown in FIG. Along with this, the execution screen of the application A1 is enlarged according to the moving distance of the boundary B.

  Similarly, when the input position of the touch operation moves from the second region R2 to the boundary B for the first time, the display processing unit 31 sets V = V−ΔV. In this case, the boundary B is discontinuously moved upward by a predetermined distance corresponding to the predetermined value ΔV.

  In the continuing touch operation, the process of step S131 may be executed after the second time. In this case, when the touch operation is detected as the screen change operation, the display processing unit 31 continuously moves the boundary B so as to follow the input position of the touch operation, as in the first modification.

  As described above, also in the present modification example, when the touch operation starts from one area and continues to enter the other area R2 beyond the boundary B, the detection processing unit 32 performs the touch operation on the screen. Detect as change operation. In the continuing touch operation, when the input position of the touch operation is positioned on the boundary B for the first time, the boundary B is moved by a predetermined distance in the direction of the touch operation detected as the screen change operation. The user can move the boundary B by a predetermined distance in a direction corresponding to the direction of the screen change operation without performing an operation of precisely designating the movement destination of the boundary B. Therefore, the operation is simplified.

  When the user desires to further modify the position of the boundary B after the discontinuous movement of the boundary B, the boundary B is continuously moved in the same manner as in the first modification by continuing the touch operation. Can do.

  The setting for increasing or decreasing the parameter V by ΔV in step S131 may be performed not only when step S131 is executed for the first time but also in the first N times (N is a predetermined positive integer).

  The configuration of this modified example can be combined with the configuration of the above embodiment.

<Modification 3>
In this modification example, when the user performs a touch operation that enlarges or reduces the area in the display area (execution screen) that is to be enlarged or reduced, the screen change operation is detected, and the touch operation is performed. The boundary B is moved in a direction corresponding to the direction.

  FIG. 9A is a flowchart showing screen control processing according to the present embodiment, according to this modification. FIG. 9B is a flowchart showing a detection processing routine according to this modification.

  In the flowchart shown in FIG. 9A, the process in step S141 is inserted after step S104 in the flowchart shown in FIG. 3A, and the process in step S105 is replaced with the process in step S142. In the flowchart shown in FIG. 9B, the process in step S109 in the flowchart shown in FIG. 3B is replaced with the process in step S143.

  The detection processing unit 32 detects the screen change operation when the initial input position of the touch operation is on one of the first region R1 and the second region R2 in the detection processing routine (FIG. 9B). (F = 1).

  FIGS. 10A to 10C are diagrams illustrating an example of transition of the screen displayed on the display surface 3 when the screen control process is executed according to this modification example.

  When the initial input position P of the touch operation (FIG. 10A) is detected, the detection processing unit 32 displays the touch operation on the screen because the input position is on the first region R1 (one region). The change operation is detected and F is set to “1” (S110).

  When F = 1 (S104: YES), the display processing unit 31 acquires the internal ratio α based on the initial input position P in step S141.

  Here, the internal ratio α indicates the internal ratio when the length of the first region R1 that is the target of the touch operation in the direction orthogonal to the boundary B is internally divided by the initial input position. Specifically, when the Y coordinate of the initial input position of the touch operation is Y0, the internal ratio α is given by the equation α = (V−Y0) / Y0. The display processing unit 31 acquires the internal division ratio α by executing a calculation process based on the formula.

  Since the internal ratio α is a value determined based on the initial input position P, the process in step S141 is performed while the touch operation continues after step S141 is executed once (S107: YES). Skipped.

  Unlike the example of FIG. 10A, when the initial input position P is on the second region R2, the internal ratio α is given by the equation α = (Y0−V) / (H−Y0). . Here, H represents the length in the orthogonal direction of the boundary B between the first region R1 and the second region R2.

After acquiring the internal ratio α based on the initial input position P (S141), the display processing unit 31 sets the parameter so that the internal ratio based on the current input position of the touch operation matches the internal ratio α. Set V.

  For example, the input position of the touch operation moves in the direction indicated by the arrow in FIG. 10A, and the Y coordinate Y1 of the current input position P1 as shown in FIG. 10B can be detected. In this case, the display processing unit 31 sets the parameter V so that the internal ratio (V−Y1) / Y1 based on the current input position P1 matches α. That is, the parameter V is given by the equation V = (1 + α) × Y1. The display processing unit 31 sets the parameter V by executing arithmetic processing based on the formula.

  As indicated by the arrow in FIG. 10A, when the input position of the touch operation moves downward, the Y coordinate of the input position increases (Y1> Y0), so the parameter V increases based on the above equation. It is set as follows.

  Since the display processing unit 31 moves the boundary B so as to maintain the internal ratio α, for example, when the initial input position of the touch operation is the center of the first region R1 in the Y-axis direction, the current input The boundary B is moved so that the position is always located at the center of the first region R1 after the change. As another example, when the initial input position of the touch operation is on the boundary B, the boundary B is moved to the current input position as in the above embodiment.

  When the input position of the touch operation moves upward as shown by an arrow in FIG. 10B, the Y coordinate Y2 of the current input position P2 of the touch operation as shown in FIG. 10C can be acquired. As described above, the display processing unit 31 sets the parameter V so that the internal ratio (V−Y2) / Y2 based on the current input position matches the internal ratio α (S142). In this case, the parameter V is set to decrease. The boundary B moves upward so as to maintain the internal ratio α.

  As described above, according to this modified example, the boundary B is moved so as to maintain the internal ratio based on the initial input position. With this configuration, when the user first touches one area (the first area R1 or the second area), the relative input position in the one area is fixed. Even if the user does not touch the boundary B, the user can move the boundary B by performing a touch operation in a desired area (execution screen), which is convenient.

<Modification 4>
FIG. 11 is a block diagram showing the overall configuration of a mobile phone according to this modification. In the present modification example, the control unit 11 further includes a scroll processing unit 33 (described later).

  FIG. 12A is a flowchart showing screen control processing according to the present embodiment, according to the present modification example. FIG. 12B is a flowchart showing a detection processing routine according to this modification.

  In the flowchart shown in FIG. 12A, the process in step S102 in the flowchart shown in FIG. 3A is deleted, and the process in step S105 is replaced with the process in step S151. In the flowchart shown in FIG. 12B, the processing in step S109 in the flowchart shown in FIG. 3B is replaced with the processing in steps S512 to S155.

  The screen control process according to this modification is executed when the execution screen (41, 42) of the application A1 or application A2 is displayed on the display surface 3 so as to be able to accept a predetermined scroll operation. The predetermined scroll operation is an operation for scrolling and displaying the execution screen on the target execution screen. The predetermined scroll operation is, for example, a slide operation or a flick operation in a scroll display direction.

  In the following, for the sake of simplicity, the first execution screen 41 of the application A1 accepts a predetermined scroll operation (for example, a slide operation in the direction of the arrow shown in FIG. 13A) as shown in FIG. The screen control process when it is displayed in the first region R1 as possible is described. However, the screen control process can also be applied to the second execution screen 42 of the application A2.

  Based on the execution of the application A1, the scroll processing unit 33 detects a vertical slide operation or the like as a scroll operation for scroll display. The scroll processing unit 33 scrolls and displays the first execution screen 41 in the direction (vertical direction) corresponding to the detected scroll operation based on the execution of the application A1.

  In the example used for explanation in this modified example, the execution screen is scroll-displayed in the vertical direction. The screen control process of the present modification example can be appropriately executed regardless of the scrolling direction, such as scroll display in the left-right direction or the licking direction.

  In FIG. 13A, a scroll bar 43 is displayed at the lower right on the first execution screen 41. The position in the vertical direction of the scroll bar 43 indicates the position of the first execution screen 41 in the content that can be displayed by scroll display. As indicated by the scroll bar 43 being displayed at the bottom of the first region R1, the first execution screen 41 is in a state where scroll display has been completed. A configuration in which the scroll bar 43 is not displayed may be adopted.

  Here, the state where the scroll display is completed means a state where the uppermost part or the lowermost part of the entire image to be displayed by executing the application is displayed as the first execution screen 41 in the first region R1. say. For example, in the execution screen displayed during the execution of the application of the web browser, the state where the uppermost part or the lowermost part of the content related to the execution screen is displayed is a state where the scroll display is completed.

  When a scroll operation as shown in FIG. 13A is detected, the first execution screen 41 is in a state where the scroll display has been completed. The unit 33 does not execute scroll display. In the case of this example, the direction of the scroll operation that is not accepted because the scroll display has been completed (hereinafter simply referred to as “direction in which scroll display cannot be performed”) is the upward direction.

  A detection processing routine according to this modification will be described.

  In step S152, the detection processing unit 32 determines YES when the first execution screen 41 is in a state where the scroll display has been completed.

  In step S153, the detection processing unit 32 determines YES when a scroll operation is detected in the direction in which the first region R1 cannot be scroll-displayed.

  In step S154, the detection processing unit 32 determines YES when a scroll operation in a direction in which scroll display cannot be performed as determined in step S153 is repeated under a predetermined condition (described later).

When it is determined YES in steps S152 to S153, the detection processing unit 32 detects the scroll operation as a screen change operation (F = 1, S110). If the detection processing unit 32 determines NO in any of steps S152 to S153, it does not detect a screen change operation (F = 0, S111).

  The predetermined condition regarding the scroll operation in the direction in which the scroll display cannot be performed is, for example, a condition regarding the frequency of the scroll operation in the direction in which the scroll display cannot be performed. More specifically, for example, the predetermined condition is that the slide operation is performed a predetermined number of times (for example, several times) or more within a predetermined time (for example, about several seconds).

  When a screen change operation is detected (F = 1), the display processing unit 32 sets the parameter V to V + ΔW on the assumption that the user has made a screen change operation. ΔW is a predetermined positive threshold. As a result of setting the parameter V to V + ΔW, the boundary B is moved downward by ΔW as shown in FIG. The execution screen 41 of the application A1 is enlarged by ΔW.

  As described above, according to the present modification example, after the scroll display of the first execution screen 41 is completed, the detection processing unit 32 further performs a scroll operation in a direction in which the scroll display cannot be performed under a predetermined condition. The scroll operation is detected as a screen change operation. For example, when a scroll operation in a direction in which scroll display cannot be performed more than a predetermined number of times within a predetermined time is detected, the detection processing unit 32 detects a screen change operation.

  When the screen change operation is detected, the boundary B is automatically moved in the direction of enlarging the first region R1.

  Since the first area R1 is enlarged when the display contents cannot be browsed comfortably, the user can comfortably browse the first execution screen 41 displayed in the first area R1.

<Modification 5>
FIGS. 14A to 14C are diagrams illustrating transition examples of screens displayed on the display surface 3 at the time of execution of the screen control process according to the present modification example.

  Before the boundary B is moved, a confirmation process for confirming execution of the movement of the boundary B to the user may be further added to the screen control process of the modification example 4 described above.

  For example, as in FIG. 13A described in the modification example 4, when a scroll operation that is regarded as an image change operation is detected by the detection processing unit 32, as shown in FIG. Displays to emphasize the boundary B.

  The display for emphasizing the boundary B is a display based on various types of image processing that has a visual effect of emphasizing the boundary B. For example, a display that looks as if the boundary B is shining, and a display that blinks the boundary B And a display for changing the thickness, color, and pattern of the boundary B.

  The detection processing unit 32 waits for an input (touch operation) to the emphasized boundary B. When the detection processing unit 32 detects an input (touch operation) to the emphasized boundary B as shown in FIG. 14B, the display processing unit 31 displays the boundary B as described above as shown in FIG. Move in the same manner as in the third modification.

  When the input for the boundary B is not detected for a predetermined time or longer after the display for emphasizing the boundary B is started, the detection processing unit 32 cancels the emphasis display and stops waiting for the input to the boundary B.

Even when the detection processing unit 32 detects a touch operation at a position other than the boundary B, the highlight table is canceled.

  As described above, according to the fifth modification example, when the scroll operation as the image change operation is detected by the detection processing unit 32, the confirmation process regarding the movement of the boundary B is executed. The confirmation process is a display process for emphasizing the boundary B. Based on the detection processing unit 32 detecting the input to the emphasized boundary B, the display processing unit 31 moves the boundary B to the second region R2 side by a predetermined distance (ΔW).

  The user highlights the boundary B for performing the movement of the boundary B without being obstructed by browsing the execution screens (the first execution screen 41 and the second execution screen 42) displayed on the display surface 3. Can be recognized. When the user desires, the first area R1 that is the display area of the first execution screen 41 can be enlarged by performing a touch operation on the boundary B.

However, the display processing unit 31 may be configured not to update the first execution screen 41 and the second execution screen 42 while the touch operation is detected as the screen change operation by the detection processing unit 32. For example, after the end of the touch operation, the detection processing unit 32 is adapted to each of the first region R1 and the second region R2 that have changed along with the movement of the boundary B based on the detection of the touch operation as a screen change operation. The first execution screen 41 and the second execution screen 42 may be updated. In this case, while the touch operation is detected as the screen change operation, the display processing unit 31 displays an image such as a line indicating the boundary B for notifying the position of the moving boundary B on the display surface 3. May be.

  In the embodiment and Modification Examples 1 to 5, as an example, the first region R1 and the second region R2 are allocated on the display surface 3 so that the boundary B faces the horizontal direction (X-axis direction). The first region R1 and the second region R2 are not limited to the horizontal direction, but are adjacent to each other with a boundary in the vertical direction (Y-axis direction) as shown in FIGS. It may be allocated on the display surface 3 so as to be adjacent to each other with the boundary B facing the direction. For example, as shown in FIGS. 15A and 15B, the mobile phone 1 may be used in either a vertical orientation or a horizontal orientation.

  In the said embodiment and the modification examples 1-5, the case where 1st area | region R1 and 2nd area | region R2 covered the display surface 3 whole was demonstrated as an example. However, the configurations of the above-described embodiment and Modifications 1 to 5 are also applicable when the first region R1 and the second region R2 cover a part of the display surface 3 as shown in FIG.

  In the said embodiment and the modification examples 1-5, the case where two execution screens, the 1st execution screen 41 and the 2nd execution screen 42, were displayed on the display surface 3 as an example was demonstrated. However, even when three or more execution screens are displayed on the display surface 3, the configurations of the above-described embodiment and Modifications 1 to 5 are applicable.

The configurations of the above-described embodiment and modification examples 1 to 5 can also be applied when the display surface 3 is configured by two or more individual display surfaces. For example, as shown to Fig.17 (a), the display surface 3 is good also as what is comprised from the two display surfaces 3a and 3b arrange | positioned so that it may adjoin substantially. Usually, when the display surface 3 is configured to be seen integrally from the two display surfaces 3a and 3b,
As shown in FIG. 17A, the execution screens 41 and 42 of the two applications A1 and A2 are displayed on the display surfaces 3a and 3b, respectively. That is, the first region R1 and the second region R2 are allocated to the display surfaces 3a and 3b, respectively. In this case, the boundary B between the first region R1 and the second region R2 is an adjacent side on each display surface 3a, 3b. For example, when it is detected that the input position of the touch operation moves from the initial input position P shown in FIG. 17A to the current input position Q, by executing the screen control process according to the above embodiment, As shown in FIG. 17B, the boundary B is moved to the current input position Q, and the size of the execution screens of the two applications A1 and A2 is changed as the boundary B moves. The screen control process according to the first to fifth modified examples is not limited to the above embodiment, and may be applied.

  In the configuration of FIGS. 17A and 17B, the execution screens 41 and 42 may be arranged in the integrally formed cabinet 2, or as shown in FIGS. 18A and 18B. You may distribute | arrange to each separate cabinet 2a, 2b. 18 (a) and 18 (b), the cabinet 2 of the mobile phone 1 includes a first cabinet 2a and a second cabinet 2b, and a display surface 3 is arranged in each cabinet 2a and 2b. It has 1 display surface 3a and 2nd display surface 3b. The cellular phone 1 includes a closed state in which the first cabinet 2a is stacked on the second cabinet 2b as shown in FIG. 18 (a), and the first cabinet 2a and the second cabinet as shown in FIG. 18 (b). The structure which can switch between the state where 2b was arranged side by side is taken. In the open state, the two display surfaces 3 a and 3 b are substantially flush with each other to form an integral display surface 3. As described with reference to FIGS. 17A and 17B, the boundary B is moved based on the screen control process, and the applications A1 and A2 displayed on the display surface 3 (3a and 3b) are executed. The sizes of the screens 41 and 42 are changed.

  The screen change operation is not limited to the operation described in the above embodiment and the first to fifth modification examples, and may be various operations. For example, an operation (long touch) that touches the boundary B for a predetermined time (for example, about several hundred milliseconds to several seconds) or longer may be detected as a screen change operation by the detection processing unit 32. According to this configuration, it is possible to avoid contention between the screen change operation and other touch operations such as an operation for scrolling the screen. In addition, erroneous detection of the screen change operation by the detection processing unit 32 is suppressed.

  In the above embodiment, the present invention is applied to a smartphone-type mobile phone. However, the present invention is not limited to this, and the present invention may be applied to other types of mobile phones such as a straight type, a folding type, and a sliding type.
