  The handwritten character input screen passes the character code generated based on the handwritten locus to the generation processing of another screen. For example, characters are displayed in the character input field by passing the data to the process for generating the editor screen.

  Next, the display area of each display will be described. FIG. 4 shows an example of the display area in the up and down direction. The upper rectangle indicates the display area of the first display 221 a of the first touch panel 101. In this example, the position in the display area of the first display 221a is specified by the coordinates. The coordinates (X1, Y1) indicate the upper left end point in the display area of the first display 221a. The coordinates (X2, Y1) indicate the upper right end point in the display area of the first display 221a. The coordinates (X1, Y2) indicate the lower left end point in the display area of the first display 221a. The coordinates (X2, Y2) indicate the lower right end point in the display area of the first display 221a.

  The lower rectangle indicates the display area of the second display 221b of the second touch panel 103. Similar to the upper rectangle, the position in the display area of the second display 221b is specified by coordinates. The coordinates (X3, Y3) indicate the upper left end point in the display area of the second display 221b.

The coordinates (X3, Y4) indicate the lower left end point in the display area of the second display 221b. The coordinates (X4, Y4) indicate the lower right end point in the display area of the second display 221b.

  Here, an example is shown in which the positions in the display area of the first display 221a and the second display 221b are specified by coordinates, but the display areas of the first display 221a and the second display 221b are determined by combinations of touch panel identifiers and coordinates. You may make it pinpoint the position in. This is the end of the description of the display area of each display.

  When a screen is displayed in the display area, the operating system manages the screen being displayed. Next, screen management data provided by the operating system will be described.

  FIG. 5 shows an example of screen management data in the first embodiment. The screen management data has a record for each screen being displayed. Further, the record includes a field indicating an area displaying the screen being displayed. The first record in FIG. 5 indicates that the outgoing mail editing screen is displayed in a rectangle specified by the upper left end point (X1, Y1) and the lower right end point (X2, Y2) in the display area of the first display 221a. Show. The second record in FIG. 5 indicates that the soft keyboard screen is displayed in a rectangle specified by the upper left end point (X3, Y3) and the lower right end point (X4, Y4) in the display area of the second display 221b. ing.

  In this example, the soft keyboard screen is called to assist data input to the outgoing mail editing screen displayed on the entire surface of the first display 221a, and the called soft keyboard screen is displayed on the entire surface of the second display 221b. This corresponds to the screen management data in the current situation. This is the end of the description of the screen management data provided by the operating system.

  Next, the mode according to the first embodiment will be described with reference to FIG. In the first embodiment, the power saving modes A to D are provided in addition to the normal mode. FIG. 6 is based on the situation in which the outgoing mail editing screen is displayed on the first display 221a and the soft keyboard screen is displayed on the second display 221b as in FIG. Each record indicates the state of the first display 221a, the state of the first touch pad 223a, the state of the second display 221b, and the state of the second touch pad 223b in each mode.

  As shown in the first record, in the normal mode, both the first display 221a and the second display 221b display each screen with normal luminance, and both the first touch pad 223a and the second touch pad 223b operate.

  As shown in the second record, in the power saving mode A, the second display 221b displaying the soft keyboard screen has a low luminance. However, the first display 221a remains at the normal luminance. Both the first touch pad 223a and the second touch pad 223b operate.

  As shown in the third record, in the power saving mode B, the second display 221b and the second touch pad 223b are suspended. The first display 221a remains at normal brightness, and the first touch pad 223a also operates.

  As shown in the fourth record, in the power saving mode C, the second display 221b and the second touch pad 223b remain at rest. The first display 221a displaying the outgoing mail editing screen has a low brightness. The first touch pad 223a operates.

  As shown in the fifth record, in the power saving mode D, both the first display 221a and the first touch pad 223a are suspended. The second display 221b and the second touch pad 223b remain at rest.

  As described above, in the power saving mode A, the data input screen first has a low luminance, and in the power saving mode B, the display of the data input screen disappears, and touch detection on the screen is also paused. Further, in the power saving mode C, the display of the screen other than the data input screen becomes low brightness, and in the power saving mode D, the display of the screen other than the data input screen disappears, and the touch detection on the screen is also stopped.

  When time elapses without being operated by the user, transition is made from the normal mode to the power saving mode A, the power saving mode B, the power saving mode C, and further the power saving mode D.

  Mode transition over time will be described. Hereinafter, for ease of understanding, the timer A and the timer B will be described separately for convenience. The timer A measures a period during which the normal mode has not been operated since the start of the normal mode. The timer B measures a period during which the power saving mode B is not operated from the start time. However, since the timer A and the timer B do not operate at the same time, they may be realized by one timer.

  FIG. 7 shows a time chart by the timer A. When each screen is displayed in the normal mode, the timer A starts operating. Then, when the period in which the operation is not performed in the normal mode exceeds the time length T1, the power saving mode A is started. Further, when the time period during which the operation is not performed further exceeds the time length T2, the mode is shifted to the power saving mode B. When shifting to the labor saving mode B, the measurement by the timer A is finished. If a predetermined operation is performed before the time period during which the operation is not performed exceeds the time length T2, the timer A is reset and returns to the initial state of the normal mode.

  FIG. 8 shows a time chart by the timer B. When shifting to the labor saving mode B, the timer B starts operating. When the period in which the power saving mode B is not operated exceeds the time length T3, the power saving mode C is entered. Further, when the time period during which the operation is not performed further exceeds the time length T4, the power saving mode D is entered. When the labor saving mode D is entered, the measurement by the timer B ends. If a predetermined operation is performed before the time period during which the operation is not performed exceeds the time length T4, the timer B may be reset to return to the initial state of the power saving mode B. In addition, if another predetermined operation is performed before the time period during which the operation is not performed exceeds the time length T4, the timer B ends and the normal mode may return to the initial state.

  In addition to the case where the above time elapses, the mode may be changed by a predetermined operation. The predetermined operation corresponds to a return instruction described below. FIG. 9 shows an example of mode transition. FIG. 9 shows a transition by a return instruction other than the passage of time.

  As described in FIG. 7, when the measurement period by the timer A exceeds the time length T1, the normal mode is shifted to the labor saving mode A.

  When the operation of the return instruction A is received in the labor saving mode A, the mobile terminal device 100 returns to the normal mode. The return instruction A is performed by, for example, a touch operation on the touch pad corresponding to the display with low brightness. That is, by touching the surface of the display having the low luminance, the display of the display having the low luminance returns to the normal luminance.

  For example, in the state of the labor saving mode A shown in the second record of FIG. 6, the soft keyboard screen returns to the display state with the normal luminance by touching the soft keyboard screen having the low luminance. Note that the return instruction A may be performed by an operation other than the touch operation described above.

  As described in FIG. 7, when the measurement period by the timer A exceeds the time length T2, the power saving mode A is shifted to the power saving mode B.

  When the operation of the return instruction B is received in the labor saving mode B, the mobile terminal device 100 returns to the normal mode. The return instruction B is performed, for example, by pressing the key 105. That is, when the key 105 is pressed, the disappeared display is displayed again with the normal brightness. Accordingly, the operation of the touch pad corresponding to the redisplayed display is resumed.

  For example, as shown in the third record of FIG. 6, when the key is pressed in the power saving mode B in which the display of the soft keyboard screen disappears, the soft keyboard screen returns to the normal brightness display state and touch operation is also accepted. Be able to. Note that the return instruction B may be performed by an operation other than the key pressing operation described above.

  As described with reference to FIG. 8, when the measurement period by the timer B exceeds the time length T3, the power saving mode B shifts to the power saving mode C.

  When the operation of the return instruction C is received in the labor saving mode C, the mobile terminal device 100 returns to the normal mode. The return instruction C is performed, for example, by pressing the key 105. That is, when the key 105 is pressed, the disappeared display is displayed again with the normal brightness. Accordingly, the operation of the touch pad corresponding to the redisplayed display is resumed. In addition, the display on the display having the low luminance returns to the normal luminance.

  For example, as shown in the fourth record of FIG. 6, the soft keyboard screen is turned off by pressing the key in the power saving mode C in which the display of the soft keyboard screen disappears and the outgoing mail editing screen is displayed with low brightness. The display state is returned to the normal luminance, and a touch operation can be accepted. Further, the sent mail editing screen also returns to the display state with the normal luminance. Note that the return instruction C may be performed by an operation other than the key pressing operation described above.

  When the operation of the return instruction D is received in the power saving mode C, the mobile terminal device 100 returns to the power saving mode B. The return instruction D is performed by, for example, a touch operation on the touch pad corresponding to the display having a low luminance. That is, it operates so as to return to the normal luminance by touching the surface of the display having the low luminance. However, the paused display and touchpad remain the same.

  For example, in the state of the labor saving mode C shown in the fourth record in FIG. 6, the outgoing mail editing screen returns to the normal luminance display state by touching the outgoing mail editing screen that has become low in luminance. However, the soft keyboard screen remains off and no touch operation is accepted. Note that the return instruction D may be performed by an operation other than the touch operation described above.

  As described with reference to FIG. 8, when the measurement period by the timer B exceeds the time length T4, the power saving mode C is shifted to the power saving mode D.

  When the operation of the return instruction F is received in the labor saving mode D, the mobile terminal device 100 returns to the normal mode. The return instruction F is performed by, for example, pressing the key 105. That is, when the key 105 is pressed, both the disappeared displays are redisplayed at the normal brightness. Along with this, the operation of both touchpads resumes.

  For example, when the key 105 is pressed in the power saving mode D shown in the fifth record of FIG. 6, the sent mail editing screen and the soft keyboard screen return to the display state with the normal luminance. Also, touch operations on the outgoing mail editing screen and the soft keyboard screen can be accepted. Note that the return instruction F may be performed by an operation other than the key pressing operation described above. This is the end of the description of mode transition.

  FIG. 10 shows an example of a sequence according to the first embodiment. The mobile terminal device 100 includes an operating system 1101, a screen control unit 1103, and a mailer 1105. The mailer 1105 is an example of an application unit realized by an application program.

  The operating system 1101 mediates display of a screen specified by the application unit in response to a request from the application unit. Furthermore, the operating system 1101 displays a soft keyboard screen in response to a request from the application unit, and performs processing for receiving data such as a character code, a numeric code, or a control code. The accepted code is passed to the application section.

  The screen control unit 1103 controls the first display 221a, the first touch pad 223a, the second display 221b, and the second touch pad 223b according to the mode transition described above.

  The mailer 1105 performs processing such as mail generation, mail transmission, mail reception, mail list display, and mail browsing display. In this example, the mailer 1105 generates outgoing mail editing screen data and displays the outgoing mail editing screen via the operating system 1101.

  Hereinafter, the sequence will be described. The mailer 1105 first generates outgoing mail editing screen data, and requests the operating system 1101 to display the outgoing mail editing screen (S1001). The designation screen display request sent from the mailer 1105 to the operating system 1101 may include transmission mail editing screen data and information for specifying the display area. The information for specifying the outgoing mail edit screen data is, for example, an identifier of a buffer that stores the outgoing mail edit screen data. The information for specifying the display area is, for example, coordinates indicating the starting point.

  The operating system 1101 displays the requested designation screen (S1003). In this example, the transmitted mail editing screen is displayed on the first display 221a.

  The mailer 1105 requests the operating system 1101 to display a soft keyboard screen (S1005). The operating system 1101 displays a soft keyboard screen on the second display 221b (S1007).

  The screen control unit 1103 acquires screen management data from the operating system 1101 (S1009).

  As described above, when the predetermined period elapses, the screen control unit 1103 instructs the operating system 1101 to change the brightness so that the brightness of the second display 221b is lowered (S1011).

  Further, when a predetermined period elapses, the screen control unit 1103 instructs the operating system 1101 to pause the second display 221b and further pause the second touchpad 223b (S1013).

  Further, when a predetermined period elapses, the screen control unit 1103 instructs the operating system 1101 to change the luminance so that the luminance of the first display 221a is lowered (S1015).

  Further, when a predetermined period elapses, the screen control unit 1103 instructs the operating system 1101 to pause the first display 221a and further pause the first touch pad 223a (S1017). This is the end of the description of the sequence.

  FIG. 11 shows a module configuration example of the mobile terminal device 100 according to the first embodiment. The screen control unit 1103 includes an acquisition unit 1111, a screen management data storage unit 1113, a specification unit 1115, a data input screen list storage unit 1117, a determination unit 1119, a timer 1121, a reduction unit 1123, a return unit 1125, and a pause unit 1127. ing.

  The acquisition unit 1111 acquires management data (for example, screen management data) from the operating system 1101. The screen management data storage unit 1113 stores screen management data. The specifying unit 1115 specifies the touch panel displaying the data input screen. The data input screen list storage unit 1117 stores the data input screen list shown in FIG. The determination unit 1119 performs determination related to mode transition. The timer 1121 measures elapsed time. The reduction unit 1123 instructs to change the luminance for reducing the luminance of the first display 221a or the second display 221b. The return unit 1125 instructs to change the luminance for returning the luminance of the first display 221a or the second display 221b. Further, the return unit 1125 gives an instruction to return the paused first display 221a and the first touch pad 223a, or an instruction to return the paused second display 221b and the second touch pad 223b. The pause unit 1127 gives an instruction to pause the first display 221a and the first touch pad 223a or an instruction to pause the second display 221b and the second touch pad 223b.

  FIG. 12 shows an example of a main processing flow by the screen control unit 1103 according to the first embodiment. The acquisition unit 1111 acquires screen management data from the operating system 1101, and stores the acquired screen management data in the screen management data storage unit 1113 (S1201). The identifying unit 1115 determines whether or not the data input screen is included in the screen management data (S1203). In the present embodiment, the specifying unit 1115 reads the data input screen from the data input screen list storage unit 1117.

  When it is determined that the data input screen is not included in the screen management data, the process returns to S1201.

  If it is determined that the data input screen is included in the screen management data, the specifying unit 1115 specifies the touch panel displaying the data input screen (S1205). Then, control processing is executed (S1207).

  FIG. 13 to FIG. 17 show examples of control processing flows. First, the control process shown in FIG. 13 will be described. The determination unit 1119 activates the timer A (S1301). The determination unit 1119 determines whether an event has occurred in the touchpad of the touch panel specified in S1205 (S1303). If it is determined that an event has occurred in the touchpad of the touch panel specified in S1205, the determination unit 1119 stops the timer A (S1305), ends the control process, and returns to the process of S1201 in FIG.

  If it is determined that the event on the touch panel specified in S1205 has not occurred, the acquisition unit 1111 acquires screen management data (S1307). The determination unit 1119 determines whether the screen management data has been updated (S1309). The determination unit 1119 determines that the screen management data has been updated when the screen management data acquired in S1307 is different from the screen management data stored in the screen management data storage unit 1113.

  If it is determined that the screen management data has been updated, the determination unit 1119 stops the timer A (S1305), ends the control process, and returns to the process of S1201 in FIG. For example, if the soft keyboard screen is no longer displayed, the control process ends and the process returns to S1201 in FIG.

  If it is determined that the screen management data has not been updated, the determination unit 1119 determines whether or not the elapsed time measured by the timer A has exceeded the time length T1 (S1311). If it is determined that the elapsed time measured by the timer A does not exceed the time length T1, the process returns to S1303. The iterative process from S1303 to S1311 corresponds to the continuation of the normal mode.

  When the elapsed time measured by the timer A exceeds the time length T1, the power saving mode A is entered. Therefore, when it is determined that the elapsed time measured by the timer A has exceeded the time length T1, the reduction unit 1123 instructs to decrease the brightness of the touch panel display specified in S1205 (S1313). Then, the processing proceeds to S1401 in FIG.

  Next, the control process shown in FIG. 14 will be described. The determination unit 1119 determines whether a return instruction A has been received (S1401). For example, it is determined that the return instruction A has been received when an event has occurred on the touchpad of the touch panel identified in S1205.

  If it is determined that the return instruction A has been received, the return unit 1125 instructs the brightness change to return the brightness of the touch panel display specified in S1205 (S1403). Further, the determination unit 1119 stops the timer A (S1405), finishes the control process, and returns to the process of S1201 in FIG.

  If it is determined that the return instruction A has not been received, the acquisition unit 1111 acquires screen management data (S1407). The determination unit 1119 determines whether the screen management data has been updated as in S1309 (S1409).

  If it is determined that the screen management data has been updated, the return unit 1125 instructs the luminance change so as to return the luminance of the touch panel display specified in S1205 (S1403). Further, the determination unit 1119 stops the timer A (S1405), finishes the control process, and returns to the process of S1201 in FIG. For example, when the outgoing mail editing screen is not displayed, the normal mode is restored.

  If it is determined that the screen management data has not been updated, the determination unit 1119 determines whether or not the elapsed time measured by the timer A has exceeded the time length T2 (S1411). If it is determined that the elapsed time measured by the timer A does not exceed the time length T2, the process returns to S1401. The iterative process from S1401 to S1411 corresponds to the continuation of the power saving mode A.

  When the elapsed time measured by the timer A exceeds the time length T2, the power saving mode B is entered. Therefore, when it is determined that the elapsed time measured by the timer A has exceeded the time length T2, the pause unit 1127 pauses the touch panel display specified in S1205 (S1413), and touches the touch panel specified in S1205. The pad is paused (S1415). Further, the determination unit 1119 stops the timer A (S1417). Then, the process proceeds to S1501 in FIG.

  Next, the control process shown in FIG. 15 will be described. The determination unit 1119 activates the timer B (S1501). The determination unit 1119 determines whether or not a return instruction B has been received (S1503). For example, when a key 105 pressing event occurs, it is determined that the return instruction B has been received.

  If it is determined that the return instruction B has been received, the return unit 1125 returns the paused display (S1505), and instructs the brightness change to return the brightness of the returned display (S1507). Further, the return unit 1125 returns the paused touch pad (S1509). Further, the determination unit 1119 stops the timer B (S1511), finishes the control process, and returns to the process of S1201 in FIG.

  If it is determined that the return instruction B has not been received, the acquisition unit 1111 acquires screen management data (S1513). The determination unit 1119 determines whether the screen management data has been updated as in S1309 (S1515).

  If it is determined that the screen management data has been updated, the return unit 1125 returns the paused display (S1505), and instructs the brightness change to return the brightness of the restored display (S1507). Further, the return unit 1125 returns the paused touch pad (S1509). Then, the determination unit 1119 stops the timer B (S1511), finishes the control process, and returns to the process of S1201 in FIG. For example, when the outgoing mail editing screen is not displayed, the normal mode is restored.

  If it is determined that the screen management data has not been updated, the determination unit 1119 determines whether an event has occurred in the touchpad of the other touch panel (a touch panel other than the touch panel specified in S1205) (S1517). . If it is determined that an event has occurred in the touchpad of the other touch panel, the determination unit 1119 stops the timer B (S1519), returns to S1501, and starts the timer B again. That is, the determination unit 1119 resets the timer B and restarts it.

  If it is determined that no event has occurred in the touchpad of the other touch panel, the determination unit 1119 determines whether or not the elapsed time measured by the timer B has exceeded the time length T3 (S1521).

  If it is determined that the elapsed time measured by the timer B does not exceed the time length T3, the process returns to S1503. The iterative process from S1503 to S1521 corresponds to the continuation of the power saving mode B.

  When the elapsed time measured by the timer B exceeds the time length T3, the process shifts to the power saving mode C. Therefore, when it is determined that the elapsed time measured by the timer B has exceeded the time length T3, the reduction unit 1123 reduces the display brightness of the other touch panel (the touch panel other than the touch panel specified in S1205). An instruction is given (S1523). Then, the processing proceeds to S1601 in FIG.

  Next, the control process shown in FIG. 16 will be described. The determination unit 1119 determines whether or not a return instruction C has been received (S1601). For example, when a key 105 pressing event occurs, it is determined that a return instruction C has been received.

  If it is determined that the return instruction C has been received, the return unit 1125 returns the paused display (S1603), and instructs the brightness change to return the brightness of the returned display (S1605). Furthermore, the return unit 1125 returns the paused touch pad (S1607). In addition, the return unit 1125 instructs to change the luminance so as to return the luminance of the display of the other touch panel (a touch panel other than the touch panel specified in S1205) (S1609). The determination unit 1119 stops the timer B (S1611), finishes the control process, and returns to the process of S1201 in FIG.

  If it is determined that the return instruction C has not been received, the acquisition unit 1111 acquires screen management data (S1613). The determination unit 1119 determines whether the screen management data has been updated as in S1309 (S1615).

  If it is determined that the screen management data has been updated, the return unit 1125 returns the paused display (S1603), and instructs the brightness change to return the brightness of the restored display (S1605). Furthermore, the return unit 1125 returns the paused touch pad (S1607). In addition, the return unit 1125 instructs to change the luminance so as to return the luminance of the display of the other touch panel (a touch panel other than the touch panel specified in S1205) (S1609). The determination unit 1119 stops the timer B (S1611), finishes the control process, and returns to the process of S1201 in FIG. For example, when the outgoing mail editing screen is not displayed, the normal mode is restored.

  If it is determined that the screen management data has not been updated, the determination unit 1119 determines whether a return instruction D has been received (S1617). The determination unit 1119 determines that the return instruction D has been received, for example, when an event has occurred in the touchpad of the other touch panel (a touch panel other than the touch panel specified in S1205).

  If it is determined that the return instruction D has been received, the return unit 1125 instructs to change the brightness so as to return the brightness of the display of the other touch panel (a touch panel other than the touch panel specified in S1205) (S1619). The determination unit 1119 stops the timer B (S1621), returns to S1501 via the terminal B, and starts the timer B again. That is, the determination unit 1119 resets the timer B and restarts it.

  If it is determined that the return instruction D has not been received, the determination unit 1119 determines whether or not the elapsed time measured by the timer B has exceeded the time length T4 (S1623).

  If it is determined that the elapsed time measured by the timer B does not exceed the time length T4, the process returns to S1601. The iterative process from S1601 to S1623 corresponds to the continuation of the power saving mode C.

  When the elapsed time measured by the timer B exceeds the time length T4, the process shifts to the power saving mode D. Therefore, when it is determined that the elapsed time measured by the timer B has exceeded the time length T4, the pause unit 1127 pauses the display of the other touch panel (the touch panel other than the touch panel specified in S1205) (S1625). Furthermore, the touch pad of the other touch panel is also suspended (S1627). Then, the determination unit 1119 stops the timer B (S1629). Then, the process proceeds to S1701 in FIG.

  Next, the control process shown in FIG. 17 will be described. The determination unit 1119 determines whether or not a return instruction F has been received (S1701). For example, when a key 105 pressing event occurs, it is determined that the return instruction F has been received.

  If it is determined that the return instruction F has been received, the return unit 1125 returns the display that was previously paused in S1413 (S1703), and instructs the brightness change to return the brightness of the returned display (S1705). ). Further, the return unit 1125 returns the touch pad previously paused in S1415 (S1707).

  Subsequently, the restoration unit 1125 restores the display that has been paused in S1625 (S1709), and instructs the luminance change to restore the restored display brightness (S1711). Further, the restoration unit 1125 restores the touch pad that was paused later in S1627 (S1713). Then, the control process is finished, and the process returns to S1201 in FIG.

  If it is determined that the return instruction F has not been received, the acquisition unit 1111 acquires screen management data (S1715). The determination unit 1119 determines whether the screen management data has been updated as in S1309 (S1717).

  If it is determined that the screen management data has been updated, the restoration unit 1125 restores the display that has been paused in S1413 (S1703), and instructs the luminance change to restore the restored display brightness (S1703). S1705). Further, the return unit 1125 returns the touch pad previously paused in S1415 (S1707).

  Subsequently, the restoration unit 1125 restores the display that has been paused in S1625 (S1709), and instructs the luminance change to restore the restored display brightness (S1711). Further, the restoration unit 1125 restores the touch pad that was paused later in S1627 (S1713). Then, the control process is finished, and the process returns to S1201 in FIG.

  If it is determined that the screen management data has not been updated, the process returns to S1701. This is the end of the description of the processing flow.

  According to the present embodiment, it is possible to suppress power consumption caused by continuously displaying a data input screen (for example, a soft keyboard screen) that can be assumed to be unnecessary due to completion of acceptance of data input. .

  Moreover, power consumption can be suppressed by stopping the display of a data input screen (for example, a soft keyboard screen) that can be presumed to be unnecessary.

  In addition, power consumption can be further suppressed by stopping waiting for an operation corresponding to the display of a data input screen (for example, a soft keyboard screen) that can be assumed to be unnecessary.

[Embodiment 2]
In the above-described embodiment, an example in which the touch panel displaying the data input screen is specified based on the data input screen list is shown. However, in this embodiment, the target touch panel set for each specific target program An example of specifying the will be described.

  In the above-described embodiment, an example in which the outgoing mail editing screen provided by the mailer 1105 (an example of the application unit) and the soft keyboard screen provided by the operating system 1101 are displayed has been described. The example which displays the equalizer screen and spectrum display screen which (example of an application part) provide is shown.

  The equalizer screen is a screen for accepting input of control data for changing the frequency characteristics of a sound signal to be reproduced, for example. The spectrum display screen is, for example, a screen for displaying a graph of the frequency characteristics of the sound signal changed according to the control data.

  In this embodiment, an example of use in the left-right state is shown. FIG. 18 is a perspective view of the mobile terminal device 100 in the left-right open state. The first display 221a of the first touch panel 101 displays a left screen, and the first touch pad 223a of the first touch panel 101 detects a touch operation on the left screen. In this example, the first display 221a of the first touch panel 101 displays an equalizer screen, and the first touch pad 223a of the first touch panel 101 detects a touch operation on the equalizer screen. The equalizer screen is displayed by the music player via the operating system 1101.

  The second display 221b of the second touch panel 103 displays the right screen, and the second touch pad 223b of the second touch panel 103 detects a touch operation on the right screen. In this example, the second display 221b of the second touch panel 103 displays a spectrum display screen. The spectrum display screen is displayed by the music player via the operating system 1101.

  Therefore, the state of the graph displayed on the spectrum display screen changes according to the touch operation on the equalizer screen.

  The mobile terminal device 100 according to the present embodiment includes a list of programs to be screen controlled in advance. FIG. 19 shows an example of the target program list. As an example of the target program, a music player is shown in the first record, and a game is shown in the second record.

  Moreover, the information which identifies the touch panel (it is called a target touch panel) which displays the screen which lowers | hangs brightness | luminance first and is made to pause first among the several screens which an object program provides is included.

  In this example, the equalizer screen provided by the music player is a kind of data input screen because it accepts input of control data used to generate the spectrum display screen. In this example, the first touch panel on which an equalizer screen that is a data input screen is displayed is defined as the target touch panel. When the state where the operation using the equalizer screen is not performed continues, the power consumption is suppressed by reducing the luminance of the first touch panel that displays the equalizer screen or pausing the first touch panel.

  Furthermore, the controller screen provided by the game is a kind of data input screen because it accepts input of control data used to generate the game screen. In this example, a second touch panel that displays a controller screen that is a data input screen is defined as a target touch panel. When the state where the operation on the controller screen is not performed continues, the power consumption is suppressed by reducing the brightness of the second touch panel displaying the controller screen or pausing the second touch panel.

  The mode according to the second embodiment will be described with reference to FIG. As in the above-described embodiment, the power saving modes A to D are provided in addition to the normal mode. FIG. 20 assumes that the equalizer screen is displayed on the first display 221a and the spectrum display screen is displayed on the second display 221b. Each record indicates the state of the first display 221a, the state of the first touch pad 223a, the state of the second display 221b, and the state of the second touch pad 223b in each mode, as in FIG.

  As shown in the first record, in the normal mode, both the first display 221a and the second display 221b display each screen with normal luminance, and both the first touch pad 223a and the second touch pad 223b operate.

  As shown in the second record, in the power saving mode A, the first display 221a displaying the equalizer screen has a low luminance. However, the second display 221b remains at the normal luminance. Both the first touch pad 223a and the second touch pad 223b operate.

  As shown in the third record, in the power saving mode B, the first display 221a and the first touch pad 223a are suspended. The second display 221b remains at normal brightness, and the second touchpad 223b also operates.

  As shown in the fourth record, in the power saving mode C, the first display 221a and the first touch pad 223a remain at rest. The second display 221b displaying the spectrum display screen has a low luminance. The second touch pad 223b operates.

  As shown in the fifth record, in the power saving mode D, both the second display 221b and the second touch pad 223b are suspended. The first display 221a and the first touch pad 223a remain at rest.

  As described above, in the power saving mode A, the equalizer screen first becomes low brightness, and in the power saving mode B, the display of the equalizer screen disappears, and the touch detection on the equalizer screen is also stopped. Further, in the power saving mode C, the display of the spectrum display screen becomes low brightness, and in the power saving mode D, the display of the spectrum display screen disappears and the touch detection on the spectrum display screen is also stopped.

  As in the above-described embodiment, when time elapses without being operated, the normal mode, the power saving mode A, the power saving mode B, the power saving mode C, and the power saving mode D are changed in this order. The mode transition is as described with reference to FIG.

  FIG. 21 shows an example of a sequence according to the second embodiment. The mobile terminal device 100 according to the present embodiment includes a music player 2201 in addition to the operating system 1101 and the screen control unit 1103. The music player 2201 is an application unit that reproduces music data and provides an equalizer screen and a spectrum display screen.

  The music player 2201 generates spectrum display screen data and requests the operating system 1101 to display the spectrum display screen (S2101). The request for display of the designated screen sent from the music player 2201 to the operating system 1101 may include spectrum display screen data and information for specifying the display area. The information for specifying the spectrum display screen data is, for example, an identifier of a buffer that stores the spectrum display screen data. The information for specifying the display area is, for example, coordinates indicating the starting point.

  The operating system 1101 displays the requested designation screen (S2103). In this example, the second display 221b displays a spectrum display screen. The spectrum display screen data is updated as needed, and the second display 221b displays the updated spectrum display screen.

  The music player 2201 further generates equalizer screen data and requests the operating system 1101 to display the equalizer screen (S2105). The request for the designated screen display sent from the music player 2201 to the operating system 1101 may include equalizer screen data and information for specifying the display area. The information for specifying the equalizer screen data is, for example, an identifier of a buffer that stores the equalizer screen data. The information for specifying the display area is, for example, coordinates indicating the starting point.

  The operating system 1101 displays the requested designation screen (S2107). In this example, the first display 221a displays an equalizer screen. The equalizer screen data is updated according to the operation, and the first display 221a displays the updated spectrum display screen.

  The screen control unit 1103 acquires process management data from the operating system 1101 (S2109). The screen control unit 1103 identifies a program to be controlled and a display based on the process management data.

  Similar to the above-described embodiment, when a predetermined period elapses, the screen control unit 1103 instructs the operating system 1101 to change the luminance so that the luminance of the first display 221a is lowered (S2111).

  Further, when a predetermined period elapses, the screen control unit 1103 instructs the operating system 1101 to pause the first display 221a and further pause the first touch pad 223a (S2113).

  Further, when a predetermined period elapses, the screen control unit 1103 instructs the operating system 1101 to change the luminance so that the luminance of the second display 221b is lowered (S2115).

  Furthermore, when a predetermined period has elapsed, the screen control unit 1103 instructs the operating system 1101 to pause the second display 221b and further pause the second touch pad 223b (S2117). This is the end of the description of the sequence.

  Next, a module configuration example of the mobile terminal device 100 according to Embodiment 2 will be described with reference to FIG. The mobile terminal device 100 includes a music player 2201 instead of the mailer 1105 as an application unit according to the second embodiment. The screen control unit 1103 according to the second embodiment has a target program list storage unit 2203 instead of the data input screen list storage unit 1117. The target program list storage unit 2203 stores, for example, the target program list shown in FIG.

  Next, a main processing flow by the screen control unit 1103 according to the second embodiment will be described with reference to FIG. The acquisition unit 1111 acquires screen management data and process management data from the operating system 1101, and stores the acquired screen management data in the screen management data storage unit 1113 (S2301).

  The identifying unit 1115 determines whether or not a process by any target program is included in the process management data (S2303).

  If it is determined that the process management data does not include any process by the target program, the process returns to S2301.

  When it is determined that the process management data includes a process by any one of the target programs, the specifying unit 1115 specifies a target touch panel corresponding to the target program (S2305). Then, control processing is executed (S2307). In this example, it is determined that the process of the music player 2201 is included in the process management data.

  The control process is the same as that in the above embodiment. In the present embodiment, the “specified touch panel” in S1313 in FIG. 13 and S1413 and S1415 in FIG. 14 is the touch panel specified in S2305.

  In this embodiment, “the other touch panel” in S1523 in FIG. 15 and S1625 and S1627 in FIG. 16 is a touch panel other than the touch panel specified in S2305.

  In the present embodiment, it is possible to specify the display and the touchpad related to the data input screen and change the brightness or pause without using the data input screen list (FIG. 3) shown in the first embodiment. .

  According to the present embodiment, it is possible to suppress power consumption caused by continuously displaying a data input screen (for example, an equalizer screen) that can be presumed to be unnecessary due to completion of acceptance of data input.

  Moreover, power consumption can be suppressed by stopping the display of a data input screen (for example, an equalizer screen) that can be presumed to be unnecessary.

  In addition, power consumption can be further suppressed by stopping waiting for an operation corresponding to the display of a data input screen (for example, an equalizer screen) that can be assumed to be unnecessary.

[Embodiment 3]
In the above-described embodiment, an example of suppressing the power consumption of the touch panel displaying the data input screen has been shown. However, in this embodiment, an operation for calling the screen displayed on one touch panel is prompted. The example which suppresses the power consumption which concerns on the other touch panel which is displaying another screen is demonstrated.

  In the present embodiment, an example is shown in which a received mail browsing screen provided by mailer 1105 (an example of an application unit) and a browser screen provided by a browser called based on a hyperlink in the received mail are displayed.

  In this example, the brightness of the display of the touch panel displaying the received mail browsing screen that prompts the operation for calling the browser screen is lowered first, and further, the display on the touch panel display and the touch detection on the touch pad of the touch panel And pause first.

  If the caller's screen is not needed in this way, when the callee's screen is displayed, the brightness of the display that displays the caller's screen is lowered first, or the display on the display and the display Even if the touch detection on the corresponding touch pad is suspended, no problem occurs.

  FIG. 24 shows an example of screen management data according to the third embodiment. As in FIG. 5, the screen management data has a record for each screen being displayed. The record of the screen management data in the present embodiment includes a field indicating the operating program and a field indicating the calling source program in addition to the field of the area displaying the screen being displayed.

  The operating program is a program that realizes an application unit that generates a screen being displayed and displays the screen via the operating system 1101. The caller program is a program that realizes an application unit that calls an operating program.

  The first record is generated by the mailer 1105 in the received mail browsing screen displayed in the display area specified by the coordinates (X7, Y7) of the upper left end point and the coordinates (X8, Y8) of the lower right end point on the second display 221b. This indicates that the mailer is displaying a received mail browsing screen via the operating system 1101.

  In the second record, the browser screen displayed in the display area specified by the coordinates (X5, Y5) of the upper left end point and the coordinates (X6, Y6) of the lower right end point on the first display 221a is generated by the browser. Indicates that the browser screen is displayed via the operating system. The second record further indicates that the browser has been invoked by the mailer.

  The calling relationship between the calling source program and the calling destination program may be specified based on other data such as process management data.

  A display area of each display in the left and right opening will be described. FIG. 25 shows an example of the display area in the left-right direction. The left rectangle shows the display area of the first display 221 a of the first touch panel 101. In this example, the position in the display area of the first display 221a is indicated by coordinates. The coordinates (X5, Y5) indicate the upper left end point in the display area of the first display 221a. The coordinates (X6, Y5) indicate the upper right end point in the display area of the first display 221a. The coordinates (X5, Y6) indicate the lower left end point in the display area of the first display 221a. The coordinates (X6, Y6) indicate the lower right end point in the display area of the first display 221a.

  The rectangle on the right side indicates the display area of the second display 221b of the second touch panel 103. In this example, the position of the display area of the second display 221b is indicated by coordinates. The coordinates (X7, Y7) indicate the upper left end point in the display area of the second display 221b. The coordinates (X8, Y7) indicate the upper right end point in the display area of the second display 221b. The coordinates (X7, Y8) indicate the lower left end point in the display area of the second display 221b. The coordinates (X8, Y8) indicate the lower right end point in the display area of the second display 221b.

  Here, an example is shown in which the positions in the display area of the first display 221a and the second display 221b are specified by coordinates, but the display areas of the first display 221a and the second display 221b are determined by combinations of touch panel identifiers and coordinates. You may make it pinpoint the position in. This is the end of the description of the display area of each display.

  Next, the mode according to Embodiment 3 will be described with reference to FIG. As in the above-described embodiment, the power saving modes A to D are provided in addition to the normal mode. FIG. 26 is based on a situation in which the browser screen is displayed on the first display 221a and the received mail browsing screen is displayed on the second display 221b. Each record indicates the state of the first display 221a, the state of the first touch pad 223a, the state of the second display 221b, and the state of the second touch pad 223b in each mode, as in FIGS.

  As shown in the first record, in the normal mode, both the first display 221a and the second display 221b display each screen with normal luminance, and both the first touch pad 223a and the second touch pad 223b operate.

  As shown in the second record, in the power saving mode A, the second display 221b displaying the received mail browsing screen has a low luminance. However, the first display 221a remains at the normal luminance. Both the first touch pad 223a and the second touch pad 223b operate.

  As shown in the third record, in the power saving mode B, the second display 221b and the second touch pad 223b are suspended. The first display 221a remains at normal brightness, and the first touch pad 223a also operates.

  As shown in the fourth record, in the power saving mode C, the second display 221b and the second touch pad 223b remain at rest. The first display 221a displaying the browser screen has low brightness. The first touch pad 223a operates.

  As shown in the fifth record, in the power saving mode D, both the first display 221a and the first touch pad 223a are suspended. The second display 221b and the second touch pad 223b remain at rest.

  Thus, in the power saving mode A, the received mail browsing screen is first reduced in brightness, and in the power saving mode B, the received mail browsing screen disappears, and touch detection on the received mail browsing screen is also paused. Further, in the power saving mode C, the display of the browser screen becomes low brightness, and in the power saving mode D, the display of the browser screen disappears and the touch detection on the browser screen is also stopped.

  As in the above-described embodiment, when time elapses without being operated, the normal mode, the power saving mode A, the power saving mode B, the power saving mode C, and the power saving mode D are changed in this order. The mode transition is as described with reference to FIG.

  FIG. 27 shows an example of a sequence according to the third embodiment. The mobile terminal device 100 includes a browser 2801 in addition to the mailer 1105 as an example of an application unit.

  The mailer 1105 generates received mail browsing screen data and requests the operating system 1101 to display the received mail browsing screen (S2701). The designation screen display request sent from the mailer 1105 to the operating system 1101 may include received mail browsing screen data and information for specifying the display area. The information for specifying the received mail browsing screen data is, for example, an identifier of a buffer that stores the received mail browsing screen data. The information for specifying the display area is, for example, coordinates indicating the starting point.

  The operating system 1101 displays the requested designation screen (S2703). In this example, the second display 221b displays a received mail browsing screen.

  When the operating system 1101 detects a hyperlink instruction operation on the received mail browsing screen (S2705), the operating system 1101 analyzes the instruction and specifies a URL (Uniform Resource Locator) of the link destination (S2707). The operating system 1101 then activates the browser 2801 by specifying the link destination URL (S2709).

  The browser 2801 generates browser screen data and requests the operating system 1101 to display the browser screen (S2711). The designation screen display request sent from the browser 2801 to the operating system 1101 may include browser screen data and information for specifying the display area. The information for specifying the browser screen data is, for example, an identifier of a buffer that stores the browser screen data. The information for specifying the display area is, for example, coordinates indicating the starting point.

  The operating system 1101 displays the requested designation screen (S2713). In this example, the browser screen is displayed on the first display 221a. The linked content is displayed in the browser screen.

  The screen control unit 1103 acquires screen management data from the operating system 1101 (S2715).

  Similar to the above-described embodiment, when a predetermined period elapses, the screen control unit 1103 instructs the operating system 1101 to change the luminance so that the luminance of the second display 221b is lowered (S2717).

  Furthermore, when a predetermined period has elapsed, the screen control unit 1103 instructs the operating system 1101 to pause the second display 221b and further pause the second touch pad 223b (S2719).

  Further, when a predetermined period elapses, the screen control unit 1103 instructs the operating system 1101 to change the luminance so that the luminance of the first display 221a is lowered (S2721).

  Further, when a predetermined period elapses, the screen control unit 1103 instructs the operating system 1101 to pause the first display 221a and further pause the first touch pad 223a (S2723).

  FIG. 28 shows a module configuration example of the mobile terminal device 100 according to the third embodiment. As described above, the mobile terminal device 100 includes the browser 2801 in addition to the mailer 1105 as the application unit according to the third embodiment. In the present embodiment, the screen control unit 1103 may not include the data input screen list storage unit 1117 shown in FIG. 11 and the target program list storage unit 2203 shown in FIG.

  FIG. 29 shows an example of a main processing flow by the screen control unit 1103 according to the third embodiment. The acquisition unit 1111 acquires screen management data from the operating system 1101 and stores the acquired screen management data in the screen management data storage unit 1113 (S2901). The identifying unit 1115 determines whether there is a calling relationship between the active programs included in the screen management data (S2903).

  If it is determined that there is no calling relationship between the active programs included in the screen management data, the process returns to S2901.

  If it is determined that the operating programs included in the screen management data have a calling relationship, the specifying unit 1115 specifies the touch panel displaying the screen by the calling source program (S2905). Then, the control process is executed (S2907).

  The control process is the same as that in the above embodiment. In the present embodiment, the “specified touch panel” in S1313 of FIG. 13 and S1413 and S1415 of FIG. 14 is the touch panel specified in S2905.

  In this embodiment, “the other touch panel” in S1523 in FIG. 15 and S1625 and S1627 in FIG. 16 is a touch panel other than the touch panel specified in S2905.

  The caller screen and the callee screen are not limited to the received mail browsing screen and the browser screen. For example, another browser screen may be called from a certain browser screen. Further, the image display screen may be called from the image list screen.

  According to the present embodiment, the caller's screen (in this example, the received mail browsing screen) that can be assumed to be unnecessary by calling the callee's screen (in this example, the browser screen) is continued. Power consumption due to display can be suppressed.

  Moreover, power consumption can be suppressed by stopping the display of the caller's screen that can be assumed to be unnecessary.

  In addition, power consumption can be further suppressed by stopping waiting for an operation according to the display of the caller's screen that can be assumed to be unnecessary.

[Embodiment 4]
In this embodiment, an example in which display specifying processing in Embodiments 1 to 3 is sequentially performed will be described.

  The screen control unit 1103 of the mobile terminal device 100 according to the present embodiment includes the modules shown in FIGS. 11, 22, and 28.

  FIG. 30 shows an example of a main processing flow by the screen control unit 1103 according to the fourth embodiment. The acquisition unit 1111 acquires screen management data and process management data from the operating system 1101, and stores the acquired screen management data in the screen management data storage unit 1113 (S3001).

  The specifying unit 1115 determines whether or not a data input screen is included in the screen management data (S3003). The specifying unit 1115 specifies the data input screen based on the data input screen list storage unit 1117 as in the first embodiment.

  If it is determined that the data input screen is included in the screen management data, the specifying unit 1115 specifies the touch panel displaying the data input screen (S3005). Then, control processing is executed (S3007). The control process is the same as in the first embodiment.

  If it is determined that the data input screen is not included in the screen management data, the specifying unit 1115 determines whether the process management data includes a process by any target program (S3009).

  When it is determined that any process by the target program is included in the process management data, the specifying unit 1115 specifies the target touch panel as in the second embodiment (S3011). Then, control processing is executed (S3013). The control process is the same as in the second embodiment.

  When it is determined that any process by any target program is not included in the process management data, the specifying unit 1115 determines whether there is a calling relationship between the active programs included in the screen management data ( S3015).

  When it is determined that there is a calling relationship between the active programs included in the screen management data, the specifying unit 1115 specifies the touch panel displaying the screen by the calling source program, as in the third embodiment. (S3017). Then, the control process is executed (S3019).

  If it is determined that there is no calling relationship between the active programs included in the screen management data, the process returns to S3001.

  Moreover, also when the control processing of S3007, S3013, and S3019 is completed, it returns to S3001.

  According to the present embodiment, it is possible to deal with any of the display screen modes shown in the first to third embodiments.

  Although one embodiment of the present technology has been described above, the present technology is not limited to this. For example, the functional block configuration described above may not match the actual program module configuration.

  Further, the configuration of each storage area described above is an example, and the above configuration is not necessarily required. Further, in the processing flow, the processing order can be changed if the processing result does not change. Further, it may be executed in parallel.

  The embodiment described above is summarized as follows.

  The mobile terminal device according to one aspect includes a plurality of display devices and the other display device displaying a second screen for receiving input of data used for generating a first screen displayed on one display device And a reduction unit that reduces the luminance of the other display device specified when the period during which the predetermined operation is not received exceeds the first time length.

  If it does in this way, the power consumption by displaying the 2nd screen which can be estimated that it became unnecessary after having completed acceptance of data input can be controlled.

  In addition, when the second screen is not displayed on any of the plurality of display devices, the specifying unit displays a fourth screen that prompts an operation for calling the third screen displayed on one display device. The other display device may be specified. Furthermore, when the period during which the predetermined operation is not received exceeds the first time length, the reduction unit may reduce the luminance in the other specified display device.

  If it does in this way, the power consumption by displaying continuously the 4th screen which may be guessed that it became unnecessary by calling the 3rd screen can be controlled.

  The portable terminal device may include a pause unit that pauses the other specified display device when the period during which the predetermined operation is not received exceeds the second time length.

  In this way, it is possible to suppress power consumption by stopping the display of the second screen or the fourth screen that can be assumed to be unnecessary as described above.

  When the specified other display device is paused, the pause unit may pause the input device linked to the identified other display device.

  In this way, it is possible to further suppress power consumption by stopping waiting for an operation according to the display of the second screen or the fourth screen that can be assumed to be unnecessary as described above.

  A program for causing the processor to perform the above processing can be created. The program is, for example, a computer-readable storage medium or storage device such as a flexible disk, a CD-ROM, a magneto-optical disk, a semiconductor memory, or a hard disk. You may make it store in. Note that intermediate processing results are generally temporarily stored in a storage device such as a main memory.
