<< Embodiment >>
<1. Overview>
A mobile phone according to an embodiment includes a first display (LCD display) disposed in a first housing and a second display (electrophoretic electronic paper display) disposed in a second housing. It is. The first display, which is an LCD display, has a higher refresh rate than the second display, which is an electrophoretic electronic paper display.

  The mobile phone further includes an acceleration sensor, and displays each content so that the orientation of the housing specified by the detected acceleration matches the top of each content. In particular, when two application programs having different screen update frequencies in content display processing are executed, the mobile phone uses the content of the application program having the higher screen update frequency as the first display and the other application program. The contents of the program are displayed on the second display.

Therefore, according to this mobile phone, flickering of content such as a moving image whose display update frequency is relatively high in display processing is suppressed while displaying the user so that the orientation in which the mobile phone is held matches the top of each content. Can be displayed in an easy-to-read manner.
Here, the content is information (for example, a character, an image, a moving image, and a combination thereof) that can be visually recognized by humans, and constitutes a group in terms of contents. For example, a moving image of a movie or a Web page made up of characters and images constitutes a group in terms of content, and thus is a single content.

<2. Device configuration>
First, the device configuration of the mobile phone 100 according to the embodiment will be described.
1A is a perspective view showing an external appearance of the mobile phone 100 in a closed state, FIG. 1B is a perspective view showing an external appearance of the mobile phone 100 in an open state, and FIG. FIG. 3 is a perspective view showing an external appearance of mobile phone 100 in a fully opened state.

As shown in FIGS. 1A to 1C, the mobile phone 100 is a sliding terminal in which the first housing 1 and the second housing 2 are relatively movable, and the first housing 1 1, a second housing 2 and an arm 3 that connects the first housing 1 and the second housing 2.
The first housing 1 includes a receiver 4, a microphone 5, a first display 110 and an acceleration sensor 140, a magnet 6 is built in, and the second housing 2 includes a second display 120. A magnetic sensor 7 is incorporated.

The base end side of the arm 3 is rotatably supported by the second housing 2, and the distal end side of the arm 3 supports the first housing 1 so that it can slide and rotate. Accordingly, the mobile phone 100 can be changed between the closed state, the open state, and the fully open state, as well as the first housing 1 and the second housing 2 simply rotating relative to each other.
As shown in FIG. 1A, the mobile phone 100 is moved from the closed state in which the first housing 1 is overlapped with the second housing 2 and the second display 120 cannot be visually recognized. Is moved along the main surface of the second housing 2 to be in the open state shown in FIG. 1 (b). As shown in FIG. 1 (c), the main surface of the first housing 1 and the second surface The main surface of the housing 2 is aligned on substantially the same plane, and the first display 110 and the second display 120 are fully opened. Here, the surface on the side where the display is present in each housing is expressed as a main surface.

The mobile phone 100 can determine whether or not the mobile phone 100 is in the closed state based on whether or not the magnetic sensor 7 detects the magnetic force of the magnet 6. That is, when the magnetic sensor 7 detects the magnetic force generated by the magnet 6, the mobile phone 100 determines that the mobile phone 100 is in the closed state, and when the magnetic sensor 7 does not detect it, the mobile phone 100 is not in the closed state, that is, the open state or the fully open state. It is determined that
<3. Display example>
Next, display examples of the mobile phone 100 will be described with reference to FIGS.

Hereinafter, as shown in FIG. 2A and FIG. 2B, the orientation of the mobile phone 100 in which the first housing 1 is disposed at the top and the second housing 2 is disposed at the bottom is referred to as “standard direction”.
FIG. 2A shows a case where the mobile phone 100 is in a standard direction, and in particular, by displaying content by a web browser (application program), “party” is input in the keyword input field of the video posting site, and the video is displayed. An example is shown in which images (contents) indicating the search results are displayed on each display.

It is assumed that, from the state of FIG. 2A, the user has selected the thumbnail image P1 among the thumbnail images indicating the search result of the moving image displayed on the second display 120.
Then, as shown in FIG. 2B, the mobile phone 100 starts executing an application program (hereinafter referred to as “Web content player”) for playing back a moving image, and the content performed by the Web content player. Through the display process, the moving image corresponding to the thumbnail image P1 is displayed on the first display 110. Further, as shown in FIG. 2B, the mobile phone 100 displays the image (content) of the moving image posting site displayed on each display in FIG. 2A on the second display 120.

  Here, the moving image displayed on the first display 110 and the image of the moving image posting site displayed on the second display 120 are each one content. Further, in order to display a moving image smoothly, it is assumed that the screen update frequency in the content display process performed by the Web content player is set higher than the screen update frequency in the content display process performed by the Web browser.

It is more refreshing that the mobile phone 100 displays the content (moving image in this example) to be displayed on the first display 110 by the display processing performed by the web content player as shown in FIG. This is because, when displayed on the second display with a low rate, the screen flickers and the visibility of the moving image deteriorates.
FIG. 3A shows an example in which an image (content) of a moving image posting site similar to FIG. 2A is displayed on each display. In FIGS. 2A and 3A, the relative positions of the casings 1 and 2 are reversed.

Similar to the case of FIG. 2A, the user selects the thumbnail image P1 from the thumbnail images indicating the search result of the moving image displayed on the first display 110 from the state of FIG. And
Then, as illustrated in FIG. 3B, the mobile phone 100 displays the moving image corresponding to the thumbnail image P <b> 1 on the first display 110 by the content display process performed by the Web content player that has started execution. Also, as shown in FIG. 3B, the mobile phone 100 displays the image (content) of the moving image posting site displayed on each display in FIG. 3A on the second display 120.

  Comparing FIG. 2 (b) and FIG. 3 (b), it can be seen that the relative positions of the two contents (images and moving images of the moving image posting site) displayed on the respective displays are different. That is, the mobile phone 100 displays the content of the application program with the higher screen update frequency (in this example, the Web content player) on the first display 110, thereby suppressing flickering and displaying the moving image in an easy-to-view manner for the user. .

Subsequently, from the state of FIG. 3B, it is assumed that the user rotates the direction of the mobile phone 100 by 90 degrees clockwise about an axis parallel to the z axis of the acceleration sensor 140 (FIG. 4A). )reference). The acceleration sensor 140 is a three-axis acceleration sensor that detects an xyz-axis acceleration component shown in FIG.
Then, the mobile phone 100 displays the content displayed on each display by rotating it 90 degrees clockwise from the display state shown in FIG. Before and after the cellular phone 100 is rotated 90 ° clockwise (FIGS. 3B and 4A), the cellular phone 100 does not change the display that is the display destination of each content.

Subsequently, it is assumed that, from the state shown in FIG. 4A, the user rotates the direction of the mobile phone 100 by 180 ° about the axis parallel to the z-axis of the acceleration sensor 140 (see FIG. 4B). ).
Then, the cellular phone 100 displays each content on each display so that the orientation of the own device specified based on the change in acceleration detected by the acceleration sensor 140 matches the top of each content. That is, the mobile phone 100 displays the moving image displayed on the first display 110 and the image of the moving image posting site displayed on the second display 120 by rotating 180 ° from the display state shown in FIG. To do. That is, when the mobile phone 100 is rotated 90 ° clockwise (FIGS. 3B and 4A), before and after the mobile phone 100 is rotated 180 ° (FIGS. 4A and 4B). In b)), the mobile phone 100 does not change the display to which each content is displayed.

  As a result, the video displayed on the left side of the video posting site image in FIG. 4A is displayed on the right side of the video posting site image in FIG. It seems that the relative positional relationship of the display of each content has changed. However, if the relative positional relationship of the display of each content is maintained even before and after 180 ° rotation, after 180 ° rotation, the moving image is displayed on the second display 120 with a lower refresh rate. . Therefore, the flickering of the screen occurs and the visibility of the moving image deteriorates. On the other hand, since the mobile phone 100 continues to display the moving image on the first display 110 before and after being rotated by 180 °, flickering can be suppressed and the mobile phone 100 can display it easily to the user.

  In the state shown in FIG. 5, when the user selects the thumbnail image P1, the mobile phone 100 performs display on each display as shown in FIG. That is, the mobile phone 100 displays the moving image corresponding to the thumbnail image P1 on the first display 110 and the moving image posting site image (contents) displayed on each display in FIG. ) Is displayed on the second display 120.

At this time, the display control unit 165 displays the orientation of the mobile phone 100 detected by the orientation detection unit 162 and the top and bottom of the content.

<5. Data>
Hereinafter, data used by the mobile phone 100 will be described with reference to FIG.
FIG. 7 is a diagram illustrating a data configuration and example contents of the update frequency table 10.
As shown in the figure, the update frequency table 10 includes, for each of various applications (application group 20) that can be executed by the mobile phone 100 stored in the storage unit 150, ID11, name 12, version information 13, This is information configured by associating the producer 14 with the screen update frequency 15.

Below, the data consisting of the corresponding ID, name, version information, producer, and screen update frequency is also referred to as “record”.
Of the records in the update frequency table 10, a record for a basic application program stored since the start of operation of the mobile phone 100 is registered in advance by the manufacturer of the mobile phone 100, and thereafter Records about application programs acquired from the apparatus are registered by the acquisition unit 163.

Here, ID11 is identification information of the application program, and in this example, a number increased by 1 from the initial value “1” is used. When the acquisition unit 163 registers an ID for an application program acquired from an external device in the update frequency table 10, a number obtained by adding 1 to the maximum registered ID is used.
The name 12 is information indicating the name of the application program indicated by the corresponding ID, the version information 13 is information indicating the version of the application program, and the producer 14 is a company or the like that has developed the application program. It is the information which shows the name of.

Further, in the same figure, the screen update frequency 15 (“60” Hz) of the application program (Web content player) whose ID 11 is “2” is higher than the application program (Web browser) whose ID 11 is “1”. It is shown that.

<6. Operation>
Next, the operation of the mobile phone 100 will be described with reference to FIGS.
8 and 9 are flowcharts showing control processing of the mobile phone 100. FIG.
The control process shown in the figure is started when the power of the mobile phone 100 is turned on, and is ended when the power is turned off, although not particularly shown.

  In addition, as a process independent of the control process shown in the figure, a process for updating the state information 30 in the storage unit 150 so as to indicate the current state of the mobile phone 100 based on a signal output from the magnetic sensor 7. Is performed by the state detection unit 161. In addition, as a process independent of the control process shown in the figure, the direction detection unit 162 performs a process of updating the direction information 40 in the storage unit 150 so as to indicate the current direction of the mobile phone 100.

  First, when the power of the mobile phone 100 is turned on, the application execution unit 164 of the control unit 160 reads out and executes a menu application program that performs display processing of a menu image including a plurality of icons from the storage unit 150 (application group 20). To start. At this time, the application execution unit 164 stores the first and second application information (A1, A2) and the first and second screen update frequency information (F1, F2) in the storage unit 150 (FIG. 8). Step S1). Specifically, the application execution unit 164 displays the ID (“5” in the example of FIG. 7) and the screen update frequency (“15” in the example of FIG. 7) of the menu application program that has started execution of the update frequency table 10. Get from. Then, the application execution unit 164 stores the acquired ID in the storage unit 150 as the first application information A1 in the storage unit 150 and the acquired screen update frequency as the first screen update frequency information F1. In addition, the application execution unit 164 stores the initial value “0” in the storage unit 150 as the second application information A2 and the second screen update frequency information F2.

  Subsequently, the display control unit 165 determines whether or not the current state of the mobile phone 100 indicated by the state information 30 in the storage unit 150 is a closed state (step S2). When it is determined that the display control unit 165 is in the closed state (step S2: YES), the application program being executed tries to display the current orientation of the mobile phone 100 indicated by the orientation information 40 of the storage unit 150. The content is displayed on the first display 110 (step S3).

  Subsequently, the application execution unit 164 determines whether the current state of the mobile phone 100 indicated by the state information 30 in the storage unit 150 or the current direction of the mobile phone 100 indicated by the orientation information 40 in the storage unit 150 has changed, or the user operation is performed. It is determined whether it has been performed (step S4). If there is no change in the current state and orientation of the mobile phone 100 and no user operation is performed (step S4: NO), the application execution unit 164 performs the process of step S4 again.

  In addition, the application execution unit 164 determines that a user operation has been performed when coordinate values are output from any of the controllers (113, 123), and in particular, an operation that causes the user operation to start the application program from the coordinate values. For example, when it is an operation for selecting an icon in the menu image (step S4: activation operation), the following processing is performed. That is, the application execution unit 164 reads the application program corresponding to the selected icon from the storage unit 150 (the application group 20) and starts executing it, and the first application information A1 and the first screen update frequency information in the storage unit 150 are started. F1 is updated (step S5). Specifically, the application execution unit 164 acquires the ID of the application program that has started execution and the screen update frequency from the update frequency table 10, and acquires the first application information A1 with the acquired screen update frequency using the acquired ID. The one-screen update frequency information F1 is updated. When the process of step S5 is completed, the control unit 160 performs the process from step S2 again.

Further, when there is a change in the current state or orientation of the mobile phone 100 in step S4, or when the user operation performed is other than an operation for starting the application program (step S4: change, other operation). The control unit 160 performs the processing from step S2 again.
If the display control unit 165 determines in step S2 that the mobile phone 100 is not in the closed state (step S2: NO), the application program being executed in the current orientation of the mobile phone 100 indicated by the orientation information 40 in the storage unit 150 is displayed. The contents to be displayed are displayed on the first and second displays (110, 120) (step S6). For example, in the case where the orientation of the mobile phone 100 is the orientation shown in FIG. 3A, when the menu application program is being executed, the top direction (upper part) of the menu image is on the side 2A side of the second housing 2. The menu image is displayed on each display (110, 120).

  Subsequently, the application execution unit 164 determines whether the current state or orientation of the mobile phone 100 has changed or a user operation has been performed, as in the process of step S4 (step S7). If there is no change in the current state and orientation of the mobile phone 100 and no user operation is performed (step S7: NO), the application execution unit 164 performs the process of step S7 again.

In addition, the application execution unit 164 changes when the current state or orientation of the mobile phone 100 is changed, or when the user operation performed is other than an operation for starting the application program (Step S7: Change, etc. Operation), the control unit 160 performs the processing from step S2 again.
In addition, when an operation for starting an application program is performed (step S7: start operation), the application execution unit 164 reads the application program from the storage unit 150 (application group 20) and starts execution. Then, the application execution unit 164 updates the second application information A2 and the second screen update frequency information F2 in the storage unit 150 (Step S8). Specifically, the application execution unit 164 acquires the ID and screen update frequency of the application program that has started execution from the update frequency table 10, and uses the acquired ID to obtain the second application information A2 with the acquired screen update frequency. The two-screen update frequency information F2 is updated.

When the process of step S8 is completed, the display control unit 165 reads the first and second screen update frequency information (F1, F2) from the storage unit 150. Then, the display control unit 165 determines whether the screen update frequency indicated by the second screen update frequency information F2 is higher than the screen update frequency indicated by the first screen update frequency information F1 (step S9 in FIG. 9).
When the screen update frequency indicated by the second screen update frequency information F2 is equal to or lower than the screen update frequency indicated by the first screen update frequency information F1 (step S9: NO), the display control unit 165 displays the orientation information 40 of the storage unit 150. The display is controlled in the following manner with the current orientation of the mobile phone 100 shown in FIG. That is, the display control unit 165 displays the content of the application program indicated by the first application information A1 on the first display 110 and the content of the application program indicated by the second application information A2 on the second display 120 (step S10).

  On the other hand, when the screen update frequency indicated by the second screen update frequency information F2 is higher (step S9: YES), the display control unit 165 uses the current orientation of the mobile phone 100 indicated by the orientation information 40 of the storage unit 150 to Control the display as follows.

As described above, since the screen update frequency of the menu application program is set in the first screen update frequency information F1, the screen update frequency indicated by the first screen update frequency information F1 is “15”. Therefore, in this example, the content of the moving image player is displayed on the first display 110, and the content of the menu application (menu image) is displayed on the second display 120 (step S11). Therefore, it is possible to suppress flickering of the moving image reproduced by the moving image player and display it easily to the user.

  When the process of step S10 or S11 is completed, the application execution unit 164 determines whether the current state or orientation of the mobile phone 100 has changed or a user operation has been performed (step S12). If there is no change in the current state and orientation of the mobile phone 100 and no user operation is performed (step S12: NO), the application execution unit 164 performs the process of step S12 again.

  In addition, when an operation for ending the application program being executed is performed (step S12: end operation), the application execution unit 164 ends the execution of the application program related to the end operation. Then, the application execution unit 164 determines the first and second application information (A1, A2) as follows depending on which application is indicated by the first and second application information (A1, A2). ), The first and second screen update frequency information (F1, F2) is updated (steps S13 to S15).

  That is, when the application program indicated by the first application information A1 is completed (step S13: A1), the application execution unit 164 updates the first application information A1 in the storage unit 150 with the second application information A2, and the first screen The update frequency information F1 is updated with the second screen update frequency information F2. In addition, the application execution unit 164 initializes the second application information A2 and the second screen update frequency information F2 with “0” (step S14). On the other hand, when the application program indicated by the second application information A2 is terminated (step S13: A2), the application execution unit 164 initializes the second application information A2 and the second screen update frequency information F2 with “0” ( Step S15). When the process of step S14 or S15 is completed, the control unit 160 performs the process again from step S2 of FIG.

In addition, in step S12, the application execution unit 164 changes the current state or orientation of the mobile phone 100, or the performed user operation is other than an operation for terminating the application program (step S12). : Change, other operations), the control unit 160 performs the processing from step S9 again.
Here, for example, the orientation of the mobile phone 100 is the orientation shown in FIG. 3A, and the content of the video player is displayed on the first display 110 as in the above example, and the content of the menu application (menu image). Is displayed on the second display 120. In this case, it is assumed that the orientation of the mobile phone 100 has changed to the orientation shown in FIG. 4A (step S12: change, other operation). Then, the display control unit 165 continues to display the content of the video player on the first display 110 and the menu image on the second display 120 so that the top direction (upper part) of the content of the video player and the menu image is on the microphone 5 side. (Step S9: YES, S11). As described above, even when the mobile phone 100 performs display so that the orientation of the mobile device matches the top and bottom of each content, the content of the video player is continuously displayed on the first display 110, so flicker is suppressed. It can be displayed for easy viewing by the user.
