  FIG. 4 is a flowchart for explaining an example of processing when displaying the display screen information displayed on the display unit 120 of the smartphone 100 on the display unit 217 of the tablet device 200 in the configuration shown in FIGS. is there. FIG. 5 is a diagram for explaining an example of processing when displaying the display screen information displayed on the display unit 120 of the smartphone 100 on the display unit 217 of the tablet device 200 in the configuration illustrated in FIGS. 1 to 3. is there.

  When the connection process between the smartphone 100 and the tablet device 200 is completed (step 1), first, the display screen information A displayed on the display unit 120 of the smartphone 100 is displayed on the tablet device 200 via the external interface units 116 and 214. At that time, the CPU 210 determines whether or not there is a horizontal screen layout for the horizontally long screen in the acquired display screen information A (step 2).

  If there is no horizontal screen layout, the CPU 210 and the display control unit 216 rotate the acquired display screen information A by 90 degrees leftward, and the vertical and horizontal aspect ratios are set to the same ratio. The image is enlarged and displayed on the entire screen (step 3).

  In addition, the CPU 210 converts the tilt indicating the downward direction of the tablet device 200 by rotating it 90 degrees to the left according to the direction of gravity, and recognizes the horizontally long direction as the vertical direction for the acceleration detected by the acceleration sensor 221. (Step 4).

Will be recognized as.

  If there is a horizontal screen layout, the CPU 210 and the display control unit 216 use the acquired horizontal screen layout to enlarge and display the display screen information A over the screen of the display unit 217 of the tablet device 200. (Step 5).

(Other embodiments)
In the tablet device 200, the display screen information acquired from the smartphone 100 is rotated by 90 degrees, and a setting is made as to whether to enlarge and display the entire screen of the display unit 217 with the same aspect ratio. If set, the display screen information acquired from the smartphone 100 may be centered on the display unit 217 without being rotated by 90 degrees. At that time, the process of converting the tilt indicating the downward direction of the tablet device 200 by rotating it by 90 degrees is not performed.

  FIG. 6 is a view for explaining another example of processing when displaying the display screen information displayed on the display unit 120 of the smartphone 100 on the display unit 217 of the tablet device 200 in the configuration shown in FIGS. It is a flowchart.

  When the connection process between the smartphone 100 and the tablet device 200 is completed (step 11), first, display screen information displayed on the display unit 120 of the smartphone 100 is acquired by the tablet device 200 via the external interface units 116 and 214. However, at that time, the CPU 210 determines whether or not there is a horizontal screen layout for the horizontally long screen with respect to the acquired display screen information (step 12).

  If there is no layout for the horizontal screen, the CPU 210 may rotate the display screen information acquired from the smartphone 100 by 90 degrees to enlarge and display the entire screen of the display unit 217 with the same aspect ratio. With reference to the setting, it is determined whether or not “enlarged display” is set (step 13). Note that the display screen information acquired from the smartphone 100 is set in advance via the key input unit 215 to set whether to rotate the display screen 90 degrees and enlarge and display the entire screen of the display unit 217 with the same aspect ratio. The CPU 210 refers to this designation.

  When the above setting is set to “enlarged display”, the CPU 210 and the display control unit 216 rotate the acquired display screen information 90 degrees to the left and set the aspect ratio of the tablet device 200 to the same ratio. The display is enlarged and displayed on the full screen of the display unit 217 (step 14).

  In addition, the CPU 210 converts the tilt indicating the downward direction of the tablet device 200 by rotating it 90 degrees to the left according to the direction of gravity, and recognizes the horizontally long direction as the vertical direction for the acceleration detected by the acceleration sensor 221. (Step 15). When the tablet device 200 is operated in a horizontally held state, the inclination indicating the downward direction of the tablet device 200 is not converted, and the acceleration detected by the acceleration sensor 221 is set to the direction orthogonal to the horizontal direction in the vertical direction. Will be recognized as.

  If there is a horizontal screen layout, the CPU 210 and the display control unit 216 use the acquired horizontal screen layout to enlarge and display the display screen information to fill the screen of the display unit 217 of the tablet device 200 ( Step 16).

  If the above setting is set to “Do not display enlarged”, the display screen information acquired from the smartphone 100 is centered and displayed on the display unit 217 without being rotated 90 degrees (step 17).

  In this way, when the smartphone 100 that has a vertically long screen and is operated in a vertically held state is connected to the tablet device 200 that has a horizontally long screen and is operated in a horizontally held state, the display of the smartphone 100 is displayed. The display screen information of the vertical screen layout displayed on the unit 120 is rotated 90 degrees, and the display unit 120 of the smartphone 100 is enlarged and displayed on the full screen of the display unit 217 of the tablet device 200 with the same aspect ratio. Even when there is no horizontal screen layout in the display screen information displayed on the screen, the vertical screen layout can be enlarged and displayed on the tablet device 200.

  At this time, the tablet device 200 is in a state of being held horizontally to vertically held, but the tilt indicating the downward direction of the tablet device 200 is also converted by rotating it by 90 degrees according to the direction of gravity, for example, an acceleration sensor. Even when a game or application using 221 is used, it can be used based on the fact that the tablet device 200 is held vertically.

  In the above-described embodiment, the display screen information of the vertical screen layout displayed on the display unit 120 of the smartphone 100 is rotated 90 degrees to the left, but the rotation direction of 90 degrees is the right direction. It may be set arbitrarily to either one. However, even in that case, it is necessary to make the rotation direction the same when the inclination indicating the downward direction of the tablet device 200 is converted.

  In addition, the display screen information of the vertical screen layout displayed on the display unit 120 of the smartphone 100 is not limited to the enlarged display of the display unit 217 of the tablet device 200, and the screen resolution of the smartphone 100 and the tablet device 200 are also displayed. The display screen information of the vertical screen layout displayed on the display unit 120 of the smartphone 100 is enlarged with the same aspect ratio in the vertical and horizontal aspect ratios in the layout frame corresponding to the horizontal screen of the tablet device 200. As long as it can be displayed. For example, when the screen resolution of the smartphone 100 is 800 × 480 and the screen resolution of the tablet device 200 is 1024 × 600, the display is reduced in the process of not displaying the enlarged image. Further, when the screen resolution of the smartphone 100 is 800 × 480 and the resolution of the tablet device 200 is 1920 × 1080, the centering display is performed by enlarging to a double angle of 1600 × 960 in the enlargement display process. become. That is, the display screen information of the layout for the vertical screen displayed on the display unit 120 of the smartphone 100 is not displayed in an enlarged manner on the entire screen of the display unit 217 of the tablet device 200. “In the case of“ enlarging ”, it is possible to display the image without changing the aspect ratio, and in the case of“ enlarging ”, it is also possible to display the image in the layout frame without changing the aspect ratio.
