Next, the control unit 3 turns on the TV tuner 2 and sets the reception channel in the TV tuner 2 in response to the activation of the TV function from the user operation (step S103 in FIG. 2). Subsequently, the control unit 3 performs a rotation angle detection process (step S104 in FIG. 2).

  The rotation angle detection process is performed according to the flowchart of FIG. That is, the control unit 3 first acquires the rotation angle of the housing from the rotation sensor unit 6 (step S202 in FIG. 3). As shown in FIG. 5A, the rotation angle of the housing and the display direction to be described later are set to the display direction “1” at a rotation angle of 0 degrees when the display unit 7 is in a vertically long state above the operation unit 10.

If the rotation angle is 90 degrees (step S204 in FIG. 3), the rotation angle setting is set to 90 degrees (step S209 in FIG. 3), and the process ends. If the rotation angle is 180 degrees (step S205 in FIG. 3), the rotation angle setting is set to 180 degrees (step S210 in FIG. 3), and the process ends. If the rotation angle is 270 degrees (step S206 in FIG. 3), the rotation angle setting is set to 270 degrees (step S211 in FIG. 3), and the process ends. If the rotation angle does not apply to any of the above angles, the rotation angle is set to 0 degree (step S207 in FIG. 3), and the rotation angle detection process is terminated.

  Next, the control unit 3 performs TV image display processing using the rotation angle set in the rotation angle detection processing in step S104 described with reference to FIG. 3 (step S105 in FIG. 2). The TV image display process in step S105 is performed according to the flowchart of FIG. That is, in the TV image display process, the control unit 3 acquires the rotation angle setting set in the rotation angle detection process (step S302 in FIG. 4), and the display size and the rotation angle are 180 degrees depending on the acquired rotation angle. When the angle is 270 degrees, the display direction is reversed. Therefore, the display direction for displaying in the forward direction is set even when the angle is 180 degrees or 270 degrees.

  That is, when the acquired rotation angle is 0 degree (step S303 in FIG. 4), the control unit 3 sets the display direction to “1” as shown in FIG. 5A, and displays the entire image. The size is set to vertical: aaa dots and horizontal: bbb dots (step S307 in FIG. 4), the size of the TV image input from the TV tuner 2 is adjusted (step S310 in FIG. 4), and the size-adjusted image Is transferred to the display control unit 5 and the process is terminated (step S311 in FIG. 4).

  When the acquired rotation angle is 90 degrees (step S304 in FIG. 4), the control unit 3 sets the display direction to “2” as shown in FIG. : Ccc dots, horizontal: ddd dots are set to be horizontally long (step S308 in FIG. 4), the size of the TV image input from the TV tuner 2 is adjusted (step S310 in FIG. 4), and the size-adjusted image is displayed and controlled. The transfer process is terminated to the unit 5 (step S311 in FIG. 4).

  When the acquired rotation angle is 180 degrees (step S305 in FIG. 4), the control unit 3 sets the display direction to “3” as shown in FIG. 5D, and rotates the display size of the entire image. The vertical length is set to vertical: aaa dots and horizontal: bbb dots as when the angle is 0 degree (step S309 in FIG. 4), and the size of the TV image input from the TV tuner 2 is adjusted (step S310 in FIG. 4). ) The size-adjusted image is transferred to the display control unit 5 and the process is terminated (step S311 in FIG. 4).

  When the controller 3 determines that the acquired rotation angle is not any of the above 0 degrees, 90 degrees, and 180 degrees (steps S303, S304, and S305 in FIG. 4), the acquired rotation angle is 270 degrees. As shown in FIG. 5B, the display direction is set to “4”, and the display size of the entire image is the same as when the rotation angle is 90 degrees. Horizontal: ccc dots, horizontal: ddd dots (Step S306 in FIG. 4), the size of the TV image input from the TV tuner 2 is adjusted (step S310 in FIG. 4), the size-adjusted image is passed to the display control unit 5 and the process is terminated (FIG. 4). 4 step S311).

  Returning to FIG. 2 again, when the TV image processing in step S105 described with reference to FIG. 4 is completed, the control unit 3 sets the display direction setting value set in the TV image processing in step S105 by the display processing unit 5. The display direction is changed in accordance with the display image, and the size-adjusted image is supplied to the display unit 7 through the display control unit 5 (step S106 in FIG. 2), and the display unit 7 displays the TV image (step S107 in FIG. 2). . Therefore, in the present embodiment, the TV image size is automatically adjusted and the display direction is set according to the rotation angle of the housing, and the display unit 7 is optimally displayed. Further, since the display direction is automatically switched, the display direction switching operation by the user can be made unnecessary, and the trouble of switching can be released.

  Further, during the above TV image display, when the control unit 3 determines that the user inputs a selection to end the TV function from the operation unit 10 (Yes in step S108 in FIG. 2), the TV tuner 2 is turned off, etc. Is completed (step S109 in FIG. 2), and the TV function is terminated (step S110 in FIG. 2). When the user operation is not the end of the TV function (No in step S108 in FIG. 2), the rotation angle detection process is performed again (step S104 in FIG. 2), and the process is continued.

  Next, another embodiment of the present invention will be described. Another embodiment of the present invention is characterized in that the basic configuration of the mobile terminal is the same as that in FIG. 1, but the operation by the control unit 3 is executed by the flowcharts shown in FIGS. 6 and 7.

  That is, in the standby display of the mobile phone, the control unit 3 determines whether or not the rotation angle detection is set when there is a rotation detection operation input by the user from the operation unit 10 (step S402 in FIG. 6). (Step S403 in FIG. 6). When the rotation detection process is set, the rotation angle detection process is performed (step S404 in FIG. 6). Since this rotation angle detection process is the same as the process according to the flowchart of FIG. 3 described above, description thereof is omitted.

  Next, when the rotation angle detection process ends, the control unit 3 performs a display control process based on the rotation angle set in the rotation angle detection process (step S405 in FIG. 6). This display control process is executed by the control unit 3 in accordance with the flowchart of FIG. That is, in the display control process, the control unit 3 first acquires the rotation angle set in the rotation angle detection process in step S404 (step S502 in FIG. 7).

  Subsequently, the control unit 3 sets a display character size and a display direction according to the acquired rotation angle. When the acquired rotation angle is 0 degree (step S503 in FIG. 7), the display direction is set to “1” as shown in FIG. 5A, and the display character size is set to “normal” ( Step S507 in FIG. 7), the display character size and the display direction are adjusted (Step S510 in FIG. 7), the display data whose size has been adjusted is passed to the display control unit 5 and the process is terminated (Step S511 in FIG. 7).

  If the acquired rotation angle is 90 degrees (step S504 in FIG. 7), the control unit 3 sets the display direction to “2” and the display character size to “enlarge” as shown in FIG. 5C. Is set (step S508 in FIG. 7), the display character size and the display direction are adjusted (step S510 in FIG. 7), and the display data whose size has been adjusted is passed to the display control unit 5 to complete the processing (step in FIG. 7). S511).

  When the acquired rotation angle is 180 degrees (step S503 in FIG. 7), the control unit 3 sets the display direction to “3” and sets the display character size to “normal” (step S507 in FIG. 7). Then, the display character size and the display direction are adjusted (step S510 in FIG. 7), and the display data whose size has been adjusted is passed to the display control unit 5 to complete the processing (step S511 in FIG. 7).

  Further, when the control unit 3 determines that the acquired rotation angle is not any of the above 0 degrees, 90 degrees, and 180 degrees (steps S503, S504, and S505 in FIG. 7), the acquired rotation angle is 270 degrees. As shown in FIG. 5B, the display direction is set to “4”, the display character size is set to “enlarged” (step S506 in FIG. 7), and the display character size and the display direction are set. Adjustment is performed (step S510 in FIG. 7), and the display data whose size has been adjusted is passed to the display control unit 5 to complete the processing (step S511 in FIG. 7).

  Returning to FIG. 6 again, when the display control process in step S405 ends, the control unit 3 continues to display the display processing unit 5 in FIG. 1 according to the display direction and display character size set in the display control process. Is controlled to set the display direction and is displayed by the display unit 7 (step S406 in FIG. 6).

  As described above, in this embodiment, the rotation angle of the housing is detected, and the display direction and the display character size are set. Therefore, when the display unit such as a mobile terminal is small, it is difficult to see characters. This can be eliminated and the effect that the display unit can be used effectively is obtained. In addition, even when switching the character size, switching by user operation such as a button is troublesome, but since the character size and display direction can be changed simply by rotating the housing, an effect of reducing the burden of user operation can be obtained. It is done.
