  Further, when the panel-type mobile phone 1 is used, the foldable mobile phone 1 is not exposed to the display panel 6 that has been moved to a predetermined displacement position with respect to the operation unit 8 and is not exposed to the operation keys. By assigning various commands such as channel switching commands and volume adjustment commands for digital terrestrial television broadcasting, the display image can be switched even when the operation unit housing 4 and the display unit housing 3 are positioned on the left and right and are held by both hands. In addition, various commands for operating the folding mobile phone 1 can be inputted without any trouble.

(2) Circuit Configuration Next, the circuit configuration of the mobile phone 1 will be described with reference to FIG.

The cellular phone 1 stores, in a CPU (Central Processing Unit) 40, various programs such as basic programs and application programs, and various data such as phone book data (Read ROM).
Only Memory) 41, RAM (Random Access Memory) 42 used as a work area of the CPU 40, operation unit 8, displacement state detection unit 43 for detecting the displacement state of the display panel 6, and display for controlling the display direction of the display panel 6. A control unit 44, a wireless communication transmitting / receiving unit 45, a television broadcast receiving unit 46, a codec unit 47, and a video / audio processing unit 48 are connected.

  Then, the CPU 40 appropriately loads various programs from the ROM 41 in response to a call instruction such as a call instruction or an end instruction input via the operation unit 8 and a program viewing instruction such as a channel switching instruction or a volume adjustment instruction. These are read out, developed in the RAM 42 and executed, thereby controlling each circuit unit of the foldable mobile phone 1 and executing various processes in accordance with a call instruction and a program viewing instruction.

  In practice, in the call mode, the CPU 40 compresses and encodes a voice signal obtained by collecting the user's voice with the microphone 9 by the codec unit 47, and a wireless communication transmitting / receiving unit 45 for the encoded data obtained as a result. Then, after performing predetermined transmission processing such as modulation processing, the data is transmitted to the base station via the radio communication antenna 49.

  At this time, the CPU 40 receives a reception signal corresponding to the other party's voice transmitted from the base station by the wireless communication antenna 49 and loads the reception signal into the wireless communication transmission / reception unit 45, and the wireless communication transmission / reception unit 45 receives the reception signal. The demodulated data obtained as a result of performing predetermined reception processing such as demodulation processing is decoded by the codec unit 47 to obtain an audio signal, which is output via the audio output unit 51 including the speaker 7 and the earphone terminal 10. .

  Thereby, the CPU 40 is adapted to establish a call between the user and the other party.

  On the other hand, when a program viewing start command for digital terrestrial television broadcasting is input via the operation unit 8, the CPU 40 shifts to the program viewing mode accordingly.

  At this time, the CPU 40 controls the television broadcast receiving unit 46 in accordance with the channel number of the channel designated by the user via the operation unit 8, and the displacement state detection unit 43 detects the displacement state of the display panel 6. The display control unit 44 and the video / audio processing unit 48 are controlled accordingly.

  As a result, the television broadcast receiving unit 46 first selects a television broadcast signal of a channel designated by the user from a plurality of channels of television broadcast signals received by the television broadcast receiving antenna 50, and performs predetermined processing such as demodulation processing. In this way, digital data composed of a transport stream that has been generated in accordance with, for example, the MPEG (Moving Picture Experts Group) standard is regenerated and sent to the video / audio processing unit 48.

  The video / audio processing unit 48 separates the digital data regenerated by the television broadcast receiving unit 46 into compressed video data and compressed audio data, and decodes the compressed video data and the compressed audio data, respectively, thereby program video. Data and program audio data are generated.

  Here, the display panel 6 is selected so that the entire horizontally long portable broadcast program video for digital terrestrial television broadcasting can be displayed as it is when the size of the display screen is horizontal when viewed from the user when the panel displacement is used. ing.

  Therefore, the video / audio processing unit 48 detects the program video based on the program video data when the displacement state detection unit 43 detects that the display panel 6 is stored in the storage recess 21 (that is, during normal use). The reduced conversion video data is generated by reducing the entire program video so that the width of the program video matches the width of the display panel 6.

  The video / audio processing unit 48 converts the reduced conversion video data from digital to analog, sends the obtained reduced conversion video signal to the display panel 6 as it is via the display control unit 44, and converts the program audio data from digital to analog. Then, the obtained program audio signal is sent to the audio output unit 51.

  Thus, during normal use, the CPU 40 displays the reduced converted video based on the reduced converted video signal on the display panel 6 so that the width of the reduced converted video matches the width of the display panel 6 and the program audio based on the program audio signal. Is output from the speaker 7 or the earphone of the audio output unit 51, and the reduced conversion video is displayed on the vertically long display panel 6 when viewed from the user in a state where the display unit housing 3 and the operation unit housing 4 are positioned vertically. Can be displayed so that characters, graphics, etc. do not turn upside down or landscape.

  When the displacement state detection unit 43 detects that the display panel 6 has been displaced to a predetermined displacement position (that is, when the panel displacement is used), the video / audio processing unit 48 converts the program video data into digital / analog as it is. The obtained program video signal is sent to the display control unit 44, and the program video signal is rotated by 90 degrees parallel to the front of the panel of the display panel 6, and the obtained rotated program video signal is displayed on the display panel. 6, the program audio data is converted from digital to analog, and the obtained program audio signal is sent to the audio output unit 51.

  Thus, when the panel displacement is used, the CPU 40 displays the rotated program video based on the rotated program video signal on the display panel 6 by matching the width of the rotated program video with the length of the display panel 6 in the longitudinal direction, and the program audio signal. Is output from the speaker 7 or the earphone of the audio output unit 51, and the display panel 6 that is horizontally long when viewed from the user in a state where the operation unit casing 4 and the display unit casing 3 are positioned and held on the left and right. In addition, it is possible to watch the program by displaying the rotated program video so that the characters, figures, etc. are not upside down or sideways.

  In this manner, the CPU 40 arranges the display panel 6 with a desired program of digital terrestrial television broadcasting (vertical or horizontal arrangement) for the user regardless of whether the normal use or the panel displacement is used. Can be shown correctly.
