Further, in this PDC / PHS, videophones implemented in a wired telephone network such as ISDN, that is, still image / moving image communication has been put into practical use. A composite mobile communication device (hereinafter, appropriately referred to as a composite mobile phone) that performs such voice communication and character / image communication displays an image on a liquid crystal display unit in order to display image information of a still image or a moving image in an easy-to-see manner. Is desired to be expanded.
【0003】
Hereinafter, a conventional mobile phone will be described with reference to the drawings. FIG. 10 is a perspective view showing an external configuration of a mobile phone capable of communicating character information, and FIG. 11 is a perspective view showing an external configuration of another mobile phone capable of communicating character information. Further, FIG. 12 is a perspective view showing an external configuration of another mobile phone capable of communicating character information.

Further, the radio unit 63 performs frequency conversion and power amplification for transmitting a radio signal through the transmission / reception antenna 37 at the time of transmission.
【0058】
Further, the modulation / demodulator 64 performs demodulation at the time of reception and modulation at the time of transmission of the QPSK signal or the like. The demodulated received signal consists of voice-related data, communication protocol-related data, and image-related data. The voice processing unit 65 performs codec processing for decoding the received voice-related data and encoding the voice signal to be transmitted. The received signal from the voice processing unit 65 is converted into a voice signal and output from the speaker 35. Further, the voice signal from the microphone 36 is input to the voice processing unit 65 and converted into voice-related data.
【0059】
Further, the control unit 67 controls each unit of the composite mobile phone, executes communication procedure processing according to the applicable communication protocol, and in particular, executes display mode control corresponding to the present invention described later as a display control means. .. Further, the control unit 67 outputs an incoming call drive signal to the light emitting diode 39, and makes an incoming call by blinking the light emitting diode 39. The control unit 67 outputs an incoming ring tone signal to the speaker 35 (ringer). Further, a battery 41 is connected to the control unit 67, and its voltage (remaining battery level) is monitored.

Further, the image signal captured by the CCD camera 40 is input to the image processing unit 70, and for example, band compression coding processing at the time of transmission is performed and converted into image-related data. Further, the received image-related data is subjected to band expansion decoding processing at the time of reception in the image processing unit 70, and is converted into an image signal suitable for the signal form to be displayed on the liquid crystal display unit 34. As a result, the captured image-related data can be transmitted, or the received image-related data can be output to the liquid crystal display unit 34 to display the image.
【0061】
Next, the display mode control corresponding to the present invention will be described. The display mode control includes (A) display control (first display setting) during a voice call with the slide operation unit 31 closed or in the standby state of character / image communication, and (B) the character with the slide operation unit 31 opened. / This is to switch the display control (second display setting) during image communication.
【0062】
The control unit 67 takes in input operation signals of the key operation unit 32 in the slide operation unit 31, for example, input operation signals such as power on / off, telephone number input, on / off hook, etc., and depending on the state of the slide operation unit 31. The above-mentioned controls (A) and (B) are executed. To execute the controls (A) and (B), the slide open / close detection unit 71 detects the connection state of the plug connector units 48, 49 and the receptacle connectors 51, 52 shown in FIG. 3 by opening and closing the slide operation unit 31. , The control unit 67 takes in the detected connection state and identifies the open / closed state of the slide operation unit 31.
【0063】
When the control unit 67 recognizes the closed state as shown in FIG. 2, that is, the standby state during a voice call or character / image communication, the control unit 67 recognizes the open / closed state. Set to voice call / standby mode as the first display setting of (A). In this case, information required for voice call or communication standby (antenna mark of received electric field strength shown in Fig. 2, battery capacity display, destination name "" and its telephone number "090-1234-5678", time, etc. ) Is displayed on the screen of the liquid crystal display unit 34 through the image processing unit 70 only in a part of the area that can be visually recognized from the screen viewing window 33.
