The audio codec 68 converts an audio signal from the microphone 20 into a digital signal and performs data compression, and an audio decoder that expands received compressed audio information, converts it into an analog signal, and supplies the analog signal to the speaker 18. Department. The TDMA signal processing circuit 70 arranges information to be transmitted from the voice codec 68 in a predetermined time slot and supplies the information to the modem 72. The TDMA signal processing circuit 70 separates the information of the predetermined time slot from the signal received from the modem 72 and 68. The modem 72 modulates the signal from the TDMA signal processing circuit 70 and supplies it to the RM processing circuit 74, demodulates the signal from the RF processing circuit 74, and demodulates the signal from the TDMA signal processing circuit 70.
To supply. The antenna 10 is connected to the RF processing circuit 74. The RF processing circuit 74 converts an intermediate frequency (IF) signal from the modem 72 into a high frequency (RF) signal having a predetermined frequency and supplies the signal to the antenna 10, and converts the high frequency signal received by the antenna 10 into an intermediate frequency signal. To the modem 72.

First, the operation of transmitting audio data will be described.
When an audio signal is input from the microphone 20, the audio codec 68 converts the output of the micro 20 into a digital signal and compresses the data. The TDMA signal processing circuit 70 subjects the compressed audio data from the audio codec 68 to TDMA processing and supplies the data to the modem 72. In the TDMA system, the same frequency is transmitted to a plurality of radio mobile stations (cellular phones) by time division multiplexing.
It is a method that is shared by. The modem 72 modulates a signal from the TDMA processing circuit 70, and the RF processing circuit 74 converts an intermediate frequency signal from the modem 72 into a high frequency signal and supplies it to the antenna 10. As a result, the audio data is
It is transmitted wirelessly to the communication partner. Information for determining whether the signal is audio data or PIAFS data is added to the signal transmitted from the antenna 10. In this case, since the data is audio data, information indicating the audio data is incorporated.

The operation of voice reception is as follows. It is checked whether or not information indicating a voice signal is added to the signal received by the antenna 10. In the case of an audio signal, the RF processing circuit 74 converts the signal received by the antenna 237 to an intermediate frequency, and the modem 72 demodulates the signal from the RF processing circuit 74. The TDMA signal processing circuit 70 extracts a signal belonging to a predetermined own time slot from a signal from the modem 72 and supplies the extracted signal to the audio codec 68. The audio codec 68 expands the signal from the TDMA signal processing circuit 70, converts the signal into an analog signal, and supplies the analog signal to the speaker 18.
Thereby, the voice from the communication partner is output from the speaker 18.

Next, the operation of transmitting and receiving PIAFS data will be described. For example, an image is taken by the camera unit 30 and the CPU unit 3
It is assumed that image data stored in the flash memory 60 of No. 4 is transmitted as PIAFS data. In this case, the image data read from the flash memory 60 is sent to the TDMA signal processing circuit 70 via the CPUs 52 and 62. The TDMA signal processing circuit 70 supplies the data to the modem 72 after performing the TDMA processing. The modem 72 modulates the signal from the TDMA signal processing circuit 72, and the RF processing circuit 74 converts the signal from the modem 72 from an intermediate frequency to a high frequency and sends the signal from the antenna 10 to space. The transmission data is transmitted to the space in a state where the PIAFS data and identification information for determining the data content are incorporated.

When receiving PIAFS data, the CPU
62 determines that the received signal is PIAFS data, and executes the following processing. That is, the RF processing circuit 74 converts the signal received by the antenna 10 into an intermediate frequency, and the modem 72 demodulates the signal from the RF processing circuit 74 and supplies the demodulated signal to the TDMA signal processing circuit 70. TDMA
The signal processing circuit 70 extracts a predetermined time slot portion from the signal from the modem 72 and supplies it to the CPU 62.

3) The operation of the electronic viewfinder (EVF) for confirming the subject is started (S4).

The image sensor 40 outputs an electric signal corresponding to the optical image of the photographing lens 24 (S5). Image sensor 40
Is a non-interlaced analog signal, but in order to increase the processing speed, it is not a total pixel consisting of 640 × 480 dots but a 320 × 24
The image signal has a size reduced to 0 dots.

The image processing circuit 42 performs predetermined processing such as color balance adjustment, exposure adjustment, correction at the time of strobe shooting, and signal conversion to the YCrCb (4: 2: 2) format on the output signal of the image sensor 40. Apply. CP of CPU unit 34
It is supplied to U52 (S6). The image processing circuit 42 further includes
The output image of the image sensor and E are added to the YCrCb-converted signal.
A process for correcting a shift in the aspect ratio due to a difference in the frequency of the output image to the VF and an endian conversion process are performed (S7).

An NTSC encoder included in the image processing circuit 42 converts the YCrCb signal into an NTSC signal (S
8) An NTSC signal is supplied to the display control circuit of the color liquid crystal panel 22 via the CPU 52 (S9). Thus, the subject image is displayed on the screen of the color liquid crystal display panel 22 (S10).

By continuously looping the processing from S5 to S10 at a cycle of 1/30 seconds, the subject image is always displayed on the EVF.

The processing for storing the photographed image data in the flash memory 60 will be described. When the shutter button 12 is pressed, the CPU 52 JPEG-compresses the output image of the image processing circuit 42 at that time and outputs a JF image including a thumbnail image.
It is stored in the flash memory 60 as an IF file.
At this time, the date and time information and the like stored in the flash memory 60 are read by the CPU 52 and written into the extension area for storing the image property information. In the case of the first image after the power is turned on, information corresponding to the movement history up to that point is recorded. Of course, it is also possible to record only the CS-ID (base station ID) at the time of shooting.
It is also possible to set not to record at all. CS
-ID may of course be converted into specific location information, or may be stored as intermediate code information in the image property information area.

The mode dial 46 is formed using the antenna 10 as an operation axis, and as shown in FIGS. 4 to 6, an execution mode can be selected in accordance with the telescopic position of the antenna 10.

The antenna mode is shifted to the browsing mode by slowly rotating the antenna 90 clockwise as viewed in FIG. 10, and the camera mode is shifted by slowly rotating the antenna 90 counterclockwise. Since the light emitting diode 92 is turned on in the browsing mode and the light emitting diode 94 is turned on in the camera mode, the rotation of the antenna 90 may be stopped when the light emitting diodes 92 and 94 transfer. Also, by quickly rotating the antenna 90, the light emitting diode 96 for power-off / standby and the light emitting diode 92 in the operation mode before it are turned off.
Or 94 lights up. If the antenna 90 is rotated more quickly while the light emitting diode 96 is turned on, the light emitting diode 96 is turned off.

As shown in FIG. 4, when the antenna 90 is pushed into the main body, it is in the power-off mode or the key lock mode. Which mode is set depends on the antenna 90
Depends on the mode before pressing. That is, if the antenna 90 is pushed into the main body while the light emitting diode 96 is lit, the power supply is turned off and the light emitting diode 9 is turned on.
When the antenna 90 is pressed in a state where 6 is turned off, a key lock mode is set.

Also in the case of FIG. 10, the telephone mode is set in a state where the antenna 90 is largely pulled out from the main body as shown in FIG. When you rotate antenna 90 in phone mode,
