When the call connection processing is performed, step ST
At 707, a voice call is made. Step ST7
In 07, the conversion unit 108 converts the analog audio signal from the microphone 105 into a digital audio signal, the audio processing unit 109 encodes the digital audio signal, and supplies the encoded audio signal to the control unit 103. The voice signal is transmitted to the other party's telephone via the transmission / reception wireless unit 102 and the antenna 101.

In step ST707, the transmission / reception radio section 102 receives the voice signal from the telephone of the other party through the antenna 101, gives the received signal to the control section 103, and the control section 103 receives the voice signal. Is given to the voice processing unit 109, and the voice processing unit 109 decodes the voice signal and gives it to the revival 107 via the conversion unit 108. Therefore, in this state, the telephone set 100 can perform a so-called voice call using only the voice with the telephone set of the other party using the microphone 105 and the receiver 107.

Next, the operation when the telephone 100 receives an incoming call will be described with reference to FIG.

As shown in FIG. 8, when the telephone of the other party makes a call and the telephone 100 receives the incoming call, the off-hook key 205 is operated (step ST80).
1) In next step ST802, control section 103 determines whether or not the incoming call is a videophone call.

As a result of the judgment in step ST802,
If it is determined that the incoming call is a videophone call,
In the next step ST803, the incoming call processing as a videophone is performed and the camera unit 110 and the image storage unit 113 are processed.
Etc. to the operating state and call connection processing is performed (step S
T804). When call connection processing is performed (step ST8
04), and a state where a videophone call can be performed is set (step ST805).

In step ST805, the transmission / reception radio unit 102 receives the transmission signal in which the image signal and the voice signal from the other party's telephone are multiplexed via the antenna 101, and gives the reception signal to the control unit 103 to give the control unit. 103 separates the received signal into an image signal and a sound signal, gives the image signal to the image codec unit 111, and gives the sound signal to the sound processing unit 109.

In step ST808, the converter 108 converts the analog voice signal from the microphone 105 into a digital voice signal, and the voice processor 109 encodes the digital voice signal to control the controller 1.
03, the control unit 103 transmits a voice signal to the transmission / reception wireless unit 1
02 and the antenna 101 to the other party's telephone. Therefore, in this state, the telephone set 100 can perform a so-called voice call using only the voice with the telephone set of the other party using the microphone 105 and the receiver 107.

In the above description of the operation of the above-described embodiment, the receiver 107 operates in the case of a voice call and the speaker 106 operates in the case of a videophone call. It is configured so that it can be arbitrarily switched after the call state is established.

That is, in the above embodiment, the off-hook key 205 is used in the so-called receiver call state (step ST901) in which the receiver 107 is in the operating state as shown in FIG. 9 regardless of the voice call or the videophone call. Is continuously operated for a predetermined time or longer (long-pressing operation) (step ST902), the control unit 103 detects this operation signal, and the control unit 103 stops the operation of the receiver 107 and replaces it with the speaker. 1
06 becomes an operation state, that is, a so-called speaker call state (step ST903). And in this state,
Further, the sensitivity of the microphone 105 is controlled under the control of the control unit 103 so as to be increased to the sensitivity required for hands-free communication (step ST904).

As shown in FIG. 10, in a so-called speaker call state (step ST1001) in which the speaker 106 is in an operating state, the off-hook key 205 is continuously operated (long press operation) for a predetermined time or more. Then (step ST1002), the control unit 103 detects the signal of this operation, the control unit 103 stops the operation of the speaker 106, and instead puts the receiver 107 into the operating state, so-called receiver communication state (step ST10).
03). Then, in that state, the control unit 103
The sensitivity of the microphone 105 is reduced to the sensitivity required for receiver communication (step ST1004).

In the above-described embodiment, the image signal from the camera section 110 or the image storage section 1 is operated by the operation of the camera key 204 in the outgoing or incoming call operation of the videophone.
The image signal stored in 13 is selected. However, it is also possible to arbitrarily switch these image signals during a videophone call. Hereinafter, the operation when arbitrarily switching the image signal will be described with reference to FIGS. 11 and 12.

As shown in FIG. 11, in the videophone call according to the present embodiment, the image signal from the camera unit 110 is transmitted (camera image transmission state: step ST1101). In this case, when the camera key 204 is continuously pressed for a predetermined time or more (step ST1102), the control unit 103 detects this operation signal, and the control unit 103 causes the camera unit 11 to operate.
The transmission of the image signal from 0 is stopped, and instead of this, the image signal stored in the image storage unit 113 is transmitted, that is, the substitute image is transmitted (transmission state of the substitute image: step ST1103).

Further, as shown in FIG. 12, the image storage unit 1
It is assumed that the image signal stored in 13 is in a state of being transmitted (transmission state of alternative image: step ST1201). In this case, when the camera key 204 is pressed for a short time (step ST1202), the control unit 103 detects this operation signal, and the control unit 103 stores an image such as an illustration image stored in the image storage unit 113. A state in which signal transmission is stopped and a captured image signal from the camera unit 110 is transmitted instead of the signal transmission (camera image transmission state: step ST
1203).

In this embodiment, the image signal is stored in the image storage unit 113 as it is, but it is also possible to encode and store the image signal in advance. In this case, it is not necessary to re-encode the image codec unit 111 at the time of transmission, and the image can be directly transmitted via the control unit 103. Then, in this case, when the image signal to be transmitted is displayed on the display unit 112 in advance, it is necessary to decode the image signal before displaying.

Further, in the telephone 100 according to the present embodiment, the operation input unit 104 is set to the standby mode in which the camera key is operated by operating the function key 202, and the still image is operated by operating the camera key 204.
