By the way, the database 26 stores animation video data related to the other party in association with the telephone number of each other party who is supposed to have a television call with the terminal. This animation video data is used as substitute video data to be displayed instead of the reception video data coming from the terminal device of the communication partner. FIG. 2 shows an example of the animation video data stored in the database 26.

The main control unit 23A is composed of a microprocessor, and includes a selection display control function 231 as a control function according to the present invention, in addition to a normal control function such as connection control of a wireless channel and communication control after a communication link is established. It has.

When a call using the television telephone function is started, the selection display control function 231 reads animation video data associated with the other party from the database 26 and receives this animation video data from the other party terminal. It is displayed on the LCD 32 in place of the video data of the called party. When the user inputs a display switching instruction at the key input unit (KEY) 35 during a call, the display video data is switched from the animation video data to the other party video data received from the other party in response to this instruction. Thereafter, similarly, the user operates the key input unit (K
EY) Every time a display switching instruction is input in 35, the display video data is alternately switched between the receiving video data and the animation video data.

Next, the operation of the communication terminal device configured as described above will be described according to the control procedure of the main control unit 23A.
FIG. 3 is a flowchart showing a control procedure of the main control unit 23A and its contents.

In the standby state, the main control unit 23A monitors the arrival of the incoming call and the outgoing call operation. In this state, it is assumed that the user of his / her own terminal device has performed a calling operation to make a telephone call with an arbitrary party using the videophone function. Then, the main control unit 23A detects this transmission operation in step 3a and shifts to step 3b, where the connection control is executed. Then, when a communication link is established with the communication partner terminal device by this connection control, the process proceeds from step 3c to step 3e to start the call control.

At this time, the main control section 23A reads out the animation video data corresponding to the call partner from the database 26 in step 3d. And
This animation video data is supplied to the LCD control unit 27 instead of the reception video data coming from the terminal device of the other party. For this reason, the above-mentioned animation image is displayed on the LCD 32 together with its own transmission image instead of the image data received from the other party.

For example, if the call partner is "090-1234-567"
8 "is read out, the animation video data M shown in FIG.
D32 is displayed. FIG. 4A shows an example of the display result. Therefore, the user can make a call using the videophone function in the same posture as usual without displaying the face image of the other party.

On the other hand, during the call, the main controller 23A monitors the input of the display switching instruction and the operation of ending the call in steps 3f and 3i, respectively. In this state, it is assumed that the user of the terminal device inputs a display switching instruction by pressing a predetermined key on the key input unit 35.

Then, the main control unit 23A executes step 3
The process shifts from step f to step 3g, where the display switching control is performed. That is, in this case, instead of the currently displayed animation video data M, the received video data of the communication partner decoded and reproduced by the multimedia processing unit 25 is selected, and the LCD control unit 27 is displayed to display the received video data. Give instructions. As a result, the received video sent from the other party is displayed on the LCD 32 instead of the animation video that has been displayed so far. FIG. 4B shows an example of the display result. Therefore, the user can check the face image of the other party during the call as needed.

Thereafter, similarly, every time the user inputs a display switching instruction through the key input section 35, the main control section 23A shifts from step 3f to step 3g, where the LCD
The display image at 32 is alternately switched between the image received from the other party and the animation image read from the database 26.

When an animation image is displayed as a display image, the main control unit 23A generates a message indicating that the received image is not displayed in step 3h, and adds this message to the control data or the transmission image data. Alternatively, the information may be transmitted together with the information and displayed on the terminal device of the other party.

Finally, when the call ends, the main controller 23A
Moves from step 3i to step 3j, executes the control for disconnecting the communication link, and returns to the standby state.

As described above, in the first embodiment, animation video data that associates a call partner with each call partner is stored in advance in the database 26 as a substitute image. The animation video stored in the database 26 is replaced by the LCD 32 instead of the video of the other party received from the other party terminal.
And the display video is alternately switched between the animation video and the video received from the other party each time the user inputs a display switching instruction at the key input unit 35 during a call. .

Therefore, when the speaker arbitrarily inputs a display switching instruction during a call, the speaker can select a desired one of the face image of the partner speaker and the animation image stored in the database 26 in advance. Images can be selectively displayed. For this reason, when it is not necessary to display the image of the other speaker due to the other speaker or the call time zone, etc., it is possible to make a call while displaying the animation image, thereby reducing the stress felt by the speaker. be able to. At this time, the speaker does not look away from the LCD 32, so that the other speaker does not feel uncomfortable. On the other hand, when it is necessary to confirm the face of the other speaker, the received face image of the other speaker can be displayed as it is by inputting a display switching instruction. For this reason, a call using the videophone function can be performed as needed.

Further, in this embodiment, when an animation image is displayed, a message indicating that the received image is not displayed is added to or included in the control data or transmission image data and transmitted to the terminal device of the other party. I try to make it. For this reason, it is not necessary for the speaker of the other party to correct his or her posture in order to transmit his / her own image, and the television call can be performed in a comfortable posture.
