Can be displayed at a glance, as compared with the case of displaying a telephone number or a name in characters, so that the other party can confirm who is before the call.

Further, since it is possible to transmit contents that are difficult to explain only by voice as an image during a call, and to give an oral explanation while referring to each other, complicated meetings and the like can be completed by telephone. It becomes possible.

Further, compared with the case of using a videophone, the transmission data is extremely small, and no special equipment is required, so that the cost is very low. While the mobile phone is a mobile phone, the mobile communication terminal of the present invention is excellent in terms of portability.

Further, if an image such as a logo, a symbol mark, a commercial, etc. of the company to which the user belongs is transmitted in addition to the photograph of the user's own face, a portrait, and a map, the partner can quickly recognize who he or she is. It can be expected to have the effect of giving the other person a stronger impression of himself or his / her company, relaxing the alertness of the other party, or relaxing the place. In addition,
The received face photograph or the like may be registered in the address book or the like on the receiving side in association with the address on the transmitting side.

(Embodiment 2) In Embodiment 1 described above, an image is transmitted during a call (after the start of a call). However, audio data cannot be transmitted during transmission of still image data. If the transmission and reception of images takes time, the time during which the conversation is interrupted becomes longer. Therefore, as in the second embodiment described below, the still image data may be transmitted prior to the start of the call. Further, the operator on the receiving side may receive the storage medium storing the still image data from the operator on the transmitting side, and store the still image data in the mobile communication terminal in advance.
