PROBLEM TO BE SOLVED: To obtain image information that can sufficiently support display of a large-sized image pattern or printing or the like by controlling picked-up image information to be transferable during call connection processing and controlling the image information to be displayable in the case of receiving the image information during the call connection processing. SOLUTION: A program, which is used to compress image information from an operating processing between its call transmission and its reply, to transmit the compressed image information and to expand received image information and to display it, is written in a ROM 15 or an EEPROM 16 and a control section 13 reads the program in the case of call transmission or call reception and uses it for its control. After conducting a call control, a caller side terminal (A) transmits its image transmission capability and a called party terminal (B) transmits its image transmission capability. An optimum image transmission capability is decided on the basis of both the image transmission capabilities and an acknowledgement message is transmitted. |
