Abstract: An information transmission method and a system capable of transmitting information without requiring a troublesome operation and at a low cost is provided. A portable communication terminal such as a cellular phone, a PHS or the like capable of making a telephone call and performing communications over a telephone line changes an image to be displayed on a display portion with time to transmit information to an information-receiving device. The information-receiving device receives a change in display of the image on the portable communication terminal by a receiver portion and recognizes the information from the received change in display (e.g., a display interval, etc.).
