In order to carry out information transmission/reception intuitively and easily, a black-and-white pattern of a symbol representative of data of an image is switched every scan timing of one frame of a display unit and is displayed continuously only during a period displaying whole data of the image. In an information processing terminal, the data of the image is acquired in accordance with the symbol read by a reader/writer. To the contrary, in a case of transmitting data from the information processing terminal to a display apparatus, a symbol representative of data to be transmitted is output from the reader/writer to be read by a read area formed at a predetermined position of the display unit. In the display apparatus, data is acquired in accordance with the read symbol. The present invention may be applied to various information processing apparatuses including a personal computer, PDA, a television receiver.
