摘要

PPROBLEM TO BE SOLVED: To authenticate connection between devices by a simple operation without increasing cost in a radio communication system. PSOLUTION: A digital camera 20 includes a generation part generating a unique pattern for uniquely identifying the digital camera 20, a notification part outputting the unique pattern and a communication part for radio communication. A printer 30 includes an input part receiving input of the unique pattern, an authentication part authenticating connection of the digital camera 20 based on the unique pattern, and a communication part performing radio communication. When the printer 30 authenticates connection of the digital camera 20 based on the unique pattern, radio communication is started. PCOPYRIGHT: (C)2007,JPO&INPIT
