<P>PROBLEM TO BE SOLVED: To provide a radio communication device and a radio communication method capable of making a data communication with an external device even when a battery residual capacity is small, and to provide a radio communication program. <P>SOLUTION: A digital camera 1 which is radio-connected to a printer 2 having a battery 209 and has a battery 109 receives information of a battery residual capacity b of the battery 209 and an electric wave, which are transmitted from the printer 2, (steps S506 and S507) and compares the battery residual capacity b of the battery 209 with a battery residual capacity a of the battery 109 (step S509) and generates induction power on the basis of the received electric wave in the case that the battery residual capacity a of the battery 109 is lower than the battery residual capacity b of the battery 209, and communicates data with the printer 2 on the basis of the generated induction power (steps S510 and S512). <P>COPYRIGHT: (C)2007,JPO&INPIT |
