<P>PROBLEM TO BE SOLVED: To provide a wireless endoscopic apparatus, a receiving device thereof, and a receiving method, by which a communication channel with a good communication state is capable of efficiently selected. <P>SOLUTION: A wireless communication circuit unit 404 communicates with a transmitting device using a communication channel selected from among n (n>1) communication channels each having a use frequency band partially overlapping with that of at least one of the other communication channels, and receives image data transmitted from the transmitting device. A ROM 402 stores x (1<x≤n) communication channel groups to which L (1≤L<n) communication channels belong. A control unit 401 selects an arbitrarily defined communication channel group from among the communication channel groups, and detects the usage state of a communication channel belonging to the selected communication channel group. On the basis of the result of the detection, the control unit determines whether or not to perform communication using the communication channel belonging to the selected communication channel group. <P>COPYRIGHT: (C)2011,JPO&INPIT |
