<p><P>PROBLEM TO BE SOLVED: To provide a wireless camera system capable of efficiently utilizing limited frequency bands to the maximum and performing flexible operation. <P>SOLUTION: A receiver (radio receiving device) has a transmission processing unit for providing a radio signal defining a radio frequency band and transmission frequency for each radio transmission signal to a plurality of cameras (radio transmitting devices) No C1 to C5, and a reception processing unit of the control signal thereof is provided on the camera. The frequency band and the center frequency of a radio transmission signal can be changed according to an inputted control signal by each camera. As the result, output channels (Ch1-Ch5) of a receiver for assigning a wide band channel and a narrow band channel can be arbitrarily changed. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
