Abstract
When a communication between a camera and a television is performed utilizing a first wireless communication mode which employs high-directional radio transmission, and a second wireless communication mode which employs low-directional radio transmission with lower directivity than that of high-directional radio transmission, the television detects that the communication in the first wireless communication mode has been disconnected and notifies the camera. The camera determines whether or not the movement of the camera is the cause of disconnection in the first wireless communication mode. If the reason for disconnection is the movement of the camera, a control signal is transmitted to the television so as not to execute the process for an avoiding no-signal condition.
