<P>PROBLEM TO BE SOLVED: To easily suppress occurrence of a screen change. <P>SOLUTION: An information processor 2 switches a display state of an image to be outputted to a predetermined display state, when connection to other devices has been detected by receiving a connection signal but the connection signal has not been re-received just for a predetermined time TA thereafter. An interface unit 1a of a display device 1 receives image data outputted from the information processor 2. A controlling unit 1b of the display device 1 makes the interface unit 1a repeatedly output the connection signal at a cycle TB which is shorter than the predetermined time TA, and every time the connection signal is outputted, the connection to the display device 1 is detected by the information processor 2. <P>COPYRIGHT: (C)2013,JPO&INPIT |
