Image transmission system, image receiving device, and control method for image receiving device

An image receiving device which receives image information from an image transmitting device starting wireless communication when coupled to an image supply device and which outputs the image information to an image display device, the image receiving device comprising:

• a wireless communication unit receiving the image information transmitted from the image transmitting device;
• a first output unit outputting the image information received by the wireless communication unit to the image display device;
• a second output unit outputting a control signal controlling a power of the image display device to the image display device;
• and
• a control unit detecting a state of the wireless communication by the image transmitting device, the control unit is configured to input and output control information to and from the image display device via the first output unit and the second output unit, wherein the control information includes controlling the power of the image display device, and wherein
• the control unit outputs a first control signal from the second output unit directly to the image display device for the image display device to turn on its own power, when detecting that the wireless communication requesting to transmit image information is started, and
• the control unit outputs a second control signal turning off the power of the image display device from the second output unit to the image display device, when detecting that the wireless communication is disconnected.

A control method for an image receiving device which receives image information from an image transmitting device starting wireless communication when coupled to an image supply device and which outputs the image information to an image display device, the control method comprising:

• outputting the image information received by a wireless communication unit to the image display device by a first output unit of the image receiving device;
• outputting a signal controlling a power of the image display device to the image display device by a second output unit of the image receiving device;
• detecting a state of the wireless communication by the image transmitting device;
• outputting a first control signal from the second output unit directly to the image display device for the image display device to turn on its own power, when detecting that the wireless communication requesting to transmit image information is started;
• receiving the image information transmitted from the image transmitting device;
• outputting the received image information to the image display device;
• and
• outputting a second control signal from the second output unit to the image display device turning off the power of the image display device, when detecting that the wireless communication is disconnected.
