Claim:
1. A wireless control apparatus in an image transmitting/receiving system that comprises: a plurality of image transmitting apparatuses each of which continuously wirelessly transmits continuously captured frame images in a captured order; a plurality of received image displaying apparatuses each of which continuously wirelessly receives the frame images continuously wirelessly transmitted by the plurality of image transmitting apparatuses and continuously displays the received frame images in the captured order; and the wireless control apparatus that instructs an image transmitting apparatus in the plurality of image transmitting apparatuses, to wirelessly communicate with a received image displaying apparatus in the plurality of received image displaying apparatuses, serving as a transmission destination of a frame image or instructs the received image displaying apparatus to wirelessly communicate with the image transmitting apparatus serving as a transmission source of the frame image, the wireless control apparatus comprising: a wireless communication unit that wirelessly communicates with the image transmitting apparatus and the received image displaying apparatus; a reference synchronization signal generation unit that generates a reference synchronization signal; a control unit that determines whether or not the wireless communication unit has received the reference synchronization signal within a predetermined period and controls the wireless communication unit to wirelessly transmit the reference synchronization signal to both the image transmitting apparatus and the received image displaying apparatus included in the image transmitting/receiving system if the control unit determines that the wireless communication unit has not received the reference synchronization signal within the predetermined period; an instruction receiving unit that receives an instruction for addition, modification, and deletion of a combination of the received image displaying apparatus and the image transmitting apparatus; a disconnection instruction control unit that controls the wireless communication unit to transmit an instruction for starting a disconnection process of wireless communication to the image transmitting apparatus or the received image displaying apparatus of the combination received in the instruction receiving unit when the instruction receiving unit receives the instruction; and a blanking interval recognition unit that recognizes a vertical blanking interval of the frame image, wherein the control unit controls the wireless communication unit to transmit the reference synchronization signal within the vertical blanking interval.
