IMAGE TRANSMITTING/RECEIVING SYSTEM, IMAGE TRANSMITTING APPARATUS, RECEIVED IMAGE DISPLAYING APPARATUS, WIRELESS CONTROL APPARATUS, AND IMAGE TRANSMITTING/RECEIVING METHOD

摘要

A received image displaying apparatus comprises: a wireless communication unit that wirelessly receives the frame images transmitted by the image transmitting apparatus with which the received image displaying apparatus has established a connection of wireless communication; and a displaying unit that displays the frame images, which were wirelessly received by the wireless communication unit, in an order in which the frame images were captured. At least one of the image transmitting apparatus and the received image displaying apparatus comprises: a reference sync signal generating unit that generates the reference sync signals; and a control unit that, if the wireless communication unit has received no reference sync signals for a certain time interval, controls the reference sync signal generating unit to generate reference sync signals and that further controls the wireless communication unit to wirelessly transmit the reference sync signals to the other apparatus included in the image transmitting/receiving system.

主权项

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 the image transmitting apparatus to wirelessly communicate with the received image displaying apparatus serving as a transmission destination of the frame image and 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; and a control unit that controls the reference synchronization signal generation unit to generate the reference synchronization signal and controls the wireless communication unit to wirelessly transmit the reference synchronization signal to another apparatus included in the image transmitting/receiving system when the wireless communication unit does not receive the reference synchronization signal within a constant period.
