Patent ID: 7511764

Claim:
A synchronization system for a plurality of video cameras comprising: a base unit, including: a master time-base adapted to generate a master synchronization signal defining a frame period within which a frame of video data is captured; a base unit communications transceiver adapted to transmit the frame synchronization signal; and a video camera, including: a video camera communications transceiver adapted to receive the frame synchronization signal from the base unit and transmit video data to the base unit; a camera time-base adapted to reset a camera time-base value in response to reception of the frame synchronization signal and wherein the camera time-base is configured to operate during a camera time-base period following said reset wherein the camera time-base period is less than the frame period; an image sensor adapted to store video data; and an exposure controller adapted to monitor a value of the camera time-base and, upon detecting the value of the camera time-base matching a predetermined value, initiate exposure of the image sensor.
