MULTI-CHANNEL IMAGE SIGNAL CAPTURE SYSTEM AND MULTI-CHANNEL IMAGE SIGNAL CAPTURE METHOD WITH IMPROVED CAPTURE EFFICIENCY ACCOMPLISHED BY ACCURATE DETERMINATION ON UNSTABLE PERIOD

摘要

PURPOSE: A multi-channel image signal capture system and a multi-channel image signal capture method are provided to achieve improved image signal capture ratio by accurately determining the unstable period and maximizing the ratio of capture enabled video data. CONSTITUTION: A multi-channel image signal capture system(100) comprises a receiving module(110) for receiving image signals including video data from one or more cameras; a synchronous signal separator module(120) for separating synchronous signals representing the position of the video data from the image signals; an image capture module(130) for capturing first and second image signals in a predetermined capture order; a storing module(140) for storing the separated synchronous signal and information regarding the unstable period of the image capture module; and a determination module(150) for selecting the synchronous signal of the second image signal existing in the section other than the unstable period, based on the synchronous signal extracted from the first image signal and the unstable period.
