METHOD AND SYSTEM FOR CAPTURE OF THE MULTI-CHANNEL IMAGE SIGNAL WHICH CAN ENHANCE THE CAPTURE EFFICIENCY BY DECIDING THE UNSTABLE PERIOD OF THE SYSTEM

摘要

The present invention relates to a system and method for capturing of the multi-channel image signal which can enhance capturing rate of image signals by exactly deciding the unstable period of an image capturing module capturing video data included in an image signal, wherein the system for capturing of the multi-channel image signal according to one embodiment of the present invention comprises a receiving module for receiving image signals including video data from at least one camera; a sync signal separating module for extracting sync signals indicating the existing location of video data from the image signal; an image capturing module for capturing video data of the image signal sequentially according to predetermined capturing order; a storage module for storing information about the unstable period of the image capturing module and the extracted sync signal respectively; and a decision module for selecting the sync signal of the second image signal located outside of the unstable period based on the extracted sync signal from the first image signal and the unstable period; wherein the unstable period includes the first unstable period, the predetermined period from falling edge of the sync signal extracted from the first image signal. According to the present invention, there is an advantage that it is possible to provide a system and a method for capturing of the multi-channel image signal which enhance the capture efficiency of image signals by raising the rate of capturable video data to the maximum through the exact decision of the unstable period of an image capturing module capturing video data of an image signal.
