Abstract: PURPOSE: A multi-channel image signal capture method with an improved AGC(Automatic Gain Control) function and a system therefor are provided to perform the AGC function without degrading a capture speed(frame rate). CONSTITUTION: A multiplexer(301) receives a plurality of analog image signals from a plurality of channels, and selectively outputs the received analog image signals. A reference signal calculating unit(302) measures a level of the analog image signal corresponding to each channel, determines an amplification rate necessary for outputting a certain target level from the measured level, and stores a digital reference signal value corresponding to the amplification rate according to channels. A digital/analog converting unit(303) retrieves a digital reference signal value corresponding to a channel determined according to a certain capture sequence among the stored digital reference signal values, and generates an analog reference signal corresponding to the retrieved digital reference signal value. An image signal capture unit(304) amplifies the analog image signal inputted from the multiplexer(301), and converts the amplified analog image signal into a digital image signal.

Abstract: PURPOSE: A multi-channel image signal capturing method and system is provided to extract synchronizing signals of image signals according to channels to decide an optimum capture sequence, and to capture the multi-channel image signals by the capture sequence, thereby increasing the number of captured frames per second. CONSTITUTION: A multiplexer(310) receives a plurality of image signals from a plurality of channels, and selectively outputs the plurality of image signals. An image synchronizing signal separator(320) extracts synchronizing signals from the plurality of image signals. A synchronizing signal storage(330) stores according to channels the relative start time of the synchronizing signals corresponding to each channel and the cycle of the synchronizing signals corresponding to each channel in association with the relative start time, on the basis of a synchronizing signal of one of the plurality of image signals. A capture sequence decider(340) decides the capture sequence of the plurality of image signals, based on the relative start time and the cycle. An image capture unit(350) captures the plurality image signals sequentially in accordance with the decided capture sequence.
