| Abstract: | According to the character of the reset noise of CCD video signal,this paper introduced the technology of correlated double sampling(CDS),analyzed and researched the method of selecting sample location of the CDS by using analog to digital converter.The result showed that using the sample location selected by this method to do CDS could release the effect of the reset noise,and improve the Signal-to-Noise. |
