Abstract
After the charge coupled device (CCD) noise sources is expatiated, the methods of restraining the main CCD noise are analyzed. For the shot noise, the wavelet theory and adaptive theory are combined and the error formula is derived in a sufficient sampling frequency. The working principle of CDS technology and its impact on filtering the CCD reset noise are discussed. The results show that as long as the choice of appropriate sampling time, the reset noise can be restrained furthest.
