In order to improve CCD performance, the noise composition in CCD image is analyzed according to the operating principle of CCD, and CCD noise is categorized. Correspending measures are introduced to deal with different noise. Signal processing schemes of double-correlated sampling,dual slope integration and clamp sample are given to eliminate readout noise in this paper. As a result, the SNR of CCD is improved.
