Abstract :
The noise sources and the characteristics of the low light level (LLL) image are studied, and various existing noise processing techniques are analysed in detail. On the basis of these, a novel real-time adaptive interframe temporal comparison technique is presented. By using this approach, the short-live noise scintillation is reduced significantly, therefore the quality of the LLL image is improved greatly. An analysis and a discussion of the processing results are also given
