Real-time video displaying technique for LLL digital image accumulation

摘要

A novel real-time video display technique for low-light- level (LLL) digital image accumulation is advanced in this paper. Low signal to noise ratio is the main characteristic of LLL imaging system, and noise is the key reason for LLL image degradation. Traditionally, LLL image accumulation technique has been known as the most important technique for LLL TV image enhancing. But with the accumulating time prolonging, the video displaying frame time becomes longer. This surely cause twinkle sense of vision. In this paper, a novel parallel algorithm and architecture is put forward to implement real-time video display for LLL digital image accumulation. By adopting this processing method, not only the real-time display technique is achieved, but also the LLL image quality is improved greatly.
