Abstract

In night vision applications, because the light reflected by a target is very weak, the image captured by the Low-Light- Level camera has a great deal of noise attached on it. To remove such noise, the image must be processed in time. In this paper a real-time image processing system with a high- speed DSP device embedded in is constructed. The system employs an Analog Front End (AFE) device as the analog video digitalizer, and a DA converter with video synthesizing function in the analog video output channel. The whole processing board is small in size, and easy in use.
