数字式可编程微光电视图像实时处理系统

Digital Programmable Real-Time tow light Level TV System

简要回顾了传统的微光电视系统的发展及像增强器的性能。对微光图像作数字处理可改善对比度，抑制噪声，进一步提高图像质量。随着大量高速DSP芯片的出现，对微光电视图像进行数字化处理己成为可能。分析了微光电视图像的特点及实时数字图像处理算法，在此基础上提出并实现了一种多DSP并行的微光电视图像实时处理系统。

Low Light Level TV(LLLTV) as an important night vision instrUment, is becoming moreand more useful in the military field. Traditional system relies mostly on the image intensitier. Imageintensifier can enhance global brightness. But the noise is aversion and the contrast is not very Well.Digital procession of image is helpful to enhance image qualities and to eliminate noise. With thedevelopment of digital signal proassor(DSP),it has borne possible to process LLLTV images withdigital methods. In this paper, characterisics of LLLTV images and real-time algorithms are analyzed.A parallel real-time LLLTV system is also introduced.
