Abstract
The accumulating frames characteristics of CCD camera as a night-vision detector was studied. Utilizing CCD external trigger, computer video capture card and image processing software, the image accumulation was made. The detection of the static object image whose illuminance on the CCD FPA (focal plane array) is less than 3.7×10-5 Lux is realized and the image's resolution of 300 TV lines is achieved. This experimental system can provide a kind of night-vision device capable of detecting the static object at low-light level and with low cost compared to an image intensifier.
