Electronic Shutter Introduction

  Electronic Shutter, one of the main features of CCD CCTV cameras is an signal processing. At low light conditions, the CCD is able to gather signal at the electronic shutter speed of full 1/60th per second. Under bright lighting conditions, the video processing chip automatically responds by reading the CCD and immediately “early purging” it in order to precisely control the video level. Even at a shutter speed of 1/100,000th per second, the CCD camera can deliver 60 images per second, but each image is gathered at a much shorter period of time. The image is continually monitored and optimized by signal processing circuit. At last, we an get an excellent picture, without any fiddling, no adjustments, what’s more, unbelievable reliability.
