A lag-free 1024*1024 progressive scan interline CCD image sensor with antiblooming and exposure control

A 1024*1024 IL CCD (charge coupled device) image sensor has been developed that incorporates antiblooming and electronic exposure control while eliminating lag and obtaining a high responsivity. The incorporation of the antiblooming structure and electronic exposure control has been achieved without sacrificing other important device characteristics such as lag, smear, photoresponse linearity, and sensitivity. The progressive-scan architecture of this device offers the same resolution in an electronic-camera application as that of a two-million element, interlaced device. A noninterlaced scan with dual-horizontal registers makes it well suited for high-speed, machine vision applications. >
