Single-chip video camera with multiple integrated functions

Lower-cost and power of CMOS photo sensors can be taken advantage of only if CMOS sensors achieve similar image quality as CCDs provide for consumer purposes. An image sensor system design takes non-optimized CMOS sensors, implemented in standard CMOS processes, and uses digital signal processing for signal correction and digital computing for image enhancement. This b/w CMOS camera with active pixel cells offers a maximum resolution of 720 pixels per line at 576 lines. A window can be programmed for areas of the image to be tracked for focused exposure measurement.
