Abstract :
A high-density CMOS image sensor has a normal mode and three signal-processing function modes: wide dynamic-range mode, motion-detection mode, and edge-extraction mode. Small pixel and real-time operation are achieved by using a four-transistor pixel scheme and column-parallel on-chip analog operation.
