Wide dynamic range image sensor

摘要: The present invention relates to a CMOS image sensor having wide dynamic range, which permits favorable imaging even in cases where bright portion and dark exist simultaneously. range can be widened by preventing the saturation of optical charge at high illuminance removing low signals due long-time accumulation, intermediate short-time ultra-short time accumulation from pixel portions sensor. Further, adaptive control also performed dynamically changing conditions that comprise combination different times each plurality short signals.
