A high Dynamic Range Active Pixel CMOS image sensor architecture has incorporated therein an adaptive pixel reset. The individual sensor pixels are reset only when accumulated charge, or the integration time exceeds certain predetermined limits. The reset is skipped when the integrated charge signal...http://www.google.com/patents/US7079178?utm_source=gb-gplus-sharePatent US7079178 - High dynamic range active pixel CMOS image sensor and data processing system incorporating adaptive pixel reset
