ABSTRACT:
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 in a given pixel is low. The accumulated number of reset skips in a given time frame, together with the standard analog output, is used to calculate the sensor high DR output signal. A signal processing system is used to simultaneously process both sensor analog and digital outputs.
