Image sensors capable of a non-destructive readout (NDR) allow reading several frames during the integration time without affecting a photo charge being collected in the pixelpsilas well. We show that two published algorithms for processing the sequence of NDR frames into a high dynamic range (HDR) image suffer from ldquostepped gradientrdquo artifacts using data taken with an ldquooff-the-shelfrdquo CMOS image sensor. We present a novel algorithm that is capable of alleviating this image… CONTINUE READING
