Abstract: A system and method is provided for performing high dynamic range digital double sampling. More particularly, a CMOS image sensor is provided that includes a pixel array with each pixel sampling both dark and bright values for digital double sampling. After the sampled signals are digitized, a mean dark value is determined and each dark value is further fed to a lookup table that generates an output value taking into account whether the pixel has been saturated. In over exposed conditions, the lookup table will generate a negative value output to eliminate image artifacts. All three values are fed to adder logic circuit that subtracts the mean dark value and the lookup table output from the bright value. This resulting output is fed to a video viewer.
