An imaging system and method for correcting for differences between correlated double sampling (CDS) circuits (150) of a row of CDS circuits of an imager of the imaging system (100). A plurality of gain correction coefficients having an initial value and a plurality of dc offset correction coefficients having an initial value are stored. A reference dc offset value and a reference gain value are determined (303), and a dc offset value and a gain value for each CDS circuit is determined. The dc offset value and gain value for each CDS circuit is compared to the reference dc offset value and reference gain value, respectively, and the plurality of gain correction coefficients and the plurality of dc offset correction coefficients is updated in accordance with the comparisons. |
