A method and apparatus to reduce undesirable deficiencies in an image produc ed by a microbolometer array including multiple smaller arrays includes applyin g a separate bias pulse to each of the microbolometers in the smaller arrays a nd measuring a resulting signal corresponding to the applied bias pulse for eac h of the microbolometers using multiple measurement circuits associated with t he smaller arrays during the frame time. Further, one or more known bias pulses are applied to the measurement circuitry during the frame time, one or more resulting calibration signals are measured, an offset parameter for each of the smaller arrays based on the corresponding measured resulting calibration signals is computed, and the measured resulting signal is corrected using th e associated computed offset parameter to produce an output signal that reduce s the undesirable deficiencies in the image produced by the array.
