Abstract
A method includes correcting for at least one of gain and offset during frame integration for photodetector events. Gain and offset correction is performed separately in each pixel of a digital read-out integrated circuit (DROIC) for a plurality of corresponding pixels in a photodetector array. First and second binary counters respectively use a gain register and an offset register to implement gain and offset correction.
