Abstract
A focal plane staring sensor is provided that includes an M×N sensor, where M is a number of rows of sensor pixels in the sensor and N is a number of columns of sensor pixels in the sensor, where M and N are integers greater than one. A control circuit samples a sensor pixel value for each sensor pixel of the M×N sensor at a plurality of different integration times corresponding to an amount of time that a photonic charge can be acquired in each sensor pixel of the M×N sensor, wherein the control circuit selects one sample from a set of samples to generate a scaled value to facilitate an equalization of a signal to noise ratio between the sensor pixels.
