Abstract:
1. An imaging sensor system comprising: at least one image sensor having a plurality of detectors defining a sensor array, each detector configured to provide an output signal representative of a sensed image; and an equalization system configured to receive respective output signals from the detectors; estimate a distribution for at least one detector based on the respective output signals; compare the distribution of the at least one detector to a given distribution to determine a mapping function for the at least one detector; and apply the respective mapping function of the at least one detector to the output signal of the at least one detector to provide an equalized signal for the at least one detector; wherein the equalization system is configured to estimate a distribution for at least a second detector based on the respective output signals; determine a mapping function for the at least second detector; and apply the respective mapping function of the at least second detector to the output signal of the at least second detector to provide an equalized signal for the at least second detector; and wherein the mapping function for the at least second detector is determined using the formula: wherein d
