Imaging using offsetting accumulations

摘要

An imaging system includes a sensor array of sensor elements and plural accumulator sets of accumulators. Switches alternatively route detections from a respective sensor element to different accumulators of the respective accumulator set. Offset devices offset an amount read out from a first accumulator of a set by an amount read out from a second accumulator of that set.

1. An imaging system comprising:
a sensor array of sensor elements; plural accumulator sets, each of said accumulator sets including plural accumulators, each of said accumulators being configured to accumulate detections; switches to partition detections from a respective sensor element into detection sets and to route each detection set to at most one accumulator of the respective accumulator set so that said different accumulators respectively accumulate different respective detections; and offset devices, said offset devices including circuitry, each offset device being to read out accumulations from said accumulators and to offset an amount read out from a first accumulator of a set by an amount read out from a second accumulator of that set.
