The photon statistics of a particular photon-imaging detector are studied, and the conditional probability of photon counts in the output given a certain number of counts in an associated reference channel is derived. This result is applied in a variable level discrimination technique which significantly reduces detection errors approaching the ideal limit. These results can be applied to other photon-limited detectors with nonideal pulse height distributions.
