Speckle masking is a triple correlation method that can reconstruct diffraction-limited images from astronomical speckle interferograms. The obtained resolution is about 30 times higher than the resolution of conventional astronomical photography. In this paper we describe a photon-counting version of speckle masking that can be applied to speckle interferograms consisting of a small number of photon events. We show computer simulations which illustrate the feasibility of the method. Finally, we compare photon-counting speckle masking with four-dimensional bispectrum processing, tomographic speckle masking, cross-triple correlation processing and bispectrum processing of photon-counting speckle interferograms.
