The report deals with one aspect of restoration of atmospherically degraded images the problem of defining isoplanatic patch size. The general restoration situation is considered to indicate the situation where the concept of isoplanaticism is appropriate. Then a model is considered and some problems of the Fourier transform technique of defining isoplanatic patch are pointed out. If the degraded reference function is not identical with the point response function then singularities in the spectrum of the intensity of the restored image can give rise to negative image functions. A measure for indexing this effect is indicated.
