In this paper the problem of restoration of defocused images corrupted by mixed noise is considered. To enhance the noise immunity of restoration algorithm based on iterative method with adaptive regularization and parametric constrains on the solution the prefiltering is proposed to be carried out. To avoid double images blurring on the prefiltering stage the simultaneous suppresion of gaussian and impulse noises is performed according to the local image structure using adaptive nonlinear filter.
