Abstract This paper deals with the technology of forming adaptive filters to eliminate distortions such as defocus on images recorded using mobile devices. The main purpose of the development is to ensure a sufficiently high quality of the distortion correction with minimal computational costs. The blind parametric identification of the model with a radially symmetric quadratic-exponential frequency response is used to adjust the filter parameters. The algorithm, the pseudo-code of the program and the results of experiments demonstrating the effectiveness of the proposed approach are given.
