Abstract. The comparison of the quality of digital images using various recovery techniques is fulfilled in the work. Even with exactly known apparatus function (with side lobes) of  iterative methods there are considerable difficulties in restoring the image in the largest side lobe larger than or equal to -10 dB relative to the main lobe of the apparatus function. When exactly known hardware features side-lobe level is not an obstacle for image reconstruction by the method of the reference image or Wiener filtering.

Key words:  image restoration, iterative methods, the method of the reference image, the Wiener filter.
