Abstract: A new method of restoring suppressed field of digital image space based on the correction operator recovery of spatial frequency spectra. With the proposed method significantly expands the range of values of field reduced through the implementation of the mechanism of decrease in the images of the aperture point spread function, which is a residual and inherent to modern methods of suppressing it.

Keywords: digital image space, spatial-frequency spectrum, point spread function, deconvolution, generalized gradient operator, functional comparison.
