FIELD: physics, computer engineering.
SUBSTANCE: invention relates to means of processing digital images. The method includes obtaining a series of images of a three-dimensional object with a given scene depth pitch and converting said images into a spatial spectrum using two-dimensional Fourier transform, processing the obtained spatial spectra of images in the series by spatial-frequency filtering, performing coordination of scales of the images in the series, summing the filtered and scaled spatial spectra of the images, performing reconstruction of a sharp image of the object using inverse two-dimensional Fourier transform of the summed spatial spectrum of the image.
EFFECT: obtaining a sharp image of a three-dimensional object with an unlimited depth of field.
