Abstract
Provided is an image processing apparatus for correcting an influence of atmospheric turbulence by using pieces of image data captured temporally successively. It includes: an obtaining unit that obtains pieces of partial image data corresponding to images of a processing target area in the pieces of image data; a transform unit that transforms the obtained pieces of partial image data into Fourier spectra; an estimation unit that estimates a phase containing a high-frequency component by using phases of low-frequency components in the Fourier spectra; a correction unit that, on the basis of the result of the estimation and reference data determined on the basis of the obtained pieces of partial image data, corrects the result of the estimation on at least one of the pieces of partial image data; and a generation unit that generates output image data corresponding to the pieces of image data on the basis of the corrected result.
