Two parallel blind deconvolution methods, each of which uses multiple frames or several images segmented from a single frame, were applied to solar images to reconstruct their fine structure. The influence of low-contrast intensity distribution on the solar images on their reconstruction was investigated with computer simulations. The methods are also applied to an observed solar image.

Key words : blind deconvolution, image reconstruction, solar image, atmosperic turbulence, frame segmentation, stellar speckle interferometry
