Abstract
A method for the improvement of resolution in an observed solar image is pr oposed. A blind deconvolution method is used for restoration of an atmosphe rically-degraded solar image, and a super-resolution method is applied to i ts restored image to improve the resolution. It is confirmed that a blind d econvolution process can restore fine structures that are blurred in an obs erved image, and that the super-resolution process can make a cutoff freque ncy in a blind-deconvolved image higher. A time series of super-resolved im ages of a sunspot observed with the 70-cm Vacuum Tower Telescope at Teide O bservatory is presented.
