Super-resolution　image　reconstruction　technique　is　to　restore　a　high-resolution　and　high-quality　image　from　multiple　degraded　low-resolution　observations.　The　POCS　method　for　super-resolution　image　reconstruction　attracts　many　researchers＇　attention.　This　paper　proposes　to　reduce　the　amount　of　Gibbs　artifacts　present　on　the　edges　of　the　high-resolution　image　estimate　obtained　by　the　POCS　method.　The　proposed　method　weights　the　blur　PSF　centered　at　an　edge　pixel　with　an　exponential　function,　so　that　the　modified　PSF　coefficients　decrease　in　the　direction　orthogonal　to　the　edge.　Experimental　results　show　that　the　modification　effectively　reduces　the　visibility　of　the　artifacts　on　the　edges　and　obviously　improves　the　quality　of　the　high-resolution　reconstructed　image.
