Abstract£ºBased on the balance principle of static electric field£¬ a new algorithm for image resolution enhancement is proposed£¬where the interpolation function is adjusted automatically by the electrical potential differences of the adjoining pixels or/and energy zones to obtain selfª²adapted magnify color images£¬and the effects of all color vectors in the image interpolation are considered instead of a single interpolation function in the conventional algorithms to avoid the disadvantages£¬such as marginal vagueness£¬distortion and distinct artifacts£¬color distortion£®The experimental results show that the images processed with the interpolation algorithm have better quality than those in the traditional ways and keep clear margin and contour information£¬especially for remote sensing image£¬medical system£¬and public security official system£®
