Abstract
We report an image processing method which is able to break the diffraction limit for single frame images. If an image is taken by diffraction limited optical system with regularly spaced pixel detector, and if the spacing of pixels of the detector is much small than the diffraction pattern, then the spatial resolution of the image can be increased beyond the diffraction limit by using a method known as nearestneighbor- pixel-deconvolution (NNPD). Initial experiment result has proved feasibility of this method. Two images captured from outer space were processed using this method, with some new features unveiled in the processed images.
