Abstract
Resolution of any image taken by CCD camera is generally lower in resolution in comparison with original object.
Assuming the imaging system as diffraction limited - the major component responsible for this resolution limitation is
the pixel geometry in CCD. The area, shape of pixel and distance between them (inter-pixel spacing) together contributes
in reduction of the resolution of the final electronic image. A number of techniques have been reported in the literature to
overcome this geometric resolution limitation. We have proposed a novel geometric superresolution technique in which a
CCD-mask is displaced over CCD-plane by one pixel in subpixel steps - both in x and y directions. The resultant
processed superresolved image is improved in resolution by the subpixel steps factor. Simulation results in 2D have been
presented which shows improvement in resolution. This superresolution technique can be applied to microscopy, medical
imaging, satellite imaging and astronomy.
