N2 - We propose a method for improving image resolution. The method consists of an interpolation and a sharpening process. We research about some interpolations for producing high resolution images and show the properties of the interpolations in the frequency domain. Based on the research, we selected Lanczos function for the interpolation and applied the sharpening method which uses weighted sum of cubic operations of the pixel differences to the interpolated image. Experimental results also show that the sharpening with Lanczos interpolation gives clear high resolution images.
