Abstract
A method and apparatus for magnifying a portion of a digital image on a display screen in either of two ways. The first method includes a two pass scheme, where each of the passes represents an interpolation in x and y direction respectively, cubic interpolation in each direction is approximated using a one dimensional convolution filter followed by linear interpolation. The second method uses a two dimensional convolution filter first, followed by bilinear interpolation. All of the procedures that are used are accelerated using a hardware package which facilitates exceptionally fast execution.
