Abstract
A method of processing a digital input image having a plurality of scan lines of pixel data into an interpolated digital output image by interpolating the pixel data in each scan line of the digital input image and replicating the pixel data in the slow scan direction to provide a plurality of scan lines interpolated in the fast scan direction, calculating slow scan direction interpolation coefficients for scan lines to be interpolated in the interpolated output image, storing the interpolated scan lines using the storage typically used for the display image, interpolating selected scan lines which have been stored using selected existing scan lines to produce scan lines interpolated in the slow scan direction of the interpolated output image, and writing scan lines interpolated in the slow scan direction in place of scan lines selected for interpolation in the output image.
