ABSTRACT:
Interpolating a low or medium resolution image to a higher resolution image using a pixel replication and averaging technique. An overlay image having pixels of a first display resolution and a plurality of alpha blending values each indicating the degree of blending with a background image is interpolated to the resolution of the background image. In addition to interpolating pixel values, alpha blending values are themselves interpolated and multiplied by corresponding overlay pixel values prior to being blended with the background image.
