Abstract
Methods and systems for scaling an input image are provided. A pixel neighborhood that includes a plurality of pixels neighboring a pixel is selected. At least part of the pixel neighborhood is compared directly to a predetermined pattern in order to determine whether the predetermined pattern is present in the pixel neighborhood. A controller applies a predetermined scaling algorithm to at least a portion of the pixel neighborhood in order to obtain a scaled image if the predetermined pattern is present in the pixel neighborhood.
