Abstract
A controller for scaling an input image is provided. The controller selects a pixel neighborhood that includes a plurality of pixels neighboring a pixel. The controller compares at least part of the pixel neighborhood to a pattern. If the pattern is present in the pixel neighborhood, the controller applies a scaling algorithm to at least a portion of the pixel neighborhood in order to obtain a scaled image. The controller also selects another pixel neighborhood that includes a plurality of pixels neighboring a pixel in the scaled image, and compares at least part of the another pixel neighborhood to another pixel pattern. If the another pixel pattern is present in the another pixel neighborhood, the controller applies a correction algorithm to at least a portion of the another pixel neighborhood in order to obtain a processed scaled image.
