ABSTRACT:
In a method, a plurality of scale factors and a plurality of sets of pixel replication sequences are provided. A scale factor, a pixel replication sequence, a first pixel of an original image, and a scale offset parameter are selected. The selected first pixel is mapped into a first pixel location in an enlarged image. The selected scale factor and scale offset are added, producing a first sum. The first sum is compared to a maximum sum. If the first sum is less than the maximum sum, the selected first pixel is also mapped into a second pixel location. Otherwise, a second pixel is selected from the original image and mapped into the second pixel location.
