It does, however, result in image file sizes that are larger than necessary, and some image processing tools are not designed to handle excessive amounts of oversampling. While it is better to be slightly oversampled than slightly undersampled, if that choice exists, excessively oversampled ...

In the sections below, the right side of the edge and the entire image are subjected to a variety of signal processing steps: blurring (similar to what might be expected from poor quality or out of focus lenses), sharpening, and combinations of the two (similar to real-world conditions, ...
