Abstract

Three kinds of artifacts unique to digital images are illustrated: aliasing caused by undersampling; interference phenomena caused by improper display of images; and harmonic overtones caused by quantization of amplitudes. Especial attention is given to undersampling when the sample size and interval is the same. This situation is important because it is typical of solid-state cameras.
