Term: Artifact (defect)

General term to describe a broad range of undesirable flaws or distortions in digital reproductions produced during capture or data processing. Some common forms of image artifacts include noise, chromatic aberration, blooming, interpolation, and imperfections created by compression, among others. In digital sound recordings, the effect of lossy compression is often cited as accounting for audible artifacts, although several other types of artifacts may also be present.
