atelieraskart.com/DigitalGlossary01.htm
An unwanted visual element in a digital photograph that is caused by the sensor, optics or imaging algorithms of a digital camera, or by the compression format used to save an image. Common artifacts include jaggies (jagged lines), moiré patterns (an optical illusion that produces a strobing effect), noise (grainy images), and chromatic aberrations (coloured halos around objects).

Any visible feature or distortion in a recorded image or output image that is not present in the corresponding imaged object or input image. Image artifacts can be introduced inadvertently by hardware or software, or intently by an operator. The latter type includes annotation or other direct alteration of an image in order to clarify or call attention to some particular image content. Artifacts introduced by hardware and software generally degrade an image, and, if severe enough, can impair interpretation.
