I've been combing through the posts and dictionaries, but haven't found the answer yet. The question is not about different spellings as have been asked previously, but on the semantic meaning of the word used in the errors occurring in the context of image processing, visualisation, produced by graphics cards.
Artifacts (also artefacts) are usually depicted to be man-made objects having some form of art associated with them. They seem to be created intentionally, with a purpose by some author(s).
The question that bothers me is why in video, graphics-card, and image-processing industry errors, side-effects, distortions (noise, screen tearing, etc.) are also called (visual) artifacts.
The jargon "visual artifacts" don't seem to fit under the definition, because they almost refer to the opposite of what an artifact should be.
Does anyone know how, why and when people started referring to unintended, unintentional errors and distortions as artifacts?
