Examples in digital graphics

A screenshot of a Microsoft Windows XP application displaying a visual artifact. This was fixed in the next release, Windows Vista .

Occurrences in video entertainment

Many people who use their computers as a hobby experience artifacting due to a hardware malfunction. The cases can differ but the usual causes are:

  • Fan issues, such as failure of cooling fan.
  • Unsuited video card drivers.
  • Drivers that have values that the graphics card is not suited with.
  • Overclocking beyond the capabilities of the particular video card.

The differing cases of visual artifacting can also differ between scheduled task(s).

In microscopy

In microscopy, an artifact is an apparent structural detail that is caused by the processing of the specimen and is thus not a legitimate feature of the specimen.

For example, a crush artifact is artificial elongation and distortion when smearing cells or tissue for microscopy.[1]
