Visual artifact
anomalies during visual representation of e.g. digital graphics and imagery
Visual artifacts (also artefacts) are anomalies apparent during visual representation as in digital graphics and other forms of imagery, especially photography and microscopy.
In digital graphics
Image quality factors, different types of visual artifacts
Compression artifacts
Digital artifacts, visual artifacts resulting from digital image processing
Noise
Screen-door effect, also known as fixed-pattern noise (FPN), a visual artifact of digital projection technology
Ghosting (television)
Screen burn-in
Distortion
Silk screen effect
Rainbow effect
Screen tearing
Moiré pattern
Color banding
In video entertainment
Many people who use their computers as a hobby experience artifacting due to a hardware or software malfunction. The cases can differ but the usual causes are:
Temperature issues, such as failure of cooling fan.
Unsuited video card (graphics card) drivers.
Drivers that have values that the graphics card is not suited with.
Overclocking beyond the capabilities of the particular video card.
Software bugs in the application or operating system.
The differing cases of visual artifacting can also differ between scheduled task(s).
In photography
These effects can occur in both analog and digital photography.
Chromatic aberration due to optical dispersion through a lens, leading to color fringes at high-contrast boundaries in a photograph
Purple fringing
Motion blur
Near-camera reflection, visual artifacts caused by the backscatter of light by unfocused particles
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.
“Visual artifact” enters the record as anomalies during visual representation of e.g. digital graphics and imagery. Crown Archives preserves that source wording while asking what Visual, artifact and anomalies can confirm, complicate or overturn.
Why this record matters
“Visual artifact” is worth following because a concise public description often conceals a longer documentary argument. Here, Visual, artifact and anomalies provides the most credible route into that argument.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jan 11, 2026. The linked authority identifier is Q7936582. None of the 0 selected statements returned an explicit reference.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
