A complicated grid pattern is insufficiently processed by a smartphone camera. A scan of a drawing with large areas of whitespace; the diamond Moiré pattern is a scanning artifact. Digital artifact in information science, is any undesired or unintended alteration in data introduced in a digital process by an involved technique and/or technology.
Compression artifacts in compressed audio typically show up as ringing, pre-echo, "birdie artifacts", drop-outs, rattling, warbling, metallic ringing, an underwater feeling, hissing, or "graininess". An example of compression artifacts in audio is applause in a relatively highly compressed audio file (e.g. 96 kbit/sec MP3).
An example of bloom in a picture taken with a camera. Note the blue fringe that is particularly noticeable along the right edge of the window. Bloom (sometimes referred to as light bloom or glow) is a computer graphics effect used in video games, demos, and high-dynamic-range rendering (HDRR) to reproduce an imaging artifact of real-world ...
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 [ edit ]

It is this difference that can result in motion artifacts. The MPEG-2 standard allows for an alternate interlaced sampling scheme, where 4:2:0 is applied to each field (not both fields at once). This solves the problem of motion artifacts, reduces the vertical chroma resolution by half, and can introduce comb-like artifacts in the image. Original.
During video motion, screen tearing creates a torn look as the edges of objects (such as a wall or a tree) fail to line up. Tearing can occur with most common display technologies and video cards and is most noticeable in horizontally-moving visuals, such as in slow camera pans in a movie or classic side-scrolling video games.
The backscatter of the camera's flash by motes of dust causes unfocused orb-shaped photographic artifacts. In photography , backscatter (also called near-camera reflection [ 1 ] ) is an optical phenomenon resulting in typically circular artifacts on an image, due to the camera's flash being reflected from unfocused motes of dust , water ...
