Visual artifact

Visual artifacts are anomalies during visual representation of e.g. digital graphics and imagery.

Examples in digital graphics

• Image quality factors, different types of visual 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
• Distortion
• Silk screen effect
• Rainbow effect
• Screen tearing
• Purple fringing
• Chromatic aberration
• Moiré pattern

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]
