The gray spot in the center is a shadow artifact. 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 ...
A compression artifact (or artefact) is a noticeable distortion of media (including images, audio, and video) caused by the application of lossy compression. Lossy data compression involves discarding some of the media's data so that it becomes small enough to be stored within the desired disk space or transmitted ( streamed ) within the ...
A typical video tearing artifact (simulated image) Screen tearing [1] is a visual artifact in video display where a display device shows information from multiple frames in a single screen draw. [2] The artifact occurs when the video feed to the device is not synchronized with the display's refresh rate.
In cryptozoology and ufology, "rods" (also known as "skyfish", "air rods", or "solar entities") are elongated visual artifacts appearing in photographic images and video recordings. Most optical analyses to date have concluded that the images are insects moving across the frame as the photo is being captured, although cryptozoologists and ...
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.

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 ...
Lens flare on Borobudur stairs to enhance the sense of ascending. A lens flare is often deliberately used to invoke a sense of drama. A lens flare is also useful when added to an artificial or modified image composition because it adds a sense of realism, implying that the image is an un-edited original photograph of a "real life" scene.
