Pixlighet

Pixlighet refers to the perceived lack of detail or clarity in a digital image, often appearing as blockiness or a general coarseness. This phenomenon typically arises when an image is displayed at a resolution lower than its original capture or creation, or when it has been resized upwards significantly without sufficient data. When a pixel, the smallest controllable element of a picture on a screen, is enlarged beyond its intended size, its individual square or rectangular shape can become apparent, leading to a visually unappealing pixlig effect.

The causes of pixlighet are varied. Digital cameras and image sensors have finite resolutions, and images captured at lower settings will inherently contain less information. When these images are then viewed on high-resolution displays or printed at larger sizes, the limited pixel data is stretched, revealing the underlying pixel grid. Similarly, image editing software can introduce pixlighet if an image is scaled up using basic interpolation methods that simply replicate existing pixels rather than creating new, interpolated ones. Compression algorithms, especially lossy ones like JPEG when used at high compression ratios, can also break down image detail and contribute to pixlighet, particularly in areas of subtle color gradients. Over-editing, such as aggressive sharpening, can sometimes create artifacts that mimic or exacerbate pixlighet.
