Crispedges

Crispedges is a term used to describe a phenomenon where the edges of a digital image or display appear unnaturally sharp or jagged. This can manifest as a stair-step effect on diagonal lines, or a harsh, defined outline around objects that should otherwise be softer. While some level of aliasing, or jaggies, is inherent in digital rendering due to the discrete nature of pixels, "crispedges" often implies an exaggerated or undesirable appearance of this effect.

The causes of crispedges can vary. It can be a result of low-resolution source material being scaled up, leading to the visible pixel grid. In some cases, it might stem from image processing techniques that intentionally increase sharpness, or conversely, from a lack of proper anti-aliasing filters being applied during rendering or scaling. Certain display technologies or settings can also contribute to the perception of crispedges, especially when viewed at close distances or with suboptimal scaling algorithms. While not a technical term with a precise definition, it is commonly understood by designers, photographers, and computer users to describe this visual artifact.
