In optics and photography, unschärfer describes areas of an image that are not in focus. Blurriness can result from defocus, camera or subject movement, lens aberrations, or atmospheric effects. The degree of unschärfe is contrasted with Schärfe (sharpness) and with Schärfentiefe (depth of field), which defines the range of distances that appear acceptably sharp.

In digital image processing, blur andsharpness are manipulated with algorithms. Blurring can be applied to reduce noise or simulate depth, while sharpening techniques aim to reduce perceived unschärfe by increasing local contrast at edges. A well-known sharpening method is the unsharp mask, or in German, unscharfmaskierung or unscharf maskieren, which enhances perceived detail by amplifying edge contrasts.

Linguistically, unscharf and its comparative unscharfer function as standard German adjectives. Example: Der Rand ist unscharfer als der Rest des Bildes.
