A technique used to make scanned images sharper.

OBS

The process of scanning an image can make the image appear soft; high-end drum scanners perform unsharp masking automatically to create a sharper, crisper image. Flatbed scanners usually do not perform unsharp masking. Image editing applications such as Adobe Photoshop can be used to unsharp mask an image. (The name "unsharp masking" comes from the pre-computer photographic process used to sharpen a blurry negative.)
