skänneri

A skänneri, or scanner in English, is an electronic device that optically scans images, printed text, or objects and converts them into a digital format. This digital representation can then be stored, viewed, edited, and transmitted on a computer. Scanners typically work by moving a light source across the surface of the item being scanned, capturing the reflected light with a sensor. The sensor translates the light intensity into digital data.

There are several types of scanners, including flatbed scanners, document scanners, and handheld scanners. Flatbed scanners are the most common type for home and office use, featuring a glass surface where documents or objects are placed. Document scanners are specialized for quickly scanning multiple pages, often with an automatic document feeder. Handheld scanners are portable and can be moved over the item to be scanned, useful for books or irregularly shaped objects.

Scanners are used for a wide range of applications. They allow for the digitization of paper documents, photographs, and artwork, preserving them and making them easily accessible. Businesses use scanners for archiving records, creating digital backups, and streamlining workflows. In graphic design and publishing, scanners are used to import images and artwork into digital projects. The technology has evolved to offer higher resolutions, faster scanning speeds, and improved color accuracy, making them an indispensable tool in many fields.
