käsiskanner

Käsiskanner, also known as a handheld scanner, is a portable device used to capture images or text from documents. Unlike flatbed scanners, which require the document to be placed on a glass surface, a handheld scanner is moved across the item being scanned. This mobility makes them useful for digitizing items that cannot be easily placed on a flatbed, such as books, newspapers, or larger documents.

These devices typically consist of a scanning element that is slid along the surface of the material. The user must maintain a steady hand and consistent speed for optimal results. Early models often produced lower-resolution scans and could be prone to distortion if not used correctly. However, modern handheld scanners have improved significantly, offering better image quality and features.

Käsiskannerid can be used for various purposes. Students might use them to quickly scan lecture notes or textbook pages. Professionals may employ them for archiving documents or capturing information on the go. They are also utilized in retail for inventory management and in libraries for cataloging.

The operation of a käsiskanner usually involves connecting it to a computer or a mobile device via USB or Bluetooth. The scanned data is then transferred and can be processed using accompanying software. This software often includes optical character recognition (OCR) capabilities, allowing scanned text to be converted into editable digital text. Some handheld scanners also have built-in memory to store scans before transferring them.
