Skannerilaitteella

Skannerilaitteella refers to the use of a scanner device. A scanner is an input device that optically scans images, printed text, or objects and converts them into a digital signal. This digital signal can then be processed by a computer, displayed on a monitor, stored in a file, or transmitted. Scanners are commonly used for digitizing documents, photographs, and other physical media.

There are various types of scanners, including flatbed scanners, sheet-fed scanners, and handheld scanners. Flatbed scanners are the most common type for home and office use, allowing users to place documents or objects directly onto a glass surface. Sheet-fed scanners are designed for high-volume document scanning and automatically feed pages through the device. Handheld scanners are portable and can be moved across the surface being scanned.

The scanning process involves light passing over the physical item, and a sensor capturing the reflected light. This captured information is then converted into binary data, representing the image or text. Software is typically used to control the scanner's settings, such as resolution, color depth, and file format, and to process the scanned data. Common file formats for scanned images include JPEG, PNG, and TIFF. For documents with text, optical character recognition (OCR) software can be used to convert the image of text into editable digital text.
