pildiskaneerimine

Pildiskaneerimine, also known as image scanning, is the process of converting a physical image, document, or object into a digital format. This is typically achieved using a scanner, which captures the visual information and translates it into a digital file. The resulting digital image can then be stored, viewed, edited, and shared on computers and other electronic devices.

There are various types of scanners available, each suited for different purposes. Flatbed scanners are common for scanning documents, photographs, and even small objects. Sheet-fed scanners are designed for high-volume document scanning, automatically feeding pages through the device. Handheld scanners offer portability and are often used for scanning barcodes or small sections of larger documents. Specialized scanners exist for tasks such as film scanning or 3D object scanning.

The scanning process involves placing the item on the scanner's glass or feed mechanism. The scanner then illuminates the item, and a sensor moves across its surface, capturing light reflections. This data is processed and converted into a digital image file. Common file formats for scanned images include JPEG, PNG, and TIFF, each offering different levels of compression and quality.

Pildiskaneerimine is widely used in many fields. Businesses use it for archiving documents, digitizing records, and creating digital copies of important papers. Individuals use it to preserve old photographs, digitize personal documents, and create digital versions of artwork. Libraries and archives employ scanning to make their collections accessible online and to preserve fragile materials. The accuracy and resolution of the scan can be adjusted depending on the intended use of the digital image.
