Näytönkeruu

Näytönkeruu, a Finnish term meaning "screen capture" or "screenshot," refers to the process of taking a static image of the display shown on a computer monitor or other electronic device. This captured image can then be saved as a file or shared. The functionality is commonly built into operating systems and many applications.

On personal computers, operating systems like Windows and macOS offer dedicated keyboard shortcuts to initiate screen capture. Users can often choose to capture the entire screen, a specific active window, or a selected rectangular region. Mobile operating systems, such as Android and iOS, also provide similar capabilities, typically activated by pressing a combination of physical buttons.

The generated image file can be in various formats, including PNG, JPEG, or BMP, depending on the software or operating system used. Screen captures are frequently employed for technical support, documenting software behavior, creating tutorials, or simply for sharing visual information. Specialized software also exists that offers advanced features beyond basic screen capture, such as capturing scrolling windows or recording screen activity as a video.
