USB video class support for Linux is provided by the Linux UVC driver, although as of July 2017 support for still-image capture is not yet implemented. [4] The UVC driver has been included in the Linux kernel source code since kernel version 2.6.26.
The frametimes benchmark feature (logging of individual frame render times) gained attention in 2013 on computer review sites in debate about micro stuttering in games. [2] On Windows Vista and Windows 7, the desktop can be captured if Windows Aero is enabled. Windows 8 game capture works, but not desktop capture as of version 3.5.99. [3]

They peaked in popularity in the late 1980s [citation needed] and can be seen as the predecessor to the digital camera. However, unlike the latter, the image storage in such cameras is based on analog technology, rather ...
Rolling shutter describes the process of image capture in which a still picture (in a still camera) or each frame of a video (in a video camera) is captured not by taking a snapshot of the entire scene at a single instant in time but rather by scanning across the scene rapidly, vertically, horizontally or rotationally. Thus, not all parts of ...
Few capture in standard TV-video formats (480p60, 720p60, 1080i30), recording in either non-TV resolutions (320x240, 640x480) or slower frame rates (15 or 30 fps). A multipurpose device used as a camcorder offers inferior handling, audio and video performance, which limits its utility for extended or adverse shooting situations.
Normally, two fields comprise one video frame, in what is known as 2:1 interlacing. 3:1, 4:1 and 5:1 interlacing also exist. [ 1 ] [ 2 ] When the fields are displayed on a video monitor they are " interlaced " so that the content of one field will be used on all of the odd-numbered lines on the screen, and the other field will be displayed on ...
