A frame grabber is an electronic device that captures (i.e., "grabs") individual, digital still frames from an analog video signal or a digital video stream. It is usually employed as a component of a computer vision system, in which video frames are captured in digital form and then displayed, stored, transmitted, analyzed, or combinations of ...
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]
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 ...
The iPhone camera has come a long, long way since the phone was first introduced in 2007. However, there are still some things it can’t do all that well —. like, for instance, take vertical ...

Yes [28] Yes [29] No Vine: Vine was a download-only short-form video hosting service where users could share six-second-long looping video clips. Yes: Yes ...
M-JPEG is an intraframe-only compression scheme (compared with the more computationally intensive technique of interframe prediction).Whereas modern interframe video formats, such as MPEG1, MPEG2 and H.264/MPEG-4 AVC, achieve real-world compression ratios of 1:50 or better, M-JPEG's lack of interframe prediction limits its efficiency to 1:20 or lower, depending on the tolerance to spatial ...
An implementation with separate video tracks within a file or separate video files is not known yet. Voice commands. Voice commands were first featured in 2012 on the camera software of the Samsung Galaxy S3, and the ability to take a photo after a short countdown initiated by hand gesture was first featured in 2015 on the Galaxy S6.

Frame rate, most commonly expressed in frame/s, frames per second or FPS, is typically the frequency (rate) at which consecutive images are captured or displayed.This definition applies to film and video cameras, computer animation, and motion capture systems.
