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 ...
A still video camera (SVC) is a type of electronic camera that takes still images and stores them as single frames of video. 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 ...
Windows Camera is an image and video capture utility included with the most recent versions of Windows and its mobile counterpart. It has been around on Windows-based mobile devices since camera hardware was included on those devices and was introduced on Windows PCs with Windows 8, providing users for the first time a first-party built-in camera that could interact with webcam hardware.

After you capture a normal screenshot, you'll see an icon for scroll capture to do it. To record your screen for video, you can go to quick settings then choose the screen recorder. How to ...
This is usually a two-way port, so that DV video data can be output to a computer (DV-out), or input from either a computer or another camcorder (DV-in). The DV-in capability makes it possible to copy edited DV video from a computer back onto tape, or make a lossless copy between two mutually connected DV camcorders.
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.
The tracking computer is responsible for capturing the images from the optical imaging system, analyzing the image to extract the target position and controlling the mechanical tracking platform to follow the target. There are several challenges. First, the tracking computer has to be able to capture the image at a relatively high frame rate.
