In terms of camera features, "VGA" stands for "video graphic array," and it is a standard resolution size for camera sensors, displays, photos and videos. VGA measures at 640 pixels wide by 480 pixels tall. This resolution is low for standard photos but is equivalent to a standard definition television for videos.
VGA was first introduced by IBM as the display hardware for its line of computers in 1987. The VGA interface is mostly used for high definition video because, while its bandwidth supports high resolution playback, picture quality can suffer degradation depending on the quality and length of the supporting cables.
