Glossary Terms
In camera terms, VGA refers to a digital image of resolution of 640x480 pixels.
The term comes from the Video Graphics Array display hardware first introduced with the IBM PS/2 computer in 1987, which had a maximum resolution of 640x480 and 8-bit colour depth, giving 256 possible colours. This size adopted as a standard by many other graphics boards. VGA also denotes the 15-pin D-connector which became standard for analog monitor connections.
