Quarter Video Graphics Array
From Biocrawler, the free encyclopedia.
The Quarter Video Graphics Array (also known as Quarter VGA or QVGA) is a popular term for a computer display with 320x240 resolution. QVGA displays are most often seen in mobile phones and PDAs. Most often the displays are portrait mode (other mode is landscape) and are referred to as 240x320 as the displays are taller than they are wide.
The name is derived from the fact that it offers 1/4 of the 640x480 maximum resolution of the original IBM VGA display technology, which became a de facto industry standard in the late 1980s. QVGA implementations are not compatible with, nor directly derived from, standard VGA chipsets or interfaces; the term refers only to the display's resolution.
The QVGA term is also seen in digital video recording equipment as a space-efficient mode, typically in multi-function devices that are also still digital cameras (such as the Fujifilm FinePix S602) or mobile phones (such as the Pantech PH-L4000V). Each frame is an image of 320x240 pixels. QVGA video is typically 15 or 30 frames per second. QVGA mode refers just to the resolution and is not a video file format.
