Quarter Video Graphics Array is one of the advanced Display-based technologies or a display mode that comes in a small screen with a horizontal resolution of 320 pixels and 240 pixels vertically. The resolution provided by this screen can be 240*320.
These displays are commonly used in different electronic devices and small computers. You will also find this screen in digital cameras, mobile phones, handheld games, MP3 players, and many other types of portable equipment. This display option also comes with the feature of a touch screen.
Applications of QVGA
1. QVGA has been implemented in Heterogeneous Visual Sensor Networks.
It is a multi-tier WSN architecture specially applicable for surveillance applications. SensEye consists of three tiers, In which the first tier is made up of Quarter Video Graphics Array (QVGA) camera for the purpose of detecting an object, whereas second and third tiers are composed of VGA and pan-tilt-zoom cameras respectively for object recognition and tracking moving objects.
2. Video Conferencing and Film Industry
QVGA images can be easily integrated into video conferencing system through utilizing some video compression standards.
3. Digital Imaging
3D integration technology can be implemented with quarter video graphics array (QVGA) chip for full-digital imaging purposes.
