A VGA camera is considered to be an early evolution of film cameras. Digital cameras are typically identified by a megapixel rating which denotes the highest resolution of the images they can capture, in pixels. The biggest advantage of the VGA configuration is the small file size. This allows for more photos to be taken and faster transfers using less bandwidth. Nowadays, most webcams seem to have a higher resolution, but it may still be enough for a front-facing camera on a phone.
VGA (Visual Graphics Array) resolution is 640 pixels wide by 480 pixels high, or 0.3 megapixels. If you want to share photos by email, post them on a web page, or use them in a multimedia presentation, you can do it with a camera with VGA resolution.
VGA is larger than CIF, QCIF, and QVGA, but smaller than 1 megapixel. (VGA is equivalent to 0.3 megapixels). By modern standards, this is pretty dated and low-res.
Digital cameras, including those that use VGA, store their images directly within the camera’s memory or on a memory card. The images can then be transferred to a computer for printing or sent to a TV screen for public viewing via wireless Internet, Bluetooth, or a USB cable.
VGA cameras are cheap to make, which is why they are most often used in low-end mobile phones and webcams. Toy cameras aimed at children also predominantly use the VGA standard. With the advent of high megapixel cameras, conventional digital cameras no longer use the VGA standard. Other devices that contain small hidden cameras, such as binoculars, goggles, or novelty “spy cameras” can also make use of the VGA standard.
