•Real-time processing

The processing of an image as quickly as the next image is grabbed. Also known as live processing.

•Reference levels

The zero and full-scale levels of an analog-to-digital converter. Voltages below a black reference level are converted to the minimum pixel value; voltages above a white reference level are converted to the maximum pixel value. Together with the analog gain factor, the reference levels affect the brightness and contrast of the resulting image.

•RGB

A color space that represents color using the primary colors (red, green and blue) as components.

•Start-of-active-video (SAV)

A signal sent along the video input port (VIP) bus, prior to the transmission of the first bit of active video data. This signal indicates the start of active video signal transmission for the current row.

See also End-of active-video.

•Subnet mask

The sequence of numbers that the router uses to determine which parts of the 32-bit IP address is specific to the subnetwork (that is, common to all of the machines on the network) and should be used for transmitting the information “packet” to the subnetwork. This mask saves the router from having to handle the entire 32-bit IP address; instead, it can look at only the bits enabled (set to “1”) by the mask. For example, if the network and subnet addresses are contained in the upper 24 bits, and the specific host address is contained in the lower 8 bits, then you can convey this information to the router to allow quicker transmission to the subnet by passing the following mask value: 255.255.255.0 (11111111.11111111.11111111.00000000).
