Glossary 71
• LVDS
Low-voltage differential signalling . LVDS offers a general-purpose, high bandwidth
interface standard for serial and parallel data interfaces that require increased
bandwidth at high speed, with low noise and power consumption.
• Progressive scanning
Describes a transfer of data in which the lines of the source are written sequentially
into the destination buffer.
See also interlaced scanning .
• Real-time processing
The processing of an image as quickly as the next image is grabbed.
Also known as live processing .
• Rotary encoder
A device used to convert the angular position of a shaft or axle to an analog or
digital code.
• Saturate
To replace overflows (or underflows) in an operation with the highest (or lowest)
possible value that can be held in the destination buffer of the operation.
• Timer output
The signal generated by one of the programmable timers of a frame grabber, which
can be used to control external hardware. For example, it can be fed to the video
source to control its exposure time or used to fire a strobe light.
• UART
Universal Asynchronous Receiver/Transmitter. A component that handles
asynchronous communication through a serial interface (for example, RS-232 or
LVDS).
