resolution

The smallest signal increment that can be detected by a measurement 
system. Resolution can be expressed in bits, in proportions, or in 
percent of full scale. For example, a system has 12-bit resolution, 
one part in 4,096 resolution, and 0.0244 percent of full scale.

RGB

Color encoding scheme using red, green, and blue (RGB) color information 
where each pixel in the color image is encoded using 32 bits: eight bits for 
red, eight bits for green, eight bits for blue, and eight bits for the alpha value 
(unused).

ROI

Region of interest. A hardware-programmable rectangular portion of the 
acquisition window.

RS-422

A robust, serial digital data interchange standard utilizing individual 
differential signal pairs for data transmission in each direction. Depending 
on data transmission rates, RS-422 can be used at distances to 4,000 ft 
(1,275 m).

RTSI bus

Real-Time System Integration Bus. The National Instruments timing bus 
that connects Vision and DAQ devices directly, by means of connectors on 
the devices, for precise synchronization of functions.

S

scatter-gather DMA

A type of DMA that allows the DMA controller to reconfigure on-the-fly.

T

tap

A stream of pixels from a camera. Some cameras send multiple streams, 
or taps, of data over a cable simultaneously to increase transfer rate.

transfer rate

The rate, measured in bytes/s, at which data is moved from source to 
destination after software initialization and set up operations. The 
maximum rate at which the hardware can operate.

trigger

Any event that causes or starts some form of data capture.
