• Dynamic range.
The range of values present in a buffer. An unsigned 8-bit buffer, for example, has
an allowable range of 0 to 255; its dynamic range can be any range within these
values.
• Exposure time.

A device that provides information about the linear position and direction of a
moving sensor along a scale, either as an analog or digital code.
• LVDS.
Low-voltage differential signaling . 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.
• PCIe.
Peripheral Component Interconnect Express . The standard used for the computer
bus that acts as an interface between hardware devices, such as Matrox Rapixo
CXP, and your computer.
