MSPS
Mega samples per second.
PCI
Peripheral Component Interconnect. An expansion bus
standard for the '90s.
PLL
Phase-locked loop. A PLL creates a pixel clock which is a
multiple of a referenced signal's frequency; usually the
referenced signal is the horizontal sync. A PLL adjusts the
pixel clock frequency according to changes or variations of its
reference signal. Adjusting the pixel clock frequency ensures
that the same number of pixels appears on every line.
Progressive scanning
Describes a transfer of data in which the lines of the source
input device are written sequentially into the destination
buffer.
Also known as non-interlaced. 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.
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.
