•
LUT mapping
Lookup table mapping. A point-to-point operation that uses a table to define a
replacement value for each possible pixel value in an image.
•
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.
•
Reference levels
The zero and full-scale levels of an analog-to-digital converter. Voltages below a
black reference level are converted to a zero 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.
•
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.
•
Stream
The communication path through which nodes can transmit data.
