Horizontal sync
■
The part of a video signal that indicates the end of a line and

then the even-numbered lines (or vice-versa).
See also progressive scanning.
Latency
■
The time from when an operation is started to when the final
result is produced.

LUT mapping
■
Look-up 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 Signaling. It is a way to
communicate data using a very low voltage swing (about
350mV) over two differential printed circuit board (PCB)
traces or a balanced cable.
