A
Hunting
Repeated brightening and darkening of an image resulting from repeated
response to automatic iris control.
IRE scale
The scale to determine video signal amplitudes devised by the Institute
of Radio Engineers (IRE), an American organization now called the
Institute of Electrical and Electronic Engineers (IEEE).
IT
Interline Transfer. A type of CCD imager.
LTC
Longitudinal Time Code. A time code recorded along the tape in the
forward direction of a tape run. A VTR cannot reproduce LTC when tape
run stops to output a still picture. The output level of LTC is very low
when tape runs slowly, so an LTC read error is likely to occur while the
VTR is playing back in slow motion. See also Time code and VITC.
ND filter
Neutral Density filter. ND filters reduce the amount of incident light
equally across the entire visible wavelength range without affecting
color.
R/G mixing detail circuit
A circuit used to mix R and G signals to obtain a Y signal so that a sharp
picture is reproduced.
Reference video signal
A video signal that contains a sync signal or sync and burst signals, used
as a reference for synchronization of video equipment.
