Field comb for luminance separation of NTSC signals
摘要:
A field comb filter for separating luminance signal from NTSC composite video additively combines signals separated by 263 horizontal lines. Vertical detail is restored and motion compensation provided by subtractively combining signal separated by 262 horizontal lines and adding the difference to the separated luminance signal.
