AN5385K
Contour correction IC
s
Overview
The AN5385K is an IC which conducts contour
correction for luminance signal and color differ-
ence signal. It corresponds to all broadcasting sys-
tems of PAL, NTSC and SECAM. Fewer external
parts enables the TV sets to be less cost and high
picture quality.
s
Features
Black side contour emphasis and white side shoot
elimination circuit are built in (for anti-blooming)
Transient correction of color difference signal
(color missing improvement)
Red gamma correction circuit built in
Wider band of signal processing (Y: 7 MHz/
-
3
dB, Color difference: 3 MHz/
-
3 dB)
Delay time is identical for both Y and color
difference.
Delay amount switch is built in
Delay line and coupling condenser built in
