Function
It set the Contrast. (Reference value: [01000000])
Variability is ×0.5〜×2.4.
(When use big value and inputs big amplitude signal,
It takes place over range of internal circuit.)
It set the Brightness.
Variability is -128LSB 〜 +128LSB.
It set Gain of Cr. (Refrence value:[0000])
Variability is ×0.5〜×1.4.
(When use big value and inputs big amplitude signal,
It takes place over range of internal circuit.)
It set Gain of Cb. (Refrence value:[0000])
Variability is ×0.5〜×1.4.
(When use big value and inputs big amplitude signal,
It takes place over range of internal circuit.)
HUE adjustment at the NTSC input mode.
Variable is -45°-+43.6 °.
Setup BPF for feed-back-clamp. [1]:ON [0]:OFF
Normaly It must be set [1].
Fine tune HUE-Bias at the NTSC input mode.
Variable is 0°〜+45°.
Use [1] at the digital-clamp-mode.
[1]: Clamp OFF [0]: Clamp ON. It usually uses on [1].
Offset adjustment for Y signal at Analog-input.
Use with 0[mV] when you use with digita-clamp.
Setup C-trap for Y at Digital-COMB-block.
[1]: ON [0]: OFF. This setup can reduce Cross-color and beat.
Take-off-Filter is put in front of Decoder. 000:OFF、001:
BPF、010〜111:TOF(TOF1〜TOF6)
When BPF is set up, it can't get the effect of TOF.
Digital-clamp is put by input-Y-signal
Adjustment of the phase of Digital-clamp-pulse for Y.
Reference value:[011].The variable is about 0.3[μs] step.
Adjustment of the width of Digital-clamp-pulse for Y.
Reference value: [011].Variable is about 0.3[μs] step.
It can select ON/OFF of Digital-clamp-Y. And adjustment of
time constant of Digital-clamp-Y.
Adjust the offset of the Cr at input by YCbCr signal.
Use with 0[mv] at the time of Digital-clamp.
Variable is -31[mV] 〜 +27[mV].
Adjust the offset of the Cb at input by YCbCr signal.
Use [0000] at the Digital-clamp mode.
Variable is -31[mV] 〜 +27[mV].
Adjust the clamp-phase of Cb/Cr at YCbCr signals.
It usually uses on BUS:[0000].
