TC90A92AFG
*Sub address 1Ah Motion detection for 3DNR
1Ah(D7) Select a band width for NR working
0:Wide band (Recommended)
1:Narrow band
1Ah(D6)
When the picture is judged no color, it can control CNR motion detection for decreasing cross color noise.
0:motion detection for CNR is invalid.
1:Using still picture direction parameter
1Ah(D5) Setting non-correlation detection level for motion detection of Y
0:standard
1:two times of standard
1Ah(D4) Setting non-correlation detection level for motion detection of C
0:standard
1:two times of standard
1Ah(D3-D0) Setting Y signal moving amount judgment standard for NR
0000: Moving picture direction (There is little effect of decreasing cross color noise.)
:
1111: Still picture direction (There is many effect of decreasing cross color noise.)
*Sub address 1Fh(D5) COMB+
It has an effect as below for PAL system.
When the horizontal lines of the front and the rear have color and edge element, and the horizontal line of center has no
color, it drops Y signal level for calculated result. Therefore it occurs dots of black in spite of white and gray picture.
When COMB+ is on, it can decrease this noise.
