*Sub address 16h(D7)
It can shift to motion seen for 2F motion detection of chroma signal.
If BCMUP is on, it can decrease a dot noise for continuous color change.
It must be attentive to increase a cross color noise when 2F motion detection for chroma is nearly motion.
*Sub address 19h 2F correction
It can control a phenomenon which the picture is in spite of still, it is treated as motion seen and appeared cross color
noise.
19h(D7) 0:2F correction off 1:2F correction on
19h(D6) select a judgment standard signal
0:Working as base on motion detection result for 2F Y
1:Working as base on motion detection result for 2F C
19h(D5-D3) Setting a judgment level for working this function
000:off (same D7=0)
001:It is little effect
111:It is much effect
19h(D2) Setting motion detection for 2F correction
00: Moving picture direction
11: Still picture direction
Sub address 19h(D0) CROS
In case of moving picture for high frequency of Y signal, it can reduce a cross color noise.
