YUV processing
Following the RGB processing, the R, G and B signals are
converted to YUV 4 : 2 : 2 by a fixed matrix (see Fig.5).
Then, the luminance and chrominance signals are
processed separately.
8.5.1
Y
PROCESSING
The luminance processing consists of edge enhancement
and noise reduction (see Fig.5).
The edge enhancement feature is very flexible. First, it is
possible to adjust the bandwidth and the level of the edge
detection. Secondly, the amount of edge enhancement
can be independently adjusted for the horizontal or vertical
edge or for the high or low frequency edges. The edge
detection is also used for the false colour correction.
The noise reduction on the luminance signal is done by a
coring filter. The amount of coring is adjustable.
