Preliminary specification
Digital Signal Processor (DSP) for
cameras
SAA8110G
RGB-to-YUV block
After RGB processing, the channels are separated in a
luminance and two colour difference path:
Y = 0.299 R + 0.597 G + 0.114 B, U = 0.49 (B
Y) and
V = 0.88 (R
Y) . It also contains two down-sampling
filters for U and V signals.
Y-processing
The luminance component includes several features:
Contour correction allowing an increase of the
luminance transitions for a sharper picture
Black stretch function for contrast enhancement in dark
scenes
False colour detector used by the UV-processing block
to enable the colour killer
Filters and noise reduction by coring (only in the high
frequency part of the signal).
