As the human visual system is more sensitive to details in luminance than to details in chrominance
, the chrominance
components can be compressed at high rate.
High compression of chrominance
data by use of segmentation of luminance.
Furthermore, film and digital cameras, as well as computers, produce images with varying levels of luminance and chrominance
, not all of which meet broadcast standards.
Video quality challenges, such as luminance and chrominance
separation and resolution, have existed since the 1950s.
These HDTV standards follow a 4:2:2 convention where luminance and chrominance
signals are separated onto two different 8- or 10-bit data paths.
These include peaking, sub-pixel luminance sharpness enhancement (LSE), chrominance
sharpness enhancement (CSE) and dynamic histogram-based contrast adjustment.
The Adaptive Color and Contrast(TM) Function enhances the consumer viewing experience by maximizing the luminance and chrominance
dynamic range of the LCD panel.
Two separate color decoders with 2D/3D comb filters for NTSC and PAL eliminate irritating chrominance
and luminance artifacts.
The FMS6414 is perfectly suited for S-Video and other similar applications where the chrominance
(chroma) and luminance (luma) are separated.
Fairchild's FMS6406 offers separate chrominance
and luminance outputs to directly drive the S-video output.
Additional quality enhancing features include integrated anti-alias filters that improve the video decoding process, and an adaptive 4H luminance and chrominance
comb filter that improves the color separation process to provide crisper video images.
Pro- fessional scopes provide precise monitoring of chrominance
and luminance val- ues via waveforms, histograms and new 3D scopes.
