Y/C Separation
Y/C separation can be done using adaptive 5-line (5-H delay) comb filters or a chroma trap filter. The
comb filter can be selectively bypassed in the luma or chroma path. If the comb filter is bypassed in the
luma path, then chroma trap filters are used which are shown in Figure 3-6 and Figure 3-7. The TI
patented adaptive comb filter algorithm reduces artifacts such as hanging dots at color boundaries. It
detects and properly handles false colors in high-frequency luminance images such as a multiburst pattern
or circle pattern.
