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, chroma trap filters are used which are shown in Figure 2-6 and Figure 2-7. 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. Adaptive comb filtering is the recommended mode of operation.
