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 26 and Figure 27. TI’s 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.
