3.3
Adaptive Comb Filtering
The four-line comb filter can be selectively bypassed in the luminance or chrominance path. If the comb
filter is bypassed in the luminance path, then chrominance trap filters are used which are shown in
Figure 3-2 and Figure 3-3. TI's patented adaptive four-line comb filter algorithm reduces artifacts such as
hanging dots at color boundaries and detects and properly handles false colors in high-frequency
luminance images such as a multiburst pattern or circle pattern.
