[background technology]
In simulated television, the composite video signal of picture (composite video signal) comprises a luminance signal (Y) and a carrier chrominance signal (C).Comb filter is generally used for this composite video signal to isolate luminance signal and carrier chrominance signal, and the process of isolating luminance signal and carrier chrominance signal is called Y/C and separates (Y/C separation).
Comprise three kinds for separating of the comb filter of composite video signal, these three kinds of comb filters are divided into one dimension (1D) comb filter, two dimension (2D) comb filter and three-dimensional (3D) comb filter.One dimension comb filter and two-dimensional comb filter are non-three-dimensional (non-3D) comb filter.In general, when picture is while being dynamic, utilize non-three-dimensional comb filter to isolate luminance signal and carrier chrominance signal, when picture is while being static, utilize three-dimensional comb filter to isolate luminance signal and carrier chrominance signal.
In the time that the picture of quiescent conditions is subject to noise effect, picture there will be the situation of slow movement.Therefore, use non-three-dimensional comb filter can cause situation unstable and pore shape (sparkle-like), that is to say, picture is not really to move, but uses mistakenly non-three-dimensional comb filter.Therefore need to propose a solution to compensate the luminance signal of non-three-dimensional comb filter output, to avoid the situation of above-mentioned unstable and pore shape.
