The present invention uses a 2D comb filterto output a 2D chrominance signal Cby comparing the current scan-line signals with the signals before and after the current scan-line signals. A 3D chrominance signal Cis then acquired by directly subtracting two adjacent 2D image signals and then dividing by 2 to get an approximate chrominance signal Cof the two 2D images. Ratio mixing is performed on the 2D chrominance signal Cand the 3D chrominance signal Cto output a near-actual chrominance signal. A chrominance variation value can be acquired by comparing the chrominance signals of the two adjacent images. Finally, an actual luminance signal of the current scan-line is separated by deducting the near-actual chrominance signal from the signals of the current scan-line to restore the luminance signal.
