<p>The present invention discloses a method of inter-frame Y/C separation. The method first samples a composite video signal for temporarily storing a plurality of sampled data F<Sub>m</Sub>P<Sub>x,y</Sub>, wherein the F<Sub>m</Sub>P<Sub>x,y</Sub> represents data of the y pixel at the x line of the m frame, and the m, x and y are integers larger than, or equal to, 0. Then the method measures a plurality of luma data Y<Sub>x,y</Sub> by the F<Sub>m+1</Sub>P<Sub>x,y</Sub>, the F<Sub>m</Sub>P<Sub>x,y</Sub>, the F<Sub>m-1</Sub>P<Sub>x,y</Sub> and the F<Sub>m-2</Sub>P<Sub>x,y</Sub>, wherein Y<Sub>x,y</Sub> represents luma data of the y pixel of the x line. Finally, the method measures a plurality of chroma data C<Sub>x,y</Sub> by the F<Sub>m+1</Sub>P<Sub>x,y</Sub>, the F<Sub>m</Sub>P<Sub>x,y</Sub>, the F<Sub>m-1</Sub>P<Sub>x,y</Sub> and the F<Sub>m-2</Sub>P<Sub>x,y</Sub>, wherein C<Sub>x,y</Sub> represents luma data of the y pixel of the x line.</p> |
