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.
