1. A deinterlacing apparatus, comprising:
a motion compensation unit implementing motion-compensated temporal interpolation for each of estimated motion vectors with
reference to a previous field and a next field, which are respectively ahead of and behind a current field to be interpolated,
producing interpolation values of a pixel to be interpolated, and outputting a selected value from the interpolation values
as a first interpolation value;
a spatial interpolation unit producing a second interpolation value of the pixel to be interpolated using values of pixels
around the pixel to be interpolated; and
an output unit mixing the first and second interpolation values with a weighted value and outputting a value indicative thereof.
