Abstract
A method of processing interlaced video data including a first interlaced field and a second interlaced field is provided. The method includes performing a deinterlacing operation upon the interlaced video data to generate a first deinterlaced frame corresponding to the first interlaced field and to generate a second deinterlaced frame corresponding to the second interlaced field; performing motion estimation according to video information derived from the interlaced video data to generate a motion estimation result; and performing a blending operation upon the first deinterlaced frame and the second deinterlaced frame to generate an output frame. The blending operation is based on the motion estimation result, and the output frame replaces the second deinterlaced frame. Specifically, the first interlaced field is immediately followed by the second interlaced field.
