Abstract
A method of determining field dominance in a sequence of video frames, the method comprising: generating from a first video frame a top field and a bottom field; interpolating the top and bottom fields to produce an interpolated top field frame and an interpolated bottom field frame respectively; correlating each of the interpolated top field frame and interpolated bottom field frame with a second video frame occurring immediately previous to the first video frame in the sequence of video frames and with a third video frame occurring immediately subsequent to the first video frame in the sequence of video frames; and determining from the outcome of the correlation the field dominance of the sequence of video frames.
