摘要
A method of processing an input 60 field/second video signal generated by 3232 pulldown to produce an output video signal, comprises producing from the input signal a series of progressive scan format frames, each frame corresponding to a respective one of the input fields, and comparing blocks of pixels in each progressive scan frame with blocks of pixels in the following frame to derive motion vectors representing the motion of the content of respective blocks between frames. The motion vectors are utilized to monitor the field sequence of the input signal, and fields or frames of the output video signal are produced using input fields or progressive scan frames selected in dependence upon the field sequence of the input signal, at least some of the output fields or frames being produced by motion compensated temporal interpolation utilizing the motion vectors.
