Abstract
A method of converting a frame rate of a video signal includes the steps of: receiving a pulldown film sequence existing in or converted from a sequence of successive-in-time frames of the video signal, in which the pulldown film sequence comprises a plurality of diverse original frames each having a corresponding number of duplicate frames; modifying the original frames; performing estimation of at least one motion vector associated with the modified original frames; and interpolating new frames between the modified original frames in accordance with the motion vector.

A method of converting a frame rate of a video signal, comprising the steps of:
- receiving a pulldown film sequence existing in or converted from a sequence of successive-in-time frames of the video signal, wherein the pulldown film sequence comprises a plurality of diverse original frames each having a corresponding number of duplicate frames;
- modifying the original frames;
- performing estimation of at least one motion vector associated with the modified original frames;
- and
- interpolating new frames between the modified original frames in accordance with the motion vector.
A method of converting a frame rate of a video signal, comprising the steps of:
- receiving a sequence of frames existing in or converted from the video signal;
- performing motion estimation of the sequence of frames;
- determining based on the motion estimation if the sequence of frames being pulldown film sequence comprising a plurality of diverse original frames each having a corresponding number of duplicate frames;
- modifying the original frames when the sequence of frames being pulldown film sequence;
- performing estimation of at least one motion vector associated with the modified original frames;
- and
- interpolating new frames between the modified original frames in accordance with the motion vector.
