Abstract
In a method of estimating motion vectors, motion parameters (p1-p4) are determined (PC) for a given field (n−1) of a video signal; and motion vectors ( D(X, n) ) for a field (n) of said video signal are determined in dependence upon at least one predetermined motion vector ( D(x−X, y−Y, n), D(x+X, y−Y, n), D(x, y+2Y, n−1) ) and at least one additional motion vector (PV(X) derived (PG) from said motion parameters (p1-p4).
Claims11
A method of estimating motion vectors, comprising the steps of:
- determining motion parameters for a first field of a video signal;
- providing at least one predetermined motion vector;
- deriving at least one parameter based motion vector from said motion parameters;
- and
- determining a motion vector for a second field of said video signal based upon said at least one predetermined motion vector and said parameter based motion vector.
2 more elements
A motion vector estimation device, comprising:
- means for determining motion parameters for a first field of a video signal;
- and
- means for determining motion vectors for a second field of said video signal based upon a predetermined motion vector derived from previous motion vectors and a parameter based motion vector derived from said motion parameters.
