Abstract
In a method of processing input fields (I) of a picture signal to obtain interpolated fields (O) located temporally between the input fields (I), motion vectors (MV) are provided (30) between input fields (I), whereafter a quality (Err) of the motion vectors (MV) is assessed (40). In dependence upon the assessed quality (Err), the motion vectors (MV) are adapted (50, 60) such that both decreased and increased motion vector lengths occur in respective interpolated fields (O). The interpolated fields (O) are obtained (20) from the input fields (I) in dependence upon the thus adapted motion vectors (k*MV).
