Abstract
The first and second fields of an interlaced reference picture are subsampled in the same phase in the horizontal direction to produce a primary search reference picture. The first and second fields of an interlaced motion vector detecting picture are subsampled in different phases to produce a primary search motion vector detecting picture. From the primary search reference picture is extracted a primary search reference block which is similar to a primary search motion vector detecting block which is a partial area in the primary search motion vector detecting picture. A search is made for a candidate field motion vector associated with the primary search reference block. A secondary search is made with the candidate motion vector taken as the search center, thereby detecting final field and frame motion vectors.
