Abstract
A first matching operational circuit detects correlation between output signal of the reference block memory and the search block memory with integer-pel accuracy. A second matching operational circuit detects correlation between output signal of a reference block buffer memory and a search block buffer memory with less than or equal to half-pel accuracy. The first matching operational and the second matching operational circuit are operated in parallel.
