APPARATUS AND METHOD FOR FAST MOTION ESTIMATION BASED ON REDUCED SEARCH RANGES

摘要

One device and a kind of method, for estimating that the high speed motion resetted by using the field of search is only arranged to carry out estimation within set search region. One estimation part (170) includes the calculating part (210) of a norm. The specification for calculating part and calculating a macro block of norm, the entire position with 16x16 units, within the frame of reference and specification of current macro. One grieved (sum of absolute distance) calculate part (220) be calculated as (0,0) motion vector it is sad and the result after operation is set as grieved reference. Specific macro block is divided into nine rectangular search regions and region of search for the first time is arranged by one field of search set parts (230).
