| 主权项 | 1. A motion vector extraction method comprising: deciding on a search start position in an original video and performing a spiral motion search; and determining whether or not to perform the search in a sub-sampling video, during P picture search, wherein the determining of whether or not to perform the search comprises: calculating a standard deviation between X and Y components of a motion vector calculated whenever the P picture search is completed; comparing the calculated standard deviation with a predetermined threshold value; and performing motion search in the sub-sampling video, when the standard deviation is smaller than the threshold value. | ||
