| Abstract(in English) | A fast-motion-estimation (ME) algorithm called a "Multi-step Breaking-0ff-Search (MS-BOS)" method was developed. Sizes of the search areas were optimized to improve block-matching speed while maintaining picture quality. It can improve processing speed of the full-search (FS) method by a factor of 6 to 63, depending on picture types, while maintaining visual quality of the full-search method. At clock frequency of 260 MHz and supply voltage of 1.8 V the power dissipation of a 0.18-μm CMOS accumulation type motion estimator using MS-BOS and gated-clock technique was reduced to 12.3 μW which was only 1.6% that using FS and gated-clock technique. |
