    摘要: A video encoder and a motion estimation method are provided. The video encoder comprises a storage unit and an integer motion estimation unit. The storage unit receives a current image block and a plurality of search windows from at least two reference frames. The integer motion estimation unit coupled to the storage unit computes a plurality of integer motion vectors according to the current image block and the plurality of search windows. A number of the reference frames and a size of the search windows are adaptively changed such that space requirement thereof is less than or equal to available space in the storage unit.

    摘要: Sub-sampling pattern design for motion estimation in video compression. A motion estimation method divides a first frame into a plurality of macroblocks, performs block matching for a current macroblock pair on a candidate macroblock pair of a second frame. The current macroblock pair and the candidate macroblock pair are sampled according to a sub-sampling pattern, and an error measure between the current and candidate macroblock pairs is calculated. The sub-sampling pattern is constructed by a plurality of repeating units, and each repeating unit is composed of a first and a second pattern unit.

    摘要: A method for performing a specific image processing upon data loaded in a memory unit. The method includes loading non-overlapping pixel data of a second image processing range in a second reference frame into the memory unit, wherein the non-overlapping pixel data are pixel data not within an overlapped area of the first and second image processing ranges; and before the non-overlapping pixel data are completely loaded into the memory unit, start performing the specific image processing upon overlapping pixel data of first and second image processing ranges in a first reference frame.
