    摘要： A method of selecting a motion vector for use in a motion estimation system in which the motion vector defines movement of a block of pixels between a search window and a reference frame. The method includes the steps of scanning a search window in a fixed order for a suitable match with an area of the reference frame such that each search position within a current row or column of the window is one pixel away from a previous search position, defining a preferred point in the search window, calculating a primary norm function with reference to the preferred point for a given position in each row or column, calculating a norm function for each search position based on a linear increment of the primary norm function for the respective row or column, calculating an Absolute Error (AE) for each search position, based on a difference between a given property of the search position and a position in the reference window, and selecting a motion vector, the displacement of the motion vector defined in terms of the search position having the smallest AE and the smallest norm function. An apparatus for performing the method is also disclosed.

    摘要： A circuit for squaring a binary number X of n bits, x.sub.0 to x.sub.n-1, includes pre-processing circuits to form a group of all the products x.sub.i y.sub.j of the bits of number X, where i and j vary between 0 and n-1 such that i.ltoreq.j. The outputs of the pre-processing circuits provide words such that each word is formed by a succession, as complete as possible, of products selected among the products remaining from the group of products after forming the preceding word, each product x.sub.i y.sub.j of this succession being affected with a weight i+j+1 of the word if i is different from j, or with a weight 2i if i=j. Adders are connected to sum the words as the square of the number X.

    摘要： A method and apparatus of encoding digital video, for example according to the ISO/IEC MPEG standards (ISO/IEC 11172-2 MPEG-1 and ISO/IEC 13818-2 MPEG-2), which employs a local motion estimator for determining respective local motion vectors for groups of adjacent macroblocks in a picture. A local motion vector is determined for each row of macroblocks in a picture from the motion vectors of the macroblocks in that row. Then, for macroblocks in the corresponding row of a subsequently coded picture, the local motion vector can be used to select the search window used for determining the motion vectors. The local motion estimator improves search range and accuracy of macroblock motion vector detection without increasing the search window accessing bandwidth and caching requirement, and computation lode of searching.

    摘要： Method of compressing a digital image signal in which a first quantization step set, which is unique for a given segment, is determined so that the number of bits needed to encode the quantized data corresponding to this segment is greater than a target value. This first quantization step set then being modified, as a priority, for the blocks of the segment for which the gain, in the course of this modification, on the reduction of the number of bits needed to encode the quantized data corresponding to the segment to which it belongs, is the highest. This modification is carried out, on as many blocks as is necessary for the number of bits of this segment to be less than or equal to the target value. Device to implement this method.
