摘要： A weighting factor mode determination unit determines whether to code an interlaced picture in a field mode or a frame mode, based on a value of a flag “AFF” indicating whether or not to switch between the field mode and the frame mode on a block-by-block basis and notifies switches and a multiplexing unit of the determined mode. The switches select either the field mode or the frame mode according to the notified mode. A field weighting factor coding unit or a frame weighting factor coding unit performs respectively the coding of respective weighting factors when the respective modes are selected.

摘要： A motion vector coding method and apparatus that improves efficiency of coding motion vectors when a current block is coded using a plurality of motion vectors. The apparatus includes a motion vector coding unit that codes a motion vector inputted from a motion vector detecting unit. A motion vector for each current block is coded based on a difference between the motion vector and a predicted vector obtained from motion vectors for previously coded neighboring blocks. The predicted vector is generated by one of the following processes: (A) the motion vectors which refer to the same picture are selected from among the motion vectors for the neighboring blocks so as to generate the predicted vector; (B) the motion vectors for the respective neighboring blocks are ordered in the predetermined order, and the motion vectors of the same order rank are selected from the ordered motion vectors so as to generate the predicted vector; and (C) the predicted vector for the second motion vector of the current block shall be the first motion vector, and if the second motion vector and the first motion vector refer to different pictures, the first motion vector is scaled according to the temporal distance between the pictures so as to generate the predicted vector.

摘要： According to the present invention, a moving picture coding apparatus (70) for performing inter-picture predictive coding for pictures constituting a moving picture is provided with a coding unit (103) for performing predictive error coding for image data; a decoding unit (105) for performing predictive error decoding for an output from the coding unit (103); a reference picture memory (117) for holding output data from the decoding unit (105); and a motion vector detection unit (108) for detecting motion vectors on the basis of the decoded image data stored in the memory. When coding a B picture as a target picture, information indicating whether or not the target picture should be used as a reference picture when coding another picture is added as header information. Therefore, in a decoding apparatus for decoding a bit stream Bs outputted from the moving picture coding apparatus (70), management of a memory for holding the reference picture can be facilitated on the basis of the header information.

摘要： A picture coding apparatus (300) includes a motion vector estimation unit (302) and a motion compensation unit (303). The motion vector estimation unit (302) selects one method for deriving a motion vector of a block to be motion-compensated, depending on a motion vector of a block located in a corner of a decoded macroblock from among a group of blocks that compose the decoded macroblock corresponding to the current macroblock to be coded and determines the motion vector derived by the selected method for derivation to be a candidate of the motion vector of the current macroblock to be coded. The motion compensation unit (303) generates a predictive image of the block to be motion-compensated based on the estimated motion vector.
