    摘要： In expansion and reduction of the size of a macroblock in a moving image encoding, a compression ratio falls because an information amount for describing size information of the macroblock increases. An image decoding device includes a CU dividing unit and a CU-size storing unit. The CU-size storing unit has stored therein size information of an encoded CU in an encoding target picture to be stored and size information of all CUs in preceding and following pictures used for prediction. The CU dividing unit predicts a CU size in an encoding target position using the CU size information stored in the CU-size storing unit and determines a CU size of a final encoding target CU.

    摘要： A motion picture recording apparatus that includes a similar-motion-area setup unit which sets up blocks having a similar motion vector as a similar motion area, the similar motion vector being included in motion vectors calculated by a block-based motion search unit. The recording apparatus also includes a representative-motion-vector calculation unit which calculates a representative motion vector by use of a motion vector provided by each block included in the similar motion area. The recording apparatus further includes a selection unit which selects either the representative motion vector or the motion vector provided by each block, which is to be used for each block in the similar motion area. The recording apparatus also includes an encoder which performs coding processing using the selected motion vector and a prediction picture, for each block in the similar motion area.

    摘要： In methods in which coding is performed by switching, per area, between a predicted image generated by an existing coding standard and an image newly generated by performing motion estimation between decoded images, it is necessary to further provide determination information as to which image is to be used, which may in some cases result in compression efficiency that is inferior to those of conventional standards depending on the input video. By determining whether a predicted image generated by an existing coding standard is to be used or an image newly generated by performing motion estimation between decoded images is to be used based on coding information within the frame to be coded or within a previously coded frame, the need for such determination information is obviated to improve compression efficiency.

    摘要： For the purpose of providing an image encoding technique for reducing the amount of codes, in inter prediction in which motion search is performed by using a block obtained by dividing an input image and a reference image, the motion vector of the block is predicted by selecting from the motion vectors of the surrounding blocks. Further, in the method of calculating a differential vector and then performing encoding, the number or positions of candidate blocks from which a prediction vector is selected are changed block by block or frame by frame and thereby adaptive and efficient video image compression is performed.
