Title: (EN) PREDICTION IMAGE GENERATION DEVICE, MOVING IMAGE DECODING DEVICE, AND MOVING IMAGE ENCODING DEVICE
(ZH) 预测图像生成装置、运动图像解码装置、以及运动图像编码装置
Abstract: front page image
(EN) In order to improve encoding efficiency, a movement compensation filter unit (30912) for acting on an image to which a movement vector has been applied and which is obtained by causing the movement vector to act on a reference image causes a filter coefficient mcFilter[i][k] designated by a phase (i) and a filter coefficient position (k) to act on the image to which a movement vector has been applied, and a filter coefficient calculated using a filter coefficient mcFilter[p][k] (p not equal to i) and a filter coefficient mcFilter[q][k] (q not equal to i) are included in the filter coefficientmcFilter[i][k].
(ZH) 本发明提高编码效率。对使运动矢量作用于参照图像而获得的应用完运动矢量的图像发挥作用的运动补偿滤波部(30912)使由相位(i)和滤波系数位置(k)指定的滤波系数mcFilter[i][k]发挥作用,滤波系数mcFilter[i][k]中包含使用滤波系数mcFilter[p][k](p≠i)以及滤波系数mcFilter[q][k](q≠i)计算出的滤波系数。
