    • There are provided an apparatus and a method for executing calculation of a global motion vector (GMV) with a high degree of reliability. Local motion vectors (LMV) corresponding to blocks and block weights as reliability indicators of the LMVs of the respective blocks are calculated, and the global motion vector (GMV) is calculated on the basis of the block weights. By calculating a degree of reliability of the local motion vector (LMV) corresponding to each block of a target block and near-field blocks adjacent to the target block and a degree of similarity between the local motion vectors (LMV) of the target block and each near-field block, the block weight is calculated through arithmetic processing to which the degree of reliability and the degree of similarity are applied. With the present configuration, it is possible to efficiently calculate the global motion vector (GMV) with a high degree of reliability.
    • 提供了以高可靠性执行全局运动矢量(GMV)的计算的装置和方法。 计算对应于块和块权重的局部运动矢量(LMV)作为相应块的LMV的可靠性指示符,并且基于块权重来计算全局运动矢量(GMV)。 通过计算与目标块的每个块和与目标块相邻的近场块对应的局部运动矢量(LMV)的可靠度和目标块的局部运动矢量(LMV)之间的相似程度,以及 每个近场块,通过应用可靠度和相似度的算术处理来计算块权重。 利用本构造,可以高度可靠地有效地计算全局运动矢量(GMV)。
