    • A moving picture scalable encoding method for predicting an upper-layer signal of high spatial resolution from the immediately lower-layer signal of a low spatial resolution by interpolation and encoding the data. Search to estimate a motion between an encoding subject image region of the upper-layer and a reference image region is conducted. For each image region of a predetermined unit, a first weighting factor based on the variation of brightness between an image region present in the same spatial position as an encoding subject image region of the immediately lower layer and the reference image region is calculated. The motion is estimated from the signal generated by correcting the decoded signal of the reference image region with the first weighting factor and used as an estimating signal to calculate the motion vector. A second weighting factor based on the variation of brightness between the reference image region specified by the motion vector and an image region present in the same spatial region as an encoding subject image region in the immediately-lower layer is calculated. A compensation signal for motion compensation generated by correcting the decoded signal of the reference image region with the second weight factor is used as a prediction signal of the encoding subject image region.
    • 一种用于通过插值和数据编码从低空间分辨率的立即低层信号预测高空间分辨率的上层信号的运动图像可分级编码方法。 进行搜索以估计上层的编码对象图像区域和参考图像区域之间的运动。 对于预定单元的每个图像区域,计算基于与紧邻下层的编码对象图像区域相同的空间位置存在的图像区域与参考图像区域之间的亮度变化的第一加权因子。 根据通过用第一加权因子校正参考图像区域的解码信号而生成的信号来估计运动,并将其用作估计信号以计算运动矢量。 计算基于由运动矢量指定的参考图像区域与存在于与紧邻下层中的编码对象图像区域相同的空间区域中的图像区域之间的亮度变化的第二加权因子。 将用于通过用第二加权因子校正参考图像区域的解码信号而产生的用于运动补偿的补偿信号用作编码对象图像区域的预测信号。
