    • An image predictive encoding device can efficiently encode an image, while suppressing an increase in prediction information and reducing the prediction error of a target block. In an image predictive encoding device, according to one embodiment, to produce a prediction signal of a partition in a target region, it is decided whether prediction information of a neighbouring region can be used. When prediction information of the neighbouring region can be used, a region width of the partition where the prediction information of the neighbouring region is used to produce the prediction signal is determined. The prediction signal of the target region is produced from a reconstructed signal based on at least one of the region width, the prediction information of the target region, and the prediction information of the neighbouring region. The prediction information, information identifying the region width, and a residual signal are encoded.
    • 图像预测编码装置可以在抑制预测信息的增加并减少目标块的预测误差的同时有效地编码图像。 在根据一个实施例的图像预测编码装置中,为了产生目标区域中的分区的预测信号,确定是否可以使用相邻区域的预测信息。 当可以使用相邻区域的预测信息时,确定使用相邻区域的预测信息的分区的区域宽度来产生预测信号。 基于区域宽度,目标区域的预测信息和相邻区域的预测信息中的至少一个,从重建信号产生目标区域的预测信号。 编码预测信息,识别区域宽度的信息和残留信号。
