摘要： 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 neighboring region can be used. When prediction information of the neighboring region can be used, a region width of the partition where the prediction information of the neighboring 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 neighboring region. The prediction information, information identifying the region width, and a residual signal are encoded.
