摘要 |
An object is to efficiently depress mode information for identification of a prediction method even if there are a lot of prediction methods provided as to methods of generating intra-frame prediction signals in a pixel domain. An image prediction encoding device 10 has a block dividing unit 102, an intra-frame prediction signal generation method determining unit 105, an intra-frame prediction signal generating unit 106, a subtractor 108, a transform unit 109, a quantization unit 110, and an entropy encoding unit 115; the intra-frame prediction signal generation method determining unit 105 derives an adjacent region prediction method for generation of an intra-frame prediction signal highly correlated with pixel signals of an adjacent region, using a proximate pixel group to a target region, out of a plurality of first prediction methods, and predicts a target region prediction method for target pixel signals, based on the derived adjacent region prediction method; the intra-frame prediction signal generating unit 106 generates an intra-frame prediction signal for the target region, based on the target region prediction method. |
