Image prediction encoding device 100 to efficiently generate a prediction signal with small additional information and small computational amount is, generating a prediction signal for the target pixel signals of the one individual subject region of the plurality of regions divided by the block divider 102, It includes a prediction signal generator 103, and a group behavior estimator 113, a subtractor 105 for generating a residual signal between the prediction signal and the target pixel signal to search for the motion vector to generate the prediction signal from the reproduction signal do. Prediction signal generator 103, a group (旣) determining a partial area in the search area of the reproduced signal, and this second species candidate prediction signal more than one generation, and the plurality of the second kind from the basis of the motion vector have the candidate prediction signal and the motion vector type 1 candidate prediction for generating a prediction signal by processing using a predetermined candidate prediction signal synthesis signal synthesizer 203 is generated based on.
