摘要：
An image prediction encoding device includes a prediction signal generator that produces a prediction signal with respect to a target pixel signal of a target region that is among regions divided by a block division unit, a motion estimator that searches for a motion vector required for the production of the prediction signal from an already reproduced signal, and a subtractor that produces a residual signal indicating a difference between the prediction signal and the target pixel signal. The prediction signal generator determines a search region that is a partial region of the already reproduced signal based on the motion vector and produces one or more type 2 candidate prediction signals. The prediction signal generator includes a candidate prediction signal combining unit that produces the prediction signal by processing the type 2 candidate prediction signals and a type 1 candidate prediction signal produced based on the motion vector.
