A moving picture encoding device (100) includes: a prediction signal generation method controller (102) that determines a processing method to be performed on a reference picture for generating a prediction signal on each of a plurality of reference pictures by combining a predetermined plurality of processes, and determines a motion vector and a reference picture on each target block by performing motion prediction for every target block; a prediction signal generator (104) that generates the prediction signal for the target block by performing processing on the reference picture based on the processing method to be performed on the reference picture for the target block; and an encoder (107) that encodes information on the processing method on each reference picture together with a reference list number identifying a reference picture and motion vector information of every target block.
