Claim Text:
1. A moving picture encoding device that divides an encoding target picture into a plurality of target blocks and performs prediction encoding in which a prediction signal is generated for a respective target block with reference to one reference picture of a plurality of reference pictures, the moving picture encoding device comprising: a processor; a prediction signal generation method controller unit that is executable by the processor to select one of a plurality of processes from each of a plurality of respective types of predetermined processes to determine, for each of the respective reference pictures, a processing method, the processing method to be performed to generate a prediction signal, and also executable to determine, for each of the respective target blocks, a motion vector and one reference picture, the determined one reference picture having a corresponding reference list number identifying the determined one reference picture, the plurality of types of predetermined processes comprising: pixel interpolation processes indicative of integer pixel accuracy or a level of fractional pixel interpolation accuracy, and types of pixel interpolation filters used to generate the prediction signal with said integer pixel accuracy or said level of fractional pixel interpolation accuracy; a prediction signal generator unit that is executable by the processor to process the determined one reference picture, using the determined processing method, to generate a prediction signal for the respective target blocks; and an encoder unit that is executable by the processor to encode, for each of the respective target blocks, information on the determined processing method in association with the reference list number identifying the determined one reference picture, and motion vector information.
