Abstract:
1. A moving picture encoding method executed by a processor, the method comprising: performing a plurality of interpolation processings on a reference image using respective plurality of interpolation processings, each of the plurality of interpolation processings having different characteristics; detecting a motion vector having a highest encoding efficiency from a plurality of motion vectors generated for the plurality of interpolated images; and selecting an interpolation processing of said reference image that generates said motion vector having the highest encoding efficiency from said plurality of interpolation processings, wherein said interpolation processing includes filtering for realizing a shift of an amount of phase which is different from an amount of phase corresponding to a positional difference between a picture element of said reference image and a corresponding picture element of said reference image on which interpolation processing is performed when picture element values of said reference image on which interpolation processing is performed are derived from picture element values of said reference image.
