Abstract

A video encoding device uses fractional pixel accuracy motion compensation prediction based on a DCT interpolation filter, and includes: a fractional pixel accuracy motion vector search unit 10 for estimating a fractional pixel accuracy motion vector using an interpolation filter 11 different from a DCT interpolation filter 21; and a fractional pixel accuracy motion compensation prediction signal updating unit 20 for updating a prediction signal of a position of the fractional pixel accuracy motion vector estimated by the fractional pixel accuracy motion vector search unit 10, with a prediction signal based on the DCT interpolation filter 21.
