Abstract
A generated bit amount of filter coefficients of an adaptive interpolation filter is reduced. A video encoding apparatus using motion compensation includes: a motion detection unit which performs motion search to acquire a motion vector; an interpolation filter coefficient deriving unit which calculates interpolation filter coefficients used for interpolation of a decimal-precision pixel using the motion vector; an interpolation unit which performs the interpolation of the decimal-precision pixel using the interpolation filter coefficients and the motion vector and performs encoding, a parameter selection unit which selects a parameter with which a generated bit amount of the interpolation filter coefficients is minimized from among a plurality of designated parameters in parameters used for entropy encoding of the interpolation filter coefficients, and an encoding processing unit which encodes the selected parameter and the calculated interpolation filter coefficients and outputs an encoded parameter and encoded interpolation filter coefficients.
