Abstract
It is a purpose of the present invention to provide a video encoding apparatus and a video decoding apparatus which are capable of providing real-time processing having improved coding performance. A video encoding apparatus AA includes an inter-encoding predicted value generating unit 2 configured to receive, as input signals, an input image a, a local decoded value d acquired from an encoded block, prediction direction information e acquired from the encoded block, and interpolation filter initial control information b. The inter-encoding predicted value generating unit 2 includes a filter control unit 21. The filter control unit 21 extracts the tap size N of the interpolation filter and the initial value c0(i,j) of the filter coefficient of the interpolation filter from the interpolation filter initial control information b, and uses the initial value c0(i,j) of the filter coefficient of the interpolation filter as the filter coefficient c(i,j) of the interpolation filter.
