PURPOSE: An intra prediction method is provided to make a compression rate and a reproduction rate highly efficient when a video is encoded or decoded. CONSTITUTION: A reference pixel generating unit(151) generates reference pixels. A reference pixel filtering unit(152) presently adaptively filters the reference pixels of a current prediction unit. A prediction block generating unit(153) generates a prediction block corresponding to an intra prediction mode. A prediction block filtering unit(154) adaptively filters the generated prediction block according to the intra prediction mode. A prediction mode encoding unit(156) encodes the intra prediction mode of a determined current prediction unit.
