Image processing apparatus and image processing method

Abstract

An image processing apparatus for decoding an image coded in coding processes including (i) prediction on at least one prediction unit (PU) and (ii) frequency transform on transform units (TUs) included in a region including the at least one PU includes a processing unit configured to perform image processing for a predictive image of the at least one PU, depending on a transform order predetermined for the TUs.
