Image encoding apparatus and image encoding method that determine an encoding method, to be used for a block to be encoded, on the basis of an intra-frame-prediction evaluation value calculated using prediction errors between selected reference pixels and an input image

摘要

In an image encoding apparatus including an intra-frame prediction unit that executes intra-frame prediction regarding an input image, when locally decoded pixels are not available, pseudo reference pixels are set to calculate an intra-frame-prediction evaluation value, and a method of encoding to be used for a block to be encoded is determined on the basis of the intra-frame-prediction evaluation value.
