APPARATUS AND METHOD FOR ENCODING IMAGE AND FOR DECODING IMAGE

摘要

PURPOSE: An apparatus and a method for encoding and decoding an image are provided to improve the accuracy of a prediction signal by using two excellent methods for a simple image and an image having a pattern and a noise in the generation of a prediction signal. CONSTITUTION: A first prediction block generator(182) generates a first prediction block corresponding to an encoding target block based on the values of the pixels adjacent to an encoding target block, and a second prediction block generating unit(184) generates a second prediction block corresponding to the encoding target block through a template area formed by the pixels adjacent to the encoding target block. A final prediction block generator(186) generates a final prediction block corresponding to the encoding target block, and an encoder(140) encodes the generation information and a weight value of blocks.
