Abstract

abstract? a method for decoding an image, according to the present invention, comprises the steps of: receiving image information that corresponds to a block to be decoded; performing entropy-decoding with respect to the image information that is received; deciding a transform skip mode of the block to be decoded from a plurality of transform skip mode candidates, based on the image information that is entropy-decoded; and reverse-transforming the block to be decoded based on the transform skip mode that is decided. __________________________________________________________________________ tradução resumo resumo patente de invenção: "método e aparelho para codificação/decodificação de imagem". um método para decodificação de uma imagem, de acordo com a presente invenção, compreende as etapas de: receber informação de imagem que corresponde a um bloco a ser decodificado; realizar a decodificação por entropia com relação à informação de imagem que é recebida; decidir um modo de pulo de transformação do bloco a ser decodificado a partir de uma pluralidade de candidatos a modo de pulo de transformação, com base na informação de imagem que é decodificada por entropia, e transformar de forma inversa o bloco a ser decodificado com base no modo de pulo de transformação que é decidido.
