Abstract
aparelho de decodificação de imagem, método de decodificação de imagem, e meio de armazenamento legível por computador não transitório. a presente invenção refere-se a uma unidade de decodificação que decodifica dados correspondentes a um primeiro arranjo de coeficientes quantizados incluindo um arranjo n × m de coeficientes quantizados correspondentes a um primeiro bloco e dados correspondentes a um segundo arranjo de coeficientes quantizados inclu-indo um arranjo n x m de coeficientes quantizados correspondentes a um segundo bloco. uma unidade de quantização inversa deriva um primeiro arranjo de coeficien-tes de transformação ortogonal a partir do número de um primeiro arranjo de coeficientes quantizados usando pelo menos uma primeira matriz de quantização de um arranjo de elementos n × m, e deriva um segundo arranjo de coeficientes de transformação ortogonal a partir do segundo arranjo de coeficientes quantizados usando pelo menos uma segunda matriz de quantização de um arranjo de elementos n × m. uma unidade de transformação ortogonal inversa executa a transformação ortogonal inversa no primeiro arranjo de coeficientes de transformação ortogonal para gerar um arranjo de pixels p × q de primeiros residuais de predição, e realiza transformação ortogonal inversa no segundo arranjo de coeficientes de transformação ortogonal para gerar um arranjo de pixels n × m de segundos residuais de predição.
