Abstract

"MéTODO E SISTEMA PARA COMPRIMIR UM BLOCO DE IMAGEM, PARA CODIFICAR UMA IMAGEM, PARA PROCESSAR UMA REPRESENTAçãO COMPRIMIDA DE UM BLOCO DE IMAGEM, E PARA DECODIFICAR UMA IMAGEM CODIFICADA, E, REPRESENTAçãO DE SINAL DE UM BLOCO DE IMAGEM". Em um esquema de codificação de imagem, um imagem de entrada é decomposta em vários blocos de imagem (600) compreendendo múltiplos elementos de imagem (610), por exemplo pixéis ou texéis. Os blocos de imagem (600) são então codificados em representações de bloco codificadas (700). Tal representação de bloco (700) compreende uma palavra-código de cor (710), uma palavra-código de intensidade (720) e uma seqüência (730) de representações de intensidade. A palavra-código de cor (710) é uma representação das cores dos elementos de imagem (610) do bloco (600). A palavra-código de intensidade (720) é uma representação de um conjunto de múltiplos modificadores de intensidade para modificar a intensidade dos elementos de imagem (610) no bloco (600). A seqüência de representação (730) compreende uma representação de intensidade para cada elemento de imagem (610) no bloco (600), onde uma representação identifica um de modificadores de intensidade no conjunto de modificadores de intensidade. Durante decodificação, as palavras-código de cor e intensidade (710, 720) e representações de intensidade (730) são usadas para gerar uma representação decodificada dos elementos de imagem (610) no bloco (600).
