Abstract

"APARELHO E MéTODO PARA CODIFICAR IMAGEM EM MOVIMENTO". A presente invenção se refere a um aparelho e método para codificar imagens em movimento que empregam transformada de pequena onda. Em particular, a presente invenção realiza a codificação intra-quadro por meio da transformação de sinal de entrada de vídeo, sinal RGB, em sinal de compressão de objeto de imagem em movimento (YUV), pela obtenção de dados através da transformada de pequena onda, e quantificação do sinal de compressão de objeto de imagem em movimento transformado do tamanho certo e, então, pela emissão dos dados após a codificação de entropia. Da mesma forma, a presente invenção realiza a codificação inter-quadro.
