Abstract

"MéTODO DE DERIVAçãO DO VETOR DE MOVIMENTO, MéTODO DE CODIFICAçãO DE IMAGEM ANIMADA E MéTODO DE DECODIFICAçãO DE IMAGEM ANIMADA". Uma unidade de derivação do vetor de movimento (11) inclui uma unidade de comparação (20) para comparar um parâmetro TR1 para um vetor de referência com um valor predeterminado para determinar se ele excede ou não o valor predeterminado, uma unidade de comutação (21) para alternar a seleção entre o valor máximo de um parâmetro pré armazenado TR e o parâmetro TR1 de acordo com o resultado da comparação pela unidade de comparação (20), uma tabela de parâmetro de multiplicador (para multiplicadores) (22) e uma tabela de parâmetro de multiplicador (para divisores) (24) para associar o parâmetro TR1 com um valor aproximado ao valor inverso (1/TR1) desse parâmetro TR1.
