Abstract

a presente revelação refere-se, de modo geral, a um método e dispositivo de codificação de uma imagem colorida que tem componentes de cor (ec) que compreende obter (11) um componente de luminância (l) e dois componentes de crominância (c1, c2) a partir da imagem colorida a ser codificada. em que o método para codificar uma imagem colorida que tem componentes de cor compreende obter pelo menos um componente de crominância a partir da imagem colorida a ser codificada, sendo que o método é distinguido pelo fato de que compreende adicionalmente: - determinar um primeiro fator com base no valor de cada pixel (i) do dito componente de luminância; - obter pelo menos um componente de crominância final escalonando-se o dito pelo menos um componente de crominância pelo dito primeiro fator; e - codificar (13) o dito pelo menos um componente de crominância final.
