Abstract

"método para intensificar de forma adaptativa uma cor, equipamento para intensificar de forma adaptativa a cor de uma imagem e meio de gravação legível em computador". método e equipamento para intensificar de forma adaptativa uma cor de uma imagem são proporcionados. o equipamento inclui uma unidade de derivação de componente de saturação, um calculador da variável que determina a função de intensificação de saturação, uma unidade de intensificação de saturação e uma unidade sintetizadora do componente de saturação. a unidade de derivação do componente de saturação deriva um componente de saturação a partir de uma imagem de entrada. o calculador da variável que determina a função de intensificação de saturação determina uma função de intensificação de saturação usada para intensificar a saturação da imagem de entrada com base em um predeterminado valor de referência. a unidade de intensificação de saturação altera o derivado componente de saturação usando a função de intensificação de saturação. a unidade sintetizadora do componente de saturação sintetiza o alterado componente de saturação e outros componentes da imagem de entrada e gera uma imagem de saída com base nos componentes sintetizados.
