Abstract
uma modalidade da presente invenção estabelece uma técnica para corrigir valores de cor. a técnica inclui amostrar abaixo os primeiros valores de espaço de cor para gerar valores de espaço de cor amostrados abaixo e amostrar acima os valores de espaço de cor amostrados abaixo para gerar os segundos valores de espaço de cor. a técnica inclui ainda a modificação de pelo menos um valor de componente incluído nos valores de espaço de cor amostrados abaixo com base em um primeiro valor de componente incluído nos primeiros valores de espaço de cor, um segundo valor de componente incluído nos segundos valores de espaço de cor, e uma aproximação de uma função de transferência não linear.
