Abstract
dispositivo de exibição de imagem e método de exibição de imagem. a presente invenção refere-se a um dispositivo com visor de cristal líquido, uma seção de correção de valor de saída de ld (513) incluída em uma seção de processamento de acionamento ativa por área (5) corrige os dados de led dbl obtidos por uma seção de cálculo de valor de saída de led (512) com referência a uma lut de correção de luminância (13), de forma que a luminância na área de um valor intermediário até próximo a um valor máximo se desvie a um grau mais alto. assim, mesmo se a luminância de retroiluminação for baixa (tipicamente, a luminância média de uma imagem de entrada é baixa), a razão de constraste é acentuada, prevenindo assim um salto de tom (luminância insuficiente) em níveis de tom altos derivado a uma luminância de retroiluminação insuficiente.
