Abstract
MÉTODO PARA AJUSTE DE ALVO DE EXPOSIÇÃO AUTOMÁTICA, MÉTODO PARA GERAR MÁSCARA DE PIXELS SATURADOS E APARELHO DE IMAGEAMENTO. A presente invenção refere-se a um método que ajusta um alvo de exposição automática em uma operação de exposição automática em uma sequência de imagens, tal como uma sequência de imagens infravermelhas. O método compreende: obter um histograma de pelo menos uma das imagens; aplicar uma tabela de histograma ponderado ao histograma para obter caixas de histograma ponderado, sendo que pelo menos a algumas caixas no histograma que contenham pixels saturados é atribuído um valor de ponde ração maior, e pelo menos a algumas caixas no histograma que contenham pixels insaturados é atribuído um valor de ponderação menor, e somar as caixas de histograma ponderado para obter um ponto de saturação e diminuir um alvo de exposição automática para uma operação de exposição automática quando o ponto de saturação excede um primeiro valor limite, e aumentar o alvo de exposição automática quando o ponto de saturação está abaixo do primeiro valor limite e a imagem é subexposta.
