Abstract

Un método ajustar un objetivo de auto-exposición en una operación de auto-exposición en una secuencia de imágenes, tal como una secuencia de imágenes infrarrojas. El método comprende: obtener un histograma de al menos una de las imágenes; aplicar una tabla de histograma cargado al histograma para obtener depósitos de histograma cargados, en donde al menos algunos de los depósitos en el histograma que contiene píxeles saturados se les asignan un valor de carga superior y al menos algunos de los depósitos en el histograma que contiene píxeles insaturados se les asignan un valor de carga inferior, y sumar los depósitos de histograma cargado para obtener una clasificación de saturación y reducir un objetivo de auto-exposición para una operación de auto-exposición cuando la clasificación de saturación excede un valor de umbral final, y aumentar el objetivo de auto-exposición cuando la clasificación de saturación está por abajo del primer valor de umbral y la imagen es subexpuesta.
