Abstract

Un sistema de cámara es configurado para capturar, por medio de una pluralidad de cámaras, la información de imagen de 360 grados de un área local, al menos una porción de la cual se encuentra en estéreo. El sistema de cámara determina los ajustes respectivos de exposición para la pluralidad de cámaras. Una velocidad mínima de obturador y una velocidad máxima de obturador son determinadas a partir de los ajustes determinados de exposición. Un conjunto de ajustes de exposición de prueba es determinado utilizando las velocidades determinadas mínima y máxima de obturador. Un conjunto de imágenes de prueba es capturado utilizando la pluralidad de cámaras en cada ajuste de exposición de prueba en el conjunto de ajustes de exposición de prueba. Cada conjunto de imágenes de prueba incluye imágenes de cada una de la pluralidad de cámaras que son capturadas utilizando un mismo ajuste de exposición de prueba respectiva. Un ajuste de exposición global es seleccionado en función de los conjuntos capturados de imágenes de prueba. El ajuste seleccionado de exposición global es aplicado a la pluralidad de cámaras.
