Abstract

Un método para estimar el contenido de clorofila de una hoja (12), en donde el método comprende: proporcionar un dispositivo (10), en donde el dispositivo comprende: un dispositivo informático móvil (14) que comprende una cámara digital (16); y un periférico (18) unido de manera extraíble al dispositivo informático móvil, en donde el periférico comprende una fuente de luz (20) alineada con la cámara digital cuando el periférico está unido de manera extraíble al dispositivo informático móvil de modo tal que la fuente de luz (20) puede iluminar una lente de la cámara digital (16), en donde el periférico proporciona un espacio (19) entre la fuente de luz (20) y la cámara digital (16); capturar con la cámara digital (16) una primera imagen (34a) de la fuente de luz encendida sin la hoja (12) interpuesta entre la cámara digital y la fuente de luz; recuperar datos de exposición de la primera imagen; capturar con la cámara digital una segunda imagen (34b) con la hoja interpuesta entre la cámara digital y la fuente de luz encendida; recuperar datos de exposición de la segunda imagen; y, mediante el uso de un procesador, estimar el contenido de clorofila de la hoja en función de los datos de exposición recuperados de la primera y segunda imagen, en donde los datos de exposición incluyen al menos uno de tiempo de exposición, número F y valor ISO.
