Abstract

La presente descripción se refiere a un método y un aparato para ajustar el brillo de una pantalla, que pertenece al campo de la tecnología informática. El método incluye: adquirir mediante un sensor de luz un primer brillo de luz ambiente en un ambiente donde se localiza una terminal; detectar si el sensor de luz se orienta en dirección contraria a una fuente de luz en el ambiente; calcular un primer nivel de brillo de la luz de fondo de acuerdo con el primer brillo de la luz ambiente si el sensor de luz se orienta en dirección contraria a la fuente de luz, donde el primer nivel de brillo de la luz de fondo es superior a un segundo nivel de brillo de la luz de fondo, y el segundo nivel de brillo de la luz de fondo se calcula de acuerdo con el primer brillo de la luz ambiente cuando el sensor de luz se orienta hacia la fuente de luz; y configurar el brillo de la luz de fondo de la terminal al primer nivel de brillo de la luz de fondo. La presente descripción soluciona el problema del cálculo impreciso de un nivel de brillo de la luz de fondo de acuerdo con el brillo de la luz ambiente medido y de la función de la luz de fondo usada cuando el sensor de luz se orienta en dirección contraria a la fuente de luz debido a que el brillo de la luz ambiente medido es menor cuando el sensor de luz se orienta en dirección contraria a la fuente de luz, y logra un efecto de mejora de la precisión del nivel de brillo de la luz de fondo.
