Abstract

L'invention concerne un procédé de réglage de la puissance d'une lampe infrarouge se rapportant au domaine de la photographie. Le procédé consiste : dans le processus de démarrage par un équipement photographique d'une lampe infrarouge afin de photographier une image, à acquérir un paramètre d'image de l'image photographiée, le paramètre d'image permettant d'indiquer la luminosité d'un environnement photographique actuel ; à déterminer si le paramètre d'image est situé dans une plage de paramètres prédéfinie ; et lorsque le paramètre d'image n'est pas situé dans la plage de paramètres prédéfinie, à régler la puissance de sortie de la lampe infrarouge. Étant donné qu'un paramètre d'image acquis permet d'indiquer la luminosité d'un environnement photographique, la luminosité de l'environnement photographié peut être déterminée en fonction du paramètre d'image, de telle sorte que la puissance de sortie d'une lampe infrarouge puisse être réglée de manière appropriée en fonction de la luminosité de l'environnement photographique, ce qui permet d'éviter les problèmes de consommation d'énergie relativement élevée et de génération de chaleur provoquée par un fonctionnement en permanence de la lampe infrarouge à la puissance de sortie maximale et de prolonger la durée de vie de l'équipement photographique.
