Abstract

L'invention concerne un procédé et un appareil permettant de déterminer des paramètres de capture, et un équipement électronique. Le procédé consiste : à obtenir des informations de classification sur une image actuelle à capturer à partir d'une image de vue en direct ; à déterminer un ou plusieurs paramètres de capture de l'image à capturer à partir d'une bibliothèque de paramètres pré-mémorisés en fonction des informations de classification concernant l'image à capturer ; et à afficher le ou les paramètres de capture de l'image à capturer, de façon à recommander les paramètres de capture à un utilisateur. Par conséquent, l'utilisateur est en mesure d'obtenir rapidement des paramètres de capture précis et personnalisés, de telle sorte que l'acquisition ou la détermination des paramètres de capture est plus intelligente, et les expériences d'utilisateurs sont considérablement améliorées.
