Abstract
(EN) Disclosed by the present application are an image processing method and apparatus, an electronic device, and a storage medium. The method comprises: acquiring video data to be processed, the video data comprising at least two images and attribute information respectively corresponding to the at least two images; using the attribute information respectively corresponding to the at least two images to determine values respectively corresponding to the at least two images so as to obtain at least two values, the values representing brightness values of ambient light when an image is photographed; on the basis of the at least two values, determining a tone mapping curve respectively corresponding to the at least two images; and using the tone mapping curve respectively corresponding to the at least two images to perform tone mapping processing on the at least two images respectively so as to obtain at least two processed images.
(FR) La présente invention concerne un procédé et un appareil de traitement d’images, un dispositif électronique et un support de stockage. Le procédé comprend : l’acquisition de données vidéo à traiter, les données vidéo comprenant au moins deux images et des informations d’attribut correspondant respectivement aux deux images ou plus ; l’utilisation des informations d’attribut correspondant respectivement aux deux images ou plus pour déterminer des valeurs correspondant respectivement aux deux images ou plus de sorte à obtenir au moins deux valeurs, les valeurs représentant des valeurs de luminosité de la lumière ambiante lorsqu’une image est photographiée ; sur la base des deux valeurs ou plus, la détermination d’une courbe mappage de teintes correspondant respectivement aux deux images ou plus ; et l’utilisation de la courbe de mappage de teintes correspondant respectivement aux deux images ou plus pour réaliser un traitement du mappage de teintes respectivement sur les deux images ou plus de sorte à obtenir au moins deux images traitées.
(ZH) 本申请公开了一种图像处理方法、装置、电子设备及存储介质。其中,方法包括:获取待处理视频数据;所述待处理视频数据包括至少两个图像以及与所述至少两个图像分别对应的属性信息;利用与所述至少两个图像分别对应的属性信息,确定与所述至少两个图像分别对应的数值,得到至少两个数值;所述数值表征拍摄图像时环境光的亮度值;基于所述至少两个数值,确定与所述至少两个图像分别对应的色调映射曲线;利用与所述至少两个图像分别对应的色调映射曲线,对所述至少两个图像分别进行色调映射处理,得到处理后的至少两个图像。
