Title (EN) METHOD AND EQUIPMENT FOR CORRECTING VIDEO FLICKER
(FR) PROCÉDÉ ET ÉQUIPEMENT DE CORRECTION DE PAPILLOTEMENT VIDÉO
(ZH) 一种校正视频闪烁的方法及设备
Abstract:
(EN) Provided is a method and equipment for correcting video flicker. The method comprises: counting the gray scale value of a previous frame of a video image to obtain a histogram of the gray scale value of the previous frame of the video image; determining a correction weight for correcting the gray scale value of a next frame of the video image according to the histogram; and correcting the gray scale value of the next frame of the video image according to the correction weight.
(FR) L'invention concerne un procédé et un équipement de correction de papillotement vidéo. Le procédé consiste à: mesurer la valeur d'échelle de gris d'une trame précédente d'une image vidéo afin d'obtenir un histogramme de cette valeur; à déterminer un poids de correction afin de corriger la valeur d'échelle de gris d'une trame suivante de l'image vidéo en fonction de l'histogramme; et à corriger la valeur d'échelle de gris de la trame suivante de l'image vidéo en fonction du poids de correction.
(ZH) 提供了一种校正视频闪烁的方法及设备。所述方法包括:统计上一帧视频图像的灰度值,得到所述上一帧视频图像的灰度值的直方图;根据所述直方图,确定用于校正下一帧视频图像的灰度值的校正权重;并且根据所述校正权重,校正所述下一帧视频图像的灰度值。
