Abstract
(EN) A white balance adjustment method and apparatus (100), and an electronic device. The method comprises: acquiring a first image parameter of a panel to be tested (S10); acquiring a white balance compensation coefficient of said panel (S20); acquiring first target brightness of said panel by using a gamma value of said panel as a first threshold (S30); acquiring second target brightness of said panel (S40); and acquiring, according to the second target brightness of said panel, a grayscale voltage corresponding to each sub-pixel of said panel (S50).
(FR) Procédé et appareil d'ajustement de balance des blancs (100), et dispositif électronique. Le procédé consiste à : acquérir un premier paramètre d'image d'un panneau à tester (S10) ; acquérir un coefficient de compensation de balance des blancs dudit panneau (S20) ; acquérir une première luminosité cible dudit panneau en utilisant une valeur gamma dudit panneau en tant que premier seuil (S30) ; acquérir une seconde luminosité cible dudit panneau (S40) ; et acquérir, en fonction de la seconde luminosité cible dudit panneau, une tension d'échelle de gris correspondant à chaque sous-pixel dudit panneau (S50).
(ZH) 一种白平衡调整方法及其装置(100)、电子设备,方法包括:获取待测面板的第一图像参数(S10);获取待测面板的白平衡补偿系数(S20);使待测面板的伽马值为第一阈值,以获取待测面板的第一目标亮度(S30);以及,获取待测面板的第二目标亮度(S40);根据待测面板的第二目标亮度,以获取待测面板各子像素对应的灰阶电压(S50)。
