Abstract
(EN) The invention discloses an image processing method, an image processing device, a display device and a storage medium. The image processing method is suitable for processing a to-be-processed image to obtain a target image, and image data of the to-be-processed image comprises a gray-scale value corresponding to each basic color component in a plurality of basic color components. The image processing method comprises the following steps: determining a target color temperature; determining a target value of each basic color component corresponding to the target color temperature; determining transformation parameters of each basic color component according to the target value of each basic color component; and based on the transformation parameter of each basic color component, carrying out transformation operation on the gray-scale value corresponding to each basic color component in the image data of the to-be-processed image to obtain the image data of the target image.
(ZH) 一种图像处理方法、图像处理装置、显示装置及存储介质。该图像处理方法适用于对待处理图像进行处理以得到目标图像,其中,待处理图像的图像数据包括对应于多种基本颜色成分中的每种基本颜色成分的灰阶值。该图像处理方法包括:确定目标色温;确定目标色温对应的每种基本颜色成分的目标值;根据每种基本颜色成分的目标值,确定每种基本颜色成分的变换参数;以及基于每种基本颜色成分的变换参数,对待处理图像的图像数据中的对应于每种基本颜色成分的灰阶值进行变换操作,以得到目标图像的图像数据。
