Abstract

The invention discloses a color cast correction information setting method and device, an image processing method and device and display equipment, relates to the technical field of image processing,and aims to reduce the color cast of an image displayed by a display panel. The setting method comprises the following steps: receiving pixel arrangement information of a first display area and at least one second display area, and obtaining pixel brightness adjustment parameters of each color in each second display area according to the pixel arrangement information of the first display area andthe pixel arrangement information of each second display area; and obtaining a correction power supply signal voltage expression of each color pixel in each second display area as color cast correction information according to the brightness adjustment parameter of each color pixel in each second display area and the corresponding color pixel driving information. The processing method applies theset correction power supply signal voltage expression. The color cast correction information setting method provided by the invention is used for image processing.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a color shift correction method and device, an image processing method and device, and a display device. Background technique [0002] With the development of display technology, electronic display products such as mobile phones and tablet computers have more and more functions, which brings a higher user experience to users. For example, existing electronic display products such as mobile phones and tablet computers are equipped with components such as front cameras and earpieces to improve user experience. However, components such as front cameras and earpieces limit the screen-to-body ratio of electronic display products to a certain extent. [0003] In view of the above problems, when making a display panel, the pixel area included in the display panel is divided into a low-density pixel area and a normal-density pixel area, and components such as a front ca...
