Embodiment Construction

[0029] The terms used in the embodiments of the present application are only used to explain specific embodiments of the present application, and are not intended to limit the present application.

[0030] Before introducing the embodiments of the present application, firstly, the problems of the prior art are briefly described.

[0031] Table 1

[0032]

[0033] For example, as shown in Table 1, Table 1 is a color mapping relationship for implementing color correction in the prior art, R, G, and B respectively represent the intensity values ​​of red, green, and blue, and the input value of R is 0 When , the output value of R is 3, when the input value of G is 0, the output value of G is 0, when the input value of B is 0, the output value of B is 0, and so on, R, G, and B respectively have respective mapping relationships. If the RGB input value of a pixel is 3,1,0, its output value will be 9,2,0. At this time, if the input value of R becomes 2, but G and B remain unchang...

Abstract

The embodiment of the invention provides a color correction method, an AP chip, a terminal and a storage medium, relates to the technical field of display, and can improve the color consistency of a display picture. The color correction method is executed by the terminal and comprises the steps of obtaining to-be-displayed data and a first 3D-LUT, wherein the first 3D-LUT reflects the mapping relation between the display color of a display screen of the terminal and the target display color; acquiring first corrected data to be displayed according to the data to be displayed and the first 3D-LUT; and indicating to display according to the first corrected to-be-displayed data. The technical scheme is mainly used for color correction of the display panel.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a color correction method, an AP chip, a terminal and a storage medium. Background technique [0002] With the development of display technology, the requirements for the display effect of the display screen on the terminal are getting higher and higher, and the pursuit of high-quality restoration effect has become a mainstream trend. However, the current terminals, such as mobile phones, even the same model of mobile phones will give people different subjective feelings under the white screen input. Different parameter corrections may introduce the problem of inconsistent display effects. At present, in addition to improving the consistency of the display effect through the design of the display panel itself, subsequent software corrections, such as gamma correction, will be performed on each display panel on the production line. The whole process of software calibr...
