Abstract

The embodiment of the invention discloses a method and a device for obtaining the maximum common color gamut of a display screen, which are used to obtain the maximum common color gamut of a display screen with multiple primary colors, thereby improving the display consistency of the display screen. The method for obtaining the maximum common color gamut of the display screen in the embodiment of the present invention includes: determining the color quantity of primary colors in a plurality of color gamuts, and classifying the primary colors of adjacent colors for all color points in all color gamuts according to each color; All color points that belong to the same basic color classification and do not belong to the same color gamut are determined; according to the color coordinates corresponding to the color points, the public color points that meet the conditions of not exceeding each color gamut are determined, and the color coordinates corresponding to the public color points are Boundary color coordinates of at least one color gamut; determine the maximum common color gamut according to the color coordinates corresponding to all common color points.

Description

technical field [0001] The present invention relates to the technical field of image processing, and in particular, to a method and device for obtaining the maximum common color gamut of a display screen. Background technique [0002] A display is also commonly referred to as a monitor. A monitor is an I / O device that belongs to a computer, that is, an input and output device. It is a display tool that displays a certain electronic file on the screen through a specific transmission device and then reflects it to the human eye. [0003] Most of the current display products are three-primary display screens, namely RGB (red, green and blue) three-primary colors. After a long period of development, the three-primary color display screen has become very mature. However, the display of three primary colors has not been able to truly restore the colors of nature, and the display details in some high-end fields can no longer meet the requirements. In order to make the color gamu...
