Embodiment Construction

[0053] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0054] The main solution of the embodiment of the present invention is:

[0055] The existing display color gamut is usually larger than the transmission color gamut, causing color distortion and affecting the display effect of the display, or the rough matching between the transmission color gamut and the display color gamut through the conversion matrix cannot truly restore the color of the source end.

[0056] The present invention acquires the image data to be matched at the source end; establishes a preliminary matching relationship between the image data to be matched and the image data to be output at the display end according to the R, G, and B coordinates of the source end and the R, G, and B coordinates of the display end; The preliminary matching relationship obtains the preliminary data of the image to be ou...

Abstract

The invention discloses a color gamut matching method comprising the following steps: obtaining to-be-matched image data from a signal source end; building a primary matching relation between the to-be-matched image data and to-be-outputted image data of a display end according to the color gamut data coordinates of the signal source end and color gamut data coordinates of the display end; obtaining to-be-outputted image primary data of the display end according to the primary matching relation; accurately matching the image primary data that is to-be-outputted on the display end according toa 3D search table, thus obtaining image accurate data to be displayed on the display end. The invention also discloses a device, a display terminal and a readable storage medium, thus solving the color gamut color distortion, and improving the display effect of the display device.

Description

technical field [0001] The present invention relates to the technical field of color gamut, in particular to a color gamut matching method, device, display terminal and readable storage medium. Background technique [0002] Color gamut refers to the range of color performance, which can be divided into display device color gamut and image color gamut. Different systems or devices have large and small color gamuts. Systems and devices with large color gamuts can display more colors. Systems and devices with a small color gamut can display relatively few colors. Similarly, the image colors at the source end are displayed on different display devices, and the displayed colors are different. [0003] The color transfer of the radio and television system is mainly from the transmission color gamut to the display color gamut. The transmission color gamut is the image color space of the source end transmitted by the radio and television system. The display color gamut is the color ...
