Color gamut matching method, device, display terminal and readable storage medium

A display terminal, comprising a display, a memory, a processor, and a color gamut matching program stored on the memory and executable on the processor, the color gamut matching program, when executed by the processor, implements the following operations:

• obtaining image data to be matched of a source terminal;
• establishing a preliminary matching relationship between the image data to be matched and image data to be output of the display terminal according to color gamut data coordinates of the source terminal and color gamut data coordinates of the display terminal;
• obtaining preliminary image data to be output of the display terminal according to the preliminary matching relationship;
• and
• accurately matching the preliminary image data to be output of the display terminal according to a 3D look-up table to obtain accurate image data to be displayed of the display terminal.

A readable storage medium, wherein a color gamut matching program is stored on the readable storage medium, and the color gamut matching program, when executed by a processor, implements the following operations:

• obtaining image data to be matched of a source terminal;
• establishing a preliminary matching relationship between the image data to be matched and image data to be output of a display terminal according to color gamut data coordinates of the source terminal and color gamut data coordinates of the display terminal;
• obtaining preliminary image data to be output of the display terminal according to the preliminary matching relationship;
• and
• accurately matching the preliminary image data to be output of the display terminal according to a 3D look-up table to obtain accurate image data to be displayed of the display terminal.
