Embodiment Construction

[0035] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0036] refer to figure 1 , in the first embodiment of the present invention, the color gamut mapping method includes the following steps:

[0037] Step S10, obtaining the pixel value of the image signal to be sent at the source end and the pixel value of the image signal to be output at the display end respectively;

[0038] Color gamut refers to the area formed by the number of colors that can be expressed by a certain color representation mode. It is a method of encoding colors. Common color modes include RGB, CMYK, and Lab. The pixel value of the image signal to be sent at the source end may be a color gamut pixel value in any one of the above three color modes. It can be understood that the pixel value of the image signal to be output on the display terminal may also be a color gamut pixel value in any one of th...

Abstract

The invention discloses a colour gamut mapping method, a display terminal, and a computer readable storage medium. The colour gamut mapping method comprises: a to-be-sent image signal pixel value of a source terminal and a to-be-outputted image signal pixel value of a display terminal are obtained respectively; according to a preset algorithm, a mapping relationship between the to-be-sent image signal pixel value of the source terminal and the to-be-outputted image signal pixel value of the display terminal is established; and on the basis of the mapping relationship, a to-be-displayed image signal pixel value of the display terminal is obtained and the obtained to-be-displayed image signal pixel value is transformed into an image signal for displaying by the display terminal. Therefore, a technical problem that the display effect of the display device is affected because of distortion of the hue of the display color gamut can be solved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a color gamut mapping method, a display terminal and a computer-readable storage medium. Background technique [0002] The expressive ability of image color can be measured by color gamut. Color gamut is a method of encoding colors, and also refers to the sum of colors that a technical system can produce, such as NTSC, BT709, BT2020 color gamut, etc. Different systems or devices have different color gamuts. A device or system with a large color gamut can display more colors, while a device or system with a small color gamut can display relatively fewer colors. The same signal source is displayed on different models of monitors, and the color performance is often different. [0003] The color transfer of the broadcast TV system is mainly from the transmission color gamut to the display color gamut. The transmission color gamut is the color space transmitted by th...
