Color gamut adjusting method and system of display device

Abstract

The invention discloses a color gamut adjusting method and a color gamut adjusting system of a display device. The color gamut adjusting method of the display device comprises the following steps that a data processing device acquires the chroma and luminance information of the display device; the data processing device generates a search table corresponding to various color gamut modes according to the chroma and luminance information of the display device, and a mapping relation table of the various color gamut modes and various application scenes; the display device acquires the application scene selected by a user; the display device calls the search table corresponding to the color gamut mode matched with the application scene selected by the user in the data processing device, and converts the input image data into target output image data. According to the method and the system, the corresponding color gamut mode can be flexibly selected according to the application scene selected by a user, thus the display of the display device for the optimal color gamut mode under the application scene is realized, and the color distortion during image display is reduced.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a color gamut adjustment method and a color gamut adjustment system of a display device. Background technique [0002] With the development of information technology, the application of display devices is becoming more and more popular. The price of the display device is getting lower and lower, and the performance of the display device is also getting better and better. Common display devices include liquid crystal displays, OLED displays, plasma displays, projectors, and the like. [0003] When the above-mentioned display device intends to play different types of input image signals, the optimal display color gamuts corresponding to different types of input image signals are different. If the color gamut range of the input image signal is different from the color gamut range of the display device, then when the display When the device displays the ...

Problems solved by technology

[0003] When the above-mentioned display device intends to play different types of input image signals, the optimal display color gamuts corresponding to different types of input image signals are different. If the color gamut range of the input image signal is different from the color gamut range of the display device, then when the display When the device displays the input image, the color of the image will be distorted, and the image color of the object cannot be truly displayed

Therefore, it is not possible to match different color gamut modes based on different application scenarios or different types of input image signals in the prior art
