Image display method, device and system

Abstract

The embodiment of the invention discloses an image display method, a device and an image display system, relates to image display and solves the problem that the prior art can not flexibly adjust the brightness and the color saturation of the image so as to improve the quality of the image. In the embodiment of the invention, the original RGB chromaticity coordinate of the image is converted into the chromaticity coordinate in target color gamut space; the chromaticity coordinate of the image is adjusted in the target color gamut space; the chromaticity coordinate adjusted in the target color gamut space is converted to the RGB color gamut space so as to obtain a target RGB chromaticity coordinate; and the image is displayed according to the target RGB chromaticity coordinate, so the brightness and / or the color saturation of the image can be flexibly adjusted, and the intensity of light source can be adjusted in real time so as to save energy.

Description

technical field [0001] The present invention relates to image display technology, in particular to an image display method, device and system. Background technique [0002] Color display using red, green and blue (RGB) primary color lasers as light sources is called laser display technology. Laser display technology has the characteristics of large color gamut, high brightness, low energy consumption, and long life. The color performance of laser display technology is about Twice that of other display technologies, the images are clear and the colors are vivid. Therefore, laser display technology has begun to be more and more widely used in televisions, micro-projectors, commercial or entertainment display systems. [0003] In the prior art, in order to further improve the color saturation and brightness of the image, to improve the quality and clarity of the image, etc., the above-mentioned processing of the image in the RGB color gamut space is usually carried out for the ...

AI Technical Summary

Problems solved by technology

[0004] However, since in the RGB color gamut space, the color saturation and brightness of the image are obtained by the three color parameters of red R, green G and blue B, so the brightness and color saturation are not independent variables, when adjusting the brightness of the image When adjusting the color saturation, it will inevitably adjust to the color saturation. Similarly, adjusting the color saturation of the image will inevitably adjust to the brightness. It is impossible to flexibly adjust the brightness and color saturation of the image to improve the quality of the image.
