Color temperature adjusting method based on screen brightness and color temperature adjusting device thereof and equipment

Abstract

The invention discloses a color temperature adjusting method based on screen brightness and a color temperature adjusting device thereof and equipment. The method comprises the steps that the current screen brightness after performing blue light filtering operation on the screen is detected; and the RGB spectral energy reconstruction proportion corresponding to the current screen brightness and the target color temperature required to be met is determined according to RGB spectral energy distribution information learnt in advance, and the RGB spectral energy of the screen is adjusted according to the RGB spectral energy reconstruction proportion so that the RGB spectral energy of the energy after blue light filtering operation is enabled to meet the target color temperature. Therefore, the color temperature and the corresponding screen brightness are correspondingly set so that drift of the color temperature can be avoided, the adjusting effect of the color temperature is enabled to meet the user expectation and the visual experience of the user can be enhanced.

Description

technical field [0001] The present application relates to the technical field of screen display, and in particular to a method, device and equipment for adjusting color temperature based on screen brightness. Background technique [0002] At present, the screens of terminal devices are mainly composed of RGB three colors superimposed to present different colors, among which B is high-energy short-wave blue light. Excessive blue light will cause eye diseases and macular degeneration. Therefore, many manufacturers use the method of filtering out part of the blue light to protect the eye health of users. [0003] However, after filtering a part of the blue light B, since the brightness of the screen is composed of the ratio of RGB, when adjusting the color temperature to filter out part of the blue light, in addition to the significant change in the color of the screen, the brightness of the screen will also change accordingly, and in the actual operation process In , when the...

[0003] However, after filtering a part of the blue light B, since the brightness of the screen is composed of the ratio of RGB, when adjusting the color temperature to filter out part of the blue light, in addition to the significant change in the color of the screen, the brightness of the screen will also change accordingly, and in the actual operation process When the brightness of the screen changes, the color temperature of the screen will also change at the same time. The maximum color temperature change can reach 600-700K, resulting in the result of the color temperature adjustment not matching the expectation of the color temperature adjustment, and the error is large.
