[0002] The color temperature of the screen is one of the most important criteria to measure the quality of the screen color display. The user's perception of the same color on the screen varies with the color temperature of the screen. Therefore, terminal equipment usually allows users to manually adjust the color temperature of the screen, but as the terminal With the development of intelligent technology, manual a

[0041] see figure 1 , the first embodiment of the method for adjusting the color temperature of the screen is proposed in the present invention, the method includes the following steps:
[0042] Step S10: Detect the RGB value of the pixel in the user interface of the terminal
[0043] The terminal may detect RGB values of pixels in the current user interface of the terminal in real time or at preset intervals. Preferably, when the terminal detects that the current user interface changes, the detection is performed once.
[0044] The terminal may only detect RGB values of pixels that meet preset conditions in the user interface, such as pixels in a preset area or an area specified by the user. In this embodiment, the RGB values of all pixels in the user interface are preferably detected.
[0045] The RGB value refers to the numerical value of three reference colors of red (Red), green (Green) and blue (Blue) included in a pixel, and different RGB values correspond to ...

Abstract
The invention discloses a method and device for adjusting the color temperature of a screen. The method comprises the steps: detecting an RGB value of a pixel in a user interface of a terminal; acquiring tone information of the user interface according to the RGB value; acquiring a color temperature value corresponding to the tone information of the user interface according to the preset correspondence of the color tone and the color temperature; and adjusting the color temperature of the screen according to the acquired color temperature value. By adopting the method and device, the color temperature of the screen can be dynamically adjusted by the terminal along with the variation of the user interface, so that the color temperature of the screen is matched with the user interface. When the color tone of the user interface is relatively cool, the color temperature of the screen is correspondently lowered, and the color is enabled to be warmer; when the color tone of the user interface is relatively warm, the color temperature of the screen is correspondently increased, so that the color is cooled, the final display effect of the user interface is more natural and more real by virtue of mutual integration and mutual counteraction, the distortion of the picture color is avoided, the display effect of the terminal is improved, and the user experience is enhanced.
Description
technical field [0001] The invention relates to the technical field of communication, in particular to a method and a device for adjusting the color temperature of a screen. Background technique [0002] The color temperature of the screen is one of the most important criteria to measure the quality of the screen color display. The user's perception of the same color on the screen varies with the color temperature of the screen. Therefore, terminal equipment usually allows users to manually adjust the color temperature of the screen, but as the terminal With the development of intelligent technology, manual adjustment of the screen color temperature is obviously unable to meet the needs of users. [0003] At the same time, different user interfaces of terminals have different color tones displayed on the screen, some are colder and some are warmer. When the color temperature of the screen does not match the color tone of the user interface, the color of the screen will be di...
