Specifically, in this embodiment, the color-taking illumination control method further includes: and enhancing the RGB values by adopting an enhancement algorithm, and sending the enhanced RGB values to the background lamp so as to control the color of the background lamp. Since the screen color collected by the camera is diluted due to illumination factors or specular reflection in the user's home, an enhancement algorithm (which may also be referred to as a color exaggeration algorithm) is required to enhance the vividness of the color (for example, the exaggeration algorithm is that r=r=160%, g=g=160%, and b=b×160%). With the popularity of OLED televisions, the problem of specular reflection becomes smaller because each pixel is self-luminous. For televisions or displays of other panels, the original color is restored by adopting a color enhancement technology, and meanwhile, the problems of warm color temperature at the near end and cold temperature at the far end are solved by calibrating the color temperature. The RGB value is enhanced by the enhancement algorithm, so that the brightness of the background light is improved, the condition that the color of a screen collected by a camera is light due to factors such as illumination factors or specular reflection is reduced, the color and the brightness of the background light correspond to the color and the brightness of a display screen to a high degree, and the effectiveness of the color taking illumination control method is effectively improved.
In this embodiment, the RGB value is enhanced by the enhancement algorithm, so as to improve the brightness of the backlight, reduce the occurrence of the situation that the color of the screen collected by the camera is light due to factors such as illumination factors or specular reflection, so that the color and brightness of the backlight correspond to the color and brightness of the display screen to a high degree, and effectively improve the effectiveness of the color-taking illumination control method.
