and if the duty ratio of the pixel points with the tone color being the main color in the real-time environment image outside the vehicle is larger than a preset proportion threshold value, controlling the lighting device according to the overall brightness and the main color.
Specifically, after determining the main color of the real-time environment image outside the vehicle, judging whether the duty ratio of the pixel points with the hue color being the main color in the real-time environment image outside the vehicle is greater than a preset proportion threshold (30% in the embodiment), if so, controlling the lighting device according to the main color and the overall brightness, and adjusting the display color and the display brightness of the lighting device, if not, considering that the duty ratio of the main color is too low, at the moment, not adjusting the lighting device, and keeping the display color and the display brightness of the lighting device unchanged.
