1. A backlight display control method, wherein-the-method comprising:
obtaining a fused image based on an input image;
identifying a salient region and a non-salient region in the fused image;
increasing a backlight power value of the salient region; and/or
decreasing a backlight power value of the non-salient region,
wherein the obtaining a fused image based on an input image comprises;
detecting the input image according to a saliency detection algorithm to obtain a first detection result;
detecting the input image according to an artificial intelligence (AD information identification algorithm to obtain a second detection result; and
obtaining the fused image based on the first detection result and the second detection result, and
wherein the obtaining the fused image based on the first detection result and the second detection result comprises:
determining a first weight value of a high luminance pixel in the first detection result;
determining a second weight value of a high luminance pixel in the second detection result, and
adjusting a weight value of a high luminance pixel based on the first weight value and the second weight value, to obtain the fused image.
