Abstract
A backlight display control method and apparatus are provided. The method includes: 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. In this way, a region of interest that is for human eyes and that is in the image may be identified, the backlight power value and luminance distribution are controlled based on salience information, the backlight power value is dynamically allocated, and contrast of the region of interest for human eyes is maintained or improved, to improve quality of a displayed image under a same power value constraint; and backlight luminance is adjusted, without weakening image effect, to decrease or increase a backlight power value of a specific region, and thus improve contrast and lighting effect.
