AMBIENT LIGHT DETECTION METHOD AND APPARATUS, AND STORAGE MEDIUM

An ambient light detection method includes: in response to monitoring that a current backlight level of a display screen exceeds a preset backlight level threshold, acquiring an image grayscale value sent by a driving portion in the display screen; compensating a first gray level value collected by a light sensor by using the image grayscale value to obtain a current gray level value, the current gray level value being configured to represent a gray level corresponding to current external ambient light detected by the light sensor; and acquiring illumination intensity of the current external ambient light based on the current gray level value, the illumination intensity being used as a basis for adjusting backlight brightness of the display screen.
