1. An image adjustment method, comprising:
acquiring a maximum current setting value and an expected current value corresponding to a backlight;
determining an operating current value corresponding to the backlight according to the maximum current setting value and the expected current value;
determining a target brightness array of the backlight according to the operating current value, a maximum overdrive current setting value corresponding to the backlight, and a current brightness array of the backlight corresponding to a current displayed image on a screen, wherein the target brightness array comprises a plurality of target brightness data; and
controlling a brightness of the backlight according to the plurality of target brightness data in the target brightness array to adjust an image displayed on the screen;
wherein determining an operating current value corresponding to the backlight according to the maximum current setting value and the expected current value comprises:
if the expected current value is less than or equal to the maximum current setting value, determining the expected current value as the operating current value corresponding to the backlight;
if the expected current value is greater than a maximum current value corresponding to the backlight, acquiring an overdrive time during which a current value corresponding to the backlight is continuously greater than the maximum current setting value; and
determining the operating current value corresponding to the backlight according to the overdrive time;
wherein determining the operating current value corresponding to the backlight according to the overdrive time comprises:
if the overdrive time is equal to a first preset time threshold, determining the maximum current setting value as the operating current value of the backlight;
if the overdrive time is greater than the first preset time threshold, acquiring a second preset time threshold, wherein the second preset time threshold is greater than the first preset time threshold;
determining the operating current value corresponding to the backlight according to the second preset time threshold;
if the overdrive time is less than the first preset time threshold, acquiring a number of times overdrive during which the current value corresponding to the backlight is greater than the maximum current setting value within a preset time period; and
determining the operating current value corresponding to the backlight according to the number of times overdrive.
