1. A parameter adjustment method, applied to an electronic device, the electronic device comprising a front camera and a display screen, and the parameter adjustment method comprising:
obtaining, when the display screen displays data, a first image captured by the front camera that runs based on an initial exposure parameter in response to a first instruction, the initial exposure parameter matching an ambient light brightness;
calculating an image brightness of the first image by using image data of the first image;
adjusting the initial exposure parameter of the front camera based on a difference between the image brightness of the first image and a standard brightness, to obtain an exposure parameter adjustment value, the exposure parameter adjustment value being used by the front camera to run based on the exposure parameter adjustment value in response to a second instruction, to capture another image;
configuring a confidence level for the first image according to a comparison result of the image data of the first image with a sample feature library, the confidence level representing a probability that the first image comprises an image of human eyes gazing at the display screen; and
controlling, when the confidence level of the first image is not less than a preset threshold, the display screen not to be turned off, the preset threshold matching the ambient light brightness.
