Abstract: A display adjustment method and apparatus, a system, and a storage medium. The method includes: obtaining a reference position from an image displayed by a head-up display HUD system, where the reference position is related to a focal position, on the image displayed by the HUD system, of an eye of a user; obtaining a brightness weakening coefficient of each pixel based on a distance between each pixel in the image and the reference position; adjusting display brightness of each pixel in the image based on the brightness weakening coefficient of each pixel; and displaying an adjusted image based on the display brightness of each pixel in the adjusted image.

Abstract: Example electric appliance identification methods and apparatuses are provided. One example method includes obtaining, by a power line communication (PLC) device, a first noise signal in a circuit. The PLC device can then obtain first data based on the first noise signal, where the first data is used to describe a time-frequency feature of the first noise signal. The PLC device can then obtain, based on an electric appliance identification model and the first data, an electric appliance identification result corresponding to the first noise signal, where the electric appliance identification model is obtained based on a signal including a second noise signal of at least one known electric appliance.
