    • Abstract:
      Information processing methods and electronic devices are provided. A method for an electronic device with a display unit may comprise: determining a first environmental light parameter under an environment where the electronic device is disposed; and determining a first display parameter for output by the display unit based on the first environmental light parameter. When the display unit performs display based on the first display parameter, a difference between a first color temperature of the display unit and a second color temperature of the environment may be less than a first preset threshold.
