for example, the infrared light intensity of the environment around the mobile phone is measured by an environment infrared light intensity sensor of the mobile phone, where the infrared light intensity may be the environment infrared light intensity measured in the current measurement period, or may be an average value of the environment infrared light intensities measured in multiple measurement periods.
S102, judging whether the ambient infrared light intensity meets a preset rule, if so, executing a step S103, and if not, returning to the step S101.
For example, the preset rule may be preset by a user, may be factory default settings of the mobile phone, or may be downloaded by the mobile phone from a network server or other terminals. And the mobile phone judges whether the ambient infrared light intensity accords with the preset rule.

For example, the mobile phone compares the measured ambient infrared light intensity with a preset ambient infrared light intensity value, and if the measured ambient infrared light intensity reaches the preset ambient infrared light intensity value, it may be determined that the ambient infrared light intensity meets a preset rule, and step S103 is executed.
