Referring to fig. 1b, fig. 1b is a first flowchart illustrating an ambient light detection method according to an embodiment of the present disclosure. The ambient light detection method includes:
The ambient light detection instruction is used for instructing the ambient light sensor to detect the light intensity of the ambient light. The detection frequency of the ambient light sensor may be determined in advance, for example, the ambient light intensity of the environment in which the mobile terminal is located is detected once at intervals of 5 s. Or when the display screen is switched from the screen-off state to the screen-on state, the ambient light is triggered to be acquired, and the specific trigger condition can be set arbitrarily, which is not limited here.
Specifically, the working state of the display screen, that is, the state of the display screen when being displayed, that is, the bright screen state, may be a mode of determining whether the display screen is in the working state, that is, a mode of detecting a parameter representing the state of the display screen. For example, if the parameter of the display screen in the operating state is set to 1 and the parameter in the non-operating state is set to 0, it can be determined whether the display screen is currently in the operating state by reading the parameter.
In addition, the manner of determining whether the display screen is in the working state may be to determine whether a touch operation of the user on the display screen is received or not or whether a physical key arranged on the mobile terminal housing is pressed within a period of time from the reception of the ambient light detection instruction, so as to determine whether the current state of the display screen is in the working state.
