S103, the average value and predetermined threshold value is compared, obtains comparative result.

For example, average value is compared by terminal with predetermined threshold value, to judge obstacle close to or away from terminal.This is pre- If threshold value can include presetting close to threshold value and default remote threshold value, this is default default away from threshold value more than this close to threshold value.Its Middle step S103 can include：

S1031, to judge whether the average value is more than default close to threshold value.

For example, whether terminal judges have screen of the obstacle close to terminal.Due to have obstacle close to when, transmitter hair The light penetrated is blocked thing and is reflected back in cover plate, thus the light intensity value that receives of receiver be more than it is default close to threshold value.Namely the It is default close to threshold value that the average value for the light intensity value that one receiver or the second receiver are received is more than this.If terminal judges that this is put down Average is more than default close to threshold value, then terminal performs S1032.If it is default close that terminal judges that the average value is less than or equal to this Threshold value, then terminal can perform step S1033.

S1032, if it is determined that the average value to be more than this default close to threshold value, it is determined that screen of the obstacle close to terminal.

S1033, if it is determined that the average value is less than or equal to, this is default close to threshold value, then judges whether the average value is less than Default remote threshold value.

For example, when terminal judges no obstacle close to terminal, terminal continues to determine whether obstacle away from screen.By In obstacle away from when, the light of transmitter transmitting does not have the stop of obstacle so that reflection light is reduced, therefore receiver Seldom light can only be received, namely light intensity value is less than default remote threshold value.If it is default remote that terminal judges that the average value is less than From threshold value, then terminal performs S1034, if terminal judges the average value and is more than or equal to that this is default away from threshold value, terminal can With return to step S1033.

S1034, if it is determined that the average value to be less than this default away from threshold value, it is determined that screen of the obstacle away from terminal.

S104, according to the comparative result screen intensity of terminal is controlled.

For example, comparative result of the terminal according to step S103, the brightness to screen is controlled.The control is such as extinguishing Or lighting operation.Specifically, step S104 can include：

S1041, when terminal is determined with obstacle close to the screen of terminal, terminal extinguish screen.

For example, when terminal is determined with obstacle close to terminal, terminal extinguishes screen, that is, the now brightness value of screen It is minimum.

S1042, when terminal judges screen of the obstacle away from terminal, then light screen.

For example, when terminal is determined with obstacle away from screen, end point bright screen curtain, namely terminal is by the brightness value of screen Default display brightness is adjusted to by minimum.

Due to the existing detection method for detecting whether obstacle close to screen, mainly entered by the data of single receiver Row judges, therefore easily the situation of erroneous judgement occurs.

Although the above method is by taking optical signal as an example, the present invention can not be constituted and limited.The method of the present embodiment is same Sample is applied to other kinds of signal.

The method of adjustment of the screen intensity of the present embodiment, due to the first detected value and the by obtaining the first receiver Second detected value of two receivers；Calculate the average value of first detected value and second detected value；By the average value and default Threshold value is compared, and obtains comparative result；The screen intensity of terminal is controlled according to the comparative result.Due to passing through two The average value of the light intensity value of receiver is compared with default close to threshold value with default remote threshold value respectively, improves the standard of judgement True property.
