Default separate threshold value.
For example, terminal continues to determine whether obstacle far from screen when terminal determines no obstacle close to terminal.By
In obstacle far from when, the light of transmitter transmitting does not have a blocking of obstacle, thus receiver can only receive it is seldom
Light namely light intensity value are less than default far from threshold value.If it is default far from threshold value that terminal determines that the average value is less than, terminal is executed
S1034, if terminal determines that the average value is more than or equal to the default separate threshold value, terminal can be with return step S1033.
S1034, if it is determined that the average value to be less than this default far from threshold value, it is determined that screen of the obstacle far from terminal.
