Angle value, then confirm that this mobile terminal is in strong light environment；
Being built-in with ambient light sensor in the terminal, whether mobile terminal is in strong light environment, can be by this environment
Sensor judges, such as this light intensity value preset is 8000 luxs, when the current light that ambient light sensor gets
Intensity level has exceeded 8000 luxs, then assert that this mobile terminal is currently in strong light environment, and now, proximity transducer may
Caused the numerical exception of collection by the interference of high light, and and then draw abnormal reported event, reporting close to event of mistake
Or away from event.
Wherein, refer to that face or human ear and the distance of mobile terminal screen, less than preset distance, confirm people close to event

From event, specific implementation can be to be the following two kinds mode:
First kind of way: adjust current away from threshold values according to sensor correction value；
By this sensor correction value and this preset being added away from threshold values, obtain this currently away from threshold values so that when this
When two distance values are more than this currently away from threshold values, proximity transducer reports away from event.That is, improve away from threshold values, so, adopt
Collect to distance value can be only achieved more greatly and report the condition away from event.
The second way: adjust second distance value according to sensor correction value.
Obtain the difference between this sensor correction value and this second distance value so that when this difference more than this currently away from
During threshold values, proximity transducer reports away from event.That is, this second distance value, equally, distance value to be collected more great talent are reduced
