The present invention provides a kind of method taken over seamlessly based on ray machine auto brightness, and this method uses data prediction：It picks
Except exceptional value and smoothing processing.
Optical sensor will sample a light sensation lux value per setting time (such as 200ms).
Rejecting abnormalities value：
It provides a confidence level, determines a cofidence limit, every error more than the limit, it is abnormal to be considered as it
Value, to be rejected.The value 0-65535 of light sensation Lux is normal value.
First sampled point P1 is saved in smoothing processing queue.
Next sampled point P2 and P1 errors will preserve P2 if it is less than difference threshold (20000)；
Error is more than 20000, temporarily judges that P2 is abnormal, needs to compare next sampled point P3, if P2 and P3 is missed
Difference is less than 20000, it is confirmed that P2 is normal sampled point, P2 is added to smoothing processing queue, if P2 and P3 errors are still
It more than 20000, decides that P2 is abnormal point, rejects this sampled point P2.P3 is continued and next sampled point compares, and so on
Detect exceptional value.
