It should be noted that mobile phone is only a kind of citing of electronic device 300, the utility model is simultaneously not particularly limited, this
Utility model can be applied to the electronic devices such as mobile phone, tablet computer 300, and the utility model does not limit this.
The method that iris recognition component wakes up mobile phone is described by taking mobile phone as an example below：
Mobile phone is static, and 132 lamp sleep state of iris camera 120, the first infrared lamp 131 and the second infrared lamp does not work,
Gravity sensor (gsensor) works, and power consumption is very low；
The state of monitoring mobile phone in real time；
Model is lifted, mobile phone z directions upwardly-directed generate acceleration, and acceleration value is more than threshold value, sets acceleration rate threshold,
Such as 2；
Meanwhile can mobile phone rotation angle be monitored by gyroscope, rotation angle threshold value, such as 30 degree are set.
If both it is more than simultaneously threshold value, it is believed that mobile phone is lifted at this time, and is screen towards user's face.
step1：The action that mobile phone lifts is detected by gravity sensor gsensor and gyro data；
step2：Simultaneously by proximity sensor, if detecting that mobile phone does not have object to block；
step3：Iris camera 120, infrared lamp 130 are automatically begun at once, proceeds by iris recognition.
In this way, user, during lifting, iris camera 120 and infrared lamp 130 have been switched on work, at this moment
Wait, user do not need to hand press power keys come bright screen identify again.
