6. optical ftngetpnnt acquisidon method as described in claim 1, which is characterized in that described " to be adopted carrying out optical finger print to fingerprint
When collection, the signal input pin TS IN states in detection fingerprint control IC " before, further include：
Obtain the current finger print area contact area of fingerprint collecting；
If current finger print area contact area reaches the preset ratio of preset area, the TS IN states are low, and are started
Optical ftngetpnnt acquisidon is carried out to the fingerprint；
If current finger print area contact area is not up to the preset ratio of the preset area, the TS IN states
For height, stop carrying out optical ftngetpnnt acquisidon to the fingerprint, and " the current finger print area contact surface of fingerprint collecting is obtained described in return
Product ".
7. optical ftngetpnnt acquisidon method as described in claim 1, which is characterized in that described " to be adopted carrying out optical finger print to fingerprint
When collection, the signal input pin TS IN states in detection fingerprint control IC " before, further include：
Obtain the current finger print area pressure of fingerprint collecting；
If the current finger print pressure reaches preset pressure value, the TS IN states are low, and start to carry out the fingerprint
Optical ftngetpnnt acquisidon；
If the current finger print pressure is not up to the preset pressure value, the TS IN states are height, are stopped to the fingerprint
Carry out optical ftngetpnnt acquisidon, and " the current finger print area pressure for obtaining fingerprint collecting " described in return.
8. a kind of optical fingerprint acquisition apparatus, which is characterized in that including：Detection module and closedown module；
The detection module, for when carrying out optical ftngetpnnt acquisidon to fingerprint, detection fingerprint to control the signal input pin in IC
TS IN states；The TS IN states include high and low；
The closedown module, if being height for the TS IN states, controlling IC by the fingerprint receives interrupt signal, closes
The interruption detection is closed, and stops carrying out optical ftngetpnnt acquisidon to the fingerprint.
9. a kind of user terminal, which is characterized in that including memory and processor, the memory is for storing optical finger print
Capture program, the processor runs the optical ftngetpnnt acquisidon program so that the user terminal executes such as claim 1-7
Any one of the optical ftngetpnnt acquisidon method.
10. a kind of computer readable storage medium, which is characterized in that be stored with optics on the computer readable storage medium and refer to
Line capture program realizes the light as described in any one of claim 1-7 when the optical ftngetpnnt acquisidon program is executed by processor
Learn fingerprint collecting method.
