if it is detected that the incident light of the light sensing fingerprint identification module 24 is blocked, the light sensing scanning identification module is instructed to scan and identify the information of the blocking object blocking the light sensing fingerprint identification module 24.
In this embodiment, when the light sensor detects that the light sensing fingerprint identification module 24 is blocked, the light sensing scanning identification module is notified to scan the blocking object of the light sensing fingerprint identification module 24 to obtain the blocking object information of the blocking object, and then the light sensing scanning identification module identifies the blocking object information. In one embodiment, the hollow areas are uniformly arranged on the light sensing scanning identification module.

In this embodiment, when the light sensor detects that the light-sensitive fingerprint identification module 24 is blocked by the blocking object, the light sensor notifies the timer to start timing, and it is assumed that the time point at which the timer starts timing is the first time point; when the light sensor detects that the light-sensitive fingerprint identification module 24 is not shielded by the shielding object any more, the timer is informed to stop timing, and the time point when the timer stops timing is assumed to be a second time point; the duration between the second time point and the first time point is the continuous duration of the incident light of the light sensing fingerprint identification module 24 being blocked. When the CPU determines that the continuous time length during which the incident light of the light sensing fingerprint identification module 24 is blocked is greater than or equal to the preset time length threshold, it indicates that the probability that the light sensing fingerprint identification module 24 is blocked by mistake is low, and at this time, the blocking object is scanned again, so that the probability of misidentification can be reduced.

In this embodiment, a capacitance module is added to the light sensing fingerprint identification module 24, so that when a user presses the light sensing fingerprint identification module 24, a capacitance value of the capacitance module of the light sensing fingerprint identification module 24 changes, and the CPU selects whether to notify the light sensing fingerprint identification module to scan the shielding object according to the change of the capacitance value of the capacitance module, for example, if the capacitance value is smaller than a preset capacitance threshold value, the CPU does not instruct the light sensing fingerprint identification module to scan the shielding object, so that the probability that the light sensing fingerprint identification module 24 is also started when the non-finger shields the light sensing fingerprint identification module 24 can be further reduced.
Optionally, the mobile terminal includes a central processing unit CPU, and before the instructing the light sensing scanning and recognizing module to scan and recognize the shelter information sheltering the light sensing fingerprint recognizing module 24, the mobile terminal includes:

Optionally, after the light-sensitive scan identification module is instructed to scan and identify the obstruction information that obstructs the light-sensitive fingerprint identification module 24,

the light sensation scanning and identifying module sends an identification result for identifying the information of the sheltering object sheltered from the light sensation fingerprint identifying module 24 to the CPU;
and if the identification result indicates that the shelter information is different from the pre-stored fingerprint information, the CPU indicates the loudspeaker to send out a re-identification prompt.
In this embodiment, if it is determined that the obstruction information is different from the pre-stored fingerprint information, a re-identification prompt is sent through the loudspeaker, so that the user can re-identify the obstruction information. Optionally, the microphone counts the number of times of sending the re-identification prompt, and if the counted number of times is greater than or equal to a preset prompt number threshold, the microphone is not instructed to send the re-identification prompt after the identification result indicates that the obstruction information is different from the pre-stored fingerprint information again.

In order to avoid sending a re-identification prompt under all conditions that the identification result indicates that the obstruction information is different from the pre-stored fingerprint information, and further improve the effectiveness of sending the re-identification prompt, the second similarity threshold is set in the embodiment, and the second similarity threshold is smaller than the first similarity threshold.

the light sensation scanning identification module scans the information of a shelter sheltering the light sensation fingerprint identification module; comparing the shelter information with pre-stored fingerprint information, wherein the number of the pre-stored fingerprint information is more than or equal to 1;
if the similarity between the obstruction information and any pre-stored fingerprint information is larger than or equal to a first similarity threshold value, judging that the obstruction information is the same as the pre-stored fingerprint information, otherwise, judging that the obstruction information is different from the pre-stored fingerprint information.
6. The mobile terminal of claim 5, wherein the mobile terminal further comprises a microphone; correspondingly, after the indicating the light sensing scanning identification module scans and identifies the shelter information sheltering the light sensing fingerprint identification module, the method comprises the following steps:
the light sensation scanning and identifying module sends an identification result for identifying the information of the sheltering object sheltered from the light sensation fingerprint identifying module to the CPU;
and if the identification result indicates that the shelter information is different from the pre-stored fingerprint information, the CPU indicates the loudspeaker to send out a re-identification prompt.
7. The mobile terminal according to claim 6, wherein if the identification result indicates that the obstruction information is different from the pre-stored fingerprint information, the CPU instructs the microphone to issue a re-identification prompt, including:
if the identification result indicates that the obstruction information is different from the pre-stored fingerprint information, the CPU judges whether the similarity between the obstruction information and any one of the pre-stored fingerprint information is larger than or equal to a second similarity threshold, if so, the CPU indicates the loudspeaker to send out a re-identification prompt, and the second similarity threshold is smaller than the first similarity threshold.
8. The mobile terminal of claim 7, after the CPU instructs the microphone to issue a re-recognition cue, comprising:
the CPU counts the times of sending the re-identification prompt by the loudspeaker, judges whether the times of sending the re-identification prompt by the loudspeaker is larger than or equal to a preset time threshold value or not, and instructs the loudspeaker to send the prompt of cleaning the light sensation fingerprint identification module if the times of sending the re-identification prompt by the loudspeaker is larger than or equal to the preset time threshold value.
