Embodiment
To make the object, technical solutions and advantages of the present invention clearer, hereinafter with reference to attached in the embodiment of the present invention
Figure, technical scheme is clearly and completely described by embodiment, it is clear that described embodiment is the present invention one
Section Example, rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art are not doing
Go out under the premise of creative work the every other embodiment obtained, belong to the scope of protection of the invention.
Embodiment one
Fig. 1 is a kind of schematic flow sheet of the method for identification self-shooting bar that the embodiment of the present invention one provides.This method is applicable
In the situation that user is taken pictures using self-shooting bar, can be performed by the device for the identification self-shooting bar being configured in mobile terminal,
Described device can be realized by software and/or hardware.Referring to Fig. 1, the method for the identification self-shooting bar that the present embodiment provides specifically includes：
S110, when the earphone interface of mobile terminal have external equipment headset plug insert when, while start earphone MIC and
Main MIC recording；
Wherein, the headset plug is preferably four-section type headset plug.
Headset plug mainly has a three-stage and four-part form two types, general on line traffic control self-shooting bar and four-section type headset equipment
Configuration is four-section type headset plug.In program of mobile terminal running, mobile terminal has first detected whether that outside is set
Standby headset plug insertion earphone interface；If so, judging whether the headset plug is four-section type headset plug.Specifically, when
When the headset plug that the earphone interface of mobile terminal has external equipment inserts, it can be produced on mobile terminal in headset plug insertion
Disconnected, then, mobile terminal continues to judge that the headset plug of insertion is three-stage or four-part form.Wherein it is possible to by with lower section
Formula judges whether headset plug is four-section type headset plug：
Detect the headset plug MIC ends and ground terminal resistance whether within a preset range；If, it is determined that institute
It is four-section type headset plug to state headset plug.
If headset plug is three-stage, the only ground terminal of the headset plug, be considered as MIC ends on headset plug with
Ground terminal shortcircuit, ground terminal is collectively constituted, then the MIC ends of three-section earphone and the resistance of ground terminal are zero.And set for four-section type headset
There is certain resistance for standby between MIC ends and low side, and the resistance is within the scope of certain.Therefore detection can be passed through
Whether the MIC ends of headset plug and the resistance of ground terminal determine that the headset plug for inserting mobile terminal is within a preset range
Four-section type headset plug or three-section earphone plug.
It is determined that when the headset plug of insertion mobile terminal earphone socket is four-section type headset plug, mobile terminal earphone socket
On L channel end, R channel end, MIC ends and ground terminal and four-section type headset plug on L channel end, R channel end, MIC
End and ground terminal connect one to one.Now, earphone MIC can be started simultaneously and main MIC is recorded.Specifically, terminal inner
Typically there are two recording channels, a recording channel can be used to carry out earphone MIC recording, another recording channel carries out MIC
Recording.Wherein, main MIC recording are to be recorded using MIC intrinsic on mobile terminal, such as in voice call, pass through end
Main MIC typings call sound is held, earphone MIC recording are to be carried out using the earphone MIC being connected by headset plug with mobile terminal
Recording.In addition, the time for opening earphone MIC and main MIC recording can not be oversize.The identification of self-shooting bar is a shorter process,
If record length is oversize, identification process can be caused oversize.For example, recording typing 500ms external voice signal can be opened.
It should be noted that because the headset plug of prior art main flow is four-section type headset plug, in the present embodiment
Headset plug is preferably four-section type headset plug, as long as the self-timer that the headset plug with MIC can be in the present embodiment
Used on bar, for example, the headset plug in the present embodiment may include the headset plugs such as the five-part form with MIC.
S120, according to the first audio signal of the earphone MIC typings and the second audio signal of the main MIC typings
Frequency and/or energy determine whether the external equipment is self-shooting bar.
When the external equipment for connecting mobile terminal is self-shooting bar, due to recording is not realized on self-shooting bar MIC circuits
MIC, start after earphone MIC recording typing less than voice signal, i.e. the frequency of the signal of typing or energy will be very low, etc.
In zero or close to zero.And when the external equipment for connecting mobile terminal is ear speaker device, start typing after earphone MIC recording
Voice signal be voice signal near ear speaker device, the frequency or energy of the audio signal of typing are typically of a relatively high.
Therefore, can according to the frequency of the first audio signal of earphone MIC typings and the second audio signal of main MIC typings and/or
Energy determines whether the external equipment of connection mobile terminal is self-shooting bar.
Specifically, whether the equipment that connection mobile terminal can be determined by following methods is self-shooting bar：If first sound
The frequency and energy of frequency signal are respectively smaller than the first given threshold and the second given threshold, and the frequency of second audio signal
Rate is more than the 3rd given threshold or the energy of second audio signal is more than the 4th given threshold, it is determined that the outside is set
Standby is self-shooting bar.
When the frequency and energy of the first audio signal are respectively smaller than the first given threshold and the second given threshold, illustrate logical
Earphone MIC typings are crossed less than corresponding audio signal, it may be determined that the external equipment for connecting mobile terminal is self-shooting bar or is place
Ear speaker device under quieter environment, on this basis, if the frequency of the second audio signal is more than the 3rd given threshold
Or second the energy of audio signal be more than the 4th given threshold, the external equipment that can accurately judge to connect mobile terminal is self-timer
Bar.
It should be noted that in a quiet environment, even if connecting mobile terminal by four-section type headset plug
External equipment is ear speaker device, is relatively low by the frequency and energy of the first audio signal of earphone MIC typings, passes through master
The frequency or energy of second audio signal of MIC typings are also than relatively low, and now mobile terminal will can be connected by headset plug
The external equipment for connecing mobile terminal is uniformly identified as ear speaker device.
Above-mentioned each given threshold can be configured according to the system of different mobile terminal and self-shooting bar.
The technical scheme that the present embodiment provides, inserted in the earphone that the earphone interface detected when mobile terminal has external equipment
During head insertion, while start earphone MIC and main MIC recording, and analyze the frequency and energy of main MIC and earphone MIC recording datas,
Determine whether external equipment is self-shooting bar according to the frequency and energy of main MIC and earphone MIC recording datas, can automatically identify
Self-shooting bar.
