Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearly, hereinafter with reference to the accompanying drawing in the embodiment of the present invention, technical scheme is described clearly and completely by embodiment, it is clear that, described embodiment is a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
Embodiment one
Fig. 1 is the schematic flow sheet of a kind of method identifying self-shooting bar that the embodiment of the present invention one provides.The method is applicable to user and uses self-shooting bar to carry out situation about taking pictures, and can be performed by the device identifying self-shooting bar being configured in mobile terminal, and described device can be realized by software and/or hardware.Referring to Fig. 1, the method identifying self-shooting bar that the present embodiment provides specifically includes:
S110, when the earphone interface of mobile terminal have external equipment headset plug insert time, simultaneously start earphone MIC and main MIC recording；
Wherein, described headset plug is preferably four-section type headset plug.
Headset plug mainly has syllogic and a four-part form two types, line traffic control self-shooting bar and on four-section type headset equipment general configuration be four-section type headset plug.In program of mobile terminal running, mobile terminal first detects whether that the headset plug of external equipment inserts earphone interface；If so, judge whether described headset plug is four-section type headset plug.Specifically, when the headset plug that the earphone interface of mobile terminal has external equipment inserts, mobile terminal producing headset plug and insert interruption, then, the headset plug that mobile terminal continues to judge to insert is syllogic or four-part form.Wherein it is possible to judge whether headset plug is four-section type headset plug in the following manner:
Detect the MIC end of described headset plug and the resistance of ground end whether in preset range；If, it is determined that described headset plug is four-section type headset plug.
If headset plug is syllogic, then only the end of this headset plug, be considered as the MIC end on headset plug and ground terminal shortcircuit, hold with collectively constituting, then the MIC end of three-section earphone is zero with the resistance of ground end.And have certain resistance between MIC end and low side for four-section type headset equipment, and this resistance is within certain scope.Therefore can by whether the resistance of the MIC end of test earphone plug with ground end determines in preset range that the headset plug inserting mobile terminal is four-section type headset plug or three-section earphone plug.
Determining that the headset plug inserting mobile terminal earphone socket is when being four-section type headset plug, L channel end on mobile terminal earphone socket, R channel end, MIC end and ground end connect one to one with the L channel end on four-section type headset plug, R channel end, MIC end and ground end.Now, earphone MIC and main MIC can be started to record simultaneously.Specifically, terminal inner generally has two recording channels, it is possible to use a recording channel carries out earphone MIC recording, and another recording channel carries out MIC recording.Wherein, main MIC recording is for adopting intrinsic MIC on mobile terminal to record, for instance when voice call, and by the main MIC typing call sound of terminal, earphone MIC recording is adopt the earphone MIC being connected with mobile terminal by headset plug to record.Can not be oversize it addition, open earphone MIC and the main MIC time recorded.The identification of self-shooting bar is a shorter process, if record length is oversize, identification process can be caused oversize.For example, it is possible to open the external voice signal of recording typing 500ms.
It should be noted that, owing to the headset plug of prior art main flow is four-section type headset plug, headset plug in the present embodiment is preferably four-section type headset plug, as long as the headset plug with MIC can be used on self-shooting bar in the present embodiment, such as, the headset plug in the present embodiment can include the headset plugs such as the five-part form with MIC.
S120, frequency and/or energy according to the first audio signal of described earphone MIC typing and the second audio signal of described main MIC typing determine whether described external equipment is self-shooting bar.
When the external equipment connecting mobile terminal is self-shooting bar, owing to self-shooting bar MIC circuit not realizing the MIC of recording, after starting earphone MIC recording, typing is less than acoustical signal, and namely the frequency of the signal of typing or energy will be very low, equal to zero or close to zero.And when the external equipment connecting mobile terminal is ear speaker device, starting the acoustical signal of typing after earphone MIC records is the acoustical signal near ear speaker device, the frequency of the audio signal of typing or energy are generally of a relatively high.Therefore, it can the frequency of the second audio signal of the first audio signal according to earphone MIC typing and main MIC typing and/or energy determines whether the external equipment connecting mobile terminal is self-shooting bar.
Specifically, can determine whether the equipment connecting mobile terminal is self-shooting bar by following method: if the frequency of described first audio signal and energy are respectively smaller than the first setting threshold value and second and set threshold value, and the frequency of described second audio signal sets the energy of threshold value or described second audio signal and sets threshold value more than the 4th more than the 3rd, it is determined that described external equipment is self-shooting bar.
When the frequency of the first audio signal and energy are respectively smaller than the first setting threshold value and second sets threshold value, illustrate by earphone MIC typing less than corresponding audio signal, can determine that the external equipment connecting mobile terminal is self-shooting bar or the ear speaker device for being under the quiet environment of comparison, on this basis, if the frequency of the second audio signal sets the energy of threshold value or the second audio signal and sets threshold value more than the 4th more than the 3rd, can accurately judge that the external equipment connecting mobile terminal is as self-shooting bar.
It should be noted that, in a quiet environment, even if the external equipment being connected mobile terminal by four-section type headset plug is ear speaker device, it is relatively low by the frequency of the first audio signal of earphone MIC typing and energy, also relatively low by the frequency of the second audio signal of main MIC typing or energy, now mobile terminal can be identified as ear speaker device by unified for the external equipment being connected mobile terminal by headset plug.
Above-mentioned each sets threshold value and can be configured according to the system of different mobile terminals and self-shooting bar.
The technical scheme that the present embodiment provides, detect when the earphone interface of mobile terminal have external equipment headset plug insert time, start earphone MIC and main MIC recording simultaneously, and analyze frequency and the energy of main MIC and earphone MIC recording data, frequency and energy according to main MIC and earphone MIC recording data determine whether external equipment is self-shooting bar, it is possible to automatically identify self-shooting bar.
