S12：Realtime graphic is obtained by front camera.
After opening front camera in above-mentioned steps S11, realtime graphic can be obtained by front camera.It is specific next
Say, when user opens front camera and enters the preview interface taken pictures, front camera can obtain realtime graphic and pre-
Looking at interface is shown, in general, now user can lift mobile terminal and constantly adjust arm position it is preposition to adjust
Realtime graphic acquired in camera so that the position of user's facial image is user's included in the realtime graphic got
In expected range, therefore in the present embodiment, the realtime graphic for including user's facial image is obtained by front camera.At this
The realtime graphic got in step S12 is used for the face information for obtaining user from realtime graphic in following step S13.
S13：The face information of user is obtained from realtime graphic, distance threshold of taking pictures is set according to face information.
In this step S13, the face information of user is obtained in the realtime graphic obtained from above-mentioned steps S12, according to
Face information sets distance threshold of taking pictures.
The facial feature information of face information, i.e. people, facial feature information can include shape of face feature, human face five-sense-organ it is several
What shape and relative position relation between them, the physiological characteristic of face can also be included, so as to obtain age, property
Not, the relevant information such as race.
The user Position Approximate that arm is placed when being taken pictures using mobile terminal can be drawn by face information,
So as to generate distance value of the user corresponding to face information in the posture of different hand-held mobile terminals, according to the distance of acquisition
Value setting is taken pictures distance threshold.Wherein, distance threshold of taking pictures is an estimated mean value, is e.g. analyzed from big data data
The numerical value got, in general, threshold value of taking pictures can be distance value of the front camera apart from face certain point, for example, nose,
The distance value of mouth, eyes centre position etc. or front camera apart from face center.Wherein, according to user
The difference of the posture of hand-held mobile terminal, the distance range that will can take pictures are divided into distal and proximal two kinds, can also be divided into it is remote, in, it is near
Three kinds of distance ranges.
The distance threshold of taking pictures set in this step S13 according to face information is used in following step S15 with
The actual range obtained in step S14 is stated to be compared.
S14：Realtime graphic is analyzed to obtain front camera to the actual range of user's face.
In this step in S14, realtime graphic is analyzed, so as to obtain front camera to user's face information
Actual range.Specifically, generally mobile terminal is internally provided with depth of field sensing module, more can accurately measure
Front camera is different from above-mentioned steps S13 and set according to face information to the actual range of user's face in realtime graphic
Take pictures distance threshold, be the actual range for obtaining front camera apart from face in this step S14, before the actual range can be
Distance range value of the camera apart from face certain point is put, for example, nose, mouth, eyes centre position etc. or preceding

The actual range of front camera to user's face obtained in S14 is compared.
Specifically, distance range will be taken pictures compared with actual range, to show which scope active user belongs to
In value, when the difference of the posture according to hand-held mobile terminal, when the distance range that will take pictures is divided into distal and proximal two kinds, take pictures apart from threshold
Value then can as the line of demarcation of take pictures at a distance scope and scope of closely taking pictures, i.e., when actual range be less than or equal to take pictures away from
During from threshold value, then it is judged as scope of closely taking pictures, now performs following step S16, is taken pictures when actual range is more than apart from threshold
During value, then it is judged as scope of taking pictures at a distance, now performs following step S17；When be divided into it is remote, in, nearly three kinds of distance ranges when,
It can then regard middle distance as equal to distance threshold of taking pictures to take pictures scope, can then regard remote model of taking pictures as more than distance threshold of taking pictures
Enclose, less than taking pictures, distance threshold can then regard scope of closely taking pictures as, i.e., when actual range is less than or equal to distance threshold of taking pictures
When, then it is judged as closely taking pictures scope or middle distance is taken pictures scope, following step S16 is now performed, when actual range is more than
Take pictures distance threshold when, then be judged as scope of taking pictures at a distance, now perform following step S17.
S16：If actual range is less than or equal to distance threshold of taking pictures, enter triggering pattern of taking pictures manually.
By actual range and taken pictures in above-mentioned steps S15 after distance threshold is compared, when comparative result for it is actual away from
From less than or equal to take pictures distance threshold when, then enter and take pictures triggering pattern manually.
Specifically, user takes pictures when carrying out self-timer using mobile terminal when judging that actual range is less than or equal to
During distance threshold, camera applications are set as triggering pattern of taking pictures manually, i.e., by pressing secondary or physical bond or clicking on relevant range
Virtual key triggering take pictures to obtain desired image, wherein, secondary or physical bond can be volume key on mobile terminal or other
Button.
S17：If actual range is more than distance threshold of taking pictures, pattern is triggered into automatic camera.
By actual range and taken pictures in above-mentioned steps S15 after distance threshold is compared, when comparative result for it is actual away from
From more than take pictures distance threshold when, then into automatic camera trigger pattern.
Specifically, user takes pictures apart from threshold when carrying out self-timer using mobile terminal when judging that actual range is more than
During value, camera applications are set as that automatic camera triggers pattern, i.e., need not be by pressing secondary or physical bond or clicking on relevant range
The triggering of virtual key can take pictures, wherein, the mode of automatic camera triggering can have a variety of, such as countdown, acoustic control etc.
Etc. mode, the time of countdown, the speech trigger keyword of acoustic control can preset or follow default setting, for example, falling to count
When 4 seconds, say " shooting " etc..
For example, when user carries out self-timer in the position that actual range is more than distance threshold of taking pictures, arm can be stretched over movement
Terminal can maintain a more unstable posture, i.e. hand apart from face remote position, now user's hand-held mobile terminal
The completely hanging posture of thing is held in portion, and hand is easily shaken, it is impossible to is easily pressed secondary or physical bond by finger or is clicked on phase
The action that the triggering of the virtual key on region is taken pictures is closed, in general, except non-user will just clap before being taken pictures using camera applications
Sound control triggering is arranged to according to triggering pattern to take pictures, otherwise camera applications are taken pictures under any circumstance is all defaulted as taking pictures manually
Triggering pattern, but in the present embodiment, then be when judge actual range be more than take pictures distance threshold when, camera applications setting
Pattern is triggered for automatic camera, it is not necessary to which user does the adjustment of any setting, i.e., when user determines it is expectation figure in preview screen
During picture, action of taking pictures can be triggered automatically by saying " shooting " two words, obtains desired image.
The present embodiment mobile terminal includes front camera, by opening front camera；Obtained again by front camera
Take realtime graphic；The face information of user is obtained from realtime graphic, distance threshold of taking pictures is set according to face information；Analysis is real
When image to obtain front camera to the actual range of user's face；Compare actual range and distance threshold of taking pictures；It is if actual
Distance is less than or equal to distance threshold of taking pictures, then enters triggering pattern of taking pictures manually；If actual range is more than distance threshold of taking pictures,
Then enter automatic camera triggering pattern, can be adjusted automatically by identifying the distance between face and mobile terminal front camera
Beat shines triggering pattern, facilitates user quickly to trigger shooting to obtain desired image.
Referring to Fig. 2, Fig. 2 is a kind of flow signal of another embodiment of triggering method of taking pictures of mobile terminal of the present invention
Figure.In the present embodiment, mobile terminal includes front camera, and the triggering method of taking pictures of mobile terminal can include following step
Suddenly：
S21：Open front camera.
In this step S21, the front camera of mobile terminal is first turned on, mobile terminal is then lifted and prepares to take pictures.
Embodiment is similar with the above method, does not repeat herein.
S22：Realtime graphic is obtained by front camera.
After opening front camera in above-mentioned steps S21, realtime graphic can be obtained by front camera.It is specific real
It is similar with the above method to apply mode, does not repeat herein.
S23：The face information of user is obtained from realtime graphic, distance threshold of taking pictures is set according to face information.
In this step S23, jitter value is obtained by the gyroscope built in mobile terminal first, then judges jitter value
Whether it is more than dithering threshold, if it is not, obtaining the face information of user in the realtime graphic then obtained from above-mentioned steps S22, knows
The biological characteristic of others' face acquisition of information user；The arm exhibition value of user is calculated according to biological characteristic；Set and clapped according to arm exhibition value
Photographic range threshold value, distance threshold of taking pictures is set according to face information so as to realize.
Acquisition for mobile terminal to realtime graphic be face information for obtaining user, therefore be image obtained by ensureing
Quality, first acquired realtime graphic is detected in the present embodiment so that mobile terminal is preferable in realtime graphic quality
In the case of just continue the processing of next step.
Detection mode has a variety of, ensures that realtime graphic reaches quality requirement, such as following two detection modes.
The first detection mode：Acquisition for mobile terminal jitter value, and judge whether jitter value is more than dithering threshold, if it is not,
Then realtime graphic is preserved under exposal model；If so, then do not preserve realtime graphic under exposal model.
The sensor that can measure mobile terminal direction, angle etc. can be provided with current many mobile terminals, for example, it is heavy
Power inductor, gyroscope, electronic compass etc., are illustrated by taking gyroscope as an example below.
User can constantly shift one's position when using acquisition for mobile terminal realtime graphic or angle is found a view, therefore,
Before user places mobile terminal under plateau, the action of mobile mobile terminal is had, wherein, plateau can be put
It is placed on fixed support, or holds stable state, in the present embodiment, due to is that user is carried out certainly by mobile terminal
Clap, therefore plateau refers to hold stable state.User during mobile mobile terminal, the direction of mobile terminal,
The data such as angle can all be in a kind of state of change, above-mentioned variable condition typically be represented with jitter value, when mobile terminal is trembled
When dynamic value is larger, the realtime graphic that the camera of mobile terminal is got is probably unsharp, thus can pass through it is mobile eventually
Internal gyroscope is held to obtain jitter value, so as to help mobile terminal to detect whether the face of the acquisition user from realtime graphic
Information, i.e., when jitter value is larger, during more than dithering threshold, then do not obtain；If jitter value is smaller, during less than or equal to dithering threshold,
The face information of user is then obtained from realtime graphic.
Gyroscope inside mobile terminal can detect the data such as the direction that mobile terminal is presently in and angle, so as to logical
Cross algorithm and be converted into jitter value, user first can preset to the dithering threshold of mobile terminal, can also use movement
The dithering threshold of terminal acquiescence, by the way that the size of dithering threshold of the real-time jitter value of mobile terminal with setting is judged,
If the real-time jitter value of mobile terminal is not more than dithering threshold, then it is assumed that now mobile terminal realtime graphic meets to require, that is, exists
The face information of user is obtained under exposal model in realtime graphic, if the real-time jitter value of mobile terminal is more than dithering threshold
When, then it is assumed that now mobile terminal realtime graphic is unsatisfactory for requiring, i.e., user is not obtained in realtime graphic under exposal model
Face information.
Second of detection mode, mobile terminal judge whether the quality of realtime graphic meets quality requirements.
This detection mode is directly to judge whether to preserve the realtime graphic according to the quality of realtime graphic.Realtime graphic
Quality requirements can be judged according to image definition, and image definition refers to the clear of each thin portion shadow line on image and its border
Clear degree, mobile terminal can then obtain the readability of image after realtime graphic is obtained by some algorithms, and algorithm can
To be some Image Definitions, such as the evaluation function based on frequency characteristic of field, the evaluation letter based on statistical nature
Evaluation function several, based on space domain characteristic etc., i.e., when the condition under function used in the readability of image meets,
The face information of user is then obtained from realtime graphic.
The facial feature information of face information, i.e. people, can include human face five-sense-organ geometry and they between
Relative position relation, shape of face feature, the physiological characteristic of face can also be included, so as to obtain the phases such as age, sex, race
Information is closed, in the present embodiment, two attributes of age and sex in the biological characteristic of face are got after identification face information
Value.
Specifically, the face information of user carries out being detection and identification in this step S23 to realtime graphic, so as to
Age and the gender data of user is calculated according to face information, the module also in mobile terminal with depth of field perceptional function, its
In, the depth of field (DOF) refers to that in camera lens or other imager forward positions the quilt that the imaging of picture rich in detail determined can be obtained
Take the photograph object longitudinal separation scope.In the present embodiment, depth of field sensing module enters the age and gender data of acquisition as parameter
Row processing, so as to estimate the arm exhibition value of user, detect that user is the male and the female of 25~30 years old of 25~30 years old for example, working as
Arm exhibition value during property is different, is greater than the arm exhibition value of women with male's arm exhibition value under age bracket in adult, because
, according to age of user and the difference of sex, the arm exhibition value that depth of field sensing module estimates is also what is differed for this.Existed according to user
When being taken pictures using mobile terminal, the distance of stretching hand with arm it is different thus produce different arm exhibition values, according to user's difference
The posture of hand-held mobile terminal when carrying out self-timer, obtain arm exhibition value to form shooting distance threshold value, wherein, arm exhibition value is preposition
The distance range value of camera and human eye, can be it is remote, in, nearly three kinds of distance range front cameras are apart from user's eyes center
Point distance range value or front camera respectively apart from user's right and left eyes distance range value average value, herein
Do not limit.Arm exhibition value can set different distance ranges of taking pictures according to the difference of the posture of user's hand-held mobile terminal, i.e.,
User shrinks arm completely, partly stretch one's arm and full extension arm be divided into it is near, in, remote three kinds of distance ranges, therefore can be with
A value is taken in the distance value of front camera and human eye as distance threshold of taking pictures, when user shrinks arm, half stretching, extension completely
Then it is judged to being less than or equal to distance threshold of taking pictures during arm, is then judged to being more than distance of taking pictures when user's full extension arm
Threshold value, wherein distance threshold of taking pictures can be estimate arm exhibition value greatest measure 50% ± 7% or 60% ± 6%, tool
Body sets the mode for distance threshold of taking pictures not limit herein.
The distance threshold of taking pictures set in this step S23 according to face information is used in following step S25 with
The actual range obtained in step S24 is stated to be compared.
S24：Realtime graphic is analyzed to obtain front camera to the actual range of user's face.
In this step in S24, realtime graphic is analyzed, so as to obtain front camera to user's face information
Actual range.
Depth of field sensing module inside mobile terminal more can accurately measure in realtime graphic front camera to using
The actual range of family face, it is different from above-mentioned steps S23 to be set according to face information and takes pictures distance threshold, in this step S24
It is to obtain front camera apart from the actual range of face, using face center in realtime graphic as end points, detects preposition shooting
Head arrives the actual range of the end points.
The actual range of the front camera obtained in this step S24 to user's face is used in following step S25
In taken pictures with being set in above-mentioned steps S23 compared with distance threshold.
S25：Compare actual range and distance threshold of taking pictures.
In this step S25, take pictures distance threshold and above-mentioned steps will be set according to face information in above-mentioned steps S23
The actual range of front camera to user's face obtained in S24 is compared.
For example, distance range will be taken pictures compared with actual range, to show which value range active user belongs in,
When the difference of the posture according to hand-held mobile terminal, when be divided into it is near, in, remote three kinds of distance ranges when, equal to distance threshold of taking pictures
Middle distance can then be regarded as to take pictures scope, can then regard remote scope of taking pictures as more than distance threshold of taking pictures, less than taking pictures apart from threshold
Value can then regard scope of closely taking pictures as, i.e., when actual range, which is less than or equal to, takes pictures distance threshold, be then judged as closely
Scope of taking pictures or middle distance are taken pictures scope, now perform following step S26, when actual range, which is more than, takes pictures distance threshold, then
It is judged as scope of taking pictures at a distance, now performs following step S27.
S26：If actual range is less than or equal to distance threshold of taking pictures, enter triggering pattern of taking pictures manually.
By actual range and taken pictures in above-mentioned steps S25 after distance threshold is compared, when comparative result for it is actual away from
From less than or equal to take pictures distance threshold when, then enter and take pictures triggering pattern manually, into after triggering pattern of taking pictures manually, bag
Include and photographing instruction is obtained by physics shoot button or virtual photograph button, response photographing instruction is taken pictures.
Specifically, user takes pictures when carrying out self-timer using mobile terminal when judging that actual range is less than or equal to
During distance threshold, camera applications are set as triggering pattern of taking pictures manually, i.e., by pressing physics shoot button or clicking on related
Virtual photograph button on region obtains photographing instruction and taken pictures, wherein, secondary or physical bond can be the volume key on mobile terminal
Or other buttons.
For example, when user carries out self-timer in the position that actual range is less than or equal to distance threshold of taking pictures, arm can stretch
The position nearer to distance of mobile terminal face, now user's hand-held mobile terminal can maintain a relatively stable posture,
I.e. hand holds thing not exclusively hanging posture, hand and is not easy to shake, can be relatively easy to by finger press secondary or physical bond or
Person clicks on the action that the virtual key triggering on relevant range is taken pictures, and obtains desired image.
S27：If actual range is more than distance threshold of taking pictures, pattern is triggered into automatic camera.
By actual range and taken pictures in above-mentioned steps S25 after distance threshold is compared, when comparative result for it is actual away from
From more than take pictures distance threshold when, then into automatic camera trigger pattern, into after automatic camera triggering pattern, include examine
The physics shoot button or virtual photograph button for receiving photographing instruction are surveyed, if not receiving finger of taking pictures in preset time
Order, then obtain real-time voice, judge in realtime graphic or real-time voice with the presence or absence of triggering information, that is, judge be in realtime graphic
It is no crucial gesture or crucial expression to be present, or judge to whether there is crucial voice in real-time voice, if in the presence of response triggering letter
Breath is taken pictures.
Specifically, user takes pictures apart from threshold when carrying out self-timer using mobile terminal when judging that actual range is more than
During value, camera applications are set as that automatic camera triggers pattern, i.e., need not be by pressing secondary or physical bond or clicking on relevant range
Virtual key can triggering take pictures, automatic camera triggering mode can have it is a variety of, such as countdown, acoustic control etc. side
Formula, if user gets used to physics shoot button or the triggering of virtual photograph button, can still preset, it is necessary to explanation
Triggering pattern of taking pictures manually is used in time.If do not receive photographing instruction in preset time, then real-time language will be obtained
Sound, judge whether comprising triggering information, such as " self-timer ", " eggplant " etc. in the real-time voice, or judge in realtime graphic
With the presence or absence of crucial gesture or crucial expression, such as persistently smile 3 seconds or gesture of taking pictures " V " etc., clapped if so, then triggering is automatic
According to obtain desired image.
For example, when user is taken pictures under automatic camera triggering pattern, it is to wait for first 5 seconds, the wherein stand-by period is used
Family can be preset, and can also follow default setting, if not detecting, user is manually operated, be defaulted as user and be contemplated to be automatically
Triggering pattern of taking pictures rather than triggering pattern of taking pictures manually are taken pictures.Into after automatic camera triggering pattern, countdown 5 seconds is opened
Animation, and after 5 seconds complete take pictures, user can complete the adjustment of posture and expression in countdown process, during this period,
Whether having the triggering of smile self-timer, either the take pictures identification triggering or click on of the triggering of gesture self-timer or voice is taken pictures button or button,
If so, then immediately it can also complete to take pictures.
For above-mentioned steps S26 and step S27, in addition to reception is taken pictures triggering pattern switching command, and response is taken pictures tactile
Pattern switching instruction is sent out, automatic camera triggering pattern is switched to by triggering pattern of taking pictures manually, or pattern is triggered by automatic camera
