Subject, then determine that terminal and the distance of the second subject can be referred to as during standard shooting distance
Two distances.
Terminal receive it is external issue for the setting of standard shooting distance to be set to instruct when, in terminal and the second quilt
During the distance change of reference object, by the dual camera of terminal with prefixed time interval to second subject
Image be acquired, to obtain the image to be selected between terminal and the second subject in different distance, receive outer
Portion, which treats, to be selected image and selects instruction, according to select instruct the selected standard picture computing terminal to shoot standard picture when with mark
Second distance between quasi- image, using the second distance as standard shooting distance.It is understood that in some scenes
In, can mobile phone camera be opened by such as user, " double to take the photograph ranging automatic camera " function be opened in camera configuration, mobile phone can
User to be prompted to hold mobile phone slowly away from the second subject shot, slowly away from during, mobile phone
The image of the second subject is shot with prefixed time interval by dual camera, wherein default time interval can
With the shorter of setting, then obtained standard shooting distance can be more accurate, and what can also be set is longer, then user need not wave
Take the too many time in the selection of photo to be selected.Several picture numbers that mobile phone can automatically snap in this process, obtain
To the image to be selected between terminal and the second subject in different distance, every picture cell phone to be selected may all can
Its corresponding distance is calculated, user can select oneself to think that shooting effect is the most satisfied in these images to be selected
One, then terminal will receive treat select picture select instruction, then system can most make user by this
Satisfied image calculates the second distance corresponding to this image, then the second distance can serve as active user's setting
Standard shooting distance.
In some examples, determining for standard shooting distance can also be that programming personnel pre-installs directly progress in shooting software
Standard shooting distance that is setting or such as being obtained from media such as networks, can specifically take from the official of terminal
The standard shooting distance of other mobile phone users setting is got on business device, a kind of that highest standard of access times is therefrom selected to clap
Standard shooting distance of the photographic range as this mobile phone.According to different user demands, the setting of standard shooting distance can be more
Kind of mode, user, which can carry out it redefining standard shooting distance, can also directly use Current standards shooting distance, such as
Fruit may prompt user to carry out determining for standard shooting distance currently without standard shooting distance so mobile phone.
After default standard shooting distance is determined, it is possible to by the first distance and pre-set standard shooting distance
It is compared.
S303：When definite first distance matches with standard shooting distance, the camera automatic collection of control terminal
The image data of one subject.
After obtaining the first distance and being determined standard shooting distance, it is possible to by the first distance with it is pre-set
Standard shooting distance is compared, and according to result of the comparison, when such as the first distance matches with standard shooting distance, then can be controlled
Camera processed automatically snap the first current subject.But in the first quilt of camera automatic collection of control terminal
Before the image data of reference object, we can also determine whether the first subject and the second subject are same
Object, and when determining to belong to same target, then control terminal automatic camera；Further, can also before automatic camera,
Auto-focusing processing is carried out to first subject according to first distance.Such as in a scene, user uses
It is using the face of oneself as the second subject during pre-set standard shooting distance, then after being provided with,
In shooting afterwards, mobile phone may first judge the first subject whether with the second subject for same target,
For even active user when carrying out self-timer, mobile phone can directly judge that the face of active user is exactly to be determined standard
Face during shooting distance is, it is necessary to which explanation is that this arbitration functions can be realized by functions such as recognitions of face.
After the completion of judgement, mobile phone is chosen the second distance of characterization image to be selected when can be directly according to definite standard shooting distance
Standard shooting distance during as current self-timer, and directly according to determine standard shooting distance when camera aperture focusing situation come
The auto-focusing of this self-timer is carried out, the time of handset processes focusing is so shortened, efficiency during user's self-timer can be promoted.
On this basis, it is to be understood that in some scenes, if the first subject and second is taken pair
As be not for same target, if but the first subject and the second subject are all faces, simply according to face
Identify it is not same face, mobile phone current first subject can equally be carried out according to the first distance and the second quilt
The same auto-focusing processing of reference object, because it is all face to be all based on the first subject and the second subject
On the basis of the shooting that carries out, it is possible in the case of being all self-timer, the situation difference focused in fact is not very big.Another
In a little examples, if the first subject and the second subject, which are all certain similar objects, such as claps landscape and whole man
Object etc., then can similarly carry out similar processing.
When definite first distance matches with the standard shooting distance, in order to obtain a preferably matching
Effect avoids user from wasting the too many time when finding the shooting distance of automatic shooting, can be that the first distance and standard are clapped
Matching between photographic range sets certain margin of error.Wherein, in ideal conditions, if it can be determined that the first distance etc.
When standard shooting distance, then it can determine that the first distance just matches with standard shooting distance.But in some scenes
In, we are required for as the first distance allowable error certain with the match settings of standard shooting distance, to avoid the first distance
It is difficult to match the situation for causing to automatically snap functional failure with standard shooting distance, it is to be understood that in allowed limits,
First distance of judgement of " rough " is as the photo that the standard shooting distance matches and automatically snaps out possible acquisition
The accreditation of user, it is possible to which being set later by the error amount for allowing the definite value plus-minus of standard shooting distance becomes one
A value range can think the first distance and the standard shooting distance phase after the first distance falls into the value range
Match somebody with somebody；It can also judge that the first distance with the standard shooting distance is close by other mechanism, can equally recognize
Match for the first distance and the standard shooting distance.
It should be noted that in order to avoid it is possible that after the first distance falls into the value range of standard shooting distance just
The function of automatic camera is ceaselessly carried out, interval time and the focusing time of automatic camera can be set, for example works as user
When holding mobile phone progress self-timer, current first distance falls into the value range of standard shooting distance, will not take pictures immediately, but
Focusing time, which can be reserved, waits mobile phone to complete automatic camera again after focusing, can in a short time will not be again after automatic camera
Secondary automatic camera can so avoid the occurrence of the situation for shooting very multiple pictures.The interval time of automatic camera and focusing
Time can be time set by user or mobile phone researcher after research when pre-installing cell phone software
The relatively reasonable time set or other rational set-up modes.
It, can be to image after the image data of first subject described in camera automatic collection in control terminal
Data are analyzed, if it is decided that when the first subject is face, face that can be according to the selection of user to taking
Image carries out U.S. face processing, in other scenes, if it is decided that the first subject for it is non-face when, equally can according to
The selection at family carries out a degree of landscaping treatment to the inhuman face image taken, for example the night photograph shot can be to it
It carries out eliminating the processing such as furious or reduction photo noise so that entire photo obtains beautification to a certain extent.
In order to which the photo for ensureing to make automatic shooting reaches a better effect, make subject at the center of picture,
In some embodiments, can also before the image data of the first subject of camera automatic collection of control terminal,
The imager coordinate of the current image that is taken of acquisition, and compared with the coordinate of mobile phone screen, to ensure to be taken, image is in
In mobile phone screen.Under some scenes, it may ensure that the first subject is in the scope of screen when shooting
Interior, the photo that such automatic camera comes out is only possible to the accreditation that larger probability obtains user, for example user is carrying out self-timer
In the process, mobile phone captures the current face mask information of user by camera, if the mobile phone back that user uses
Camera is shot, i.e., user may cannot see mobile phone screen, and one whether cannot can be also obtained to face preferably
Effect of taking pictures be guaranteed, user stretch out hold the arm of mobile phone when, may it is current first distance met mark
The requirement of quasi- shooting distance, but camera is directed at the face of oneself by user not yet, it is possible that only there are one half faces in mobile phone
In screen, then mobile phone captures the current face mask information of user and judges the imager coordinate of face not default at this time
In coordinate range, then would not also be automatically snapped.When user by mobile phone camera be targeted by oneself face namely this
When user face when can completely appear in mobile phone screen, mobile phone may judge the imager coordinate of face in preset coordinate model
In enclosing, automatic camera may will be carried out after focusing.It should be noted that judging imager coordinate not in preset coordinate model
When enclosing interior, imager coordinate and the offset of preset coordinate scope are calculated, alarm prompt prompting user is generated according to offset,
For example detect that the face of user is imaged not in the range of preset coordinate, for example not in screen, mobile phone can send language
Tone alerts such as drip drop sound, can also be shaken to inform user, it is to be understood that if the face of user is imaged on screen
Lower section, mobile phone capture the current face mask information of user at this time and judge the current face of user some
In the lower section of screen, it is possible to send voice prompt " mobile phone please be move down " to inform that user is directed at camera.
There can also be auditory tone cues when mobile phone will carry out automatic camera, for example " drop drop " sound or be shaken,
To prompt user that automatic camera has been completed.
The general existing mobile phone of acquiescence is all preposition single camera, postposition dual camera, if front camera is also double
Camera, then distance measurement function can also be carried out when taking pictures with preposition dual camera by putting dual camera before use.
The present embodiment provides a kind of automatic camera control method, needed for existing user when taking pictures using camera by
Key is shot, but because the defects of shooting key takes pictures, influences user experience can not easily be pressed；By obtain terminal with
The first distance between first subject, by first distance compared with pre-set standard shooting distance,
When definite first distance matches with the standard shooting distance, control described in the camera automatic collection of the terminal
The image data of first subject；Realize user only needed when taking pictures by terminal be moved to the shooting of default standard away from
It takes pictures from can be realized, the effect of shooting key need not be pressed again, then by being likely to occur order to photo during automatic camera
The unsatisfied problem of user is more set, solve in the shooting of existing target and self-timer it is complicated for operation, be difficult to manually by
The problem of lower shooting key, users' satisfaction degree is low.
Second embodiment
In order to be better understood on the present invention, the present embodiment combines the specific example of an automatic camera, provides one kind
The specific method of automatic camera control, this embodiment assumes that user is taken pictures using mobile phone, in order to facilitate understanding and illustrating,
The present embodiment equally using nouns such as the first distance, second distance, the first subject and the second subjects, specifically contains
Justice is see first embodiment.Fig. 6 is the refined flow chart for the automatic camera control method that second embodiment of the invention provides, should be certainly
Dynamic camera control method includes：
S601：User opens the automatic photo function of mobile phone.
When user plays outside, may need at any time using Self-timer, but may not carry again compared with
The instruments such as the self-shooting bar and tripod that take up space.In the present embodiment, the mobile phone that user uses may be preposition single camera, after
Put the mobile phone of dual camera, put before use stretched when single camera is taken pictures shooting key may be pressed after arm again will be very numb
It is tired and inconvenient, and user wishes to obtain a better shooting effect, in be intended to using postposition dual camera carry out from
It claps, screen may not be seen when reversely holding mobile phone.Then user opens the automatic photo function of mobile phone camera, uses
The function of the automatic camera of mobile phone, it is assumed that user is to use this function for the first time, and programming personnel may be not pre- in mobile phone
Standard shooting distance is set when filling software.
S602：User determines the standard shooting distance of mobile phone.
After the automatic photo function of mobile phone camera is opened, since user is to use automatic photo function and volume for the first time
Cheng personnel do not set standard shooting distance, then mobile phone can first prompt user need to take pictures to standard distance into
Row determines.In the present embodiment, user can be prompted to need reversely to hold mobile phone, by mobile phone postposition dual camera alignment user's
Face, from bending arms to stretching, it is slowly moving reversely to hold mobile phone for this section of arm.During movement, mobile phone meeting
Multiple are carried out to the face of user to take pictures, each photo mobile phone can all calculate corresponding second distance, in mobile phone completion pair
The sampling of second shooting object can prompt user to select a photo the most satisfied from sample after taking pictures.User selects
One photo of the best results of taking pictures oneself thought, selection complete after, mobile phone can prompt user determine standard shooting away from
From finishing, automatic camera can be carried out.After a photo has been selected, mobile phone can be believed automatically according to the image data in photo
Breath calculates second distance, then using this second distance as standard shooting distance.
In some instances, the standard shooting distance of terminal can also be directly is set by programming personnel or researcher
It puts, it is self-timer mode that may just need user's selection, landscape configuration, and the isotypes such as personage's pattern select different standards to clap
Photographic range, different screening-modes are to have corresponded to different shooting demands in fact, so the automatic camera of different screening-modes
Standard shooting distance can also have differences, for example standard shooting distance may be at 1 meter or so under self-timer mode, and landscape configuration
Standard shooting distance may be between 50 meters to 100 meters, the standard shooting distance of personage's pattern may be at 10 meters or so.It can be with
Understand, screening-mode is diversified in fact, however it is not limited to above-described three kinds, only to facilitate understanding, no
It can limit the scope of the invention.
Automatic photo function is opened in user and has selected that after corresponding exposal model automatic camera can also be carried out,
Without carrying out determining for standard shooting distance, but if user is less satisfied with the photo that current automatic camera comes out,
Can also be realized in setting to automatic camera distance again determine.In some instances, if terminal judgement is different use
When family is taken pictures using mobile phone, probably due to user is different to the requirement taken pictures, it is possible that user can be prompted to need again
Standard shooting distance is determined.
On this basis it will be appreciated that user for determining the different demands of standard shooting distance, i.e. take pictures mould by difference
Standard shooting distance during formula is different.For example user can select self-timer mode, to the automatic camera standard of self-timer mode
Shooting distance is determined, then user in self-timer mobile phone may will select this second distance as standard shoot away from
From；User is also an option that personage's pattern, and to shooting, other people automatic camera standard shooting distance is determined, then Yong Hu
Mobile phone may will select this second distance as standard shooting distance when shooting other people.So standard shooting distance of mobile phone
There can be different second distances to support that similary user can also be to different shooting moulds as data under different screening-modes
Standard shooting distance under formula carries out redefining operation.
