First embodiment
Fig. 3 is image pickup method basic flow chart provided in this embodiment, and this method can be applied to various types of
Terminal device, such as：The terminal devices such as smart mobile phone, tablet computer, laptop, and can be adapted for array phase
The terminal device of machine or camera with the principle of similitude, such as：It is imaged with array camera, with dual camera or with fly's eye
The terminal device of head.The image pickup method includes：
S301, the target screening-mode that terminal is determined according to the distance between object to be captured and background；Target shoots mould
Formula includes single camera screening-mode or multi-cam screening-mode；Terminal at least opens two under multi-cam screening-mode
Camera.
In the present embodiment, object to be captured is imaged body, is the main expressive object in photo, and background is entire
Other objects in areas imaging in addition to object to be captured, including physical location is in the object of imaged body front and back
Secondary expressive object in photo, for setting off imaged body by contrast.In practical applications, the distance between object to be captured and background
It is different, to which the performance in spatial depth sense is also different, in order to reach suitable shooting effect, need root
Corresponding screening-mode is determined according to distance between the two.It should be noted that in order to protrude imaged body in the present embodiment,
The photo that terminal taking obtains be by virtualization treated photo, the macro mode being arranged on terminal camera in the prior art,
Virtualization processing can be achieved in portrait mode of figure etc., as long as may be implemented in the camera of the virtualization processing under different camera screening-modes
Pattern each falls within the protection domain in the present embodiment, also, under single camera pattern with void when being shot under multi-cam pattern
It is different to change algorithm, virtualization algorithm can be used existing algorithm and realize that details are not described herein.
Single camera in the present embodiment includes front camera or rear camera.Multi-cam can be then multiple
The camera in homonymy (such as preposition or postposition) is arranged in body, can also be to move to the same side by terminal rotating, bending etc.
Multiple cameras can be in the horizontal direction or vertical direction setting, wherein horizontal when multiple cameras are arranged in homonymy
Direction refers to the direction parallel with terminal short side, and vertical direction refers to the direction parallel with terminal long side, certainly, multiple cameras
Can also be arranged otherwise, for example, in dual camera terminal by the line of two rear cameras and end level or
Vertical direction shape forms an angle, and a right angle is formed according to the line of three cameras to arrange also in three camera terminals
Three cameras of cloth.
Optionally, determine that the target screening-mode of terminal includes according to the distance between object to be captured and background：Judge
Whether the distance between object to be captured and background are more than pre-determined distance；If so, determining that target screening-mode is single camera
Screening-mode；If not, it is determined that target screening-mode is multi-cam screening-mode.
Specifically, pre-determined distance in the present embodiment is will be during actual photographed between each object to be captured and background
The characteristic value that distance is classified, when the distance between object to be captured and background are smaller, between object to be captured and background
Spatial depth sense difference it is smaller, user is it is generally desirable to the photo shot is higher to the virtualization degree of background, to more
To highlight object to be captured；And when the distance between object to be captured and background are larger, between object to be captured and background
The difference of spatial depth sense is larger, and object to be captured itself has just more been highlighted with respect to background, in this case, is shot
Photo background blurring degree it is relatively lower, can while showing object to be captured, blur effect more naturally,
Avoid the distortion of the photo under high virtualization degree.Such as photographed scene includes people and the tree positioned at people rear, wherein artificially waiting for
Reference object is set as background, in one case, when the distance between people and tree are closer, the prominent effect of the opposite tree of people when imaging
Fruit is not notable, at this time to highlight people, it is required that larger background blurring degree；And in another case, people and
The distance between tree farther out when, the protrusion effect of the opposite tree of people is relatively preferable when imaging, only needs at this time smaller background blurring
Degree makes imaging effect of the people in photo more highlight.
In practical applications, in order to protrude imaged body, it is common practice that it allows background to thicken, that is, blurs background, it is empty
The essence for changing background is that each point of background is made to be in disperse round shape on sensitized lithography, and disperse circular diameter is bigger, and background is more empty.
For slr camera, virtualization can be adjusted by changing aperture and the focal length of camera, however it is narrow in certain internal structures
Larger camera module can not be assembled when in small terminal, to be imitated by adjusting aperture and focal length to adjust virtualization
Fruit.Virtualization effect in the present embodiment is realized by algorithm, is based on single camera screening-mode and dual camera screening-mode institute
The difference of the camera module of use, the i.e. difference of camera quantity, imaging data different from acquired in the two, to need to adopt
With different virtualization algorithms, and then the performance blurred in effect also embodies difference.In the present embodiment, when object to be captured with
Screening-mode is set as single camera screening-mode when the distance between background is larger, while meeting background blurring effect
Camera resource can be preferably saved, image taking speed is promoted and reduces power consumption of terminal, and between object to be captured and background
Distance it is smaller when screening-mode is then set as dual camera screening-mode, to realize single camera screening-mode in the bat
Take the photograph the inaccessiable more excellent virtualization effect of lower of scene.
Optionally, judge the distance between object to be captured and background whether more than pre-determined distance include：Judge whether to connect
Receive the parameter regulation instruction of preset kind input by user；If so, judging that the distance between object to be captured and background are big
In pre-determined distance.
In practical applications, the determination of the comparison result of the distance between object to be captured and background and pre-determined distance can be with
It is determined, such as can be measured between object to be captured and background by the infrared sensor being arranged in terminal by terminal itself
Distance, further again by terminal realize compare；In the present embodiment, it can also be the determination that result is compared by user,
I.e. user determines the comparison result of the distance between object to be captured and background and pre-determined distance according to experience, and in terminal
The correspondence being preset between parameter regulation input by user instruction and comparison result, when user according to determining distance at end
When inputting corresponding parameter regulation instruction on end, terminal gets whether the distance between object to be captured and background are more than in advance
If distance.
Optionally, the parameter regulation of preset kind, which instructs, includes：The instruction of shutter parameter regulation, white balance adjusting instruction, sense
Any one of luminosity regulating command, interval continuous shooting regulating command.
Specifically, in the present embodiment, the instruction in addition to parameter regulation input by user instruction is instructs except manual focus
Shi Jun is determined as that the parameter regulation for meeting condition instructs, and terminal can then be instructed based on these parameter regulations input by user and determine bat
It takes the photograph the distance between object and background and is more than pre-determined distance, to call single camera screening-mode；In further embodiments,
