Embodiment one
As shown in Fig. 2 it gives a kind of background blurring image pickup method provided in an embodiment of the present invention, can from figure
To find out, the method can include：
S210, the first camera of control and second camera are shot to shooting main body simultaneously, and the first mesh is generated respectively
Logo image and the second target image；Wherein, the definition of the first object image is clear higher than second target image
Degree；
Here, it is necessary to explanation, first camera and second camera are arranged at the same of the same side of terminal
On one horizontal line, and the distance between first camera and second camera are less than default distance threshold.Described
One camera is used to obtain image definition first object image higher, and the second camera is used to obtain image definition
The second relatively low target image, that is, meet the target image of background blurring requirement.
The shooting main body included in S220, the extraction first object image；
S230, by from the first object image extract the shooting main body melted with second target image
Close, generate the 3rd target image.
It is to be appreciated that image co-registration refers to the advantageous information in comprehensive two or more source images, to obtain to same
More accurate, comprehensive and reliable iamge description of the same target of one scene.The technology takes full advantage of multiple images to be fused
In redundancy and complementary information, its mainly include Multi-Sensory Image Fusion at Pixel Level, feature level image interfusion method and decision-making
Level image interfusion method, step is implemented for every kind of method, and due to belonging to prior art, so here is omitted.
From step S210, the first object image is definition image higher, and second target image is
Meet the image of background blurring requirement, if it is possible to the shooting main body inspection that will be included in the first object image
Survey and extract, it is possible to by the shooting main body extracted from the first object image and second target image
Merged, shot that main body is clear, background blurring and image of true nature so as to obtain one, it is so prominent to shoot main body,
Enhancing visual effect.Specific fusion process schematic diagram may refer to Fig. 3, it can be seen that Fig. 3 (a1) is step S210
In the first camera to shooting the first object image schematic diagram that obtains when main body Lena shoots；Fig. 3 (a2) is to perform step
The result of rapid S220, i.e., the shooting main body Lena schematic diagrames in first object image, Fig. 3 (b) is the second shooting in step S210
Head is the shooting main body of Fig. 3 (a2) to shooting the second target image schematic diagram obtained when main body Lena shoots, Fig. 3 (c)
Lena and result schematic diagram that the Fig. 3 (c) is merged (detailed process corresponding step S230).It can be seen that carry out
During image co-registration, because the shooting main body in second target image and background image are fuzzy, therefore, after fusion
Shooting main body (i.e. foreground image) edge in image preferably can be transitioned into background image, so as to be that shooting main body can
Preferably be dissolved into background image, it is ensured that image (i.e. described 3rd target image) effect after fusion it is more true and from
So.
For step S210, in addition it is also necessary to explanation, terminal can be by adjusting the first camera and the second shooting respectively
Head and shoot the object distance between main body and adjust the definition of shooting image.For example, adjusting the first camera and shooting main body

During to default first clarity threshold, stop the regulation to the object distance between first camera and shooting main body, and it is raw
Into the first object image；Similarly, the object distance between the second camera and the shooting main body is adjusted, makes its intake figure
The definition of picture reaches the actual requirement of background blurring effect, can pre-set one less than first clarity threshold
Second clarity threshold, when the definition of the intake image reaches default second clarity threshold, stops to described the
The regulation of the object distance between two cameras and shooting main body, and generate the second target image.It should be noted that described first is clear
Clear degree threshold value and second clarity threshold are all based on the empirical value of practical application, and first clarity threshold is more than
Second clarity threshold, its purpose is to can respectively obtain image definition image higher (i.e. first mesh
Logo image) and the relatively low image (meeting the second target image of background blurring effect requirements) of an image definition.
Image definition described here is used for the readability of phenogram picture, and described image definition is higher, corresponding
Image is more clear；Conversely, described image definition is lower, corresponding image is fuzzyyer.Common image definition evaluation
Function mainly have grey scale change function (such as gradation of image variance function), gradient function (such as gradient of image and gray scale energy function,
Robert gradient and Laplacian operators) and gradation of image entropy function.Because the above-mentioned evaluation method for image definition is equal
Belong to prior art, therefore, here is omitted.

The greenery for enclosing form a sharp contrast；The shooting main body of such as described first camera is insect again, and insect is in overall color
And also can show different characteristics of image from the environment where it on texture features.
It is Position Approximate scope of the shooting main body in the first object image due to scratch the locking of figure scope, because
This, the whole characteristics of image for shooting main body can be speculated using characteristics of image of the main body in the range of stingy figure is shot.
S2201b, rim detection is carried out to the shooting main body according to described image feature, obtain the main body that shoots
Edge detecting information.
It should be noted that rim detection is the position that detection image feature changes, the edge of image refers to image
The value of middle pixel has the place of mutation, and different images gray scale is different, and obvious edge is typically had in the boundary of different images,
Can using this characteristic come segmentation figure as detection image edge.Edge is the line of demarcation for shooting main body and background area, is extracted
Edge could will shoot main body and background area makes a distinction.In the picture, border shows a termination for characteristic area and another
One beginning of characteristic area, the internal feature or attribute of border institute separation region are consistent, and different intra-zones
Feature or attribute are different, and rim detection is exactly realized using the difference of main body and background in certain picture characteristics is shot
, accessed gray scale, color or textural characteristics characteristics of image in such as above-mentioned step S2201a.Carried out to shooting main body
Rim detection can will just shoot main body and be made a distinction with other background areas where it, so that convenient to the shooting main body
