Based on above-mentioned mobile terminal, the embodiment of the invention provides a kind of photo processing method, Fig. 3 is according to the present invention
The flow chart of the photo processing method of embodiment, as shown in figure 3, method includes the following steps:
Step S302 is compared point to target scene in the multiple pictures of the target scene of predetermined angular shooting
Analysis, wherein the multiple pictures are shot by single camera；
Step S304 determines the foreground object and background object of the target scene according to the result of comparative analysis；
Step S306, according to the foreground object and background object photomontage determined.
Through the above steps, it is carried out pair to target scene in the multiple pictures of the target scene of predetermined angular shooting
Than analysis, wherein the multiple pictures are shot by single camera；The target scape is determined according to the result of comparative analysis
The foreground object and background object of elephant；According to the foreground object and background object photomontage determined, solve the relevant technologies
In the problem of shooting the effect of large aperture is difficult by single camera, by multiple pictures carry out analysis determine prospect and
Background synthesizes the photo of large aperture effect, improves user experience.
Object between 1m a to 5m carries out multiple pictures shooting from left to right, according to multiple shooting results,
Close foreground object is not moved in multiple shootings in picture position, and background passes through because having large change around movement
This mode judges the corresponding position of foreground object and background in picture, can be by blurring to background, and prospect sharpens, and closes
At the depth of field camera photos of large aperture.By comparing multiple pictures, judge that the less object of change in location (needs for foreground object
Carrying out the object of SD imaging) other are background object.
It can wrap to being compared and analyzed with target scene in the multiple pictures of the target scene of predetermined angular shooting
It includes: determining the situation of change of pixel in the multiple pictures by comparing the multiple pictures of the target scene.It is optional
, the foreground object of the target scene is determined according to the result of comparative analysis and background object may include: according to described more
The situation of change for opening pixel in photo determines the foreground object and background object of the target scene, wherein the pixel variation
Big is background object, and the pixel changes small for foreground object.Specifically, the shooting image for obtaining multiple pictures, according to
Depth of field camera obtains the depth information of each image, obtains the range information of the object distance camera in scene later.To multiple
Photo takes turns doing difference, i.e., any two different Xu images do subtraction, obtains difference, difference adds up later.Setting one
A threshold value T, accumulated deficiency d are less than the pixel of T, the as pixel of target object, because camera is rotated around object,
Distance of the object pixel apart from camera is held essentially constant, so difference is with regard to smaller.And background pixel is in each image,
With the movement of camera, distance change differs greatly.Refer to that difference can be by background pixel and object using threshold value T good person
Volumetric pixel distinguishes.
According to there are many kinds of the modes of the depth of field photo for foreground object and background object the synthesis large aperture determined, one
It may include: the depth of field photo that the background object is carried out to virtualization processing synthesis large aperture in a optional embodiment；By institute
State the depth of field photo that foreground object is sharpened processing synthesis large aperture；Large aperture is synthesized after enhancing the brightness of the foreground object
Depth of field photo；Alternatively, cooperating the depth of field photo of large aperture after enhancing the brightness of the foreground object.
In another alternative embodiment, may include: the background object is subjected to virtualization processing, and will be described before
Scenery body is sharpened processing, will be superimposed conjunction with the foreground object after Edge contrast by virtualization treated background object
At the depth of field photo of large aperture.Above-mentioned Edge contrast can using sharpening tool can quick focus blur foreground object side
Edge improves the clarity or focal length degree of foreground object, keeps the color of the foreground object distincter.
Enhancing and cooperating the depth of field photo of large aperture after the brightness of the foreground object may include: by increasing foreground object
Strong brightness, Image Warping enhances algorithm, and there are many algorithms.Here a kind of referred to as Adaptive contrast enhancement is taken
(ACE).ACE algorithm uses unsharp masking technology: image is divided into two parts first.First is that the unsharp masking of low frequency
The part (unsharp mask) can be obtained by the low-pass filtering (smooth, fuzzy technology) of image.Second is that radio-frequency component, it can
Unsharp masking acquisition is subtracted to cross original image.Then high frequency section is amplified (amplification coefficient, which integrates, increases CG as contrast) and is added to
In unsharp masking, the image of enhancing is finally obtained, the core of ACE algorithm is how to calculate CG.Unsharp masking
(unsharp mask) generally can be with the pixel by calculating for specific pixel corresponding to the low-frequency component of image
The pixel average of the regional area at center is realized.It is assumed that x (i, j) is the gray value that certain in image is put, regional area
Is defined as: centered on (i, j), window size is the region of (2n+1) * (2n+1), and wherein n is an integer.Certainly this
If window area is also not necessarily just square.The average value mx (i, j) of part, that is, low frequency part, can use following formula meter
It calculates:
And local variance sigma x (i, j) are as follows:
σ x (i, j) is exactly so-called Local standard deviation (LSD) in above formula.Defining f (i, j) indicates x (i, j) corresponding enhancing
Pixel value afterwards.Then ACE algorithm can be expressed as follows:
F (i, j)=mx(i, j)+G (i, j) [x (i, j)-mx(i, j)], (3)
Function G (i, j) therein is exactly the CG said above.CG is always greater than 1 under normal circumstances, such radio-frequency component
[x (i, j)-mx(i, j)] it can be enhanced.Here the calculation for providing a kind of CG is as follows:
G (i, j)=min (max (1, δ (i, j)/Gδ),10) (4)
σ x (i, j) is exactly so-called Local standard deviation (LSD), GδLocal variance for each point of entire image is average
Value, is provided by formula (5), and M and N are picture traverse and height.Min and max in formula (4), which are operated, limits the value of G (i, j)
In the range of [1 10], the edge of image or other change violent place, local mean square deviation is bigger, opposite full figure
The ratio of average difference also can be big, enhanced；In smooth region, local mean square deviation will very little, relatively entirely
The ratio of the standard deviation of figure also can be small, will not thus be enhanced.
