Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are some of the embodiments of the present invention, instead of all the embodiments.Based on this hair
Embodiment in bright, the every other implementation that those of ordinary skill in the art are obtained without creative efforts
Example, shall fall within the protection scope of the present invention.
Under certain scenes of taking pictures, often existing highlights domain in viewfinder range, and have low light region.And when taking pictures,
The focus point and survey luminous point of acquiescence are often positioned in the center or some specific region of picture, then being surveyed when based on low light region
When photo-beat is shone, overexposure phenomenon will occur in background parts, cause photo that details cannot be distinguished.
For example, when carrying out self-timer, if bias light is very strong, the brightness of portrait area can be far below background area
Brightness, and if carrying out surveying photo-beat photograph based on portrait area, the brightness of portrait area can be shown normally, but background area is bright
Degree then excessively high can lead to overexposure.
And when being taken pictures based on highlights domain, then low light region can then be shown secretly, and photo can not area in display
Point.
In this specification one or more embodiment, after receiving photographing instruction, the mesh in shooting area can be identified
Region is marked, luminous point determination will be surveyed and carry out survey light in the target area, and shoot photo and obtain the first image；Then luminous point will be surveyed
It determines and carries out survey light in nontarget area, and shoot photo and obtain the second image；Again by target area in described first image
The image of nontarget area carries out splicing synthesis in image and second image, obtains third image as photo.In this way,
The target area and nontarget area of the photo of acquisition all can be obtained target area and nontarget area all clear photographs.
For ease of description, in this specification one or more embodiment, the executive agent of photographic method can have bat
According to terminal device of function, such as smart mobile phone, tablet computer, digital camera etc..In addition, the executive agent of this method can also
It is the software itself for controlling camera and taking pictures.Hereinafter by taking executive agent is camera as an example, the embodiment of this method is introduced.
It is appreciated that it is a kind of illustrative explanation that the executive agent of this method, which is camera, it is not construed as the limit to this method
It is fixed.
In this specification one or more embodiment, the implementation process schematic diagram of photographic method is as shown in Figure 1, under including
State step：
Step S100：After receiving photographing instruction, the target area in shooting area is identified；
Photographing instruction, which can be used for controlling camera, takes pictures, for example, photographing instruction, which can be user, passes through the fast of pressing camera
Door key triggering, or in intelligent terminal, photographing instruction can also be that user is pre- in human-computer interaction interface by clicking
If take pictures what button was triggered.The triggering form of photographing instruction is not specifically limited in this specification.
Shooting area can be the viewfinder area of camera, and general shooting area can be anti-in real time in the form of preview image
Feed user.
Target area can be the region where object in shooting area, which can be according to object come really
Fixed.In the specific implementation, it may be predetermined that the feature of object, it in this way can be according to the feature of object, to identify
Region in shooting area where object, i.e. target area.In the specific implementation, the feature of object can be preset,
According to the feature of object, to identify the region where object when shooting.
At the region where the feature recognition object according to object, the preview graph of shooting area can be first obtained
Then picture carries out image recognition to preview image, i.e., identifies the object in preview image according to the feature of object.If
Identify target image, then it can be using the region where target image as target area.
In one embodiment, object can be people, then target area is the region where portrait, then
When identification object region, it can be identified based on portrait feature.Specifically in identification, the preview graph of shooting area can be first obtained
Picture is then based on pre-set portrait feature, image recognition is carried out in the preview image, if known in the preview image
It is clipped to portrait, then using the region where portrait as target area.
For example, under the self-timer mode of camera, since the object of shooting is often people, then self-timer can be pre-set
Target area under pattern is the region where portrait.In this way when taking pictures, you can identify portrait region.
If recognizing target area in shooting area, S102 is entered step, otherwise continuing to identify in shooting area is
It is no that there are target areas.
Step S102：Luminous point determination will be surveyed and carry out survey light in the target area, and shoot photo and obtain the first image；
Luminous point will be surveyed to determine when some position carries out survey light, it can be by adjusting optical parameter when taking pictures so that survey light
The brightness of position reaches a certain default value, and the default value is often so that photometry region shows normal value, by exploit person
Member presets.So-called display is normal, and usually in the case where visually observing, brightness of image both too high will not lead to overexposure, also not
It can secretly cause image unclear very much.
So, when luminous point determination will be surveyed when the target area carries out survey light, the brightness of target area can be made to show
Normally, in the first image shot at this time, the brightness of target area will be shown normally.
Step S104：Luminous point determination will be surveyed and carry out survey light in nontarget area, and shoot photo and obtain the second image；
Region in nontarget area, including shooting area in addition to target area, that is to say, that carried out in nontarget area
When surveying light, a part of region that can be in shooting area other than target area carries out surveying light and take pictures, such as to target area
Some outer position carries out surveying light and shoots photo, or can also to target area outside multiple position distributions carry out surveying light simultaneously
Shoot photo.
The brightness difference of target area and nontarget area can be more than given threshold, in this way by respectively to target area
Domain and nontarget area carry out survey light, it is ensured that and the image of target area and nontarget area can normally show, without
There is overexposure or excessively dark phenomenon.Here the specific value of given threshold can be preset by developer, the present embodiment
This is not specifically limited.Under normal circumstances, it if the luminance difference is more than given threshold, takes pictures based on target area
When, nontarget area then will appear overexposure phenomenon, and if when luminance difference is not more than the given threshold, nontarget area will not
There is overexposure phenomenon.
In one embodiment, it can will survey luminous point to determine in some position of nontarget area, then be directed to the position
It sets and carries out surveying light and shoot photo, obtain the second image.It determines when the nontarget area carries out survey light, can make when luminous point will be surveyed
The brightness for obtaining nontarget area shows that normally in the second image shot at this time, the brightness of nontarget area will be shown
Normally.
Certainly, nontarget area may brightness and inhomogenous, then can be to multiple and different positions of nontarget area point
Survey light is not carried out.In one embodiment, different location of the luminous point determination in nontarget area can will be surveyed, is then directed to every
A position, which carries out surveying respectively, light and shoots photo, obtains each second subgraph shot under each survey luminous point, then to each the
Two subgraphs are synthesized, and the second image is obtained.In this way, the second image is also to be obtained after carrying out survey light for multiple points, carry
The high photographic quality of second image.
It should be noted that if carrying out multiple survey photo-beat to nontarget area and taking the photograph multiple pictures, it can be by shooting
Multiple pictures are known as the second subgraph, and the image obtained after being synthesized to the second subgraph is known as the second image.In this way, to non-mesh
Mark region carries out survey photo-beat and can be described as the second image according to obtained image, is quoted when facilitating subsequent descriptions.It is used in the present invention
" first ", " second ", the terms such as " son " can be used for distinguishing different things, to clearly articulate core of the invention thought,
And it is not construed as the absolute limit to the present invention.
When being synthesized to obtained multiple second subgraphs, it may be determined that in multiple second subgraphs at same position
Pixel pixel average.In practical applications, it may be determined that each pixel of same coordinate in multiple second subgraphs
The pixel value of point, then takes the average value of those pixel values, obtains pixel average, in this way, picture at each position can be obtained
The pixel average of vegetarian refreshments.
It is then possible to by the pixel value of pixel is set as at first position in the second image, first in the second subgraph
The pixel average of pixel at position.In one embodiment, in the second image at each position pixel pixel
Value, could be provided as the pixel average at obtained same position calculated above.
By the average value of capture element, it can so that brightness is more uniform on the whole for second area in the second image, no
It will appear the situation that certain places are excessively bright or certain places are excessively dark so that the overall effect of image is preferable.
In one embodiment, target area is portrait area, nontarget area is carried out surveying photo-beat shine when, can be with
It carries out surveying light in the first position of nontarget area and shoots photo, which is located at the upper left corner outside portrait area,
It can also carry out surveying light in the second position of nontarget area and shoot photo, the second position is located at the upper right outside portrait area

Upper angle and the upper right corner are often the region residing for the higher source luminances such as light, the sun, then, by the upper left corner and the upper right corner point
Survey light is not carried out, can survey light preferably be carried out to the background in portrait scene so that the background pictures obtained under portrait scene
It is more clear.
In the specific implementation, the specific location of first position in the picture can be, lengthwise position apart from portrait area most
The distance of low spot is the 3/4 of people's image height degree, and lateral position is that portrait area right hand edge is between image right hand edge at lengthwise position
Central point.The specific location of the second position in the picture can be that distance of the lengthwise position apart from portrait area minimum point is
The 3/4 of portrait height, lateral position be, portrait area left hand edge is to the central point between image left edge at lengthwise position.
Step S106：By nontarget area in the image of target area in described first image and second image
Image carries out splicing synthesis, obtains third image as photo.
Based on above-mentioned steps, normal first image of target area brightness can be obtained and nontarget area brightness is normal
Second image, it is possible to which the image of nontarget area in the image of the first objective area in image and the second image is carried out
Splicing synthesis, obtains third image as photo.
In one embodiment, the image of the first objective area in image can be extracted, then by the target area of extraction
The image in domain covers the target area in the second image, obtains third image.In this way, the figure of third objective area in image
The picture as normal image of brightness, the image of nontarget area is also the normal image of brightness.
In one embodiment, due to having had identified target area in step S100, then can be according to step
The target area identified in S100, in the first image target area and nontarget area be split, obtain target area
The image in domain.
In another embodiment, it is contemplated that the target area identified in step S100 may be obtained with follow-up shooting
There is deviation in target area in first image, then when extracting the image of target area, it can be according to image to be identified
Feature identifies target area in the first image, then in the first image target area and nontarget area divide
It cuts, you can obtain the image of target area.
In this way after obtaining the image of target area, you can by nontarget area in the target area image and the second image
Image carry out splicing synthesis.The image of finally obtained third image target area and the image of nontarget area all respectively into
Survey light is gone, it is ensured that lightness is normal, is not in overexposure phenomenon, dark phenomenon will not occurs, relative to existing
For technology, the quality of photo is improved.
It should be noted that the first image shot after surveying light in the application, the second subgraph, second image etc.
The size acquiescence of image, image is identical size,, can if its size is different to carry out subsequent segmentation and merging
Registration process first is carried out to image.In addition, the difference between each viewfinder range of image when shooting can be as small as possible,
Therefore the time interval when shooting picture can be short as much as possible, causes shooting to obtain to avoid due to outside causes such as shakes
Multiple pictures between viewfinder range gap it is larger.
