Illustratively, if it is true according to the coordinate in facial image region and the coordinate outside facial image region
Brightness of the brightness less than the region outside facial image for determining the region of facial image, then can correspond to the raising shooting time for exposure,
So as to improve the brightness in the facial image region in the digital picture formed after shooting.
S152, the corresponding luminance parameter of at least two preset coordinates is obtained respectively.
S153, Benchmark brightness parameter is determined according at least two preset coordinate and corresponding luminance parameter, and really
It is set to ambient brightness information.
S154, determine the shooting according to the jitter parameter and the luminance information be continuously shot parameter.
The specific implementation mode of aforesaid operations can refer to associated description above, and details are not described herein.
Whether include facial image in coverage of the embodiment of the present application by judging the filming apparatus, and according to people
The location determination predeterminated position of face image can further increase the accuracy of ambient brightness information, and be believed according to ambient brightness
What is shot determined by breath is continuously shot parameter and can optimize the photo of shooting.
Fig. 8 is that another kind provided by the embodiments of the present application is taken pictures the flow diagram of optimization method, in above-mentioned arbitrary implementation
On the basis of the technical solution that example is provided, optionally, as shown in figure 8, this method includes：
S160, when being shot by filming apparatus, determine the jitter parameter of the filming apparatus.
S161, luminance information in the coverage of the filming apparatus is obtained.
When S162, the object in the coverage focal zone of the filming apparatus relatively move, described in acquisition
The moving parameter of object；Wherein, the focal zone includes at least two objects, and the relative movement occurs between object
Relative movement.
Wherein, the filming apparatus is when being shot, because photographed scene is three dimensions, the difference in coverage
The distance of object and filming apparatus is different, so filming apparatus generally can be there are one focal zone, to make focal zone
In object can clearly be taken.So the object in focal zone is usually the master in the desired photo shot of user
Want object.The focal zone can be filming apparatus automatic identification and systemic presupposition, can also be user's actively setting.
If the object in the focal zone is waited when shooting has occurred movement, it is also possible in the photo for leading to shooting
The fuzzy problem of object, so whether the object in the further focal zone for judging coverage moves, so as to basis
Further adjustment is continuously shot parameter to the moving parameter of object.
General focal zone includes at least two objects, such as be taken main body and background.If shot subject is subjective
Movement has occurred, then there is relative movement between shot subject and background.And it is moved to lead if it is filming apparatus
When the object in focal zone being caused to have occurred mobile in camera lens, shot subject and background can move simultaneously.
So whether can be relatively moved according to the object in focal zone to determine the object in focal zone
Whether movement has occurred in subjectivity, and then can determine the moving parameter of the object.The moving parameter is to embody focal zone
In object occur movement parameter, can be object movement speed, displacement distance and translational acceleration in it is at least one.
Table, the jitter parameter, the moving parameter of the object and described bright can be determined according to preset continuous shooting parameter
What degree change information determined the shooting is continuously shot parameter.The preset continuous shooting parameter determines in table to include shake ginseng
Number, the moving parameter of object, brightness change information and the mapping relations for being continuously shot parameter；So can according to jitter parameter,
The moving parameter and brightness change information of object determine it is corresponding be continuously shot parameter, shot as filming apparatus continuous
Acquisition parameters.
It should be noted that the execution sequence of operation S162 is not limited to shown in attached drawing, operation S162 only needs operating
It is executed before S163.
S163, basic parameter is determined according to the jitter parameter；Believed according to the moving parameter of the object and the brightness
Breath adjusts the basic parameter, and obtain the shooting is continuously shot parameter.
Wherein, because the jitter parameter of filming apparatus determines the effect of the benchmark of the image captured by filming apparatus.Show
Example property, if filming apparatus shake is larger, though the object in coverage does not move, and with good
Stable light, it is also possible to take unclear photo.So determining basic parameter according to the jitter parameter first, in turn
The basic parameter is adjusted according to the moving parameter of the object and the brightness change information, can improve and be continuously shot parameter
Accuracy.
The embodiment of the present application is relatively moved according to the object in the coverage focal zone of the filming apparatus
When, the moving parameter of the object is obtained, and according to the jitter parameter, the moving parameter of the object and the brightness change
What information determined the shooting is continuously shot parameter, can be carried according to the moving parameter of the object in the focal zone of coverage
Height is continuously shot the accuracy of parameter.
