Illustratively, if the filming apparatus is smart mobile phone, and gyroscope is both provided in general smart mobile phone
Sensor with acceleration transducer etc. for measuring mobile phone posture information, can be according to gyroscope and/or acceleration transducer
Determine the jitter parameter of smart mobile phone.
S111, the ambient brightness information for obtaining predeterminated position in the coverage of the filming apparatus；Wherein, described pre-
If position includes at least two preset coordinates.
The coverage of the filming apparatus is：When the filming apparatus is shot, the scene domain that can take.
Illustratively, as shown in Fig. 2, if shooting the certificate photo of personage 13, the coverage 11 by filming apparatus 10
Background board region 12 including the personage 13 and personage behind.
Wherein, the predeterminated position in the coverage is the position that can be used for weighing brightness case in coverage,
Predeterminated position can be：Preset coordinate in the corresponding digital picture that the coverage of filming apparatus shooting generates.
The ambient brightness information is the information for the globality brightness case for embodying the coverage；The ambient brightness
Information can be according to determined by the corresponding luminance parameter of at least two preset coordinates.The predeterminated position can be that system is pre-
If being configured according to the user's choice.Illustratively, if the predeterminated position includes two preset coordinates, two
Preset coordinate is located at the top and bottom of the digital picture, and if the corresponding brightness ginseng of the preset coordinate of the upper end
Number is 80, and the luminance parameter of lower end is 60, then can determine that the light source in the coverage is located at upper end, the shooting model
It includes upper bright lower dark to enclose middle brightness case, and ambient brightness information includes upper bright lower dark brightness case.
