In embodiments of the present invention, when photographic head enabled instruction being detected, acquisition for mobile terminal current environment brightness, and
Initial exposure time and initial exposure offset it is set according to current environment brightness, and this mobile terminal is by the beginning of based on arranging
Beginning time of exposure and initial exposure offset start described photographic head.Initial exposure time owing to using when photographic head starts is
Arrange based on current environment brightness, i.e. this initial exposure time is to adapt to current environment brightness so that when photographic head starts
Use this initial exposure time that the phenomenon of flicker can't occur, improve the experience of user.Further, by based on working as
Front ambient brightness arranges initial exposure offset, enabling improve scintillation when photographic head starts further.
Refer to Fig. 9, the refinement functional module of module 801 is set in the 4th embodiment shown in Fig. 8 of the present invention second
Schematic diagram, this second arranges module 801 and includes: second searches module 901 and compensate and arrange module 902.
Second searches module 901, for searching the mapping relations between ambient brightness and the exposure bias value pre-set,
Determine the exposure bias value corresponding with described current environment brightness；
Compensation arranges module 902, for according to the exposure bias value that described current environment brightness is corresponding arrange described initially
Exposure bias value.
In embodiments of the present invention, pre-set the mapping between ambient brightness and exposure bias value in mobile terminal to close
System, wherein, the mapping relations between this ambient brightness and exposure compensating time can dispatch from the factory it at mobile terminal or photographic head
Front mode based on experiment obtains, and writes in the parameter storage area of photographic head or mobile terminal.
In embodiments of the present invention, second ambient brightness and the exposure bias value that lookup is pre-set by module 901 is searched
Between mapping relations, determine the exposure bias value corresponding with this current environment brightness, and by compensation arrange module 902 utilize with
Exposure bias value corresponding to this current environment brightness arranges initial exposure offset.
In embodiments of the present invention, by using in mobile terminal between ambient brightness and the exposure bias value pre-set
Mapping relations so that mobile terminal is when photographic head enabled instruction being detected, it is possible to based on this ambient brightness and exposure compensating
Mapping relations between value determine the exposure bias value corresponding with current environment brightness, and arrange initial exposure offset, it is possible to
Effectively realize the setting of initial exposure offset.
