Description
Technical field
The present invention relates to camera work field, the method for more particularly to a kind of light filling of taking pictures and setting
Standby.
Background technology
Have become as the behavior of very normality in life, when needing, people by mobile phone photograph
Habitually take out light mobile phone record splendid moment.But when shooting night scene,
Mobile phone always can not take satisfactory effect, and this is the intrinsic limitation of mobile phone photograph.Study carefully
Its reason is that, the small size of mobile phone camera limits the size of internal sensor, thus
Have impact on the photosensitive property of photographic head, imaging capability is naturally just poor under the low light conditions such as night.
In order to solve this problem, flash lamp just arises at the historic moment.Flash lamp is to increase camera exposure
One of mode of amount, can beat bright surrounding scenes under half-light environment, thus making up insufficient light,
Lifting picture brightness, strengthens the shooting ability of the mobile phone low light level.The optical parametric of single flash lamp is
Changeless it is impossible to the change with environment to carry out the light filling of different modes.And surrounding ring
Border, in different time, different location and different scenes, can correspond to different-colour scope, example
As：Standard candle：1850K, tengsten lamp is 2760-2900K；Fluorescent lamp is 3000K；Dodge
