Description
Technical field
The present invention relates to portable electronic device fields, in particular to the shooting field of portable electronic device.
Background technique
Mobile photographing device (such as the portable photographics such as mobile phone, tablet computer device) benefit of taking pictures of the market overwhelming majority at present
Light configuration be LED light filling, and LED light filling insufficient light or take pictures apart from it is distant when, since light luminance is limited very
Difficulty reaches ideal light filling effect.
Xenon flash lamp is also known as high-intensity discharge formula Gas lamp, can be realized the flash of light far more than LED flash brightness,
And there is outstanding daylight reducing power.The photo of high-quality can be preferably shot using xenon flash lamp, especially
It is taking pictures apart from the weaker lower use of distant or light, effect becomes apparent.Therefore some professions camera installation (such as singly
Lens reflex camera) there is outfit xenon flash lamp.
But existing xenon flash lamp volume is larger, thickness is thicker, does not meet becoming for present mobile terminal slimming
Gesture.Moreover, the considerations of for cost and slimming, it is COMS sensor that present mobile terminal, which mostly uses greatly photographic film, but
The time that xenon flash lamp is lighted is very short, and for about 40 microseconds to 2 milliseconds, shorter than general cmos sensor collects light from the beginning to the end
The time of line, if do not have to mechanical shutter, exposure when will a part be it is bright, a part or secretly.And make
With mechanical shutter, all pixels are first allowed successively to be opened when shutter close, then mechanical shutter is opened, and pixel exposes simultaneously
Light, then mechanical shutter is closed, and pixel is simultaneously stopped exposure, then successively closes.So xenon flash lamp is more suitable for machinery
Shutter, but be equipped with mechanical shutter and can make a big impact to mobile phone thickness.
In order to can be used xenon flash lamp, improves taking pictures for mobile photographing device and effect and do not increase mobile photographing device
Thickness, it is existing to occur by the way of external xenon flash lamp, such as Co., Ltd, ZTE Corporation, Shenzhen is (hereinafter referred to as
ZTE Corporation) on June 27th, 2013 apply and disclosed on December 11st, 2013 China No. 201320376363.6 it is practical
New patent just discloses a kind of external xenon flash lamp and corresponding camera system.
Technical solution disclosed by No. 201320376363.6 utility model patents of the applicant to ZTE Corporation is grown
The analysis and experiment of time finds that it is unable to reach good shooting effect, since the flash time of xenon flash lamp is very short (big
About 40 microseconds are to 2 milliseconds), it can not accomplish that mobile photographing device camera is taken pictures and xenon flash lamp flash synchronization substantially.
Summary of the invention
In view of this, the main purpose of the present invention is to provide a kind of camera system, a kind of xenon flasher, to improve shooting
Effect.
