Description
Technical field
The present invention relates to mobile phone photograph field, in particular to a kind of proactive light compensating lamp brightness control method of mobile phone and mobile phone
The control device of proactive light compensating lamp.
Background technology
The appearance of mobile phone changes the life style of people.Current phone industry quickly develops, diversified
Function enters the visual field of people, it has been not only the communication tool that can make a phone call to send short messages, and requirement of the people to him is more next
It is higher.Instantly for mobile phone photograph into mainstream, people like that sharing the photo of oneself in social networks shows life.For liking
It is beautiful for the people to take pictures, it is a thing that cannot at all put up with.More and more fans that take pictures are keen to entertaining and take pictures,
To show different style, the individual character of oneself is embodied.
During photography, it can sometimes run into and of photography the very dim situation of main body ambient light, at this time
The luminosity of main body must be improved by fill-in light, and most stable and most convenient fill-in light is probably exactly flash lamp.Mostly
Several flash lamps is all very light and handy, and price is not also expensive, and luminous power is also very powerful, and almost can be complete using flash lamp
The direction of the full property for grasping light, light quantity and light.This artificial light sources can also substitute the natural light at scene completely, these controls
Light freely is the optimal guarantee of Originality Representation.And flash lamp is with other light sources maximum difference, flash lamp is that moment is bright
The light source to go out, fluorescent lifetime is very brief, and luminosity is strong.
Flash lamp is the electric discharge in the pipe for being filled with xenon (Xe) using high-tension current, and produces very brief strong sudden strain of a muscle
Light, and because it is Discharge illuminating, without filament, therefore can Reusability more than ten thousand times.And the performance of flash lamp, by initial manual control
Adjust, develop into the automatic flash light of sensor photosensitive, more progressive to be exposed to TTL automatic flashs, development is extremely quick.Plus lamp
Head swing, split sensor, zoom flash, variable output power, LED and sound wave show, son-mother lamp, colour filter, reflector,
The various annexes such as charger, are even more that species is various, too plenty for the eye to take it all in.Briefly, all with small portable, system is complete, and equipment is more
Member turns to master.
And flash lamp can be divided into two kinds of built-in flash and circumscribed flash lamp because of its connection relation with camera,
Magazine built-in flash is typically either built into due to being directly on strong illumination to reference object, is produced sometimes
Ugly shade, so when circumscribed flash lamp is preferred, in addition, it is more that circumscribed flash lamp can more provide cameraman
Manually control light source selection project, such as can unrestricted choice flash lamp intensity, size, number and frequency, considerably increase
The photography scope of application, and shade strong caused by built-in flash and blood-shot eye illness can be avoided, therefore be the camera work of specialty
Person generally uses.
As camera field, the appearance of first mobile phone with flash lamp, is wanted on mobile phone in itself than camera
A little later.It can examine on the market, first is Siemens S57 for the mobile phone that camera has matched somebody with somebody flash lamp, its Time To Market is 2002
Year December, at that time the publicity point of this mobile phone just cry " glittering bat ", problem be the camera of this mobile phone be it is independent outside
If mobile phone is in itself without camera, on the camera module that flash lamp is also matched somebody with somebody outside.It is than first mobile phone with camera in history
The appearance evening of Sharp J-SH04 is more than 2 years.And the first really mobile phone of built-in flash can less have been examined, it is expected to be at that time time
Certain Japan's mobile phone that ground is bloomed, the more famous mobile phone with flash lamp in 2003 are Sharp GX20, NEC N700 etc..
As mobile phone increasingly focuses on image quality, this seems also to do and must turn out a prestigious institution LED light supplement lamp industry for 2 years, compares
Famous is the LUXEON Flash series of products of Philips Lumileds, its official website lists 4 serial different products,
From low side to high-end essential difference in terms of the main just brightness in offer, the LXCL-LW07 of wherein most significant end has been able to carry
For the brightness of 500lm.This has also shown, and is equally mobile phone, and it is poor that the LED light supplement lamp that the product that difference positions is matched somebody with somebody also exists
Not.150-300mA, that is, drivable LED light supplement lamp is dodged from super low-end is false, " high-end " scheme to 2000mA all has, it appears that is intended to
For the mobile phone products of different resolution scheme；Such as cameras more than 10,000,000 pixels, LED light supplement lamp manufacturer think
1.1 μm of Pixel Dimensions sensitivity is very poor, so needing double LED schemes of at least two 1A electric currents driving to provide higher brightness.
So if you are with low-end mobile phone, may LED light supplement lamp all than other poor one section.And flagship machine is tended to using double
LED light supplement lamp scheme (is commonly considered as before and after 2007, and appearance opportunity of the xenon flash lamp on mobile phone is similar).Two
The light filling efficiency of LED lamp is certainly better than one, and is accessed in optical design using double light sources, imaging region interior energy
More preferable edge uniformity.But in fact, a LED lamp is simply divided into two (such as two by many double LED light supplement lamps
The LED light of 500mA is double at the same time to dodge, the also big difference of nothing compared with the LED light of a mainstream 1000mA), even two
The LED light supplement lamp of 1000mA, compared to the light compensating lamp of a 1000mA, luminance raising probably also only has 30%.
In short, with the improvement of image sensor and optical component, the photograph of high quality selects appropriate benefit in order to obtain
