State light supply apparatus, certainly it can be appreciated that described light supply apparatus may include but be not limited to lighting source, and should
Light supply apparatus can be one or more.
It should be noted that for need light modulation light supply apparatus have multiple when, also can be according to one
Fixed screening conditions therefrom determine that the influence degree corresponding to the image to described preview of taking pictures is bigger
Light supply apparatus, as the light supply apparatus needing to respond this light modulation and driving signal.Wherein, described screening bar
Part can be arranged the most flexibly, and this is not limiting as by the application.Such as, described screening conditions
Can determine according to the command information that terminal receives, the command information as inputted according to user determines, by
This, meet diversified user's request.The most such as: described screening conditions can be according to this light supply apparatus institute
The ray relative sent in the degrees of offset of the center of the environment corresponding to the image of described preview of taking pictures,
As deviation angle exceeded the light supply apparatus that the light supply apparatus of a certain setting value dims as needs, thus carry
Light efficiency to a high-profile.
Accordingly, in an embodiment of this programme, each light supply apparatus can be arranged a unique mark
Know code, to distinguish different light supply apparatuses.When terminal by default transmission channel at least one light source
When device sends this light modulation driving signal, transmission of enclosing has the exclusive identification code corresponding to current light source device.
When all of light supply apparatus receives this light modulation driving signal, this exclusive identification code can be received in the lump, and
Judge that this exclusive identification code exclusive identification code whether with this light supply apparatus matches, only at two identification codes
During coupling, just signal is driven to perform corresponding Dimming operation in response to this light modulation；Otherwise, light supply apparatus is lost
Abandon received light modulation and drive signal, do not do light modulation and process.
Wherein, any during optical parametric information described in this programme can be contrast, brightness and colour temperature
One or more.It is that contrast, brightness and colour temperature determine correspondence separately below to optical parametric information
Light modulation drives signal, illustrates respectively.
1, in an embodiment of this programme, described optical parametric information is contrast, and terminal is according to working as
The contrast of front environment determines that the light modulation of its correspondence drives signal, so that the contrast of this current environment
Reach goal-selling scope.Such as, sensor as aforementioned detects residing for the image that institute's preview of currently taking pictures is found a view
The contrast at least one edge of environment, if described contrast is beyond the reference contrast range preset,
Terminal sends light modulation to the light supply apparatus determined and drives signal, to indicate described light supply apparatus according to this light modulation
Signal is driven to carry out the adjustment of brightness adjustment or contrast.Wherein, described reference contrast range can be pre-
First determining, this is not limiting as by this programme.
Contrast deficiency can affect the focusing of photographing device, and the program can be applied but be not limited at the overall low light level
Environment, in the scene that the image found a view such as institute's preview of currently taking pictures is substantially under-exposed, is adjusted by corresponding
The brightness of the whole light supply apparatus bigger on present image impact or contrast, it is achieved to institute's preview of currently taking pictures
The adjustment of the picture contrast found a view, is thus conducive to improving focusing speed when terminal is taken pictures, improves and clap
According to effect.
2, in an exemplary embodiment of this programme, described optical parametric information can be brightness, eventually
According to the brightness of current environment, end determines that the light modulation of its correspondence drives signal.Accordingly, aforesaid detector
Detect the luminance mean value of the image local environment that institute's preview of currently taking pictures is found a view, if described luminance mean value surpasses
Going out default reference brightness scope, terminal sends light modulation to the light supply apparatus determined and drives signal.Wherein,
Determine that according to present intensity average the mode of the light modulation driving signal of its correspondence can be the most flexible
Arranging, this is not limiting as by the application.Such as, can come really according to the brightness regulation instruction that terminal receives
Fixed, the brightness regulation instruction as inputted according to user determines that the light modulation corresponding to this instruction drives signal, by
This, meet diversified user's request.
This embodiment can apply but taking pictures in overall low light environment of being not limited to or described in take pictures find a view pre-
The image overall brightness deviation look at is relatively big, the scene that the image of preview of finding a view as taken pictures is the darkest or the brightest
In, the brightness of the light supply apparatus bigger on the impact of present image local environment is adjusted by specific aim, it is achieved
Luminance compensation to current photo environment.

Light unit, green luminescence unit and blue light emitting unit, accordingly, detect according to sensor as aforementioned
Optical parametric information can respectively obtain HONGGUANG and drive signal, green glow to drive signal and blu-ray drives signal,
HONGGUANG is utilized to drive the driving electric current of red light-emitting unit described in Signal Regulation, green glow to drive signal for adjusting
Drive electric current, the blu-ray drives signal of joint green luminescence unit are used for regulating the driving electricity of blue light emitting unit
Stream, so that the light that red light-emitting unit, green luminescence unit and blue light emitting unit are sent is through joining
Colour temperature after Bi reaches aim colour temperature value.
It can be appreciated that use the trichroism mixed light that carries out of RGB can improve the accuracy that this programme colour temperature controls, its
In, the effect that red green two color (RG) mixes is mainly used in realizing low colour temperature, and the effect of blue (B) is mainly used
In promoting high color temperature.More than being merely illustrative, the colour temperature regulation part of this programme can also use it
His LED particle realizes, and this is not limited by this programme.
Embodiment described in the program can apply but be not limited to colder at light or partially warm environment are taken pictures or
The find a view image local colour temperature deviation of institute's preview of currently taking pictures described in person is relatively big, and as included, taking pictures of face takes
In the scene that in the image of scape institute preview, the colour of skin of face is substantially uneven, by adjusting current figure targetedly
As local environment affects the colour temperature of bigger light supply apparatus, it is achieved the luminance compensation to current photo environment.
It should be noted that the present embodiment is starting the application of taking pictures of described terminal, after entering shooting interface,
