Detailed description of the invention
It is more fully described the exemplary embodiment of the disclosure below with reference to accompanying drawings.Although accompanying drawing shows the disclosure
Exemplary embodiment, it being understood, however, that may be realized in various forms the disclosure and should be by embodiments set forth here
Limited.On the contrary, it is provided that these embodiments are able to be best understood from the disclosure, and can be by the scope of the present disclosure
Complete conveys to those skilled in the art.
With reference to Fig. 1, it is shown that the step of the processing method embodiment of a kind of view data
Rapid flow chart, specifically may include steps of:
Step 101, obtains the raw image data of camera collection.
In implementing, the embodiment of the present invention can be applied in the terminal, such as, mobile phone, panel computer, individual
Personal digital assistant, wearable device (such as glasses, wrist-watch etc.) etc..
The operating system of these mobile terminals can include Android (Android), IOS, Windows Phone, Windows
Etc..
In embodiments of the present invention, photographic head camera can be configured in the terminal.
These photographic head can be only fitted to the front portion (also known as front-facing camera) of mobile terminal, it is also possible to is arranged in mobile whole
End back (also known as post-positioned pick-up head), additionally, the quantity of this photographic head can be single, can also be two or two with
On, such as dual camera, etc., this is not any limitation as by the embodiment of the present invention.
In one example, photographic head can include camera lens Lens, pedestal Holder, infrared filter IR, image sensing
The parts such as processor Sensor, circuit board.
Wherein, image sensing processor Sensor is a kind of semiconductor chip, and its surface includes hundreds of thousands to millions of
The photodiode not waited, when photodiode receives light irradiation, can produce electric charge.
Image sensing processor Sensor can convert light into the signal of telecommunication, then is turned by internal DA (digital-to-analogue conversion)
It is changed to digital signal, the imaging plane that plane is view data at image sensing processor Sensor place.
In actual applications, the optical imagery that scenery (SCENE) is generated by the camera lens Lens of photographic head projects image
On sensing processor Sensor surface, then turn to the signal of telecommunication, after A/D (analog digital conversion) changes, become digital picture letter
Number, by data image signal is compressed and is converted into specific image literary composition by digital signal processing chip DSP or code database
Part form, is located by the processor (Central Processing Unit, CPU) of data bus transmission to mobile terminal
Reason, then can show at the screen of mobile terminal.
Step 102, identifies colour of skin view data in described raw image data.
In embodiments of the present invention, colour of skin view data can be identified by Face Detection from raw image data.
So-called Face Detection, is to choose the process corresponding to human skin pixels in view data.
According to either with or without relating to imaging process, Face Detection can mark off the following two kinds type:
1, Face Detection based on statistics
The key step of Face Detection based on statistics includes color notation conversion space and skin color modeling.
Color space is selected inherently to select the most basic character representation of Face Detection.Skin color modeling is to know about the colour of skin
The computer representation known, generally sets up complexion model by training sample set and carries out Face Detection, can be by according to different application
Skin color modeling is divided into static and dynamic two classes.
Wherein, for color space, the colour of skin is quite concentrated in the distribution of color space, but can by illumination with ethnic group very
Big impact, is affected by intensity of illumination to reduce the colour of skin, and color space is generally converted into brightness and colourity classification certain from RGB
Individual color space, such as YCbCr or HSV, then abandon brightness.
For static skin color modeling, the sides such as skin color range, Gaussian density function estimation and statistics with histogram can be passed through
Formula sets up complexion model, the most corresponding thresholding of this three, parametrization and the method for imparametrization.
For dynamic skin color modeling, can by complexion model parameter is adjusted to adapt to certain width still image, or,
For sequence image, adapt to the image-forming condition mode such as over time and set up complexion model.
2, Face Detection based on physics
Under complicated lighting condition, in such as image, the colour of skin is in specular or shadow region, in order to from imaging mechanism on gram
Take illumination and image paid no attention to impact, when Face Detection, it is considered to the interaction of light and skin, it is considered to skin POP is special
Property, this Face Detection technology referred to as Face Detection based on physics considering electromagnetic radiation and the mutual physical action of skin.
In a kind of Face Detection mode based on physics, colour of skin inspection can be carried out by the physical model of skin reflex
Surveying, such as, dichromatic reflection model can simulate opaque non-uniform dielectric thing according to the reflection characteristic of non-uniform dielectric
Body reflection process, to carry out Face Detection.
In an example of the embodiment of the present invention, owing to taking pictures people, especially autodyning, face is composition
One of pith, therefore, it can carry out Face datection in raw image data, it is thus achieved that face image data, at this face
View data identifies colour of skin view data.
So-called Face datection, can refer to calibrate the positions and dimensions of face from view data.
In Android, it is provided that a method directly carrying out face detection on bitmap, the two API
(Application Programming Interface, application programming interface) is respectively
Android.media.FaceDetector and android.media.FaceDetector.Face.
Specifically, extend base class ImageView, become MyImageView, and carry out the bitmap comprising face detected
File is usually 565 forms, to ensure that API normally works.
The face being detected needs a confidence measure (confidence measure), and this measure is defined on
android.media.FaceDetector.Face.CONFIDENCE_THRESHOLD。
Wherein, FaceDetector object-instantiated can be called findFaces by setFace () simultaneously, and result is deposited
In faces, MyImageView is transferred at the midpoint of face.
It follows that add setDisplayPoints () method in MyImageView, it is used at the face being detected
Upper labelling renders.
And API returns the information that other are useful, such as, such as eyesDistance, pose can be returned simultaneously, and
Confidence, then can position the center of eyes by eyesDistance.
Certainly, above-mentioned Face Detection is intended only as example, when implementing the embodiment of the present invention, can set according to practical situation
Putting other Face Detection, this is not any limitation as by the embodiment of the present invention.It addition, in addition to above-mentioned Face Detection, art technology
Personnel can also use other Face Detection according to actual needs, and this is not any limitation as by the embodiment of the present invention.
Step 103, is normalized described colour of skin view data according to default target colour of skin color value, it is thus achieved that
Destination image data.
In implementing, if detecting and raw image data existing colour of skin view data, then can extract default
Target colour of skin color value, this target colour of skin color value can be system default, it is also possible to be user setup, and the present invention implements
This is not any limitation as by example.
As a example by RGB color, in target colour of skin color value, R (red) value is generally higher than G (green) value, and G (green) value is general
More than B (blue) value, such as (215,177,141), (249,217,204), (253,227,204) etc..
Be normalized with colour of skin view data by target colour of skin color value, can allow input colour of skin picture number
According to the colour of skin tend to, even up to target colour of skin color value, the colour of skin that output is stable, consistent.
In actual applications, Eigen Skin color image can be selected in colour of skin view data by certain selection rule
Data, are normalized Eigen Skin color view data according to default target colour of skin color value, it is thus achieved that target image number
According to.
For example, it is possible to select Eigen Skin color view data according to brightness and/or exposure, screen out some brightness irregularities,
The colour of skin view data of overexposure, retains brightness uniformity, does not has the colour of skin view data of overexposure.
Specifically, brightness and/or the exposure of colour of skin view data can be added up by modes such as statistics with histogram.
From colour of skin view data, choose brightness be less than, in default brightness section and/or exposure, the threshold exposure preset
View data, as Eigen Skin color view data.
Certainly, it is normalized except selected part colour of skin view data, it is also possible to whole colour of skin view data
Being normalized, this is not any limitation as by the embodiment of the present invention.
In one embodiment of the invention, step 103 can include following sub-step:
Sub-step S11, adds up the original colour of skin color value in described colour of skin view data；
In implementing, the pixel color value of each pixel in colour of skin view data can be obtained, such as rgb value, calculate
The meansigma methods of pixel color value, as original colour of skin color value.
Sub-step S12, uses described original colour of skin color value to calculate normalization coefficient with the target colour of skin color value preset；
In implementing, normalization coefficient can be calculated based on calculating target colour of skin color value, adjust original skin with this
Color color value.
In an example of the embodiment of the present invention, sub-step S12 can include following sub-step:
Sub-step S121, calculates the ratio between target colour of skin color value and the original colour of skin color value preset, it is thus achieved that face
The whole ratio of tone；
As a example by RGB color, it is assumed that target colour of skin color value is (Rsample, Gsample, Bsample), photographic head inputs
The original colour of skin color value of colour of skin view data be (Rinput, Ginput, Binput), then, it is (R that color adjusts ratioratio,
Gratio, Bratio):
Rratio=Rsample/Rinput
Gratio=Gsample/Ginput
Bratio=Bsample/Binput
Sub-step S122, is multiplied by adjustment ratio by the pixel color value of pixel each in colour of skin view data, it is thus achieved that pixel
Color value set.
Sub-step S123, chooses object pixel color value from pixel color value set.
In implementing, can be from pixel color value set, the pixel color value that selected value is maximum, as target
Pixel color value.
Certainly, in addition to the pixel color value of selected value maximum, it is also possible to choose other pixel color value as target
Pixel color value, this is not any limitation as by the embodiment of the present invention.
As a example by RGB color, it is assumed that adjustment ratio is (Rratio, Gratio, Bratio), then, by (Rratio, Gratio,
Bratio) carry out product with each pixel of colour of skin view data, obtain R(0,1,2,...,n), G(0,1,2,..,.n),
B(0,1,2,...,n), wherein n is integer.
Statistics R (0,1,2 ... n), G (0,1,2 ... n), B (0,1,2 ... maximum RGB in n)maxAs target picture
Element color value.
Sub-step S124, uses color to adjust ratio and described object pixel color value calculates normalization coefficient.
In implementing, the ratio between default color threshold and object pixel color value can be calculated, as picture
Element color-ratio, calculates color and adjusts the product between ratio and pixel color ratio, it is thus achieved that normalization coefficient.
As a example by RGB color, it is assumed that adjustment ratio is (Rratio, Gratio, Bratio), object pixel color value is
RGBmax, then normalization coefficient is:
Rratio*255/RGBmax
Gratio*255/RGBmax
Bratio*255/RGBmax
Sub-step S13, is adjusted with described normalization coefficient, it is thus achieved that return on the basis of described original colour of skin color value
One changes colour of skin color value；
Sub-step S14, adjusts described colour of skin view data with described normalization colour of skin color value, it is thus achieved that target image number
According to.
In embodiments of the present invention, can be adjusted according to normalization coefficient on the basis of original colour of skin color value,
Output normalization colour of skin color value.
As a example by RGB color, it is assumed that original colour of skin color value is (Rinput, Ginput, Binput), normalization coefficient be
(Rratio*255/RGBmax, Gratio*255/RGBmax, Bratio*255/RGBmax), then the normalization colour of skin color value exported
(Rfinal, Gfinal, Bfinal) it is:
Rfinal=Rinput*Rratio*255/RGBmax；
Gfinal=Ginput*Gratio*255/RGBmax；
Bfinal=Binput*Bratio*255/RGBmax；
At present, in the camera module of mobile terminal, can AEC (Automatic Exposure Control, automatically
Spectrum assignment) and AWB (Automatic white balance, AWB) stable after, indexed by the exposure of AEC
(index) value, and the color temperature value (CCT) of AWB output, remove the color rendition (color that dynamic calculation current scene should use
And saturation (color enhancement) parameter correction).
The most just create problem, such as, in different angles, different exposures, and different AWB output, even if AWB
Difference little, the color rendition of final utilization and saturation parameters can be inconsistent, and the image colour of skin causing out is inconsistent,
Even same person is tested, in different angles, in the case of different light sources, colour of skin difference is the biggest.
Meanwhile, the screen of the mobile terminal of different-colour (warm colour screen, cool colour screen etc.) shows that form is each especially
Different.
Therefore, Consumer's Experience is the most bad, the most existing adjustable parameter, and adjustment method, and debugging cycle is the longest, and
And it is extremely difficult to expected effect.
The scheme that the present invention provides, user can use mobile terminal, obtains the raw image data of camera collection, from
Raw image data identifies colour of skin view data, according to default target colour of skin color value, colour of skin view data is carried out normalizing
Change processes, it is thus achieved that destination image data so that the colour of skin of input can tend to, be even up to the target colour of skin, solves the colour of skin and is subject to
The control of image procossing, stability in the large is poor, causes the colour of skin under circumstances, shows different problem, exports stable, consistent
The colour of skin, meanwhile, shorten image procossing debugging cycle.
With reference to Fig. 2, it is shown that the processing method embodiment of another kind of according to an embodiment of the invention view data
Flow chart of steps, specifically may include steps of:
Step 201, obtains the raw image data of camera collection.
Step 202, carries out image procossing to described raw image data.
In embodiments of the present invention, if camera collection is to view data, then can carry out ISP (Image Signal
Processing, image signal processing) process.
Wherein, image procossing includes following at least one:
1, auto-exposure control
Exposure is used to calculate the physical quantity of the luminous flux size arriving camera from scenery.Imageing sensor is only just obtaining
True exposure, just can obtain high-quality photo.Over-exposed, image seems the brightest under-exposure, then image seems too
Secretly.The size of the luminous flux arriving sensor is mainly determined by two aspect factors: the length of time of exposure and the size of aperture.
Utilize aperture to carry out automatic exposure, mainly control aperture size according to captured scene so that light-inletting quantity is tieed up
Hold within the specific limits.The cost being exposed controlling by aperture is higher.
Auto-exposure control algorithmic method generally has two kinds:
A kind of method is to use with reference to brightness value, and image uniform is divided into the subimage of many, each piece of subimage bright
Degree is used to arrange with reference to brightness value, and this brightness value can be obtained by the speed arranging shutter.
Another method is, is exposed by the relation between brightness and the exposure value under research different illumination conditions
Photocontrol.
2, blank level adjustment
White balance is it can be appreciated that under the conditions of any colour temperature, the reference white captured by photographic head is through the tune of oversampling circuit
Whole, remain as white after being allowed to imaging.
AWB be based on the assumption that the meansigma methods of the color of scene fall specific at one in the range of, if measured
Deviateing this scope to result, then adjust corresponding parameter, correction is until its average falls into appointment scope.This processing procedure is potentially based on
Yuv space, it is also possible to carry out based on rgb space.For Sensor, common processing mode is to be increased by correction R/B
Benefit so that UV value falls in the range of an appointment.Thus realize AWB.
3, color rendition processes
The human eye identification to color, is, based on human eye, light is existed three kinds of different sensing units, different sensing lists
There is the principle of different response curves in unit to the light of different-waveband, is obtained the perception of color by the synthesis of brain.In general,
The concept by RGB three primary colours that can be popular understands decomposition and the synthesis of color.
In theory, if human eye and the sensor (sensor) response to the coloured light of spectrum, embodiment spectrally
Words, the substantially response to three coloured light, will not make a difference each other, there is no so-called cross effect.But, practical situation
The most preferable, the trichroism induction system of the human eye response condition to spectrum, is that the response of RGB is not to be completely independent
's.
On each component of RGB the most devious to the response of spectrum with human eye, be certainly accomplished by it is corrected.
The most just in cross effect, the response intensity of each to color equally component is also required to correction, it is common practice to by one
Color is once corrected by color correction matrix.
The computing of this colour correction is typically integrated by sensor module or rear end ISP and completes, and posts by amendment is relevant
Storage obtains correct correction result.Wherein, also it is the conversion by a 3*3 due to color space conversion from RGB to YUV
Matrix realizes, so sometimes the two matrix can combine during ISP processes, is transported by a matrix
Calculate and operated the correction of color and the conversion of color space.
4, color enhancement processes
In implementing, the color representation of view data can be strengthened by modes such as regulation saturations.
So-called saturation, refer to is the purity of color in fact, and purity is the highest, shows the distinctest, and purity is relatively low, and performance is then
Dulller.
Owing to each pixel of liquid crystal is made up of red, green, blue (RGB) sub-pixel, backlight is by relying on RGB picture after liquid crystal molecule
Element is combined into random color light.If RGB three primary colors is the most bright-coloured, then the color gamut that display can represent is the widest.As
Really display three primary colors is the most bright-coloured, and the color gamut that this display can show is the most narrow, because it cannot show ratio
Three primary colors more chromatic colour.Therefore, the method improving color saturation is to improve backlight spectra and trichromatic purity.
5, denoising
In the collection and transmission of view data, image data quality be often subject to various effect of noise and under
Fall.
Such as, the sound pollution when imageing sensor obtains view data, owing to data volume at this time is less, noise
Directly affect interpolation algorithm below, and make the details of image to embody, both affected the interpolation of image, also affected people's
Visual experience.
Therefore in image procossing, the removal of noise is a very important link.
The mode of denoising, it is common that the point of surrounding taking average to substitute original value, this way does not increase
Quantity of information, is similar to a fuzzy algorithmic approach.
When detection, comprehensively can judge noise as standard by brightness and color, use interpolation algorithm to compensate,
For the bad point that sensor is intrinsic, noise, the mode of shielding is used to abandon its data etc..
Certainly, above-mentioned image procossing is intended only as example, when implementing the embodiment of the present invention, can set according to practical situation
Putting other image procossing, as stroboscopic suppresses, this is not any limitation as by the embodiment of the present invention.It addition, in addition to above-mentioned image procossing,
Those skilled in the art can also use other image procossing according to actual needs, and this is not limited by the embodiment of the present invention
System.
Step 203, identifies colour of skin view data in described raw image data.
Step 204, is normalized described colour of skin view data according to default target colour of skin color value, it is thus achieved that
Destination image data.
In embodiments of the present invention, colour of skin view data can be identified from the raw image data after image procossing,
And according to default target colour of skin color value, colour of skin view data after image procossing is normalized, it is thus achieved that target figure
As data.
For embodiment of the method, in order to be briefly described, therefore it is all expressed as a series of combination of actions, but this area
Technical staff should know, the embodiment of the present invention is not limited by described sequence of movement, because implementing according to the present invention
Example, some step can use other orders or carry out simultaneously.Secondly, those skilled in the art also should know, description
