The following detailed description of the realization method of the embodiment of the present invention.
Fig. 4 is the flow chart of the image processing method of the embodiment of the present invention, as shown in figure 4, the flow can include：
Step 401：Obtain the first image data comprising facial image using camera shooting；
In practical applications, when the processor of terminal receives the shooting instruction of user, control camera is to working as front court
Scape is shot.
Here, for how to judge whether comprising facial image in a kind of example, obtaining to scheme in image data
As after data, being detected using face recognition algorithms to image data, and then whether judge in image data comprising face figure
Picture；In another example, it can receive instruction input by user before using the shooting of the camera of terminal using terminal and believe
Breath when the current image to be captured of instruction information instruction input by user includes facial image, determines the use of camera shooting
Image data include facial image.
Step 402：Automatic white balance processing is carried out to described first image data, obtains the second image data；
It is understood that human visual system has the characteristics that color constancy, therefore the mankind can to the observation of things
Not influenced by light source colour.But imaging sensor in itself and without this color constancy the characteristics of, therefore,
The image taken under different light can be influenced by light source colour and be changed.Such as it is clapped under bright day
The image taken the photograph may be partially blue, and the object color taken under candle light can be partially red.Therefore, in order to eliminate light source colour for
The influence of imaging sensor imaging, automatic white balance function is exactly to simulate the color constancy feature of human visual system to disappear
Except influence of the light source colour to image.
In actual implementation, terminal can store the optimization automatic white balance Adjusted Option for various universal light sources；
The camera of terminal can detect the color of subject automatically according to the light conditions by its camera lens and white balance sensor
Temperature value judges imaging conditions with this, and immediate tone is selected to set, and white balance is transferred to suitable position automatically.
Step 403：The human face region of second image data is determined, by the RGB of each pixel of the human face region
Component is converted to YUV components.
Illustratively, for the second image data, the face that Face datection algorithm determines the second image data may be used
Region.
Face datection algorithm is mainly used for the pretreatment of recognition of face in practice, i.e., accurate calibration goes out face in the picture
Position and size.The pattern feature very abundant included in facial image, as histogram feature, color characteristic, template characteristic,
Structure feature and Haar features etc..Face datection is exactly that information useful among these is picked out, and is realized using these features
Face datection；Illustratively, method for detecting human face is based on features above using Adaboost learning algorithms, and Adaboost algorithm is
A kind of method for classifying, it is combined some weaker sorting techniques, is combined into new very strong sorting technique.
It is understood that when carrying out image procossing, the RGB color that can obtain the pixel of image data first is empty
Between each component, here, each component of RGB color includes R component, B component and G components.
It, can be by the RGB face of the pixel of image data in order to realize the coloration adjustment to image in the embodiment of the present invention
Each component of the colour space is converted to each component of YUV color spaces；Each component of YUV color spaces includes Y-component, U components and V
Component；Wherein, Y-component is luminance component；U components and V component are chromatic component, for describing image color and saturation degree.
Illustratively, the transformational relation of RGB color to YUV color spaces can be illustrated by the following formula：
Y=0.299*R+0.587*G+0.114*B

Value, the value of U components and the value of V component of the Y-component of YUV color spaces are represented respectively.
Step 404：For second image data, according to the coloration method of adjustment of preset human face region, to described
Chromatic component in the YUV components of each pixel of human face region is adjusted.
Illustratively, the coloration method of adjustment of preset human face region can include：
Pre-set the value range of the chromatic component of the pixel of human face region；When the face of second image data
When chromatic component in the YUV components of the pixel in region is in the value range of preset chromatic component, described the is kept
Chromatic component in the YUV components of the pixel of the human face region of two image datas is constant；As the people of second image data
When chromatic component in the YUV components of the pixel in face region is not in the value range of preset chromatic component, institute is adjusted
The chromatic component in the YUV components of the pixel of the human face region of the second image data is stated, makes the second image data after adjustment
Human face region pixel YUV components in chromatic component be in the value range of preset chromatic component.
Here, the chromatic component of above-mentioned record can include at least one of following：U components, V component.
It, can be with terminal user in advance by the Y-component of the YUV components of the pixel of human face region and U points in actual implementation
The value range of amount is input in terminal；Fig. 5 is an interface schematic diagram of the terminal of the embodiment of the present invention, as shown in figure 5, eventually
End is shown " value range that please input U components and V component ", and shows four input frames, is respectively used to input U components most
Big value and minimum value and the maximum value and minimum value of V component；After user inputs the value range of U components and V component, click
Confirming button, can with when terminal know human face region pixel chromatic component value range.
Optionally, can not occur the chromatic component in the YUV components of the history image data of colour cast according to human face region,
The value range of the chromatic component of the pixel of human face region is set；When implementing, can history image be judged by terminal user
Whether the human face region of data there is colour cast.
It should be noted that in the image processing method of the existing image data for camera shooting, in addition to certainly
Outside dynamic white balance processing and color correction, can also include resolution chart, black-level correction, camera lens shadow correction, bad point correction,
Green balance, removal noise, color interpolation, sharpening and etc.；In the embodiment of the present invention, for automatic white balance processing and color school
It is just illustrated, resolution chart, black-level correction, camera lens shade school can also be included by being not intended to limit in image processing process
Just, bad point correction, it is green balance, removal noise, color interpolation, sharpen and etc..
As can be seen that the second image data includes human face region and non-face region, in the embodiment of the present invention, for face
Region is adjusted using the coloration method of adjustment of preset human face region；Since the coloration method of adjustment of human face region can be with
It is configured according to actual needs, in this way, can be to avoid when carrying out coloration adjustment, the human face region of image data occurs partially
Color.
