With reference to Fig. 2, a kind of flow chart of the processing method of image color cast of the embodiment of the present invention two is shown, specifically can be with
Include the following steps：
Step 201, the pending image is obtained.
In embodiments of the present invention, when user needs to be adjusted the colour cast in an image, it is possible to specify need
The image of processing, then mobile terminal can get the pending image.
Step 202, when carrying out U.S. face processing to the pending image, the skin area of the pending image is identified
And background area.
In embodiments of the present invention, determine to treat by image recognition when carrying out pending image U.S. face processing at present
Handle the skin area in image and background area.
Under normal conditions, the color of the color of skin area and periphery background is there are larger difference, by color contrast,
It can determine that the elementary contour of skin area, then by carrying out further skin color model to the pixel of outline perimeter, you can it is accurate
Determine the skin area in pending image, the region outside skin area is background area.
After the skin area of pending image is determined, by carrying out colour adjustment to skin area, white print is added
Layer adjusts transparency to reach the effect of U.S. face.Generally, in the case where light is good, skin area is partially red, so can lead
Cause red channel in character image partially bright so that the details component that red channel retains is less, and in contrast, green channel retains
More details, therefore, by carrying out Fuzzy Processing to green channel, adjust transparency, then the image that U.S. face is handled is located with waiting
Image blend is managed, obtains U.S. face effect image.
After U.S. face processing is carried out to pending image, the skin area and/or background area in U.S. face effect image are judged
Also whether there are colour cast in domain.Certainly, the embodiment of the present invention can also be directed to the image progress color correction for not carrying out U.S. face processing.
Step 203, for the skin area, whether the corresponding RGB color value of the skin area is detected beyond default model
Enclose.
In embodiments of the present invention, by gathering multiple character images, the corresponding RGB of skin area in character image is obtained
Colour, according to the RGB color value of multiple skin areas of acquisition, so that it is determined that going out the preset range of skin area.
For the skin area in U.S. face effect image, the corresponding RGB color of skin area in U.S. face effect image is detected
Whether value exceeds preset range, when the corresponding RGB color value of the skin area in U.S. face effect image exceeds preset range, judges
Skin area colour cast, contrasts the RGB color value of skin area and the RGB color value of preset range, when some color of skin area
When numerical value exceeds more, determine that the color of skin area is inclined to the color, that is, be inclined to color of object.Wherein, RGB represents three respectively
Red, green and blueness in primary colors.
Step 204, for the background area, according to the RGB histograms of the background area, the background area is determined
Color whether be inclined to color of object.
In embodiments of the present invention, carry out analysis to the RGB histograms of normal picture and colour cast image to find, if schemed
In the RGB histograms of picture, Colour is single peak, or concentration is compared in distribution, and when colourity average value is larger, is generally all deposited
In colour cast, and colourity average value is bigger, and colour cast is more serious.According to the flat of the average brightness value of tri- passages of RGB and whole image
Equal brightness value is compared, when the average brightness value of single Color Channel is more than the average brightness value of whole image, then entirely
The color of image is inclined to the corresponding color of the single Color Channel.
Therefore, for the background area in U.S. face effect image, the RGB histograms of background area are obtained, to background area
RGB histograms analyzed, determine whether the color of background area is inclined to color of object.
Step 205, when the color of the skin area and/or background area is inclined to color of object, the target is obtained
The RGB color value of color.
In embodiments of the present invention, when the color of skin area and/or background area is inclined to color of object, by searching for
RGB color value table, obtains the RGB color value of color of object.
For example, when the color of skin area is inclined to color of object, and color of object is gilvous, corresponding RGB color value
For R255G255B0.
Step 206, R colours, G colours and B colours are individually subtracted by setting value, it is corresponding mutually obtains the color of object
Complementary color.
In embodiments of the present invention, in order to reduce the aberration of pending image, it is necessary to calculate the complementary colours of color of object, lead to
Cross setting value and R colours, G colours and B colours is individually subtracted, you can the RGB color value of the corresponding complementary colours of color of object is obtained, according to
The RGB color value being calculated determines corresponding complementary colours.
Under 8 bit port patterns, setting value 255, under 16 bit port patterns, setting value 65535.Generally, usually
Using 8 bit port patterns, which can show 256 × 256 × 256=1677, ten thousand colors, discernmible beyond human eye
Color sum, therefore, than the passage rank of 8 bit port pattern highers, does not have any difference for human eye.
For example, for 8 bit port patterns, when color of object is gilvous, by calculating R (255-255) G (255-255) B
(255-0), the RGB numerical value for obtaining corresponding complementary color are R0G0B255, its corresponding complementary colours is pure blue.
Step 207, the colour cast ratio of color of object is inclined to according to the color of the skin area and/or background area, really
The number scope of the pixel of fixed complementary colours corresponding with the color of object.
In embodiments of the present invention, the colour cast ratio of color of object is inclined to according to the color of skin area and/or background area
Example, determines the number scope of the pixel of the complementary colours added in skin area and/or background area.
Wherein, for skin area, the numerical values recited of preset range can be exceeded according to color of object, determines skin area
Color is inclined to the colour cast ratio of color of object；For background area, according to the average brightness of the corresponding Color Channel of color of object
Value, the size of the difference between the average brightness value of whole image, determines that the color of background area is inclined to the colour cast of color of object
Ratio.
Changes in temperature can be set to adjust litter, the centre position correspondence that changes in temperature adjust litter is unbiased color image；Changes in temperature are adjusted
When litter is adjusted up, the pattern colour tuningout after alignment processing warms up；When changes in temperature adjusting litter is adjusted downwards, after alignment processing
Picture tone is colder.Wherein, skin area and background area can be directed to, sets a changes in temperature to adjust litter respectively.
If changes in temperature are adjusted litter adjusting to centre position, the standard number of the pixel of complementary colours is determined；If will be cold
When warm color tone section litter is adjusted to highest point, the first critical number of the pixel of complementary colours is determined；If changes in temperature are adjusted into litter tune
When saving to lowest point, the second critical number of the pixel of complementary colours is determined.Between first critical number and the first critical number
Region i.e. complementary colours pixel number scope.
If complementary colours is cool tone, the first critical number of the pixel of complementary colours is less than standard number so that processing
Pattern colour tuningout afterwards warms up；If complementary colours is warm tones, the first critical number of the pixel of complementary colours is more than standard number,
So that the pattern colour tuningout after processing warms up.Wherein, cool tone generally comprises green, blueness etc., and warm tones generally comprises red, yellow
Color etc..
For example, when complementary colours is pure blue, the colour cast ratio of color of object is inclined to according to the color of skin area, is determined
The number scope M1 to Mn of the pixel of pure blue.
Step 208, the position of litter is adjusted based on current changes in temperature, the complementation of corresponding number is chosen in the range of the number
The pixel of color.
In embodiments of the present invention, skin area and/or background area are clicked on, adjustment of cold/warm adjusts the position of litter,
The pixel of the complementary colours of corresponding number is chosen in the range of number.
When only having the color of skin area to be inclined to color of object in pending image, user clicks on skin area, adjusts
The changes in temperature of skin area adjust the position of litter, choose the pixel of the complementary colours of corresponding number；When in pending image only
During the color deviation color of object of background area, user clicks on background area, and the changes in temperature for adjusting background area adjust the position of litter
Put, choose the pixel of the complementary colours of corresponding number；When the color of skin area and background area is inclined in pending image
During color of object, user clicks on skin area and background area, the corresponding changes in temperature adjusting cunning for adjusting skin area and background area
The position of pole, chooses the pixel of the complementary colours of corresponding number.
For example, when the color of skin area is inclined to color of object, the complementary colours of color of object is pure blue, according to user's tune
The changes in temperature of section adjust the position of litter, and the pixel of Ma pure blue is chosen in number scope M1 to Mn.
Step 209, the pixel of the complementary colours of the corresponding number is even added to the skin area and/or background
