Referring to Fig. 1, Fig. 1 is the schematic flow sheet of image processing method provided in an embodiment of the present invention.Specifically, should
Method includes：
In step S101, the sensitivity under terminal current environment is obtained.
It is understood that the sensitivity refers to ISO sensitivity, the ISO sensitivity is that the sensitivity to light is represented with numeral
Degree.ISO sensitivity is higher, represents stronger to the susceptibility of light.Therefore, high ISO sensitivity is adapted to shoot low illumination and motion
Object.
Further, when terminal is in image acquisition modality, it can be automatically adjusted according to the light intensity under current environment
The ISO sensitivity of terminal, when light intensity is stronger, the value of ISO sensitivity is smaller；When light intensity is weaker, the value of ISO sensitivity
It is bigger.Such as, when terminal is in outdoor, light intensity is stronger, and the value of ISO sensitivity is generally 100 or so.When terminal is in
When indoor, light intensity weakens, and the value of ISO sensitivity can become big, and typically nearly 500.
In one embodiment, current environment light can be gathered by the cam device in terminal, by IMAQ
Sensor draws current light intensity according to ambient light before deserving, then determines that the corresponding ISO of current light intensity feels
Luminosity.
In step s 102, corresponding blue sky tone range is determined based on sensitivity.
It should be noted that the tone is measured with angle, span is 0 degree to 360 degree, by counterclockwise since red
Direction calculating, red is 0 degree, and green is 120 degree, and blueness is 240 degree.Their complementary color is：Yellow is 60 degree, and cyan is 180
Degree, magenta is 300 degree.Current blue sky optimization of region method is one region of simple division, if the pixel on image

Domain, when the hue angle of the pixel on image falls into the region, is then determined as blue sky pixel.
In one embodiment, when the value for determining current ISO sensitivity, which is no more than, presets photosensitive threshold value, illustrate to work as
The image shot under preceding scene is likely to occur blue sky part, can draw blue sky tone range according to default formula.
Such as, blue sky tone range can be represented with H, blue sky tone range H ∈ [α1,α2]；
The α1=210-10 × [1- | ISO-100 | ÷ ISO]；
The α 2=210+10 × [1- | ISO-100 | ÷ ISO].
Wherein, this 210 be optimized parameter, can be adjusted according to actual conditions, the ISO be ISO sensitivity value.
It can be seen from formula when terminal is in interior, ISO sensitivity is about 100 or so, blue sky tone range H

In step S104, according to blue sky tone range tone corresponding with the pixel in image, pixel is satisfied
Handled with degree.
Wherein, when the angle for the tone for having pixel in image is fallen into the blue sky tone range, then by the tone
The pixel that angle falls into the blue sky tone range confirms as blue sky pixel.Then the saturation degree to blue sky pixel carries out phase
The regulation answered, to reach the purpose of blue sky optimization.
In one embodiment, when determining blue sky pixel, angle value of the terminal relative to ground level can be obtained,
Corresponding saturation degree regulation is carried out according to the angle value, when terminal is more than vertical angle relative to ground level angle value, then with
The saturation degree of blue sky pixel is adjusted higher saturation degree.When terminal relative to ground level angle value less than vertical angle
When, blue sky pixel is adjusted with lower saturation degree.
Wherein, when terminal is more than vertical angle angle value relative to ground level angle value, illustrate terminal taking angle towards sky
Direction, it should strengthen the saturation degree of blue sky pixel to strengthen effect of optimization.Hung down when terminal is less than relative to ground level angle value

In one embodiment, this presets the ISO sensitivity values that photosensitive threshold value can be set for system, the ISO sensitivity
Value is larger, when detecting that current ISO sensitivity exceedes the default photosensitive threshold value, illustrates that current light intensity is too dark, user is very
In the space for being likely to be at night-time scene or closing.
In step S204, blue sky tone range is determined based on sensitivity.
In one embodiment, when the value for determining current ISO sensitivity, which is no more than, presets photosensitive threshold value, illustrate to work as
The image shot under preceding scene is likely to occur blue sky part, can draw blue sky tone range according to default formula.
Such as, blue sky tone range can be represented with H, blue sky tone range H ∈ [α1,α2]；
The α1=210-10 × [1- | ISO-100 | ÷ ISO]；
The α 2=210+10 × [1- | ISO-100 | ÷ ISO].
Wherein, this 210 be optimized parameter, can be adjusted according to actual conditions, the ISO be ISO sensitivity value.
It can be seen from formula when terminal is in interior, ISO sensitivity is about 100 or so, blue sky tone range H
Between 200 degree to 220 degree.When terminal is in outdoor, ISO sensitivity is about 500 or so, and blue sky tone range H is 208
Spend between 212 degree.When terminal is in outdoor, other similar blue sky tone chaff interferences are relatively few, blue sky tone range correspondence
Than larger, when terminal is in it is indoor when, other similar blue sky tone chaff interferences are relatively more, and blue sky tone range is correspondingly smaller,
To prevent from similar blue color being judged as blue sky tone.
Further, pixel of the angle of tone in the blue sky tone range is all blue sky pixel.
In step S205, the image collected under image acquisition modality is obtained, the pixel pair in image is determined
