Referring to Fig. 1, Fig. 1 is the flow diagram 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, which is the sensitivity with digital representation to light
Degree.ISO sensitivity is higher, indicates stronger to the susceptibility of light.Therefore, high ISO sensitivity is suitble to shoot low illumination and movement
Object.
Further, it when terminal is in image acquisition modality, 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.For example, light intensity is stronger, and the value of ISO sensitivity is generally 100 or so when terminal is in outdoor.When terminal is in
When indoor, light intensity weakens, and the value of ISO sensitivity can become larger, and generally nearly 500.
In one embodiment, current environment light can be acquired by the cam device in terminal, by Image Acquisition
Sensor obtains current light intensity according to the current environment light, then determines the corresponding ISO sense of current light intensity
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, value range is 0 degree to 360 degree, by counterclockwise since red
Direction calculating, red are 0 degree, and green is 120 degree, and blue is 240 degree.Their complementary color is: yellow is 60 degree, cyan 180
Degree, magenta are 300 degree.Current blue sky optimization of region method only simply divides a region, if the pixel on image
Tone fall into the region, then be determined as blue sky pixel, and optimize, be such as determined as an area for 190 degree to 215 degree
Domain is then determined as blue sky pixel when the hue angle of the pixel on image falls into the region.
In one embodiment, when the value for determining current ISO sensitivity, which is no more than, presets photosensitive threshold value, explanation is worked as
The image shot under preceding scene is likely to occur blue sky part, can obtain blue sky tone range according to preset formula.
For example, blue sky tone range can be indicated 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 the actual situation, 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
It spends between 212 degree.When terminal is in outdoor, other similar blue sky tone chaff interferent is relatively smaller, and blue sky tone range is corresponding
It is bigger, when terminal is in it is indoor when, other similar blue sky tone chaff interferent is relatively more, blue sky tone range correspond to it is 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 s 103, the acquired image under image acquisition modality is obtained, determines the pixel pair in image
The tone answered.
Wherein, which is several lattices composition, and each lattice becomes a pixel, and terminal is by indicating this
The information such as position, color, the brightness of a little pixels, to represent entire image.
Further, the image that terminal currently acquires is obtained, determines the corresponding tone of each pixel in the image
Angle.
In step S104, according to blue sky tone range tone corresponding with the pixel in image, satisfy to pixel
It is 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 is confirmed as blue sky pixel.Then phase is carried out to the saturation degree of blue sky pixel
The adjusting answered, to achieve the purpose that blue sky optimizes.
In one embodiment, when determining blue sky pixel, angle value of the available terminal relative to ground level,
Carry out corresponding saturation degree adjusting according to the angle value, when terminal is greater than vertical angle relative to ground level angle value, then with
The saturation degree of blue sky pixel is adjusted in higher saturation degree.When terminal is less than vertical angle relative to ground level angle value
When, blue sky pixel is adjusted with lower saturation degree.
Wherein, when terminal is greater than vertical angle angle value relative to ground level angle value, illustrate terminal shooting angle towards sky
Direction, it should reinforce the saturation degree of blue sky pixel to reinforce effect of optimization.It hangs down when terminal is less than relative to ground level angle value
When right angle angle value, illustrate terminal shooting angle towards ground direction, it should with saturation degree appropriate to the saturation degree of blue sky pixel
It is adjusted, forms biggish contrast with real world images to avoid the image come is shot.

Further, when the light intensity is stronger, illustrate that current environment is brighter, image acquiring sensor can automatically turn down
ISO sensitivity illustrates that current environment is darker when the light intensity is weaker, image acquiring sensor can automatic adjustment height ISO it is photosensitive
Degree.Different light intensities is corresponding with corresponding ISO sensitivity, to guarantee the image quality of image.For example, when terminal is in room
When outer, light intensity is stronger, and the value of ISO sensitivity is generally 100 or so.When terminal is in interior, light intensity weakens,
The value of ISO sensitivity can become larger, and generally nearly 500.So image acquiring sensor can be determined according to current light intensity
Corresponding ISO sensitivity.
In step S203, whether detection sensitivity is more than to preset photosensitive threshold value.
It should be noted that when light intensity is weaker, the value of ISO sensitivity is bigger, when the value of ISO sensitivity is more than certain
When threshold value, illustrate that current light intensity is too dark, user is most likely in night-time scene or closed space.
Wherein, if it is detected that sensitivity is more than to preset photosensitive threshold value, S208 is thened follow the steps；If it is detected that sensitivity does not surpass
It crosses and presets photosensitive threshold value, then follow the steps S204.
In one embodiment, this, which presets photosensitive threshold value, to be the ISO sensitivity value of system setting, the ISO sensitivity
Be worth it is larger, when detect current ISO sensitivity be more than this preset photosensitive threshold value when, illustrate that current light intensity is too dark, user is very
It is likely to be in night-time scene or closed space.
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, explanation is worked as
The image shot under preceding scene is likely to occur blue sky part, can obtain blue sky tone range according to preset formula.
For example, blue sky tone range can be indicated 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 the actual situation, 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
It spends between 212 degree.When terminal is in outdoor, other similar blue sky tone chaff interferent is relatively smaller, and blue sky tone range is corresponding
It is bigger, when terminal is in it is indoor when, other similar blue sky tone chaff interferent is relatively more, blue sky tone range correspond to it is 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.
