Referring to Fig. 1, Fig. 1 is that the embodiment of the present invention provides a kind of schematic flow diagram of image processing method, is propped up as shown in the figure
The method of paying may include following steps：
S101, terminal judge whether the brightness value of current image to be captured is less than predetermined luminance threshold value.
Wherein, terminal refers to the terminals such as mobile phone, tablet personal computer, wearable device, in embodiments of the present invention, terminal tool
There is front camera, so that user can be autodyned using terminal.
Alternatively, in one embodiment of the invention, the terminal has screen backlight and proactive light emitting diode
(Light Emitting Diode, LED) light compensating lamp so that when user is autodyned using the terminal, if shoot light compared with
It is weak, then light filling can be carried out to ambient light using proactive LED light supplement lamp or screen backlight, improve and shoot light.
Wherein, current image to be captured refers to the image that terminal needs are shot, in embodiments of the present invention, when terminal is utilized
When front camera is autodyned, the current image to be captured can refer to this human head picture of user.
Wherein, the brightness value (Brightness Value, BV) of current image to be captured is typically determined by the light of environment
Fixed, when in the environment that current object to be shot is in dark, the brightness value of current image to be captured will be relatively low, conversely,
When in the environment that current object to be shot is in bright light, the brightness value of current image to be captured will be brighter.
Wherein, predetermined luminance threshold value refers to for determining whether one in low light environment assesses current image to be captured
Threshold value, so that when the brightness value of current image to be captured is less than predetermined luminance threshold value, it is determined that current image to be captured is in weak
Luminous environment, and when the brightness value of current image to be captured is higher than predetermined luminance threshold value, it is determined that current image to be captured is in by force
Luminous environment.
Alternatively, in one embodiment of the invention, the predetermined luminance threshold value is 30.
Specifically, in one embodiment of the invention, in terminal camera image-signal processor (image
Signal processor, ISP) calculate current image frame brightness value after, then terminal judges whether the brightness value is less than again
Predetermined luminance threshold value.
If S102, the brightness value of the current image to be captured are less than predetermined luminance threshold value, working as the terminal is judged
Whether preceding sensitivity value is more than or equal to default sensitivity threshold value.
In embodiments of the present invention, when the brightness value of current image to be captured is less than predetermined luminance threshold value, illustrate now
Current image to be captured is under low light environment, so now terminal needs use to be shot compared with ISO ISO.
Alternatively, in one embodiment of the invention, if the brightness value of current image to be captured is greater than or equal to default
During luminance threshold, terminal current image to be captured by normal photographing.
It is appreciated that the brightness value by detecting image to be captured, thus under different brightness values terminal will perform difference
Operation, can further trigger different screening-modes.
Wherein, the default sensitivity threshold value refers to an assessment threshold whether excessive for the current sensitivity that determines terminal
Value, so as to when the current sensitivity value for detecting terminal is more than default sensitivity threshold value, determine the current sensitivity value of terminal
It is too high, namely now because the brightness of image to be captured is too low and uses higher sensitivity, so as to now shoot obtained figure
As noise will be than larger；And when the current sensitivity value of terminal is less than or equal to default sensitivity threshold value, determine terminal
Current sensitivity value will not be too high, namely the now brightness of image to be captured is enough, so video camera is when shooting and does not need
Using higher sensitivity, so that it is few to shoot the image noise come.
Alternatively, in one embodiment of the invention, the default sensitivity threshold value could be arranged to 1000.
Specifically, in one embodiment of the invention, when camera control module receives photographing instruction in terminal,
Detect whether current ISO values exceed default sensitivity threshold value.
If the current sensitivity value of S103, the terminal is more than or equal to default sensitivity threshold value, shoot described current
Image to be captured obtains shooting image.
S104, to the shooting image carry out potting gum processing obtain the first view data.
Wherein, the first view data refer to it is corresponding with current taken image, to shooting image carry out potting gum processing
The view data obtained afterwards.
Specifically, in one embodiment of the invention, the size of the shooting image is M*M pixels, described to described
Shooting image carries out potting gum processing and obtains the first view data, including：
Piecemeal processing is carried out to the shooting image and obtains the image subblock that (M/N) * (M/N) individual size is N*N pixels, institute
M, N are stated for positive integer；
The pixel value phase adduction of N*N pixel in described image sub-block is averaged as described image sub-block
Merge pixel value；
It is the data being made up of the merging pixel value of described image sub-block, first figure to determine described first image data
As size of data is (M/N) * (M/N) pixel.
For example, in the example of the present invention,, should if N is 4 if shooting image is the image of M*M pixels
Shooting image is divided into the image subblock of the individual 4*4 pixels of (M/4) * (M/4), then pixel again to the pixel in each image subblock
Value is added the new pixel value averaged as the image subblock, will finally obtain the new image of (M/4) * (M/4) size
Data, namely the first view data, it will be understood that the new view data by for the 1/N of the resolution ratio of original shooting image,
It is 1/4 herein.
Alternatively, in one embodiment of the invention, the mode of this pair of shooting image progress potting gum processing is
Binning patterns.
It is appreciated that when carrying out image output using aforesaid way, because the pixel value of each pixel of output is adjacent
The average value of pixel, it is possible to smooth noise, improves signal noise ratio (snr) of image, sensitivity and output speed, reduces the noise of image
And resolution ratio, the overall quality for improving image.But during using binning pattern output images, the resolution ratio of image will be only complete
The 1/4 of size.
In embodiments of the present invention, when the current sensitivity of terminal is excessive, the noise for shooting obtained shooting image will
Than larger, and after being handled due to binning patterns image, the resolution ratio of image can be reduced, so can now select
Select in binning pattern output images.
Alternatively, in one embodiment of the invention, if the current sensitivity value of the terminal is less than default sensitivity
Threshold value, now terminal by normal photographing the image to be captured.
For example, in the example of the present invention, when being autodyned in the environment of user is in dark, being
Guarantee shooting effect, terminal detects that the brightness value of active user auto heterodyne head portrait (namely may be considered current to be captured first
The brightness value of image) whether it is less than 30, when detecting the brightness value less than 30, now illustrate the brightness of current image to be captured
Value is too small, and the environment residing for user is too dark, and now in order that shooting obtained image is unlikely to too dark, terminal needs to improve shooting
The sensitivity of head, but due to sensitivity it is too high when, it is big by noise to shoot obtained image, so when detecting the photosensitive of camera
Degree than it is larger when, binning pattern output images will be now used, to reduce the noise of image.
Alternatively, in one embodiment of the invention, it is described shoot the current image to be captured before or described clap
When taking the photograph the current image to be captured, methods described also includes：
Light filling is carried out to the current image to be captured, to improve the brightness value of the current image to be captured.
It is appreciated that in an embodiment of the present invention, when the dark of current image to be captured, now in order to ensure
Shooting effect, shooting image can be treated before shooting and carries out light filling, bright and clear after light filling, terminal judges figure to be captured
The brightness of picture is low to be higher than predetermined luminance threshold value, and it is good to shoot now namely directly obtained shooting image quality, subsequently can be direct
Shooting image is exported using normal mode, and light is still not sufficient enough after light filling, but can also carry to a certain extent
High image quality, so, shooting can be greatly enhanced by carrying out light filling to current image to be captured before shooting or when shooting
The picture quality of image.
Specifically, in one embodiment of the invention, it is described that light filling is carried out to the current image to be captured, including：
Light filling is carried out to the current image to be captured using proactive light emitting diode light compensating lamp or screen backlight.
Alternatively, in one embodiment of the invention, when terminal has proactive light emitting diode light compensating lamp, preferably select
Select proactive light emitting diode light compensating lamp and light filling is carried out to current image to be captured, when proactive light emitting diode light filling is not present in terminal
During lamp, screen backlight can be used to carry out light filling to current image to be captured.
Specifically, in one embodiment of the invention, proactive light emitting diode can be controlled by camera control module
Light compensating lamp or screen backlight carry out light filling to current image to be captured.
Specifically, when carrying out light filling using screen backlight, screen background color settings can be particular color by terminal, and
Screen backlight is set as system maximum brightness, the face of user is projected using the backlight of screen, the face for improving user is whole
Body brightness.
For example, in the example of the present invention, when being autodyned in the environment of user is in dark, being
Guarantee shooting effect, terminal detects that the brightness value of active user auto heterodyne head portrait (namely may be considered current to be captured first
The brightness value of image) whether it is less than 30, when detecting the brightness value less than 30, now illustrate the brightness of current image to be captured
Value is too small, and the environment residing for user is too dark, so light filling now can be carried out using proactive light emitting diode first, improves and waits to clap
Take the photograph the brightness value of image.But due to still will not be very good by the effect after terminal light filling, now in order that shooting obtained image
Be unlikely to too dark, now terminal needs to improve the sensitivity of camera, but due to sensitivity it is too high when, shooting obtained image will
Noise is big, thus when detect the sensitivity of camera than it is larger when, binning pattern output images will be now used, to drop
The noise of low image.
Alternatively, in another embodiment of the present invention, after light filling, due to improving the brightness of image to be captured
Value, so now the sensitivity value of the camera of terminal and need not set too high, will not so as to shoot obtained image noise
Can be too big, so do not need to use now binning patterns output image to reduce the noise of image, will be with normal pattern
Output image.
Alternatively, in one embodiment of the invention, can also simultaneously using proactive light emitting diode light compensating lamp and
Screen backlight carries out light filling to current image to be captured.
Further, in one embodiment of the invention, when the ISO for detecting terminal is too high, if being now used only
Proactive light emitting diode light compensating lamp carries out light filling, can further open screen backlight and carry out light filling；When only used screen back
Light carries out light filling, can further open proactive light emitting diode light compensating lamp and carry out light filling.
It is appreciated that because when user autodynes in night scene, the light lighted using preceding shooting light compensating lamp can be direct
It is irradiated on face, so light filling very effectively can be carried out to current image to be captured using proactive light compensating lamp, and if i.e.
Make proactive light compensating lamp is not present, can also improve the brightness of current image to be captured, Jin Erti to a certain extent using screen backlight
The picture quality that high night scene is autodyned.
Alternatively, in one embodiment of the invention, it is described that shooting image progress potting gum processing is obtained
After first view data, methods described also includes：
Described first image data are entered with row interpolation adjustment using pre-set image interpolation algorithm, the of default resolution ratio is obtained
Two view data.
Wherein, image interpolation algorithm refers to that the image relatively low to resolution ratio is carried out after pixel point interpolation, to obtain compared with high score
The method of the image of resolution.
Specifically, in one embodiment of the invention, the image interpolation algorithm can be in following image interpolation algorithm
It is any：Nearest picture element interpolation algorithm, bilinear interpolation algorithm and bicubic interpolation algorithm.
Wherein, nearest picture element interpolation algorithm is a kind of simplest interpolation algorithm, when picture amplifies, and the pixel lacked is led to
Cross and directly generated using the color of immediate original pixel therewith；Each pixel of the image of bilinear interpolation algorithm output
It is the result for having four pixel (2*2) computings in figure；Each pixel of bicubic interpolation algorithm output image is artwork 16
The result of pixel (4*4) computing.
It is appreciated that because the resolution ratio of the first view data exported by binning patterns is relatively low, so in order to carry
The resolution ratio of hi-vision, can cause image interpolation algorithm to enter row interpolation to the first view data and obtain the second view data, with
Improve the resolution ratio for shooting obtained image.
Alternatively, in one embodiment of the invention, the utilization pre-set image interpolation algorithm is to described first image
Data enter row interpolation adjustment, and after the second view data for obtaining default resolution ratio, methods described also includes：
Second view data is encoded using pre-set image encryption algorithm, to obtain coded image.
Wherein, pre-set image encryption algorithm refers to for being encoded to the view data that camera is got, and is meeting
Under the requirement of certain fidelity, line translation, coding and compression are entered to view data, redundant data reduction is removed and represents digitized map
The data volume needed during picture, in order to the storage and transmission of image.Damaged with less data amount or nondestructively represent original
Picture element matrix technology.
Image compression encoding can be divided into two classes：One class is reversible, i.e., can recover original completely from the data after compression
Image, information do not lose, referred to as lossless compression-encoding, such as portable network image (Portable Networf
Graphics, PNG) it is conventional Lossless Image Compression Algorithm coding method；It is another kind of be it is irreversible, i.e., from the data after compression without
Method recovers original image completely, and information has certain loss, and referred to as lossy compression method is encoded, for example, JPEG
(Joint Photographic Experts Group, JPEG) is conventional image lossy compression method coding method.
In embodiments of the present invention, different Image Coding Algorithms can be used to encode the second view data
The image of different-format.For example, the coded image for obtaining jpeg format using JPEG modes is checked for user.
It is appreciated that coding is compressed to the second view data by using appropriate Image Compression Coding Algorithm, with
Relatively user is shown with transmitting shooting image in terminal.

And processing obtains the first view data.Terminal is less than predetermined luminance threshold by the brightness value of the current image to be captured in terminal
Value, and the current sensitivity value of terminal camera are carried out at potting gum higher than when presetting sensitivity threshold value to shooting image
Reason, so as to improve signal noise ratio (snr) of image, sensitivity and output speed, reduces the noise and resolution ratio of image, lifts overall diagram
