Example, shall fall within the protection scope of the present invention.
A kind of image processing method provided by the invention and shifting is discussed in detail below by several specific embodiments are enumerated
Dynamic terminal.
Referring to Fig.1, a kind of step flow chart of image processing method of the embodiment of the present invention one is shown, specifically can wrap
Include following steps:
Step 101, the overexposure region in image to be processed is determined.
Wherein, image to be processed can be the image of various formats, can be the photo shot by current mobile terminal,
Or pass through network or the image of application downloading.
Overexposure region includes several overexposure pixels, overexposure refer to that aperture is excessive or shutter it is excessively slow caused by pixel
Brightness value is excessively high, photo whiting.
Specifically, pixel of the brightness value higher than certain threshold value, these pixel groups in image to be processed can be identified
At region be overexposure region.
Step 102, to there are the images to be processed of overexposure region to carry out color range correction.
In embodiments of the present invention, when, there are when overexposure region, needing to handle overexposure region in image to be processed,
Color range correction is carried out first before treatment, so that more uniform light and shade tone is presented in image to be processed；When in image to be processed
There is no overexposure regions, or when causing to determine overexposure region failure due to other reasons, do not carry out overexposure to the image to be processed
Processing and color range correction.
Specifically, the step of color range corrects specifically includes that the pixel too small firstly, for brightness value, and brightness value is mentioned
It is high；Then, the pixel excessive for brightness value suitably reduces brightness value.As Fig. 2 (A) show the color range of an image
The brightness value of schematic diagram, left end is too small, and the brightness value of right end is excessive, has had already appeared spillover；As shown in Fig. 2 (B)
Brightness value for color range schematic diagram of the image after color range correction, left end increases by appropriate, the brightness of right end
Value reduces by appropriate, so that the whole color range of image is in a suitable range.
Step 103, according to the brightness of the overexposure region and non-overexposure region, coloration and saturation degree, respectively to described
Brightness, coloration and the saturation degree of overexposure region are adjusted, and the non-overexposure region is mistake described in the image to be processed
Expose the region except region.
Wherein, brightness is the light levels of pixel, and value is 0 to 255.
Coloration is the expression of color intensity, and value is 0 to 255.
Saturation degree is degree of the color deviation with brightness grey, and value is 0 to 255.

It is appreciated that first function relationship is used to embody the letter between the brightness of overexposure region and the brightness of non-overexposure region
Number relationship；Second function relationship is used to embody the functional relation between the coloration of overexposure region and the coloration of non-overexposure region, the
Three functional relations are used to embody the functional relation between the saturation degree of overexposure region and the saturation degree of non-overexposure region.
Specifically, when establishing functional relation, suitable function model, preferably linear model can be chosen, for example, y=
Ax+b, wherein coefficient a can determine according to the brightness ratio of overexposure region and non-overexposure region, b can according to the value of a and
Practical application scene setting, x are the input value of functional relation, are in embodiments of the present invention respectively former brightness, coloration, saturation
Degree, y are the output valve of functional relation, brightness, coloration, saturation degree after respectively adjusting in embodiments of the present invention.
Sub-step 1032, according to the first function relationship, second function relationship and third functional relation, respectively to institute
Brightness, coloration and the saturation degree for stating overexposure region are adjusted.
Specifically, for each pixel in overexposure region, its original brightness value is input in first function relationship, is obtained
The output arrived is brightness value adjusted, and replaces former brightness value；Its primary chromaticity values is input in second function relationship, is obtained
Output be chromatic value adjusted, and replace primary chromaticity values；Its original intensity value is input in third functional relation, is obtained
Intensity value adjusted, and replace former intensity value.
