In step s 11, default Gaussian Blur picture material is obtained.
Wherein, presetting Gaussian Blur picture material can be any picture with Gaussian Blur effect, certainly, for simplicity, can be selected for the most single picture with Gaussian Blur effect of color as default Gaussian Blur picture material.User can utilize existing Gaussian Blur fabrication techniques to go out to have the picture of Gaussian Blur effect, and as presetting Gaussian Blur picture material, existing a lot of graphics software all has Gaussian Blur function, utilizes this function, and user can produce default Gaussian Blur picture material easily.Or, user can also select oneself satisfied picture materials, and carry out RGB assignment with reference to having RGB (three primary colors) value of picture of the Gaussian Blur effect picture to selecting, so, picture after assignment just has Gaussian Blur effect, can be as default Gaussian Blur picture material.
In step s 12, original image is overlapped with default Gaussian Blur picture material, it is thus achieved that the image after superposition.
In step s 13, determine that the image after superposition is the target image with Gaussian Blur effect.
Use the technical scheme that disclosure embodiment provides, the target image of Gaussian Blur effect can be had by being overlapped original image and default Gaussian Blur picture material obtaining, for the existing Gaussian Blur method by image and Gauss distribution being made convolutional calculation, this technical scheme is while realizing Gaussian Blur effect, reduce computation complexity exponentially, thus reduce the power consumption of terminal, and there is real-time.
In one embodiment, as in figure 2 it is shown, step S12 can be embodied as following steps S21-S22.

Mode A3, determined the transparence value of default Gaussian Blur picture material by step S51-S53 as shown in Figure 5.
In step s 51, user's slide to the slide block on default transparency bar is received.
In step S52, determine, according to slide, the position that slide block is slid to.
In step S53, according to the corresponding relation between slide block position and transparence value on default transparency bar, determine the transparence value that position that slide block is slid to is corresponding, as the transparence value of default Gaussian Blur picture material.
During employing mode A3, presetting the most corresponding transparence value 0 in two ends and the transparency 100% of transparency bar, user can carry out slide to the slide block on default transparency bar, i.e. select between transparence value 0 and transparency 100%.
It can be seen that for compared to aforesaid way A2, which A3 makes user more fine to the selection of the transparence value of default Gaussian Blur picture material, selects more accurately so that user has in the degree that original image carries out Gaussian Blur.
Above-mentioned several ways make to preset the determination of the transparence value of Gaussian Blur picture material more accurately, fine, hommization, and the superposition weight presetting Gaussian Blur picture material can be enable to make dynamically adjustment according to the selection of user, so that the Gaussian Blur effect of target image more can meet the demand of user, improve the Experience Degree of user.
