Example, shall fall within the protection scope of the present invention.
Referring to Fig.1, the step flow chart for showing a kind of method of image procossing of one embodiment of the invention, specifically may be used
To include the following steps：
Step 101, the first image of camera acquisition is obtained；
It should be noted that this method can be applied in mobile terminal.For example, mobile phone, tablet computer or other tools
There is the electronic equipment of camera function.The present embodiment is not construed as limiting the concrete type of mobile terminal.
In embodiments of the present invention, the first image can be the image acquired by the camera of mobile terminal, which can
With with higher pixel value.In general, there is higher picture quality using the image that the shooting of higher pixel value obtains.
It should be noted that the pixel value of the first image can shoot the picture obtained with the camera of mobile terminal
What plain value matched.If for example, the camera of mobile terminal can shoot obtain 2000W pixels image, the first image
Pixel value highest can be 2000W pixels.
Alternatively, the pixel value of the first image can be the pixel value being voluntarily arranged by user.In general, what user was voluntarily arranged
The camera that pixel value should be less than mobile terminal can shoot the max pixel value obtained.If for example, the camera shooting of mobile terminal
Head can shoot the image for obtaining 2000W pixels, then user can voluntarily be arranged and not surpassed when shooting according to actual needs
First image of the 2000W pixels crossed.
Step 102, down-sampling processing is carried out to described first image, generates the second image；
Down-sampling (Subsampled) is a kind of processing operation of image, and principle is：For the figure that a width size is M*N
Picture carries out it s times of down-sampling to get to the image in different resolution of (M/s) * (N/s) size.
In embodiments of the present invention, down-sampling processing is carried out to the first image, the second figure compared with low-pixel value can be obtained
Picture.
For example, if the pixel value of the first image is 2000W, handled by down-sampling, it is 500W's that can obtain pixel value
Second image.Certainly, the pixel value size for the second image that down-sampling processing obtains being carried out to the first image can be according to reality
Sample rate determine that the sample rate can according to actual needs determine by those skilled in the art or user when actually taking pictures,
The present embodiment is not construed as limiting this.
Step 103, default processing is carried out to second image, generates third image, the default processing includes U.S. face
Processing and/or virtualization processing；
In embodiments of the present invention, there is lower pixel value compared to the first image due to the second image, right
The power consumption that second image carries out spent by the subsequent processing, is less, and the time is shorter.
For example, face can be helped to handle the second image, alternatively, making virtualization processing to the second image, compared to directly right
It is shorter that first image of higher pixel value makees processing or virtualization processing, the time it takes per sample.It is of course also possible to according to reality
It needs, while helping face and virtualization to handle the second image, the present embodiment is not construed as limiting this.
It should be noted that U.S. face and/or virtualization processing influence less the pixel value of image.That is, to
The third image that two images obtain after helping face and/or virtualization to handle, pixel value variation are little.
For example, the second image is the image of 500W pixels, then the pixel value of U.S. face and/or virtualization treated third image
It also should be in 500W or so.
Step 104, interpolation processing is carried out to the third image, generates target image, the pixel value of the target image
Difference between the pixel value of described first image is less than predetermined threshold value.
In embodiments of the present invention, due to before carrying out U.S. face and/or virtualization processing to image, being adopted under having been carried out to image
Sample processing, reduces the pixel value of image, therefore, after completing U.S. face and/or virtualization processing, can continue to make third image
Interpolation processing obtains target image.
Interpolation (Interpolating) also referred to as up-samples (Upsampling), exactly utilizes known vicinity points
Gray value (or three color values in RGB image) generates the gray value of unknown pixel point, has to be regenerated by original image
The image of higher resolution.
In embodiments of the present invention, between the pixel value of the target image after interpolation processing and the pixel value of the first image
Difference can be less than predetermined threshold value.Those skilled in the art can determine the specific size of predetermined threshold value according to actual needs, this
Embodiment is not construed as limiting this.
In the concrete realization, in order to obtain the target image almost the same with the pixel value of the first image, then can use up can
Smaller predetermined threshold value can be set.
For example, if the first image is 2000W, if wishing the picture of the target image obtained after U.S. face and/or virtualization processing
A smaller predetermined threshold value can be then arranged close to 2000W in element value, to the third image progress compared with low-pixel value
After interpolation processing, the target image of a higher pixel value can be obtained.
In embodiments of the present invention, after the first image for obtaining camera acquisition, directly the first image is not helped
The processing such as face, virtualization, but be the second image compared with low-pixel value by the first image procossing by down-sampling, then to the second figure
As helping the processing such as face, virtualization, and then the target image that third image restoring is original pixel value is carried by interpolation processing again
