Process a pending image in image as benchmark image, determine in the pending image of preset number in addition to benchmark image
Other pending image each, relative to the image shift amount of benchmark image；Wait to locate to each other according to image shift amount
Reason image carries out offset correction process.
In force, terminal, can be from above-mentioned multiple pending after being continuously shot the pending image of preset number
Arbitrarily choosing a pending image in image and be set to benchmark image, this sentences and takes image on the basis of first pending image
As a example by, it is briefly described.Afterwards, during terminal may determine that preset number pending image in addition to benchmark image each its
Its image, relative to the image shift amount of benchmark image.Determine the image shift relative to benchmark image of other pending image
The process of amount is varied, is referred to the processing mode in the middle of prior art, such as existing patent CN104809716A, the most not
Repeat again.After determining image shift amount, other pending image each can be offset by terminal according to image shift amount
Correcting process, concrete, if certain other pending image B relative to benchmark image A general image to left avertence 2 pixels
The position downward bias position of 1 pixel of point, then the image shift amount of other pending image B is (-2 ,-1), the most permissible
Each pixel in other pending image B, to the position of two pixels of right translation, is translated up the position of 1 pixel
Put, and then the process of the offset correction to other pending image B can be completed.It is noted that after offset correction, other
The pixel value of border area pixels point newly-increased in pending image can directly continue to use correspondence position pixel in benchmark image
Pixel value, such as, based on the example above, after other pending image B is carried out offset correction process, other pending image
In B, the rightmost side 2 example pixel and top side 1 row pixel are newly-increased border area pixels point, then can be by benchmark image
The rightmost side 2 example pixel and the pixel value of top side 1 row pixel, be defined as the newly-increased border area pixels point of correspondence position

After selected reference image, can click on and arrange button certain pending image is set to benchmark image, at this moment, terminal can connect
The the first pending image receiving user's input selects instruction, such that it is able to the first pending image is set to benchmark image.
So, user manually select, can be prevented effectively from owing in benchmark image, noise too much causes the letter of last enlarged drawing picture
Make an uproar than relatively low problem.
Step 102, based on the pixel value of the pixel of correspondence position in different pending images, carries out pixel value equalization
Process, obtain average image.
In force, terminal, after being continuously shot multiple pending image, can obtain pixel in multiple pending image
The pixel value of point.Obtain it is understood that the most quickly shoot due to the plurality of pending image, permissible
Think that the pixel value of the pixel of the plurality of pending image correspondence position is the same outside the impact getting rid of noise.So,
In the case of considering noise, the pixel value of the pixel of correspondence position in different pending images can be carried out pixel value and put down
Homogenizing processes, and then obtains average image, and so, in average image, the noise in each pending image is to average image
Impact will greatly reduce.
Based on the above-mentioned process being provided with dynamic pixel point, accordingly, the process of step 102 can be such that by each its
In its pending image, the pixel value of the pixel of dynamic area replaces with the pixel value of correspondence position pixel in benchmark image；
Calculating in the pending image of preset number, the meansigma methods of the pixel value of correspondence position pixel, as corresponding in average image
