≤i≤y）Row jth arranges（1≤j≤x）Data content be Q（I, j）W（I, j）；
For i-th（1≤i≤y）Capable data, then the 1st data of the row be recorded as original data content i.e. Q (i, 1), W (i,
1), the 2nd data are recorded as Q (i, 2)-Q (i, 1), W (i, 2)-W (i, 1), the 3rd data be recorded as Q (i, 3)-Q (i,
2), W (i, 3)-W (i, 2) ... ..., x-th data record are Q (i, x)-Q (i, x-1), W (i, x)-W (i, x-1), at this time
Enable A (i, 1)=Q (i, 1), S (i, 1)=W (i, 1)；A (i, 2)=Q (i, 2)-Q (i, 1), S (i, 2)=W (i, 2)-W (i,
1)；A (i, 3)=Q (i, 3)-Q (i, 2), S (i, 3)=W (i, 3)-W (i, 2)；……A(i,x)= Q(i,x)- Q(i,x-
1), S (i, x)=W (i, x)-W (i, x-1), then A（I, j）S（I, j）For the data after the area compresses that the i-th row jth arranges
Content, A（X, y）S（X, y）For the data content after the area compresses that y row xth arranges；
Without information loss when the photo of the compressed storage restores；
The decompression module specifically includes：
Image acquisition unit is compressed, when the decompression operation for receiving user when mobile terminal instructs, from memory module
Obtain the image for having been compressed resume module；
Second division unit, the x*y blocks region for the image for having been compressed resume module to be divided into y rows x row,
Middle x, y are positive integer；
Decompression unit, the original image data in the region for obtaining the i-th row first row in x*y blocks region, keeps it
Size is constant, and the image data in every piece of region after the i-th row first row is urined and is compressed to the compression of images number in the region
According to size plus it with the image compression data size in the region of all row before a line, i.e. Q（i,1）=A（i,1）, W（i,1）=S
（i,1）, Q (i, m)=A (i, m)+A (i, m-1)+...+A（i,1）, W (i, m)=S (i, m)+S (i, m-1)+...+S（i,1）；
Wherein Q (i, m), W (i, m) are the original image data size of the i-th row m column regions, and A (i, m), S (i, m) are the i-th row m row
Image data size after the compression of images in region, i are the natural number more than or equal to 1 and less than or equal to y, and m is more than 1 and to be less than
Natural number equal to x；
In the second division unit, dividing mode is consistent in the first division unit, and the dividing mode ensures that photo exists
Restore the initial data of photo during decompression with full symmetric inverse process；
In decompression unit, for i-th（1≤i≤y）Capable data, the 1st data content of this journey be A (i, 1), S (i, 1),
Then Q (i, 1)=A (i, 1), W (i, 1)=S (i, 1)；Second data content of this journey is Q (i, 2)=A (i, 1)+A (i, 2), W
(i,2)= S(i,1)+S(i,2)；..., x-th of data content of this journey be Q (i, x)=A (i, 1)+A (i, 2)+...+A (i,
X), W (i, x)=S (i, 1)+S (i, 2)+...+S (i, x).
