The block of pixels of high gray scale, if the block of pixels of the reflective high gray scale, in center, the block of pixels of surrounding is not anti-
The block of pixels of high gray scale can be grabbed image pattern, then the color of the RGB of same gray scale is filled out by the block of pixels of the low ash degree of light
It fills.
Further, if there are the block of pixels of high gray scale in the first imaging, second is imaged on same position, and there is no height
The block of pixels of gray scale then abandons the block of pixels of the high gray scale in the first imaging, will be present in the same position in the second imaging
Block of pixels is filled；
If first is imaged on the pixel that high gray scale is not present in same position there are the block of pixels of high gray scale in the second imaging
Block, then abandon the block of pixels of the high gray scale in the second imaging, and the block of pixels for the same position that will be present in the first imaging is subject to
Filling.
The reflective Grey imaging block of the first imaging of adjustment and the second imaging can also be but unlimited by way of editing, cutting
In this, how to adjust to set according to actual needs, herein with no restriction.
S5. the gray value of the block of pixels is not adjusted.
