Step S110：Obtain the monochrome information of display viewing area image.
First, general display is the display device of an i rows j row, then the display can regard i*j pixel groups as
Into dot matrix, it is assumed that each pixel includes three sub-pixels：Red pixel R, green pixel G and blue pixel B, the then display
I*j*3 sub- pixel-matrixs can be regarded as, for example, for the display of 5 rows 5 row, the display can be regarded as simultaneously
It is 5*15 sub-pixel dot matrix, is to be directed to display when the image to display viewing area carries out luminance compensation
Each sub-pixel is that unit carries out luminance compensation.
Wherein, the monochrome information of display viewing area image is obtained, that is, obtains each of display viewing area image
The brightness value of pixel, obtaining the brightness value of each pixel can be obtained by imaging sensor.
Step S120：Mura offset tables are obtained according to the monochrome information.
Mura offset tables are the brightness value and object brightness in viewing area image according to each pixel of above-mentioned acquisition
What value was determined, the brightness value of viewing area image is obtained by above-mentioned imaging sensor, and target brightness value can be advance
The average value that setting or viewing area image according to acquisition brightness value is obtained, so by each pixel
Target brightness value subtracts each pixel can obtain the offset table of each pixel in the brightness value of viewing area image, then
The mura offset tables of viewing area image can further be obtained.
