Flat Field Correction Control

FFC (Filed Flat Correction) is used for correcting non-uniformity of image brightness resulting from lens or
image sensor. When using this camera, FFC should be used because image sensor has fixed pattern noise.
Each pixel of image can be correcting with FFC function.
The correcting value of FFC function is calculating with information of acquired multiple image
