The flat fied correction can be used to remove artifacts from the images that are caused by variations in the pixel-to-pixel sensitivity of the detector and/or by the distortions in the optical path. Here the correction consists in providing a reference image taken using a uniform photon exposure. Then each raw image will be corrected by dividing the pixel values by their corresponding reference values (flatfield image pixels).
To set the correction you must provide to the device a flatfield image file (setFlatFieldImage command) and then start the correction (start command).
