Overview
The dark-field correction and the bright-field correction are both part of the flat field correction that
corrects for DSNU and PRNU, which both require two different calibration processes.
The flat field correction is used to improve the quality of the image by removing the artifacts that are
caused by fixed pattern noise and variations in the pixel-to-pixel sensitivity of the detector. A flat
field correction corrects for dark signal non-uniformities (DSNU), photo response non-uniformities
(PRNU) and/or artifacts caused by the illumination and illumination optics. These application notes
describe how to calibrate the flat field functions and how to use them to improve the quality of the
image. These functions are available in all JetCam series cameras.
