7.1.4 Fixed Pattern Noise Correction (FPNC)
CMOS sensors exhibit nonuniformities that are called Fixed Pattern Noise (FPN). How-
ever it is no noise but a xed variation from pixel to pixel that can be corrected. The advan-
tage of using this correction is a more homogeneous picture which may simplify the image
analysis. Variations from pixel to pixel of the dark signal are called dark signal nonunifor-
mity (DSNU) whereas photo response nonuniformity (PRNU) describes variations of the
sensitivity. DNSU is corrected via an offset while PRNU is corrected by a factor.
