3.7.7 Returning Pixel Coefficient Information
Returning FPN and PRNU Coefficients
Pu rp ose:
Retu rns all the cu rrent p ixel coefficients in the ord er FPN , PRN U,
FPN, PRNU… for the range specified by the
x
and
y
coord inates.
The cam era also retu rns the p ixel nu m ber w ith every fifth coefficient.
WARN IN G: Do not d isp lay all p ixel coefficients at one tim e. Keep
the nu m ber of p ixels sm all (a sam p le size of 10 x 10 p ixel is
recom m end ed ) to avoid w aiting too long for the cam era to retu rn
inform ation. Coefficient ou tp u t can be halted by send ing any
character (hitting any key on the keyboard ).
