Note 9: Random noise is defined as the standard deviation (sigma) of the output level difference between two
adjacent effective pixels under no illumination (i.e. dark condition) calculated by the following procedure.
1) Two adjacent pixels (pixel n and n + 1) in one reading are fixed as measurement points.
2) Each of the output levels at video output periods averaged over 200 nanosecond period to get Vn and
3) Vn + 1 is subtracted from Vn to get ∆V.
4)
5) Procedure 2), 3) and 4) are repeated 10 times to get 10 sigma values.
6)
