σCDS

Random noise (CDS)

σCDS is defined as the standard deviation of a valid pixel output signal with 100 times (=

100 lines) data sampling at dark (light shielding). This is measured by the following procedure.

1. One valid photocell in one reading is fixed as measurement point.

5. Repeat the above procedure (1 to 4) for 100 times (= 100 lines).

6. Calculate the standard deviation

σCDS using the following formula.
