(Note 10) 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
conditions) calculated by the following procedure.

PIXEL n PIXEL (n+ 1)
1) Two adjacent pixels (pixel n and n +1) in one reading are fixed as
measurement points.
2) Each of the output level at video output periods averaged over 200ns period to
get Vn and V(n +1).
3) V(n + 1) is subtracted from Vn to get AV.
AV=Vn-V(n+1)
4) The standard deviation of AV is calculated after procedure 2) and 3) are
repeated 30 times (30 readings).

6) 10 sigma values are averaged.

7) Evalue calculated using the above procedure is observed veitimes larger than
that measured relative to the ground level. So we specify random noise as
follows.

CAUTION
l. Window Glass
The dust and stain on the glass window of the package degrade optical performance of CCD
sensor.
Keep the glass window clean by saturating a cotton swab in alcohol and lightly wiping the surface,
and allow the glass to dry, by blowing with filtered dry N2.
Care should be taken to avoid mechanical or thermal shock because the glass window is easily to
damage.
2. Electrostatic Breakdown
Store in shorting clip or in conductive foam to avoid electrostatic breakdown.
3. Incident Light
CCD sensor is sensitive to infrared light.
Note that infrared light component degrades resolution and PRNU of CCD sensor.
4. Lead Frame Forming
Since this package is not strong against mechanical stress, you should not reform the lead frame.
We recommend to use a IC-inserter when you assemble to PCB.
