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

5) Procedure 2), 3) and 4) are repeated 10 times to get sigma value.
6) 10 sigma values are averaged.

7) Fualue calculated using the above procedure is observed V2 times larger

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.
This device has some weakly terminals for static electricity. Therefor, please pay attention to treat
this device.
CCD Image Sensor is protected against static electricity, but inferior puncture mode device due to
static electricity is sometimes detected. In handing the device, it is necessary to execute the
following static electricity preventive measures, in order to prevent the trouble rate increase of the
manufacturing system due to static electricity.
a. Prevent the generation of static electricity due to friction by making the work with bare hands
or by putting on cotton gloves and non-charging working clothes.
b. Discharge the static electricity by providing earth plate or earth wire on the floor, door or stand
of the work room.
c. Ground the tools such as soldering iron, radio cutting pliers of or pincer.
It is not necessarily required to execute all precaution items for static electricity.
It is all right to mitigate the precautions by confirming that the trouble rate within the
prescribed range.
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.
