Anti-blooming function
If the incident light intensity is higher than the saturation charge level, even partially, a signal charge in excess of the saturation
charge cannot accumulate in the photodiode. This excessive charge flows out into the video line degrading the signal purity. To
avoid this problem and maintain the signal purity, applying the same voltage as the Reset V voltage to the saturation control drain
and grounding the saturation control gate are effective. If the incident light intensity is extremely high, a positive bias should be
applied to the saturation control gate. The larger the voltage applied to the saturation control gate, the higher the function for
suppressing the excessive saturation charge will be. However, this voltage also lowers the amount of saturation charge, so an
optimum bias voltage should be selected.
I
Auxiliary functions
1) All reset
In normal operation, the accumulated charge in each photodiode is reset when the signal is read out. Besides this method that
uses the readout line, S3921/S3924 series can reset the photodiode charge by applying a pulse to the saturation control gate.
The amplitude of this pulse should be equal to the
φ

pulses and the pulse width should be longer than 5
μ
s.
When the saturation control gate is set at the
“
High
”
level, all photodiodes are reset to the saturation control drain potential.
Conversely, when the saturation control gate is set at the
“
Low
”
level (0 V), the signal charge accumulates in each photodiode
without being reset.
2) Dummy video
S3921/S3924 series have a dummy video line. Positive-polarity video signals with the DC offset remove can be obtained by
differential amplification of the active video line and dummy video line outputs. When not needed, leave this unconnected.
I
Precautions for using NMOS linear image sensors
1) Electrostatic countermeasures
NMOS linear image sensors are designed to resist static electrical charges. However, take sufficient cautions and countermea-
sures to prevent damage from static charges when handling the sensors.
2) Window
If dust or grime sticks to the surface of the light input window, it appears as a black blemish or smear on the image. Before using
the image sensor, the window surface should be cleaned. Wipe off the window surface with a soft cloth, cleaning paper or
cotton swab slightly moistened with organic solvent such as alcohol, and then lightly blow away with compressed air. Do not
rub the window with dry cloth or cotton swab as this may generate static electricity.
