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 video bias 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.  
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, S3901/S3904 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 φ1, φ2 and φst pulses and the pulse width should be longer than 5 µs.  
When the saturation control gate is set at the Highlevel, all photodiodes are reset to the saturation control drain potential  
(equal to video bias). Conversely, when the saturation control gate is set at the Lowlevel (0 V), the signal charge accumulates  
in each photodiode without being reset.  
2) Dummy video  
S3901/S3904 series have a dummy video line to eliminate spike noise contained in the video output waveform. Video signal  
with lower spike noise can be obtained by differential amplification applied between the active video line and dummy video  
line outputs. When not needed, leave this unconnected.  
Handling precautions  
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.
