Electronic iris function setting
Use a manual or fixed iris lens and set the lens aperture to the
shortest F stop. Set the EI/BLC switch to EI (electronic iris)-ON
position.
The dynamic range of the electronic iris will be as indicated in table
B.
CAUTION:
• The electronic iris is suitable for normal indoor use. When the
EI/BLC switch is set to the EI-ON position, do not use an auto-iris lens.
• If used under fluorescent light, the image may flicker. In such a case, change to
incandescent lighting or set the EI/BLC switch to the OFF position and use an auto-iris
lens.
• When shooting bright subjects, pay attention to the light angle in order to avoid or
minimize the smear phenomenon effect.
When using an auto-iris lens (for indoor/outdoor use)
Set the EI/BLC switch to the OFF position.
CAUTION:
If conditions are outside the electronic iris operation range or more than the maximum
illumination, it will cause saturation of the CCD. In that case, use a manual iris lens.
