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
The dynamic range of the electronic iris will be as indicated in table
• 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
• 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.
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.
