SETTINGS
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-ON
position.
Note:
Please refer to the specifications for dynamic
range of the electronic iris.
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.
