ECLIPSER FUNCTION
When using a CCD camera with an auto-iris
lens, in a dark area with a light background not
enough contrast is obtained, since the back-
ground signal causes the auto-iris to close, re-
sulting in unclear images. However, when the
ECLIPSER function is operated together with
an auto-iris lens, the light background signal is
sliced and converted into a gray level video sig-
nal. With this signal, the auto-iris lens is oper-
ated, so that the iris is opened and sufficient
contrast can be obtained.
The ECLIPSER function switch can be turned
ON/OFF by moving #4 switch of Dip Switch
right and left.
(Factory setup is ECLIPSER OFF.)
CAUTION:
The ECLIPSER function must be used with an auto-
iris lens. When the auto-iris lens to be used is equipped
with a response selector (AVERAGE/PEAk), always set
it to AVERAGE.
