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.
