- To specify an area, the screen must be in the freeze image mode.
- The binary image display after changing the screen from "freeze" to "through," and finally back
to "freeze," will be a binary image of the object that was captured the first time the IV-S30 was in
the "freeze" mode.
The binary image that is captured in the "freeze" mode the third time can be displayed when you
specify items 2 to 0 in the settings.
