This function processes images captured from the camera so that they can be easier-to-measure. Eight
filtering options are available so that you can set filtering different for each of position correction and actual
measurement.
When you move the cursor, a filtered image of the image at the cursor position is displayed on the right side of
the monitor. Set the filter while monitoring the image on screen.
