It is not permitted to change the scanning range after having acquired
images. If you want to change the scanning range again, select
<Normal> from the list displayed below the [Surface XY-Norm] option
button in the [Mode] group box to set the scanning ragne to the
original setting, acquire an image in the XY observation mode, then
select <Clip> in the [Mode] group box and reselect the scanning range.
2-2-6 Image Acquisition by Magnifying the Rectangular Position (Zoom-In Scan)
The Zoom-In Scan mode limits the scanning area to the range to be observed and
acquires the image of that area by magnifying it.
For example, let us assume that an 800 x 600 pixel image is displayed in the [Live] panel
and the image acquisition area is limited to an area with 400 x 300 pixels (halved in both
X and Y directions).
When the image is acquired in this mode, the number of pixels in the X direction
becomes identical to the image size before start of this mode, and the magnification
applied is determined according to the size of the limited range. High-speed image
acquisition can be made possible by decreasing the number of pixels in the Y direction.
Please prepare hardware that is compatible with rotation scan (FV5-
IO3). If you use the FV5-IO2, the sizes of the acquirable images are
fixed as follows.
256x80, 320x81, 512x64, 640x58, 800x50, 1024x42, 2048x25
