2-2-5 Image Acquisition of O nly the Rectangular Position (Clip Scan)
The Clip Scan mode limits the image acquisition range to the range to be observed and
acquires the image of only that range.
Applying this mode in an image acquisition mode involving large amount of data, such
as the XYZ, XYT and XYZT observation modes, makes it possible to acquire data of a
long period of time in a small file size.
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 size per pixel on the specimen is identical
to that before start of this mode.
1. Acquire an image in the XY observation mode. For the detailed operation method,
see section 2-2-1, “Image Acquisition in XY Observation Mode”.
2. Select the [Surface XY-Norm] option button in the [Mode] group box in the
[Acquire] panel, then select <Clip> from the list displayed below it.
A frame indicating the scanning range will be displayed in the [Live] panel.
In the initial setting, the image is displayed with both the X and Y sizes set to half
the original sizes.
3. Move the frame around the range to be observed. The frame can be moved by
placing the mouse pointer inside it and dragging.
