Through software, you can select one of the following types of frame
acquisitions:
• Interlaced frames, starting with the next even field (the default),
• Interlaced frames, starting with the next odd field;,
• Interlaced frames, starting with the next field (odd or even), or
• Noninterlaced frames.
Scaling Frames
For area-scan operations only, you can scale a frame by discarding
pixels, lines, or both through software. This is useful if you want to
reduce the size of an image.
You provide a scale factor for both the horizontal direction (range
between pixels) and the vertical direction (range between lines).
The minimum scale factor is 1 (the default); the maximum scale factor
is 16. For example, to scale an image so that every 16th pixel is
displayed, set the horizontal scale factor to 16. To scale the image so
that every other line is displayed, set the vertical scale factor to 2. For
a one-to-one representation, set the scale factor to 1.
Frame Storage Mode
On the DT3152-LS, frame data is stored in monochrome format, or
8-bits per pixel.
