PCI-1411 Even Start Field for Interlacing

[smwtcool]

I have a PCI-1411 and it is grabing the wrong two fields and interlacing them so the result is a grated and smeared image. In MAX I found where to select Frame or Field Mode and it tells me: "You can programmatically set the start field to odd or even and the interlacing will be handled automatically." But I cant find where to change which field is the start field.

Hi smwtcool,

You didn't mention what development environment you were using, but the method you want to use is pretty much the same. In LabVIEW, you'll want to use the property node to adjust the "Start Field" and "Acquire Field" properties. If you are using C/C++, use imgSetAttribute to adjust the IMG_ATTR_START_FIELD and IMG_ATTR_ACQUIRE_FIELD.

The acquire field is which of the two fields is acquired first. The start field is which field is displayed as the top line of the image. It sounds like for your application you'll want to set both of these to even.

Good luck,

Jeff

Jeff,

I'm using Labview, sry. But your directions were enough to get it resolved, thank you.
