pixel decimation with PXI-1408

[zomer]

I'd like to reduce the number of pixel during the acquisition of a CCD (CCIR type) image using my PXI-1408 board. Although this is mentioned in the catalogue ('pixel decimation') i cannot find the wright vi to do it. Could you explain me how to do it ?
It is also mention that i can programme the gain of teh input video signal but i cannot see how ?

If you want to change the configuration settings programatically, you can use a property node from the Image Acquisition Palette. Input the session id from you IMAQ Session, select what you want to change in the property node, and set the values. The same can be done for the gain settings. I hope this helps!

Thanks, do you have an example (it's still hard to find what format to use with the Property-Node )?

I have attached a quick grab example with a property node...you can try using the different available properties to get what you want!
Good Luck

Zomer,

First figure out how to do what you want using MAX. For the two items you mentioned, I believe you want to change the scale (for pixel decimation) and Reference Levels (for gain). They are both on the Basic page of the properties for your camera.

Once you know which properties you want to change, you can change them in your program using a property node.
