Why do I get Error 0xBFF60493 when snapping a color Image from a AVT Stingray 145C connected to a Compact Vision System?

[GuenterMueller]

I have a AVT Stingray 145C connected to a NI-1455. I want to acquire images in Format 7 Mode 0 (1388 x 1038). The only Pixel Format that allows me to snap an image from the cameras is “Mono 8”. Any other Pixel Format results in error 0xBFF60493.  The attached PNG (MAX screenshot) shows a successful acquisition of a Mono8 image and the error message when trying to acquire a color image.
I have seen on ni.com/camera that the Compact Vision System is regrettably not mentioned in the list of compatible NI devices.
Is there a chance to support the acquisition of color images?

Hi Guenter,

I'm looking at replicating this error and determining the cause. The CVS should certainly support color cameras. Out of curiosity, if you put the Pixel Format to Mono8 (which you said did acquire correctly) but then go to the Bayer tab and force bayer decoding, does it show the same error?

Thanks,

Hi Eric.
When selecting "Mono 8", the Bayer Patterns "Use Hardware Value" and "None" result in a monochrome acquisition without errors.
Any other Bayer Pattern results in the error mentioned before.
Thanks for your help, Guenter

Bump.   No news on this channel ?

Hi Guenter,

I was able to replicate this here. What is happening is that when you click Snap/Grab in MAX we also display the acquired image on the VGA port on the CVS. For some reason the video driver on the CVS is reporting that the video mode we are trying to switch to is not valid. This seems to be a related to a combination of resolution and color format. To compound the problem, for some reason this is being reported as a fatal error.

For the time being, the easy workaround is to go to the remote image options configuration in MAX (Tools->NI Vision->Remote Image Options...) and turn off the option to "Display images on remote monitor." You'll still see images in MAX and you can still use the CVS's VGA port from within LabVIEW and Vision Builder AI (both have you select the video mode instead of trying to choose one automatically like MAX is doing).

Sorry you ran into this, but I've opened an issue for this item and hopefully it should be fixed in an upcoming release.

Great, Eric.  In fact, I did not try any of the options you have mentioned.
I will have a discussion with my colleagues and decide how to go further. We are preparing a quotation for a vision system that will check three products, each with one camera. The CVS is a perfect match for this application's demands.
We intend to connect 3 Stingray 145C to the CVS. Application development might be done in LabVIEW or VBAI - the decision is open. Color images are very welcome as we intend to identify parts by color.
Thanks for your support, Guenter
