Aquiring wrong data from camera

Configuration: Win7-64x, matlab r2013b, camera JAI-5000M-cxp6x2, grabber activesilicon Firebird

I am able to capture the video with other programs shipped with the camera and the grabber, so it seems that drivers are fine, devices are set up as they should.

imaqtool starts with errors, but still starts. I am able to start preview and able to 'log' data to memory and to export it to matlab workspace. But streaming and captured data is unrecognizable, as if sensor is read out partly, the image is some noise.

Any ideas?

Did you specify the colorspace to return? http://www.mathworks.com/help/imaq/returnedcolorspace.html

[Greg]

Hi, Walter, thanks for reply. ColorSpace property was set by default as 'grayscale'. Now I've tried 2014 ver of Matlab just now, hoping some new features were added, since gentl is rather modern transport layer. In 2014 matlab preview starts (aquistion does not) but the screen is absolutely black. And it seems data logging doesnt occur and no export to workspace is available...
