intensity

Did you check out my last screen shot posted? Put the histogram control inside the while loop so that you can see the change when you adjust the image setup.

Muks,

I looked at your block diagram and I am still trying to understand it.  It is still unclear to me how I get the imaq connected to my camera..  do I need to select a certain file path and how?  My camera is img0 but not sure how to hook that up to the imag create etc...

Thanks

muks,  I am able to get an image with a simple snap vi.  I am now trying to follow your example.. would you mind attaching it vi format so I can follow the wires better and use help to figure out the icons I dont understand.

Thanks,

C

I am still trying to figure out if there is a vi or a system of vi's I can use to get an intensity histogram of an image that I can manipulate.. I have attached a front panel example for further clarity.  unfortunately I dont have access to the block diagram..

Hi Calpe,

From looking up this error we typically see this when the data types are incompatible. For instance, a customer encountered this error when using a Grayscale (SGL) image where a Grayscale (U8) was necessary.

Some customers have also seen this error when the reference was null (no actual image).

This forum shows a customer who solved this error as well: http://forums.ni.com/ni/board/message?board.id=200&message.id=2008&requireLogin=False
