Low rate and termination of frame grabbing using IMAQ image acquisition

[Mehdi_Es]

Hi, I have a fast camera which is connected to desktop computer through PCIe-1433 NI card. I have written a LabVIEW code to save all the frames of camera. Attached is the snapshot of the code. There are two wierd problems happening when I run the code. (1) The number of "read frames" and "acquired frames" are diffrent from each others. In other words, if camera take 100K images per second, I just can see and save 1K of these images. (2) The more strange problem is that after some point, for example 5 seconds, the rate of reading frames stops and doe snot change, as if the programs doe snot work. I really appreciate if anyone can help me figouring out the problem. Thanks

Thank you for not attaching a "snapshot" of the code.  I don't know what you intended to attach, but for a problem this complex, you must attach actual LabVIEW code (one or more complete VIs, with the file extension ".vi", and sufficient supporting VI's) so that we can make sense of your material.

You should also tell us the following particulars of your Image Acquisition:

• Describe the Image.  What is its dimension in Pixels?  Is it 8-bit Greyscale, RGB, or what?
• What is the Frame Rate?
• Describe the parameters of your Grab setup.  For example, how many Frame Buffers have you allocated?
• How is the Camera connected to the Computer?  What is the transmission speed of transmission?  TCP/IP, USB, something else?

We look forward to being able to examine your code.  Knowing what you want to do (partly answered by your response to the above Bullet Points) will help us to understand "what is possible".
