Acquire sequences of image

[Raffaele96]

Hello,

I am trying to capture a series of images at a set frame rate and for a preset duration. I attach the script that I'm using. The problem is that if I set a number of images greater than 300 I get this error: "Error -1074396159 Not enough memory for requested operation". My computer is not full and the memory is not a problem. 

I'm using the 2020 version of labview with an USB camera.

Thanks everyone for the help.

Nothing is attached.  Make sure it is an actual VI.  You mentioned "script" but LabVIEW doesn't have scripts.

Sorry I don't know why it isn't attached to the previous message.

How much memory does each image take?  300 is a lot of images.  What exactly to you mean by "my computer is not full"?  That sounds like you are talking about hard drive space which is not important in this case.  It is about memory.  A 4 MB image will take 1.2 GB when you multiply by 300.

I think the size of each image is about 2 MB, I'm using a PC with 8 GB of Ram and 512 of hard disk. Do you think the problem is due to the weight of too many images?

Despite being 8 GB, you'll never get to use that much due to the OS and the other programs.  I expect you can start seeing out of memory areas when you program approaches about 2GB, from my experience with programs that eat up memory.

It's possible that memory usage doubles as it combines the individual images into a larger video stream.  Also, you may not be running out of memory, but running out of contiguous memory.  It's possible that the combine sequence needs to be stored in one continuous chunk of memory, but with fragmentation, the remaining chunks of free memory aren't large enough.

I've barely touched Imaq stuff, so I don't know the underlying details of how it handles memory.
