I'm acquiring time lapse images using Imaq USB, and I have a problem with one of the cameras i'm using :
The camera goes trough a "EZ Grabber USB 2.0 Video Capture-Convert" device, then in the usb on my computer.
I created a program taking either snap shots images, either movies (grab), and saves them in a folder.
Movie recording works perfectly using IMAQ USB Grab.
But when it's about recording snap shots, it doesn't work properly : 90% of the images are just black. (the 10% left are correct images)
even when I use the express VI "USB Acquisition" , I manage to have images approximately 10% of the times I click on "Acquire single image"
Changing the time of the loop doesn't do anything.
With an other device it works perfectly (other than "EZ grabber") but I have to use that one for my project.
Any ideas why this happens ? thank you and sorry for the poor english =$
I think its maybe a driver issue.
Can you try with the supplied software from Techgear.

My project is similar to yours as well. However, i am not able to acquire any image from the camera.
May i ask how did you do it?
