Edmund Optics USB camera - Returning delayed image - Solution ActiveX driver?

[Martin.D]

Hi all,

We have a couple of high resolution USB cameras from Edmund Optics. We are using the Free NI driver for IMAQ but find that the image acquired is a couple of seconds old. We tried the Ivision from Hytek and still have the same delay. Both drivers use Direct Show if I remember correctly. The image is returned quickly but it shows what happened about 2 seconds ago. Any ideas?

We are now considering using the ActiveX component that came with the camera to avoid this delayed image issue. But this will involve a fair bit of work - Has anyone got any experience of the Edmund Optics ActiveX driver, or better still some LabVIEW VIs that wrap them up?

TIA

-Martin

Hi,
When you say high resolution, what is the resolution you are acquiring at? It will have to be a very high resolution for it to be delayed for 2 seconds. Are you using USB 1.0 or 2.0? Also, I assume you are using Labview to acquire these images, would it be possible to post your vi?
