View Full Version : Camera disturb/noise

December 7, 2015, 10:42:14
I am receiving randomly (but not very often) the disturb on the attached screenshot on the live stream of a DFx 61AUC02 camera.
Sometimes, in addition, the live stream is not starting at all.
The tool "Processor Idle State Manager" is installed.
Have you any idea of what can be the issue and some suggestions on what we can do to troubleshoot better this issue?

I am very sorry, but there is too less information for a diagnosis.

In order to narrow down your problem, I need some more information:
- Camera model :
- Serial number :
- Version of camera drivers (use Device Manager):

In case you use an USB 3.0 camera:
Use Windows Device Manager to query following:
- USB 3.0 Chipset (Intel, Renesas ....) :
- USB 3.0 controller driver manufacturer / version :

- Operating system :
- Computer model :
- Computer manufacturer :

- Used software (e.g. IC Capture 2.0) :

In case you have a programming problem:
- Used programming language:

- Error message : Incomplete image data transfer

Thank you in advance!

Sometimes on ICCapture the message "The device'DFx61AUC02 (33010287)' is live, but does not seem to deliver images. Please try to choose a different video format or try reconnecting your device to your computer' is shown1828
Sometimes images as the one attached are provided 1829

the damaged frames and frame drops are caused by incomplete image data transfer. It is absolutely not a camera problem. Maybe it can be a cable or if used, a hub problem.

It is extremely hard to narrow down the reason, if the Processor Idle State Manager does not work. What happens, if you use lower frame rates?

Also, what happens, if your note book is powered by power supply and not running on battery?
