Troubleshooting
10.1.
Focus Issues
If the video appears out of focus, check that the lens is focused properly. Typically, a lens is pre-installed
and is pre-focused for an optimal head shot distance of 3.5 to 7 feet from the camera. If your subject is
out of that range then you will need to make a slight adjustment to the lens.
Unlock the locking screw on the lens and rotate the lens very slightly watching to see if the subject comes
in to focus. When you have the proper focus for the distance, lock the locking screw securely. It is possible
for a very tight locking twist to cause a slight focus shift, so take care to lock the screw gently and to
recheck that the image is still property focused.
10.2.
Noisy or Grainy Video
Be certain that there is enough light in the room where the images are snapped and that your subject is
not located directly under a bright spotlight.
10.3.
Poor Color Reproduction
Try the various white balance choices in the event that you have strange lighting conditions. The camera’s
default setting is set for standard fluorescent lighting. If the camera is setup outdoors, you may require a
more optimal white balance.
10.4.
Dark faces
Subjects should not be placed in front of overly bright backgrounds, such as a window with sunlight
streaming through it. At the same time, be certain that the environment provides enough overall light.
Additionally, a solid light grey backdrop is preferred for headshots.
10.5.
Reflections
Take care that the camera lens is at approximately the same height as the subject’s nose. There should
not be a high light point source in the ceiling angled in to the subjects face. This may cause glasses to
reflect or shadows to appear on the face. A hot white dispersed light aimed directly on to the face is
sometimes needed for an ideal image capture.
10.6.
Video display shows a green or black color
For Win XP, update USB 2.0 Host driver to the latest driver from the Microsoft
®
web site. For Win 98 SE
and Win Me, an OS upgrade to Win XP with latest Microsoft
®
USB 2.0 Host driver is necessary.
10.7.
Video display appears inoperable or exhibits a slow frame rate
Verify the system complies with the minimum system requirement specification.
Try a different USB 2.0 port in your system.
Try to lower the video quality, by going to Options > Capture Pin > quality > change the value to 0.
Try a different video format, YUY2 or I420.
Verify VGA card supports Direct Show, and upgrade VGA card to the latest driver.
10.8.
An incomplete or scrambled video display on USB 1.1 port
Verify the system complies with the minimum system requirements.
Unplug all of USB1.1 devices from the system.
Verify that the USB1.1 video camera device is the only USB device in the system.
10.9.
Cannot see video
Unplug and plug the camera in again.
Reinstall the USB Video driver. Follow the procedures below on how to reinstall the camera under different
scenarios.
