3-8 Using WebCam Control with the WDM driver
If you are using fluorescent lighting, move the White Balance slider so that the image will not
have a tint of green or magenta.
Banding filter
Under fluorescent lighting, the frequency of the power supply to the light may cause “banding”
in the video captured by the camera. “Banding” refers to the appearance of bands that are of a
brightness or shade different from that of the original display.
To filter out these distortions, enable the banding filter by moving the Backlight Comp slider
to the right (value 1). If you are using incandescent lighting, you can disable the banding filter
by moving the slider to the left (value 0).
Achieving the Best
Frame Rate
Here are a few tips for increasing the frame rate:
❑
Choose a smaller image size.
❑
Configure the camera to operate in I420 mode.
❑
Disable compression.
❑
Close all unnecessary applications.
❑
Before capturing video to an AVI file with Video Blaster WebCam Control, use the Windows
Disk Defragmenter application to defragment your hard disk drive.
❑
If your WebCam 3 is daisy-chained with another USB device to the USB port or if it shares
a USB hub with other devices, make sure that none of the other devices is active when you
are capturing video. The total bandwidth of the USB port on your PC is shared by all the
active USB devices, and operating WebCam 3 along with another USB device on the same
port can lower the maximum possible frame rate.
