Configuring image adjustments
Page 138
Epiphan Frame Grabber
The video capture application automatically adjusts image
capture settings every time it starts up. This image adjustment is
also repeated every 60 seconds during operation. So normally
you would not have to configure image capture adjustments.
However, you may have special requirements or for other reasons
have image quality problems that can only be fixed by making
image adjustments.
If image adjustments are required, you should make them in
small increments to avoid loss of image synchronization. If image
synchronization is lost, the video capture application will stop
capturing images. To start capturing images again you need to
exit from and restart the video capture application.
Note:
Because image adjustments are made automatically there
are no default image adjustment settings. Also, changing image
adjustments means making relative adjustments from the settings
auto configured by the system.
Sampling Phase
Adjust the sampling phase to change the horizontal resolution of
the image. In
, the sampling phase is properly adjusted
for Image A and the sampling phase for Image B is incorrectly
adjusted. As a result Image B is not as clear as Image A.
If the image in the video capture application window displays a
similar quality of image as shown in Image B, then select and
adjust the sampling phase in small steps until a sharper image is
displayed in the video capture application window.
