to eliminate any black border surrounding the image. High values, both negative and positive can put the image out of sync.
• De-interlacing - is used to improve video stream image quality from analog devices. Select any of the following options
from the
De-interlacing
drop-down list. Select
None
if de-interlacing is not necessary;
Blending
for improved image quality
that is not as processor intensive;
Adaptive Interpolation
performs de-interlacing of the video stream by applying different
fi
lters on the image. This may give a better result than Motion Adaptive Interpolation in rare cases;
Motion Adaptive
Interpolation
performs de-interlacing of the video stream by applying different
fi
lters depending on the motion in different
parts of the image. This will in most cases result in the best image quality.
•
Antialiasing
will minimize distortion known as aliasing, which happens when a high-resolution image is represented at
a lower resolution.
• If your Axis product is to be connected in parallel with other equipment, disable
video termination
by selecting this option.
Failure to do so can impair the image quality.
