Deinterlacing
Deinterlacing is only applicable for the
Analog Optics Modules
. For these modules, the full
video frame is composed of two interlaced fields at a field frequency of 60 Hz. This means that
every second line of a full image is recorded at a time 16.6 ms later than the other half of the
lines. As a consequence, fast-moving objects will be recorded with a slight horizontal blur,
which is caused by the image segment in the even lines being shifted slightly from the image
segment in the odd lines.
To reduce the effects of the interlacing, uScope includes deinterlace filters, which will reduce
the visual appearance of the blurring caused by the interlacing by various algorithms. The
deinterlace method is selected in the Video>Deinterlace Video options dialog box.
The best deinterlace filter depends on the nature of the video image and should be chosen by
experimentation.

Time lapse
The Time lapse option is used to select the frame rate frequency to allow videos taken over a
long period of time to be compressed to a small file and played back at increased speed. The
time lapse options are set by clicking on the Time lapse…
button (
) at the bottom
left side of the main window. The Time Lapse Settings dialog box will appear.
Time Lapse Settings dialog box
Clicking on the Advanced Settings button will bring up a window that is identical to the Snap
Shot Settings window.
