In motion detection photography the only images captured are images whose
content is different from the previous image. For example, if you were
taking images of your yard using motion detection photography, the first
image would be captured into your movie file. If nothing changed in
the scene, then no further images would be captured. If however,
someone walked through your yard, all of the images of the person walking
through your yard would be captured to your movie file. If the person
then exited the yard, no further images would be captured until something
else in the yard changed.
This results in much smaller movies. This is ideal for long-term
surveillance applications. Everything "interesting" is captured but if
nothing is changing within the scene, no images are captured until something
again changes.
HandyAVI features a "sensitivity" control so that you can decide how much
frame-to-frame motion is required to trigger image capture.
HandyAVI also allows you to draw motion-sensitive rectangles on the
capture image so that frames will not be recorded unless motion occurs
within one or more of the rectangles. (Example, shooting a bird nest
and you don't want wind-blown background tree motion to be captured.
You only want to capture activity in the nest...)
