I was referring to computer animated scenes, but I guess it's also true
for real scenes. You should understand that there is a difference between
intra-frame and inter-frame motion blur. Intra-frame motion blur occurs
if an objects moves fast enough in vertical direction to be scanned in
different subsequent lines. Inter-frame motion blur happens if the scanning
device is too slow to keep up with object motion (after-image effects
caused for example by too slow shutter speed).
   In computer graphics, an animation sequence looks much more realistic
if you simulate motion blur. Many rendering systems neglect this, because
it's an expensive operation. My personal experience is that it is sufficient
to take into account the advancement of an object during each time step,
i. e. each half frame, regardless if it is perceived by the left or right
eye only. Obviously the brain doesn't separate here.
