Dear David<br>
<br>
Apparently your F416 CMOS camera is subdivided into eight vertical
stripes which are processed separately electronically. Stripe 5
and 6 (from 1-8) appear to have some electronic synchronization
problem. <br>
I would contact the manufacturer if I were you. (Tietz?)<br>
<br>
Cheers<br>
<br>
