[3dem] Camera CMOS malfunction

[Marin van Heel]

Dear David

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.
I would contact the manufacturer if I were you. (Tietz?)

Cheers

Marin
