20.3 mvBlueFOX-[Model]221 (0.8 Mpix [1024 x 768]) 209
1. Time needed to send data to the CCD controller depending on what is changed
exposure : abt 2..3ms
window: abt 4..6ms
trigger mode: from 5..90ms,
varies with oldmode/newmode combination
2. Time to initialize (erase) the CCD chip after reprogramming this is fixed, abt 4.5 ms
So for example when reprogramming the capture window you will need (average values)
t
regprog
= change_window + init_ccd
t
regprog
= 5ms + 4.5ms
t
regprog
= 9.5ms
