read ou t in p arallel the Falcon 4M60 cam era is ca p able of reaching 60fp s. A tim ing
d iagram help s to exp lain this m od e of op eration.
Concurrent Mode Timing D iagram
In concu rrent m od e, a low -to-high transition in the EXSYN C signal starts the integration
tim e, and a high -to-low transition in the EXSYN C signal starts the read ou t of im age d ata.
As you r fram e p eriod ap p roaches the read ou t p eriod , by red u cing the Waiting tim e, the
Falcon 4M60 cam era ap p roaches its m axim u m fram e rate of 60 fp s.
In non -concu rrent m od e the integration and read ou t p eriod d o not ov erlap . While this
d oes im p act you r overall fram e rate, the m ain benefit is that in non -concu rrent m od e you
elim inate or m inim ize im aging artifacts. When p ossible, op erate the 4M60 cam era in non -
concu rrent m od e.
A tim ing d iagram help s to exp lain the non -concu rrent m od e op eration.
N on-concurrent Mode Timing D iagram
In non -concu rrent m od e, a low -to-high transition in the EXSYN C signal starts the
integration tim e, and a high -to-low transition in the EXSYN C signal starts the read ou t of
im age d ata. This is the sam e as in concu rrent m od e. The d ifference betw een these tw o
m od es is that you d o not p erform you r next low -to-high transition of EXSYN C u ntil
read ou t has com p leted . The w aiting p eriod can be red u ced to 0 second s by starting the
low -to-high transition im m ed iately after read ou t is com p lete. The read ou t tim e is a fixed
am ou nt of tim e that is d ep end ant u p on the m od e of op eration of the cam era, bu t is
typ ically arou nd 16.6 m s.
