Function
Iris signal input
Comparator reference voltage input for shutter speed down
Comparator reference voltage input for shutter speed up
(a) Electronic iris characteristics
Shutter speed
: 1/60 to 1/100000 (s) (EIA)
1/50 to 1/70000 (s) (CCIR)
Iris steps
: 149 steps (EIA)
151 steps (CCIR)
Contraction ratio for one iris step : average 6%
Note) When LLIM = low, HLIM1 = low, and HLIM2 = low
(b) LLIM (low speed shutter limiter)
By setting the LLIM pin (Pin 61) high, the minimum shutter speed can be changed.
