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.
