Configuring exposure time
The exposure time can be set independently for the top and bottom areas. The actual exposure
time setting is defined by the following formula.
32.4812 µs × Exp2
Exp1 = 3 ms to 6 s (at sub-array 129.99 µs to 6 s)
Exp2 = Exp1 × 10
6
÷
32.4812 µs (round up at decimal point)
The actual exposure time setting for Rapid Rolling Mode is defined by the following formula.
10 µs × Exp2
Exp1 = 1 ms to 2 s (at sub-array 40 µs to 2 s)
Exp2 = Exp1 × 10
6
÷
10 µs (round up at decimal point)
Available setting range of the exposure time is the following.
Free running mode
3 ms to 6 s
1 ms to 2 s (Rapid Rolling Mode)
Free running mode (at Sub-array)
129.99 µs* to 6 s
The same exposure time is set for the top and bottom areas
when the exposure time is shorter than 3 ms .
40 µs* to 2 s (Rapid Rolling Mode)
The same exposure time is set for the top and bottom areas
when the exposure time is shorter than 1 ms.
External trigger mode
The exposure time can be set
independently for the top and bottom
areas with edge trigger mode or start
trigger mode.
3 ms to 6 s
1 ms to 2 s (Rapid Rolling Mode)
Note
* 129.99 µs and 40 µs (Rapid Rolling Mode) for the Free running mode (at Sub-array) is the
minimum exposure time when sub-array is set to 4 lines vertically. The minimum exposure time
vary depend on vertical line number of sub-array setting.
