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.
Exp1 = 3 ms to 6 s (at sub-array 129.99 µs to 6 s)
Exp2 = Exp1 × 10
The actual exposure time setting for Rapid Rolling Mode is defined by the following formula.
Exp1 = 1 ms to 2 s (at sub-array 40 µs to 2 s)
Exp2 = Exp1 × 10
Available setting range of the exposure time is the following.
Free running mode
Free running mode (at Sub-array)
External trigger mode
The exposure time can be set
independently for the top and bottom
areas with edge trigger mode or start
trigger mode.
* 129.99 µs and 40 µs (Rapid Rolling Mode) for the Free running mode (at Sub-array) is the
Note
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.
