Set Exposure Time

To set the camera's exposure time, use the Exposure Time parameter—a member of the Sensor Controls
set. This feature is only available when the Exposure Mode parameter is set to Timed. The allowable
exposure range is from 7 µs to 3,000 µs, dependent on the value of the internal line rate.
GenICam parameters:
Sensor Controls > Exposure Time (Timed Exposure Mode) > 8 µs to 3,000 µs.

Control Gain and Black Level

The cameras provide gain and black level adjustments in the digital domain for the CMOS sensor. The
gain and black level controls can make small compensations to the acquisition in situations where
lighting varies and the lens iris cannot be easily adjusted. The user can evaluate gain and black level by
using CamExpert.
The parameters that control gain and black level are grouped together in the Sensor Controls set.

Apply a digital addition after an FPN correction: ± 1/8 of the available range of
-32 to +31 in 8-bit mode, -128 to +127 in 10-bit mode, and -512 to +511 in 12-bit
mode.
Set the gain as an amplification factor applied to the video signal across all
pixels: 1x to 10x.
