Exposure Time - Basler ase Installation And Setup Manual

You can increase the brightness of the image by increasing the camera's black level setting.
Normally, you should increase the black level setting only as much as is necessary to make de-
tail visible in the darkest portions of an image. Increasing the black level too much may cause
a loss of contrast in the image.
In the captured images below, notice how brightness increases as the black level increases.
Also notice that at very high black levels, the overall image loses contrast.
Low Black Level

Exposure Time:

The exposure time setting determines the time interval that the sensor is exposed to light during
each frame acquisition. Increasing the exposure time is a good way to increase brightness. But
keep in mind that increasing exposure time too much may reduce the camera's maximum allowed
frame acquisition rate.
Gain:
Gain amplifies the values output by the pixels in the camera's sensor.
Increasing gain will increase the image brightness.
You can also increase the contrast in the image by increasing the camera's gain setting.
Unless your application requires extreme contrast, make sure that detail remains visible in the
brightest portions of the image when increasing gain.
Set the gain only as high as is necessary.
Because the gain function amplifies the signal and the noise proportionately, increasing the gain
does not improve the signal-to-noise ratio.
