Important
The exposure time will be longer for larger values. This may cause the image to blur if the object is moving fast.
If the Sensor is used on a high-speed line, check that the images are not blurred under actual operating
conditions.
Taking Clear Images of Moving Objects
For quick moving objects, the effect of blurring can be reduced by decreasing the exposure time.

The image becomes darker the smaller the exposure time. If the Sensor is used in a dark environment, make
sure that the darkness of the image does not cause the measurements to be unstable.
