9.1.3 Exposure Time
On exposure of the sensor, the inclination of photons produces a charge separation on
the semiconductors of the pixels. This results in a voltage difference, which is used for
signal extraction.

The signal strength is influenced by the incoming amount of photons. It can be increased
by increasing the exposure time (t
exposure
).
On Baumer VisiLine IP cameras, the exposure time can be set within the following ranges
(step size 1μsec):
