Orifice
Opening through which light reaches the sensor through a lens element.
The larger the opening or orifice, the more light reaches the sensor.
Opening the orifice lowers the depth of focus. The depth of focus
increases as the orifice is closed (larger number of orifices). Smaller
orifice openings make longer exposure times necessary. Short exposure
times require larger orifice openings.

for graphic display or recording of production data
Rising edge
Transition from logic 0 to logic 1 (rising).
Sensor

additional functions for image conversion, such as lighting control and
contrast correction, can be integrated directly into the chip.
Status-controlled
Detection of a signal (e.g. input) reacts to a logic 1 or logic 0.
TCP/IP
