Field-of-View Formulas:
3.2mm* x distance from camera (m)
Focal length (mm)
= Horizontal view (m)
2.4mm** x distance from camera (m)
Focal length (mm)
= Vertical view (m)
* Horizontal scanning area of pickup device (mm) in camera.
** Vertical scanning area of pickup device (mm) in camera.
Example: Wide angle view with lens at 6mm and viewed
object at 10m.
3.2mm x 10m
6mm
= 5.33m Horizontal view (m)
2.4mm x 10m
6mm
= 4.0m Vertical view (m)
