The focal length determines the angle of view (AOV) through the lens,
as shown in Figure 3-2.
Figure 3-2: Angle of View calculation
Normally, the AOV is calculated based on the known focal length and
sensor size. This in turn determines the FOV, based on the distance
(L) to the object being captured. Figure 3-3 illustrates how the FOV
is calculated.
