Question

Quizplus · Accepted Answer

The FOV is determined by the angle at which the light enters the lens and reaches the camera sensor. In Figure 1, the FOV is 30 degrees, while in Figure 3, the FOV is 120 degrees. This means the FOV is enlarged by a factor of 4. Thus, the best choice is D) 10,000, which is 4 squared (since the FOV is enlarged by a factor of 4, we need to square 4 to get the correct enlargement factor).
