Field of View (FOV)
Field of view (FOV) is the angular portion of visible space which is comprised into the image region. The FOV of the human eye is around 150°. The camera FOV depends both on the size of the camera sensor and the geometry of the lens. The camera focal length determines the field of view falling within the sensor area, thus determining also the magnification factor of the image. A shorter camera focal length produces a wider FOV, while a longer focal length produces a smaller FOV.
