A field of view. In first person video games, the field of view or field of vision (abbreviated FOV) is the extent of the observable game world that is seen on the display at any given moment. It is typically measured as an angle, although whether this angle is the horizontal, vertical, or diagonal component of the field of view varies from ...
Angular field of view is typically specified in degrees, while linear field of view is a ratio of lengths. For example, binoculars with a 5.8 degree (angular) field of view might be advertised as having a (linear) field of view of 102 mm per meter. As long as the FOV is less than about 10 degrees or so, the following approximation formulas ...
Horizontal, vertical and diagonal field of view. It has been demonstrated that viewing a display that occupies a greater visual angle (also referred to as field of view) increases the feeling of presence. [6] More importantly, the wider the visual angle (up to a plateau at approximately 80 degrees), the greater the feeling of presence. [8] [9]
Angle of view can also be determined using FOV tables or paper or software lens calculators. [ 5 ] Log-log graphs of lens focal length vs crop factor vs equivalent focal length for 35 mm film or image sensor size (= the focal length multiplied by a crop factor) vs diagonal, horizontal and vertical angles of view for film or sensors of 3:2 and 4 ...
The magnitude of an object's solid angle in steradians is equal to the area of the segment of a unit sphere, centered at the apex, that the object covers.Giving the area of a segment of a unit sphere in steradians is analogous to giving the length of an arc of a unit circle in radians.
It should not be confused with the field of view (FOV), which is the angular cone perceivable by the sensor at a particular time instant. The field of regard is the total area that a sensing system can perceive by pointing the sensor, which is typically much larger than the sensor's FOV. [ 1 ]

The image sensor format of a digital camera determines the angle of view of a particular lens when used with a particular sensor. Because the image sensors in many digital cameras are smaller than the 24 mm × 36 mm image area of full-frame 35 mm cameras, a lens of a given focal length gives a narrower field of view in such cameras.
