What is meant by field of view?
Field of view (FOV) is the open, observable area a person can see through their eyes or via an optical device, such as a camera. In the case of optical devices, FOV is the maximum area that the device can capture. In other words, it answers the question: "How much can the device see?"
What is the field of view for a person?
Field of view (FOV) also describes the angle through which one can see that observable world. It refers to the coverage of an entire area, rather than a fixed focal point. In humans, the average field of view is about 170-180 degrees.
What is an example of field of view?
For example, a camera with a 90° horizontal field of view (HFOV) will see a 1000m wide section of a wall that is 500m in front of it. If you then adjust that camera's HFOV to only 1°, it will fill the screen with an 8.7m wide portion of that same wall.
What is field of view in a game?
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.
