Field of View

Field of view (FOV) refers to the extent of observable space visible to a person or device at any given moment. It's like the area you can see when looking straight ahead without turning your head. A wider FOV means you can see more in your peripheral vision, while a narrower FOV focuses your view on a smaller area. In cameras or displays, FOV affects how much of a scene is captured or displayed; a larger FOV shows more of the surroundings but may introduce distortion, whereas a smaller FOV provides a more zoomed-in view.
