Field of view (FOV) refers to the extent or scope of what is visible or can be seen within a specific range or angle in a given viewing frame or optical device. It is commonly used in the context of various technologies such as photography, microscopy, video games, virtual reality, and optics.
In photography and cinematography, FOV pertains to the angular extent of a scene captured by a camera or lens. It determines the width of the image frame, with a wider FOV encompassing a larger area and a narrower FOV focusing on a smaller portion.
In video games and virtual reality, FOV defines the extent of the game world or simulated environment that is visible to the player. A wider FOV provides a broader view and a greater sense of immersion, while a narrower FOV limits the player's visual field but can sometimes enhance focus and detail.
In optics, FOV describes the angular area visible through an optical instrument, such as binoculars, telescopes, or microscopes. It denotes the maximum angle between two lines of sight, which encompass the entire field of vision within the instrument.
Overall, the field of view represents the range of vision or perspective that can be perceived by an individual or captured by a device. It plays a crucial role in determining the extent, context, and level of detail that is visible or accessible within a given frame or field of observation.
