látószöget

Látószög refers to the angular extent of the observable world that is seen at any given moment. It is the total field of view that an observer can perceive without moving their head or eyes. This concept is fundamental in optics, visual perception, and photography. In humans, the horizontal látószög is approximately 210 degrees, while the vertical látószög is around 150 degrees, though these figures can vary. The binocular látószög, the area visible to both eyes simultaneously, is smaller than the monocular látószög (the field of view of a single eye).

The látószög is influenced by several factors, including the structure of the eye, particularly the shape and position of the eyeball, and the presence of obstructions. In photography and videography, látószög is determined by the focal length of the lens used. Wide-angle lenses capture a broader látószög, encompassing more of the scene, while telephoto lenses have a narrower látószög, focusing on a smaller, more distant area. Understanding látószög is crucial for composition in visual arts and for designing systems that mimic human vision, such as virtual reality headsets. It also plays a role in understanding peripheral vision and its importance in detecting movement and navigating environments.
