WebIn a camera lens, the focal point is located on the sensor if the image is “in focus”. The Field of View (FOV) of a camera and lens is a measure of the spatial dimensions that the camera and lens can include in an acquired image. It is correctly specified in terms of the angle between the two edges of the camera image. WebNov 11, 2024 · FoV is determined by the camera lens and sensor size. The human eye has an average field of view of about 170-180 degrees. In photography, you can change the field of view by changing our lens. A wide-angle lens will allow you to capture more of a scene, while using a telephoto lens or moving the camera will decrease the field of view.
