Why Field of View of Smartphone Camera Is Smaller Essay Example for Free

why issue of View of Smartphone television camera Is Smaller EssayField of view The field of view is the boundary of the observable world that is seen at any given moment. In photography, angle of view describes the angular utmost of a given scene that is imaged by a camera. These two can be apply interchangeably as field of view is proportional to angle of view.Mathematically, in triangle abc, side bc is the diametric of angle bac, thus length of bc depends on angle bac. In abc fruit drink, bac = dae, (Reciprocal angle). abc = aed (As bcde be intersects them, they are alternate angles) acb = ade (As bcde cd intersects them, they are alternate angles) Therefore, abc ade are similar triangles thus bc/de = ab/ae = ac/ad = k (some constant). Since, bc/de = k, = bc = k*de which implies that bc de (bc is proportional to de). This relation implies that, the field of view is proportional to the size of the sensor used in camera. Field of view also depends on the focal len gth of the lens.The above diagram shows that the Field of view is inversely proportional to the Focal Length of the lens used in a camera. Camera phones generally use sensor sizes in the range of 1/4 to 2/3. The caper of fitting a large sensor in a mobile device isnt only more or less the sensor itself, the greater challenge is the fact that the larger the sensor, the larger the lens need to be. This is because larger sensors take away one to get closer to their subject, or to use a longer focal length to get together the frame with that subject. So, to increase the field of view, we cant enlarge the camera sensor as we propensity or cant decrease the focal length of the lens. And thats why the field of view of smartphone camera/digital camera is smaller comparing to the field of view of human eyes.
