Angle-of-view is the breadth of a subject as seen by a camera system. The angle of view indicates the image size in degrees, when the objective is set to ∞. The field of view is dependent upon the focal length of the lens, the image sensor size, the lens distortion, and the lens image circle.

The first is the rectilinear lens, This is the typical lens which renders all straight lines in the subject as straight lines in the image (see diagram below). The angle of view of course depends from the focal length. This calculator provides the camera's field of view based on an image sensor and a lens. Filming Aspect Ratio. It can also provide the calculation steps and how the right triangle looks. At a small focal length, the angle is large (wide-angle), at a large focal length, the angle is small (tele). Tips to increase FOV. There are two types of lens you'll find in photographic use. The pixel width cannot therefore be used in the image circle calculation. It's pretty much the way our eyes see things and it's exactly the way a pinhole cameras sees things. Enter the image circle (diagonal width) of the sensor in and the focal length of the lens to calculate the Horizontal Angle of View for different types of lenses. In reality, lenses aren’t perfect, you will therefore see visual deviations (e.g a barrel effect on a wide angle rectilinear lens), this will also translate to variances in focal length and angles of view. Also explore many more calculators covering geometry, math and other topics. You can use either an aspect ratio, or, if you do not know your screen's … The following calculations have been put together to assist with choice of lenses, by determining the horizontal angle of view that will be generated for a lens with a given focal length, or by showing the focal length you would need to find in order to achieve a given horizontal angle of view. Image Connect Photographer Matching Service, Monochrome Continuous Feed Digital Presses, Corporate Social Responsibility Guidelines, Environment & Sustainability Initiatives Home. They are equal to the ones we calculated manually: β = 51.06°, γ = 98.94°; additionally, the … Horizontal viewing angles. CCTV Calculator is a tool designated for camera system basic parameters determination and testing. It enables easy calculation of an appropriate lens focal length, camera viewing angle, IP camera bandwith, storage capacity for records archiving and of other camera system parameters. tan ( / 2 ), Orthographic fisheye lens : R = f . For normal and telephoto use, a rectilinear lens is ideal, however for extreme wideangle use it isn't. The Angle of View required from an imaging system is the same as the Field of View. Find the right lens quickly & easily with the Kowa lens calculator. The field of view is dependent upon the focal length of the lens, the image sensor size, the lens distortion, and the lens image circle. Introduction. For a shorter distance (closer object), the angle becomes smaller. Horizontal/Vertical FOV Calculator This calculator will convert an aspect ratio and horizontal FOV to a vertical FOV, useful for setting your favorite horizontal FOV in a game that uses vertical FOV. Results. THX requires that the back row of seats in a theater have at least a 26 degree viewing angle and recommends a 36 degree viewing angle. Angle of View Calculator.

It helps me keep adding to this site when you get yours from those links, too. Lens Focal Length (mm)*. It enables easy calculation of an appropriate lens focal length, camera viewing angle, IP camera bandwith, storage capacity for records archiving and of other camera system parameters. To calculate the angle, we need an equation for the arc length: From an arc length equation, we can calculate γ angle: Example: FOV: 125m/1000m. γ – angle of view.

The angle that he labels as the angle of view is the half-angle or "the angle that a straight line would take from the extreme outside of the field of view to the center of the lens;" he notes that manufacturers of lenses use twice this angle. Standard film has a width of 35 mm, the APS-C-sensor of a digital camera has a width of 23 mm. The results list a number of a different lens types: A rectilinear lens is what we would generally use in filming and photography, as the projected image appears the same as it looks to the naked eye.
