Everything you can see when you look through binoculars is the field of view. Binoculars with larger fields of view allow you to view a larger area.
(FOV) the angle of the cone of vision of a lens; the usual human FOV is approximately 150
The maximum visible space seen through an optical instrument or lens.
The angular width of the sky when viewed by an optical telescope.
The size of the "window" you see through when looking through binoculars.
The size of the area that can be seen while looking through an optics device is referred to as the field of view. The angular field of view is indicated on the outside of the binocular, in degrees. The linear field of view refers to the area that can be observed at 1,000 yards, and is expressed in feet. Field of view is related to magnification, with greater magnification typically resulting in a smaller field of view.
Field of View defines the width of your view as an angle with its apex at your viewpoint and the ends at the sides of the view. The effect of changing FOV is similar to changing the lens on a camera. As the FOV gets larger you see more of your scene and the perspective becomes distorted, similar to using a wide-angle lens. As the FOV gets smaller you see less of your scene and the perspective flattens, similar to using a telephoto lens.
35mm cameras produce rectangular pictures (36 x 24mm negatives) and therefore the field of view is greater for the longer dimension. Generally when someone refers ambiguously to the field of view of a 35mm image they are referring to the field of view along the longer of the two dimensions, regardless of which way up the camera was (portrait or landscape).
An angle that, together with the orientation and position, determines which parts of the scene are visible in the window at any given time
Is the width of the area (in degrees) that can be seen at a given distance (usually measured at 1000 yds). Sometimes called, "Angular Field", a large field of view permits you to see a large area at one time, and it also enables you to follow a moving subject with ease. The smaller the magnification the greater the field of view.
The side-to-side measurement of the circular viewing field or subject area. It is defined by the width in feet or meters of the area visible at 100 yards or meters. A wide field of view makes it easier to spot game and track moving targets. Generally, the higher the magnification, the narrower the field of view.
The solid angle through which an instrument is sensitive to radiation. Owing to various effects, diffractions, etc., the edges are not sharp. In practice they are defined as the 'half-power' points, that is, the angle outwards from the optical axis, at which the energy sensed by the radiometer drops to half its on-axis value.
The portion or area of sky that can be seen within a telescope/eyepiece.
This is the total height and width of the view seen through the lens.
The region "seen" by the camera lens and recorded on the film. The same phrase is applied to such other equipment as radar and radio antennas.
A view's height and width that can be viewed through a lens
Refers to the angle at which a camera is able to produce a visible image. This angle can be described in terms of diagonal, horizontal, or vertical degrees. A camera's field of view is determined by its lens configuration. Fixed lenses have set fields of view, while cameras with varifocal or power zoom lenses have adjustable fields of view.
The image area produced by any camera and lens combination (See focal length ) .
(FOV) - defined as the size of the two or three dimensional spatial encoding area of the image. Usually defined in units of cm2.
The area of the subject covered by the lens's angle of view.
the area that is visible (as through an optical instrument)
The width and height or area desired to be covered by one camera. This area is determined by the focal length of the lens on the camera and the distance the camera is mounted from the scene.
The width of the area seen at a certain distance, usually 1000 yards. Tips: A large field of view is good for a general surveying of an areas- good for hunting. A large field of view is always accompanied by a lower magnification. A high magnification is good for spotting specific objects but bad for quick, easy searches.

The total field, measured as an angle, within which objects viewed by a thermal imager. Narrower FOVs generate more life-size images and distances, while wider FOVs place more image on the display. The most common FOV for fire service TIs is about 50º.
The distance across an image, typically in centimeters. The field of view in the frequency and phase encoding directions may be different. [ Chapter 7
the width of the view measured in angular degrees that is visible at any one time on the screen. (The field of view of a normal pair of binoculars is usually about 5° and the moon is 0.5° across as seen from Earth).
largest solid angle where incident light can form an image. Since a human's two eyes have overlapping 140 degree FOV, binocular or total FOV is roughly 180 degrees in most people. A feeling of immersion arises when the FOV is greater than roughly 60 to 90 degrees.
The extent of an object which a lens system actually images, usually expressed in degrees (e.g: 5°) or so many metres wide at a 1,000 metres distance.
The maximum area in angular field that can be seen through a lens or an optical system. (ref. Angle of View)

The horizontal or vertical picture size at a given distance from a camera to the subject.

The portion of the scene in front of the camera represented within the limits of the camera aperture at the focal plane. Area of field thus varies with focal length of lens and camera-to-subject distance.
The angle in degrees of the visual field. Most HMDs offer 60 to 90 degrees FOV. Since our two eyes have overlapping 140 degree FOV, binocular or total FOV is roughly 180 degrees in most people. A feeling of immersion seems to arise with FOV greater than 60 degrees.

The range of angles that are scanned or sensed by a system or instrument, measured in degrees of arc.
that area defined by the constraints of an optical system; the stronger the optical system, the smaller the field of view.
The two dimensional area which can be seen through the optical imaging system. In the case of a zoom optical system, you have a varying field of view. At the highest magnification, you have a smaller field of view. At the lowest magnification, you have the largest field of view.
The view of the camera - in relation to the angle of view and distance of the object from the lens.
The field of view of a camera is the angle that the camera can see. A large field of view will fit more into the view, but will look distorted and a small field of view will tend to make the view more flat, tending towards an orthographic view. There are two fields of view in JetStream - vertical and horizontal. Editing one will change the other and the two are related by the viewpoint's aspect ratio.
The maximum view angle of a lens. The number supplied by a manufacturer is the Apparent FOV. The True FOV (or Actual FOV)is found by dividing the Apparent FOV by the magnification.
The total instantaneous area or solid angle that can be viewed by a sensor.
The basic parameter in a video system, field of view defines the rectangular area of the viewed object that is displayed on the monitor. FOV depends on the angular magnification of the optics in front of the camera, and on the linear magnification, or ratio of monitor size to CCD format size. Magnification by itself is not a basic system parameter.
Usually measured in degrees, this is the angle that a lens can accept light. For instance, the human eye's horizontal field of view is about 175°.
The maximum viewed image achieved by a lens referred to as an angle-of view.
The size of the piece of sky that a telescope can look at at one time. This is usually given as an angle.

FOV. The width, height or diameter of a scene to be monitored. Usually determined by the focal length of a lens, the sensor format and the distance to the objects.
Sometimes abbreviated "FOV", this is the diameter of the circle of light that you see when looking into a microscope. As the power increases, the field of view decreases. You can measure this by placing a clear metric ruler or a stage micrometer on the stage and counting the millimeters from one side to the other. Typically you will see about 4.5mm at 40x, 1.8mm at 100x, 0.45mm at 400x and 0.18mm at 1000x. See also micrometer.
The field of view (FOV) is the part which can be seen by the machine vision system at one moment. The field of view depends from the lens of the system and from the working distance between object and camera.
The amount of the scene visible to the camera, defined as the camera's aperture divided by its focal length. Wide-angle lenses have a large field of view, while telephoto has a small field of view.
