If the camera's angle were always the same, an ideal viewing distance could be easily calculated. However, the camera's horizontal angle varies as the focal length of its lens changes. If the camera's sensor has fixed dimensions, a shorter focal length (wide angle) lens captures a wider angle of view, requiring the viewer to sit closer to the ...
In a technical context, the angular range is called viewing cone defined by a multitude of viewing directions. The viewing angle can be an angular range over which the display view is acceptable, [1] or it can be the angle of generally acceptable viewing, such as a twelve o'clock viewing angle for a display optimized or viewing from the top.

These expert-recommended 4K TVs, from top brands including LG, Samsung, and Sony, deliver an immersive viewing experience for streaming, gaming, and more.
The viewing cone refers to the effective viewing directions of an LCD display, as seen from the eye. This collection of angles resembles a cone. The concept has been introduced as an international standard ISO 13406-2, which defines it as the range of viewing directions that can safely be used for the intended task without "reduced visual performance".
In May 2012, NHK showed the world's first ultra-high-definition shoulder-mount camera. [51] By reducing the size and weight of the camera, the portability had been improved, making it more maneuverable than previous prototypes, so it could be used in a wide variety of shooting situations. [51]
A year later, Samsung and Phillips announced 'super ultra-wide displays', with aspect ratio of 32:9, for "iMax-style cinematic viewing". [8] Panacast developed a 32:9 webcam with three integrated cameras giving 180° view, and resolution matching upcoming 5K 32:9 monitors, 5120x1440. [ 9 ]
As abovementioned, a camera's angle of view depends not only on the lens, but also on the image sensor or film. Digital sensors are usually smaller than 35 mm film, and this causes the lens to have a narrower angle of view than with 35 mm film, by a constant factor for each sensor (called the crop factor).
Where the camera is placed in relation to the subject can affect the way the viewer perceives the subject. Some of these many camera angles are the high-angle shot, low-angle shot, bird's-eye view, and worm's-eye view. A viewpoint is the apparent distance and angle from which the camera views and records the subject. [2]
