  2. Optimum HDTV viewing distance - Wikipedia

    en.wikipedia.org/wiki/Optimum_HDTV_viewing_distance

    The maximum viewing distance will provide a viewing angle of approximately 16 degrees with Best Buy's recommendation and approximately 20 degrees with Crutchfield's. The maximum viewing distance (minimum viewing angle) provided by Best Buy aligns with vision theory on the highest spatial frequencies perceivable by the human visual system. [41]

    After processing the film is cut down the centre and spliced together to give one roll of 8 mm wide film. The standard spool size for amateur use contains 25 ft of film, giving a total of 50 ft available for projection; at the usual filming speed of 16 frames per second this gives about four minutes of footage.

  4. Display size - Wikipedia

    en.wikipedia.org/wiki/Display_size

    The size of a screen is usually described by the length of its diagonal, which is the distance between opposite corners, typically measured in inches. It is also sometimes called the physical image size to distinguish it from the "logical image size," which describes a screen's display resolution and is measured in pixels. [1] [2]

    en.wikipedia.org/wiki/8_mm_film

    The frame size of regular 8 mm is 4.8 mm × 3.5 mm, and 1 meter of film contains 264 pictures. Normally, Double 8 is filmed at 16 or 18 frames per second. Common length film spools allowed filming of about 3 to 4 + 1 ⁄ 2 minutes at 12, 15, 16, and 18 frames per second.

    The sound was recorded 18 frames in advance of the picture (as opposed to 56 frames for standard 8mm). This short distance of just 3 inches facilitated the relatively compact size of the later sound cartridges. Some projectors used the balance stripe to provide a second channel for stereo sound. Super 8mm was also specified with an optical ...

    However, this optimal distance has the characteristic of being objective and simple to implement. The latest version of the ITU BT.500 uses it: "The design viewing distance (DVD), or optimal viewing distance, for a digital system is the distance at which two adjacent pixels subtend an angle of 1 arc-min at the viewer's eye". The TABLE 1-1 :

  8. Viewing cone - Wikipedia

    en.wikipedia.org/wiki/Viewing_cone

    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".

  9. Movie projector - Wikipedia

    en.wikipedia.org/wiki/Movie_projector

    35 mm movie projector in operation Bill Hammack explains how a film projector works. A movie projector (or film projector) is an opto-mechanical device for displaying motion picture film by projecting it onto a screen. Most of the optical and mechanical elements, except for the illumination and sound devices, are present in movie cameras.
