A multi-resolution image format in which the image is stored as a series of independent arrays. Developed by Kodak, Hewlett-Packard, Live Picture, Inc., and Microsoft and introduced in June 1996.

A) Flicker occurs when the refresh rate of the video is too low and the light level on the display begins to decrease before new information is written to the screen to maintain the light level. To prevent the human eye from seeing flicker, the screen refresh rate needs to be at least 24 frames per second. b) A rapid visible change in brightness, not part of the original scene. See also Flicker Frequency, Fusion Frequency, Judder, Large-Area Flicker, and Twitter.

As used herein, the entire area viewed by a television camera with the viewed area being uniformly white or any single specified colour or any shade of gray.

The minimum rate of change of brightness at which flicker is no longer visible. The flicker frequency increases with brightness and with the amount of the visual field being stimulated. In a recent study, a still image flashed on and off for equal amounts of time was found to have a flicker frequency of 60 flashes per second at a brightness of 40 foot lamberts (fL) and 70 at 500. Television sets generally range around 100 fL in peak brightness (though some new ones claim over 700). The SMPTE recommends 16 fL for movie theatre screens (though this is measured without film, which reduces the actual scene brightness by at least 50 percent). One reason for interlaced scanning is to increase television’s flashing pictures to the flicker frequency, without increasing bandwidth.

Mass-storage device that uses a flexible (floppy) diskette to record information. See Disk.

Special effect in which the picture is either horizontally or vertically reversed.

Graphical representation of programme logic.
Flowcharts enable the designer to visualise a procedure. A complete flowchart leads directly to the final code.
Industry:Entertainment
Logic node that has no active outputs. Three-state bus lines, such as data bus lines, float when no devices are enabled.

Refers to a tripod mount that contains lubricating fluid which decreases friction and enables smooth camera movement.
Industry:Entertainment
Technique used to represent a large range of numbers, using a mantissa and an exponent. The precision of the representation is limited by the number of bits allocated to the mantissa.
