Full-color mode is distinguished by: each pixel contains its own values; a full-color render takes about three times as long as color mapped render. Anti-aliasing, transparency, and texture mapping are possible only in this mode. Full-color mode makes possible such things as transparency, texture mapping, and anti-aliasing.

a) A wave which has been reflected at one or more points in the transmission medium, with sufficient magnitude and time difference to be perceived in some manner as a wave distinct from that of the main or primary transmission. Echoes may be either leading or lagging the primary wave and appear in the picture monitor as reflections or “ghosts.” b) Action of sending a character input from a keyboard to the printer or display.

The minimum rate of presentation of successive images of a motion picture that allows motion to seem smooth, rather than jerky. The fusion frequency is almost always lower than the flicker frequency.
As it applies to the rate at which images are presented, rather than the rate at which they were shot, material that appears to be at or above the fusion frequency when viewed at normal speed may be below it when viewed in slow motion. Techniques to smooth motion presented at a rate below the fusion frequency have been developed for such purposes as computer-assisted animation; these are sometimes called in-betweening techniques. See also Judder.

An HDTV film-complement format introduced by Sony in 1998. 1920 x 1080, progressive scan, 24 fps, 4:4:4 resolution. Using a 1/2-inch tape, the small cassette (camcorder) will hold 50 minutes while the large cassette will hold 156 minutes. E-Cinema’s camcorder will use three 2/3-inch FIT CCDs and is equivalent to a film sensitivity of ISO 500.
The format will compress the electronic signal somewhere in the range of 7:1. The format is based on the Sony HDCAM video format.
