a) Projectors, multiplexers, and cameras connected for the purpose of transferring film to video. b) A device that transfers a film image to a video image. It is also know as a Telecine chain.
Industry:Entertainment
A device used to remove or pass certain frequencies from a signal.
Low-pass filters pass the low-frequency content of a signal while highpass filters pass the high -frequency content. A bandpass filter passes frequencies within a certain “band.”
Industry:Entertainment
Distortions introduced by filters. The most common visual artifacts introduced by filters are reduced resolution and ringing.
Industry:Entertainment
A low-pass filter with a steep cut-off (such as 20 dB/octave or greater), such that a negligible amount of higher frequency information passes. The filter typically has uniform group delay.
Industry:Entertainment
A low-pass filter providing a gradual attenuation of the higher frequencies. Strictly the attenuation should follow the curve V = e^(–af^2). But the term is also applied to attenuation functions that only qualitatively resemble the precise power function.
Industry:Entertainment
In addition to the familiar optical filters for modifying spectral energy distribution, and thereby color rendition, optical filters are also produced as low-pass filters for spatial detail in an optical image, eliminating high-frequency information that would exceed the Nyquist limit of the system and produce excessive aliasing. Many of these filters are cut from optically birefringent crystals and function by providing multiple images slightly displaced one form another so that fine detail is blurred (i.e., low-pass filtered).
Industry:Entertainment
A digital filter that is, in general, better than analog filters but also more complex and expensive. Some specialized filter functions can only be accomplished using a FIR.
Industry:Entertainment
At this writing, the hottest new technology in video. FireWire is a special high-speed bus standard capable of over 100 Mbits/sec sustained data rate.
Industry:Entertainment
Program stored in ROM. Normally, firmware designates any ROM-implemented program.
